Income Tax Return Service For Buying House in Dhaka

Buying a house in Dhaka is not just a matter of agreeing a price with the seller and signing a deed. Bangladesh's tax administration, the National Board of Revenue (NBR), has steadily tightened the link between property ownership and income tax compliance. A buyer who does not already hold a Taxpayer's Identification Number (TIN) and an up-to-date income tax return is likely to run into friction at the Sub-Registrar's office, at the bank when arranging payment, or later during a tax audit when the source of the money used to buy the property is questioned. This is why "Income Tax Return Service for Buying a House in Dhaka" has become one of the most frequently needed pieces of legal-and-tax support for first-time buyers, returning Non-Resident Bangladeshis (NRBs), and even seasoned investors adding a second or third property to their portfolio.

The service itself sits at the intersection of two separate government systems: the NBR's income tax administration (which issues TINs, processes annual returns, and requires wealth statements from certain taxpayers) and the Sub-Registrar's office under the Registration Act, 1908 (which registers the sale deed and physically transfers legal title). A buyer needs both systems to work in their favour at the same time — a valid TIN and filed return on the tax side, and a clean, correctly stamped deed on the registration side. Missing either one can stall or permanently complicate a purchase.

This guide explains, in plain language, exactly what Bangladeshi law requires of a house buyer in Dhaka from a tax perspective, what documents and disclosures are involved, what the total cost of compliance looks like, and how long the process realistically takes. It also explains what can go wrong — and how it can be fixed — if a buyer proceeds without proper tax documentation.

Income Tax Return Service for Buying a House in Dhaka is a tax-compliance support service that prepares a prospective property buyer's income tax record — TIN registration, current and, where necessary, prior-year return filing, and a wealth statement showing the source of the purchase funds — so that the buyer can lawfully complete a property registration with a Sub-Registrar's office and, where relevant, satisfy a bank, developer, or the NBR that the transaction is properly disclosed.

In practice, the service covers three connected pieces of work. First, if the buyer does not already have a TIN, the service registers one through NBR's e-TIN portal. Second, it prepares and files the buyer's income tax return for the relevant assessment year (or years, if returns have been missed), producing the acknowledgement and system-generated certificate that function as Proof of Submission of Return (PSR). Third, it prepares a wealth statement (Form IT-10B) that reconciles the buyer's declared assets, including the new house, against their declared income and other legitimate sources of funds such as savings, remittances, gifts, loans, or the sale of another asset.

This is distinct from — but closely connected to — the separate legal process of registering the sale deed itself at the Sub-Registrar's office, which is governed by the Registration Act, 1908, and which involves its own stamp duty, registration fee, and local taxes. A buyer typically needs both pieces working together: clean tax documentation on the NBR side, and a correctly executed, stamped deed on the registration side.

Who needs this service? Overwhelmingly it is first-time property buyers in Dhaka who have never filed a return before; salaried professionals who have a TIN but have never disclosed a large asset purchase; Non-Resident Bangladeshis (NRBs) who want to buy a flat with remitted foreign income and need their tax status regularised in Bangladesh; and self-employed individuals or small business owners whose income sources need to be properly reconciled against the price of the house they are buying. For all of these buyer profiles, the underlying legal principle is the same: Bangladesh's income tax framework increasingly requires that a person's declared income and wealth explain how they came to own valuable assets, and property is the single most visible and most commonly checked asset class.

Bangladesh's tax authority has, over the last decade, systematically expanded the number of everyday financial and legal transactions that require a person to first prove they are a compliant taxpayer. Property is one of the clearest examples of this policy, for a simple reason: a house or flat is a large, traceable, publicly recorded asset. Unlike cash or informal savings, a registered property leaves a permanent paper trail at the Sub-Registrar's office and, increasingly, in NBR's own data systems. This makes property purchases a natural checkpoint for verifying that a person's declared income is consistent with their actual wealth.

The Income Tax Act 2023, which replaced the earlier Income Tax Ordinance 1984, formalised this checkpoint concept through its Proof of Submission of Return (PSR) requirement. Under Section 264 of the Act, a wide list of services and transactions — ranging from obtaining a loan above a certain threshold, to becoming a company director, to renewing a trade licence, to a range of registration and licensing services processed by government offices — cannot be completed unless the applicant furnishes a valid PSR or an exemption certificate from the NBR. Property registration and other high-value asset transfers fall within the spirit and, depending on the specific NBR circular in force for the relevant year, often the letter of this list. Because the exact threshold value has been adjusted by successive Finance Acts, buyers should always confirm the current figure with the Sub-Registrar's office or a tax professional before assuming a transaction falls outside the requirement.

Separately, and just as importantly, NBR's assessment officers have the power to question any asset — including a newly purchased house — that does not appear to be explained by the taxpayer's previously declared income and wealth. This is sometimes referred to informally as an "unexplained investment" issue. If a buyer purchases a house without ever having filed an income tax return, or files a return that shows income far too low to plausibly fund the purchase price, the NBR can treat the unexplained portion of the property's value as undisclosed income and assess tax, and in some cases penalty, on it. Filing a return and a wealth statement before or immediately after the purchase — showing clearly where the money came from — is the standard, legitimate way to prevent this exposure.

Finally, banks, developers, and even some sellers now routinely ask for a TIN certificate as a matter of internal compliance policy, independent of any strict legal obligation, because it reduces their own exposure to anti-money-laundering concerns. Taken together, these three forces — the PSR requirement, the risk of an unexplained-investment assessment, and market practice among banks and developers — mean that having a properly filed income tax return before buying a house in Dhaka is now close to a practical necessity, even in situations where the law does not make it explicitly and unconditionally mandatory for every single buyer.

The primary legal instrument behind this service is the Income Tax Act 2023, enacted on 22 June 2023 to replace the Income Tax Ordinance 1984. Most of the substance of the older law carried over, but the new Act reorganised and, in places, tightened compliance mechanisms — the PSR regime being one of the clearest examples.

Section 264 — Proof of Submission of Return

Section 264 of the Income Tax Act 2023 provides that, notwithstanding any other provision of the Act, a person must furnish a Proof of Submission of Return in a defined list of cases before the relevant authority can process, approve, sanction, or register the transaction in question. Under sub-section (2), a PSR can take one of several forms: an acknowledgement receipt of a return submitted within the relevant tax year, a system-generated certificate containing the taxpayer's name, TIN and assessment year (downloadable from NBR's e-Return portal after filing), or a certificate issued directly by a Deputy Commissioner of Taxes (DCT) confirming the same details. The listed cases in sub-section (3) include applying for a bank loan above a stated threshold, becoming a company director or sponsor shareholder, obtaining or renewing an import or export registration certificate, obtaining or renewing a trade licence in a city corporation or paurashava area, and a range of other registration, licensing and payment-processing services specified by the Board from time to time. Sub-section (5) is the enforcement mechanism: it directs that the officer responsible for processing, approving, or registering any of these transactions must not do so unless the PSR is furnished, or the applicant produces a Board-issued exemption certificate.

Because the precise list of PSR-triggering transactions, and the specific value thresholds attached to property and loan transactions, are updated periodically through Finance Act amendments and NBR statutory regulatory orders (SROs), the exact figure applicable to a given property purchase can change from one assessment year to the next. Aeenx checks the currently applicable NBR circular for every client engagement rather than relying on a fixed number, and we recommend any buyer do the same — either by checking directly with NBR or by consulting a tax professional — before assuming a specific transaction is or is not covered.

Registration Act, 1908

On the property side, the Registration Act, 1908 requires that deeds of sale, gift, and other instruments transferring rights in immovable property be registered with the Sub-Registrar of the area where the property is located in order to be legally valid and enforceable. This Act does not itself impose an income tax compliance condition, but in practice Sub-Registrar's offices, acting on NBR guidance and administrative instructions, request a TIN certificate as a standard supporting document for the buyer (and often the seller) before accepting a deed for registration. Where the transaction value crosses the applicable PSR threshold, the buyer's PSR is requested alongside the TIN certificate.

Wealth Statement Obligations

Separately, under the return-filing rules that apply to individual taxpayers whose income or asset profile meets certain conditions (broadly, business or professional income, or total assets above a specified value at the end of the income year), the taxpayer must submit Form IT-10B (statement of assets, liabilities and expenses) alongside the main return. Acquiring a house during the income year is exactly the kind of change in asset position this form is designed to capture, and it is the document that formally reconciles "where the money for the house came from" with the taxpayer's declared income for the year.

A TIN is the mandatory starting point: a person cannot file a return, obtain a PSR, or produce a wealth statement without one. Registration for a TIN in Bangladesh is free and, for resident Bangladeshi individuals, entirely online through NBR's e-TIN portal.

For Resident Bangladeshi Buyers

1. Register on the e-TIN portal. Resident individuals register using their National ID (NID) number, which is verified against Election Commission records through a biometric or NID-matching step. Any mismatch between the name, date of birth, or parents' names on the NID and the information entered on the portal is the most common cause of a failed application.
2. Enter income source and address details. The applicant selects an income category (salary, business, profession, capital gains, house property, etc.) and enters their present and permanent address; the system automatically assigns a Tax Circle and Zone based on the address, which the applicant should double-check for accuracy.
3. Receive the TIN certificate. Once the NID verification passes, the system generates a TIN immediately and issues a downloadable PDF certificate. This certificate is what gets presented, alongside the return acknowledgement, at the Sub-Registrar's office and to the buyer's bank.

For Non-Resident Bangladeshis (NRBs) and Foreign Nationals

NRBs and foreign nationals face an additional hurdle: NBR's online self-registration system requires a Bangladeshi NID for biometric verification, which many overseas Bangladeshis and virtually all foreign nationals do not hold in a usable form. In these cases, TIN registration must be done in person, or through an authorised representative, at the relevant Tax Circle office, supported by a passport copy, proof of a Bangladeshi address (which can be a relative's address or the address of the property being purchased, depending on the circle's practice), and any documentation showing the source of the buyer's income abroad. This step alone can take considerably longer than the near-instant online process available to residents, which is why NRB buyers are strongly advised to start TIN registration as early as possible — ideally as soon as they begin seriously negotiating a purchase, not after the deed is ready to sign.

Once the TIN is issued, the practical next step is to register on NBR's unified e-Return portal so that returns can be filed online for the relevant assessment year. Aeenx handles both the TIN registration and the e-Return account setup as a single coordinated step for clients, which avoids the delay of applicants discovering, only when they try to file, that their TIN registration details do not match what the e-Return system expects.

The documents needed fall into two groups: those required to complete TIN registration and file a return, and those required to support the wealth statement and, later, the property registration itself.

Purpose	Documents Typically Needed
TIN Registration	National ID (NID) or Smart NID; passport (for NRBs/foreign nationals); active mobile number and email; present and permanent address
Income Tax Return Filing	Salary certificate (for employees); bank statements for the income year; investment records (DPS, savings certificates, provident fund); business income records, where applicable; prior-year return acknowledgement, if any
Wealth Statement (IT-10B)	Statement of all assets and liabilities at year start and year end; the sale agreement/deed for the new house showing purchase value; bank transfer or payment records showing how the purchase was funded; details of any loan, gift, remittance, or asset sale used to fund the purchase
Property Registration Support	TIN certificate; latest return acknowledgement / PSR; NID; photographs; the executed sale deed itself, drafted separately by a deed writer or lawyer

For salaried buyers, the documentation burden is usually modest: a salary certificate, a year of bank statements, and clear evidence of any savings or investment used toward the down payment. For self-employed buyers and small business owners, the process is more involved, since business income, expenses, and any informal cash transactions need to be reconciled clearly enough that the tax officer reviewing the return (or a later audit) can see a credible link between the declared business profit and the amount spent on the house.

NRB buyers have one additional and very important document: proof of remittance through formal banking channels. Money brought into Bangladesh through a recognised bank, exchange house, or mobile financial service, and converted at the official rate, is far easier to document as a legitimate source of funds than cash carried informally or transferred through unofficial channels. An Encashment Certificate or equivalent bank confirmation showing the inward remittance and its conversion to Bangladeshi Taka is the single most useful document an NRB buyer can obtain to support their wealth statement.

It is worth noting that NBR's current e-Return system does not require documents to be uploaded at the point of filing — the return is largely self-declared online. However, all of the documents above should still be organised and retained, because they are exactly what an assessing officer will ask for if the return is selected for scrutiny, which becomes more likely, not less, in the assessment year in which a large asset like a house is acquired.

A wealth statement, filed as Form IT-10B alongside the main income tax return, is a year-end snapshot of everything a taxpayer owns and owes: cash, bank balances, investments, vehicles, land, and buildings on one side, and loans or other liabilities on the other. It is filed together with a statement of the taxpayer's expenditure for the year (Form IT-10BB) and is designed to answer one specific question: does the increase in this person's net wealth over the year make sense given the income they declared and the amount they spent on living expenses?

When a taxpayer buys a house, that purchase price must appear as a new asset in the following year's wealth statement (or the current year's, depending on the exact date of purchase relative to the assessment year). If the "accretion in wealth" — the increase in net assets from one year's closing statement to the next — is larger than the person's declared after-tax income and reasonable savings could explain, the assessing officer has grounds to question the gap. This is where a clear source-of-fund breakdown becomes essential: was the house funded from several years of accumulated salary savings, an inheritance, the sale of another property or asset, a bank loan, a gift from a family member, or remittance from abroad? Each of these has a different, legitimate documentary trail, and a well-prepared wealth statement lays that trail out clearly rather than leaving the assessing officer to guess.

This is not a punitive requirement aimed only at wrongdoing — the large majority of buyers who go through this process are simply honest taxpayers who saved up, took a home loan, or received family support, and the wealth statement is simply the formal channel for demonstrating that. The risk only arises when a buyer either has never filed a wealth statement at all, or files one that is inconsistent with the actual purchase, whether through carelessness or an attempt to under-report the true price of the property (a practice sometimes attempted through under-declaring the deed value, which creates its own separate legal exposure under stamp duty and property valuation rules).

Aeenx prepares the wealth statement as an integrated part of the annual return, cross-checking the declared purchase price against the sale agreement and the payment trail, and structuring the source-of-fund explanation so that it stands up to scrutiny if the return is selected for audit. For buyers who have never filed a wealth statement before, this is often the single most valuable part of the service, because an incorrectly prepared or omitted wealth statement is one of the most common reasons a property purchase later becomes a tax problem.

Understanding how the tax-side documentation and the deed-side registration interact helps explain why the two processes are best handled together rather than sequentially at the last minute.

1. Due diligence and agreement. The buyer verifies the seller's title through the khatian (record of rights), checks mutation history, and confirms there are no outstanding disputes or encumbrances, then signs a sale agreement (bainama) setting out price and payment terms.
2. Tax documentation prepared in parallel. While the sale agreement and any building-plan or RAJUK approvals are being verified, the buyer (if not already tax-compliant) applies for a TIN, files or updates their income tax return, and prepares the wealth statement reflecting the upcoming purchase.
3. Deed drafting. A deed writer or lawyer drafts the sale deed (often called a "saf-kabala" deed for an outright sale), reflecting the agreed price, the parties' details, and the property description.
4. Payment of stamp duty, registration fee, and other charges. Before the deed can be presented for registration, the applicable stamp duty, registration fee, local government tax, and — for flats — VAT and advance income tax must be paid through the designated bank channel.
5. Presentation at the Sub-Registrar's office. The buyer, seller, and witnesses appear before the Sub-Registrar. The registrar verifies the identity documents, the TIN certificates, and (where the transaction value requires it) the PSR of the parties, before accepting the deed.
6. Registration and collection. Once verified, the deed is registered, scanned into the government's digital record system, and the buyer collects the registered deed as legal proof of ownership.
7. Mutation. Separately, the buyer applies to update the land revenue (mutation/namjari) records so that future land tax and holding tax are assessed in the new owner's name.

The critical point for buyers to understand is that step 5 — presentation at the Sub-Registrar's office — is where a missing TIN or missing PSR causes real, on-the-day problems. A buyer who turns up without a TIN certificate, or whose TIN details do not match their NID exactly, risks having the registration rejected or delayed on the spot, after the buyer has already paid stamp duty and other charges. This is precisely the scenario the income tax return service is designed to prevent, by making sure the tax-side paperwork is in order well before the registration date is fixed.

Buying a house in Dhaka involves several separate charges collected at or around the point of registration, on top of the price paid to the seller or developer. These figures vary by mouza (the local land-valuation unit), property type, and the current NBR/stamp duty circular in force, so they should always be confirmed for the specific property before budgeting — but the components are consistent across most transactions:

Charge	Typical Basis	Approx. Rate
Stamp Duty	Higher of deed value or government-assessed (mouza) value	~1.5% (subject to a cap on the applicable non-judicial stamp portion)
Registration Fee	Deed value	~1%
Local Government Tax	Deed value	~2% (city corporation/cantonment areas), ~3% (other areas)
Advance Income Tax (AIT) at Registration	Deed value or area-based rate, depending on location	Varies significantly by location and mouza; recent reforms have raised rates in some areas
VAT (flats purchased from a developer)	Unit size	~2% for flats under 1,600 sq. ft.; ~4.5% for flats above 1,600 sq. ft.

Taken together, most published guidance suggests buyers should budget somewhere in the region of 6% to 10% of the property's registered value for combined stamp duty, registration fee, local government tax, VAT (where applicable), and the advance income tax collected at registration — separate from, and in addition to, any professional fees for legal drafting, due diligence, and the income tax return service itself. Because rates differ by mouza, property type, and whether the seller is an individual or a registered real estate company, buyers should always request a written fee estimate from the Sub-Registrar's office or their lawyer for the specific property before finalising their budget, and should treat the figures above as a planning guide rather than a quote.

It is important not to confuse the advance income tax collected at the point of registration with the buyer's own annual income tax return. The registration-stage AIT is typically a withholding-style collection tied to the transaction itself (and in many cases is a liability primarily associated with the seller's side of the transaction, though the exact incidence depends on the specific deed and local practice); the buyer's income tax return, wealth statement, and TIN are a separate, ongoing personal compliance obligation that exists independently of any single transaction. A buyer can pay every registration-stage charge in full and still fall short on the separate requirement to explain the source of the purchase price in their own tax return.

The honest, precise answer is: it depends on the value of the transaction, but in practice it is close to unavoidable for almost every meaningful house purchase in Dhaka today, and it is unambiguously required for anyone who already holds a TIN.

Under Section 264 of the Income Tax Act 2023, anyone who already has a TIN is legally required to file an income tax return every year — including a "nil return" if their income is below the taxable threshold — and failing to do so exposes them to penalties regardless of whether they are buying a house. Once a TIN exists, filing is not optional; it is an annual legal obligation tied to the TIN itself, not to any specific transaction.

For the property registration itself, whether the Sub-Registrar's office insists on seeing a TIN certificate and PSR depends on the applicable value threshold in force under NBR's current circulars and on the specific office's practice — thresholds are periodically revised through Finance Act amendments, so buyers should not rely on a fixed figure without checking the current rule. What is consistent across virtually all offices, however, is that a TIN certificate is requested as standard supporting documentation for the buyer (and often the seller) on almost every deed, regardless of value, because it has become embedded administrative practice even where the strict legal threshold might not technically require it for a smaller transaction.

Beyond the registration desk itself, the practical reality is that most house purchases in Dhaka today are financed, at least in part, through a bank loan, a developer's instalment plan, or a documented transfer of savings — and each of these channels increasingly asks for a TIN certificate as a matter of internal compliance policy. Cash-only purchases without any bank involvement are both increasingly rare and increasingly risky, since they leave the buyer with no formal documentary trail to support their wealth statement if questioned later. For all of these reasons, Aeenx's consistent advice to clients is to treat TIN registration and return filing as a standard, non-negotiable part of preparing to buy a house in Dhaka, rather than trying to determine in advance whether a specific transaction falls just above or just below a shifting legal threshold.

Buying a house without properly filed tax documentation does not, by itself, stop the sale agreement from being signed or the money from changing hands — but it creates several distinct points of exposure that tend to surface later, often at the worst possible time.

Registration delay or refusal. If the Sub-Registrar's office requests a TIN certificate or PSR that the buyer cannot produce, the registration itself can be refused or postponed on the day, after stamp duty and other charges have already been paid. Correcting this mid-process is possible but slow, since it requires obtaining the TIN and filing a return from scratch while the transaction is effectively on hold.

An "unexplained investment" tax notice. If the house eventually does appear in the buyer's records — for example because a later return references it, or because a bank loan tied to the property is reported to NBR — but no wealth statement was ever filed showing its source of funds, the assessing officer can treat the acquisition as unexplained. This can lead to the value of the property (or the unexplained portion of it) being added to the buyer's taxable income for the relevant year, together with the tax due on that amount and, in more serious cases, a penalty.

Complications when reselling. A property bought without clean tax documentation on the buyer's side can create difficulties years later when that buyer becomes a seller, since a new buyer's own lawyer or bank may ask questions about the original purchase's tax history as part of their due diligence.

Loss of access to other PSR-gated services. Because Section 264 ties PSR to a wide range of other services — loans, director appointments, licence renewals — a person who has never regularised their tax position because of a single missed property purchase can find that gap following them into unrelated financial dealings later.

None of these outcomes are inevitable, and none of them are difficult to avoid with proper planning. The overwhelming majority resolve cleanly once a TIN is registered and a return with an accurate wealth statement is filed — even if that happens somewhat later than ideal. The point of raising them here is simply that the cost of prevention (a properly filed return before the purchase) is small and predictable, while the cost of a late correction, an audit, or a stalled registration is neither.

It is important to separate what the government charges (which are fixed or free) from what a consultancy or law firm charges for professional assistance (which varies by provider and by the complexity of the client's income sources).

There is no NBR government fee for TIN registration, for filing an income tax return, or for submitting a wealth statement — these are free services provided directly by the tax authority through its online portals. What buyers actually pay for, when they engage a firm like Aeenx, is professional time: reviewing the buyer's income sources, preparing an accurate and defensible return and wealth statement, reconciling the purchase price and payment trail against declared income, filing any missed prior-year returns where relevant, and liaising with the buyer's registration lawyer so the tax documentation and the deed timeline line up.

For a straightforward salaried buyer with a clean, well-documented source of funds and no missed prior-year filings, the professional fee for this service is typically modest, since the work involved is mostly organisation and filing. For a self-employed buyer or business owner whose income needs more careful reconciliation, for an NRB buyer who needs in-person TIN registration and remittance documentation reviewed, or for anyone catching up on several years of missed returns before a purchase, the fee is correspondingly higher, reflecting the additional professional judgment required to prepare a return and wealth statement that will hold up under scrutiny. Because these fees depend heavily on individual circumstances, Aeenx provides a specific written quote after an initial review of the buyer's situation rather than a single fixed headline price, and we encourage buyers to be similarly cautious of any provider quoting a flat fee before reviewing the underlying income and asset picture.

The timeline depends heavily on whether the buyer is starting from zero (no TIN, no prior returns) or simply needs a current-year return and wealth statement updated ahead of a purchase.

For a Resident Buyer With No Existing TIN

1. TIN registration (same day to 2 working days): Online registration is typically instant once NID verification passes; occasional delays occur if the NID details do not match Election Commission records exactly.
2. Return preparation and filing (3 to 10 working days): Gathering salary certificates, bank statements, and investment records, then preparing and filing the return along with the wealth statement.
3. PSR issuance (immediate on filing): The system-generated PSR certificate is available for download as soon as the return is successfully submitted.

For a Buyer Catching Up on Missed Prior-Year Returns

Where a buyer already had a TIN but has not filed for one or more prior years, those returns generally need to be filed (or regularised with the relevant Tax Circle) before or alongside the current year's return, which can extend the overall timeline to 2 to 6 weeks, depending on how many years are outstanding and how complex the buyer's income sources are.

For NRB and Foreign National Buyers

Because TIN registration cannot be completed online and instead requires an in-person or representative-filed application at a Tax Circle office, this step alone commonly takes 1 to 3 weeks, and the full process including return filing and wealth statement preparation typically spans 3 to 6 weeks. NRB buyers who know they intend to purchase property in Dhaka should begin this process as soon as serious negotiations start, well before a specific registration date is fixed with the seller.

Separately, the property registration itself — deed drafting, payment of stamp duty and other charges, and the Sub-Registrar appointment — typically runs on its own timeline of a few days to a few weeks depending on document readiness and the Sub-Registrar office's workload. Where possible, Aeenx coordinates the tax-side timeline and the registration-side timeline so that the buyer's TIN, return, and wealth statement are already finalised well before the deed is presented for registration, removing the single most common cause of last-minute delay.

Beyond simple compliance, a properly filed return and wealth statement give a house buyer several concrete, practical advantages that go well past avoiding a penalty.

• Smoother registration. A buyer who arrives at the Sub-Registrar's office with a TIN certificate and PSR already in hand avoids the single most common cause of on-the-day registration delay.
• Protection from future tax notices. A wealth statement that clearly reconciles the purchase against declared income closes off the most common route by which a property purchase turns into an unexplained-investment assessment years later.
• Stronger position when applying for a home loan. Banks assessing a mortgage application look favourably on a documented, consistent income and tax history, since it supports both the loan approval and the interest rate offered.
• A clean paper trail for resale. When the buyer eventually becomes a seller, a documented purchase history makes due diligence for the next transaction faster and less contentious.
• Eligibility for other PSR-gated services. Because the same TIN and PSR unlock other regulated services under Section 264 — loans, directorships, licence renewals — regularising tax status for a house purchase has knock-on benefits for the buyer's broader financial life.
• Peace of mind for the family. For many Bangladeshi households, a house is the single largest asset the family will ever hold; having its ownership and tax history properly documented protects the interests of a spouse, children, or other heirs who may need to rely on that documentation in the future, including in inheritance matters.

Taken together, these benefits explain why Aeenx treats the income tax return service not as a bureaucratic afterthought bolted onto a property purchase, but as a core piece of the overall transaction — one that protects the value of the asset the buyer is acquiring just as much as the legal due diligence on the title itself.

Aeenx's team sees the same handful of avoidable mistakes recur across most first-time and NRB buyers. Recognising them in advance is the easiest way to avoid delay and expense.

• Leaving TIN registration until the deed is ready. Buyers frequently assume TIN registration is a same-day formality and only start it once the registration date is already fixed with the seller. For NRBs in particular, this can mean the tax paperwork is the reason the whole transaction is delayed.
• Under-declaring the deed value. Some buyers and sellers agree, informally, to record a lower price on the deed than what actually changed hands, in order to reduce stamp duty and registration fee. This is illegal, creates a mismatch between the declared purchase price and the actual funds transferred, and directly undermines the buyer's own wealth statement, since the true source-of-fund trail will not match the artificially low declared value.
• Ignoring the wealth statement entirely. Many taxpayers file an income return every year but skip the wealth statement, either because they were never told it applied to them or because they assume it is optional. Once a large asset like a house enters the picture, this omission is exactly the gap that later triggers an unexplained-investment inquiry.
• Mixing personal and business funds without a clear record. Self-employed buyers who pay for a house partly from business accounts and partly from personal savings, without keeping the two streams separately documented, make it much harder to prepare a wealth statement that clearly traces the source of funds.
• Assuming a cash purchase avoids the issue. A cash-financed purchase does not exempt the buyer from the requirement to explain the source of funds; it simply removes the bank's own paper trail, which usually makes it harder, not easier, to satisfy an assessing officer later.
• Not checking the current PSR threshold. Because thresholds and rules shift with each Finance Act, buyers sometimes rely on outdated information about whether a transaction of their size requires a PSR at all. The safest approach is always to confirm the current requirement rather than assume last year's rule still applies.

Each of these mistakes is straightforward to avoid with early planning, which is the main reason Aeenx recommends starting the income tax return service as soon as a buyer begins seriously negotiating a purchase, rather than waiting until the deed is ready for signature.

At Aeenx, we support house buyers in Dhaka through the full tax-compliance side of a property purchase: TIN registration for both resident and non-resident buyers, current and prior-year income tax return filing, wealth statement (IT-10B) preparation reconciling the purchase against declared income, and direct coordination with the buyer's registration lawyer or deed writer so the tax documentation is ready well before the Sub-Registrar appointment. We also assist NRB clients with the additional steps around remittance documentation and in-person TIN registration where the online system is not available to them.

Our approach is to review each buyer's specific income sources and purchase structure first, then map out exactly which documents are needed and what timeline is realistic — rather than applying a one-size-fits-all checklist to every client. Whether you are a first-time buyer with a straightforward salary income, a business owner with more complex income streams, or an NRB purchasing a flat from abroad, we tailor the return and wealth statement work to your actual situation.

Frequently Asked Questions

Do I need a TIN to buy a flat in Dhaka?

Most Sub-Registrar's offices request a TIN certificate as standard supporting documentation for the buyer before accepting a sale deed for registration, and if you already hold a TIN you are legally required to file a return every year regardless of the purchase. It is best to register for a TIN before you begin the registration process, even if your specific transaction value might fall under any applicable threshold.

What is a Proof of Submission of Return (PSR)?

A PSR is documentary evidence, under Section 264 of the Income Tax Act 2023, that a taxpayer has filed their income tax return for the relevant assessment year. It can be a filing acknowledgement, a system-generated certificate from the e-Return portal, or a certificate from a Deputy Commissioner of Taxes, and it is required before certain regulated services and transactions can be processed.

Can I register a house without filing an income tax return?

If you have never registered for a TIN and your transaction falls below the applicable value threshold, some registrations may proceed without a PSR, but in practice most Sub-Registrar offices still ask for a TIN certificate as standard practice. If you already hold a TIN, you are legally required to file a return regardless of the transaction.

What is a wealth statement and do I need one?

A wealth statement (Form IT-10B) is a year-end summary of your assets and liabilities filed alongside your income tax return. It is required for taxpayers whose income or asset profile meets NBR's specified conditions, and it is the document that reconciles a new house purchase against your declared income, protecting you from a later unexplained-investment tax notice.

How long does TIN registration take before buying a house?

For resident Bangladeshi buyers, online TIN registration is typically instant once NID verification passes. For NRBs and foreign nationals, who cannot use the online self-registration system, in-person registration at a Tax Circle office commonly takes one to three weeks.

How much does an income tax return service for buying a house cost?

NBR charges no government fee for TIN registration, return filing, or wealth statement submission. Professional service fees from a firm like Aeenx vary depending on the complexity of your income sources, whether prior-year returns need to be filed, and whether you are a resident or an NRB buyer, so a specific quote is provided after an initial review.

What happens if the source of funds for my house purchase is questioned?

If NBR questions the source of funds for a property, the buyer needs to demonstrate, through bank records, salary history, remittance certificates, loan documents, or other evidence, how the purchase was funded. If no credible source can be shown, the unexplained portion of the property's value can be treated as undisclosed income and assessed for tax, and potentially penalty.

Do NRBs need a TIN to buy property in Bangladesh?

Yes. NRBs face the same TIN, PSR, and wealth statement requirements as resident buyers, but must complete TIN registration in person or through an authorised representative at a Tax Circle office, since NBR's online self-registration system requires a Bangladeshi NID for biometric verification.

Is stamp duty the same as income tax when buying a house?

No. Stamp duty, registration fee, local government tax, and VAT (for flats) are charges collected at the point of property registration under separate laws, primarily the Registration Act, 1908 and related stamp duty rules. The buyer's income tax return, TIN, and wealth statement are a separate, ongoing personal compliance obligation under the Income Tax Act 2023, independent of the specific transaction charges.

Can I file my income tax return myself instead of using a service?

Yes, NBR's e-Return system is designed for self-filing and charges no fee. Many salaried taxpayers with straightforward income file their own returns. A professional service becomes more valuable when income sources are complex, prior-year returns are missing, or a wealth statement needs to be prepared carefully to withstand later scrutiny.

What documents prove the source of funds for a house purchase?

Common evidence includes bank statements showing accumulated savings, salary certificates, remittance or Encashment Certificates for funds sent from abroad, loan sanction letters and disbursement records, gift declarations from family members, or sale documents if the funds came from selling another asset.
