In Bangladesh, you need to gather the necessary documents to file a tax return and ensure compliance with the National Board of Revenue (NBR). Here, proper documentation supports accurate reporting of income and deductions.
You can keep complete records to claim all eligible exemptions and tax rebates with its assistance. Moreover, timely and well-prepared document submissions reduce the risk of penalties or delays in return processing.
What Is an Income Tax Return?
An income tax return is a formal statement you submit to the NBR to report details of your annual income, allowable expenses, deductions, tax due, or refund. You must file a return if your taxable income exceeds the tax-free threshold or if the NBR has issued an assessment for any of the previous three years.
Some people need to file a tax return regardless of their income. They include directors, partners, executives, and those with exempt or reduced-rate income. In Bangladesh, you are required to file a tax return within the dates set by the NBR. Recently, the NBR made online e-filing mandatory for most taxpayers with limited exemptions.
What Documents Are Required for Income Tax Return Submission?

What Is the Minimum Tax Amount in Bangladesh?
In Bangladesh, income tax follows a slab system, where different parts of your annual income are taxed at increasing rates. For instance, for FY 2025/26 and 2026/27, the tax slab is the following.
| Total income (BDT) | Tax rate (%) |
|---|---|
| First 375,000 | Nil |
| Next 300,000 | 10 |
| Next 400,000 | 15 |
| Next 500,000 | 20 |
| Next 2 million | 25 |
| On rest of the income | 35 |
Even if your slab-based tax is low, a minimum tax applies depending on your area. For assessment year 2025-26, it is Tk 5,000 for Dhaka/Chattogram city corporations, Tk 4,000 for other city corporations, and Tk 3,000 outside city corporations.
However, according to the new proposal, the minimum tax will be BDT 5,000 in AY 2026- 27 in all locations. The minimum amount of tax for new taxpayers will be BDT 1,000. For individuals earning from business, profession, or trade, an additional rule applies if their gross receipts exceed BDT 40 million.
