Frequently asked questions

No. TaxHisab is an independent tool with no connection to the National Board of Revenue (NBR) or any government body. Calculating here does not file a return. Returns are filed on the NBR's etaxnbr.gov.bd.

The rates, tax-free thresholds, investment rebate and minimum tax for assessment year 2026-27 come from the NBR's Income Tax Guidelines 2026-27, and the worked examples in those guidelines match our calculator to the taka. It is still an estimate: the result depends on what you enter, and rental and agricultural income are worked out by the rules in the guidelines, but some matters (such as surcharge, business expenses and capital gains) are not modelled. See the disclaimer.

No. The Quick and Detailed calculators and the PDF download are free, and no account, name, phone number or TIN is needed.

Yes. The figures and the result are kept under a random calculation id for 90 days, so you can reopen the result page and the PDF; after that they are deleted automatically. No name or other identity is stored with them. See the privacy policy.

Use the Quick calculator if your income is a private-sector salary and you want a fast idea. Use the Detailed calculator if you have rent, farm or business income, an investment tax rebate, advance tax, or the extra tax-free allowance for a disabled child. Both use the same rules.

৳4,00,000 for a general taxpayer. ৳4,50,000 for women and for taxpayers aged 65 or over; ৳5,25,000 for third-gender and disabled taxpayers; ৳5,50,000 for gazetted war-wounded freedom fighters and gazetted injured July fighters. Parents or guardians of a disabled child or dependant get a further ৳50,000 per child or dependant. Details: tax rates and thresholds.

৳3,75,000 was announced earlier for 2026-27. The Finance Act 2026 then changed it; under the NBR's Income Tax Guidelines 2026-27 the general threshold is ৳4,00,000, and every example in the guidelines uses that figure.

If your income is above the tax-free threshold, at least ৳5,000 is payable even when the calculated tax, or the tax after rebate, is lower or zero. For a first-time taxpayer the minimum is ৳1,000. The amount is the same wherever in Bangladesh you live; the old area-based amounts no longer apply.

The lowest of three amounts: 3% of total income, 10% of eligible investments and donations, or ৳7,50,000. Worked examples: investment tax rebate.

No. For private-sector employees, one third of total salary receipts or ৳5,00,000, whichever is lower, is exempt; the calculator deducts this itself, so enter your gross salary. For employees on the government pay scale only basic pay, festival allowance and bonus are taxable, and the one-third exemption does not apply to them; choose "government" under employment type and enter basic pay and festival allowance only.

Monthly salary is multiplied by 12 to give annual income. Enter festival bonuses or other yearly receipts in their own fields in the Detailed calculator. If your salary changed during the year, enter the average monthly amount.

When tax deducted at source and advance tax exceed your liability, tax payable is shown as ৳0 and the excess is shown separately. The law allows a refund claim or an adjustment against the next year, but that is decided by the tax authority after you file your return. We therefore do not present it as a guaranteed refund.

That is the minimum tax. Once income passes the tax-free threshold, ৳5,000 is payable even if the calculated tax or the tax after rebate is lower (৳1,000 for a first-time taxpayer). The result page shows it on its own "Minimum Tax" line.

No. The PDF is for checking and keeping your own estimate. It is not an NBR document and is not proof of filing.

For 2026-27, filing between 1 July and 30 September earns a tax incentive of 5% of tax payable or ৳25,000, whichever is lower. There is no additional tax until 31 December; filing after that attracts additional tax. Details: filing a return for 2026-27. The calculator does not include this incentive or additional tax.
