About TaxHisab

TaxHisab is run by Abdul Hannan (AH Digital Studio). It exists because of a specific, fixable problem: for the return now being filed in Bangladesh, three different tax-free limits were circulating — last year's figure, a proposed figure that was never enacted, and the enacted one — and most calculators would not tell you which of the three they were using, or where any of their numbers came from.

What this site is

• A set of free calculators for individual income tax in Bangladesh: the full calculation, salary tax, the investment rebate, the tax-free limit, and the wealth surcharge.
• A figure register. Every rate, threshold and limit is listed on the methodology page with the Act it comes from and the date it was verified, and each calculator's arithmetic is checked against worked examples computed by hand before the figures are republished.
• Private by construction. The calculators run entirely in your browser. There are no accounts, and nothing you type is uploaded or stored.

What this site is not

• Not the National Board of Revenue, not affiliated with it, and not a filing service. Returns are filed on the official e-Return portal, etaxnbr.gov.bd.
• Not tax advice. The results are estimates for planning, built from the published law; a complicated return — business income with its own rules, capital gains with special rates, a disputed assessment — deserves a qualified tax practitioner.
• Not a promise. Where a figure could not be verified to the standard the site sets itself, it is labelled guidance or left out, and the methodology page says which is which.

Corrections

Tax law changes every June with the Finance Act, and occasionally between budgets. If you find a figure here that disagrees with the official text, the official text wins — report it and it will be corrected at the top of the queue, with the correction reflected in the verified date on every page that uses the figure.
