Estimates, not advice

TaxHisab's calculators produce estimates for planning, computed from the published law as recorded on the methodology page. They are general information, not tax advice for your circumstances. Tax law changes — most years at the June budget — and individual cases carry facts no calculator asks about. For a return with business rules, special-rate income, or an assessment in dispute, use a qualified tax practitioner.

Not the NBR; nothing is filed

TaxHisab is not the National Board of Revenue (NBR), is not affiliated with or endorsed by it, and does not file, submit, or register anything with any authority. Tax returns are filed on the official e-Return portal, etaxnbr.gov.bd. No result from this site is a filed return, an assessment, or evidence of either.

Accuracy and its limits

Every figure is verified against the sources named on each page, with the verification date printed there, and the calculators are tested against hand-worked examples. Even so: where the site's figure and the official text disagree, the official text governs. Items labelled guidance (such as per-instrument rebate counting limits reported from the NBR's Income Tax Guide) are presented as guidance, not as the assessed rule, and items flagged as estimates (such as capital gains at slab rates) are approximations by design.

Your figures stay yours

As the privacy page states, nothing typed into a calculator leaves your browser. You are responsible for the accuracy of what you type; a result is only ever as good as its inputs and the rules in force for the year selected.

Use of the site

The calculators and content are provided free for personal and professional estimation. The worked examples, tables and guides may be quoted with a link back to the page they came from. The site is provided as-is; to the extent the law allows, AH Digital Studio is not liable for a decision taken on an estimate that the official text contradicts.
