Bangladesh Income Tax Calculator
The whole calculation, in the order the law does it: the salary exemption first, then the slabs, then the investment rebate against all three of its limits, then the minimum-tax floor, the wealth surcharge, and credit for tax you already paid. Every figure carries its Finance Act source.
Quick check: on a total income of ৳10,00,000, a general taxpayer owes ৳75,000 on the current card — and owed ৳67,500 on last year's. If another calculator gives you a third number for the same income, it is running the proposed ৳3,75,000 limit that was never enacted. Why the numbers differ →

Rates: Finance Act 2026 — the same rates are fixed for both current assessment years.
The parent allowance does not stack on the freedom-fighter limit — a gazetted freedom fighter uses the freedom-fighter limit, and the parent allowance belongs to the parent's own return.
A worked example, by hand
A salaried taxpayer (general category) earns ৳18,00,000 in the year. Step 1 — the salary exemption: one third of ৳18,00,000 is ৳6,00,000, but the cap is ৳5,00,000, so ৳5,00,000 comes off and total income is ৳13,00,000. Step 2 — the slabs: the first ৳4,00,000 is tax-free; the next ৳3,00,000 at 10% is ৳30,000; the next ৳4,00,000 at 15% is ৳60,000; the remaining ৳2,00,000 at 20% is ৳40,000. Tax: ৳1,30,000. Enter 1800000 as salary above and the calculator must land on exactly this — it is one of the worked tests the calculation is checked against before any figure is published.
Try a second one: total income ৳20,00,000 with ৳8,00,000 invested. Slab tax is ৳2,90,000. The rebate limits are 3% of income = ৳60,000, 10% of investment = ৳80,000, and the ceiling ৳7,50,000 — the lowest is ৳60,000, so the tax is ৳2,30,000, and the binding limit is the income limit: investing more would not have saved another taka.
Income tax questions
Which income year should I pick?
The year the income was earned. Income earned from 1 July 2025 to 30 June 2026 is income year 2025-26, filed in assessment year 2026-27 — that is the return now being filed. Income you are earning now (from 1 July 2026) is income year 2026-27, assessed in 2027-28 on exactly the same rates, because the Finance Act 2026 fixed both years identically. The 2024-25 option is last year’s card, for late filers and comparisons.
Why does my result show three rebate figures?
Because the law sets the rebate as the lowest of three: 3% of your total income, 10% of your eligible investment (15% last year), and a ceiling of ৳7,50,000 (৳10,00,000 last year). The highlighted row is the one that actually limits you. Most calculators quietly apply one formula and never show you the other two.
My tax came out below ৳5,000 but the calculator charges ৳5,000. Why?
The minimum tax. Once your total income passes your tax-free limit, you pay at least ৳5,000 wherever you live — or ৳1,000 on a first return, where the ৳1,000 replaces the computed tax inside that zone. Below or at the limit, no minimum tax applies at all.
I already paid tax at source (TDS). Is it counted?
Yes — enter it in the “tax already paid” field and it is credited against the tax payable. If you paid more than the tax due, the result says so; whether the excess is refunded or adjusted is decided on assessment, and this page does not promise a refund.
