Minimum Tax ৳5,000: Who Pays It, and When ৳1,000 Applies Instead
The minimum tax (ন্যূনতম কর) is the floor under the whole slab system: once your total income passes your tax-free limit, you pay at least this much — even if the slabs, or the slabs after your rebate, say less.
The rule, on the current card
| Situation | Minimum tax |
|---|---|
| Total income at or below your tax-free limit | None — the minimum tax does not apply |
| Total income above the limit, ordinary return | ৳5,000 — flat, anywhere in Bangladesh |
| Total income above the limit, first return | ৳1,000 |
Two changes are recent and widely missed. Location no longer matters: until last year the minimum was ৳5,000 in Dhaka and Chattogram city corporations, ৳4,000 in other city corporations and ৳3,000 elsewhere; the Finance Act 2026 flattened it to ৳5,000 nationwide. The floor survives the rebate: the NBR's position, stated in its Income Tax Paripatra, is that even if the tax after the investment rebate falls to zero, the minimum tax is still payable once income is above the limit.
Worked example — the floor in action
A general taxpayer with total income of ৳4,20,000: only ৳20,000 sits above the ৳4,00,000 limit, at 10% — slab tax ৳2,000. Payable: ৳5,000, because the minimum tax replaces the smaller figure. The same person filing for the first time pays ৳1,000: the first-return concession replaces the computed tax inside this minimum-tax zone (this exact example is the one the NBR's retained benefit was reported with). Once the computed tax rises above ৳5,000 — at a total income of ৳4,50,001 for a general taxpayer — the concession makes no difference and the slabs rule alone.
Who this catches out
Most often, people just above the limit: a small raise, a bonus, or a little freelance income can move a return from “no tax” to the full ৳5,000 floor, because the floor is a cliff, not a slope. It also catches people who invest heavily expecting a zero bill: the rebate can erase the slab tax, but the floor remains. Both behaviours are reproduced exactly in the income tax calculator — enter 420000 of other income and watch the minimum-tax line appear.
Minimum tax questions
My income is only just above the limit. Do I really pay ৳5,000?
Yes, if this is not your first return. Total income of ৳4,20,000 produces slab tax of only ৳2,000 — but the minimum tax lifts the payable to ৳5,000. On a first return, ৳1,000 is payable instead: the concession replaces the computed tax inside this zone, which is the NBR’s stated example, not a rounding choice.
Does the minimum tax apply if my employer already deducted more?
The minimum tax is about the total tax payable, not about how it was paid. If your TDS already exceeds the minimum — or exceeds your full calculated tax — the excess is credited; whether it is refunded or adjusted is decided on assessment.
