Bangladesh Income Tax Calculator
Estimate your personal income tax for FY 2026-27 (AY 2027-28) under the NBR progressive slab system. 100% private — your salary never leaves your browser.
Your Salary
Enter your gross monthly salary. Annual income = monthly × 12.
How this is calculated
Your annual income of ৳1,200,000 is taxed progressively — each bracket is taxed only on the slice of income inside it. The first ৳375,000 is tax-free.
- • ৳300,000 taxed at 10% = ৳30,000
- • ৳400,000 taxed at 15% = ৳60,000
- • ৳125,000 taxed at 20% = ৳25,000
Total tax: ৳115,000. Your effective rate (9.58%) is lower than your marginal rate (20%) because most of your income is taxed in the lower brackets.
Estimate based on proposed FY 2026-27 slabs. Confirm with official NBR rates before filing.

What is a Bangladesh Income Tax Calculator?
A Bangladesh income tax calculator helps you estimate the personal income tax you owe to the National Board of Revenue (NBR) for a given fiscal year. Our 2026 calculator uses the progressive slab system: your income is split into brackets, and each bracket is taxed at its own rate, so you only pay higher rates on the portion of income that falls in the higher brackets. Enter your monthly salary to instantly see your annual income, tax-free allowance, taxable income, total tax, monthly tax estimate, effective rate, and a full bracket-by-bracket breakdown. You can also choose your taxpayer category (general, woman, senior citizen, person with disability, or freedom fighter) and add eligible investments like life insurance, DPS, and provident fund to claim your tax rebate. Every calculation runs entirely in your browser — your salary is never uploaded.

- The calculator multiplies it by 12 to get your annual income automatically.

Frequently Asked Questions
Which fiscal year does this calculator use?
It uses the FY 2026-27 (Assessment Year 2027-28) progressive slabs. Always confirm current rates with NBR before filing.
What is the difference between effective and marginal tax rate?
Your marginal rate is the rate on your highest bracket. Your effective rate is total tax divided by total income, and is always lower because most income is taxed in lower brackets.
Is my salary uploaded anywhere?
No. Every calculation runs entirely in your browser. Nothing is sent to a server.
How is the investment rebate calculated?
The rebate applies to the lower of your eligible investments or 20% of taxable income, at your average tax rate, capped at your total tax.
Why does my taxpayer category matter?
Women, senior citizens, persons with disability, and freedom fighters receive a higher tax-free floor, which lowers their total tax.
Does this include surcharge or minimum tax?
No. This is an income-tax estimate on salary. Surcharge, minimum tax, and other levies are not included.
Can I use this for business income?
It is designed for personal/salary income. Business income has different rules — consult a tax professional.
Are the exemption amounts official?
They are proposed defaults for FY 2026-27. Verify the exact thresholds against official NBR publications before filing.
