Tax Summary
How to Use This Bangladesh Income Tax Calculator
Enter your annual taxable income in Taka (BDT) and select your taxpayer category. Add any eligible investments to calculate your 15% investment rebate. The calculator applies the correct minimum tax and shows your final tax payable.
This calculator covers the NBR (National Board of Revenue) 2025-26 income year assessment. The tax-free threshold is BDT 350,000 for general male taxpayers and BDT 400,000 for female taxpayers and senior citizens aged 65 or older.
The Formula
Rebate Base = min(Investments, 25% of taxable income, 10,00,000 BDT)
Investment Rebate = Rebate Base × 15%
Net Tax = max(Slab Tax − Investment Rebate, Minimum Tax)
Minimum Tax: ৳5,000 (Dhaka/CTG) or ৳4,000 (others)
Example
Tax-free: ৳3,50,000 @ 0% = ৳0
Next ৳1,00,000 @ 5% = ৳5,000
Next ৳3,00,000 @ 10% = ৳30,000
Gross tax: ৳35,000
Rebate base: min(1,00,000; 25% of 8,00,000=2,00,000) = ৳1,00,000
Investment rebate: ৳1,00,000 × 15% = ৳15,000
Net tax: ৳35,000 − ৳15,000 = ৳20,000
(Above minimum ৳5,000 ✓)
