How to Calculate Income Tax (Step-by-Step)

• Step 1: Compute annual taxable income from salary, bonus, business, rent, and other taxable sources.
• Step 2: Apply the correct slab structure based on selected filing year.
• Step 3: Apply eligible investment rebate.
• Step 4: Apply minimum tax rules if tax after rebate is below minimum threshold.
• Step 5: Apply surcharge if net-asset criteria are met.
• Step 6: Subtract advance tax/TDS to estimate final payable or refund.

Worked Example

• Example annual income: BDT 1,000,000.
• Using 2026-27 onward announced structure: first 375,000 at 0%, next 300,000 at 10%, remaining 325,000 at 15%.
• Tax = 30,000 + 48,750 = BDT 78,750 (before rebate/minimum tax/surcharge adjustments).
• Actual filing output can differ once taxpayer category, rebate, minimum tax, and surcharge are applied.

Rebate Rule (Investment)

• Rebate is calculated as the minimum of these limits.
• 3% of total income.
• 15% of eligible investment.
• Absolute ceiling: BDT 1,000,000.
• Rebate cannot exceed gross tax liability.

• 2026-27 onward announced minimum tax: generally BDT 5,000 and BDT 1,000 for new taxpayers.
• Surcharge applies for higher net-asset taxpayers and certain asset ownership conditions.
• Tax return filing is generally required when income crosses threshold, or for practical needs like bank loan, trade license, visa, and similar compliance use-cases.

Corporate Tax and VAT (Quick Overview)

• Corporate rates vary by entity type and sector; use current NBR finance-act schedule for exact rate.
• Public and private company rates differ, and banking/NBFI rates are higher than many other sectors.
