Finance Adviser Salehuddin Ahmed proposed in June 2025, the tax-free income threshold of male taxpayers from Tk. 3 lakh 50 thousand will be unchanged in the next fiscal year.
As part of the proposed measures, the tax-free income threshold for individual taxpayers has been increased from Tk 3.5 lakh to Tk 3.75 lakh for the assessment years 2026–27 and 2027–28. In addition, taxpayers officially recognised as “July Warriors”—those injured during the July 2024 mass uprising—will benefit from a higher tax-free income limit of Tk 5.25 lakh.
Income in the next slab of Tk 100,000 will be taxed at 5%, followed by 10% on the next Tk 400,000. The subsequent Tk 500,000 will be taxed at 15%, the next Tk 500,000 at 20%, and the following Tk 2 million at 25%. Under the newly proposed income slabs, any income exceeding Tk 3.85 million will be subject to a 30% tax rate.

Income Tax Calculation Example in Bangladesh 2026-2027
To do an income tax calculation example in Bangladesh, we need the first eTIN certificate and income tax return form bd. If you need eTIN certificate click here.
Step 1: Calculate Your Total Gross Salary
First, sum up every component of your salary received during the fiscal year (July–June). This includes:
- Basic Salary
- House Rent Allowance
- Medical Allowance
- Conveyance Allowance
- Festival Bonuses
- Any other allowances (Performance bonus, Leave Encashment, etc.)
Step 2: Subtract the “Standard Exemption”
Previously, house rent, medical, and conveyance had separate tax-free limits. Now, under the simplified rule, you apply a single exemption to your total gross salary.
The Exemption Amount is the LOWER of:
- One-third (33.33%) of your total gross salary, OR
- BDT 4,50,000 (This limit was proposed to increase to BDT 5,00,000 in recent budget discussions; check your latest salary certificate for the exact cap applied by your employer).
Formula: $Taxable Salary = Gross Salary – Exemption$
Step 3: Identify Your Tax-Free Threshold
Not everyone starts paying tax from the same amount. Your “tax-free limit” depends on your status:
| Category | Tax-Free Threshold (Annual) |
| General Taxpayers (Male) | BDT 3,75,000 |
| Women & Senior Citizens (65+ years) | BDT 4,25,000 |
| Physically Challenged / Third Gender | BDT 5,00,000 |
| Gazetted War-Wounded Freedom Fighters | BDT 5,25,000 |
Step 4: Apply the Progressive Tax Slabs
Once you subtract the threshold from your taxable income, the remaining amount is taxed in “layers.” For FY 2025–26, the slabs are:
| Taxable Income Slab | Tax Rate |
| On the first BDT 375,000 | 0% |
| On the next BDT 300,000 | 10% |
| On the next BDT 400,000 | 15% |
| On the next BDT 500,000 | 20% |
| On the next BDT 2,000,000 | 25% |
| On the Remaining Balance | 30% |
Step 5: Calculate Investment Rebate
You can reduce your total tax by investing in approved sectors (e.g., DPS, Savings Certificates/Sanchayapatra, Life Insurance, or Listed Stocks).
The Tax Rebate is the LOWER of:
- 3% of your Total Taxable Income.
- 15% of your Actual Investment.
- BDT 1,000,000 (Fixed Cap).
Subtract this rebate from your total calculated tax to find your Net Tax Payable.
Step 6: Check for Minimum Tax
If your total income exceeds the tax-free limit, you must pay a minimum tax regardless of your rebate.
- Flat Rate: BDT 5,000 (standard for most city corporation areas).
- New Taxpayers: Often eligible for a reduced minimum of BDT 1,000 in their first year.
Example Calculation
Imagine a male employee with a gross annual salary of BDT 1,200,000.
- Gross Salary: BDT 1,200,000
- Exemption: One-third of 1,200,000 = BDT 400,000 (which is less than the 4.5L/5L cap).
- Taxable Income: 1,200,000 – 400,000 = BDT 800,000.
- Tax Breakdown:
- First 375,000 @ 0% = 0
- Next 300,000 @ 10% = 30,000
- Remaining 125,000 @ 15% = 18,750
- Total Tax: BDT 48,750.
- Rebate: If he invests enough, he can claim 3% of 800,000 (BDT 24,000) as a rebate.
- Net Tax: 48,750 – 24,000 = BDT 24,750.
