Income Tax Calculation in Bangladesh: A Complete Guide for 2024–25
What Is Income Tax Calculation in Bangladesh?
Income tax calculation in Bangladesh is the process of determining the amount of tax a resident individual, non-resident, or corporate entity is legally obligated to pay to the National Board of Revenue (NBR) based on their total taxable income in a given income year (July 1 – June 30).
Governed by the Income Tax Act 2023 (which replaced the Income Tax Ordinance 1984), the framework defines how income is categorised, what deductions are permissible, and how the applicable tax rate is applied to arrive at your final tax liability.
For most taxpayers in Bangladesh — whether a salaried employee, business owner, freelancer, or company director — understanding income tax calculation is not merely a compliance requirement. It is a vital financial planning tool. Errors or omissions in your return can lead to penalties, interest charges, or even legal proceedings by the NBR.
At SAM & Associates, we have been helping individuals and businesses navigate Bangladesh’s tax landscape since 2013. This guide provides a comprehensive, up-to-date breakdown of income tax calculation in Bangladesh to help you stay compliant and tax-efficient.
Why Income Tax Calculation in Bangladesh Is Important
Understanding your income tax obligations matters for several reasons:
Legal Compliance: Filing an accurate return by the November 30 deadline is mandatory for all registered taxpayers holding a Tax Identification Number (TIN). Late or incorrect filing attracts penalties under Section 174 of the Income Tax Act 2023.
Financial Planning: Knowing your tax liability in advance allows you to plan investments, claim eligible deductions, and minimise your effective tax rate legally.
Business Credibility: For companies and entrepreneurs, up-to-date tax compliance is often a prerequisite for bank loans, government tenders, import/export licences, and trade body memberships.
Avoiding Double Taxation: Bangladesh has Double Taxation Avoidance Agreements (DTAAs) with over 30 countries. Accurate calculation helps non-residents and expatriates avoid being taxed twice on the same income.
Whether you are a first-time filer or a seasoned business owner, professional guidance from SAM & Associates’ Tax Consultancy team can make the process far more manageable.
Who Must Pay Income Tax in Bangladesh?
Under the Income Tax Act 2023, the following categories of persons are required to file income tax returns if their income exceeds the tax-free threshold:
- Resident individuals (including salaried employees, self-employed professionals, and business owners)
- Non-resident Bangladeshis (NRBs) earning income from Bangladesh sources
- Companies registered in Bangladesh (public and private limited)
- Partnership firms
- Trusts, funds, and associations
- Foreign companies with a permanent establishment in Bangladesh
Tax Residency in Bangladesh
An individual is considered a tax resident if they stay in Bangladesh for 182 days or more in an income year, or 90 days in the current year having stayed at least 365 days in the preceding four years. Residents are taxed on global income; non-residents are taxed only on Bangladesh-sourced income.
Income Tax Slabs and Rates in Bangladesh (FY 2024–25)
The NBR revises income tax slabs periodically through the Finance Act. The following rates apply for individual resident taxpayers for the income year 2024–25 (assessment year 2025–26):
Individual Tax Slabs (General)
| Income Bracket (BDT) | Tax Rate |
|---|---|
| First BDT 3,50,000 | Nil (Tax-free) |
| Next BDT 1,00,000 | 5% |
| Next BDT 3,00,000 | 10% |
| Next BDT 4,00,000 | 15% |
| Next BDT 5,00,000 | 20% |
| Balance above BDT 16,50,000 | 25% |
Enhanced Tax-Free Thresholds for Special Categories
| Category | Tax-Free Threshold (BDT) |
|---|---|
| Female taxpayers | 4,00,000 |
| Senior citizens (65 years and above) | 4,00,000 |
| Persons with disability | 4,75,000 |
| Third gender taxpayers | 4,75,000 |
| Freedom Fighters (Gazetted) | 5,00,000 |
Minimum Tax: Even if your computed tax is zero, a minimum tax of BDT 5,000 is payable if you have a TIN and your name appears on a specified list of mandatory return filers (e.g., city corporation areas, owners of motor vehicles, registered professional licence holders).
For the most current figures, always refer to the official National Board of Revenue (NBR) website or consult our tax consultancy team.
How Income Is Classified for Tax Purposes
Bangladesh’s Income Tax Act 2023 classifies income into seven heads:
- Salaries — Basic pay, allowances, bonuses, perquisites from employment
- Interest on Securities — Government securities, bonds, debentures
- Income from House Property — Rental income from buildings and land
- Agricultural Income — Income from farming, horticulture, or forestry
- Income from Business or Profession — Profits from trade, commerce, or professional services
- Capital Gains — Gains from the sale of capital assets (land, shares, etc.)
- Income from Other Sources — Dividends, lottery winnings, royalties, and other miscellaneous income
Your gross taxable income is the sum of income across all applicable heads, after allowable deductions and exemptions within each head.
Step-by-Step Income Tax Calculation Process in Bangladesh
Step 1: Determine Gross Total Income
Add up all income from the seven heads above for the income year (July 1 – June 30).
Step 2: Claim Allowable Deductions
Common deductions include:
- House Rent Allowance (HRA): Lower of actual HRA received, 50% of basic salary, or rent paid minus 10% of salary
- Medical Allowance: Up to BDT 1,20,000 per year is exempt from tax
- Conveyance Allowance: Up to BDT 30,000 per year
- Business expenses: Documented operational costs for self-employed taxpayers
- Depreciation: On business assets per NBR-prescribed rates
Step 3: Calculate Taxable Income
Taxable Income = Gross Total Income − Allowable Deductions and Exemptions
Step 4: Apply Applicable Tax Slab Rates
Apply the progressive slab rates to your taxable income as shown in the table above.
Step 5: Claim Tax Rebates
Bangladesh allows tax rebates (not deductions) for certain investments and expenditures. The rebate rate is 15% of the eligible investment amount, subject to limits:
| Eligible Investment / Expenditure | Maximum Eligible Amount |
|---|---|
| Life insurance premium | Actual premium paid |
| Contribution to Provident Fund | Actual contribution |
| Investment in DPS (Deposit Pension Scheme) | Up to BDT 1,20,000/year |
| Purchase of savings certificates (Sanchayapatra) | Actual amount |
| Investment in approved mutual funds / stocks | Actual amount |
The maximum investment on which a rebate can be claimed is the lower of: 25% of taxable income, BDT 1,50,00,000, or the actual amount invested.
Step 6: Calculate Net Tax Payable
Net Tax Payable = Computed Tax − Tax Rebate − Tax Already Deducted at Source (TDS)
If the result is negative, you are entitled to a refund.
Corporate Income Tax Rates in Bangladesh
For companies and entities, the following rates apply for FY 2024–25:
| Entity Type | Tax Rate |
|---|---|
| Publicly traded companies (listed on stock exchange) | 22.5% |
| Non-publicly traded companies | 27.5% |
| Banks, insurance, and financial institutions (listed) | 37.5% |
| Banks, insurance, and financial institutions (non-listed) | 40% |
| Mobile phone operators | 45% |
| Tobacco manufacturers | 45% |
| Cooperative societies | 15% |
Companies are required to pay Advance Income Tax (AIT) in four quarterly instalments during the income year. Failure to pay advance tax results in interest charges under Section 176 of the Income Tax Act 2023.

How to File an Income Tax Return in Bangladesh
Mandatory Return Filers
Since FY 2022–23, individuals with a TIN are required to file a return if they fall under specific categories, including: residents of city corporations, owners of motor vehicles, holders of professional licences, and those with income above the tax-free threshold.
Filing Process
- Obtain or verify your e-TIN via the NBR e-TIN portal
- Collect all income documents — salary certificates, bank statements, rental agreements, business accounts
- Prepare your IT-11GA form (for individuals) or relevant corporate form
- Calculate taxable income and tax liability as outlined above
- Pay any outstanding tax via designated bank branches or online (A-Challan)
- Submit the return online via the NBR e-Return portal or physically at your designated tax circle
- Collect the acknowledgement receipt — this serves as proof of filing
The deadline for individual return submission is November 30 of the assessment year. Extensions are available in exceptional circumstances upon application to the Deputy Commissioner of Taxes.
Common Mistakes to Avoid in Income Tax Calculation
Many taxpayers in Bangladesh inadvertently make errors that result in penalties or excess tax payments. The most common pitfalls include:
- Failing to declare all sources of income, including freelancing income, rental income, or interest earned on fixed deposits
- Claiming inadmissible deductions or inflating business expenses without supporting documentation
- Missing the investment tax rebate by not submitting proper proof of eligible investments
- Ignoring TDS (Tax Deducted at Source) certificates from employers or financial institutions, which reduce final liability
- Filing after the November 30 deadline, which triggers automatic penalties
Working with a professional tax consultancy like SAM & Associates ensures these errors are identified and corrected before your return is submitted.

Frequently Asked Questions (FAQs)
1. What is the income tax-free threshold in Bangladesh for FY 2024–25?
For general individual taxpayers, the tax-free threshold is BDT 3,50,000. Female taxpayers and senior citizens (65+) enjoy a higher exemption of BDT 4,00,000, while persons with disability and third gender taxpayers are exempt up to BDT 4,75,000. Income above these thresholds is taxed at progressive slab rates starting at 5%.
2. How is investment tax rebate calculated in Bangladesh?
The rebate is 15% of the eligible investment amount. The maximum investment eligible for rebate is the lower of: 25% of your taxable income, BDT 1,50,00,000, or the actual amount invested in approved instruments (life insurance, DPS, savings certificates, mutual funds, etc.). For example, if your taxable income is BDT 10,00,000 and you invested BDT 2,00,000 in eligible instruments, your rebate is 15% × BDT 2,00,000 = BDT 30,000.
3. Do freelancers and self-employed individuals have to pay income tax in Bangladesh?
Yes. Freelancers, consultants, and self-employed professionals must declare their income under the “Income from Business or Profession” head. However, they can deduct legitimate business expenses such as office rent, equipment, internet charges, and professional fees. Many freelancers also benefit from special provisions for remittances received in foreign currency. A tax consultant can help structure your declarations optimally.
4. What happens if I miss the income tax return filing deadline in Bangladesh?
The standard deadline is November 30. Missing it results in an automatic penalty under Section 174 of the Income Tax Act 2023 — typically 2% per month on the unpaid tax, plus a fixed penalty that the Deputy Commissioner of Taxes may impose. If you have already paid your tax but simply missed filing the return, the penalty is lower but still applicable. It is always advisable to file on time or seek a deadline extension in advance.
