Deductions
Taken off your total income to reach taxable income.
- Salary Exemption (one third, up to ৳5,00,000): one third of Salary / Income plus Festival Allowances, Bonuses and Other Salary Receipts (yearly), up to ৳5,00,000. Applies to: Private-sector job, or no salary.
Investment rebate
The rebate reduces your tax. It is the lowest of the following, and never more than the tax itself:
- 10% of your eligible investments and donations
- 3% of your taxable income
- ৳7,50,000
Minimum tax
If your taxable income is above your tax-free threshold, your tax after rebate is at least ৳5,000.
For someone filing a return for the first time, the minimum is ৳1,000.
Tax already paid
These are taken off your tax to give your estimated tax payable:
- Tax Already Deducted This Year (TDS)
- Advance Tax Paid This Year
If the tax you have already paid is more than your liability, your estimated tax payable is ৳0 and the difference is shown separately as excess tax credit. TaxHisab does not say whether it is refundable.
Other years: 2025-26
