An investment tax rebate is a legal provision that allows taxpayers to substantially reduce their final income tax payable by investing a portion of their income into government-approved financial sectors. To claim this rebate in Bangladesh, an individual taxpayer must consciously allocate funds into specific eligible areas during the ongoing income year.

The most common and popular approved investments include the purchase of National Savings Certificates (Sanchayapatra), deposits in a Deposit Pension Scheme (DPS) up to a specified annual limit (often capped at BDT 120,000), life insurance premium payments, and investments in the capital market, such as publicly traded stocks or mutual funds. The actual rebate amount is calculated based on a strict formula set by the NBR. Generally, your total allowable investment cannot exceed a certain percentage of your total taxable income (usually around 20%), and the actual tax rebate is typically calculated at 15% of that eligible investment amount. Properly declaring these investments with supporting documents during your annual return submission can lead to massive tax savings.
