Tax Calculator BD

Tax Calculator BD is an Android app I built to estimate Bangladesh income tax. Enter your income and investment, and it shows the tax due, every step of the sum, what investing more could save, and when to file.

Every step of the sum

• A live estimate for the 2026–27, 2027–28 and 2028–29 assessment years.
• Salary exemption, tax slabs, minimum tax and wealth surcharge, with a slab-by-slab breakdown, take-home pay and effective rate.
• A rebate slider that shows how much tax more investment would save.
• Every taxpayer category, including gazetted war-wounded freedom fighters and injured July Warriors.
• A filing planner with the rebate or extra tax for each filing window, a countdown and a calendar reminder.
• Saved TINs and a link to the official return verification page.

Up to date with the law

Rates, limits and the rebate follow the Income Tax Act 2023 as amended by the Finance Act 2026, checked against the official gazette. The app works in Bangla and English, needs no account and keeps figures on the phone. It is free and shows adverts.

It is an unofficial helper and is not affiliated with the National Board of Revenue.
