Tax worked out, step by step
Slab tax, investment rebate, minimum tax, the net-wealth surcharge and the filing incentive or extra tax, each line in whole taka as the e-return shows it.
Bangladesh personal income tax
Know your income tax as you go.
Kor is a private Android app. Record income, investments and tax paid through the year. See what you owe, how much more you can invest for the rebate before 30 June, and get your wealth statement ready for the e-return.
Pre-alpha, for tax year 2026-27. Kor is not released yet: write to us and we will tell you when it is ready.

Where you stand, at a glance
The home screen shows what you still owe, how much is already covered by tax deducted at source, and the filing deadline that applies to you, with a checklist of what is left to fill in.
- A balance that counts to its new value when you change a figure
- A progress ring for tax already paid, and the filing window you are in
- A checklist that tells you what is missing, or by how much your wealth statement is out
What Kor does
A rebate planner
While the income year is open, see how much more to invest by 30 June and exactly what it saves, stopping where minimum tax takes over.
A wealth statement that checks itself
IT-10B and IT-10BB in the e-return's layout, with the same reconciliation NBR applies. Kor tells you whether it balances and, if not, by how much and which way.
An e-return summary
Every figure under its e-return line number. Tap a line to copy its amount, or save the whole summary as a PDF.
A calculator for every amount
Type sums such as 45,000 × 12 on a built-in keypad with lakh grouping. Bangla digits show when the app is in Bangla.
Reminders, only if you want them
A note before the early-filing incentive ends, before extra tax starts or goes up, and before 30 June for investments. Reminders never show an amount.

Your figures never leave your phone
Kor has no internet permission, so it cannot send anything anywhere. Your figures are saved on the phone only, sealed with a key held in Android's Keystore.
- No account, no sign-in, no analytics, no advertising, no crash reporting
- Excluded from Android backup and device transfer
- Notifications only if you turn reminders on, and they never show amounts
- Check it yourself: Kor asks for no internet permission, which your phone's app settings show
What works today, and what does not yet
Kor is pre-alpha. The rules for tax year 2026-27 (income 1 July 2025 to 30 June 2026, the return filed in late 2026) come from NBR's Income Tax Guide 2026-27, the Finance Act 2026 and the Income Tax Act 2023, and the tests reproduce the guide's worked examples.
