This income tax calculator estimates personal income tax for Bangladesh and India using each country’s current slabs, and shows exactly how much tax falls in each slab.
Bangladesh: assessment year 2026-27 (income year 2025-26)
According to news reports, when the budget was passed in parliament the tax-free threshold for general individual taxpayers was set at Tk 4,00,000. Above that, the next Tk 3 lakh is taxed at 10%, the next Tk 4 lakh at 15%, the next Tk 5 lakh at 20%, the next Tk 20 lakh at 25%, and the rest at 30%.
Please verify: published reports on the threshold were not fully consistent (some mention Tk 3,75,000), and women, people aged 65+, persons with disabilities, war-wounded freedom fighters and some other groups have higher thresholds. That is why the threshold field is editable. Check the latest Finance Act and NBR guidance before filing your return.
Investment rebate: the calculator uses the lowest of 3% of taxable income, 15% of eligible investment, or Tk 10 lakh. This is our understanding of the rule under the Income Tax Act 2023, but it may have changed.
India: new tax regime, FY 2026-27
The February 2026 Union Budget kept the slabs unchanged: nil up to ₹4 lakh, 5% from ₹4–8 lakh, 10% from ₹8–12 lakh, 15% from ₹12–16 lakh, 20% from ₹16–20 lakh, 25% from ₹20–24 lakh and 30% above ₹24 lakh. The calculator applies the ₹75,000 standard deduction for salaried people, the Section 87A rebate (no tax on taxable income up to ₹12 lakh) and marginal relief just above that level. The old regime and the surcharge on incomes above ₹50 lakh are not covered.
Examples
Bangladesh: on taxable income of Tk 8,00,000, the first Tk 4 lakh is tax-free, the next Tk 3 lakh attracts Tk 30,000 and the remaining Tk 1 lakh Tk 15,000 — Tk 45,000 before rebate. India: on a ₹15,00,000 salary, taxable income is ₹14,25,000 and tax is ₹93,750 plus 4% cess = ₹97,500.
