Income Tax Calculator
Switch between India, UK, and US versions. Each model uses a dated ruleset and shows the assumptions directly in the result card so you can compare faster without guessing what tax year it is using.
Use the HRA page first if you want to estimate HRA exemption automatically.
Assumptions & Scope
The India version uses salaried individual rules with AY 2026-27 slabs, salary standard deduction, rebate under section 87A, and 4% cess. It applies a straightforward surcharge rate above ₹50 lakh but does not model marginal relief.
The UK version uses the 6 April 2025 to 5 April 2026 PAYE rates and employee National Insurance thresholds. It assumes the standard personal allowance and does not model student loans, special tax codes, benefits-in-kind, or marriage allowance transfers.
The US version uses 2026 federal brackets, 2026 standard deductions, 6.2% Social Security up to the 2026 wage base, 1.45% Medicare, and Additional Medicare Tax where applicable. State tax is an optional flat estimate rather than a state-specific calculation engine.
