Old vs new regime, federal vs state, brackets, deductions — worked out precisely for the country you file in. No signup, no paywall, no email required.
Choose from 7 countries, each built around how that country's tax system actually works — regimes, brackets, federal vs. state, whatever applies.
Plug in your income, deductions, or relevant details into the calculator. Nothing is saved, tracked, or emailed — the calculation happens right in your browser.
See exactly how the number breaks down — bracket by bracket — plus links to related guides if you want the full context before filing.
Each country's calculators are built around its actual tax structure — India's Old vs New Regime, the UK's National Insurance, Canada's CPP/EI, Singapore's CPF — not a generic formula reused everywhere.
Every calculator and guide is free to use, with no account, no email capture, and no artificial limit on how many times you use it.
Every page shows the tax year or Year of Assessment it reflects, along with a last-reviewed date, so you know exactly how current the figures are.
Results show the full breakdown — which bracket applied, what got deducted, what the effective rate works out to — instead of just a single final number.
Yes. Every calculator, guide, and reference page on this site is completely free — no signup, no account, no paywall, and no limit on how many times you use them.
Our calculators are built from publicly available tax rules and reviewed periodically, but they produce estimates for planning purposes, not final or authoritative figures. Tax law changes frequently and individual situations vary, so always confirm your final numbers with a qualified tax professional or your country's official tax authority before filing. See our full disclaimer.
No. Calculations run directly in your browser — the income figures and personal details you enter into a calculator are never transmitted to or stored on our servers.
