Frequently Asked Questions

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. See our Privacy Policy for details.

India, the USA, the UK, Canada, the UAE, Australia, and Singapore are live today, each with a full set of calculators and guides. More countries are planned — see our full country list.

Every page shows the tax year or Year of Assessment it reflects, along with a last-reviewed date. We aim to review figures whenever a country's tax authority publishes rate or bracket changes, typically once a year around each country's budget cycle.

These calculators are designed for planning and estimation, not as a replacement for professional advice or official filing software. For anything beyond a simple estimate — especially with multiple income sources, business income, or cross-border complexity — a qualified accountant or tax advisor is strongly recommended.

Yes, please do — accuracy matters to us. Use the contact page to flag an outdated figure, suggest a new calculator, or request a country we haven't covered yet.

Not always mandatory, but often a good idea. You're required to file if your gross income exceeds the basic exemption limit, if you meet certain conditions (foreign travel spend, large deposits, etc.), or if you want to claim a TDS refund.

If you're salaried with no business income, yes — you can pick a different regime each financial year when filing. If you have business or professional income, switching back to the Old Regime after choosing New has restrictions.

A W-2 employee has taxes withheld automatically, and their employer pays half of Social Security/Medicare tax. A 1099 contractor gets gross pay with no withholding, pays quarterly estimated taxes themselves, and owes the full 15.3% Self-Employment Tax. See our full comparison.

Our core calculators cover federal tax only, unless a specific calculator states otherwise. Most states also levy their own income tax with separate brackets, and a few states have no income tax at all.

Yes. Income tax and National Insurance are calculated separately, using different thresholds and rates, and both are typically deducted from your pay through PAYE.

Scotland sets its own income tax bands, which differ from the rest of the UK. Our UK calculators reflect rUK (England, Wales, Northern Ireland) rates unless stated otherwise.

It depends on your income trajectory. An RRSP tends to suit higher earners now who expect a lower rate in retirement, since contributions are deductible today. A TFSA suits situations where you might need the money sooner, since withdrawals are always tax-free. See our full comparison.

Our core calculators cover federal tax rules; provincial/territorial income tax is calculated separately and shown where indicated, since each province sets its own brackets.

No. The UAE does not levy personal income tax on salaries or wages. VAT (5%), Corporate Tax (9% above a threshold), and Excise Tax still apply to specific transactions and businesses. See our full explainer.

Possibly — some countries (notably the US) tax based on citizenship rather than residency. Always check your home country's rules on foreign income and tax residency separately from UAE rules.

Most residents pay a 2% Medicare Levy on top of income tax, with a phase-in for low incomes and some exemptions. Higher earners without private hospital cover may also pay the separate Medicare Levy Surcharge.

No. Your employer's compulsory 12% Super Guarantee contribution is taxed concessionally within your super fund (generally 15%), not at your marginal income tax rate.

No. CPF contributions are mandatory only for Singapore Citizens and Permanent Residents. Foreigners on an Employment Pass, S Pass, or Work Permit do not contribute to CPF. See our full explainer.
