Tax Calculators
Estimate sales tax, VAT, and income tax for the US, UK, India, and more.
Sales tax, VAT, and income tax work differently enough across the US, UK, India, and other regions that a single generic calculator can't honestly cover all of them -- these are separated by region specifically because a US sales tax calculation and an EU VAT calculation aren't the same math wearing different labels, they're genuinely different systems, and treating them as interchangeable would give wrong answers.
