Sales tax is an indirect tax on goods and services, typically calculated as a percentage of the price. Rates vary by country/region: China VAT (13%/9%/6%), US sales tax (0-10% by state), EU VAT (15-27%).
Add tax: enter net price (excluding tax), calculate tax and gross price. Remove tax: enter gross price (including tax), reverse-calculate net price and tax. Remove mode is useful for extracting tax from tax-inclusive invoices.
Tax = Gross ร Rate / (1 + Rate). For example, gross price $108.25 at 8.25%: tax = 108.25 ร 0.0825 / 1.0825 = $8.25, net = $100.
China VAT: 13%/9%/6%/3%. US sales tax varies: 0% (Oregon/Montana), 7.25% (California), 8.875% (NYC). EU VAT: 19% (Germany), 20% (France/UK), 21% (Spain).
