Frequently Asked Questions
Sales tax rates vary by location. In the US, state rates typically range from 0% to 10.25%. The UK uses VAT at a standard rate of 20%, a reduced rate of 5% for certain goods, and 0% for essentials like food and children's clothing.
To remove sales tax from a gross (tax-inclusive) price, divide by (1 + rate/100). For example, to remove 20% tax from £120, divide by 1.20 to get £100 net. This tool does that automatically when you click "Remove Tax".
Sales tax is applied only at the point of final sale to the consumer, common in the US. VAT (Value Added Tax) is collected at each stage of the supply chain, common in the UK and EU. Both result in the consumer paying tax on top of the base price.
