FAQ
How does sales tax work in the US?
Sales tax is added to the price of goods at checkout and varies by state and locality. For example: California 7.25%, New York ~8%, Texas 8.25%, Florida 6%. Some states have no statewide sales tax.
How do I add sales tax to a price?
Multiply the pre-tax price by the tax rate to get the tax amount, then add it to the price. Example: $1,000 × 7.25% = $72.50 tax, for a $1,072.50 total.
How do I extract tax from a tax-inclusive total?
Divide the total by (1 + rate). Example: a $1,072.50 total at 7.25% gives a $1,000 pre-tax price, so the tax was $72.50. Use the “tax included” toggle to do this automatically.
What is VAT and how is it different?
VAT (Value Added Tax) is used across the EU and many other countries, typically 17–27%, and is usually shown included in the displayed price. US sales tax is normally added at checkout instead.
