Frequently asked questions

What is the difference between VAT, GST, and Sales Tax?

VAT (Value Added Tax) is charged at every stage of production and collected incrementally. GST (Goods & Services Tax) is similar but often replaces multiple indirect taxes with a single levy. Sales Tax is typically applied only at the final point of sale to the consumer.

Can I use this for US state-level taxes?

Yes — select "United States" for a baseline federal rate, then adjust the rate field manually to match your state and local rate. For example, California charges about 7.25% state tax, but combined local rates can be higher. The Custom Rate mode lets you enter any percentage freely.

What does "Extract Tax from Total" mode do?

If you already paid a tax-inclusive price and want to know how much was tax, use Extract mode. Enter the total amount you paid, select the applicable tax rate, and the calculator will reverse-engineer the base price and exact tax amount for you.

How accurate are the pre-filled tax rates?

We maintain standard national rates for 30+ countries and update them periodically. Local or state-level rates can vary — always confirm with your tax authority for official filings or business compliance purposes.
