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.
