U.S. mode uses an IRS-compatible general sales-tax style calculation approach for 2025, while allowing you to enter the actual combined state and local rate used on the transaction. Because the U.S. uses sales tax rather than VAT, this panel helps you price invoices, retail totals, and reverse-tax amounts using your own jurisdiction rate.
Choose whether your amount already includes tax or whether tax should be added on top.
Select the state for record-keeping and printed reports. Rate entry stays editable because local taxes vary by city and county.

Frequently Asked Questions

How do I add VAT to a price?

Multiply the net price by 1 plus the VAT rate. At the UK standard rate of 20%, a £100 net price becomes 100 × 1.20 = £120 including VAT.

How do I remove VAT from a gross price?

Divide the VAT-inclusive price by 1 plus the rate. For a £120 price at 20%, the net amount is 120 ÷ 1.20 = £100, so the VAT is £20.

What are the UK VAT rates?

The standard rate is 20%, a reduced rate of 5% applies to items like domestic energy and child car seats, and some goods (most food, children's clothes, books) are zero-rated at 0%.

When do I have to register for VAT?

A UK business must register once its VAT-taxable turnover exceeds the registration threshold in a rolling 12-month period, though it can register voluntarily below that to reclaim input VAT.
