Free seller tools
Check tax exposure or verify the amount on an order.
Use the exposure check for registration, marketplace, stock, and import questions. Use the calculator only for invoice and checkout arithmetic.
Tax exposure check
Tell us where you sell, the current registration status, how each market is fulfilled and the approximate sales involved. The result separates marketplace collection evidence from the seller-controlled sales and other facts that still need review.
Your business setup
1. Where is your business legally established?
2. Which markets do you sell to?
3. Which channels do you use in each market?
Select markets in question 2 first.
7. Typical order or parcel value in each market?
8. Mostly B2C or B2B?
This is a preliminary self-check, not tax advice. Decisions on registration, tax charging or collection, return filing and payment should be confirmed with a qualified professional. Questionnaire answers are used only to generate the result; see the Privacy Policy for details.
Invoice and checkout calculator
Add or remove VAT, GST, or sales tax. This calculates amounts; it does not decide whether registration or collection is required.
- Net
- £100.00
- VAT Tax
- £20.00
- Gross
- £120.00
Add tax multiplies net by 1 + rate. Remove tax divides gross by 1 + rate.
Use this for invoice and checkout maths. It does not decide whether you must register, collect, or file.
Rate references
Use the official or exact destination rate before issuing an invoice. US state and local rates depend on the customer location.
