Changing your tax rate
Written by Maya Okafor · Last verified 2 October 2026 · 2 min readMaya Okafor · Last verified 2 October 2026
Tidewater adds your default tax rate to every new invoice. You can change that default at any time, or set a different rate for a single client. Changes apply to invoices you create from now on.
Change the default rate
- Open Settings and select Taxes.
- Under Default tax rate, select Edit.
- Enter the new rate, for example 21%, and give it the name your clients should see on the invoice, such as VAT.
- Select Save rate. The next invoice you create uses the new rate.
Set a rate for one client
Some clients need a different rate, for example a business in another EU country. Open the client, select Tax settings and choose a rate. Tidewater uses it for that client only and keeps your default for everyone else.
Fix an invoice you already sent
If an invoice PDF shows the wrong tax rate, open the invoice and select Issue corrected invoice. Tidewater creates a credit note for the original and a new invoice at the right rate, and sends both to your client.
