Creating New Tax Codes
Updated 31 October 2026
Aedon comes with the tax codes most organisations need, so you will rarely need to create one. Check with your accountant before adding a code, and look at a similar existing code to see how it is set up.
Create a tax code
- Click the App Launcher (the grid of dots, top left), search for Tax and open it, click the Tax Codes tab and click New(1).
- Enter the VAT Code, Rate and Description.
- Choose the Type, Product Type, Category and Additional Category. See UK VAT Codes (Tax Codes) for what each one does.
- If necessary, add some Examples to help users choose the code, and tick Is EC if it is for Northern Ireland and EU goods.
- Tick Active and click Save.
