Finding your tax codes
Click on Settings
Select Accounting
Choose your accounting system
In the tax code table, add all the VAT rates
Head to the Categories tab and assign a tax code to each category
If you are using an accounting integration
You will not have the tax table above (except for Swedish accounting systems)
Simply select the Categories tab under the Accounting menu
Assign a category and the tax rules will be set by your accounting system
Once the VAT rate is added to a category, all expenses with that category will have that VAT code attached. You can always amend each expense individually in the export stage if needed.
