You can add custom tax codes for any tax codes you need. You can also edit the rates for any of the custom taxes you set up in QuickBooks Online.
To edit a tax code that you added:
- In the navigation bar, click Taxes (or Sales Tax) > Tax (or Sales Tax, VAT, or GST depending on what you see).
- Click Edit VAT > Edit rates.
- Click Edit next to the tax code you want to change.
- Make your changes and click Save.
Changes to the tax code will apply to any future transactions you add it to. If you need to change the tax rate for an existing transaction, open that transaction and edit the rate manually.
