# Why is my supplier invoice using the wrong tax code?

KB262

### Overview

Sometimes when you create a supplier invoice that has a tax component, the tax amount may be posted to an account that is different than you expect. If you think that the account to which tax has posted is not correct, then you can check the following.

### Process

#### Check that the inventory items have the correct tax code

#### Check how the invoice was created

If you duplicate a supplier invoice, the tax codes from the duplicated invoice will be copied regardless of the current tax code on any items. You can change the tax codes by following one of the below methods:

- Remove and re-enter the items – this will update the tax code to the current tax code for the item
- Click on the “i” symbol under the item code and change to the correct Tax code

The ability to change the tax code on a supplier invoice is an option in the System Preferences. If the Tax code is not visible and you would like the ability to change the tax code on the supplier invoice, go to Accounts payable > Setup > Preferences > Tick Allow tax codes to be set on supplier invoices.
