How Sage Selects the Default Tax Code

When you enter a transaction, Sage 50 Accounts automatically applies a default tax code based on the information available. This helps speed up data entry and reduces the need to select a tax code manually for every transaction.

The default tax code is typically determined by:

  • The default tax code assigned to the customer or supplier record.

  • Your company or transaction settings, where applicable.

If the automatically selected tax code isn’t appropriate for a particular transaction, you can choose a different one before saving the entry.

  • Check your tax code settings whenever VAT rules are updated.
  • Avoid modifying existing tax codes without understanding their impact on VAT reporting.
  • Test any new or custom tax codes before using them for day-to-day transactions.
  • If you’re unsure which tax code to use, seek advice from your accountant or tax professional.

Common Mistakes to Avoid

Using the wrong tax code can affect your VAT calculations and lead to reporting errors. Before posting a transaction, always check that you’ve selected the correct tax code. It’s also a good idea to avoid changing the default tax codes unless you’re sure of their purpose.
