Have you found that when you applied the map, the lines are ticked as taxed but the rate is 0%?
This issue occurs because Smart Extract applies zero tax to taxed lines when the supplier’s default tax rate is set to 0%. As a result, the extracted total reflects only the subtotal, excluding GST.
Check your Supplier's default tax code
Go to Suppliers and select the supplier
Select Edit.
If 'Default Tax Code' is 'No GST', 'GST Free', or similar, remove it and leave this field blank.
Refresh the page.
Apply the map.
The 'Default Tax Code' field is best left blank to allow the maps to work correctly. Lightyear will use the two default company tax rates you've set. Only in special circumstances would you need to select a different default tax code.
Check your default tax rates
If after making changes to your Supplier the problem still occurs, check that the company's default Tax Rates you've ticked are correct.
You can check this by selecting Edit next to Tax Rates.
📌 Note: You must select one Default Tax and one Default Tax Free.
Your tax rates are defined in two separate columns. Be sure to select one from each column to enable the default tax and tax-free rates on your account.
