When you add a receipt where the 19% tax applies you would do the following:
- Click on "Receipt related transaction"
- In the transaction details you would enter the total amount (say $119)
- In the account allocation you would add two lines:
- Line 1 would be something like general sales $100 (assuming the income was from sales)
- Line 2 would be the tax liability and be $19
When you run the report the taxes you paid would be listed separately. You can create/label your own tax liability using through "Options" --> "Accounts".
The answer is that you would do it manually as you add each receipt and split the income between a tax liability account and the source of the income.
