You get a proportional VAT deduction on individual vouchers by creating a custom VAT code under Administration → Accounting → Custom VAT codes.
Custom VAT codes (proportional deduction)
If only some invoices should have a proportional deduction (partial VAT deduction), you can create a separate VAT code in addition to the standard codes:
Go to Administration → Accounting → Custom VAT codes.
Click New VAT code.
Fill in the New VAT code window:
Name – e.g. "Proportional 50%".
Description (optional).
Share – the share that is deductible (e.g. 50).
VAT code – the standard code the deduction applies to (e.g. code 1, purchase at high rate).
Click Create VAT code. The code now appears as a separate option when posting, in addition to the standard codes.
Continue to use the regular VAT code on everything else – the custom code is used only on vouchers that should have a proportional deduction.
Will the code be used on customs declarations?
Then select an import VAT code (81–85), e.g. 81, as the VAT code. Only custom codes based on an import VAT code appear in the VAT code list on a customs declaration. A code based on a regular purchase code (e.g. 1 or 14) won't appear there. See Posting a Customs Declaration.
Why is there an "odd" percentage in the Percentage column?
The percentage shown in the Percentage column (e.g. 2.25% or 11.11%) is not the share you chose, but the effective VAT rate the system calculates from the share. This is correct and ensures that VAT is calculated correctly when posting, where you enter the total amount including VAT.
