We are on IFS Cloud.

IFS calculates Withholding Tax as a % of the NET supplier invoice amount (exclusive of ‘deductible’ VAT/Taxes).

However, Irish Revenue calculates the Withholding Tax on the GROSS supplier invoice amount (inclusive of ‘deductible’ VAT/Taxes).

e.g. supplier invoice = €100 + VAT (sales taxes) €13.5 = gross €113.50 to be paid.  The Withholding tax rate is 20%.  Irish Revenue calculate withholding tax amount of €113.50 x 20% = €22.70, i.e. pay the supplier €113.50 less €22.70 = €90.80 but IFS calculates €100 x 20% = €20 i.e. pay the supplier €113.50 less €20 = €93.50.

I do not appear to have any option/feature in IFS to change the withholding tax amount to automatically calculate based on the Gross amount.

I know that it is possible to manually modify the withholding tax amount in IFS when creating the payment proposal but ideally I want the system to calculate as required first time.

Any thoughts or similar experience in the Community?

Additional info on my issue above - the following is the setting that is currently set which still results on a Withholding tax calculation in IFS based on the NET invoice value (before VAT/taxes):
