Frequently asked questions about VAT and IRPF
How is the invoice total calculated?
VAT is added to the taxable base and IRPF withholding is deducted. The withholding is an advance income-tax payment made on behalf of the professional.
When does the 7% IRPF rate apply?
It may apply in certain cases when starting a professional activity. Always check that you meet the current requirements.
Can I use a different rate?
Yes. The calculator accepts custom rates when the transaction does not use one of the standard values.
