IRPF withholding on a professional invoice is an advance towards the recipient's income tax, where the applicable rules require it. It is a separate matter from IVA. A professional and a business customer should therefore understand the invoice's components rather than treating the bank transfer as the whole transaction.
First identify the nature of the activity, the recipient of the income and the payer's status. Not every invoice issued by someone who is self-employed has identical withholding treatment. Check the applicable rules and any supported circumstances affecting the treatment instead of copying a percentage from an unrelated supplier's invoice.
For the customer, the review extends beyond paying the net amount. Where it is obliged to withhold, it must arrange the relevant reporting and payment to the tax authority and maintain reliable recipient information. The professional should reconcile the withheld amounts with payment records and the information available for the annual income tax return.
Consider a hypothetical engineering consultant who invoices a Spanish business customer. The invoice shows the professional fee, IVA and an IRPF withholding amount, while the bank transfer reflects the resulting net payment. Her records must preserve the gross income and the withholding separately. Recording only the bank receipt as revenue would lose part of the economic explanation.
Agree a simple exchange of information before the first payment. The professional supplies correct identification and any relevant supporting communication; the customer confirms how it will process the invoice. If either party discovers a discrepancy, compare the invoice, actual payment and withholding records before deciding what needs correcting.
Common mistakes include treating withholding as a customer discount, deducting it twice when reconciling income and assuming that a correctly worded invoice proves the payer completed its obligations. Keep certificates or equivalent supporting information with the annual records and investigate differences while the underlying documents are still easy to obtain.
A sound process allows both parties to trace the gross fee through the invoice, net settlement and tax information without unexplained gaps. It also keeps VAT and income-tax questions distinct.
