The withholding is worked out on the base, never on the total with VAT. That is why the gap in the lower bar measures exactly the same as a slice of the dark blue part above it.

Which rate to use

VAT depends on what you sell. Withholding depends on who invoices and who pays

21% is the general VAT rate. The 10%, 4% and 0% rates apply only to specific transactions. For withholding, this quick rule covers the usual cases.

21 %

General

Most goods and services.

10 %

Reduced

Hospitality, transport and other cases.

4 %

Super-reduced

Essential goods listed in law.

0 %

Zero rate

Only specific transactions.

1 · Who receives the invoice?

2 · What kind of activity is it?

Usual outcome

15% withholding

Professional work invoiced to a business or another professional usually carries the general withholding.

Some activities, territories and transactions have special rules. This result helps you choose in the calculator; it is not a tax classification of your case.

The right calculation

VAT and IRPF start from the same base and move in opposite directions

VAT is added. Withholding is subtracted. Neither is calculated on the invoice total.

  1. 1

    First, the base. It is the price of your work before tax and the reference for both calculations.

  2. 2

    Then, VAT. The VAT charge is added to the base to get the total including VAT.

  3. 3

    Finally, withholding. It is deducted from what the client pays and sent to the tax authority in your name.

What people usually ask

What people ask with the invoice half written

Rates are not a matter of convenience. If your transaction has an exemption, a special scheme or several rates, confirm the treatment before issuing the invoice.

Neither: they run in parallel. The VAT is added to the base and the withholding is taken off the base. Both lines hang from the same figure, so the order you write them in on the invoice makes no difference.
