Incorrect anagram or taxpayer NIF

The error "Incorrect anagram" or "Incorrect NIF" may occur when attempting to pay on the AEAT site for self-assessments or tax payments by direct debit or by card.

It is important to check that the first letters entered in the "Surname" field, only for natural persons, coincide with the data that appears in the census for the NIF entered.

You can check if the data is included in the census of the AEAT correctly by accessing "Verification of a NIF of third parties for census purposes" (requires an electronic certificate).

If you have an electronic certificate or Cl@ve PIN, you can also check these details on your Tax Labels.
