📋 I got a tax demand or enforcement notice I think is wrong — who do I contact?

Direct answer

Tax letters have short deadlines — usually 30 days to object — and enforcement starts automatically after that, so act on the date, not on the merits. Object in writing to Agencia Tributaria — recursos y aplazamientos (901 200 345) with the assessment number and why it is wrong, and ask for enforcement to be suspended while they look at it. If the office does not answer or treats you unfairly, Defensor del Pueblo (900 101 025) takes complaints about the tax administration. For a real dispute about the amount, Colegio de Abogados — turno de oficio / justicia gratuita (abogacia.es) can tell you whether appealing to the tax court makes sense.

🗣️ What to say

"I object to assessment [number] dated [date]. The amount is wrong because [reason: income already taxed / expenses not deducted / not my income]. I ask you to correct it and to suspend collection until you have decided. Please confirm receipt."

🪜 Step by step

  1. Find the deadlineIt is printed on the letter. Objection filed on time keeps all your rights; one day late loses most of them.
  2. Object in writingOnline portal or letter. Assessment number, what is wrong, the evidence. Ask explicitly for suspension of collection.
  3. Cannot pay even if it is right?Ask for a payment plan in the same letter. Tax offices grant them routinely if you ask before enforcement.
  4. No answer or unfair treatment: Defensor del PuebloThe ombudsman takes complaints about delays, lost documents and rudeness, not about the tax law itself.
  5. Real dispute: Colegio de Abogados — turno de oficio / justicia gratuitaLegal aid can assess the appeal to the tax court and whether the costs are worth it.

❓ Frequently asked

Does objecting stop the bailiff?

Not automatically everywhere — that is why you ask for suspension explicitly. In many countries a timely objection suspends collection of the disputed part.

The letter looks like a scam

Tax offices never ask for payment by voucher, crypto or to a foreign account, and never call to threaten arrest. Check the assessment in your online tax account before paying anything.

I missed the deadline

Ask for a late objection with the reason (illness, absence, letter not received). It is sometimes accepted; otherwise a request for a correction on equity grounds is still possible.
