Spain: the one certificate that limits the seller's tax debts when you take over the business
By Grig Kochedykov · . Legal points checked against official sources on 4 October 2026.
Before you take over a business in Spain, ask the Spanish tax agency (AEAT) for the certificate under article 175.2 of the General Tax Act. With the seller's consent, it caps your liability for the tax debts the seller left from running the business at what it lists, and removes it if it shows nothing owed or does not arrive within three months.
General information, not legal or tax advice.
Why you need it: the seller's tax debts can follow the business
Article 42.1.c of the General Tax Act makes whoever succeeds "in the ownership or exercise" of a business jointly and severally liable for the previous holder's tax debts from running it. Jointly and severally means the tax agency can, by a formal decision after hearing you, declare you liable for the debts the previous holder left from running the business and demand them from you, without chasing the seller first. It also covers tax the seller withheld, or should have withheld, for example from wages, and did not pay in.
Buying the equipment and stock on separate contracts does not avoid it: the exception for "isolated elements" falls away when what you bought lets the activity carry on. Outside this rule: inheritance (heirs fall under article 39 instead), and buying inside a formal insolvency procedure.
What the certificate does
Article 175.2 gives the future buyer the right to ask the tax agency for a "detailed certification" of the activity's tax debts, penalties and liabilities. On its wording ("whoever intends to acquire"), you can ask only before the deal. What follows from its text:
| What happens | Your liability for the seller's tax debts |
|---|---|
| The certificate lists debts | limited to the debts, penalties and liabilities it lists |
| The certificate lists nothing | none |
| No certificate within three months of your request | none |
| You never asked | the full rule, and it also reaches "the penalties imposed or that may be imposed" |
The last row comes from article 42.1.c: not asking adds the seller's fines to what can be claimed from you.
How to get it, step by step
- Get the seller's consent in writing, before you agree the price. The right is yours, but only "with the prior consent of the current holder". In writing: "I want to request the certificate under article 175.2 of the General Tax Act. It needs your consent. Will you sign it this week?"
- File the request with the AEAT. Ask your gestor to file it and to hand you the receipt with the filing date. In Spanish, ask for the certificación del artículo 175.2 de la Ley General Tributaria.
- Wait. The agency must issue it within three months of the request. Do not complete before the certificate arrives or the three months run out.
- Keep the request, the receipt and the dates with your contract. If nothing arrives, the receipt is what proves the three months have passed.
A list of debts is a good result: the unknown has become a number you can take off the price.
If the seller will not sign
Ask why. "Not until we have a signed agreement" is a reasonable answer: ask your lawyer for a preliminary agreement that makes completion conditional on the certificate. "No, and no reason" is a different answer. A refusal is not proof of a debt. On the wording of the law, a refusal leaves you in the same position as never asking: no cap, and the penalties on top. Then the choice is to walk away or to price the unknown; ask your lawyer how a retention should be worded.
What it does not cover
Social Security debts. A separate debt under a separate law, untouched by this certificate. Article 142.1 of the General Social Security Act makes the buyer jointly liable for "the totality of the debts generated" before the takeover. Article 168.2 says certificates guaranteeing a buyer's "non-liability" are to be set out in regulations. Royal Decree 1415/2004 (Social Security collection), Order TAS/1562/2005 and Royal Decree 84/1996 (employer registration, article 19) contain no such certificate. That does not prove it exists nowhere, but plan without it.
Debts owed to other administrations. Regional and municipal taxes are run by other administrations, and the AEAT certificate does not list their debts. Whether you can ask those offices for the same certificate we have not checked: ask your gestor.
Staff and suppliers. Staff contracts pass to you by labour law (article 44 of the Workers' Statute) when the business carries on as a unit. Supplier debts are not covered either: each is its own check.
Owners before your seller. The certificate needs the current holder's consent. Whether earlier holders' debts can reach you, and how far the certificate protects you then, is open: on 29 May 2026 the Supreme Court agreed to hear an appeal on exactly those two questions, which is not yet a ruling. In that file a hotel business had passed through three companies; the tax agency declared the third liable for €129,176.32 of the first one's debts, and the regional tax tribunal noted that nothing on file showed a request for the certificate.
A "tax clearance" from the seller. A certificate that the seller is up to date with their taxes is a different document. Article 42.1.c mentions a limit on liability only in connection with the 175.2 certificate. Our reading: a certificate from the seller that they are up to date does not give you that limit. Ask your gestor or lawyer before you rely on any other paper.
What to ask your gestor or lawyer to write into the contract
- the seller's consent to the 175.2 request, signed and dated;
- completion only after the certificate arrives or three months pass from the request;
- if it lists debts: the seller pays them before completion, or the price drops by that amount;
- a retention against Social Security and wage debts, released against an event you can see (a document from the seller, an up-to-date certificate from the relevant administration), not a calendar date (when article 44 applies, article 44.3 of the Workers' Statute makes you and the seller jointly liable for three years for wage and other labour debts the seller left unpaid);
- the seller's promise to repay you for any earlier debt claimed from you: it does not bind the authorities, but it binds the seller. Article 41.6 of the General Tax Act already lets you reclaim the seller's own tax debts from the seller under civil law.
Chapters 8 to 10 of the book "Buying a Small Business in Spain" by Grig Lien cover this in more detail.
Before the deposit: put the request in first
Send the 175.2 request as soon as the seller signs, and let the three months run while everything else happens.
