The tax office claims your company's debt from you

Last updated 2026-09-01 · Reviewed by Jaime Piñeira Pardo, registered with the ICAM bar, no. 138826

The short answer

The derivation decision must be challenged within one month of notification, either before the same office or before the TEAR (the regional tax tribunal). That challenge may attack both the ground of liability and the assessments demanded from you, under article 174.5 LGT. Once the administrative route ends, two months remain for court proceedings.

You were the director of a limited company that stopped operating three years ago. You heard nothing until a subsidiary liability decision arrived: the collection office demands 84,000 euros of VAT, withholdings and penalties owed by that company, and sets a payment deadline. You think the debt was never yours, that the company closed with no activity and no assets, and that you had long stopped signing anything. Yet the decision reaches your home, your salary and your bank accounts.

The case, in five lines

What is brought
Challenge to the liability decision, attacking both the ground of liability and the assessments derived to you.
Before which court
The collection office that issued it, if you opt for the reposición appeal, or the TEAR (the regional tax tribunal) and then the contencioso-administrativo courts.
Deadline
One month from the day after notification of the decision for the economic-administrative claim, under article 235.1 LGT. Two months from notification of the decision closing the administrative route for the court claim, under article 46.1 LJCA.
Who can bring it
The person declared liable, whether director in law or in fact. Each liable person appeals separately and the outcome only affects the amount of their own obligation.
Financial risk
If the voluntary payment period ends without payment, the enforcement period opens with surcharges and interest and the debt is collected by enforcement. In later court proceedings, costs may be awarded against you if the claim fails.

Without the company being declared insolvent there is no subsidiary liability

Article 41.5 LGT requires an administrative decision that, after hearing the person concerned, declares the liability and sets its scope and extent. It adds something that decides many cases: derivation to subsidiary liable persons requires the prior declaration of insolvency of the main debtor and of the jointly liable persons. If the company was not properly declared insolvent, the decision lacks one of its own conditions, and that is the first line of defence.

That is why the whole file is requested and the insolvency declaration is read with its date in hand. We check whether the collection office genuinely investigated the company's assets, whether it exhausted the jointly liable persons before reaching you, and whether receivables, balances or assets were left unseized. An insolvency declared as a matter of routine, with no real investigation, is a decision that can be attacked at its root.

Having been a director does not by itself make you liable

Article 43.1.a) LGT does not punish the office held, it punishes conduct: it requires that the company committed tax infringements and that the director failed to take the steps within his remit to meet the tax obligations, consented to non-compliance by those under him, or adopted resolutions that made the infringements possible. That is the only ground that expressly extends liability to penalties as well.

Article 43.1.b) LGT is a different ground and is often confused with the previous one. It reaches directors in law or in fact of companies that ceased trading, for obligations accrued and outstanding at the time of the cessation, provided they failed to do what was necessary to pay them or adopted resolutions or measures causing the non-payment. Here the fight is the real date of cessation and which payments were made.

The practical consequence is that the defence is built on facts, not on statements of intent. We show who actually ran the company, what decisions were taken when the obligations accrued, whether suppliers were paid while the tax authority was left out, and whether the cessation was orderly or abrupt. Where the decision merely copies the wording of the statute without anchoring each element in the file, its reasoning collapses.

The same challenge can attack the company's assessments

Article 174.5 LGT is the rule that changes the case. It states that the appeal or claim against the derivation decision may challenge the ground of liability and the assessments covered by that ground. In other words, even if the debt became final for the company, you dispute it for the first time, because until now nobody had called you to defend yourself against it.

The same article sets the limit: the outcome cannot review assessments that became final for other taxpayers, only the amount owed by the liable person who appealed. In plain terms, the company's debt remains what it was, but yours can be reduced or wiped out. That is why the pleading attacks the liability and the substance of each derived assessment at the same time.

Signing acceptance cuts the debt, but appealing later brings it back

Article 41.4 LGT allows you to accept the proposed liability decision where it covers penalties, with the reduction of article 188.1.b) LGT. The trap is in the following paragraph: that reduction will be demanded back from you without more if you lodge any appeal or claim against the decision based on the merits of the derivation or on the derived assessments.

It is a decision taken once and it conditions everything else, so it is weighed before signing anything, not afterwards. On one side sits the certain reduction, on the other the real strength of the grounds of challenge and the amount at stake. Accepting out of immediate relief and then appealing three weeks later is the fastest way to lose both.

One month for the TEAR and two months for the courts, no excuses

Article 235.1 LGT sets one month from the day after notification of the challenged act to lodge the economic-administrative claim. The pleading may simply ask for the claim to be registered, identifying the claimant, the act challenged, the address for service and the tribunal, although it is worth attaching the arguments straight away when the file already allows them to be built firmly.

When the decision arrives, article 46.1 LJCA gives two months from the day after its notification to bring the contencioso-administrativo claim, and article 46.4 clarifies that, where the reposición appeal was used first, time runs from notification of its express decision or from when it must be deemed rejected. If the tribunal does not decide, there is administrative silence, and that route has its own count.

How we run the case, step by step

  1. 1

    Reading the decision and the full file

    Article 174.4 LGT requires notification of the full text of the decision, with the ground of liability and the assessments covered. We check which subparagraph of article 43.1 is applied, which penalties are included, and whether the insolvency declaration appears with its date.

  2. 2

    Submissions while the proposal is still open

    If what arrived is the proposal and not the final decision, we answer within the prior hearing of article 41.5 LGT, providing documents. Article 174.3 LGT also recognises the right to make submissions and produce documents even before that hearing takes place.

  3. 3

    Deciding on acceptance and on suspension

    We weigh which matters more, the reduction under article 41.4 LGT or the grounds of challenge, and we prepare the security so the debt is not collected while it is being disputed. Without suspension, collection continues even though the challenge is pending.

  4. 4

    Reposición appeal or TEAR claim within one month

    It is lodged within the month set by article 235.1 LGT, attacking in the same pleading both the ground of liability and each derived assessment, relying on article 174.5 LGT. Whatever is not argued here is very hard to recover later on.

  5. 5

    Contencioso-administrativo claim within two months

    If the outcome is unfavourable, article 46.1 LJCA opens two months to go to the contencioso-administrativo courts. There the nullity of the decision is argued again, an interim suspension is requested, and the evidence the administrative route refused to take is finally produced.

The evidence that decides the case

  • The file declaring the company insolvent, with its date and the asset investigation carried out to support it.
  • The deed or resolution of removal or resignation from office and its entry at the Registro Mercantil, to fix until when you were in charge.
  • Bank statements and accounting records for the months when the obligations accrued, showing who was paid and in what order.
  • The penalty decision issued against the company and its reasoning on culpability, where the derivation extends to penalties.
  • The notifications of the derived assessments and their delivery records, to establish whether the company could defend itself and at which address.
  • Minutes of shareholder meetings and internal emails showing who actually took the decisions in the company.

What closes the door

  • Letting the month of article 235.1 LGT run out on the assumption that the debt is not yours. Once it expires the decision becomes final and your personal assets are exposed.
  • Signing acceptance to obtain the reduction and appealing afterwards: article 41.4 LGT allows it to be demanded back without more where the appeal is based on the derivation or on the assessments.
  • Challenging only the liability and not the derived assessments, wasting the single opportunity article 174.5 LGT gives to dispute the substance of the debt.
  • Not requesting suspension: while the dispute runs, missing the voluntary payment period opens the enforcement period with surcharges and interest under articles 41.3 and 174.6 LGT.
  • Trusting that a verbal resignation is enough. Article 43.1 LGT also reaches the de facto director, and with no documentary trace the removal simply does not exist.

The law that applies

  • Art. 41 LGT. Defines tax liability, presumes it to be subsidiary unless a statute says otherwise, excludes penalties save for exceptions, governs the reduction for acceptance and its loss on appeal, and requires an administrative decision after a prior hearing plus the insolvency of the main debtor before reaching subsidiary liable persons. BOE-A-2003-23186
  • Art. 43.1.a) y b) LGT. Makes subsidiarily liable the directors in law or in fact of companies that committed infringements, where they failed to do what fell to them, consented to non-compliance or adopted resolutions enabling it, with liability extending to penalties; and the directors of companies that ceased trading, for obligations accrued and outstanding at cessation. BOE-A-2003-23186
  • Art. 174 LGT. Governs the liability decision: it may be issued at any time after the assessment, falls to the collection office, must be notified with the full text of the decision, the ground of liability and the assessments covered, and allows the appeal to challenge both that ground and those assessments, limited by finality as against other taxpayers. BOE-A-2003-23186
  • Art. 235 LGT. Sets one month from the day after notification to lodge the economic-administrative claim, allows a short pleading with or without arguments, addresses it to the office that issued the act, and requires electronic lodging for those obliged to deal with the authorities electronically. BOE-A-2003-23186
  • Art. 46 LJCA. Sets two months for the contencioso-administrativo claim from the day after notification of the express act closing the administrative route, six months where the act is implied, and clarifies that, where a reposición appeal was lodged, time runs from its express decision or from its deemed rejection. BOE-A-1998-16718

Frequently asked questions

Can the penalties imposed on the company also be demanded from me?

It depends on the subparagraph applied. Article 41.4 LGT states that liability does not extend to penalties save for statutory exceptions, and article 43.1.a) LGT is one of them, since it expressly extends the director's liability to penalties. The ground in subparagraph b), covering companies that ceased trading, contains no such express extension. So the first thing to read is which subparagraph the decision invokes.

I resigned before the debt arose, does that help me?

It helps if you can prove it and if you truly stopped running the company. Article 43.1 LGT reaches directors in law and directors in fact, so a registered resignation does not close the case if you kept signing, ordering payments or negotiating with suppliers. The defence combines the date at the register with evidence that afterwards you decided nothing in the company.

The debt was already final for the company, can I still dispute it?

Yes. Article 174.5 LGT allows your appeal to challenge the ground of liability and the assessments covered by that ground. The same provision sets the limit: the outcome will not review assessments that are final as against other taxpayers, only the amount owed by the person appealing. The company's debt is untouched, but the amount demanded from you can indeed be reduced.

Is there a deadline for the tax office to declare me liable?

Article 174.1 LGT states that liability may be declared at any time after the assessment is made or the self-assessment filed, unless a statute provides otherwise. It is therefore not a door that closes by itself after a short while. What is examined in every case is the limitation of the collection action and the validity of the acts said to have interrupted it.

What happens if I do not pay within the period I am given?

Article 174.6 LGT refers to the payment period of article 62.2 LGT and warns that, if the liable person does not pay within it, the debt is collected by enforcement with the enforcement period surcharge. Article 41.3 LGT says the same: once the voluntary period passes without payment, the enforcement period begins with surcharges and interest. Hence the importance of requesting suspension when appealing.
