Tax Authority Revokes NIF from Over 100 Companies: What It Means in 2026

Key data

Over 100 companies have lost their operational capacity overnight. The AEAT has published in the Official Gazette of June 10, 2026 the revocation of their tax identification numbers, leaving them disabled for any economic activity. The measure is based on article 6.4 of the General Tax Law, modified by the Anti-fraud Law 11/2021, which strengthens the Tax Authority's tools to combat structured fraud through shell companies.

The profile of those affected is revealing: the majority are Limited Liability Companies (LLC), many of them registered "in formation", concentrated mainly in Las Palmas and Madrid. This pattern points to fraudulent use or deliberate abandonment of these business structures.

What does this regulation establish?

The resolution publishes the list of companies whose NIF has been revoked by the AEAT. This action has immediate and very concrete consequences for affected companies:

• Disablement to operate: the company cannot conduct economic operations with fiscal validity.
• Banking access closure: it cannot open new bank accounts or operate with existing ones in a standard manner.
• Impossibility of signing contracts: any contract signed with a revoked NIF lacks valid fiscal backing.
• Collective notification by Official Gazette: publication in the Official Gazette has notification effects for all affected parties, without need for individual communication.

The legal basis is article 6.4 of the General Tax Law, as amended by Law 11/2021, on measures to prevent and combat tax fraud. This law expanded the causes and procedure for NIF revocation, precisely to facilitate action against organized fraud schemes that use shell companies or abandoned entities.

The fact that many of those affected are "in formation" is especially significant: it suggests these are structures created but never legitimately operational, possibly used for fraudulent operations or simply abandoned after formation.

Economic and operational impact

The impact is not limited to companies with revoked NIF. The risk extends to any third party that has operated or is operating with them:

• Invoices issued or received: invoices issued by a company with revoked NIF may be rejected by the Tax Authority, implying loss of VAT deduction for the recipient.
• Existing contracts: contracts signed with these companies may be in a situation of legal uncertainty, especially if they involve future payments or pending deliveries.
• Risk of joint liability: in certain cases, knowingly operating with a company in irregular fiscal situation may generate liabilities for the third party.
• Creditors: those with pending debts from these companies will see their position even more compromised, as NIF revocation usually precedes or accompanies situations of insolvency or de facto disappearance.

For the Tax Authority, this resolution is a tool to combat structured tax fraud. Collective publication in the Official Gazette allows efficient action against a large number of companies in a single resolution, without need for individualized procedures for each one.

Who does it affect?

• Companies with revoked NIF: are immediately disabled from any economic, banking or contractual operation.
• Partners and administrators of affected companies: may face liabilities arising from the company's fiscal situation.
• Creditors and suppliers with pending debts against these companies: their position is significantly weakened.
• Customers and contractors who have received invoices from these companies: risk of loss of tax deductions.
• Financial entities with which these companies operate: required to verify NIF status before executing operations.
• Any company or professional negotiating or about to sign a contract with any of the affected parties.

Practical example

Imagine your company, a mid-sized construction firm based in Madrid, has subcontracted work to an LLC also registered in Madrid. That LLC appears in the resolution published on June 10, 2026 with a revoked NIF.

The immediate consequences for your company are:

• The invoices you have received from that LLC may be questioned by the Tax Authority, putting at risk the VAT deduction.
• If you have pending payments, you should not execute them without first verifying the situation and consulting with your tax advisor, as you could be financing an irregular structure.
• If you have pending collections from that LLC, the NIF revocation is a maximum alert signal: activate collection mechanisms as soon as possible, as the company may be in process of de facto disappearance.
• Any ongoing contract with that company should be reviewed by a lawyer to assess its validity and resolution options.

This scenario is perfectly applicable to companies in Las Palmas, where the concentration of affected parties is also very high according to the resolution.

What should companies do now?

1. Verify the NIF of your regular suppliers and customers in the AEAT census, especially if they are recently formed LLCs or based in Las Palmas or Madrid. The consultation is free and accessible on the AEAT's electronic office.
2. Review invoices received in recent months from any supplier that may be among those affected. Identify if any correspond to companies "in formation" or with irregular activity.
3. Halt any pending payments to companies whose NIF is being verified until confirming their fiscal situation.
4. Consult with your tax advisor if you have received invoices from any of the affected companies, to assess the risk of loss of VAT and corporate income tax deductions.
5. Activate collection claims if you have pending debts with any of these companies: NIF revocation is an alert signal that advises acting urgently.
6. Include fiscal verification clauses in your future contracts, requiring the counterparty to prove the validity of their NIF before signing and at each renewal.
