Tax Authority Revokes NIF from Companies: What It Means and What You Should Do If You Operate with Them

Key data

Hundreds of business entities registered throughout Spain have had their Tax Identification Number (NIF) revoked by the State Tax Administration Agency. The measure, published in the Official State Gazette on September 11, 2026 through the Resolution of September 8, 2026 from the Tax Management Department, takes immediate effect and affects not only the revoked companies, but also any third party that maintains commercial relationships with them.

The risk is not only for directly affected entities. If your company has signed contracts, issued or received invoices, or conducted any economic operation with an entity whose NIF has been revoked, you may be assuming tax contingencies without knowing it.

What does this regulation establish?

The revocation of the NIF is regulated in Article 6.4 of the General Tax Law, as amended by the Anti-fraud Law 11/2021. The Tax Authority is obliged to publish these revocations in the Official State Gazette to guarantee their publicity and enforceability against third parties, which means that no one can claim ignorance after the publication date.

The specific consequences of NIF revocation are as follows:

• The company is disabled from conducting economic operations with full tax validity.
• It cannot perform banking operations with valid tax backing.
• It cannot enter into contracts with full tax effects.
• Operations conducted with these entities may be questioned by the Tax Authority and generate tax contingencies for the counterparty.

The affected entities respond to a common profile: inactive entities, without real activity or with indications of being used for tax fraud or money laundering. Publication in the Official State Gazette converts this list into a public registry for mandatory consultation by any company that wants to protect itself.

There is, however, an exit route: companies with revoked NIF can request NIF rehabilitation if they prove real activity and compliance with their tax obligations to the Tax Authority.

Economic and operational impact

The impact of this resolution goes far beyond directly revoked companies. For any company operating in the Spanish market, the main risk is having conducted operations with one of these entities without knowing it.

As of September 11, 2026, publication in the Official State Gazette means that any subsequent operation with these entities is difficult to defend during an inspection. Due diligence ceases to be a recommendation and becomes a practical obligation.

Who does it affect?

• Business entities with revoked NIF: are disabled from operating with full tax validity as of September 11, 2026.
• Partners and administrators of affected entities: must assess their liability and NIF rehabilitation options.
• Creditors of revoked entities: their credits may be compromised in terms of tax treatment.
• Suppliers and customers that have operated with these entities: risk of tax contingencies in VAT and Corporate Income Tax.
• Financial institutions that maintain accounts or products with these entities: obligation to exercise extreme diligence.
• Tax advisors and accounting firms that manage the accounting of companies with commercial relationships with affected entities.

Practical example

Imagine that your company contracted consulting services from a business entity—let's say "Integral Services XYZ, S.L."—for an amount of 30,000 euros plus VAT during 2026. You deducted the VAT paid (6,300 euros) and computed the expense in your Corporate Income Tax.

If that entity appears in the resolution published on September 11, 2026 with the NIF revoked, the Tax Authority may question:

• The deductibility of the 6,300 euros of VAT paid, considering that the operation lacks full tax validity.
• The deductibility of the 30,000 euros expense in Corporate Income Tax, if it is understood that the entity had no real activity.
• The possible simulation of the operation, with the resulting sanctioning consequences.

The key is to act before an inspection arrives: review the list published in the Official State Gazette, identify if any supplier or customer is included, and document the economic reality of the operations conducted.

What should companies do now?

1. Consult the list published in the Official State Gazette (Resolution of September 8, 2026, BOE-A-2026-19038) to verify if any of your suppliers, customers or business partners have their NIF revoked.
2. Review the operations conducted with identified entities: invoices issued and received, contracts in force and pending payments.
3. Document the economic reality of operations with these entities: signed contracts, delivery notes, emails, evidence of actual service provision or goods delivery.
4. Suspend any new operations with entities whose NIF has been revoked until they prove NIF rehabilitation to the AEAT.
5. Consult with your tax advisor to assess the risk of operations already conducted and, if appropriate, regularize the situation before a possible inspection.
6. If your company is affected by the revocation: initiate the NIF rehabilitation process with the Tax Authority, proving real activity and compliance with tax obligations.
