Over 100 companies resume operations with full tax and commercial guarantees as of October 21, 2026. The Tax Agency has published in the Official Gazette the rehabilitation of their tax identification numbers (NIF), an essential step for that recovery to take effect against third parties and before provincial commercial registries.
The resolution is based on article 6.4 of the General Tax Law, in its current wording following the amendment introduced by Law 11/2021 on measures to prevent and combat tax fraud. The affected NIFs had been revoked at different times between 2014 and 2026, and the rehabilitation agreements are concentrated in September and October 2026.
What does this regulation establish?
The resolution formally publishes the rehabilitation of the NIFs of over 100 commercial entities. This publication in the Official Gazette is not an optional procedure: it is the legal requirement that allows rehabilitation to take effect against third parties (customers, suppliers, financial entities) and before provincial commercial registries.
To understand the scope, it is worth recalling what having a revoked NIF entails:
- The company cannot issue valid invoices or deduct expenses for tax purposes.
- It is excluded from contracting with the Public Administration.
- It cannot register acts in public registries (capital increases, administrator changes, property transfers, etc.).
- Financial entities may block or restrict their accounts and operations.
Rehabilitation reverses all these restrictions. However, the company must have previously regularized its situation with the AEAT: publication in the Official Gazette is the final step, not the first.
The sectors represented among the rehabilitated entities are very diverse:
| Sector |
|---|
| Real Estate |
| Construction |
| Hospitality |
| Transport |
| Technology |
Economic and operational impact
For rehabilitated companies, the impact is immediate and of great operational significance. Recovering the NIF means being able to invoice again with full legal validity, which in practice amounts to reactivating commercial activity completely.
From an operational standpoint, the most relevant effects are:
- Invoicing: Invoices issued with a revoked NIF lack tax validity. From October 21, 2026, rehabilitated entities can issue invoices with full effectiveness.
- Commercial registry: They can register corporate acts (appointments, increases, transfers) that were blocked during the revocation period.
- Public procurement: They recover the ability to bid and contract with Public Administrations.
- Banking relationships: Financial entities can normalize operations that had been restricted due to NIF revocation.
For third parties operating with these companies (customers, suppliers, partners), publication in the Official Gazette is official proof that the NIF is valid again. It is advisable to verify the NIF status of any counterparty before formalizing contracts or accepting invoices.
Who does it affect?
- Companies with rehabilitated NIF: The over 100 commercial entities included in the resolution, which recover their full tax and commercial operability from October 21, 2026.
- Companies with currently revoked NIF: Those that have not yet regularized their situation must act as soon as possible to avoid total blockage of their activity.
- Customers and suppliers of affected companies: They must verify the validity of their counterparties' NIF before accepting invoices or signing contracts.
- Tax advisors and managers: They must review whether any of their clients appear in the resolution or have a NIF at risk of revocation.
- Provincial commercial registries: They must update their information following publication in the Official Gazette to admit registrations of rehabilitated entities.
- Financial entities: They can normalize operations with companies whose NIF has been rehabilitated.
Practical example
A real estate company—one of the sectors represented in the resolution—had its NIF revoked since 2021. During that period, it could not register the transfer of a property in the Commercial Registry or issue valid invoices to its customers. Any invoice issued during that period lacked tax validity for the recipient.
After regularizing its situation with the AEAT and obtaining the rehabilitation agreement in September or October 2026, the publication of the resolution in the Official Gazette on October 21, 2026 allows it to:
- Issue invoices with full tax validity from that date.
- Submit documentation to the Commercial Registry to register pending corporate acts.
- Prove to customers, suppliers, and financial entities that its NIF is valid again, providing a reference to the resolution published in the Official Gazette (BOE-A-2026-21931).
A supplier that had received invoices from this company during the revocation period should review with their tax advisor the treatment of those invoices, as their validity is questionable.
What should companies do now?
- If your company appears in the resolution: Verify the publication in the Official Gazette (reference BOE-A-2026-21931) and inform your customers, suppliers, and financial entity that your NIF has been rehabilitated effective October 21, 2026.
- If you have a revoked NIF and are not on the list: Contact the AEAT to regularize your situation as soon as possible. Each day with a revoked NIF means inability to invoice and operate with full validity.
- If you are a supplier or customer of any of the affected companies: Check the AEAT census or the Official Gazette itself to confirm the validity of your counterparty's NIF before accepting invoices or signing new contracts.
- If you are a tax advisor or manager: Review the complete list of the resolution to identify if any client appears in it, and advise them on the treatment of invoices issued or received during the revocation period.
- For pending registry registrations: Rehabilitated entities can immediately submit documentation to the corresponding provincial Commercial Registry, providing the reference of the Official Gazette publication as proof of rehabilitation.
Frequently asked questions
What are the consequences of having a revoked NIF?
With a revoked NIF, a company cannot issue invoices with tax validity, cannot contract with the Public Administration, and cannot register acts in public registries (such as the Commercial Registry). Financial entities can also restrict their operations. Revocation effectively means total blockage of the company's commercial and tax activity.
How do I know if my company or a counterparty has a revoked or rehabilitated NIF?
You can check the NIF status of any entity through the AEAT's electronic office. Additionally, rehabilitations are officially published in the Official Gazette: the resolution of October 14, 2026 (reference BOE-A-2026-21931), published on October 21, 2026, lists the rehabilitation of over 100 commercial entities whose NIFs had been revoked between 2014 and 2026.
When does the NIF rehabilitation published in the Official Gazette on October 21, 2026 take effect?
The rehabilitation takes effect against third parties and before provincial commercial registries from the date of publication in the Official Gazette, that is, October 21, 2026. Publication in the Official Gazette is the legal requirement established in article 6.4 of the General Tax Law (as amended by Law 11/2021) for rehabilitation to be enforceable against third parties.
What steps must be taken to rehabilitate a revoked NIF?
The company must regularize its situation with the AEAT (file pending returns, settle tax debts, etc.) and formally request rehabilitation. Once the AEAT issues the rehabilitation agreement, it is published in the Official Gazette so it takes effect against third parties. The agreements included in the October 2026 resolution were concentrated in September and October 2026.
Are invoices issued during the period when the NIF was revoked valid?
Invoices issued with a revoked NIF lack tax validity. Both the issuer and the recipient must review with their tax advisor the treatment of those invoices, especially regarding VAT deduction and expense allocation in Corporate Income Tax. Rehabilitation does not automatically validate invoices issued during the revocation period.
