What should you do if the Spanish Tax Inspection arrives at your business without warning?
If the Spanish Tax Inspection arrives at your business without prior notice, do not improvise. Verify the identity of the inspecting officers, notify the company’s legal representative and tax adviser immediately, distinguish areas open to the public from restricted premises, and do not permit entry, searches or forensic imaging of computer systems unless an authorised representative is present, the inspectors hold an adequate court order where required, and legal advice has been obtained without delay.
Can the Spanish Tax Inspection visit a business without prior notice?
Yes. The Spanish Tax Inspection may attend a taxpayer’s business premises without prior notification whenever this is considered appropriate for the effective conduct of its inspection activities. Article 177(2) of Royal Decree 1065/2007 of 27 July, approving the General Regulations governing Tax Management and Inspection Procedures and the implementation of the common rules applicable to tax procedures (hereinafter, the RGAT), expressly provides for this possibility.
The absence of prior notice does not invalidate the inspection. However, neither does it deprive the company of its legal rights.
Article 142(1) of Law 58/2003 of 17 December, the General Taxation Act (Ley General Tributaria, hereinafter the LGT), empowers the Tax Inspection to examine accounting records, books, invoices, supporting documentation, correspondence of tax relevance, databases, software, registers and electronic files relating to economic activities.
These are extensive investigative powers.
They are not unlimited.
Where the inspection concerns premises protected as constitutionally protected premises (domicilio constitucionalmente protegido), Article 113 of the LGT applies: entry requires either the taxpayer’s consent or prior judicial authorisation.
Which areas are protected during a Tax Inspection?
Not every part of a company’s premises enjoys the same level of legal protection.
A reception area, retail premises open to the public or an operational warehouse are not equivalent to the managing director’s office, the boardroom, the internal accounting department, confidential archives or the server room.
Article 18(2) of the Spanish Constitution provides that premises protected by constitutional law are inviolable and that no entry or search may take place without the occupant’s consent or a judicial warrant, except in cases of flagrante delicto.
In Constitutional Court Judgment (STC) 69/1999, the Constitutional Court recognised that this protection may also extend to legal persons. Although companies do not enjoy the same degree of privacy as natural persons, they are nevertheless entitled to protection in respect of areas reserved for the management of their business and the safekeeping of confidential corporate documentation.
Article 554(4) of the Criminal Procedure Act (Ley de Enjuiciamiento Criminal), approved by Royal Decree of 14 September 1882, provides useful guidance. In the case of legal entities, protected premises include the company’s management centre together with those areas where documents and other confidential records relating to its internal affairs are kept and are not intended to be accessible to third parties.
Is mere suspicion sufficient to justify a Tax Inspection?
No.
An entry into constitutionally protected premises cannot become a fishing expedition.
In Supreme Court Judgment (STS) 1231/2020 of 1 October, commonly referred to as the Taberna La Montillana case, the Supreme Court held that the Tax Administration cannot justify entry solely because a company’s declared profit margins fall below the sector average. Statistical discrepancies may justify further enquiries, but they do not, in themselves, justify intrusion into constitutionally protected premises
This principle was reinforced by Supreme Court Judgment (STS) 1163/2021 of 23 September, which held that judges cannot merely endorse administrative applications through generic reasoning. They must act as genuine guardians of the fundamental right concerned by assessing whether the proposed measure is appropriate, necessary and proportionate.
If the Tax Administration seeks judicial authorisation to enter business premises, it must provide proper reasons. If a judge grants authorisation, the judge must exercise effective judicial scrutiny.
Who may consent to the Tax Inspection entering the premises?
Consent must be given by a person capable of legally binding the company, such as a director, managing director, attorney-in-fact or another duly authorised representative with actual authority to permit entry.
Consent must be freely given, informed and specific.
Furthermore, Article 172 of the RGAT allows such consent to be withdrawn at any stage during the inspection, without prejudice to any interim protective measures that may subsequently be adopted under Article 146 of the LGT.
In Constitutional Court Judgment (STC) 54/2015 of 16 March, the Constitutional Court held that the Tax Administration must inform the taxpayer beforehand of their rights and of the nature and scope of the proposed inspection.
More recent Supreme Court judgments of 12, 17 and 25 March 2026 have reinforced this principle. The Court held that merely providing the information leaflet usually attached to the notice commencing a tax inspection procedure is not, by itself, sufficient to discharge the Administration’s duty to inform.
The company must be clearly informed that it is entitled to refuse consent to entry and that any consent already given may be withdrawn at any time.
It must also be informed of an equally important point: refusing consent does not automatically constitute obstruction, nor does it automatically give rise to penalties. The ordinary consequence is simply that the Tax Administration may apply for judicial authorisation, which the court will either grant or refuse.
Accordingly, where consent is requested, the crucial issue is not merely who gives it, but also what information that person received before doing so. Without adequate prior information, the legal validity of the consent is significantly undermined.
What must a court order authorising a Tax Inspection contain?
A judicial warrant authorising entry must clearly identify the company concerned, the taxes under investigation, the relevant tax periods, the premises covered by the authorisation, the purpose of the inspection and the reasons why the measure is considered necessary.
Article 113 of the General Taxation Act (LGT) requires the application for judicial authorisation to set out the purpose of the entry, together with a reasoned explanation demonstrating its necessity and proportionality. Following the enactment of Law 11/2021 of 9 July on measures to prevent and combat tax fraud, judicial authorisation may now be sought even before the formal commencement of inspection proceedings, provided that the decision requesting entry identifies the taxpayer concerned together with the taxes and tax periods to be examined.
The reform has made the procedural timing more flexible.
It has not diminished the substantive safeguards protecting taxpayers’ fundamental rights.
In Constitutional Court Judgment (STC) 8/2000 of 17 January, the Constitutional Court emphasised that proper reasoning is an essential element of any judicial decision authorising entry. A generic warrant, lacking a genuine definition of the purpose of the inspection, the premises concerned or the scope of the authorisation, remains vulnerable to subsequent legal challenge.
The legal debate is, moreover, still ongoing. By means of an Order dated 5 March 2026, the Spanish Supreme Court has granted leave to appeal in a case requiring it to determine whether the current statutory framework governing entries by the Tax Inspection satisfies the “quality of law” standard established by the case law of the European Court of Human Rights under Article 8 of the European Convention on Human Rights.
The issue is of considerable constitutional importance.
The Court will have to determine whether the legal framework currently contained in Articles 113 and 142 of the LGT provides an adequate legal basis for a measure that directly interferes with the fundamental right to the inviolability of protected premises. It will also clarify the legal consequences arising from access to third-party data obtained during such inspections.
The profession now awaits the Supreme Court’s judgment.
May the Tax Inspection copy computers, emails or cloud-based files?
The Tax Inspection is entitled to access electronically stored information that is relevant for tax purposes.
It is not entitled to do so without legal limits.
Article 142(1) of the LGT expressly includes databases, software, registers and electronic records relating to business activities within the scope of the Inspection’s investigative powers. Likewise, Article 171 of the RGAT authorises inspectors to obtain copies of the data, accounting records or documents examined during the inspection.
The principal legal issue concerns large-scale forensic imaging and bulk copying of digital information.
In Supreme Court Judgment (STS) 1122/2024 of 25 June, the Supreme Court significantly strengthened digital procedural safeguards. It held that where the Tax Inspection seeks access to computer equipment or digital repositories located within constitutionally protected premises, or remotely accessible from those premises, the judicial warrant must contain specific reasoning justifying the digital search.
Authorising physical entry into the premises together with a generic reference to “computer equipment” is not sufficient. The judge must specifically assess the necessity of the forensic imaging process, the nature of the data involved, its temporal scope, its connection with the taxes under investigation and the potential impact on the company’s business activities.

How should a company respond to an unannounced Tax Inspection?
A company should activate its internal response protocol immediately.
The inspecting officers’ identities should be verified, a copy of the inspection order or judicial warrant should be requested, and the company’s director or authorised representative, together with its tax adviser, should be informed without delay.
Until a person with the necessary authority is present, no employee should consent to entry, searches, copying of documents or forensic imaging of computer systems.
Throughout the inspection, the company should ensure that the inspectors do not exceed the scope authorised by law or by the judicial warrant. A detailed record should be kept of the areas visited, the documents reviewed and any information copied during the inspection.
Employees may cooperate by locating files or providing access to computer systems.
They should not, however, be subjected to impromptu questioning.
In Supreme Court Judgment (STS) 1173/2024 of 2 July 2024, the Supreme Court held that interviews conducted without prior notice during the course of a search of protected premises were incompatible with the taxpayer’s right of defence.
At the conclusion of the inspection, the official inspection record (diligencia) should be reviewed with particular care. This document records the facts established and the investigative steps taken during the inspection. Pursuant to Articles 99(7) and 107 of the LGT, it constitutes evidence of those facts unless rebutted by evidence to the contrary.

Pursuant to Articles 99(7) and 107 of the LGT, it constitutes evidence of those facts unless rebutted by evidence to the contrary.
If the Tax Inspection acts beyond the limits of the judicial authorisation or otherwise infringes the company’s procedural guarantees, such irregularities may subsequently constitute substantial grounds for challenging both the inspection procedure and any tax assessment issued as a consequence.
For this reason, it is essential that any excesses committed during the inspection are recorded in the official inspection record from the outset, as this will provide valuable evidence both during the administrative proceedings and, where necessary, before the courts.
FAQ about Tax Inspections at business premises
Can the Spanish Tax Inspection enter my business premises without prior notice?
Yes. Under Article 177(2) of the General Regulations governing Tax Management and Inspection Procedures (RGAT), the Tax Inspection may attend a taxpayer’s business premises without prior notification where this is considered appropriate for the effective conduct of its inspection activities.However, the absence of prior notice does not deprive the company of its procedural rights or constitutional guarantees.
Can the Tax Inspection enter any part of my business premises?
No. Areas that are open to the public, such as reception areas, retail premises or operational warehouses, do not enjoy the same level of constitutional protection as private areas used for the management of the business. Offices occupied by senior management, boardrooms, internal accounting departments, confidential archives and server rooms may constitute constitutionally protected premises, meaning that entry generally requires either the taxpayer’s valid consent or prior judicial authorisation.
Which areas of a company’s premises may be regarded as constitutionally protected premises?
Certain restricted areas where the company conducts its management activities or keeps confidential internal documentation may qualify as constitutionally protected premises. These may include the managing director’s office, the boardroom, the accounting department, confidential archives or the server room. By contrast, a reception area, retail premises open to the public or certain operational areas do not necessarily enjoy the same level of constitutional protection.
Who is entitled to authorise the Tax Inspection to enter the premises?
Only a person with authority to legally bind the company may validly consent to entry. This will normally include a director, managing director, attorney-in-fact or another duly authorised representative. Consent must be freely given, informed and specific. It may also be withdrawn during the course of the inspection, subject to any precautionary measures that the Tax Administration may subsequently adopt in accordance with the law.
What requirements must the company’s consent satisfy?
The company’s consent must be freely given, informed, explicit and specific. Before giving consent, the company must be informed of the purpose and scope of the inspection, as well as of its right to refuse entry or to withdraw its consent at any stage of the inspection.
May a company refuse to allow the Tax Inspection to enter its premises?
Yes. Refusing to give consent does not automatically result in a penalty, nor does it necessarily amount to obstruction. Where consent is refused, the Tax Administration may apply for judicial authorisation. It is then for the court to determine whether the proposed entry is appropriate, necessary and proportiona
Can consent be withdrawn once the inspection has begun?
Yes. Consent may be withdrawn at any stage of the inspection. However, the Tax Inspection may adopt any precautionary measures provided for by law to prevent the concealment, destruction or alteration of evidence.
¿Can the Tax Administration enter a company’s premises solely on the basis of suspicion?
No. Not every suspicion is sufficient. A statistical discrepancy, profit margins below the industry average or a general suspicion may justify the commencement of a tax investigation, but they are not, in themselves, sufficient to authorise entry into constitutionally protected premises. The Tax Administration must present specific evidence giving rise to a reasonable suspicion and demonstrate that the proposed measure is appropriate, necessary and proportionate.
