If you have received a notice initiating a Tax Agency inspection, our first recommendation is not to respond off the cuff. Before submitting documents or making statements, it is advisable to identify exactly which tax, tax years and transactions the Spanish Tax Agency wishes to review, the scope of its actions and the deadline given to respond to the first request.
At Barcelona Tributario, we analyse tax inspections from the very first notice. We organise the case file, determine what the AEAT is actually requesting, review the documentation before it is submitted and build a consistent strategy from the outset through to the inspection report, assessment and, if necessary, the economic-administrative appeal or court proceedings.
An inspection does not mean that the Tax Agency is right or that a penalty will necessarily follow. It does mean that this is a procedure with extensive investigative powers and potentially significant consequences, particularly where several tax years, companies, related-party transactions, international income or substantial assets are being reviewed.
If the Tax Agency opens an inspection, these are the first steps we recommend
1. Download and retain the full notice and all its attachments.
2. Identify the taxes, tax years, general or partial scope and documents requested.
3. Record the exact date of notification and all deadlines.
4. Do not destroy, alter or conceal documentation.
5. Do not submit documents outside the request without first assessing their relevance.
6. Centralise communication with the AEAT and keep a record of every submission.
7. If substantial amounts, international transactions, complex corporate structures or potential penalty or criminal implications are involved, seek specialist tax representation from the outset.
What it means when the Tax Agency has opened a tax inspection
The inspection procedure is governed mainly by Law 58/2003, the General Tax Law, and by the Regulations approved by Royal Decree 1065/2007.
Receiving a tax inspection notice can be unsettling, but acting promptly makes a difference. Our tax lawyers will assess your case with no obligation and tell you exactly what steps to take from the outset.
An inspection may verify the truthfulness and accuracy of tax returns, investigate undeclared facts, obtain tax-relevant information, verify valuations and review compliance with the requirements for tax benefits or regimes.
General or partial inspection
One issue we review immediately is the scope. Actions may be general or partial. In a partial inspection, the Administration defines the elements of the tax obligation it intends to review. This definition matters because it allows us to monitor whether the actions subsequently remain within the notified scope or whether it is formally amended.
A tax inspection and a limited verification are not the same
A tax inspection should not be confused with a limited verification. A limited verification has more restricted powers. However, since the 2023 reform, the Administration may also examine commercial accounting within the limits set out in Article 136 of the General Tax Law, mainly to compare it with information already held or obtained during the procedure.
For this reason, we avoid relying on the former rule that “in a limited verification, the Tax Agency can never look at the accounts”: that statement would now be incorrect.
What we do when the first inspection notice arrives
1. We verify what is being reviewed
- Tax or taxes affected.
- Tax years or periods.
- General or partial scope.
- Authority conducting the procedure.
- Documentation requested.
- Place and method of attendance.
- Response deadline.
- Duration of the procedure notified by the AEAT.
2. We reconstruct the case file before responding
Depending on the matter, we review tax returns, accounts, invoices, contracts, deeds, corporate transactions, relevant financial movements, tax reports, related-party transactions, transfer pricing documentation, tax residence and international transactions.
3. We submit what is required, but not indiscriminately
The taxpayer has duties of cooperation with the Inspection and must comply with lawfully issued requests. That does not mean it is advisable to voluntarily provide entire folders or information that has not been requested without first analysing its connection with the subject matter of the inspection.
Our rule is simple: comply with the request accurately, traceably and with context.
We also take into account that the General Tax Law recognises the right not to provide documents that are not required under tax legislation or that have already been submitted and are held by the Administration, on the terms provided by law.
4. We review every record of proceedings
Records of proceedings document facts, statements, documentation submitted and actions taken. Before confirming their content, we check that they faithfully reflect what occurred and, where appropriate, record observations or qualifications.
Documentation that should not be destroyed or altered
Once the procedure has begun, all potentially relevant documentation must be preserved. We do not recommend deleting emails, altering files, recreating invoices, modifying accounts or destroying documents.
The obligation to retain documentation should not simply be reduced to “four years”. The general tax limitation period is four years, but there are specific rules and commercial or tax documents that may need to be retained for longer periods; moreover, certain tax bases, amounts or deductions may be subject to review during special time limits.
Taxpayer rights during an inspection
Right to know the nature and scope
Article 34 of the General Tax Law recognises, among others, the right to be informed at the outset of the nature and scope of verification or inspection actions and of the rights and obligations during the procedure.
Right to know the status of the procedure
We may request information on the status of the procedure and identify the authorities and staff responsible for handling it.
Right to submit documentation and make submissions
The taxpayer may submit documentation considered relevant to the resolution of the procedure and make submissions at the stages provided for.
Right to obtain copies of the case file at the times provided by law
The General Tax Law recognises the right to obtain copies of the documents forming part of the case file, but we do not present this right as unrestricted access “at any time”. The legislation specifically regulates obtaining copies and disclosure of the case file.
Right to act through a representative
We can act as representatives on the terms permitted by law and centralise dealings with the Inspection, without prejudice to the fact that it may exceptionally require the taxpayer’s personal attendance with stated reasons.
Can the Tax Agency enter a business or home?
Business premises, offices and establishments
The Inspection may attend businesses, offices, premises, facilities or warehouses even without prior notice. To access certain locations where business activities are carried out, Article 142 of the General Tax Law requires an entry order from the relevant administrative authority, unless the owner or custodian gives consent.
Constitutionally protected home
Where the intended place of entry is a constitutionally protected home, the situation is different. In that case, the Administration requires the holder’s consent or the corresponding judicial authorisation under Article 113 of the General Tax Law.
We do not recommend responding automatically by either “always allowing entry” or “always refusing entry”. If an unannounced visit takes place, the correct approach is to identify the officials, verify their legal authority and obtain immediate advice on the specific scope of the action.
An unannounced visit from the Tax Agency requires particular caution. The distinction between business premises and a constitutionally protected space may be legally decisive.
How long can a Tax Agency inspection last?
| Time limit | Situation |
|---|---|
| 18 months | General time limit for the inspection procedure. |
| 27 months | Where one of the statutory circumstances applies, including certain annual turnover levels, membership of certain tax groups or verification of the Top-up Tax. |
The calculation may be affected by legally provided periods of suspension or extensions.
Exceeding the time limit does not mean the inspection lapses
Failure to comply with the maximum time limit does not cause the inspection procedure to lapse. The inspection may continue until it is concluded.
However, exceeding the time limit has important legal effects: among others, actions carried out during the period beyond the deadline do not produce certain interruption effects on the limitation period under Article 150.6, and late-payment interest ceases to accrue from the breach until the procedure ends.
Agreement report, disagreement report and agreed report
Agreement report
This arises where the taxpayer agrees with the proposed adjustment. In penalty matters, the General Tax Law provides for a 30% reduction for agreement under Article 188.
There may also be an additional reduction of 40% of the resulting penalty where the legal requirements for payment and no appeal or claim are met.
Disagreement report
Where we do not accept the proposal, the report records the disagreement and the corresponding stage for submissions opens before the assessment is issued.
Agreed report
The agreed report is reserved for the cases set out in Article 155 of the General Tax Law and requires specific conditions. The current penalty reduction for agreed reports is 65%, not 50%.
Before accepting any report, we calculate not only the immediate reduction but also the strength of the available arguments, the total liability, interest, penalty and the legal cost of giving up certain appeal routes.
When there may be a risk of tax crime
Article 305 of the Criminal Code provides for an offence against the Public Treasury where, under the terms of the criminal provision, a tax amount exceeding €120,000 is defrauded.
Every day without specialist advice can make your situation with the Tax Agency more difficult. Contact Barcelona Tributario and place your tax defence in the hands of experts who understand every detail of the inspection procedure.
That threshold does not mean that every adjustment exceeding €120,000 is automatically a crime. Criminal liability requires an analysis of the other elements of the offence, including the existence of intentional fraudulent conduct.
The right against self-incrimination does not remove tax cooperation obligations
Where potential penalty or criminal consequences arise, we analyse particularly carefully what information is requested and in what context. We do not recommend independently adopting a strategy of absolute silence during the tax procedure: the General Tax Law imposes cooperation obligations, and the scope of the right against self-incrimination in tax and penalty proceedings is legally complex.
If we identify a real criminal risk, we coordinate the tax strategy with the appropriate criminal defence from that point onwards.
Inspections involving international transactions and substantial assets
Inspections become particularly complex when they involve tax residence, income or assets in several countries, foreign entities, related-party transactions, transfer pricing, double taxation treaties, Non-Resident Income Tax, the special regime for inbound workers or assets held through corporate structures and international investments.
In these cases, we review the consistency between residence, corporate structures, economic flows, contractual documentation and tax treatment in each relevant jurisdiction.
What appeals are available after a Tax Agency assessment?
Application for reconsideration
As a general rule, against an act that may be subject to an economic-administrative appeal, we may optionally file an application for reconsideration with the same body that issued it. The general time limit is one month.
Economic-administrative appeal
We may also use the economic-administrative route. Where the act comes from regional AEAT bodies in Catalonia, jurisdiction normally lies with the Regional Economic-Administrative Tribunal of Catalonia (TEAR), at first and final instance or first instance, depending on the jurisdiction and amount rules.
For certain higher-value claims, there is a second instance before the TEAC, and in some cases the legislation allows the appeal to be brought directly before the TEAC at first and final instance.
Judicial review proceedings
Once the economic-administrative route has been exhausted, we may bring judicial review proceedings. We do not state that court jurisdiction depends simply on the amount: the competent court depends, among other factors, on the body whose decision brings the administrative route to an end.
Do you have to pay while appealing?
Filing an appeal or claim does not automatically suspend the assessed tax liability. To suspend enforcement, we will normally need to apply for it and, depending on the route and circumstances, provide a guarantee or show that the legal requirements are met for a suspension without a guarantee or under another arrangement.
Penalties are subject to a different regime
Tax penalties are subject to different suspension rules while being challenged through the administrative route. For this reason, we analyse the tax liability, interest, penalty, guarantees and financial cost of suspension separately.
Mistakes we recommend avoiding during an inspection
Ignoring a notice
Not opening an electronic notice does not prevent it from taking effect. Where there is an obligation to deal electronically with the Administration, notification systems and their dates must be monitored.
Responding without reviewing the scope
Before submitting documentation, we check whether the request is connected with the notified subject matter and scope, and what consequences each document may have.
Providing more information simply “for transparency”
Cooperating does not mean giving up an organised defence. We provide what is required and strategically useful, always within the law.
Signing records of proceedings without reading them
A record of proceedings may contain statements with future relevance. We review its content before confirming it as accurate.
Accepting an agreement solely because of the reduction
A reduction may be financially attractive, but we must first establish whether the adjustment is correct.
Waiting until the assessment to seek a lawyer
A defence is more effective when we can intervene before technical positions are set out in records of proceedings and reports.
AEAT and Agència Tributària de Catalunya inspections
In Barcelona, procedures may involve different tax administrations. The AEAT administers, among others, state taxes such as Personal Income Tax, Corporate Income Tax, VAT and Non-Resident Income Tax.
The Agència Tributària de Catalunya (ATC) exercises powers over certain own and devolved taxes, including matters relating to inheritances and gifts, transfer tax and wealth tax within the applicable allocation of powers.
Where a client has simultaneous procedures before different administrations, we coordinate the strategy to avoid inconsistencies between the information submitted in each case file.

Frequently asked questions about Tax Agency inspections in Barcelona
What should I do if the Tax Agency notifies me of an inspection?
We recommend retaining the complete notice, checking the taxes, tax years, scope and deadlines, and reviewing the documentation before responding. We can analyse the first request and prepare the strategy from the outset.
Not sure whether you should respond, appeal or negotiate with the Tax Agency? We help you understand your rights and make the best decision to protect your assets from the first request.
How long does a Tax Agency inspection last?
The general time limit is 18 months. It may be 27 months where one of the circumstances set out in Article 150 of the General Tax Law applies. There are also circumstances that may suspend or extend the calculation.
If the Tax Agency exceeds 18 months, is the inspection cancelled?
Not automatically. Failure to comply with the time limit does not cause the inspection procedure to lapse, but it does have significant effects on limitation periods and late-payment interest under Article 150.6 of the General Tax Law.
Can the Tax Agency enter my business without notice?
The Inspection may attend businesses and premises without prior notice. The access regime depends on the type of space. Entry into a constitutionally protected home requires consent or judicial authorisation; specific rules under Article 142 of the General Tax Law apply to other premises.
Do I have to provide everything the Tax Agency asks for?
There is a legal duty to cooperate, but every request should be assessed for its content, scope and basis. There are also rights not to provide documents that are not required or have already been submitted, on the terms provided by the General Tax Law.
What reduction applies to a penalty if I sign an agreement report?
The reduction for agreement provided for in Article 188 of the General Tax Law is 30%. A 40% reduction of the remaining penalty may also apply where the legal requirements for payment and no appeal or claim are met.
What reduction currently applies to an agreed report?
The penalty reduction for an agreed report is currently 65%. It is not 50%. Signing requires specific conditions and limits subsequent challenges.
Does a debt above €120,000 mean tax crime?
Not by itself. Article 305 of the Criminal Code uses that threshold within the definition of the offence, but all other required elements must also be present, including intentional fraudulent conduct.
Can I appeal an assessment after an inspection?
Yes, where the act is appealable and there are grounds to do so. We can assess an application for reconsideration or an economic-administrative appeal, normally within one month, and subsequently judicial review proceedings where appropriate.
Does appealing automatically suspend payment?
Not for the assessed tax liability. Suspension must be requested and may require a guarantee depending on the circumstances. Penalties are subject to a different suspension regime while they are challenged administratively.
Can you take on an inspection that has already started?
Yes. We review the initial notice, documentation submitted, records of proceedings, proposals, time-limit calculations and procedural position to determine which actions remain available and how to structure the defence from that point onwards.
