Complete guide to tax inspections in Spain: procedure, maximum duration (18/27 months), taxpayer rights, inspection reports (agreement, disagreement), penalties, appeals, and statute of limitations.
Tax Inspections: What to Expect and How to Act
Receiving a notice of inspection proceedings from the Spanish Tax Agency (AEAT) causes concern for any taxpayer or business. However, understanding the procedure, deadlines, and legal rights allows you to face the inspection with adequate protections and minimize risks.
This article analyzes the inspection procedure regulated in Arts. 141-159 of Law 58/2003, the General Tax Act (LGT).
What Is a Tax Inspection?
Functions (Art. 141 LGT)
Tax inspection aims to:
- Investigate the factual basis of tax obligations
- Verify the accuracy of filed returns
- Regularize non-compliant tax situations
- Inform taxpayers of their rights and obligations
Scope (Art. 148 LGT)
| Type | Description |
|---|---|
| General | Complete review of the tax and period |
| Partial | Limited to specific elements |
Starting the Procedure
Notice of Commencement
The notice must identify the taxpayer, the taxes and periods under review, the scope of proceedings, expected duration, and documentation to be provided.
Key Effect: Statute of Limitations Interruption
The notice interrupts the limitation period for the Administration's right to assess the tax debt (Art. 68.1 LGT). The general limitation period is 4 years (Art. 66 LGT).
Maximum Duration (Art. 150 LGT)
| Scenario | Maximum Duration |
|---|---|
| General | 18 months from notice |
| Special complexity | 27 months |
Special Complexity Cases
- Annual turnover meeting audit thresholds (currently EUR 5,700,000)
- Tax consolidation group operations
- Related-party transactions (transfer pricing)
- Groups with interests in non-resident entities
Consequences of Exceeding the Deadline
If the Administration exceeds the maximum period without issuing an assessment:
- The limitation period is not considered interrupted
- Proceedings retain their evidential value but lose their interrupting effect
- The taxpayer recovers the limitation period computation
