The Spanish Tax Office (Agencia Estatal de Administración Tributaria – AEAT), commonly referred to as Hacienda, is responsible for managing the national tax system in Spain. One of its main roles is to ensure that taxpayers comply with their tax obligations. When this does not happen—whether due to omissions, improper payments, or delays—the AEAT can impose financial penalties. Below, we outline the most common types of sanctions and their consequences:
1. Infractions for failure to file tax returns
Late filing without prior notice from the tax authority
When a taxpayer files a return late without having received a prior request from the AEAT, it is not considered a formal penalty, and only surcharges are applied:
- A fixed surcharge of 1% plus an additional 1% for each full month of delay, up to a maximum of 15% when reaching 12 months of delay.
- If the delay exceeds these 12 months, late payment interest is added in addition to the 15% surcharge.
Late filing with prior notice
In this case, the AEAT considers the existence of a prior infraction, and usually imposes a financial penalty:
- A fine ranging from 50% to 150% of the tax debt, depending on the severity of the non-compliance.
- A 30% reduction applies if the taxpayer accepts the penalty without appeal, and an additional 40% reduction if payment is made within the voluntary period.
2. Infractions for failure to pay taxes
Unlike the previous section, where the issue is the late or missing submission of tax declarations, this point refers specifically to situations where the tax return has been filed correctly or situations in which the Spanish Tax Office has determined that the taxpayer has a tax debt, but the taxpayer fails to make the corresponding payment within the legal deadline.
- If no formal payment demand has been issued by the AEAT: The surcharge is known as an executive surcharge (“recargo ejecutivo”) and is of 5%, the taxpayer pays voluntarily before receiving any notification from the Tax Office.
- If the taxpayer has received an enforcement order (“apremio”): A reduced enforcement surcharge (“recargo apremio reducido”) of 10% applies, provided the full amount due (plus the surcharge) is paid within the specified period. If this condition is not met, a standard enforcement surcharge (“recargo de apremio ordinario”) of 20% will be applied, in addition to late payment interest and any administrative enforcement costs incurred during the collection process.
In summary, the key difference from the previous point is that there, the tax return has already been filed (or the Tax Office has already assessed the debt) but payment was not made on time.
3. Infractions for inaccurate or false declarations
When a taxpayer files a return with incorrect or false information with the intention of reducing the tax amount due, the AEAT may classify it as:
- Minor, serious, or very serious, depending on financial impact and intent.
- Penalties range from 50% to 150% of the defrauded amount.
4. Other relevant sanctions
- Failure to issue invoices or issuing them incorrectly can lead to fines of up to 2% of annual turnover.
- Obstructing a tax inspection can result in fines exceeding 600,000€ if classified as a very serious infraction.
5. Can penalties be avoided or reduced?
Yes. The AEAT offers mechanisms to reduce penalties, provided the taxpayer does not appeal, pays within the established deadline, or cooperates during the inspection process.
Conclusion
Sanctions imposed by the AEAT for late filing or payment of taxes can represent a significant cost for individuals and businesses. The key to avoiding surcharges and penalties is to comply fully with tax obligations and, in case of errors, to rectify them as soon as possible. It is advisable to consult a tax advisor when in doubt, as they can guide taxpayers on how to act and minimize the risk of inspection.
