Late filing penalties for Spanish property taxes: recargo de extemporaneidad, sanciones and what non-resident owners pay (2026)

Miss a Spanish tax deadline and the cost depends on one thing: whether you file voluntarily before the tax authority comes to you, or whether the Agencia Tributaria (AEAT) discovers the gap first. Spain’s Ley General Tributaria (Ley 58/2003, the LGT) draws a sharp line between these two paths. Voluntary late filing triggers the recargo de extemporaneidad, a surcharge of 1 to 15 per cent under Article 27. Being caught by AEAT triggers a sancion, a penalty of 50 to 150 per cent of the undeclared tax under Articles 191 and 192. The difference between a EUR 30 surcharge and a EUR 1,500 fine on the same EUR 1,000 of late tax is entirely about who acts first.

What is the recargo de extemporaneidad?

The recargo de extemporaneidad is a surcharge that applies when a taxpayer files a self-assessment (autoliquidacion) or declaration after the deadline, without having received any prior request from the tax authority. Article 27 of the LGT defines it as a prestacion accesoria, an accessory charge, that replaces the sancion (penalty) and the interest de demora that would otherwise apply for the period before filing.

The surcharge follows a sliding scale set out in Article 27.2, as amended by Ley 11/2021 with effect from 11 July 2021. The rate is 1 per cent for filing within the first month after the deadline, plus 1 per cent for each additional complete month of delay. Once 12 months have passed, the recargo is capped at 15 per cent. At that point, interest de demora also accrues for the period from the day after the 12-month mark until the filing date. The AEAT publishes the full table on its recargos aplicables guidance page, showing 1 per cent in month one rising to 12 per cent in month 12, then 15 per cent plus interest beyond that.

A 25 per cent reduction on the recargo is available under Article 27.5 if the taxpayer pays the remaining 75 per cent of the surcharge within the notification period under Article 62.2 and pays the full tax debt at the time of filing or within that same period. This reduction rewards prompt payment after the surcharge is liquidated.

How does the sancion differ from the recargo?

The sancion is a punitive penalty imposed by AEAT when the tax authority discovers a failure to file or an incorrect filing through its own checks, not when the taxpayer comes forward voluntarily. The LGT separates the penalty regime into several articles depending on the nature and gravity of the infringement.

Article 191 governs the most common case for non-resident property owners: dejar de ingresar, failing to pay the tax debt that should have resulted from a correct self-assessment. The penalty is a proportional fine (multa pecuniaria proporcional) calibrated by severity. A leve infringement, where the unpaid amount is EUR 3,000 or less or there is no ocultacion (concealment), carries a 50 per cent fine. A grave infringement, where the amount exceeds EUR 3,000 with ocultacion, carries 50 to 100 per cent. A muy grave infringement, involving fraudulent means, carries 100 to 150 per cent. The key point: Article 191.1 explicitly states that the recargo de extemporaneidad under Article 27 replaces these sanctions, but only if the taxpayer regularises voluntarily before AEAT acts.

Article 192 covers failure to file declarations required for the tax authority to calculate the assessment (liquidacion) in non-self-assessment taxes. The same severity ladder applies: 50 per cent for leve, 50 to 100 per cent for grave, 100 to 150 per cent for muy grave with fraudulent means.

Article 198 is a narrower provision for late filing where no perjuicio economico (economic harm) occurs, meaning no tax was owed or the filing was purely informational. In that case the penalty is a fixed EUR 200 fine, or EUR 100 if filed voluntarily without a prior request. This does not apply to the typical non-resident property tax scenario where tax is owed.

What interest rate applies to late Spanish tax payments?

The interest de demora for 2026 is 4.0625 per cent annual, confirmed by the Agencia Tributaria on its official guidance pages. This rate is set by the Ley de Presupuestos Generales del Estado and remains in force until a new budget law changes it. The AEAT notes that the 2026 budget was still prorrogated from 2023 at the time of its latest update, so the 4.0625 per cent rate carried forward from 2025.

Interest accrues in two scenarios. First, under Article 27.2, if a voluntary late filing occurs more than 12 months after the deadline, interest de demora runs from the day after the 12-month mark until the filing date. Second, under Article 26, interest accrues on any tax debt not paid by the deadline, from the day after the deadline until the date of payment. For the recargo (under 12 months), no interest applies, which is one of its main benefits over the sancion path.

Recargo vs sancion: what does each scenario cost?

The table below compares the two paths on the same EUR 1,000 of undeclared Modelo 210 tax, filed three months late versus discovered by AEAT three months after the deadline.

Scenario	Who acts first	Charge	Amount on EUR 1,000 tax
Voluntary filing, 3 months late	Taxpayer	3% recargo	EUR 30
Voluntary filing, 12 months late	Taxpayer	12% recargo	EUR 120
Voluntary filing, 18 months late	Taxpayer	15% recargo + interest	EUR 150 + ~EUR 25 interest
AEAT discovery, leve (no ocultacion)	AEAT	50% sancion + interest	EUR 500 + ~EUR 123 interest
AEAT discovery, grave (with ocultacion)	AEAT	50-100% sancion + interest	EUR 500-1,000 + interest
AEAT discovery, muy grave (fraud)	AEAT	100-150% sancion + interest	EUR 1,000-1,500 + interest

The voluntary path is always cheaper. Even at 18 months late, the EUR 150 recargo plus roughly EUR 25 in interest (4.0625 per cent on EUR 1,000 for six months past the 12-month mark) is a fraction of the EUR 500 minimum sancion. The sancion path also adds interest de demora from the original deadline, not from the 12-month mark, so the interest cost is higher too.

Which Spanish property taxes does the recargo apply to?

The recargo de extemporaneidad applies to every Spanish tax that requires a self-assessment or declaration filed within a statutory deadline. For non-resident property owners, the most common are:

Modelo 210 (IRNR, non-resident income tax): Filed quarterly for rental income, annually for imputed income on empty property. A non-resident who misses the quarterly filing deadline for rental income and files voluntarily two months late pays a 2 per cent recargo on the tax due. The AEAT’s GZ71 procedure page confirms the recargo applies to all autoliquidaciones and declaraciones filed outside their deadline without a prior request.

IBI (Impuesto sobre Bienes Inmuebles): The local property tax. While IBI is typically collected by the town hall rather than AEAT, late payment triggers a recargo de apremio of 5 to 20 per cent under the via de apremio, a different surcharge for the enforcement period. This is covered in detail in our tax enforcement guide.

Modelo 720 (foreign asset declaration): The annual declaration of assets held abroad by Spanish tax residents. Late filing carries a fixed EUR 1,500 minimum fine per data block under the specific penalty regime for Modelo 720, which is harsher than the general recargo. This is one case where the Article 27 recargo does not soften the blow.

Modelo 211 (buyer retention on non-resident property sales): The 3 per cent retention on the purchase price that the buyer must withhold and pay to AEAT within one month of the sale. A buyer who fails to file Modelo 211 on time and is discovered by AEAT faces the sancion regime, not just the recargo, because the retention is a payment on account that the seller depends on for their capital gains reconciliation.

How does the voluntary late filing process work in practice?

The process for a voluntary late filing is straightforward but requires the taxpayer to act before any AEAT contact. The Agencia Tributaria defines a requerimiento previo as any administrative action carried out with formal knowledge of the taxpayer that is aimed at recognising, regularising, checking, inspecting or liquidating a tax debt. Once such an action is initiated, the recargo path closes.

To file voluntarily, the taxpayer submits the late return through the AEAT electronic platform (Sede Electronica), selecting the correct period and including only the data for that period. Article 27.4 requires the late self-assessment to expressly identify the tax period and contain only that period’s data. The system calculates the recargo automatically based on the months of delay. If the tax due is paid at the time of filing, no interest de demora applies for filings within 12 months. Beyond 12 months, interest accrues as described above.

The 25 per cent reduction under Article 27.5 applies when AEAT liquidates the recargo and the taxpayer pays 75 per cent of it within the Article 62.2 notification period and pays the full tax debt. This is the prompt-payment discount on the surcharge itself.

What triggers the sancion path instead?

The sancion path opens when AEAT discovers the failure before the taxpayer regularises it. For non-resident property owners, the most common triggers are:

AEAT’s automated cross-checking systems flag mismatches between declared rental income and bank transaction records, or between property sales registered in the Land Registry and Modelo 211 filings. Our non-resident tax audit guide covers the inspection process in detail. The 2026 Annual Tax Control Plan names non-resident property owners as a priority target, focusing on undeclared rental income and unreported capital gains.

The DAC7 framework (Ley 13/2023) requires digital rental platforms like Airbnb and Booking.com to report landlord income to AEAT via Modelo 238 by 31 January each year. This gives the tax authority a direct data feed that makes undeclared short-term rental income far harder to hide. A landlord discovered through a platform report faces the sancion regime, not the recargo.

Once AEAT issues a requerimiento, the taxpayer is in the sancion path regardless of how quickly they subsequently file. The penalty is calibrated under Articles 191 or 192 depending on whether the failure was to pay or to file, with the severity determined by the amount and whether ocultacion or fraudulent means were involved.

How does prescription interact with late filing?

Spain’s tax system has a four-year prescription period under Article 66 of the LGT: the right of the tax authority to assess a debt prescribes four years from the day after the filing deadline. However, prescription is not automatic. The taxpayer must invoke it, and any action by AEAT that acknowledges or pursues the debt interrupts the prescription clock, restarting the four-year period.

This means a non-resident who has not filed Modelo 210 for several years should consider both the recargo and the prescription implications. Our tax prescription guide explains the four-year rule and how to invoke it. Filing voluntarily under Article 27, even years late, can be a better strategy than waiting, because the recargo is capped at 15 per cent plus interest, whereas waiting for discovery opens the sancion path with penalties up to 150 per cent.

How can non-resident owners avoid late filing penalties?

The most effective defence is a reliable filing calendar. Non-resident property owners face multiple deadlines throughout the year: quarterly Modelo 210 for rental income (January, April, July, October), annual Modelo 210 for imputed income (by 31 December of the following year), and Modelo 720 by 31 January for those who are tax residents. Our non-resident income tax guide lists the filing obligations by property type.

A fiscal representative (representante fiscal) is mandatory for non-EU non-residents under Article 10 of the RDLeg 5/2004 (the consolidated IRNR law) and ensures filings are submitted on time. The AEAT electronic notification system under Article 14 of Ley 39/2015 means that once a fiscal representative is appointed, AEAT communications are deemed delivered even if the representative does not forward them, so choosing a competent representative matters.

If you have already missed a deadline, file before AEAT contacts you. The recargo de extemporaneidad under Article 27 is designed to reward voluntary compliance: it replaces the sancion and limits the cost to a percentage of the tax due. The alternative, a sancion of 50 to 150 per cent plus full interest from the original deadline, is the price of being caught.
