Missed the Modelo 210 Deadline? Here's What to Do Now

Missed the Modelo 210 Deadline? The Short Answer

If you missed the Modelo 210 deadline — whether you forgot, didn't know, or simply didn't get around to it — the most important thing is to file voluntarily as soon as possible. Anyone who files late but does so on their own initiative can significantly limit the surcharges and, in most cases, avoid formal penalties entirely.

What Happens When the Modelo 210 Deadline Has Passed?

At Fiscaro, we regularly see owners who only discover their tax obligation years after the fact — often during a tax review or when preparing to sell their property. You're not alone, and the situation is manageable.

The key distinction:

Situation	What to expect
You file voluntarily	Graduated late surcharges (recargos), no penalty
The AEAT finds you first	Formal penalties + interest + possible additional demands
Multiple years outstanding	Each year is treated and calculated separately

The decisive factor: anyone who files voluntarily falls under the rules for voluntary late declaration (Art. 27 LGT — Ley General Tributaria). In this case, no formal penalty (sanción) applies — only the late surcharge and, if applicable, interest. Waiting for the AEAT (Agencia Tributaria, the Spanish Tax Agency) to act first is always the more expensive option.

Rule number one: act on your own initiative as quickly as possible.

Late Surcharges: How Much Will It Cost?

The late surcharge (recargo por presentación extemporánea) is governed by Art. 27 LGT in the version in force since the reform introduced by Ley 11/2021. The old tiered system (5/10/15/20 %) was replaced by a linear system that is generally more favourable for taxpayers:

1 % for the first month, plus 1 % for each additional full month of delay — up to 12 months
From 12 months onwards: a surcharge of 15 % — plus possible default interest

This means: filing 3 months late costs a 3 % surcharge. Filing 6 months late costs 6 %. The surcharges grow with every additional month — another reason not to wait.

Tip: 25 % discount for prompt payment Under Art. 27.5 LGT, the surcharge is reduced by 25 % if the principal tax and the remaining surcharge are paid on time after receiving the AEAT's demand notice. This reduction is not automatic — it requires timely payment. It's worth it, especially when multiple years are outstanding.

The surcharges are calculated on the principal tax — not on the property value or purchase price. For a typical self-use tax of around €150–300, the absolute surcharge remains manageable as long as you act promptly.

And: with a voluntary declaration under Art. 27 LGT, no formal penalty (sanción) applies. This is the decisive advantage over a procedure initiated by the AEAT.

What Will the Late Filing Actually Cost Me?

A practical example for a typical self-use case in Mallorca:

Example: Holiday apartment in Calvià, 1 owner (EU resident), self-use

Valor catastral (cadastral value, from the IBI (Impuesto sobre Bienes Inmuebles, Spanish annual property tax) notice): €80,000
Año de revisión (year of last cadastral revision): 2017 → factor 1.1 %
Tax base: €80,000 × 1.1 % = €880
Tax rate: 19 % (EU resident)
Principal tax: €167.20

Delay	Surcharge (1 % per month)	Total payment
1 month	1 % = €1.67	€168.87
3 months	3 % = €5.02	€172.22
6 months	6 % = €10.03	€177.23
12 months	12 % = €20.06	€187.26
Over 12 months	15 % = €25.08 + possible interest	from €192.28

The surcharges are manageable — as long as you act now rather than letting more years pass. Most owners significantly overestimate the cost of a late filing: in many self-use cases, the combined tax and surcharge comes to under €250.

Multiple Years Outstanding — What Then?

At Fiscaro, we frequently see owners who, at first contact, have not just one but two to five years outstanding. This happens most often when a property was not actively managed after purchase, or when the notary did not provide complete tax advice at the time of sale.

In this case:

Each outstanding year is declared separately and calculated separately
The surcharge for each year is based on the respective delay (1 % per month, 15 % from 12 months)
The principal tax can vary from year to year due to changes in the cadastral value

Example with 3 outstanding years (self-use, 1 owner):

Principal tax per year: approx. €167
Surcharges graduated by delay
Fiscaro price: €34.95 for all three years in one single process

Even with several outstanding years, the total in standard cases is significantly lower than most owners fear.

What Happens If the AEAT Acts First?

The AEAT has its own procedure for regularising outstanding IRNR declarations. If the tax authority identifies the omission before you act:

Formal penalties (sanciones) under the relevant LGT provisions — the amount depends on the individual case, the stage of proceedings, and any applicable reductions
Default interest on the outstanding tax
Administrative burden from the formal procedure

This is significantly more expensive than a voluntary late filing. The conclusion: don't wait.

How to File Retroactively

Option 1: File yourself For each outstanding year you will need:

NIE (Número de Identidad de Extranjero, Spanish foreigner ID number)
Digital certificate or Cl@ve access
The correct cadastral value from your IBI notice
The correct Modelo 210 form with the right tax year

The process is not straightforward, and errors in the calculation or the form can make the situation worse rather than better.

Option 2: Gestoría or tax adviser A Gestoría (Spanish administrative services firm) or asesor fiscal handles the late filing for you. Typical cost: €200–400 per declaration — multiplied accordingly for multiple outstanding years, based on our market observations in Mallorca.

Option 3: Fiscaro Fiscaro guides you through all outstanding years in one guided online process — correctly, promptly, and at a fixed price. No Spanish required, no bureaucratic hassle.

Fiscaro prices (self-use, current fixed price):

1 owner: €34.95 per year

Frequently Asked Questions

How far back can the AEAT claim unpaid taxes? Limitation periods depend on the individual case and can vary depending on the circumstances. Spanish tax law provides a general limitation period within which the AEAT can raise additional demands. If in doubt, seek professional advice — general statements on limitation periods are not reliable without knowledge of the specific case.

Do I need to submit a separate form for each outstanding year? Yes. Each tax year is declared separately — each declaration has its own due date and its own surcharge.

What happens if I have outstanding years and then sell the property? When selling, the buyer withholds 3 % of the purchase price and remits it to the AEAT via Modelo 211. Outstanding Modelo 210 declarations from prior years are separate — they must be resolved independently. Outstanding tax liabilities can trigger tax reviews or enquiries in connection with the sale. It is advisable to resolve the situation before completing the transaction.

Can Fiscaro also file for UK or Swiss owners? Yes. For owners outside the EU and EEA — including the United Kingdom and Switzerland — a tax rate of currently 24 % applies instead of 19 %. Fiscaro accounts for the different tax rates depending on country of residence.

What if I no longer have my IBI notices? The cadastral value can in many cases be retrieved via the Spanish cadastral authority (Dirección General del Catastro) or using existing tax documents. The specific accessibility depends on the applicable access rights. Fiscaro will help you identify the correct basis for the calculation.

The Bottom Line: Acting Now Is Always Cheaper Than Waiting

The Modelo 210 deadline has passed — that can't be changed. What you can influence is when you act. Every additional month increases the surcharge, and every additional year increases the risk that the AEAT initiates proceedings itself — at significantly higher cost.

The simplest step right now: calculate your outstanding tax and surcharge — it takes two minutes.
