How much does a late Modelo 210 return cost?

The scale for voluntary late returns

Spain distinguishes between a taxpayer who corrects things spontaneously and one who waits to be caught. For a Modelo 210 filed after the deadline but without any prior request from the Agencia Tributaria, the recargo is:

• up to 12 months late: 1%, plus 1% for each full month that has passed since the deadline;
• more than 12 months late: 15%, plus late-payment interest counted from the end of that twelfth month.

After you file, the tax office sends a notice with the surcharge to pay. If you settle it within the period stated, the surcharge is cut by 25%.

Worked examples

Take a tax of €380, the amount for a €100,000 cadastral value at 2% and 19%.

Delay	Rate	Surcharge	After 25% reduction
2 full months	3%	€11.40	€8.55
6 full months	7%	€26.60	€19.95
11 full months	12%	€45.60	€34.20
Over 12 months	15% + interest	€57.00 + interest	€42.75 + interest

For a UK resident on the same property, the tax would be €480 and every surcharge a quarter higher.

What changes if the tax office writes first

Once you receive a requerimiento or a proposed assessment, the gentle scale no longer applies. The tax office can then assess the tax with interest and open a penalty procedure, which is generally more expensive than the voluntary surcharges. That is why acting before any letter is always the better choice. See I received a letter from the AEAT.

Keeping the cost down

• File all missing years together rather than one per month.
• Pay the surcharge notice promptly to keep the 25% reduction.
• Check the coefficient: some owners overpay at 2% when their town allows 1.1%.

The late-filing calculator gives your figure year by year, and the guide to late years explains the procedure.
