Keeping track of Spanish tax deadlines is one of the biggest pain points for expats on the Costa del Sol. Miss the Modelo 720 deadline by a single day and you are looking at penalties that far exceed the cost of filing. Miss a quarterly autónomo submission and the surcharges start accumulating immediately.
This checklist puts every deadline you need on a single page, so you can plan ahead instead of scrambling in March.
What’s Inside:
- Modelo 720: what triggers it + what to gather before March 31, 2026
- IRPF “Renta”: the practical doc list to start collecting now (see our income tax guide for the full breakdown)
- Autónomo quarterly filing deadlines (Q1 to Q4) so you do not get hit with surcharges
- The 183-day residency trigger — and how to track days without overthinking it
- …and more deadlines + monthly maintenance so you do not miss the informativas that cause headaches.
For a detailed walkthrough of every deadline, see our full Spain Expat Tax Deadlines Calendar. If you are earning rental income or have capital gains to report, those have their own filing windows that this checklist also covers.
Not sure whether the Beckham Law changes your deadlines? It does not change when you file, but it changes what you owe. Understanding the difference between Beckham Law and normal taxation will help you prepare the right documents ahead of each deadline.
A good gestoría will track these deadlines for you, but you should still know them yourself. If your gestor misses a deadline, it is your problem, not theirs. Our guide to finding a good gestor on the Costa del Sol covers what to look for.
If you hold property, remember that IBI property tax has its own payment window that varies by municipality. Marbella, Málaga, and Fuengirola all have different schedules.

Frequently Asked Questions
What are the most important tax deadlines for expats in Spain?
The three deadlines that catch the most expats are Modelo 720 (foreign asset declaration, due March 31), the annual IRPF income tax return (Renta campaign, April 1 to June 30), and quarterly autónomo filings if you are self-employed (due by the 20th of the month following each quarter). Missing any of these triggers automatic surcharges and, in the case of Modelo 720, potentially significant penalties.
What happens if I miss a tax deadline in Spain?
Late filing triggers surcharges that increase with time. Filing within 3 months of the deadline incurs a 5% surcharge. Between 3 and 6 months, it rises to 10%. Between 6 and 12 months, 15%. After 12 months, the surcharge is 20% plus interest. For Modelo 720 specifically, penalties start at €5,000 per unreported data item, though the EU court ruling in 2022 reduced the most extreme penalties. Filing late is always better than not filing at all.
Can my gestor file everything for me?
Yes. A gestor or asesor fiscal can handle all your Spanish tax filings, including Modelo 720, IRPF, quarterly autónomo returns, and wealth tax declarations. You will need to provide them with the supporting documents (bank statements, income records, foreign asset valuations), but they handle the actual submissions. Budget €200-500 per year for a gestor who handles standard expat tax filings on the Costa del Sol.
Do I still need to file if I arrived in Spain mid-year?
If you became a Spanish tax resident during the year (by crossing the 183-day threshold or meeting other residency criteria), you may need to file for the full tax year. Spain considers you resident for the entire year in which you become resident, not just from the date of arrival. This means your worldwide income for the full year may be reportable. Get advice from a tax professional in your first year to avoid surprises.
Are there different deadlines if I use the Beckham Law?
The filing deadlines are the same whether you are on the Beckham Law regime or standard taxation. What changes is the form you file (Modelo 151 instead of the standard IRPF) and what income is reportable. Your gestor needs to know which regime you are on to file the correct forms by the correct deadlines.
