Modelo 720 in Spain: What UK Residents Must Declare (It Wasn't Abolished)
Modelo 720 wasn't abolished — only the disproportionate fines were struck down in 2022. Here's what UK residents in Spain actually have to declare about assets back home, and by when.
This is not tax advice. The thresholds and figures below are verified against official Spanish sources at the time of publication, but your personal situation changes everything. Speak to a UK accountant and a Spanish gestor before making any decision based on this article.
If you've searched for this, you've probably seen someone claim Modelo 720 was abolished. It wasn't. What changed in 2022 was the punishment for getting it wrong — not the obligation itself. If you become a Spanish tax resident, you still have to declare what you own abroad.
What Modelo 720 actually is
It's an information return, not a tax bill. Once you become a Spanish tax resident, you must declare assets held outside Spain — the UK savings account, the ISA, the buy-to-let flat in Manchester — if any single category crosses 50,000€. There's nothing to pay simply for filing it; it exists so the Agencia Tributaria knows what you hold abroad. This sits entirely apart from any mortgage or property costs you already manage in Spain.
The 50,000€ threshold — three separate boxes, never combined
This is where people trip up. The threshold applies separately to three categories, not to your total foreign wealth:
- Bank accounts held outside Spain.
- Securities, shares, insurance policies and investment funds held outside Spain.
- Real estate located outside Spain.
Cross 50,000€ in any one category and you declare that category. Having 40,000€ in a UK bank account and a 45,000€ ISA doesn't trigger anything, because neither category alone reaches the threshold — they're never added together.

So why does everyone say it was abolished?
Because something real did happen — just not what people think. In January 2022, the EU Court of Justice ruled that Spain's original penalty regime for Modelo 720 was disproportionate: fixed fines of 5,000€ per error, and a 150% surcharge treating undeclared assets as an "unjustified capital gain" with no time limit on when Spain could come after you. Spain scrapped that regime the same year. What replaced it is the general tax penalty framework — real, but nowhere near as punishing. The form itself, and the obligation to file it, never went anywhere.
What about assets you already owned before moving to Spain
This is the part that actually matters for most British buyers who eventually settle here: your UK savings, pension pots and investments existed long before you became a Spanish tax resident. A 2022 Spanish Supreme Court ruling set the statute of limitations for reclassifying undeclared foreign assets as an "unjustified gain" at the standard 4 years — it's no longer indefinite. Assets you can document as acquired before your Spanish residency began generally sit outside that recharacterisation risk, provided you can show the acquisition date. Keep the paperwork.
Before you file anything:
- Work out your exact Spanish tax residency date with a UK accountant — the obligation starts from there, not from when you bought a property.
- Have a Spanish gestor check each category against the 50,000€ threshold individually.
- Keep dated records of UK accounts and investments opened before you moved — proof of timing is what protects you.
- Don't wait until March: gathering UK statements and valuations takes longer than people expect.
What Legado does isn't tax advice — it's making sure the purchase itself goes smoothly: an independent lawyer who works for you, not the developer, and the NIE and paperwork checklist non-residents need before they even get to residency questions. This is the second article in a short series on Spanish tax for British buyers — the wealth tax piece covers what changes if you own above a much higher threshold, and the third piece covers what renting out or selling the property costs on both sides of the Channel.
Frequently asked questions
Was Modelo 720 abolished?
No. Only the old, disproportionate penalty regime was struck down by the EU Court of Justice in 2022. The obligation to declare foreign assets remains fully in force.
What has to be declared?
Foreign bank accounts, securities and insurance, and real estate — each assessed separately against the 50,000€ threshold, never combined into a single total.
What is the deadline?
1 January to 31 March each year, covering what you held as of 31 December of the previous year.
What happens if I do not declare?
Fixed penalties under the general tax regime since 2022: around 20€ per omitted item, with a minimum of 300€ and a maximum of 20,000€ per category — far lower than the old regime, but still real.
Does this apply to assets I owned before moving to Spain?
Yes, they still have to be declared once you become a Spanish tax resident. But a 2022 Supreme Court ruling set a standard 4-year statute of limitations on reclassifying undeclared assets as an unjustified gain, and assets you can prove you already owned before your residency began generally fall outside that risk.
