Platforms will be forced to report every penny

Thousands of Brits and Spaniards who own holiday homes in Spain – whether they are living in the sun or just savvy investors renting out villas for extra cash – now face the full force of Spain’s taxman. And the golden age of cash-in-hand lettings? It’s over.

If you have a bolt-hole on the Costa del Sol or a flat in Tenerife raking in weekend bookings, you’re now firmly on Hacienda’s radar. Airbnb and Booking.com are legally required to spill the beans on you – and we’re talking names, dates, addresses and income. Everything.

And don’t assume you’ll stay off the UK taxman’s radar either. While HMRC isn’t directly involved in this crackdown, Spain and the UK do share financial data, even post-Brexit. So if you’re not declaring your overseas earnings back home, you could be in for a nasty surprise at both ends.

As tax cooperation tightens across borders, the message to UK and Spanish landlords is simple: What happens in Marbella doesn’t stay in Marbella – not if the taxman gets wind of it.

So if you’ve been renting out your Spanish place to friends, family, or strangers, and forgetting to mention it in your returns, now’s the time to get squeaky clean. Because Hacienda’s gone digital, and they’ve got your number.

Airbnb and Booking.com will be forced to report every penny to Spain’s tax authority

Thanks to a newly enforced reporting scheme, dubbed Modelo 179, rental platforms are now legally required to snitch. That’s right – Airbnb, Booking, and their pals must now send Hacienda detailed breakdowns of every booking, every euro earned, and exactly who earned it.

That means your full name, tax ID, exact address of the property, how much you charged, and when it was rented – all sent straight to the taxman’s desk.

The goal is to stop under-the-table lets and level the tax playing field between traditional long-term landlords and the booming holiday rental market.

No more cash in hand

The days of carefree cash-in-hand stays are over. Now, every short-term landlord must report income as part of their annual Declaración de la Renta – and not just the income, but all related expenses too.

Think utilities, cleaning, management fees and council taxes – yes, those can be deducted. But miss a detail? Slip up on your figures? That’s when things start to sting.

Hacienda has already issued warnings. Forgetting to declare can lead to hefty fines, painful surcharges, and full-blown inspections that dig deep into your finances. For anyone hoping to stay under the radar – that window has firmly shut.

Big boom, big spotlight

What’s sparked this sudden clampdown? One word: money.

The short-term let industry has ballooned in recent years, particularly in tourist magnets like Madrid, Malaga, Barcelona, San Sebastian, and Valencia. What started as a side hustle has become a multi-million euro machine – and now Hacienda wants its slice of the pie.

A spokesperson made the message crystal clear:

‘The holiday rental sector is no longer a fiscal black hole. Everyone must pay their fair share – just like in any other economic activity.’

Platforms turned informants

If you thought Airbnb was just your friendly neighbourhood booking tool, think again. It’s now part of the tax compliance squad.

Rental platforms must send monthly data reports to Hacienda – every listing, every stay, every payment. It’s a digital dragnet that makes it nearly impossible to slip through unnoticed.

So what now?

Landlords who want to stay on the right side of the law must:

• Check what the platform reported on their behalf
• Declare all rental income in full
• Accurately list deductible expenses
• Match their returns to the data Hacienda already has

Hacienda’s message is loud and clear: if you’re making money from short-term lets, it’s time to declare it or prepare for a knock at the door.

Because while your guests might be on holiday, Hacienda never is.
