If you are a UK resident letting a Spanish property, are you taxed twice on the rent? In practice, no — but you do declare it in both countries. Spain taxes the rental income where the property is located, and the Spain–UK double taxation treaty then lets the UK give you credit for the Spanish tax you paid, so the same income is not taxed twice. What you feel is the higher of the two tax bills, not both added together.
Reviewed by María Luisa de Castro, abogada (ICA Cádiz nº 2745) — CostaLuz Lawyers has advised UK owners on their Spanish rental tax since 2006.
Brexit did not end this. The Spain–UK double taxation convention is a bilateral treaty, not an EU instrument, and it remains in force. What Brexit did change is the Spanish rate: a UK resident is now treated as a non-EU landlord, which affects both the rate and what can be deducted — the part most UK owners get wrong.
How the two systems fit together
- Spain taxes first. Income from a property located in Spain is taxed in Spain as non-resident income tax (IRNR), filed on Modelo 210. This is the country-of-location rule the treaty follows.
- The UK taxes your worldwide income. As a UK resident you also declare the Spanish rent on your UK Self Assessment — but you claim Foreign Tax Credit Relief for the Spanish tax already paid.
- The credit prevents double taxation. The UK reduces its bill by the Spanish tax, so you effectively pay the higher of the two rates once — not both.
- Post-Brexit, you are a non-EU landlord in Spain. That means the higher non-EEA IRNR rate and, unlike EU residents, you generally cannot deduct expenses against the Spanish rent — see how the Spanish bill is calculated.
The practical order is: pay the Spanish IRNR correctly first, keep the proof, then claim the credit in the UK. Getting the Spanish side wrong — missing the annual filing or over-claiming deductions you are no longer entitled to as a non-EU resident — is what triggers problems on both sides.

Frequently asked questions
Am I taxed twice on Spanish rental income as a UK resident?
Not on the same income. Spain taxes it first as the country where the property is; the Spain–UK treaty then lets the UK give credit for the Spanish tax, so you effectively pay the higher of the two rates once.
Did Brexit end the Spain–UK double taxation treaty?
No. It is a bilateral treaty, not an EU instrument, and remains in force. Brexit did change your Spanish rate, because a UK resident is now taxed as a non-EU landlord.
Where do I declare the rental income?
In both countries: on Spanish Modelo 210 first, then on your UK Self Assessment where you claim Foreign Tax Credit Relief for the Spanish tax paid.
