UK-Spain double taxation treaty and Spanish property
Quick answer
The UK government says the UK has a double taxation agreement with Spain so that you do not pay tax on the same income in both countries. It allocates taxing rights and gives relief. It does not remove filing duties. Residents of Spain must declare assets held outside Spain, with penalties for errors.
Applies toBritish owners of Spanish property who want to understand double taxation relief.

§ 1What the treaty is
The UK government’s guide to living in Spain says that the UK has a double taxation agreement with Spain so that you do not pay tax on the same income in both countries. A tax treaty is an agreement between two states that divides the right to tax and sets rules for relief. For owners of Spanish property the treaty matters in outline, and it sits within what changes for British buyers. It does not replace advice on your own case.
§ 2What treaties usually do
Treaties generally say which country may tax which kind of income, and give the other country a duty to give relief, either by crediting tax paid abroad or by exempting the income. For income from real property, treaties commonly allow the country where the property is to tax it. For example, the Netherlands-Spain convention, which we read, lets income and gains from immovable property be taxed where the property is. We have not set out the UK-Spain text here, and you should read it or ask an adviser for the article that applies to you.
§ 3What treaties do not do
They do not remove filing duties. A non-resident owner of a Spanish home still files the Spanish returns the costs section describes. A UK resident may still report the income or gain in the UK and claim relief for the Spanish tax. They also do not set the rate of Spanish tax, which comes from Spanish law.
§ 4Residence and the treaty
If you are resident in both countries under their rules, the treaty usually contains tie-breaker tests to decide. The tax residency chapter in the residency section explains the Spanish tests and the idea of tie-breakers. A British owner who moves to Spain should look at both the Spanish tests and the treaty.
§ 5Declaring assets
The UK government states that residents in Spain must declare all assets they hold outside Spain and may need to file an annual return, with penalties for not filing or for incorrect or incomplete information. The information return is explained in the residency section. This applies when you are resident in Spain, not to a UK resident who owns a Spanish home.
§ 6Where to find the text
The UK government’s page links to the agreement. The Spanish tax agency also publishes Spain’s treaties. A tax adviser who knows both systems can read the relevant articles for you.
§ 7Practical steps
Keep a record of the Spanish tax you pay, with receipts. Ask your UK adviser how to claim relief. And do not assume that the treaty removes the need to file. The wider changes since Brexit are in how buying after Brexit works.

FAQRelated questions
Does the treaty mean I pay no tax in Spain?
No. It prevents the same income being taxed twice in full, by dividing taxing rights and giving credit or exemption. Income from property is generally taxed where the property is, so Spanish tax usually applies to income from a Spanish home.
Do I still file returns?
Yes. A treaty gives relief but does not remove the duty to file. Non-resident owners file Spanish returns for the home, and UK residents may need to report the income in the UK and claim relief.
What if I move to Spain?
Becoming a Spanish resident brings a duty to declare overseas assets, with fines for omissions or errors. See the residency section for that return and for the tests that decide residence.
