US-Spain tax treaty and Spanish property
Quick answer
The IRS lists a US-Spain income tax convention of 1990, a 2013 protocol and technical explanations. Treaties divide taxing rights and provide relief. They do not remove filing duties, and the US keeps the right to tax its citizens under a saving clause common in US treaties, so ask an adviser.
Applies toAmerican owners of Spanish property who want to know how the treaty works for them.
On this page: 10 sections
§ 1What exists
The IRS Spain treaty page lists the income tax convention with Spain, dated 1990, a protocol of 2013 that amends the convention, a technical explanation of the 1990 treaty and a technical explanation of the protocol. The page does not state when they entered into force, and we have not stated any date. This page belongs to the chapter in what changes for American buyers.
§ 2What a treaty does
A treaty divides the right to tax between the two states and requires relief from double taxation. For income from real property, treaties commonly allow the state where the property is to tax. For example, the Netherlands-Spain convention that we read lets income and gains from immovable property be taxed where the property is. We have not read the articles of the US-Spain text, so we do not state its detail. Read the convention, the protocol and the technical explanation for the articles on income from real property, on capital gains and on relief.
§ 3Residence
Treaties contain rules to decide residence when both states claim a person. US citizens are a special case, since the US taxes its citizens on worldwide income. US treaties generally preserve that right, with relief given through credits. The IRS pages we read do not set this out for Spain, so ask your adviser how it works in your case.
§ 4What a treaty does not do
It does not remove filing duties in either country. A non-resident owner of a Spanish home files Spanish returns, as the costs section explains, and an American files US returns, as US tax for Americans abroad explained explains. It does not set the Spanish rate, which comes from Spanish law, as taxes for American buyers explained describes.
§ 5Using it
Gather the facts: your residence, your income from the property, the Spanish tax paid, your US filing status. Ask your adviser to apply the articles and show you the result. Keep the proof of Spanish tax paid, since claims for relief need it.
§ 6Where to read
The IRS page links to the full documents. The Spanish tax agency lists Spain’s treaties. Treaty texts can be long, so ask for the relevant articles and the technical explanation, which is written to help readers.
§ 7The saving clause
US treaties usually contain a saving clause, which keeps the US right to tax its own citizens as if the treaty did not exist, with specific exceptions. We have not read the exceptions in the Spain text. This is why an American usually gets relief through credits rather than an exemption, and why the technical explanation is worth reading.
§ 8Questions for your adviser
Ask which articles cover rental income, a sale and any pension. Ask how credits for Spanish tax are claimed and which forms record them. Ask what happens if the Spanish tax is paid after the US return is due.
§ 9Related reporting
Foreign accounts bring reporting duties that are separate from the treaty. See how FBAR and Form 8938 works.

FAQRelated questions
Which treaty documents exist?
The IRS page lists the 1990 convention, a 2013 protocol that amends it and technical explanations of each. Read the convention and the protocol together. The IRS page does not state entry-into-force dates, so check them in the texts.
Does the treaty stop double tax on my rent?
Treaties provide relief from double taxation, typically by allowing credits. The exact effect on Spanish rent depends on the articles and on US and Spanish rules. A tax adviser can apply them to your numbers.
Where do I read it?
The IRS publishes the convention, the protocol and the technical explanations on its Spain treaty page. The Spanish tax agency also publishes Spain’s treaties. Ask for the articles on immovable property, residence and relief.
