In short
A non-resident who keeps a home in Spain without letting it pays income tax on an imputed income of 2% of its cadastral value (1.1% where the values were revised recently): on a cadastral value of €100,000, that is €2,000 of income and €480 of tax a year at 24% for a UK, Canadian or US resident. An EU or EEA resident pays 19%: €380. With the 1.1% rate, the UK, Canadian or US owner pays €264.
What changes next
For 2026, Real Decreto-ley 29/2026 extends the 1.1% rate to municipalities whose values were revised from 1 January 2012 (additional provision 55 of Ley 35/2006), subject to validation by the Cortes. From 1 January 2027, Real Decreto-ley 29/2026 (art. 6) replaces the 2%/1.1% rule with a scale of 1.1% to 3% on the sum of cadastral values, subject to validation by the Cortes; its application to non-residents is not settled by the texts read.
