Overseas assets: what Spanish tax residents need to know

Overview

Beyond declaring foreign income, Spanish tax residents with assets abroad — property, investment accounts, business interests — have two separate things to think about: the annual Modelo 720 disclosure, and how those assets factor into Wealth Tax. This guide connects the two; each has its own detailed rules.

Requirements

• Applies to Spanish tax residents who own assets located outside Spain

Step-by-step process

• Check whether your overseas assets cross the Modelo 720 reporting thresholds — see our detailed guide to Modelo 720 for the specific category-by-category rules
• Remember that as a tax resident, your overseas assets also count towards your worldwide net wealth for Wealth Tax purposes, not just your Spanish assets — see our detailed guide to Wealth Tax
• Keep valuations of foreign property, investment accounts and other assets up to date each year, since both obligations require a snapshot as of 31 December
• If you dispose of overseas assets at a gain, check whether Spanish Capital Gains Tax applies, since Spain taxes worldwide gains for residents just as it does worldwide income

Required documents

• Valuations or statements for all overseas property, accounts and investments as of 31 December

Common mistakes

• Treating Modelo 720 and Wealth Tax as the same obligation — they're separate filings with separate thresholds and purposes, and meeting one doesn't cover the other
• Not realising that overseas property or investments can also trigger Spanish Capital Gains Tax when sold, even though the asset was never physically in Spain

Practical tips

• Keep a single, organised annual record of all overseas assets and their values — it serves both your Modelo 720 filing and your Wealth Tax calculation, so there's no need to gather this information twice
• If your overseas assets are substantial or complex (business interests, multiple properties, trusts), professional advice covering both obligations together is worth the cost
