Post-Brexit Compliance in Spain: What UK Expats Still Need to Do in 2025

Since the UK officially left the EU, British citizens living in Spain have had to adjust to new rules around residency, taxation, and travel. Even if you registered before the original Brexit deadline, there are still things you need to stay on top of in 2025 to ensure you remain fully compliant with Spanish law.

1. Do you have the correct residency card?

If you're still holding the older green A4 certificate or green card, it's recommended — though not mandatory — to switch to the biometric TIE card. The TIE clearly shows your protected status under the Withdrawal Agreement and makes life easier at borders and in admin processes.

Read our step-by-step guide to the residency process.

2. Keep your padrón up to date

Every British expat should be registered on the padrón municipal (local census) and keep that registration current. Most town halls require it to be renewed every two years if you're a foreign resident.

What is the padrón and why it matters.

3. Are you registered for healthcare?

Depending on your status (employed, retired, or self-sufficient), you should be either registered in the public system or have private health insurance that meets visa requirements. This is especially important if you're applying for TIE renewal or travelling.

Explore compliant private health insurance plans if you're self-employed, retired, or applying under the non-lucrative or nomad visa routes.

4. Declaring income and paying taxes

If you're a tax resident in Spain (living here more than 183 days per year), you're required to declare your worldwide income and may need to submit a Modelo 720 asset declaration if you hold more than €50,000 abroad. Staying tax-compliant is key to maintaining your residency status.

5. Check travel rules

If you haven't switched to a TIE, remember your green residency certificate does not guarantee smooth entry at borders. The TIE, being biometric and in Spanish format, is the preferred proof when dealing with authorities or airlines.

6. Is your documentation current?

Ensure that your passport is valid, your address is up to date with Spanish authorities, and that you've notified the ayuntamiento if you've moved. Regularly reviewing your admin can help avoid problems down the line.

Conclusion

Even in 2025, being “Brexit-compliant” isn’t just about having stayed in Spain — it's about continuing to meet the requirements that keep your residency status and rights fully intact. Review your documents, renew what’s needed, and stay informed on any changes. That way, you’ll enjoy your life in Spain with full peace of mind.
