How to Get a Tax Residency Certificate as an Expat in 2026

When you move abroad, one of the most important financial documents you will need is a Tax Residency Certificate (TRC). This document proves which country you are a tax resident of, and it’s critical for avoiding double taxation.

What is a Tax Residency Certificate?

A Tax Residency Certificate is an official document issued by the tax authority of the country where you are legally considered a tax resident. It confirms:

• ✅ You paid or owe taxes in that country
• ✅ You are entitled to benefits under that country’s double tax treaties
• ✅ Your previous country of residence should not tax the same income again

When do you need it?

• When closing bank accounts or investments in your home country
• When claiming tax treaty benefits on dividends, royalties, or pensions
• When your employer in a third country needs to know where to withhold tax
• When selling property in your home country as a non-resident

How to get a TRC: country by country

🇪🇸 Spain

1. Register with the Spanish Tax Agency (Agencia Tributaria)
2. File at least one Spanish tax return (IRPF or IRNR)
3. Apply online via the Sede Electrónica portal

Usually issued within 3–10 business days. Requires: NIE number, proof of Spanish residency, address in Spain.

🇵🇹 Portugal

1. Register with the Portuguese Tax Authority (AT)
2. File a Portuguese tax return (IRS)
3. Apply through the Portal das Finanças

Usually issued within 5–15 business days. Requires: NIF number, proof of Portuguese residency.

🇦🇪 UAE

1. Register for a UAE Tax Domicile Certificate through the Ministry of Finance
2. You must have lived in the UAE for at least 180 days
3. Apply online at mof.gov.ae

Cost: AED 2,000; usually issued within 5 business days.

🇩🇪 Germany

1. Register your German address (Anmeldung)
2. Get your tax number (Steuer-ID) from the Finanzamt
3. File a German tax return (Einkommensteuererklärung)
4. Apply for a residency confirmation from your local Finanzamt

Common mistakes to avoid

• ❌ Assuming residency begins the day you arrive — most countries require 183+ days/year
• ❌ Forgetting to deregister from your home country — you may still be taxed there
• ❌ Confusing immigration residency with tax residency — they are different
• ❌ Not filing in your new country quickly — late filing delays TRC issuance

Double taxation treaties

Most countries have bilateral tax treaties preventing the same income from being taxed twice. Germany has treaties with 90+ countries, Portugal with 79, Spain with 100+, and the UAE with 130+ countries — one of the world’s largest networks.
