Administrative services for expatriates in Barcelona

Tax Advice for Expatriates in Barcelona

A foothold in Spain for SaaS and tech companies

Tax advice for foreign nationals in Barcelona

If you are a foreign national living, working or investing in Spain, specialist tax advice will help you comply with the regulations and manage your taxes more efficiently.

At GR International Advisors, we handle the accounting for expats and international professionals in Barcelona, including tax returns, international tax planning and wealth management.

Problems we solve

Most expats arrive in Spain with accounting organised in another country that doesn’t directly fit Spanish regulations.

This causes:

  • Lack of coordination between countries: Your accountant back home and the Spanish Tax Agency don’t speak the same language. We act as a bridge so everything adds up.
  • Obligations you weren’t aware of: Modelo 720 (assets abroad) and Modelo 721 (cryptocurrencies). Many expats discover these only once a penalty has already been issued.
  • Incomprehensible reporting: You receive documents in Spanish format that tell you nothing useful. We give you information you can actually read and use.
  • Lack of annual follow-up: A change of contract, a new account, a property in another country: everything has implications. We let you know before they affect you.

Well-adapted accounting management avoids problems and gives you real visibility over your situation.

Accounting for an expat is not the same as accounting for any other client

Accountancy for expats in Barcelona

International accounting involves a level of complexity that most accountancy firms in Barcelona do not handle effectively. That is precisely what we specialise in.

We analyse your full situation before we start – your income, assets, country of origin and reporting obligations – and tell you exactly what needs to be done and when. No surprises, no last-minute rushes.

You live in Barcelona. We’ll make sure the tax authorities aren’t a problem.

Frequently asked questions


Do I have to declare my accounts abroad if I live in Spain?
If you are a tax resident in Spain and the combined balance of your accounts abroad exceeds €50,000, you must file Modelo 720. Failure to comply can result in significant penalties. We help you check whether you’re required to file and handle the process correctly.
What happens if I have cryptocurrencies on an exchange outside Spain?
Since 2024, Modelo 721 exists, specifically for cryptocurrencies held abroad. This is a recent obligation that many expats are still unaware of. We can take care of the entire process for you.
Do you work in English?
Yes. We offer support in Spanish, English and Catalan. A large proportion of our clients are international, and we adapt to whichever language suits you best.
Do you only work in Barcelona?
Although our office is in Barcelona, we work with clients across the whole of Spain and offer 100% online advice. We work with individuals and businesses in Madrid, Valencia, Málaga and other cities.
