International & non-resident tax advisors in Spain
Tax advice for expats, foreign residents and non-residents with interests in Spain and abroad.
Living, working or investing across two countries turns tax into a minefield: double taxation, reporting obligations you didn’t know you had, and penalties that arrive years later. We help you whether you’re moving to Spain, leaving, or living abroad with income or assets here. One team handles your Spanish income tax or your non-resident tax (IRNR), the treaties that apply to you and your information returns — so you pay exactly what you owe and Hacienda never surprises you.
Why cross-border tax can't be handled piece by piece
Your tax residency decides which country taxes your worldwide income. The treaty between those two countries decides who taxes each type of income. And your reporting obligations — Form 720, Form 721 — depend on both. They’re parts of the same problem: if a different advisor handles each one, or you handle it yourself, the connections get missed and the mistake shows up two years later, with interest and surcharges. Here the same team sees all of it, in the same file.
Tax residency analysis
We determine which country you're a tax resident of —the 183-day rule, your centre of economic interests, where your family lives— and, when two countries claim you at once, we resolve it under the treaty tie-breaker rules. Includes the tax residency certificate and mid-year residency changes.
Double taxation treaties (DTT)
We identify the treaty that applies to you, decide whether you're entitled to the exemption or the credit method, and use the reduced withholding rates at source, so the same income isn't taxed twice.
Non-resident income tax (IRNR)
If you don't live in Spain but own property or earn income here: deemed rental income on an own-use home, taxation of rental income, and capital gains plus municipal plusvalía on a sale.
Spanish income tax with foreign income
Your Spanish resident tax return when you have salary, a pension, dividends or property abroad, applying the exemption or double-taxation relief that applies.
Form 720 and Form 721
Reporting of overseas bank accounts, securities and property above €50,000, and of crypto-assets held outside Spain. We check whether you're required to file and handle voluntary disclosure if you were previously undeclared.
International inheritance and gifts
Successions and gifts with assets or heirs in more than one country, coordinating the tax treatment in each jurisdiction.
Expats, foreign residents
and non-residents:
different starting points, one team
If you’re moving to Spain, we set the date from which you’re taxed here on your worldwide income and check whether the Beckham regime suits you. If you’re a foreigner buying property, we get you compliant with non-resident tax (IRNR) even if you don’t live in the country. If you’re leaving Spain, we handle the residency deregistration properly so Hacienda doesn’t keep treating you as resident. And if you live abroad with accounts, property or an inheritance in Spain, we sort out what’s declared here and what’s declared there.

What changes when you work with us
We don’t compete on being the cheapest — we compete on leaving no part of your cross-border tax position unchecked.
- A fixed advisor who knows your two-country case, not a rotating desk.
- 25+ years with residents, non-residents, expats and companies operating abroad.
- Preventive approach: we fix it before the tax inspection, not after.
- Support in English and Spanish.
Undeclared overseas assets or a tax notice about foreign income
If you have overseas accounts, property or crypto-assets you’ve never declared, or you’ve received a notice from Hacienda about foreign-source income, we file a voluntary disclosure before proceedings open, and represent you if they’re already under way. The aim is to cap the cost and close the risk, not just answer the letter.

How we run your international case, wherever you are
Most of our international tax clients aren’t in Spain when they contact us. We start with a video diagnostic call; electronic signature is legally valid before the Spanish Tax Agency and any other body; documents are managed through an always-on online channel; and if your case touches another jurisdiction, we coordinate with a partner firm there. The same advisor from start to finish, replying within 30 minutes.
Frequently asked questions
How do I know if I'm a tax resident in Spain?
You’re a tax resident if any one of three conditions applies: you spend more than 183 days in Spain during the calendar year, your main centre of economic activities or interests is here, or your non-separated spouse and minor children habitually live in Spain. If another country also treats you as resident, the double taxation treaty decides under tie-breaker rules (permanent home, centre of vital interests, habitual abode, nationality).
What is a double taxation treaty and how does it stop me paying tax twice?
It’s a treaty between two countries that assigns each the right to tax each type of income and sets a mechanism (exemption or credit) so the same income isn’t fully taxed in both. Applying it means identifying the right treaty, proving your residency with a certificate, and calculating the relief you’re entitled to.
Do I have to file Form 720?
Yes, if on 31 December or at any point in the year you held more than €50,000 outside Spain in any of three categories: bank accounts; securities, insurance or annuities; or real estate. Crypto-assets held abroad above that threshold are reported on Form 721. In later years you only re-file if a category increases by more than €20,000 or if you close or sell something previously reported.
I'm a non-resident with a property in Spain — what tax do I pay?
If you don’t rent it out, you pay non-resident tax (IRNR) on deemed rental income (a percentage of the cadastral value) once a year, plus the municipal IBI. If you rent it out, you’re taxed on the income: residents of the EU, Iceland, Norway and Liechtenstein can deduct expenses; others can’t. And when you sell, you settle the capital gain and the municipal plusvalía, with a 3% withholding the buyer pays on account.
I've just moved to Spain, or I want to switch advisors mid-year — is that a problem?
No. We review your situation from the moment you arrive to fix the date from which you’re taxed here and check whether the impatriate regime suits you. And if you already had an advisor, we run an initial review of what’s been filed so the handover leaves no return uncovered.
Do you work with clients outside Spain?
Yes. We work with residents and non-residents across Spain and abroad, entirely remotely (video call, electronic signature and online document management), with the same deadlines and guarantees as an in-person consultation.
