Key rules

• Gestor: A gestor covers routine filings and paperwork.
• Asesor fiscal: Hire one when foreign income or assets make your case complex.
• Fees: Fees vary by case, so get a written fixed quote after the adviser has seen your documents.
• Insurance: Check the adviser's qualifications and professional indemnity insurance before hiring.

Hire an asesor fiscal only when your situation is complex

If your tax affairs are simple, a gestor is enough. Hire an asesor fiscal when the complexity justifies the cost. Foreign income and assets are the usual reason.

Gestor or asesor fiscal?

A gestor is a regulated professional who handles paperwork and filings: vehicle registration, company formation, payroll and routine tax returns. An asesor fiscal is a tax adviser. They give advice, plan your taxes, prepare returns and represent you before the AEAT, Spain's tax agency.

The two roles overlap, and many firms offer both. Lawyers and economists can also work as tax advisers. So look at what the person does, not only the title.

Signs you need an asesor fiscal

Consider one if any of these apply to you:

• Property, rental income, pensions or employment income abroad.
• Foreign bank or broker accounts that may need a Modelo 720 declaration.
• Crypto, or a foreign company or trust.
• A question about a tax treaty, or a sale of an asset abroad.
• Income in several countries, or a complex foreign tax credit calculation.
• An inheritance or gift from abroad.
• Arriving in or leaving Spain, including the Beckham regime.

If none of these apply, ask a gestor first. They can tell you if the case is more than routine.

What to expect to pay

Fees vary by case. The price depends on how many foreign accounts, properties, dividends and capital gains you have, and on whether you need a Modelo 720 or a foreign tax credit. A simple return is cheap. Returns with foreign income, rentals or crypto cost noticeably more.

Advisers who focus on expats usually charge more than local ones. Many quote a fixed fee once they have seen your documents. Ask for the quote in writing and ask what it covers.

Before you choose

• Check their qualifications.
• Ask whether they hold professional indemnity insurance.
• Ask whether they have handled cases like yours.

Frequently asked questions

Is a gestor enough, or do I need an asesor fiscal?

A gestor is enough for routine paperwork, but an asesor fiscal fits better when you need tax advice or planning. A gestor is a regulated professional who handles filings such as vehicle registration, payroll or company formation. The roles overlap and many firms offer both, so ask what the person will actually do for you.

Which foreign situations are worth paying an asesor fiscal for?

Foreign property, rental income, foreign pensions, crypto, a foreign company or trust, or a sale of an asset abroad are all common reasons to hire one. Other triggers are moving to or leaving Spain (including the Beckham regime, a special tax regime for new arrivals), income in several countries, and inheritances or gifts from abroad. A complex foreign tax credit calculation is also a good reason.

How much does an asesor fiscal cost for a return with foreign income?

The cost depends on how complex your return is, so there is no single price. A simple return is cheap, while foreign accounts, properties, rentals, crypto or a foreign tax credit cost noticeably more.

What should I check before choosing a tax adviser in Spain?

Check the adviser's qualifications and ask whether they hold professional indemnity insurance. A gestor should be registered with a Colegio de Gestores Administrativos. Lawyers and economists can also act as tax advisers, so ask about their experience with foreign income.
