Tax & business advisory

We offer comprehensive, personalised support if you are self-employed (autónomo), run a small or medium-sized business, need help with your personal taxes, or live outside Spain and have income or assets here. We look after the tax, employment and administrative side so that you stay compliant, make the most of your resources and can work with peace of mind.

And because we are a law firm, we don't stop at filing returns: if the Spanish tax office (Hacienda) sends you an information request, proposes an assessment or imposes a penalty, we prepare the submissions and appeals, through the administrative route and, if needed, in court.

Tax advice for the self-employed, SMEs, individuals and non-residents

• Self-employed. Registration, changes and deregistration with the tax office and Social Security, quarterly and annual returns, income and expense records, payroll if you have employees, and electronic notifications.
• SMEs and companies. Company formation, changes and dissolution, tax returns, accounting obligations, payroll and social security contributions, and representation before public bodies.
• Individuals. Income tax (IRPF) and wealth tax returns, capital gains and losses, rental income, corrections to returns already filed, and the tax side of inheritance and gifts.
• Non-residents. Non-resident income tax (IRNR), Spanish tax ID (NIF), tax residence certificates, double taxation, and the tax treatment of buying, selling or letting property in Spain.
• Defence before the authorities. Information requests, tax reviews, inspections, penalties and seizures.

Situations where we often help

• You are about to register as self-employed and don't know which tax regime applies to you or which expenses you will be able to deduct.
• Your turnover keeps growing and you are wondering whether to stay self-employed or set up a company.
• You have received an information request or a proposed assessment from the tax office and don't know how to reply.
• You need to adapt your invoicing to Verifactu. As a general rule, if you invoice with software, it will have to meet the new requirements from 1 January 2027 if you pay corporate income tax, and from 1 July 2027 in all other cases, such as the self-employed.
• You live abroad and own a home in Spain: even if you don't let it, as a general rule you must declare imputed income on it every year.

How we handle your case

1. Free initial orientation. Ten minutes by phone to understand your situation and tell you whether it's worth pursuing.
2. Consultation. We go through your figures and documents and give you a concrete strategy.
3. Proposal with a transparent quote. Before we start, you know what we are going to do and what it costs. No obligation to continue.
4. We handle it. We file, reply and follow up. You always deal with the same person.

Deadlines worth knowing

• Quarterly returns. As a general rule, VAT (form 303) and, where it applies to you, income tax instalments (form 130) are filed from 1 to 20 April, July and October, and from 1 to 30 January for the fourth quarter.
• Income tax return. The filing campaign generally runs from April to 30 June.
• Electronic notifications. If you are required to receive them (companies always are, and the self-employed are in their dealings with Social Security), a notification you don't open within ten calendar days is treated as rejected and the procedure moves on.
• Appeals. As a general rule, you have one month from the day after notification to lodge an appeal for reconsideration (recurso de reposición) or a claim before the tax tribunals (reclamación económico-administrativa).
• Limitation period. As a general rule, the tax office has four years to review a tax (counted from the end of the filing period), and you have the same period to claim back any overpayment.

What to bring to your first consultation

• Your NIF or NIE (foreigner identity number) and, if you have one, your digital certificate.
• Your latest returns (income tax, quarterly returns and annual summaries).
• The notification you received and the date you opened it or it was delivered.
• Related invoices, record books, deeds or contracts.
• If you are not resident in Spain: your tax residence certificate and details of your assets or income here.

Fees

A full consultation by phone or video call (45 minutes) costs from €50 + VAT (€100 + VAT on Saturdays), and an in-person meeting at the office on Calle Núñez de Balboa 120 (60 minutes, by appointment only) from €65 + VAT. If you then instruct us on the matter, the consultation fee is deducted.

If you would rather we handled your taxes all year round, there are monthly plans for the self-employed and companies from €60/month + VAT. Not sure which one fits? Try Which plan suits me? or book a tax consultation. Our tax blog has updates and practical guides.

Frequently asked questions

Can you help me if I don't live in Madrid?

Yes. Most procedures are handled online, so we work with clients all over Spain and abroad, in English and Spanish, and we reply within 24 working hours.

Is it better to be self-employed or to set up a company?

It depends on your income, your expenses, the risks of your business and your plans. We look at your figures and, if switching doesn't pay off, we'll tell you.

I've received a letter from the tax office. What should I do?

Don't ignore it, and check the deadline, which is usually short. Send it to us as soon as possible: we'll look at what they are asking for and prepare the reply or the submissions.

Is it the same as using a gestoría?

We cover the same ground as an accountancy and tax agency (gestoría) — returns, bookkeeping, payroll — with one difference: if a dispute with the authorities arises, we stay with you for the appeals and, if needed, in court.
