Self-employed: you do the work, we do the paperwork
We look after many self-employed people in Sant Cugat and the Vallès. Being self-employed means doing a bit of everything. We take quarterly returns, the books and dealings with the tax office and Social Security off your hands, and tell you what you can deduct so you don’t overpay.
Error-free registration
If you’re just starting out, we register you with the tax office and Social Security and explain the flat-rate scheme and income-based contributions. We do this every week for self-employed people who are just starting.
Quarterly returns up to date
We prepare and file your VAT and personal income tax (IRPF) returns, and send you a reminder in good time. We also review your self-employed contributions when your income changes.
Deductible expenses
We help you understand what you can deduct and how to keep your invoices so the tax office doesn’t reject them.
Advice for the self-employed, professionals and small businesses
We work with self-employed people of all kinds. Consultants, designers, shop owners, healthcare professionals or technicians: if you work for yourself, we tailor the service to what you really need.

We get to work

Frequently asked questions from the self-employed
If you have any other questions about being self-employed, write to us and we’ll answer them.
Which taxes do the self-employed have to file each quarter?
Most self-employed people file quarterly VAT returns and make instalment payments of personal income tax (IRPF), unless they are under the flat-rate (módulos) scheme or have tax withheld on almost all their invoices. On top of that, there are annual information returns and the income tax return. We keep track of the calendar and let you know what is due before each deadline, so there are no surprises.
How do income-based self-employed contributions work?
Your Social Security contribution is calculated on your expected net earnings and adjusted once Hacienda has the final figures. That is why it is important to adjust it during the year if your income changes. We review the contributions of the self-employed clients we look after and suggest changing bracket when it makes sense, so you avoid paying a large difference at the end.
Can I register as self-employed with you?
Yes. We register you with the tax office and Social Security, tell you whether you qualify for the flat-rate contribution (tarifa plana) or any other reduction, and explain which invoices and expenses you need to keep. In a single meeting you’ll know how your day-to-day will work and who will help you when you have questions.
What expenses can I deduct as a self-employed person?
Those linked to your business activity and backed by an invoice: materials, utilities for your premises, insurance, professional fees, training or part of your household costs if you work from home, within limits. Every case has its nuances, which is why we review the expenses of our self-employed clients every quarter to make the most of what is deductible without taking risks.
Do you also handle the income tax return for self-employed people?
Yes. Because we handle your quarterly returns throughout the year, preparing the income tax return for self-employed clients is much simpler: we already have your income, expenses and advance payments, and we just need to add the personal and family details.
