If you want to freelance or start your own business in Spain but aren’t ready to commit full-time, you can become part-time self-employed.
This guide explains what that means legally, how to register, your obligations with Social Security and the Tax Agency, and what to expect in costs and benefits.
By the end, you’ll know whether this setup works for you - and how to do it right.
Is there such a thing as “part-time self-employed” in Spain?
Not officially. There’s no legal category for “autónomo a media jornada,” but you can work part-time hours while registered full-time.
Can I pay less Social Security if I work part-time?
Only through pluriactividad - if you’re employed and self-employed at the same time, you can get discounts.
Do I still have to file taxes?
Yes. You’ll have the same obligations as any other freelancer: invoices, quarterly VAT and income tax filings, and bookkeeping.
There’s no official legal status for part-time autónomos.
Spanish law (Ley 20/2007 del Estatuto del Trabajo Autónomo) mentions the idea but never applied it. In practice, you register like any other freelancer under the Régimen Especial de Trabajadores Autónomos (RETA) and pay the same monthly Social Security fee - no matter how many hours you work.
The closest equivalent is pluriactividad.
That’s when you work as an employee and also have your own freelance activity. It’s the only way to legally combine both and pay lower Social Security contributions.
Key takeaway: You can work part-time hours, but your contributions and tax obligations are the same as for full-time freelancers - unless you qualify for pluriactividad.
Even if you only plan to work a few hours a week, you must register correctly:
If you’re not an EU citizen, you’ll also need a self-employed visa.
There’s no “hour threshold” for being part-time - you must follow the same rules as full-time autónomos.
Pluriactividad means you’re both an employee and a freelancer.
Main benefit: Lower Social Security contributions for your self-employed activity during the first 18–36 months.

Drawbacks:
Tip: Tools like renn can automatically check if you qualify for pluriactividad, apply the right reductions, and make sure you don’t miss available tax credits or deductions.
Self-employed contributions are based on your income bracket, not on hours worked.
Whether you work 5 or 40 hours per week, you pay based on your declared net income under the new 2023–2025 “real income” system.
If you earn little, the minimum quota (about €230/month in 2025) still applies - unless you get a pluriactividad discount.
Example:
If you’re employed and self-employed for the first time, you might pay only 25–50% of the normal quota during the first 18 months.
Tip: Estimate your real income before registering. If it doesn’t cover the fixed costs, it may be better to wait until your freelance work grows.
Don’t forget recurring costs: bookkeeping, VAT and IRPF filings, and accountant or software fees.
Being part-time doesn’t change your tax obligations.
You must still file:
You can deduct usual business expenses such as:
If you’re both employee and self-employed, your total income is added together for IRPF, which may move you into a higher tax bracket. Keep separate accounting records for each income source.
Tip: If unsure, consult a gestor (tax advisor) specialized in autónomos to confirm your eligibility and optimize your setup.
You can be “part-time self-employed” in Spain, but the law treats you like any other freelancer.
You’ll have the same registration, tax, and quota duties - unless you qualify for pluriactividad, which offers real savings.
Plan your income, know your fixed costs, and use this phase to safely test and grow your business. With the right setup and tools, it can be a smooth bridge from employment to full-time self-employment.
