Going freelance in Spain? First, the honest bit: becoming autónomo in Spain — the legal status for working for yourself — is more involved, and frankly more expensive, than it is in a lot of countries. Whether you’re a remote consultant, a plumber or running a little shop, it’s worth understanding the costs and the steps before you send your first invoice, not after. Here’s how it works in 2026.
This sits under our Taxes in Spain hub and our Living in Madrid guide; for the wider move, see moving to Spain.
What does “autónomo” even mean?
An autónomo is a self-employed worker or sole trader. There’s no separate company — you and the business are one and the same for tax and liability — which makes it the simplest set-up for freelancers and most small operators, as opposed to forming a proper company (sociedad limitada).
Who has to register?
If you’re carrying out an economic activity on your own account — regularly, and to make money — you generally have to register as autónomo. And yes, that holds even if all your clients are abroad. Remote workers on the Digital Nomad Visa who freelance often register too, depending on how they’re set up.
The two registrations behind becoming autónomo in Spain
Signing up happens in two places, and you need both:
- Hacienda (the tax office) — file Modelo 036/037 to register your activity for tax and VAT, declaring what you do and where.
- Social security (RETA) — join the special regime for the self-employed to pay your monthly contribution and earn your healthcare and pension rights.
You’ll need your NIE, a Spanish bank account, and a digital certificate (certificado digital) to file online.
What it costs: the monthly cuota
Here’s the number that makes people wince. Every autónomo pays a monthly social-security contribution — the cuota. Spain now runs an income-based system, so your cuota is tiered to your real net earnings: earn less, pay less; earn more, pay more. The saving grace for newcomers is the reduced flat rate (the tarifa plana), usually available for your first year or so, which takes a lot of the sting out of the start-up cost. On top of the cuota, you’ll set money aside for income tax and, usually, VAT.
Your ongoing obligations
Once you’re registered, life takes on a certain rhythm of paperwork:
- Quarterly VAT (IVA) returns — charging and handing over IVA (standard rate 21%), unless your activity is exempt.
- Quarterly income-tax (IRPF) payments on account.
- An annual income-tax return (the renta) that squares up the year.
- Keeping proper invoices and records.
Most autónomos hand all this to a gestor — it’s cheap and it saves you from expensive slip-ups.
Invoicing clients abroad
This one catches out a lot of remote workers, so read it twice. If you invoice business clients elsewhere in the EU, you generally shouldn’t charge Spanish IVA — but only once you’ve registered on the ROI (the register of intra-community operators) and you’re validated on the EU’s VIES system, quoting both parties’ VAT numbers on the invoice. Bill clients outside the EU and the rules shift again. It’s genuinely fiddly, and getting it wrong means either over-charging your clients or quietly owing IVA you never collected — which is precisely why most autónomos with foreign clients let a gestor handle it.
Don’t forget your deductions
It’s not all outgoings. Legitimate business expenses — a portion of your home office and utilities, professional software, your accountant’s fee, work travel, the gestor — can generally be set against your income, trimming the tax you actually pay. The rule of thumb: keep every invoice, keep it in the business’s name, and log it as you go. Do that and the quarterly maths gets a great deal friendlier.
Is it worth it?
If you’re planning to work for yourself in Spain for the long haul, registering isn’t really optional. But the tarifa plana, access to healthcare and pension, and simply being able to invoice legally make it perfectly manageable. My one bit of advice: build the cuota and tax into your day rates from the very start, so there are no nasty surprises at quarter-end.

Getting help
A good gestor can register you, sort your digital certificate and run your quarterly filings for a modest monthly fee — genuinely one of the better hundred-or-so euros you’ll spend.
