Free registration with your subscription
Become self-employed without paperwork, and without paying to register
Registering shouldn't be your first headache. We handle the whole process with the Spanish Tax Agency and social security so you can start invoicing legally as soon as possible — and it's free with your subscription.

What it means
What it means to register as self-employed
Becoming self-employed essentially means telling the authorities that you're going to carry out an economic activity on your own account. That means two registrations: one with the Spanish Tax Agency (form 036, which declares your activity and your IAE code) and one with social security (RETA registration, which sets your monthly contribution).
Getting it wrong — the wrong code, the wrong dates, a missed deadline — can cost you money and stress later on. That's why we do it for you, right first time.
The right IAE activity code
We pick the right activity code with you, so you're taxed correctly from day one and there are no surprises later.
Census and RETA registration
We file your form 036 with the Spanish Tax Agency and register you under the special scheme for self-employed workers (RETA).
Real guidance
We explain your obligations, your deadlines and the social security contribution you'll pay, including whether the flat rate applies to you. No jargon.
Nothing for you to worry about
We take care of everything
You don't need to know what an IAE code is, or fill in form 036. You tell us what you'll be doing and we do the rest: paperwork, deadlines and procedures, from start to finish.

No registration fee
Registration is free when you start with us
Many accountancy firms charge a separate fee just to register you. Not at autonomia360: it's included with your subscription, at no extra cost.
You just choose a plan when you start using the platform (from €15/month). For the registration itself, not a euro more.
Included with any subscription plan.

Frequently asked questions about registration
How much does registering cost?
The registration process is free when you register with autonomia360: no extra cost, it's included with your subscription. You only pay your monthly plan (from €15/month) once you start using the platform.
How long does registration take?
We normally have your registration processed within 24–48 business hours of you telling us about your activity. We'll let you know as soon as you're ready to invoice.
Do you help with the flat rate?
Yes. We'll tell you whether the flat rate for new freelancers applies to you and how much you'll pay, so there are no surprises with social security.
What do I need to get started?
Little more than your ID and a clear idea of what you'll be doing. We handle the rest: the code, the forms and the deadlines.
I'm already a freelancer — is this any use to me?
Yes. If you're already registered, we help you switch accountancy firm and handle any change to your census details. Free registration is for people starting out with us.
