Your first 30 days as an autónomo

Last checked
For: Everyone
By Abdalsalaam Halawa

In your first 30 days you file the census form (declaración censal) with the where you live, register with Social Security on the same start date, and set up before the first invoice. This free checklist is that order. It is general information, not legal or tax advice, and this site is not a gestoría.

Open the checklist to read the steps in order. You can print it or save it as a PDF. The guide does not ask for an email address.

What the checklist covers

It is ordered. Each line links to the longer page in this guide and, where it matters, to the official service.

  • Before you register: your right to work, the , a bank account, a digital ID ( from , or an certificate, plus for Social Security), your Social Security number, your activity codes, and the grants to read before any registration.
  • Registration week: the census form at your Hacienda Foral, the Social Security registration () with the same start date, and the flat fee (tarifa plana) if you qualify.
  • Your first month: TicketBAI before the first invoice, what an invoice has to say, your records, and where to read the first tax deadlines.
  • By territory: the form, the free invoicing app and the tax calendar in Álava, Bizkaia and Gipuzkoa.

The list uses a figure from this guide only when that figure has a checked source. It does not invent a fee, a fine or a deadline.

What it does not do

  • It does not tell you which residence or work permit you qualify for. Start with Find your path.
  • It does not replace the pages of this guide. Each line links to the page that explains the step.
  • It is not a gestoría, and nobody here files the forms for you.

Official sources

The checklist links to the official page for each step. The same facts are written up, with their own check dates, on these pages:
