Frequently asked questions
How is it different from the full self-employed registration?
This procedure only registers you with the Tax Office. It doesn't include Social Security. If you also need to register as self-employed, choose "Self-employed registration: Tax Office and Social Security".
When does only the Tax Office registration make sense?
For example, if you already pay Social Security contributions some other way, or if you're going to register with Social Security yourself.
Do I have to do anything?
Answer the questions and give us permission to deal with the Tax Office for you, only the first time. We explain how, step by step.
Do I have to create an account?
No. When you finish we email you a link so you can see how your procedure is going whenever you want.
What do you do with my data and documents?
We keep them encrypted and in Europe while the procedure lasts. When it's finished you decide whether we delete them straight away; if you don't tell us anything, we delete them after 90 days.
Are the forms in English?
Our website is in English, but everything filed with the Tax Office and Social Security has to be in Spanish. We fill it in for you in Spanish and explain what each item means.
