Frequently asked questions
Do I need a digital certificate?
No. As a Punto de Atención al Emprendedor (Entrepreneur Support Point) we register you with the Tax Office and Social Security at the same time, in a single procedure. You just check the draft and sign it.
Can I get the flat rate?
If you haven't been self-employed in the last 2 years (3 if you've had it before), you pay €80 a month during the first year. We ask you when doing the registration and apply for it for you.
How much will my contribution be?
It depends on how much you expect to earn each month. With that figure we choose the lowest contribution you're entitled to. It's adjusted every year with your income tax return.
What about the mutual insurer (mutua)?
We recommend Mutualia, the Basque mutual insurer, but you can choose another one. It's who looks after you if you're off sick.
I'm a foreign resident. Can I use this?
Yes, as long as you live in Bizkaia and have a DNI or NIE. If you're not from the EU, EEA or Switzerland, we'll also ask for a photo of your work permit or residence card that allows you to work.
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.
