The service at a glance
WHAT IS INCLUDED AND WHAT IS NOT PROMISED
Tax registration decides your whole fiscal year: the activity code, whether you are on the right VAT regime and which returns will be demanded of you. Correcting it later always costs more than getting it right.
What it includes: choosing the activity code and the tax regime; completing and filing the form; explaining which returns apply to you from then on. What it does not include: it does not include social security registration as self-employed, which is a separate procedure quoted apart.
DOCUMENTS YOU WILL NEED
ID document and, for a company, deed of incorporation and tax number.
A real description of the activity you will carry on.
Tax address and business address.
INDICATIVE TIMING
We answer your enquiry within 1 working day and send the written quote within 2 working days.
Once your documents are complete, we prepare the file between 1 and 3 working days.
Tax census registration is filed before the activity starts; it is only delayed if the Tax Agency (AEAT) asks for a clarification.
See the pricing page for how we charge this kind of matter.

Frequently asked questions
WHAT ABOUT FORM 037?
It no longer exists: since February 2025 everything is done with form 036. If someone asks you for form 037, what applies is form 036.
CAN I REGISTER WITH A PAST DATE?
A past start date can be declared, but it may carry a surcharge. We tell you the risk first.
DOES THIS REGISTER ME AS SELF-EMPLOYED?
Not entirely: social security is still missing. They are two registrations and we do both if you want.
