### 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](https://iberfacil.es/en/pricing) for how we charge this kind of matter.

### How it works

1. **WE IDENTIFY THE EXACT PROCEDURE** Depending on the activity you will carry out, we tell you which heading fits and which VAT and income tax regime you fall under.
2. **DOCUMENT LIST AND QUOTE** We ask for your ID, the business address and the start date. Price agreed before anything is filled in.
3. **FILING AND RECEIPT** We complete and file the census form through the tax agency portal and hand you the receipt.
4. **TRACKING AND CORRECTIONS** We leave you in writing which quarterly and annual returns you will have to file from that date, and tell you if the tax office asks to correct the registration.

#### What to have at hand

- 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

### 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.
