Registering, deregistering or changing your details with the tax office

We file form 036 or 037 with the right activity codes and obligations, which is what determines everything you will have to declare afterwards.

Tax registration, deregistration and changes (forms 036/037)

What is included

  • Choosing the activity code and the tax regime
  • Completing and filing the form
  • Explaining which returns apply to you from then on

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.

Registration takes effect immediately on filing; it is only delayed if the tax office asks for a clarification.

See the pricing page for how we charge this kind of matter.

How it works

Estimated duration: 3 days.

  1. We identify the exact procedure

    Depending on the activity you will carry out, we tell you which heading fits, whether form 036 or 037 applies 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

Form 036 or 037?

Form 037 is the simplified version and does not cover every case. We look at yours and use the right one.

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.
