The start-up notification and official registrations
If you are a self-employed individual or an agricultural operator, you can use MyTax to start up a new activity. However, to set up a limited liability company, general partnership or a limited partnership, you must always send a start-up notification to the Business Information System (the YTJ/BIS e-service).
How to establish a new business and obtain registrations
After you have submitted the start-up notification, we will have your company registered with our Register of taxpayers. When submitting the notification, you can additionally submit requests for other official registrations depending on your needs. The important registers include the VAT register, the prepayment register and the register of employers.
Select instructions according to your company form:
- If you start a business activity, you can use MyTax to ask for a Business ID to be issued to your new company and to request registration with the Tax Administration’s registers. Direction and guidance: How to request a Business ID and sign up for the Tax Administration’s registers in MyTax
- If you start a business activity and submit a registration application to the Trade Register, you will need to file a start-up notification in the YTJ/BIS e-service. Read more about when to contact the Trade Register (PRH)
- If you have a Business ID, you can submit requests for registrations with the Tax Administration’s registers either through the YTJ/BIS e-service or in MyTax. Direction and guidance: How to sign up for the Tax Administration’s registers in MyTax
- If you cannot use electronically provided services, you can send your start-up notification on paper – Form Y3 – and complete the appropriate fields on it to request registration with the Tax Administration’s registers as needed. You can download the “Y” forms in the YTJ/BIS e-service
To submit the start-up notification of a limited-liability company, a general or a limited partnership, use the YTJ/BIS e-service. Your new entity will be issued a Business ID, and you can also request registration for it with the Tax Administration’s registers as needed
Submit a start-up notification in the YTJ/BIS e-service
When your company has its Business ID, you can also request registrations with the registers afterwards. This is done in MyTax. Alternatively, you can submit a Notification on changes, to request various registrations for the company in the YTJ/BIS e-service.
How to sign up for the Tax Administration’s registers in MyTax
If you are an individual taxpayer and you start up as a farmer or forestry farmer, you can use MyTax to apply for a Business ID and request registration with the Tax Administration’s registers.
What kind of operations will make it mandatory for you to apply for VAT registration?
You can submit an application for registration with the Register of Associations in the e-service of this official register – or on Form Y1a on paper.
If you submit Form Y1a on paper, you can also submit, according to your needs, any requests for registrations with the registers maintained by the Tax Administration by completing and enclosing Form 6212 as well.
If the association is already on the Register of Associations and you plan to submit applications for registrations with the Tax Administration’s registers later, the form to complete is the Change notification 6214. Later, you can use the Change notification again to inform the Tax Administration of any subsequent changes.
The start-up notification form for a foundation is Form Y1.
The forms are available for downloading in the YTJ/BIS e-service
Tax partnerships include agricultural partnerships, forestry partnerships, real estate partnerships and VAT partnerships.
You can submit an application for registration of a tax partnership on Form Y2 on paper. You can also request registrations, according to your needs, with the registers maintained by the Tax Administration at the same time. It is possible for a tax partnership to have a VAT registration for primary production, for business activities, or for transfer of rights of use over real estate property.
If the partnership already has a Business ID, you can also request registrations with the registers afterwards. Alternatively, you can submit Form Y5 on paper, i.e. the Notification on changes form.
The forms are available for downloading in the YTJ/BIS e-service

When will I receive my Business ID?
If you submit the start-up notification electronically, either in MyTax or in the YTJ/BIS e-service, you will receive the Business ID immediately. If you submit the start-up notification on paper, the Business ID will be shown in 3 days on the YTJ/BIS company search.
When can I start operating the new business?
Provided that the sector of your company’s activity is not subject to a legal restriction like special permits, qualifications, etc., you can start as soon as you have submitted the start-up notification.
After you have submitted the notification and received your company’s Business ID, you can
- Have a bank account opened for the company
- Make arrangements for a bookkeeping system
- Buy the insurance policies your company might need
- Deal with other administrative issues
For detailed information on pension insurance for the self-employed (under the YEL laws), please contact your insurance company. Pension insurance policies designed for operators of agriculture (MYEL) are made with the farmers' pension insurance institution Mela.
When can I start billing?
After you have received the Business ID for your company, you can start sending out invoices immediately. If you request and obtain a VAT registration for your company, you can start writing out invoices with VAT added to the invoiced sum of money.
If you have submitted an application for prepayment registration, it is advisable to wait until you receive the decision from the Tax Administration, which will officially confirm your company’s registration. Until then, your customer – the company that pays you – must withhold tax on any amount of money they are paying.
It takes about 3 weeks to finalise a new company’s registrations with the Tax Administration’s registers. See more detailed processing times.
