Prepayment register

The prepayment register is one of the Tax Administration’s registers. A company or self-employed person can submit an application for registration. The purpose of having a prepayment registration is to prove that your company deals with its taxes on its own. 

Attention begins.

Newly started companies – note the following:

Even if you are on the prepayment register, you have to ask the Tax Administration for a decision on prepayments. You must do this yourself, and you must pay the installments during the current year. 

The prepayments are your business’s forthcoming income taxes. The idea is to pay installments as your business earns profits during the year.

Attention ends

What is the meaning of the prepayment register?

Your company can show it carries full responsibility for paying its own taxes. In this case, your customer – another company, a household, or other – can pay your invoice as it is, so the customer will have no need to withhold tax on the money they pay you. If no registration is in force, it means that any customer of yours would need to withhold some tax for the Tax Administration upon every payment. 

  • Your customer can pay the invoice as it is, and this will be enough.
  • After you finish the work for your customer, you will deal with your company’s taxes independently.

If your customer is a household or an estate of a deceased person, they can claim a credit for household expenses if the work justifies it.

If no prepayment registration is in force, your customer must withhold tax on the payment (which you had invoiced) before sending it to your company for the delivered work or service.

The customer would need to calculate the withholding by first subtracting the value-added tax on the invoice, and then applying the withholding rate. Sizes of withholding rates: 

  • Corporate entities and partnerships (including limited liability companies, associations, partnerships): 13%
  • Self-employed persons who operate trade or business, other individuals: the percentage rate is stated on their tax cards for nonwage pay. If the person fails to present the card, the withholding is 60%.

The seller’s prepayment registration has no significance if:

  • The customer pays wages to the seller of a service: the withholding is always based on the individual seller’s tax card.
  • The customer buys goods or rental services paying the invoice: no tax withholdings are required.

If you are a customer and you get an invoice and both work and goods are being invoiced and the seller company is not on the register, you must withhold tax on the amount consisting of work.

How to get the registration for your company

If you are a company or a person operating a trade, business, agriculture, or another activity with the objective to gain or produce income, you can submit an application. Your operation does not have to be started yet – it is enough if it is likely to start.

However, there is no mandatory rule that would require anyone or any company to have the registration. However, when you have just started up, it might be difficult to make any sales or receive orders if your company is not on the prepayment register.

The Tax Administration will enter the company into the register either from the date when the application was received or from a later date that you had indicated in the application documents. You will receive the registration decision in MyTax. Registration information will also appear on the Business Information System website immediately after registration.

The Tax Administration must decline a registration sometimes – for example, if the activity is clearly a hobby, or if the applicant has a history of negligence relating to taxes or to the duty to keep books.

Select the instructions according to your company form

You can register for prepayment in MyTax at the same time as you start your operation. Alternatively, you can also register later when you have been issued a Business ID.

How to exit the prepayment register

Companies or self-employed individuals can ask for removal from the prepayment register in MyTax. Among the most common reasons for de-registration on a company’s initiative is that its planned operation of business never started or was discontinued. De-registration on the Tax Administration’s initiative is possible, as well.

After an application for de-registration is processed, the Tax Administration will issue a decision on removal from the register. Information concerning ceased registration will also appear on the Business Information System website.

Alternatively, you can request removal from the register via the Business Information System.

In what circumstances can the Tax Administration remove a company from the register?

Removing a company or self-employed person from the prepayment register on the Tax Administration’s initiative might happen in the following situations:

Companies can be removed if:

  • the company’s business activities have ended
  • no activity ever started
  • the activities are a nonbusiness pursuit, like a hobby, not a business activity.

You will always receive information on a removal being pending, and you can provide a written explanation. If you can show you have a business operation ongoing, no removal is made. You can register again if there is a delay and the operation of your business will begin later.

Removal from the register as a consequence of negligence, including:

  • non-payment of taxes
  • obligations to declare income and report information are neglected
  • obligations to keep records, books, ledgers are neglected
  • other tax-related obligations are neglected

You will be notified on a pending removal beforehand, and you can remedy any negligence.

Further reasons for a company to be removed are related to the person leading the company:

  • the person has a history of previous neglect with regard to the tax liability of companies previously owned or managed
  • the person is subject to a business prohibition.

Setting up a new company to avoid de-registration on the Tax Administration’s initiative is not feasible.

You can apply for prepayment registration again

If you had been removed from the prepayment register, you can apply again.

If negligence had been the ground, you can register again only when:

  • you remedied the negligence that led to the removal, and
  • you haven't had any new occurrences of negligence.

The Tax Administration will give you the registration either from the date when the application was received, or from a later date that you had indicated in the application.

How to check whether a company has a prepayment registration 

If you are the customer making a payment for work or services, check the seller’s registration before sending the payment. If the seller is on the prepayment register, you can pay the seller’s invoice. There is no need for tax withholding. If the seller is not on the register, you must withhold tax.

The existence of any party’s prepayment registration is public information. You can check registrations by:

  • Business search on the BIS/YTJ website: Type in the name or Business ID of the company to run a check. The service is free of charge.
    • If the company is registered, the start date of registration is shown on the BIS website.
    • If you are about to pay an invoice and you make the check that the company is registered, you can trust this information even if the company were to be removed from the register later.
  • Call the Tax Administration’s telephone service 029 497 006 (standard call rates)
  • The Ilmoitin.fi e-Service: You can make checks on prepayment registrations and VAT registrations of multiple companies at once. The service is free of charge.

To check registrations, companies can also use the services of private, paid service providers.

How often should I check another company’s prepayment registration?

It is advisable to check the registration before you send a payment. If your operation of a trade or business involves making payments to one single company on a regular basis, we recommend that you make the check at least four times a year (like March, June, September and December).
