Denmark E-tax for Businesses Guide (TastSelv Erhverv)

Logging On to E-tax for Businesses

There are two ways to log on to TastSelv Erhverv depending on your business type and location.

Danish businesses — MitID Erhverv: If your business is registered in Denmark, you log on using MitID Erhverv (the business version of Denmark's national digital ID). Sole proprietors (enkeltmandsvirksomhed) can use their personal MitID. Companies (ApS, A/S) need MitID Erhverv associated with the company's CVR number. Log on at skat.dk/tastselverhverv and select "Log on with MitID". You will be redirected to the MitID authentication page where you approve the login via the MitID app or code reader.

Non-Danish businesses — E-tax password: If your business does not have a Danish CVR number (e.g., foreign businesses using the VAT One Stop Shop), you need an E-tax password (TastSelv-kode). Order one at skat.dk — the password is sent by letter to your non-Danish address. When you receive it, activate it using the instructions in the letter. You must then enable two-factor authentication before you can log on. Use your customer number as your login ID. For the process, see the E-tax portal section below.

Two-Factor Authentication

Two-factor authentication (2FA) is a mandatory security requirement for accessing E-tax for businesses. It requires two separate forms of identification:

Setting up 2FA (first-time users):

1. After ordering and activating your E-tax password, click "Log on".
2. When prompted, click "Send new activation code" — the code is sent to the email address you specified in your registration.
3. Click the link in the email and enter the code.
4. Scan the QR code displayed on screen using an authenticator app on your phone (any authenticator app works — Google Authenticator, Microsoft Authenticator, etc.).
5. Enter the code shown in the authenticator app on the screen.
6. Two-factor authentication is now enabled and you can log on.

You need to complete this process once. On subsequent logins, you enter your password and then the code from your authenticator app. Keep your authenticator app accessible — if you lose access, you will need to order a new E-tax password and repeat the setup. For detailed instructions, see SKAT's guide to logging on with two-factor authentication.

Authorising Employees and Accountants

You can give other people access to your business's E-tax for businesses through role-based authorisation. This is essential if you use an accountant or revisor, or if multiple employees need to handle different tax tasks.

Give employees access: Log on to TastSelv Erhverv, go to Profile information and contact details, then Rights and access to E-tax. Here you can grant specific employees access rights to various parts of the system — VAT filing, payroll reporting, tax account viewing, excise duties, etc. You can grant full access or limited access (read-only or restricted to specific functions). Each employee needs their own MitID Erhverv to use the access you grant. Review and update access rights regularly, especially when employees leave the business.

Authorise your accountant/consultant: Accountants and revisor firms need authorisation to report information on behalf of your business. The process is similar — log on to TastSelv Erhverv, go to Rights and access to E-tax, and grant the relevant permissions to your accountant's firm. The accountant then uses their own MitID Erhverv to log on and act on your behalf. You can revoke authorisation at any time. Note that your accountant must also be registered for the Accountant Scheme (Revisorordningen) to file certain types of returns on your behalf.

Accountant Scheme (Revisorordningen)

The Accountant Scheme (Revisorordningen) is a SKAT registration for businesses that report information on behalf of other businesses. If you are an accountant, revisor, or bookkeeping firm, your business must register for this scheme to file VAT returns, corporate tax returns, and other reports on behalf of clients.

How to register:

1. Log on to E-tax for businesses (TastSelv Erhverv).
2. Select Profile information and contact details.
3. Select Rights and access to E-tax.
4. Select Register for the Accountant Scheme.
5. Tick off "Tilmeld til Revisorordning" (Register for the Accountant Scheme).
6. Click "Tilmeld til Revisorordning" at the bottom right-hand corner.

Your business is now registered. You can then be authorised by your clients to report information on their behalf. Registration must be done by the business itself — clients cannot register your firm for the Accountant Scheme on your behalf.

Registering for Contact with SKAT

To send and receive secure messages with SKAT through TastSelv Erhverv, your business must register for Contact with the Danish Customs and Tax Administration.

How to register:

1. Log on to E-tax for businesses (TastSelv Erhverv).
2. Select "Profil" (Profile) in the menu.
3. Select "Profiloplysninger" (Profile data) in the left-hand menu.
4. Select "Tilmeldingsoplysninger" (Registration data).
5. Select "Kontakt med Skatteforvaltningen" (Contact with the Customs and Tax Administration).
6. State the email address you want SKAT to reply to.

After 30 minutes, you can write to SKAT by using "Skriv til os" (Write to us) and view replies under "Se svar fra os" (See our reply) under Contact. Make sure your browser allows pop-ups from E-tax for businesses — otherwise the messaging interface will not load.

Determine which employees have access: After registering for Contact, decide which employees should have access to see the communications. This is done through the same Rights and access settings described above.

E-tax Portal for Non-Danish Businesses (OSS/VAT)

If you are a non-Danish business using the VAT One Stop Shop (OSS) scheme, you access your Danish VAT account through a special E-tax portal. This portal handles OSS VAT reporting and payments for businesses not established in Denmark.

First-time access: Order an E-tax password at skat.dk using your customer number. The password is sent by letter to your non-Danish address. Activate it and set up two-factor authentication as described above. After setup, log on at the dedicated OSS portal link on skat.dk.

Payments in the portal: All amounts are calculated in DKK and must be paid in DKK. When SKAT receives a payment, it covers entries ready for payment in chronological order according to the FIFO principle (first in, first out). This means older debts are settled before newer ones. If you have multiple outstanding amounts, your payment is applied to the oldest due amount first.

Why no letters about outstanding VAT: SKAT does not send letters informing you of outstanding VAT and interest — due to GDPR legislation, tax agency employees may not provide information about outstanding amounts in the portal. You must log on to the portal regularly to check your account and pay any outstanding amounts. Set a recurring calendar reminder to check the portal each quarter after filing your OSS return.

For help with access to the E-tax portal, call +45 72 22 26 64. For more on non-Danish business rules, see our Non-Danish Labour Guide →.
