Instructions on granting a mandate (e-Authorisation)

The Web Service enables entrepreneurs to authorise other companies to act on their behalf in the MyTax service. The OP Light Entrepreneur service uses MyTax to manage tax matters on behalf of private traders. That’s why we need a mandate from our service users.

After signing the power of attorney, authorise us in accordance with the instructions given below. If you stop using the OP Light Entrepreneur service, you can also terminate the mandate.

The mandate is granted to Pivo Wallet Oy on behalf of your company. Pivo Wallet Oy is part of OP Financial Group. It will only take you a few minutes to grant the mandate. To do so, you will need online bank user identifiers for logging into the service. Start by opening the front page of then follow the instructions given below. You must follow the instructions precisely. You can only use our service if you grant us a mandate to act on behalf of the correct private trader (business ID).

I have granted a e-Authorisation (mandate) but cannot access my user account. What’s the problem?

There is a delay of around an hour in the registration of a mandate, after which you can start using OP Light Entrepreneur. The most common problems preventing a mandate from appearing in the service are listed below.

Here are the most common reasons if the authorization does not appear in the service:

  1. The mandate assignee was incorrectly typed: Piwo Wallet Oy or other versions of the company’s name will not work, the correct assignor’s name is "Pivo Wallet Oy".
  2. The mandate is granted in the role of a private person. Check that you granted the mandate when in the role of a company.

Checking a mandate

Check mandates you have granted via the service in the following way:

  • Log into the service. You will need bank user identifiers to log in.
  • Then click on "Granted mandates"
  • Above the list of mandates is a button, "Company’s mandates". Click this to change your representative role to company.
  • Click the assignee’s name to see the details of all mandates on the new list

Why are mandates needed?

A e-Authorisation (mandate) is required for using our service, since we cannot manage taxation on your behalf without it.

I can’t access mandate granting on the website? What should I do?

Online bank user identifiers

You will need valid online bank user identifiers to grant a mandate.

If you cannot log into the service with your online bank user identifiers, the reason may be that guardianship, for example, prevents you from acting on your own behalf. In such a case, please contact our customer service.
