Tax residency self-certification
We are obliged to determine the country of tax residence of our corporate customers. If necessary, we will report them to the Finnish Tax Administration.
In addition to the basic details about your company, we ask you to provide the following information in the tax residency self-certification: country of tax residence and tax identification number (TIN) issued by a foreign authority.
The Finnish Tax Administration shares the information annually with authorities of other countries. The information to be reported includes saving and investment products and profits from these, and the balances of your corporate accounts. Our obligation to report is based on legislation and international treaties signed by Finland.
Please fill in the tax residency self-certification as instructed.
You can return the tax residency self-certification by online message on OP’s service or by encrypted email to verotusmaailmoitus@op.fi. Instructions on sending secure email can be found here.
