As the Notification Office, OeKB receives tax-relevant data on funds. This is used to determine how the funds are treated for income tax purposes. For calculating the exact amount of capital gains tax to be deducted, the data is published on my.oekb and forwarded to the banks via interfaces.

Reporting data via the OeKB Fund Upload Client

Investment funds, real estate investment funds and alternative investment funds send their tax-relevant data to OeKB through their tax representatives.

The Fund Upload Client is available to you for uploading data subject to notification. You can access the Fund Upload Client via my.oekb after completing the registration. Alternatively, an sFTP-account is available.
