InvestorTax@OneClick - Tax Compliance Tool for institutional investors of investment funds

Fast calculation of tax values of investments

Challenges for institutional investors in fund taxation

Institutional investors, especially (life) insurance companies, regularly have a wide range of investments (funds), which poses special challenges in the context of the annual tax compliance processes. Extensive calculations based on the individual fund transactions are required to determine the tax values. This is especially true in the context of investments in (special) investment funds according to the new reform of the German Investment Tax Act and to calculate and develop the transitional values. Fund investors face the following challenges in particular:

The solution - The new German Investment Tax Act (InvStG) made easy

InvestorTax@OneClick offers you a simple and tool-based solution for the determination of tax key figures according to old and new German Investment Tax Act (for the purposes of tax returns, annual audits or tax audits). All you have to do is provide us with the transaction data and you will then receive the necessary calculations and results clearly prepared and presented in detail.


We use a standardized and automated process for data processing, without media breaks or manual intervention. Processing costs and susceptibility to errors are sustainably reduced.

If the tax-relevant values of the investment funds are not publicly accessible (e.g. for special investment funds), we define a catalog with relevant taxation data (so-called investor reporting) together with you and design the process of data delivery by the capital management company or the fund. All you have to do is provide us with the transaction data. We look forward to help you with the preparation.

As a result of our work, you will receive from us all investor-specific taxation bases for your investment funds: balance sheet and off-balance sheet corrections as well as the appropriate further developments. We are happy to adapt the scope and level of detail of the analyses to your needs.
