How long will the data used to generate my tax return be kept?

The aforementioned data will be kept for a maximum of ten (10) years after the session has been completed, i.e. after reaching the final stage of the tax report for a given tax year, in order to enable you to justify to the Luxembourg tax authority the calculations used to determine your tax returns.

This remains valid even if you were to terminate your business relationship with Spuerkeess during this period.
