On 23 February 2022, the Treasury Department published a bill that would provide a reduced rate of interest on overpayments and tax refunds. The draft bill provides for reduced default interest of 0.15% per month (1.8% per year) on overpayments and tax refunds, retroactive to 1 January 2019.

The bill further provides that the late payment interest rate shall be evaluated and eventually amended for the future every 3 years for the first time in 2026. The draft bill is a response to the decision of the Federal Constitutional Court of 8 July 2021.
