- The Federal Constitutional Court has declared late payment interest for periods from 1 January 2014 to be incompatible with Article 3 of the Basic Law (German Constitution), but allowed a transitional period until 31 December 2018 for reasons of fiscal budget protection.
- This acceptance of excessive tax interest until the end of 2018 does not eliminate potential challenges under EU law against the German VAT interest.
- The imposition of late payment interest for VAT due to a delay in deducting input tax caused by the tax office does not violate the principle of proportionality under EU law, as it is not a punitive measure and can be corrected through a discretionary decision.
- The principle of neutrality in VAT does not apply to the imposition of late payment interest.
- In cases where both late payment interest and refund interest are imposed for the same circumstances, the tax office must offset the amounts.
