Italy has published the Decree of 13 December 2021 from the Ministry of Economy and Finance in the Official Gazette, which sets the legal (statutory) interest rate at 1.25% (up from 0.01%) with effect from 1 January 2022. For tax purposes, the rate may be used in relation to the taxation of interest income as a presumed rate on loans if the rate has not been agreed to in writing.
