The system of penalties/surcharges for late submission without prior requirement by the Tax Authorities (Art. 27.2 LGT 58/2003) has been modified by the Act 11/2021 published on Saturday 10 July 2021 in the Spanish Gazette (BOE) and came into force on Sunday 11 July 2021.
The new rule brings changes to the penalties/surcharges system. The new surcharge is 1% for delays of less than a month, plus an additional 1% for each full month of delay that follows. The rate increases again after a 12 month period to 15% plus an additional late payment interest charge.
