August 20 serves as a major fiscal deadline in Italy, affecting a wide range of entities including businesses, professionals, and tax withholding agents. The deadline involves approximately 140 different types of fiscal and contributory payments.

Obligations include periodic VAT settlements for both monthly and quarterly filers, annual VAT installments, and various tax installments under the 2026 Redditi and IRAP models. The deadline also encompasses withholdings on employment and self-employment income, the Tobin tax, and substitute taxes on capital gains and asset management. Payments are generally processed via the F24 model. While payments made between August 1 and August 20 can be completed without penalties, certain subjects may face a 0.80% surcharge if payments are made after the extension period.
