Italian biennial tax agreement deadline set for November 2, 2026

Businesses and self-employed professionals in Italy have until November 2 to opt into the biennial preventive tax agreement. The Revenue Agency has issued requirements and instructions, including benefits linked to ISA scores. The measure is aimed at simplifying tax compliance for eligible taxpayers.
Italy's Revenue Agency has outlined how eligible businesses and self-employed professionals can join the biennial preventive tax agreement. The opt-in window closes on November 2, 2026.
The arrangement is intended to make tax compliance simpler for those who qualify. Officials have also tied certain advantages to ISA scores, and the agency has published the conditions and procedural steps taxpayers must follow.
The change could affect businesses and self-employed professionals by offering a longer planning horizon for tax obligations, potentially easing administrative pressure for those who opt in. Because advantages are linked to ISA scores, take-up and perceived benefit may vary across eligible taxpayers. The wider effect on compliance culture and administrative workload may depend on how clearly the Revenue Agency's instructions are understood and applied.
