New for 2026: what changes with the DM 10 March 2026 →
Three steps.
One ADM receipt.
What is the AD-1 declaration?
AD-1 is the declaration every power plant in Italy files with the ADM to report electricity subject to excise duty under Italian excise law (TUA). Since 2026, it's filed twice a year instead of once. Full guide to the AD-1 declaration →
The AD-1 declaration should not be this hard.
The ADM portal is a maze
U2S is slow, manual data entry is full of pitfalls and the error messages returned by the system are incomprehensible. The same struggle every year, with deadlines creeping closer.
A spreadsheet between you and the ADM
The AD-1 declaration requires precise calculations: rates by consumption bracket, partial exemptions, different declarant categories. One mistake in the sheet means a wrong declaration - and a potential ADM penalty.
From 2026 declarations have doubled
D.Lgs. 43/2025 turned the annual declaration into two semi-annual ones. The same work, twice a year. H1 by end of September, H2 by end of March.
Deklara was built to solve exactly these problems.
Three steps. Declaration submitted.
From your ADM licence number to S2S submission - no sales call required.
