The national schedule has been read against the statute. The regional surcharges are a mechanical extraction from MEF that hasn’t had a commercialista’s eye, and the per-region tax credits in it aren’t modelled. This page is kept out of search until both halves are verified. Nothing here is tax advice.

• The municipal surcharge is not included. Each comune sets its own, and we haven’t ingested them yet. It is small next to the other two but not nothing, and it is the only layer that varies within a region — so these figures rank regions against each other, and are not a final bill for any one address.
• These are gross figures — tax before credits. Detrazioni (the no-tax area, and the income-type credits that taper as income rises) are not modelled anywhere on this site. Real liability is lower, often much lower at modest incomes.
• Regions revise mid-year. MEF publishes a date per region, and this year's range from 2026-01-19 to 2026-06-19, so two rows here can be effective as of different dates.
