Lazio in 2026: one reduced rate up to a threshold, then the full scale from euro one
Italian income tax on a salary is national IRPEF plus a regional and a municipal surcharge, each a separate tax on the same income. The national part is on the Italy salary page; this page is about the regional rule, which for 2026 is unlike anything the other four regions do.
Most regional surcharges in Italy are ordinary marginal scales, each slice of income at its own rate, arithmetic you can do in your head. Lazio’s 2026 rule is not that. If your taxable income for surcharge purposes is at most €28,000, the whole of it is charged at 1.73%. One euro above that and the ordinary Lazio scale applies instead, again from the first euro: 1.73% up to €15,000, then 3.33% on everything else, which is the statutory ceiling for this tax and where Lazio stays all the way to the top.
The threshold is therefore not a bracket boundary. It is a switch between two different scales, and a switch of that kind produces a cliff rather than a step in marginal rate. Our engine cannot model Lazio as a single scale for exactly this reason: it has to pick the scale by looking at your total income first.
What the cliff costs, in euro
At exactly €28,000 of taxable income the regional surcharge is €484.40. At €28,001 the ordinary scale gives €692.43. Lazio softens the landing with a flat credit of €60 for taxable income between €28,001 and €30,000, bringing it to €632.43. One euro of extra income, €148.03 of extra regional surcharge.
Then the credit ends, and ending is itself a step: €699.00 at €30,000 of taxable income, €759.03 at €30,001. Two cliffs inside €2,000 of each other, and neither is visible on a payslip. In salary terms, on an employee pension contribution of 9.19%, the first threshold sits at roughly €30,830 of gross pay and the second at about €33,040. Ordinary Rome salaries, both of them.
The credit cannot turn into a refund. If it exceeds the surcharge due it simply cancels it, and the remainder is gone.
Rome is the one city allowed above the national cap
Italian municipalities may not exceed 0.8% unless a statute expressly says otherwise. Roma Capitale has had that derogation since 2011, and it uses it: 0.9%, against an exemption of €14,000.
That exemption is a cliff too, the same shape as the regional one. At €14,000 of taxable income Rome takes nothing; at €14,001 it takes €126.01, on the whole amount. So a Rome salary can cross two separate cliffs on its way up, one municipal and one regional, at two unrelated income levels.
The threshold is tested before any credit
Both surcharges sit on the same taxable income national IRPEF runs on, deductible items taken off and detrazioni left in place. In Lazio that is not a technicality, it decides which side of the cliff you land on. The income measured against the threshold is your taxable income before any credit, so the employment credit that cuts your national tax by several hundred euro cannot pull you back under the line. The credits settle one question about the surcharges, and only as a yes or no: in a year when IRPEF net of them comes out at zero, neither surcharge is charged at all. Which region and which comune apply is fixed by your tax domicile on 1 January, so a move to Rome during the year changes nothing until the following January.
What changed in 2026
The scale on this page comes from the regional stability law of 31 December 2025 and is set for 2026 through 2028. The reduced rate and the credit, the two things that make this page different from the other four, are drafted for 2026 only, and the previous year’s credit ran over a wider band, so the 2025 figures are not interchangeable with these. On the city side, Rome had adopted no 2026 decision at our last verification: the ministry’s 2026 list shows the marker for a comune that has not deliberated this year, and the previous year’s rate and exemption stay in force by tacit extension. Those are the numbers here, flagged provisional for that reason. A decision published by 20 December would apply retroactively to the whole of 2026.
