The one scale of the five that is different in every year
National IRPEF is the same in Bologna as anywhere in Italy and is covered on the Italy salary page. What changes with the address is the pair of local surcharges, and Emilia-Romagna’s has a property the other four do not.
Four of the five regions we model publish a scale and leave it there. Emilia-Romagna writes a separate paragraph of its law for each tax year, and one band moves in each of them. The current scale is 1.33% up to €15,000, 1.93% to €28,000, 2.78% to €50,000, and 3.33% above, the statutory ceiling.
The third band is the moving part. It was 2.93% in 2025, it is the figure above for 2026, and the same article already sets 2.63% for 2027. The other three bands do not move at all. So a search result quoting an Emilia-Romagna rate is only meaningful with a year attached to it, and the ministry itself publishes both figures, each under its own year.
Why the year matters more here than elsewhere
Both surcharges are settled by where your tax domicile is on 1 January, and they are not pro-rated. Move to Bologna in April and the whole of that year is billed at your previous address; the first Emilia-Romagna scale you pay is the one in force the following January. In a region where the middle band steps down annually, that is not a technicality. Someone planning a move here in the middle of a year skips a rate and starts on a lower one, which is the opposite of the usual relocation surprise.
Bologna’s exemption, and where it sits among the five
Bologna charges 0.8% with an exemption at €15,000, the second-highest of the five cities behind Milan and ahead of Rome, Naples and Turin. Being an exemption rather than an allowance, it works as a cliff: at or below the threshold the city takes nothing, and one euro above it the rate applies to your whole income rather than to the excess.
At €15,000 of taxable income Bologna takes nothing. At €15,001 it takes €120.01.
The rate for the year meets your income undiminished
Whichever year’s rate applies, it applies to the same taxable income national IRPEF runs on, with deductible items taken off and nothing else. The detrazioni, which do most of the work in an Italian tax calculation, are credits against IRPEF rather than deductions from income, so the surcharge base reaches the regional scale at full size. They settle one question about the surcharges and only as a yes or no: in a year when IRPEF net of its own credits comes out at zero, neither surcharge is charged at all.
What changed in 2026
The middle band came down, by the amount already written into the regional law when it was amended last year, and the ministry’s 2026 table matches it. Nothing else in the region moved. Bologna has not deliberated for 2026 either: the ministry’s list carries the marker for a city that has adopted no decision this year, and the previous year’s rate and exemption stay in force by tacit extension. That is what the calculator applies, and it is flagged provisional for that reason. A city decision published by 20 December would apply retroactively to the whole year.
