- For 2026 the Gestione separata contribution is charged on business income up to €122,295 and on nothing above it (INPS circolare 8/2026, § 6.1).
- Below the ceiling an extra euro loses 59.51% — 26.07% to the contribution, then 43% IRPEF and ~2.23% surcharges on the 73.93% that survives. Above it, 45.23%.
- The same €10,000 of work therefore leaves €4,049 to someone whose year ends on the ceiling and €5,477 to someone already past it.
- The €2,500 of pension contribution on that €10,000 is not credited either: comma 18 caps «la base contributiva e pensionabile», both halves of it.
- The ceiling exists only for people with no Italian contribution seniority before 1 January 1996, and not for professions with their own fund.
Two freelancers in Milan each win the same €10,000 contract this autumn. One expected €112,295 of business income for the year, so the new work carries them to exactly €122,295. The other was already at €130,000. After the contribution, income tax and the local surcharges, the first keeps €4,049 of that €10,000. The second keeps €5,477 — €1,428 more, for the identical piece of work.7
The line between them is €122,295, the ceiling INPS set for 2026 on the income the Gestione separata contribution is charged on. Below it the contribution takes 26.07% of every euro before income tax touches what is left. Above it there is no contribution at all.12
Where the contribution stops
Section 6.1 of the INPS circolare for 2026 says it in one sentence: for the year the ceiling of article 2, comma 18 of law 335/1995 is €122,295.00, and the year’s rates apply to income «fino al raggiungimento del citato massimale» — up to that ceiling and no further. A professional with no other compulsory pension cover pays 26.07% on the income below it: 25.00% towards the pension, 0.72% for maternity, sickness, hospital stays and parental leave, and 0.35% for ISCRO.1
The ceiling is not for everyone. The comma that creates it applies to people «privi di anzianità contributiva» who joined a compulsory pension scheme from 1 January 1996 onwards, and to those who opted into the contributory system. Somebody who was already paying Italian contributions in 1995 is outside it. Somebody who arrived in Italy and first registered a partita IVA at any point in the last thirty years is inside it.2
What the next euro costs
Contributions come off total income before income tax is worked out, under article 10 of the income tax code, so below the ceiling an extra euro is taken twice: 26.07 cents to INPS, and then the 43% top rate plus roughly 2.23% of regional and municipal surcharge on the 73.93 cents that survive. That is 59.51 cents gone. Above the ceiling the first bite is missing and the same euro loses 45.23 cents.346
So the heaviest rate an Italian freelancer on this scheme meets is not at the top of the scale. It runs from €67,632 of business income — the point where the taxable remainder reaches the 43% band — up to the ceiling, and then it falls by 14.28 points and stays there. Nothing further up the scale puts it back: article 11 has no bracket above 43%. The credit for self-employment income does not soften the band either: article 13, comma 5 of the income tax code zeroes it above €50,000 of total income, well below where any of this happens.57
Computed from the 2026 circolare and the income tax code, walked in single euros: contribution 26.07% up to €122,295, deducted from total income, then IRPEF and a 2.23% average local surcharge. Drawn at the two exact breakpoints rather than sampled, and as two separate lines with a gap, because the ceiling is a step and not a slope. No deductible costs.71
The pension side of the line
A lower rate above the ceiling looks like a straightforward gift to the higher earner, and the first thing to check is whether it is one. It is not, or not entirely. Comma 18 sets the ceiling on «la base contributiva e pensionabile» — the contribution base and the pension base together. The euros above the line pay nothing and earn nothing.2
On the two €10,000 contracts, that is €1,428 of extra cash for the second freelancer and €2,500 of pension contribution never credited to them, since 25 of the 26.07 points is the pension slice. Whether that trade is good depends on what the Italian pension system will return on €2,500 of contribution paid in 2026, which is a different piece of arithmetic and is not this one. What can be said now is that the choice is not offered: crossing €122,295 makes it automatically.
| The €10,000 | Income band | Rate on it | Kept | Pension credited |
|---|---|---|---|---|
| ends on the ceiling | €112,295 → €122,295 | 59.51% | €4,049 | €2,500 |
| starts above it | €130,000 → €140,000 | 45.23% | €5,477 | €0 |
Net income after the contribution, IRPEF, the self-employment credit and a 2.23% average local surcharge, computed at each end of the two blocks and differenced after rounding. Pension contribution credited is 25% of the income under the ceiling.71
What €300,000 actually pays
Run the same rules to €300,000 of business income and the contribution is still €31,882.31, because it stopped at the ceiling. Income tax on the €268,117.69 that remains is €107,490.61, the surcharges add €5,979.02, and €154,648.06 is left — 51.5% of the €300,000. Charge the contribution on the whole €300,000 instead, changing nothing else, and the same person keeps €129,274.38. The ceiling is worth €25,373.68 a year at that income, which is a measure of the ceiling’s size rather than a saving anybody made: no version of the rules charges the contribution above it.7
Contribution, tax and the marginal rate, €50,000 to €200,000 (CSV)303 rows — €500 steps, plus the ceiling itself and the €112,295 compared from: contribution with the 2026 ceiling applied, IRPEF base, IRPEF, surcharges, net income, average rate and marginal rate.What this does not settle
The surcharge is an average. Regional and municipal rates vary, and recomputing at the ends of the statutory range moves the step to 14.68 points at the low end and 13.99 at the high one, against 14.28 on the average — the level moves, the shape does not. Every figure here assumes no deductible costs, the convention this blog uses throughout, so a person with real costs reaches the ceiling on higher billing than these numbers suggest.
None of it applies to a freelancer whose profession has its own fund — a lawyer, an architect, an accountant — because those funds set their own ceilings and their own rates. Nor to anyone on the flat-rate regime, whose revenue cannot reach €122,295 of income while they stay in it. One oddity the arithmetic throws up is worth naming and not building on: a €50 step in the self-employment credit at €17,000 of total income means a single euro there carries a rate in the thousands of per cent. It is one euro, and it is a rounding rule rather than a policy, which is why it sits in this paragraph and not in the chart.5
