Italy takes three bites out of the same money, and none of the three knows the other two exist. The company pays IRES on its taxable income and IRAP on a wider base of its own. Then you pay a flat, final tax on the dividend that comes out of what survived. Nothing from the first two reduces the third. The total lands close to half the profit, which is the highest of the four countries on this site.
The chain, one layer at a time
Start with EUR 200,000 of company profit in Milan and walk it down.
Layer one, IRES. A flat 24% of taxable income, the same for every company. There is no small-company rate and no first-year rate in 2026.
Layer two, IRAP. 3.9% in Lombardy, and up to 4.97% in Campania. It is a separate tax on the value of production, not a slice of IRES, and the calculator charges it on the same profit figure for want of anything better to charge it on.
On 200,000 that is 48,000 of IRES plus 7,800 of IRAP in Milan, so 144,200 leaves the company level intact. In Naples the IRAP line is 9,940 instead and 142,060 survives.
Layer three, the dividend. Whatever is left is distributed and taxed at 26%, withheld by the company and final. It never enters your return, so nothing is settled later and no other income changes it.
That takes 37,492 in Milan and 36,935 in Naples, leaving you 106,708 and 105,124 respectively. As a share of the original profit: about 46.6% gone in Lombardy, about 47.4% in Campania. The region moves the total by roughly a point, and it moves it at the company level, before the dividend tax gets its turn.
Nothing is netted off, by design
This is a classical system and the two levels are strangers. The IRES and IRAP the company paid are simply spent; the dividend is then taxed as if it were fresh money. Because the withholding is final, the dividend never appears in your tax return, so there is no personal liability a credit could reduce even if the law wanted to give you one.
It did once give something. Until the 2018 reform, a qualified holding put only part of the dividend into the taxable base, which softened the double charge for exactly the founder-sized shareholding this page is about. That sentence was repealed and the consolidated text now carries the repeal notice in its place. The exclusions that remain, including the participation exemption, relieve a company that holds shares in another company, not a person.
Spain and Portugal do the same thing to their resident founders, so the double charge is not an Italian eccentricity. What is Italian is the size of the first layer, because there are two taxes in it.
For scale: a Polish founder on the small-taxpayer route gives up somewhere in the mid-twenties as a share of profit, a Spanish one lands in the thirties to forty, and a Portuguese one sits near forty on the flat dividend route. Italy is the most expensive chain of the four, and the gap is opened at the company level, not at the dividend.
One line the region decides, and two it does not
IRES is national. The dividend rate is national. IRAP is not, and it is charged on the widest base of the three, so the whole geographic question in an Italian founder’s tax bill runs through that one line. Lombardy, Piedmont and Emilia-Romagna sit at the national ordinary rate; Lazio sits exactly on the ceiling for regional variation; Campania sits above that ceiling, which it is permitted to do because it is under a healthcare deficit recovery plan.
The chain is optimistic, and here is the direction
The IRAP layer above is charged on your taxable profit. The real IRAP base is the value of production, which does not let you deduct interest on your loans, provisions, write-downs, temporary and agency labour, or the fee you pay yourself as an administrator under a coordinated-collaboration mandate. For an owner-managed S.r.l. those are not edge cases, they are the normal cost structure, so the real base is bigger than profit and the real IRAP bill is higher than layer two shows.
Pulling the other way, and by less: the IRAP attributable to permanent staff is deductible from the corporate income tax base, and a further tenth of the IRAP bill is deductible as the part referable to interest. We do not reduce the IRES base by either, so layer one runs slightly high. For a company with real payroll the two errors partly cancel. For a founder company with no staff and a director’s fee, they do not.
What you pay yourself is not in this chain
The chain prices one route: profit, taxed twice at company level, then distributed. It contains no line for what you take out as pay for actually working there, and pay carries social contributions that no part of the arithmetic above accounts for.
The IRAP asymmetry matters when you compare the two routes. A fee paid to yourself as an administrator under a coordinated-collaboration mandate stays inside the IRAP base, so it does not shrink layer two by a cent. Whatever the pay route saves you, it does not save you that. Price it properly on the income tax calculator instead of assuming a salary is deductible against everything.
The alternative this page does not price
An S.r.l. with no more than ten individual shareholders and revenue below the statutory threshold may elect fiscal transparency. The company then drops out of corporate income tax and the profit is taxed directly on each shareholder’s personal income tax, with nothing further due when it is distributed: one layer instead of the stack above. Whether it beats this chain depends on where the profit lands on your own scale, which runs 23%, 33% and 43% before regional and municipal surcharges, and it comes with conditions of its own. This page models the default arrangement, which is what almost every S.r.l. is on.
What else the chain leaves out
- A company producing in more than one region splits the value of production between them and each region charges its own rate. We apply one region to the whole profit.
- An asset-heavy or dormant company that fails the non-operating test pays corporate tax with a surcharge of ten and a half percentage points on income deemed from its assets, which cannot be derived from a profit figure.
- Sector uplifts. Energy businesses pay two IRAP points more for 2026 and 2027, banks and insurers pay more of both taxes, and Emilia-Romagna has raised its rate for a list of activities. The chain charges ordinary rates to everyone.
- Anything before the profit line. We take the taxable profit you enter and trust it: which costs are deductible, and how the profit got that size, is your accountant’s question and not this page’s.
The two calculators behind this page are the corporate tax and the dividend tax. Each explains its own layer in detail. This page is only where they meet, and where the arithmetic stops being reassuring.
