R&D tax credit Italy: rates, costs and how to claim in 2026

Here’s a quick way to spot an old guide: if it says Italy’s R&D tax credit is 20%, it’s out of date. That rate stopped after 2022. Today €100 of qualifying research spending earns a €10 credit, and this page was checked on 5 October 2026.

What follows covers the R&D tax credit Italy offers today. How much it pays and where the ceilings sit. What counts as research. Which papers you can’t skip, and what happens if an inspector disagrees with you. New to startup finance? Start from our beginner’s map from zero to a first round.

What is the R&D tax credit in Italy?

It’s not a grant. Nobody sends you money. You earn a credit on your research spending and use it to offset what you owe the state, through form F24, the Italian tax payment form. The rule is Law 160/2019, article 1, paragraphs 198 to 209, amended several times since.

Every business resident in Italy can claim it, whatever its legal form, sector or size, and so can the Italian permanent establishments of foreign companies. Two groups are out: companies in liquidation or bankruptcy, and companies hit by interdictory sanctions under Legislative Decree 231/2001.

How much is it worth in 2026? Rates and ceilings

Activity	Period	Rate	Annual ceiling
Research and development	Up to tax year 2022	20%	€4 million
Research and development	2023 to 2031	10%	€5 million
Technological innovation	2024 and 2025, then ended	5%	€2 million
Innovation 4.0 and ecological transition	2024 and 2025, then ended	5%	€4 million
Design and aesthetic ideation	2024 and 2025	5%	€2 million

Picture a Turin SRL that pays €300,000 in 2026 for its engineers, the parts of two prototypes and a contract with a university lab. Suppose every euro passes the R&D test. The credit is €30,000. It becomes usable from 2027, in three equal yearly instalments of €10,000, offset through form F24.

A footnote on design: the 2026 design credit runs through a MIMIT booking platform with a €60 million budget. It opened on 7 July, and MIMIT’s page says the money was gone within 24 hours. Money like this can vanish in a day, so prepare before a window opens.

What counts as R&D? The Frascati test

The law doesn’t leave “research” to your imagination. It points to the OECD’s Frascati Manual, and a ministerial decree of 26 May 2020 (article 2) lists the activities: fundamental research, industrial research and experimental development. The neighbouring category, innovation, follows the OECD’s Oslo Manual instead.

MIMIT lists six eligible cost categories: staff working directly on the project; depreciation, leasing and other costs of tangible assets and software; contract research done by third parties; consultancy; materials and supplies; and, for R&D only, depreciation of industrial patents and similar rights acquired under licence. Picture a hardware startup: the engineers’ salaries, parts for three prototypes and a university contract all fit.

The line between R&D and ordinary improvement is where checks tend to bite. A specialist guide names the correct qualification of the activity as the main control point. As a rule of thumb, polishing a product with techniques everybody knows is innovation. Work where you honestly can’t tell yet whether it will function sits closer to R&D.

R&D spending also shows up in the test for becoming an innovative startup: at least 15% of the larger of costs and value of production is one of three alternative requirements.

What paperwork do you need?

Two documents are mandatory. First, a sworn technical report for each tax year: what the eligible work was for, what it contained, what came out of it. Your project manager writes it and the legal representative countersigns. If the work was outsourced, the contractor writes it. The second is a certification of the costs by a statutory auditor. A company that doesn’t need an auditor hires one for this, and the fee counts as an eligible cost up to €5,000.

A third step is optional. Article 23 of Decree-Law 73/2022 created a certification of the activities themselves, with rules set by a decree of the Prime Minister of 15 September 2023 and MIMIT decrees in 2024. A certifier from MIMIT’s register, which includes qualified individuals, specialised consultancies, universities and public research bodies, attests that your investments, made or planned, qualify.

That attestation binds the tax authority, except where the facts were misrepresented and the certificate covers an activity different from the one you actually carried out. It doesn’t cover your costs: the amounts and the documents remain your auditor’s responsibility and yours.

What happens in a check? Recovery and risk

The credit is self-assessed: you use it first, and the state checks afterwards. Since a MIMIT decree of 22 July 2025, MIMIT and the Agenzia delle Entrate exchange data to monitor and control certifications. The classic dispute is qualification. A project declared as R&D and requalified as simple innovation means the credit is recovered and sanctions apply, as one specialist guide puts it.

Nothing fancy protects you. You get the certification before you claim, you write the technical report while the work is happening, and your auditor has actually seen the timesheets and invoices. Got a notice? Call a tax professional before you reply.

R&D credit, patent box and other incentives

You can combine the credit with the patent box on the same costs, but the credit’s base is cut by the income tax and IRAP the patent box saves. With a patent box benefit of 30.69% and a 10% credit, €100,000 of qualifying cost saves about €30,690 in tax and earns a credit of roughly €6,931 instead of €10,000. The patent box guide walks through the numbers, and how to patent an idea in Italy covers the IP itself.

A credit won’t stretch your runway overnight: you collect it over three years, and only as far as you have something to offset. If what you need is money for machines, the Nuova Sabatini guide covers the interest contribution on equipment loans. Early-stage? Read the Smart&Start Italia guide too. Aiming at Europe?

Your checklist

1. Start by looking up the rate for your tax year (10% for R&D since 2023, and no, not 20%).
2. Per project, write down the technical question you couldn’t answer yet, who worked on it and how many hours they put in.
3. Timesheets first: one for each person you charge to a project. Then the invoices for outside work.
4. Call your statutory auditor early. Without their certification of the accounts, the credit stays locked.
5. Decide whether the optional certification is worth requesting before you claim.
6. If you own IP, ask your accountant to model the credit together with the patent box.
