“Can I take several incentives together?” is the question that comes right after understanding which measures exist. The answer — typical of subsidised finance — is “it depends, and it has to be calculated”. Combining the Ecobonus, a regional grant and the Nuova Sabatini on the same renewal is possible in some cases and prohibited in others, and getting the stacking calculation wrong is not a formality: it can lead to the revocation of the contribution years later, during an audit.
This article explains the three rules that govern stacking incentives on commercial vehicles — the de minimis regime, the no-double-financing rule and the aid-intensity ceilings — so you know which questions to ask before signing, and when you need an advisor.
Why incentives are “State aid”
Almost all public contributions to businesses — Ecobonus, regional grants, PNRR bonus — are technically State aid, and as such subject to the European rules that limit their amount and stacking. Most of these measures are granted in one of two ways:
- under the de minimis regime, i.e. within a ceiling of “small-scale” aid a company can receive in a given period;
- under an exemption regime (the General Block Exemption Regulation, GBER), which allows higher amounts but with specific conditions and maximum intensities.
Understanding which regime each measure is granted under is the first step to knowing whether two incentives can coexist. It’s information found in the text of the call or decree, not in the headlines.
Rule 1 — The de minimis ceiling: €300,000 over three years
From 1 January 2024, Regulation (EU) 2023/2831 set the ordinary de minimis ceiling at €300,000 per “single undertaking” over a three-year period (it was €200,000). Three practical aspects to know:
- Rolling period, not calendar year: the three years are calculated “backwards” from the grant date of each new aid (a rolling 36 months), not by fiscal year. Each aid stays in the count for 36 months from the date it was granted.
- “Single undertaking”: the ceiling isn’t per individual company but per the group of linked enterprises (control, qualified holdings). Two companies controlled by the same enterprise share the same cap.
- National Aid Register (RNA): every de minimis aid must be recorded in the RNA, which has become the official reference for verifying the residual ceiling before granting a new contribution. Before requesting an incentive, it’s worth knowing how much ceiling you’ve already used with other recent aid.
For an SME that has received other contributions over the last three years (digitalisation, training, other grants), the de minimis ceiling may already be partly occupied: a factor to verify before counting on a new incentive.
Rule 2 — The no-double-financing rule on the same cost
It’s the most important principle and the most misunderstood: the same euro of spend can’t be covered twice by two different aids. Translated to vehicles:
- two contributions both acting on purchasing the same vehicle are, as a rule, not combinable. Many calls say so explicitly (“not combinable with other national or European incentives for purchasing the same vehicles”);
- conversely, aids acting on different cost components can in several cases coexist. This is why the Nuova Sabatini — which subsidises the financing (the interest), not the asset’s price — can in several cases sit alongside a purchase contribution, always within the ceilings. We cover this in the guide to the Nuova Sabatini for commercial vehicles.
The right question to ask isn’t “are these two incentives combinable?” in the abstract, but “which cost component does each act on?”. If they act on the same one (the vehicle’s price), stacking is probably excluded; if on different ones (price vs. financing interest), it needs checking but is more often possible.
Rule 3 — Overall aid intensity
Even when stacking is allowed, there’s a cap on aid intensity: the sum of all aid received for an investment can’t exceed a certain percentage of the eligible cost. This is why, even by combining several measures, you never get to cover 100% of the spend with public money: the European rule requires a share to remain on the company’s account.
This is why stacking must always be calculated, not just verified in principle: you need to sum the amounts, relate them to the eligible cost and check you don’t exceed either the de minimis ceiling or the maximum intensity of the measure under the exemption regime.
⚠️ This article explains general principles; it doesn’t replace analysis of the specific case. Stacking rules depend on the regime and the text of each call, and an error can lead to revocation of the contribution with repayment and interest. For applications combining several incentives, get help from a subsidised-finance advisor or the bank.
An example of reasoning (not a definitive calculation)
A freight-transport SME wants to renew three electric vans, financing them on lease. The stacking reasoning, in order:
- Purchase contribution: check which one applies (Ecobonus, regional grant, possible future DPCM) and under which regime it’s granted. If two act on purchasing the same vehicles, it picks one.
- De minimis ceiling: if the chosen contribution is de minimis, check the RNA for how much ceiling it has already used in the last 36 months.
- Financing: assess the Nuova Sabatini on the lease, which acts on interest — a different component from the price — checking stacking with the purchase contribution with the bank.
- Overall intensity: sum all the aid and check you don’t exceed the ceiling relative to the eligible cost.
The outcome depends on the specific regimes and texts: it’s exactly the kind of check worth doing before signing the order, with someone who knows the field.
The bottom line
Stacking incentives isn’t a matter of “how many can I take”, but of three constraints to respect: the de minimis ceiling (€300,000 over three rolling years, per single undertaking), the no-double-financing rule on the same cost, and the aid-intensity cap. The most useful practical rule is to reason by cost component: measures acting on the vehicle’s price rarely add up to each other, while a measure on the price and one on the financing can often coexist.
Before setting up a renewal that combines several incentives, start from the full picture: which purchase contribution applies (see the 2026 commercial vehicle incentives guide or the check tool), then the financing lever, and finally the stacking calculation with an advisor. And remember the goal isn’t to maximise the aid on a single vehicle, but to renew the right vehicles: a decision made on total cost of ownership, not on the sum of the bonuses.
Frequently asked questions
Can I combine the Ecobonus and a regional grant on the same van?
As a rule no, if both act on purchasing the same vehicle: many calls explicitly prohibit stacking with other national or European incentives for the same vehicles. Some regional calls do, however, provide specific stacking clauses: always read the text of the individual call.
What is the de minimis ceiling and how do I know how much I’ve used?
It’s the cap on small-scale aid a company (or group) can receive: €300,000 over three rolling years from 1 January 2024. You check it in the National Aid Register (RNA), where de minimis aid granted to your company is tracked. The advisor or bank checks it before filing the application.
Does the Nuova Sabatini use up the de minimis ceiling?
It depends on the regime under which it’s granted. The Sabatini acts on financing, on a different component from the asset’s price, which makes it compatible in several cases with a purchase contribution; the impact on the ceiling and aid intensity must, however, be verified case by case with the bank/intermediary.
What do I risk if I get the stacking wrong?
Exceeding the ceilings or an unauthorised double financing can lead to revocation of the contribution, with an obligation to repay plus interest, even years later during an audit. This is why stacking must be calculated and documented beforehand, not improvised.
