The commercial diesel tax credit is the partial rebate on fuel excise that the Italian state grants to road freight transport businesses operating own-account or for hire, for vehicles with mass over 7.5 tonnes. It is regulated by art. 24-ter of the Excise Consolidated Act (D.Lgs. 504/1995) and operational rules from Italy's Customs and Monopolies Agency (ADM). It is filed quarterly via electronic declaration and, in case of insufficient offset, can be refunded as cash. It is the main fiscal lever available to Italian transport businesses to cushion fuel cost incidence.

Who can claim the tax credit
Access to the rebate is not universal: regulation identifies three categories.
- For-hire road freight transport businesses registered in the National Register of road hauliers
- Own-account road freight transport businesses registered in the dedicated list
- Public bodies and businesses operating transport under specific conditions (public-line services, taxis, ambulances)
The technical requirement is vehicle mass: the rebate applies to vehicles with gross mass equal to or above 7.5 tonnes, classified Euro 5 or above. Smaller vehicles or lower emission classes are excluded.
What exactly is rebated
Diesel excise in Italy is composed of various tax components. The tax credit returns a share of the State excise on diesel purchased and used as fuel for qualifying vehicles. The specific per-litre amount is fixed by decree and can vary over time: it is published by ADM at the start of the reference quarter.
Importantly: the rebate applies to diesel actually consumed for freight transport activity, not the entire company fuel purchase. Consumption documentation must be coherent with the declared vehicles and activity.
How the declaration is filed
Filing is fully electronic and follows quarterly cadence.
- Reference period — the just-closed solar quarter (e.g. January-March filed in April)
- Software — dedicated ADM software module, downloadable from ADM portal
- Documentation — fuel purchase invoices, vehicle registration documents, consumption summary
- Outcome — credit is recognized as a tax code usable in offset on F24, or cash refund can be requested in case of insufficient offset
Filing deadlines are published quarterly by ADM. Failure to file within deadlines forfeits the right to the credit for that quarter.
Why the tax credit is no longer enough
The tax credit is structural breathing room, but doesn't solve the structural expensive-fuel problem on Italian road haulage. Three pieces of evidence.
Italian road haulage average margin is low. Industry associations (Confartigianato Trasporti, FAI, Anita) estimate diesel represents between 25% and 35% of total freight transport cost per vehicle. A +10% per-litre variation is not absorbable by margin: it gets passed to the customer or erodes the bottom line.
Volatility is now structural. Between 2021 and 2024 average European diesel price oscillated from ~€1.20 to over €2.00 per litre at the pump, with geopolitical spikes. Multi-year tariff planning is effectively impossible.
The credit is retrospective, not immediate. The carrier prepays fuel and recovers the rebate months later. On owner-operator or small-company cash flow, the gap is non-trivial.
The industrial lever: digitize the supply chain
The fiscal front is governed by law. The operational front is where businesses can actually lower fuel cost incidence per euro invoiced. Three concrete directions.
Reduce empty backhauls. A truck returning empty burns diesel without generating revenue. European average empty-running historically estimated 20-25% of total kilometres (source: Eurostat, structural freight transport data). Every percentage point recovered is saved fuel. A digital exclusive network sharing empty backhauls among participating forwarders delivers concrete reductions.
Cut human time spent on the phone. Every tracking call is time the team isn't spending on route optimization, consolidation, price negotiation. A voice AI like Sara absorbs routine calls and frees hours for high-value activity.
Improve load factor. Knowing in real time that a truck is one-third empty in cargo allows selling residual space. Documentary and operational visibility is the precondition: without it, the decision is made post-hoc, too late.
What changes with HVO, LNG and electric vehicles
The energy transition in European heavy road haulage is in progress but asymmetric. Three main technologies, with different maturity levels.
HVO (Hydrotreated Vegetable Oil). Drop-in synthetic bio-diesel, usable on existing diesel engines without modifications. Declared CO2 emissions reduction up to 90% vs fossil diesel, per supplier data. Availability expanding in Northern Europe, still limited in Italy. Tax-wise, HVO is subject to different excise from fossil diesel and the framing for tax credit must be verified case-by-case.
LNG/Bio-LNG. Liquefied natural gas, refueling infrastructure concentrated on TEN-T corridors. Vehicles available from major European manufacturers (Iveco, Volvo, Scania). Advantages on long-haul, constrained by refueling network.
Electric. Battery traction on light vehicles (< 7.5t) technologically mature. On heavy vehicles (> 18t) commercially nascent, range still constrained, MCS recharge infrastructure under construction. The European AFIR regulation (Alternative Fuel Infrastructure Regulation) imposes network targets for 2030.
For the average Italian forwarder, transition is managed by requesting mixed fleets from network carriers, not replacing everything at once. The exclusive network helps because it highlights which partner carriers have already invested in alternative vehicles.
Driver shortage — a parallel structural phenomenon
In parallel to fuel costs, the sector lives with structural shortage of professional drivers. The figure is collected by IRU (International Road Transport Union) and national associations: hundreds of thousands of qualified drivers are missing in Europe, with worsening forecast to 2030 due to workforce aging and missed generational replacement.
For the forwarder, operational consequences are concrete:
- Rate pressure upward on the most reliable carriers
- Difficulty covering secondary lanes and last-mile
- Growing dependency on subcarriers and structured networks sharing availability
The industrial response is the same as expensive fuel: raise productivity per individual trip. More shipments closed first try, fewer tracking calls, more load factor, fewer empty backhauls. The technology lever is the same fiscal lever: every euro recovered in operations frees margin to absorb price shocks.
FAQ
Which vehicles qualify for the excise rebate?
Vehicles with gross mass equal to or above 7.5 tonnes, in Euro 5 or higher emission class, used for own-account or for-hire road freight transport. Vehicles below threshold or lower emission class are excluded. Reference: art. 24-ter of D.Lgs. 504/1995.
How frequently is the declaration filed?
Quarterly. The declaration is filed electronically with ADM via dedicated software, within deadlines published every quarter. Recognized credit is usable in F24 offset under a dedicated tax code, or can be requested as cash refund in case of insufficient offset.
Does the tax credit apply to HVO and biofuels too?
The framing of HVO and other biofuels relative to State excise is specific and must be verified against current regulation at purchase time. Alignment with fossil diesel regime is not automatic: the company tax advisor is the right interlocutor for the specific case.
How does fuel cost weight into total transport cost?
Italian industry associations (Confartigianato Trasporti, FAI, Anita) estimate weight between 25% and 35% of total trip cost. The share varies with lane length, vehicle type, driving style and average quarterly price. It's the first variable cost item for almost all heavy road haulage businesses.
What can a forwarder do to reduce fuel cost incidence?
Three non-fiscal operational levers: (1) reduce empty backhauls through exclusive networks sharing vehicle availability among participating forwarders, (2) automate tracking calls with voice AI to recover traffic team hours to reinvest in optimization, (3) improve load factor with real-time visibility on shipment and vehicle status.
