Renting a car for a business trip can be a particularly practical solution when employees, collaborators or professionals need to travel between airports, clients, company offices and destinations that are not easily accessible by public transport.

This is especially relevant during a business trip to Sardinia, where having a vehicle available can significantly reduce travel times between different locations.

From a tax perspective, however, one of the most common questions is: is the cost of a rental car used for a business trip tax-deductible? And can the VAT be recovered?

The answer is yes, but there is no single percentage that applies in every situation.

The tax treatment depends on who uses the vehicle, why it was rented and the relationship between the car and the activity being carried out.

In particular, it is important to distinguish between:

  • a car rented for a specific business trip by an employee or collaborator;
  • a car rented and normally used by a company or professional;
  • a vehicle used exclusively as an essential business asset;
  • a company car made available to an employee for both business and private use;
  • a rental vehicle used by commercial agents or sales representatives.

Below we look at the main rules and the documentation that should be kept.

Tax deductibility of a rental car used for a specific employee business trip

This is the most important case to distinguish from the ordinary business use of a vehicle.

Article 95, paragraph 3 of the Italian Income Tax Code, known as the TUIR, specifically regulates situations in which an employee or collaborator is authorised to use a rental car for a particular business trip.

In this case, the cost incurred by the company is deductible within a limit calculated by reference to rental rates for cars with a fiscal horsepower not exceeding 17 fiscal HP, or 20 fiscal HP for diesel vehicles.

Therefore, the standard rule:

“20% of the rental cost is deductible”

does not automatically apply.

Business trips are subject to a specific tax regime.

In practical terms, if a company authorises an employee to rent a car in order to travel, for example, from Olbia to several clients or company locations during a business assignment, the cost may be deducted according to the rules set out in Article 95.

If a higher-category or more powerful vehicle is selected than the tax benchmark allows, the portion of the cost exceeding the applicable fiscal limit may not be deductible.

A practical example

Suppose a company sends one of its employees to Sardinia for three days to meet several clients.

The company rents a car for the duration of the business trip.

The actual rental cost should not simply be subjected to the standard 20% deductibility rule that applies to many company cars.

For tax purposes, the deductible amount must instead be assessed against the limit set by Article 95 of the TUIR, based on the average rental rates for vehicles falling within the fiscal parameters established by law.

This is why the distinction between:

a car rented for a specific business trip

and

a vehicle normally used by the company

is fundamental.

Does the rule also apply to business trips abroad?

Yes.

The rules have also been interpreted by the Italian tax authorities as applying where an employee is authorised to use a rental vehicle for a specific business trip abroad.

The same general approach has also been recognised for certain chauffeur-driven rental arrangements.

The key factor remains the existence of a specific business trip connected with the employee’s work activity.

Business travel and ordinary company use of a vehicle are not the same thing

This is where confusion often arises.

Article 95 of the TUIR regulates expenses incurred in connection with employee business trips.

Article 164 of the TUIR, on the other hand, regulates more generally the costs of vehicles used in business or professional activities.

To understand which tax regime applies, the first question should therefore be:

was the car rented specifically for a particular employee business trip, or is it a vehicle normally used by the company?

In the first case, the specific rules on business travel apply.

In the second case, the general rules governing business vehicles will normally be relevant.

Ordinary car rental for companies and professionals

When the vehicle is not rented specifically for an employee’s business trip but is normally used as part of a business or professional activity, Article 164 of the TUIR becomes the main reference.

For passenger cars that are not used exclusively as essential business assets, the standard deductibility rate is 20%.

For car leasing and rental costs, there is also an annual tax limit of €3,615.20, which must be adjusted according to the actual period during which the vehicle is used.

This means that the 20% rate is not necessarily applied to the full amount actually paid if the rental cost exceeds the amount recognised for tax purposes.

This limit applies to the general rules governing business vehicles and should not be confused with the rules for a specific employee business trip.

What if a professional rents a car for their own business trip?

If a self-employed professional personally rents a car to visit a client or attend a business appointment, the employee business-trip rules under Article 95 do not automatically apply.

The cost must instead be assessed under the tax rules applicable to professional activities and vehicles used in carrying out that activity.

In general, for a passenger car that is not used exclusively as an essential business asset, Article 164 applies, with 20% deductibility within the relevant fiscal limits.

This is an important distinction: the fact that a journey has a professional purpose does not automatically mean that every rental falls under the employee business-trip rules of Article 95.

When is car rental 100% deductible?

Full deductibility is available where the vehicle is used exclusively as an essential asset for the company’s core business activity or is intended for public use.

The concept of exclusive business necessity is, however, much stricter than it may initially appear.

It is not enough for a car to be used frequently for work.

According to the interpretation adopted by the Italian tax authorities, the vehicle must be essential to such an extent that the business activity could not be carried out without it.

Typical examples include vehicles used by car rental companies as part of their rental activity or certain vehicles that are indispensable to the specific business carried out.

A car used by a company simply to visit customers or attend commercial appointments does not automatically qualify as a 100% deductible business asset.

Cars made available to employees for both business and private use

Another separate situation is a vehicle made available to an employee for both work and personal use.

Where the car is assigned for mixed business and private use for most of the tax period, Article 164 of the TUIR provides for 70% deductibility of the related costs.

This rule is often confused with the rules on business travel, but it concerns a completely different situation.

A vehicle rented for three days during a business trip does not become a company car assigned for mixed use.

Commercial agents and sales representatives: what rules apply?

Commercial agents and sales representatives benefit from a more favourable tax regime than most companies and professionals.

The deductibility of vehicle costs can reach 80%.

For passenger car leasing and rental agreements, the maximum annual amount recognised for tax purposes is €5,164.57, compared with the general limit of €3,615.20.

The limit must be adjusted according to the actual period for which the vehicle is used.

Therefore, the previous reference to 20% deductibility for agents and representatives would be incorrect: the specific regime under Article 164 provides for an 80% deduction.

Car rental and VAT: how much can be recovered?

Tax deductibility and VAT recovery are two entirely different concepts.

The first affects taxable income.

The second concerns the VAT paid on the rental service.

For road vehicles that are not used exclusively for business or professional purposes, Italian VAT rules generally allow 40% VAT recovery.

This restriction does not apply when the vehicle is used exclusively for business purposes, provided that the exclusive use is genuine and can be demonstrated.

In such cases, the VAT may be fully recoverable.

Specific favourable rules also exist for commercial agents and sales representatives and for businesses whose core activity consists of selling or renting vehicles.

Can VAT be recovered in full if the car is rented only for one business trip?

This is an area where automatic assumptions should be avoided.

The fact that a vehicle is rented exclusively for a particular business trip can be an important factor in demonstrating professional use.

However, for full VAT recovery, the vehicle must actually be used exclusively for business or professional purposes.

For this reason, it is advisable to retain consistent supporting documentation showing:

  • the reason for the business trip;
  • the duration of the trip;
  • the destination;
  • the employee or collaborator authorised to use the vehicle;
  • the rental invoice;
  • any internal company documentation relating to the assignment.

If exclusive professional use cannot be adequately demonstrated, VAT recovery will generally remain limited to 40%.

How important is documentation?

Very important.

An expense incurred for a business trip should be clearly traceable to the company’s activity.

It is therefore useful to keep:

  • the rental invoice correctly issued to the company or person bearing the cost;
  • the business-trip authorisation or equivalent document;
  • the name of the employee or collaborator travelling;
  • travel dates;
  • destination;
  • the business purpose of the trip;
  • documentation relating to any additional expenses.

The clearer the connection between the rental and the business trip, the easier it is to support the chosen tax treatment.

What does “business trip” mean for tax purposes?

The fiscal meaning of a business trip also deserves attention.

For employees, Article 51 of the TUIR distinguishes between travel outside the municipality where the normal workplace is located and travel within the same municipality.

For business trips outside the municipality, properly documented reimbursements of travel and transport expenses may qualify for the tax treatment provided by the relevant rules.

Ordinary commuting between home and the normal workplace should not automatically be treated as a business trip.

A business trip is connected with travel required by the employer in order to perform work in a location other than the employee’s normal workplace.

What is the difference between a car rented directly by the company and reimbursement to the employee?

A company can organise business travel in different ways.

It may rent the car directly and have the invoice issued in its own name.

Alternatively, where authorised, the employee may pay the rental cost and later claim reimbursement under the company’s travel-expense procedure.

In both cases, the documentation should clearly show the connection between the expense and the specific business trip.

From an administrative perspective, having the invoice issued directly to the company may simplify both accounting and VAT treatment.

Fuel, parking and tolls: do they follow the same rules?

Not necessarily.

The rental agreement is one type of cost, while fuel, parking, tolls, taxis, meals and accommodation may each be subject to specific tax rules.

From 2025, new traceable-payment requirements for certain expenses incurred during business trips in Italy also came into force, particularly for meals, accommodation and certain non-scheduled transport services such as taxis and chauffeur-driven hire services.

The Italian tax authorities have clarified that, where applicable, traceable payment can affect both the tax treatment of employee reimbursements and the deductibility of the related expense for the company.

It is therefore advisable for companies to organise business trips using traceable payment methods and to retain supporting documentation.

What about additional rental services?

A rental agreement may also include additional services such as:

an additional driver, extra protection, child seats, satellite navigation, delivery to a different location or other optional services.

The tax treatment may depend on how these amounts are shown in the agreement and on the invoice.

In particular, where the rental contract clearly separates the vehicle rental charge from additional services, the various components may need to be considered separately when applying the relevant deductibility rules.

For this reason, it is preferable for the rental agreement and invoice to clearly show how the total price is made up.

Example: a business trip to Sardinia

Suppose a company based in Milan sends an employee to Sardinia for four days.

The employee lands in Olbia and needs to meet clients in Olbia, Arzachena and Nuoro.

The company therefore rents a car for the duration of the assignment.

In this case, the vehicle is not a company car normally used throughout the year, but a car rented specifically for a business trip.

The deductibility of the cost should therefore be assessed under the specific rules in Article 95, paragraph 3 of the TUIR.

The company should keep the invoice, business-trip documentation and any other records that clearly connect the rental to the employee’s work activity.

Frequently asked questions about the deductibility of car rental on business trips

Is car rental for a business trip 100% deductible?

Not automatically.

For a specific employee business trip, Article 95 of the TUIR sets a particular deductibility limit based on rental rates for defined categories of passenger cars.

Does the 20% deductibility rule always apply?

No.

The 20% rule is the general rule under Article 164 for certain passenger cars used in business or professional activities.

Where the vehicle is rented specifically for an employee business trip, a separate rule applies.

Is VAT on the rental recoverable?

Yes, within the limits set by VAT legislation.

Where the vehicle is not used exclusively for business purposes, VAT recovery is generally limited to 40%.

Where exclusive professional use can be demonstrated, the conditions for full recovery may be met.

Can a professional deduct the full cost of a rental car used to visit a client?

Not simply because the journey has a professional purpose.

A professional personally using the vehicle will generally fall under the rules in Article 164 unless specific circumstances apply.

Can commercial agents and sales representatives deduct more?

Yes.

For commercial agents and sales representatives, Article 164 allows deductibility of up to 80%, with an annual rental-cost limit recognised for tax purposes of €5,164.57.

Renting a car for a business trip

The tax treatment of a rental car therefore depends on the specific circumstances.

The right question is not simply:

“how much of the rental cost can I deduct?”

but rather:

“who is using the car, why was it rented and which tax rule applies to that specific situation?”

Distinguishing between an occasional business trip and a vehicle that is normally used by the company helps avoid mistakes and ensures that the correct tax treatment is applied.
