Taxation of passenger cars: company car or personal car?

The taxation of passenger cars in Estonia mainly depends on who owns the car, how it is used for business purposes, and whether private use is allowed. The Tax and Customs Board follows the principle that not only the actual use of the car matters, but also the possibility of private use. Therefore, the Transport Administration must be notified if an employer does not allow a company car to be used for private trips – otherwise the tax authority may treat the situation as providing the opportunity for private use.

There are several ways to handle car-related expenses in business operations, each with its own advantages and disadvantages. Below, we take a closer look at these options so businesses can compare and choose the most suitable solution.

1. Passenger car owned by the company

1.1 Business use only (so-called “100% business car”)

If an employer does not allow a company passenger car to be used for private trips, this must be reported to the Estonian Transport Administration. The notification obligation only applies to M1-category vehicles (passenger cars); there is no such obligation for N1-category vehicles (vans).

If the company car is used exclusively for business trips, the company should also ensure that:

employees are registered in the Employment Register (TÖR); and 
salaries are declared in appendices 1 and 2 of the TSD tax declaration. 
According to the tax authority’s guidance, business trips generally presume the existence of employees. However, this should not exclude companies where only a management board member is actively carrying out business activities.

Business trips may be tracked using automated systems or a logbook, which must show the connection between the trips and business activities (e.g. purpose of the trip, clients visited). A summary explanation may also be used if the trips are repetitive in nature (for example, a sales representative visiting the same stores every week according to a fixed schedule). Fuel purchases should also be consistent with the records. The tax authority is not naïve – simply filling in a logbook is not enough.

If the passenger car is used solely for business purposes:

• no fringe benefit arises and no related taxes are payable;
• input VAT may be deducted in full for the car and related expenses, including fuel, tyres, etc.;
• the company must be able to prove that no private use takes place. 

Example

A company’s sales manager uses the car only for client visits, and the car remains in the company parking lot after working hours. A trip logbook is maintained.

• This qualifies as a 100% business-use vehicle. No fringe benefit arises, and the company may fully recover input VAT on all related expenses.

Summary: key advantages and disadvantages of a 100% business-use vehicle

 

Advantages

• Maximum tax efficiency.
• Suitable for businesses where employees require highly flexible mobility.
• Clear tax treatment (if all requirements are met). 

Disadvantages

• Significant evidentiary burden.
• Difficult to manage in practice (generally, the car should not remain at the employee’s home overnight).
  • High tax risk if documentation is insufficient → retroactive fringe benefit taxation and correction of deducted input VAT. 

1.2 Car also used for private purposes (so-called “50% car”)

A fringe benefit arises when an employer allows a company car to be used for private trips, meaning the car is in mixed use. What matters is not the actual private use, but the mere possibility of private use – for example, leaving car keys on a secretary’s desk for anyone to take.

The tax treatment of the fringe benefit is not affected by whether the employee reimburses private trip costs. Therefore, if the employee has the opportunity to use the employer’s car for personal purposes, a fringe benefit exists regardless of whether the employee drives 5 or 555 kilometres privately.

Private trips cannot be reimbursed based on mileage records, meaning a logbook is not required for private use. However, if the employer wishes to prove that the car is used exclusively for business purposes, a logbook (e.g. GPS-based tracking) may be maintained. In addition, the company must register the vehicle as “business use only” with the Transport Administration. Without such registration, the vehicle is automatically considered available for private use and must be declared as a fringe benefit – even if no private trips actually occur.

If the car is used both for business and private purposes:

• input VAT deduction is limited to 50% of related expenses;
• a fringe benefit arises and is subject to income tax and social tax based on the vehicle’s power and age. 

Example 1

A management board member uses the company car for personal trips during weekends.

• Input VAT on related expenses may only be deducted at 50%, and fringe benefit taxes must be calculated and paid.

Example 2

An employee has access to a company car outside working hours but claims not to use it privately.

• The tax authority still treats this as mixed use → a fringe benefit arises, taxes apply, and only 50% of input VAT may be deducted.

How is the fringe benefit value calculated?

If an employer-owned or controlled passenger car is made available for non-business purposes, the monthly taxable fringe benefit value is:

• EUR 1.96 per kW for cars up to 5 years old;
• EUR 1.47 per kW for cars older than 5 years. 

The engine power (kW) can be found in the Estonian Transport Administration register or in the vehicle registration certificate.

For hybrid vehicles, the basis is the maximum power of the internal combustion engine.

For electric and gas-powered vehicles, the registered motor power is used.

The same kW-based calculation may also be applied to N1-category vehicles (vans) if private use is allowed.

Example

Vehicle power: 120 kW
Vehicle age: less than 5 years

• Fringe benefit value: 120 × EUR 1.96 = EUR 235.20
• Taxes:
  • income tax: 235.20 × 22 / 78 = EUR 66.34
  • social tax: (235.20 + 66.34) × 33% = EUR 99.51 

Summary: key advantages and disadvantages of mixed-use vehicles

 

Advantages

• Very easy to administer; no logbook required for separating private trips.
• Low dispute risk.
  • Safe model from both the Estonian Tax and Customs Board’s and taxpayer’s perspective.
• Flexible for employees.
  • Unlimited private use allowed. 

Disadvantages

• Ongoing tax cost.
  • Income tax and social tax payable every month.
• Input VAT deduction limited to 50%.
• Tax cost does not depend on actual private use. 

2. Use of a personal car for business purposes

Business tools do not always need to belong to the employer. Employees may use their personal vehicles for business purposes, and employers may compensate these costs within legal limits.

Compensation may be paid for the use of a car that is not owned or controlled by the employer. The car does not need to belong to the specific employee, but the right of use must be documented (e.g. vehicle registration certificate or power of attorney). Passenger cars include M1 and M1G category vehicles.

To pay compensation, the employer must issue a written decision containing:

• the recipient’s details;
• the amount of compensation; and
• the compensation period. 

A document proving the right of use must be attached.

Tax-free compensation may only be paid if business trips are documented in a mileage logbook. The logbook must contain information on trips, mileage, and purpose.

The company may reimburse:

• up to EUR 0.50/km;
• up to EUR 550 per month;
• provided that a mileage logbook is maintained.

The EUR 0.50/km is the maximum tax-free rate. Employers may choose a lower rate (e.g. EUR 0.30/km), but the monthly cap of EUR 550 still applies.

Example 1

An employee drives 800 km for business purposes in a month.

800 × EUR 0.50 = EUR 400

• The employer may reimburse the full EUR 400 tax-free.

Example 2

An employee drives 1,400 km for business purposes.

1,400 × EUR 0.50 = EUR 700

• Only EUR 550 may be reimbursed tax-free.
• The remaining EUR 150 is taxed as salary.

Example 3

An employee drives 350 km, but the employer reimburses EUR 1/km.

350 × EUR 1 = EUR 350

• Only EUR 175 is tax-free.
• The remaining EUR 175 is taxed as salary.

Summary: key advantages and disadvantages of personal car use

 

Advantages

• Tax-free within legal limits.
• No fringe benefit.
• No risks associated with company-owned assets.
• Suitable for occasional or temporary business use. 

Disadvantages

• Monthly reimbursement cap may not cover actual costs.
• Mileage logbook required.
• No input VAT recovery possible. 

3. Self-supply and fringe benefits

Cars are not the only transport vehicles used in business. Businesses may also use motorcycles, boats, aircraft, or helicopters. In these cases, private use may also trigger taxation.

This may involve:

• self-supply taxation under the VAT Act; and
• fringe benefit taxation subject to income tax and social tax.

Self-supply means the use or transfer of company assets free of charge for personal or non-business purposes, including by employees or management board members. It applies if input VAT has been deducted on acquisition.

Passenger car use for non-business purposes is generally not treated as self-supply, except in specific cases defined by law.

Example: motorcycle

Estonian tax laws do not contain special rules for private use of motorcycles, so businesses must determine an appropriate taxation method themselves.

Possible approaches:

• based on market rental price;
• based on the difference between market price and discounted price;
• by analogy with passenger car taxation, using engine power and age.

Motorcycle private use must be declared in appendix 4 of the TSD declaration under code 4050.

Unlike passenger cars, motorcycles are not subject to the general 50% input VAT restriction. If the business generates taxable turnover, input VAT on the motorcycle and related expenses may be deducted in full. However, private use is taxed as self-supply for VAT purposes.

The taxable value of self-supply includes VAT and is based on the fringe benefit value calculated under income tax rules.

For aircraft and boats, applying the passenger car analogy is often more difficult. Therefore, the company must be able to prove the financial value of the benefit granted to employees and correctly calculate monthly taxes.

Summary: key advantages and disadvantages of self-supply taxation

 

Advantages

• Flexibility in actual use.
• Allows adjustments if usage changes over time. 

Disadvantages

• Complex calculations.
• Passenger car analogy often cannot be applied.
• May create unexpected tax liabilities. 
• Frequently underestimated risk. 

Practical conclusion

• The 100% model is tax-efficient but risky if control and evidence are insufficient.
• The 50% model is simple and secure but creates ongoing tax costs.
• Using a personal car is practical for limited business use.

👉 Most companies consciously choose mixed use because it carries the lowest tax risk.
