Company car policy and benefits 2026 – tax, mileage log, and return

A company car policy should connect tax regulations with the company's practical rules regarding the choice of car, private use, fuel, mileage logs, damages, and return. When an employee is allowed to use an employer's car for private purposes more than to a negligible extent, a taxable car benefit normally arises.

When does a car benefit arise?

The Swedish Tax Agency states that a car benefit is normally taxable when the employee is allowed to use the employer's car for private purposes on more than 10 occasions or for more than 100 kilometers per year. Both limits must be met for private use to be considered negligible. Travel between home and the workplace is normally considered private travel.

Mileage log as evidence and control tool

A precise mileage log is the most important practical documentation to show how the car has been used. It should include, among other things, the date, odometer reading, start and end address, distance, and the purpose of the business trip. The car policy should specify who is responsible for the log and how often it should be submitted.

Fuel, charging, and congestion tax

If the employer pays for fuel for private trips, a fuel benefit normally arises. Congestion tax and infrastructure charges for private trips can also be taxable benefits. From July 1, 2026, charging at the workplace is permanently tax-exempt under the conditions specified by the Swedish Tax Agency.

30,000 kilometers of business driving and reduced benefit value

With at least 30,000 kilometers of business driving during the calendar year, the employer can reduce the car benefit value to 75 percent of the full value. Therefore, the policy should require sufficient documentation throughout the year, not just retroactively.

Return and damages

The policy and the individual company car agreement should regulate normal wear and tear, damages, insurance excesses, service, tires, keys, and what happens when the employment or car benefit ends. A documented return inspection reduces the risk of disputes.

Common mistakes to avoid

• Only having verbal rules regarding private use.
• No mileage log despite the tax assessment being dependent on usage.
• Confusing car benefit with fuel benefit.
• Missing rules for damages, insurance excess, and abnormal wear and tear.
• The policy is not updated when tax regulations change.
