Do you have a company car and pay tax on the full benefit value? With a correct digital driving log you can deduct business travel and save thousands of euros a year in tax. Here we explain exactly how it works and what you need to consider.
When you have a company car, you are taxed for the car benefit - the Swedish Tax Agency calculates a standardised value based on the price of the car. But if you drive for work, you can reduce the taxed preferential value by deducting business travel expenses.
Without a driving licence? Then you'll be taxed on the full value of the benefit, even if you drive the 80% on business. That's money straight out the window.
The benefit value is calculated according to the standardised rules of the Swedish Tax Agency:
| Component | Calculation |
|---|---|
| Basic amount | 29% of the new price (up to 7.5 price base amounts) |
| Over 7.5 price base amounts | 20% of the excess amount |
| Additional equipment | Added to the new price |
| Vehicle tax | Added to the preferential value |
| Fuel benefit | Additional if employer pays for fuel |
A Volvo XC60 with a new price of SEK 550 000:
With a mileage log showing that 60% of the driving is business travel, you can reduce the benefit value by ~44 900 kr - it is ~SEK 22 450 less in taxes per year.

Does NOT count as business travel:
Med Boomr Fleet you get a small GPS puck that plugs into your car's OBD port. It automatically logs every journey - you don't have to do anything.
In the app or dashboard, mark which trips are business and which are private. Tip: do it weekly and it only takes a few minutes.
At the end of the year (or at tax time), you export a Skatteverket-approved report which shows exactly what proportion was business travel.
Your employer will adjust the value of the benefit based on the mileage rate. Alternatively, you can make the deduction yourself in your tax return.
