Sharing a lease car with a colleague: these are the rules.

The average lease car stands idle 90% of the time, while colleagues without a car take a hire car or claim mileage. No wonder more and more organisations are thinking about sharing lease cars. But is that simply allowed? And what about the taxable benefit, the insurance and the Dutch Tax Administration? The key questions, and the answers.

Can I simply share my lease car with a colleague?

Not just like that, but it is allowed. Your employer has made the lease car available to you. That means the employer decides whether sharing is allowed and under what conditions: the sharing policy. In addition, three hard rules apply:

• Only within the same tax entity. Sharing is possible with colleagues who fall under the same Chamber of Commerce number. That keeps the making available clean for tax.
• The insurance must allow it. The policy conditions must be checked in advance for multiple drivers.
• Use must be recorded. Who drove when, business or private? Without those records, sharing cannot be justified for tax.

And renting out to people outside the company, for example via public sharing platforms? The lease contract usually does not allow that, and it falls outside the tax scope of this article.

Does the taxable benefit shift if a colleague drives privately?

Yes, this is called benefit shifting. For the days a colleague uses your car privately, the taxable benefit falls to that colleague. You then only pay the taxable benefit for your own private use. The attribution follows the making available per calendar day and per registration number, is in line with existing legislation and regulations and has been confirmed in case law, including rulings of the Dutch Supreme Court. Policy also explicitly supports shared use of the company car.

There is one big but: it only works if private use per person is recorded to the day and correctly processed in payroll, including the personal contribution, VAT and an auditable audit trail. A spreadsheet and good intentions are not enough for the Dutch Tax Administration.

A colleague's business trip, by the way, does not shift any taxable benefit. So that is always possible, with no tax consequences for the regular driver.

Can a pool car also be used privately?

For tax, this is a very delicate matter. As soon as a pool car is also available privately, the taxable benefit and (from 2027 for fossil-fuel cars) the pseudo final levy can come into play. Without a watertight trip log, the employer also runs the risk that the Dutch Tax Administration assumes private use, resulting in an additional assessment.

Within the Klicq platform, pool cars are therefore only available for business trips: the borrower confirms this with every booking, and every trip is recorded per driver. If an employee wants to drive privately, that is possible with a colleague's shared lease car. That is exactly where benefit shifting is neatly arranged.

Can I swap cars with a colleague?

Yes. Two lease drivers who both drive a lease car with a taxable benefit can swap cars for an agreed period: the estate car for the holiday, the compact city car for the weekly market. The taxable benefit shifts automatically to the car each of them drives during that period. With a swap there is no mileage limit and no per-kilometre settlement.

Note the distinction: a lease driver swaps with another lease driver, and lends their car to colleagues without a lease car. So a lease driver never rents a second car themselves. For swapping too: the employer must allow it and the swap must be correctly recorded and processed.

What about insurance, damage, fuel and fines?

• Insurance: have the policy conditions checked in advance for multiple drivers. This is a task for the employer or fleet manager.
• Damage: because every trip is linked to a driver, it is always clear who drove when. Damage is reported and handled without the regular driver being held responsible.
• Fuel and charging: go through the car's fuel or charging card. What the borrower pays for this depends on the sharing policy: unlimited driving, free allowance plus excess rate, or an all-in price per kilometre.
• Fines: thanks to the records, they can be traced to the driver at that moment.
• Rules: clean, charged or refuelled and back on time. Anyone who does not stick to them temporarily loses the right to book.

What does the employer need to arrange?

Sharing starts with a clear sharing policy: what does the borrower pay, how many free kilometres does the employer give away, if any, and may cars be shared for business only or also privately? Tax-sensitive settings belong to a consistent course of conduct and are adjusted at most once a year. In addition, an agreement on a personal contribution for private use is needed for each participating employee, the employer must inform the Dutch Tax Administration itself that sharing takes place, and a statutory seven-year retention obligation for tax applies to the records.

Conclusion: sharing is allowed, but it only really works with a watertight system

So the rules are easy to grasp: the employer's permission, within the same Chamber of Commerce number, insurance in order and, the common thread, watertight records and correct tax processing of every shared trip. That last point is exactly where manual solutions fail: spreadsheets, emails and expense forms are error-prone, take time and provide no audit trail the Dutch Tax Administration can work with.

That is what Klicq was built for. The platform arranges the whole chain automatically: availability and booking in the app, day-accurate records per trip and driver, benefit shifting and personal contribution correctly in payroll, and an unalterable seven-year audit trail. That makes sharing lease cars not only effortless in practice, but also watertight for tax.
