Car rental deposit: what it covers and how to return it
Last checked 5 October 2026
The deposit is where most arguments with renters start. A customer who gets their deposit back quickly, with every deduction explained, books again. One who waits a week with no answer leaves a bad review.
What the deposit covers
It is not part of the rental price. Whatever is not used goes back to the renter.
- Fuel below the pickup level.
- Mileage above the limit in the agreement.
- Late return charges.
- Summons, tolls and parking during the rental.
- Cleaning, and small damage below the insurance excess.
Setting the amount
Set one amount for each type of car and use it for every customer, so nobody feels singled out. A bigger or more expensive car needs a bigger deposit. Think about what you would actually deduct after a bad rental: a tank of fuel, a few hundred extra km, a summons. Write the amount in the agreement.
At pickup
- Record the mileage and fuel level, and take photos of every side of the car.
- Give the renter a receipt for the deposit.
- Tell them when and how it comes back, and that the agreement says so.
At return
- Compare the mileage, fuel and photos with the pickup records.
- If you deduct anything, list each item with its amount and send it to the renter.
- Pay back the balance to the account they paid from, and record the date.
Summons that arrive later
Summons and compounds can reach you weeks after the car is back. Your agreement should say the renter pays for any offence dated within the rental, even if it arrives later. That way you can return the deposit quickly and still claim a late summons, instead of holding everyone's money for weeks.
Keeping track
With many cars out, it is easy to forget whose deposit has not gone back. In SmartDrive you set the deposit for each car model, record mileage and fuel at pickup and return, and the Mileage page lists every returned car whose deposit is not marked refunded, with the ones past 48 hours in red.
