Where and when you can return a Sixt rental
You can return a Sixt rental car at any Sixt location worldwide, not just the one where you picked it up. Most airport locations and city branches stay open until at least 10 p.m., but hours vary by location. The rental agreement you signed at pickup shows your specific return location and important date — check that document now if you're unsure, because returning to the wrong place or after hours can trigger extra charges.
If you booked a one-way rental (picking up in one city and returning in another), your return location is fixed in your contract. Returning elsewhere requires calling Sixt directly before you return the car; they may charge a relocation fee or refuse the return entirely. For standard same-location returns, you have flexibility within your rental period, but going over by even one hour usually costs a full extra day.
Sixt also offers drop-off at certain partner locations — gas stations, parking facilities, or hotels in some cities — but this is not available everywhere. Check your confirmation email or the Sixt app to see whether your return location offers after-hours drop-off. If it does, you'll receive instructions for leaving the keys and locking the car.
Key Takeaways
- Return your car to the location and by the time shown in your rental agreement, because returning late or to the wrong place triggers extra charges.
- Fuel the car to the level it was at pickup (usually full), or Sixt will charge you their fuel price plus a service fee.
- Walk around the car with the Sixt agent and photograph or video any damage before you leave, because damage found after you depart becomes your responsibility.
- Keep your rental agreement and return receipt until your credit card statement arrives, so you can dispute any unexpected charges.
- One-way rentals have a fixed return location; changing it requires calling Sixt in advance and may cost extra.
Fuel requirements and what happens if you return it empty
Sixt expects you to return the car at the same fuel level it was at pickup — almost always a full tank. If you don't, Sixt charges you for the fuel they add, plus a service fee that ranges from $5 to $15 depending on location. The fuel price they charge is typically higher than what you'd pay at a pump, sometimes 20 to 30 percent above market rate.
The easiest way to avoid this is to fill the tank yourself at a gas station near the return location before you drive to Sixt. Keep your receipt. When you return the car, the agent will check the fuel gauge in front of you. If it's full, they'll note it on your paperwork and you're done. If it's not, they'll calculate what you owe based on their internal pricing, which you won't see until your final bill arrives.
Some Sixt locations offer a "fuel service" option at pickup, where you prepay for a full tank and can return the car empty. This locks in a price upfront and removes the guesswork, but it's usually more expensive than filling up yourself. Read your confirmation email to see whether this option was included in your reservation.
Damage inspection and what to document before you leave
Before you hand over the keys, walk around the car with the Sixt agent and look at the damage report together. This is the moment to point out any scratches, dents, or interior damage you see — or to confirm that the car is in the condition you received it. The agent will note everything on a form or tablet. Take a photo or video of the form with your phone so you have a record of what was documented.
If you notice damage during your rental that you didn't cause, report it to Sixt when ready by phone or through the app. Do not wait until return. Damage reported after you leave the car becomes your financial responsibility, even if you didn't cause it. Sixt uses security cameras and photos taken at return to determine fault, and they will charge your credit card if they believe you're liable.
Minor damage like a small scratch or a dent smaller than a coin is often waived or covered by your rental agreement's damage waiver (if you purchased one). Major damage — broken windows, significant dents, undercarriage damage — will be charged to you. The cost depends on the car type and the damage severity. Sixt will send you an invoice within one to three weeks of return.
How to return the car early or extend your rental
If you want to return the car before your rental period ends, you can do so at any time without penalty. straightforward drive to a Sixt location, complete the return process, and you'll be charged only for the days you actually used the car. The agent will adjust your bill on the spot and provide an updated receipt.
If you need to keep the car longer, contact Sixt as soon as possible — ideally before your return time. You can call the location directly, use the Sixt app, or call the main customer service line. Extending is usually possible if the car hasn't been reserved by another customer, but availability varies. If you return the car late without extending, you'll be charged for the additional days at the daily rate in your original agreement, or at a higher rate if the car was booked by someone else.
Extensions are cheaper and simpler to arrange before you're late. Returning a car even 30 minutes past your important date without prior approval can cost a full extra day's rental.
What happens after you return the car
After you hand over the keys and sign the return paperwork, Sixt will inspect the car more thoroughly — checking for damage you may not have noticed and verifying the fuel level and mileage. This inspection usually takes place within 24 hours of return. If they find damage or other issues, they'll contact you by email or phone within one to three weeks.
Your final bill will be charged to the credit card you provided at pickup. This includes the base rental cost, any fuel charges, damage charges, tolls, parking violations, or late fees. Review your receipt from return day against your credit card statement when it arrives. If you see a charge you don't recognize or believe is wrong, contact Sixt customer service with your rental agreement number and photos or documentation of the car's condition at return.
Sixt typically holds a temporary authorization on your card at pickup (to cover potential damage), then releases it once the rental is complete and no charges explore. If damage charges are assessed, that authorization converts to an actual charge. This process can take up to 30 days, so don't be alarmed if your card shows a hold for longer than your rental period.
Returning a Sixt rental with damage or mechanical problems
If the car breaks down or develops a mechanical problem during your rental, call Sixt roadside information when ready. Do not attempt to drive it if it's unsafe. Sixt will arrange a tow or replacement vehicle at no cost to you. Keep documentation of the breakdown — the time you called, what the problem was, and what Sixt did to resolve it — because this protects you from being charged for damage you didn't cause.
If you return the car with a mechanical problem that developed during your rental (a warning light, a strange noise, a fluid leak), tell the agent at return and make sure they note it on the damage report. Do not sign off on the return until this is documented. Sixt is responsible for mechanical failures that occur during normal use, but only if they're reported before you leave.
If you caused the damage — for example, you hit a pothole and damaged the suspension — this is your responsibility. Damage waivers (if you purchased one) typically cover collision and theft but not mechanical failure caused by your actions. Review your rental agreement to understand what your waiver covers.
Returning a Sixt rental at an airport or after hours
Airport returns work the same way as city returns, but the location may be in a separate rental facility away from the terminal. Your confirmation email will tell you exactly where to go. Allow extra time to find the location and complete the return process, especially if you're unfamiliar with the airport.
If you're returning after the location's normal hours, check whether after-hours drop-off is available. Some Sixt locations have a designated drop-off area where you can leave the car, lock it, and drop the keys in a find box. You'll receive a confirmation number or receipt. If after-hours drop-off is not available and you return late, you'll be charged for the extra time.
After-hours returns are riskier because the car won't be inspected when ready. Damage found the next day may be harder to dispute if you're not there to document the car's condition. If you must return after hours, take photos or video of the car's exterior and interior before you leave it, and keep those files. Email them to Sixt customer service along with your return confirmation number.
Frequently Asked Questions
What if I return the car to the wrong Sixt location?
Call Sixt when ready. If the location you returned to can accept the car, you may be charged a relocation fee (typically $50 to $150) to move it to your original return location. If the location cannot accept it, Sixt will arrange to pick it up, and you'll be charged for that service. Always confirm your return location before you drive to Sixt.
Can I return a Sixt rental without the original driver present?
No. The person who signed the rental agreement must be present at return to sign off on the final paperwork and damage inspection. If someone else returns the car, Sixt may refuse to accept it or may charge additional fees. If you cannot return the car yourself, contact Sixt in advance to arrange an exception.
How long does it take to get my damage charges if Sixt finds something wrong?
Sixt typically sends damage invoices within one to three weeks of return. The charge will appear on your credit card statement 24 to 48 hours after you receive the invoice. If you disagree with the charge, contact Sixt with photos of the car at return and your damage report from that day.
What if I lose the rental agreement or return receipt?
You can request a copy from Sixt customer service using your rental agreement number (shown in your confirmation email) and the phone number or email you provided at booking. Keep this information handy. Without documentation, it's harder to dispute unexpected charges, so retrieve copies as soon as you notice a problem on your credit card statement.
Do I have to return the car with a full tank if I bought the fuel service option?
No. If you prepaid for fuel at pickup, you can return the car with any amount of fuel in the tank. The fuel service option means you've already paid for a full tank, so Sixt won't charge you extra. Check your confirmation email to confirm whether this option was included in your reservation.
