Sixt Discount Codes in September 2026
Save with our selected list of working Sixt coupons today
Meet your expert
Hello, my name is Trent, and I've been adding coupons to our Sixt page since 2021. My hack for saving at Sixt is to book as soon as you know your travel arrangements. No matter what the time of year, you'll always get discounts, usually between 5 to 20% on your booking.
Book at the start of the week
If you have the chance, we suggest booking at the beginning of the week. You can save up to 40% at participating Sixt locations when you book any day between Sunday and Wednesday. They key is you have to return the car on Thursday of that same week. These are naturally for shorter stays, but can save you $100's. Here are some examples:
$40 per day for the BMW 3 Series (starting on Monday) instead of Wednesday, when the same car is $46 per day.
$10 off per day for the Chrysler Pacifica when you book for Monday September 14th, 2026 instead of September 16th, 2026
$75 per day instead of $94 for the same Volkswagen Jetta
Business travelers get up to 15% off
Long-term business rentals get 15% off or more, and the discount holds steady whether you rent for one week or one month. This covers travel managers, fleet managers, and business travelers booking through a company account. Here are some examples of how much you can save with the corporate customer discount:
Toyota Camry model for $40 per day, instead of the regular $45 rate
BMW X1 for $37 instead of the regular $50 rate - a 25% discount
$75 for the Chevrolet Tahoe, instead of $125 for non corporate customers, equal to $50 off per day

Frequently asked questions about Sixt
Check your hotel and airline partners first
Sixt partners with tens of brands to offer rental discounts you can't find on the main booking page. They have 43 total airline partners, 13 hotel partners, and four others. Some top examples include:
Get 750 Marriott Bonvoy reward points when you book any SIXT rental car.
Delta SkyMiles members earn two miles for every $1 spent at SIXT.
Up to 15% off Best Western Rewards when you book a SIXT rental car.
Student, teacher, and healthcare discounts
Any one of the following groups can save on their Sixt orders, every time they book:
Students: 10% off any rental with a valid student ID
Teachers and school employees: 15% off with a special code upon registration
Healthcare workers (doctors, nurses, medical staff): 15% off
The teacher code is reusable, so save it for future bookings instead of using it once and forgetting. Find these under "Car rental deals" then "Car Rental Coupons."
How to apply a coupon
We recommend using the free Sixt app when applying coupons, as it's a little more intuitive. Here are the steps:
1. Sign in or create an account.
2. Open "Account" in the main menu.
3. Tap "Vouchers & Benefits."
4. Enter your code under "Rent," "Share," or "Ride."
Join Sixt ONE if you rent more than twice a year
The Sixt ONE loyalty program is free and starts you at express member status before your first booking. Top tier perks include:
Up to 20% off regular rates
30% more rental points
Skip-the-counter service
We suggest this program for anyone who uses Sixt at least two to three times per year. If it's only something you may use once on your summer vacation, then you don't have to be a rewards member.
