Not at the same time, but soon. Today, you can split one of them through Split Pay — but not both concurrently.
How to think about which one to choose:
Pick the one where splitting helps you most. Usually that's the larger payment, or the one whose due date lines up worst with your paycheck.
Pick the one with less flexibility on its own. Some lenders and landlords are more flexible than others when you need a few extra days — pick the bill where splitting saves you the most friction.
Common patterns:
Rent is usually the bigger bill → split rent, pay your car loan in full from cash
Rent date is tight with your paycheck → split rent for breathing room, pay the car loan on its own schedule
Car loan has stricter late fee policies than your landlord → consider splitting the car loan instead
You can switch between them. If you split rent this month and want to split the car loan next month, that's possible once your current Split Pay is fully paid off. See the FAQ on Can I switch which bill I use Split Pay for?.
Looking ahead: multiple concurrent splits are on our roadmap. When that launches, you'll be able to split rent and your car loan at the same time. No firm date yet — we'll let you know when it's live.
