Yes — you can take a month off Split Pay. How depends on how you pay:
If you pay through a portal, lender, or servicer: change your payment method inside your portal for that month (back to your regular bank account or card). That's it — nothing to do on the Split Pay side. When you want to split again, add your Split Pay account and routing numbers back as the payment method.
If you pay your landlord directly: cancel your plan in the app, then set it up again when you're ready.
One thing to keep in mind — the eligibility clock:
If you've never used Split Pay, your approval lasts 30 days unused.
If you've used Split Pay and paid back your second payment, you get 60 days before eligibility lapses.
If your eligibility expires during your break, you can apply again — but a new application is a fresh review of your finances. So if you're planning a short break, it pays to come back inside your window.
