Grace period, late fee cap, and pay-or-quit notice rules
Montana does not provide a statutory grace period. Rent is due on the date specified in the lease, and a landlord may technically charge a late fee and serve a pay-or-quit notice immediately after nonpayment — though many leases include a contractual grace period. Always check your lease agreement before acting.
No grace period. Late fee limited to $25 per notice after 3-day notice is given; 3-day notice required.
Montana caps late fees at $25 per notice under Mont. Code Ann. § 70-24-422. Any late fee above this statutory maximum is unenforceable, even if the tenant agreed to it in the lease. At the statewide median rent of $884/month, a 5% fee would equal approximately $44 — verify the exact percentage allowed under your state's statute.
Once rent is late and no grace period applies, the landlord must serve a formal 3-day pay-or-quit notice (Mont. Code § 70-24-422) before filing for eviction. This notice must state the total amount owed and give the tenant the option to either pay in full or vacate. If the tenant does neither, the landlord may file an unlawful detainer action in Montana court.

Technically yes — one missed rent payment is grounds for eviction in Montana. However, landlords must first serve a 3-day pay-or-quit notice and wait for it to expire before filing. Most landlords prefer to work with tenants before filing, as eviction court costs and lost vacancy time often exceed one month's rent.
