Montana Late Rent Fee Rules: Limit, Grace Period and Notice
Montana sets no statutory cap on late rent fees — the lease controls, and the fee must be reasonable. Set the rule once on the lease and the fee posts itself the day it is allowed.

What applies to your Montana lease?
The cap, the grace period and the wording all matter. The rule on each card is Montana's statutory position — your lease can be more lenient, never harsher.

What a Montana late fee clause must say
✓
The amount, within the Montana limitNo statutory cap in Montana, but the fee must be a reasonable estimate of your cost — 5% of rent is the customary ceiling courts accept.MCA § 70-24-441
✓
The grace periodNone required by Montana statute; state the one you give (3–5 days is customary) so the tenant knows the date.
✓
When it is assessedThe day after the grace period ends, once, for that rent period.
✓
How it is chargedAdded to the ledger as a separate line, never folded into rent — it stays visible and cannot be disputed as a rent increase.
✓
No fee on feesA late fee never accrues interest or a second fee; returned-payment charges are separate and must also be in the lease.
✓
Same rule for every tenantApply the lease rule uniformly; waiving it for one tenant and not another invites a fair-housing complaint.auto-applied
How it works
1 · Set the rule on the leaseLease → late fee: amount or percentage, and the grace period. The Montana limit above is the ceiling.
2 · Rent goes lateThe day after the grace period the fee posts to the tenant's ledger as its own line, with the date.
3 · Collect or waiveThe tenant pays it with rent (autopay picks it up); you can waive any fee from the ledger and it is logged.
Montana late fee FAQ
How much can a Montana landlord charge for late rent?
No statutory cap (MCA § 70-24-441).
Is there a grace period in Montana?
None set by statute — the lease controls.
Can I charge a daily late fee?
Daily fees are struck or capped in most states because they read as a penalty rather than a cost; one fee per rent period, stated in the lease, is the enforceable form.
Does the late fee count toward an eviction notice?
The pay-or-quit notice can include late fees the lease allows; the in-app notice lists rent and fees as separate lines with the total.
What if the lease says nothing about late fees?
Then you cannot charge one. Add the clause at renewal — a mid-term notice does not create the right.
