Mont. Code Ann. § 70-25-202 — the deadline to return the deposit and send the itemized statement
Montana provides for the deposit’s return within 30 days (10 days if there are no deductions) (Mont. Code Ann. § 70-25-202). At its shortest, 10 days, Montana gives landlords the least time of the 26 states verified here — miss it and the right to withhold is usually lost.

What the Montana letter has to contain
- Every deduction on its own line. Montana requires an itemized statement rather than a lump sum (Mont. Code Ann. § 70-25-202).
- The arithmetic, shown. Deposit held, each deduction, and the balance refunded or still owed — so nothing has to be taken on trust.
- Where the refund went. The forwarding address you sent it to, and how.
Proving you sent it in time
The deadline is about when the letter left, and in a dispute that is the fact in question. Email gives you a timestamp for nothing; certified mail gives you a receipt. Either beats posting it second class and hoping. Whatever you use, keep the copy you sent — a Montana deadline you met but cannot evidence is not much better than one you missed.
Working out what you can defensibly deduct is a separate job from writing the letter — that lives on the Montana deduction page, which prorates each item by its remaining useful life.

- Is the letter generator free?
- Yes — free, no signup. It itemizes deductions, does the refund math, cites the state deadline, and can email the PDF so the timestamp documents timely delivery.
