What the Colorado letter has to contain
- Every deduction on its own line. Colorado requires an itemized statement rather than a lump sum (Colo. Rev. Stat. § 38-12-103).
- 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 Colorado 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 Colorado 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.
