Wis. Stat. § 704.28 — the deadline to return the deposit and send the itemized statement

What the Wisconsin letter has to contain

  • Every deduction on its own line. Wisconsin requires an itemized statement rather than a lump sum (Wis. Stat. § 704.28).
  • 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 Wisconsin 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 Wisconsin deduction page, which prorates each item by its remaining useful life.
