AI Bookkeeper's salestax return --state XX builds a return worksheet and dates it from a table of state due days. Audited today, five states were missing from that table: Oregon, Montana, New Hampshire, Delaware and Alaska. The reason is that they levy no general state sales tax, but the command said nothing, so a user typing --state OR got a worksheet with default dates and no hint that Oregon has no such return.
Each of the five now adds a warning. Delaware's tax is a gross receipts tax on a different base, Alaska's are local with their own forms, New Hampshire taxes meals and rooms separately, and Montana has local resort taxes.
Caveat: the wording is from memory of each state's published position, not read from the state sites this run (several are blocked from the sandbox), and the README says so. One test pins the five notes and that Texas stays silent.
