A file-directly-with-IRS program was piloted by the Biden administration, available in a subset of states to begin with; it got a couple hundred thousand users the first year and something like 350k users the second year if I remember right. The next administration killed it.
Ditto; Since the first Trump administration - it isn't worth my time to itemize. I backdated 3-years of returns and they all came out to less than $75 - $100 in tax savings - Not worth the additional time, effort, and possible mistakes or audit review. I'm always in the middle or slightly to the right of center on the programs' audit risk gauge - So I guess I have a lot of outliers - but I've got receipts for each and every one of them.
