They asked for feedback after I canceled the login, I gave very candid feedback in a form.
Then they asked if I would give an interview.
You know why I wanted to log in? To claim a $7 refund.
They ended up mailing it.
I also make sure they never owe me. Otherwise I get delayed money, ID thieves have another reason to target me, thieves might actually get it, and the IRS might not give it. And the last thing happened to me once with a large refund, for a year, because of a pure logistics error on their end that took me a ton of effort to get them to fix, and it was kinda related to ID. Identity situation is much cleaner if I just pay the IRS.
(this is from the Netherlands where you can use digID [0] to sign into government services and ID-bound 3rd parties like insurance, mortgages, pensions etc)
