Our tax office was the worst before they moved! Smallish downtown area with court house and all government offices together so there was never any parking (although since it was an old downtown the parking was along the streets which are still shaded by huge old trees, so that part was nice!) - but once you did find somewhere to park and got inside, it was chaos - small area to wait, had to be in a line, which had to wind out the door - three folks working the counter. Then when you got up there you learned they don’t take credit or debit cards - just cash or checks. Seriously.... who doesn’t take debit? But now they do - hard to believe government improved!
As long as banks impose a fee upon the merchant, they are unable to use these cards.
In our case there is no legal method to charge the taxpayer a fee to cover the swipe fee, and there is no will to force banks to waive the swipe fee for government transactions.
I can pay some bills online using a credit card if we use a third party to be the intermediate, and we agree to pay the ~ $3.95 convenience fee.
Our “progressive” local governments still collect taxes like it was 1955.
