Tonight, due date for estimated payments, “payUSAtax” rejected an Ink Cash card twice and then accepted an AmEx Delta Biz. I called Chase to confirm the card was good to go. “Pay1040” also rejected the Ink Cash. “ACI Payments, Inc.” accepted the Ink Cash. No pattern or rhyme or reason.

(I sweated this one a bit, it was 8-9-10pm and I’m leaving at 9am for a 5 days quasi MR/MR (mileage run/mattress run) and one of the cards is 2 months old and these changes to meet minimum spend are the only charges planned for both cards. Also did NYS estimated taxes with 2 other cards. Quite pleased that it all worked out.)
