Perhaps that belief was partly due to my post #12, where I reported that PayUSATax rejected my JCB card number, and post #26 where trumpet205 reported that a Discover representative had claimed that the JCB/Discover agreement to share their authorization network is for "card present" transactions only.
However, I just updated my post #12 in this thread to report that Official Payments accepted my JCB Marukai card for an online payment of California estimated income tax. I selected "Discover Network" as the card type.
