I posted the following on an old thread called "Paying IRS with Bluebird" over on the credit card forum. But I received no replies, so perhaps it is better asked here. (I deleted it over there.) Now that Bluebird checks have arrived and many of us have them in hand, I may not be the only person with small enough tax payments due to enable paying the taxes with Bluebird. I just need a little reassurance. I have only used BB once, to send a mortgage payment, and that was before I received my checks in the mail. It worked fine. Now I want to pay a federal tax bill of under $2000, a state bill of a few hundred, and an estimated federal payment of $300. I have the BB checks in hand and enough money in the account, so can I just go onto the site, pre-authorize the three checks immediately since they are under $2000 each, write the authorization numbers on the checks along with the other details, and mail them on their way? Sounds almost too good to be true. Have you done this or do you plan to? Thanks.
