Tricky promotion making it a Jan 15 deadline: for one, a lot of people don't even have the required data to file by then. (I seem to get all of my 1099's in early Feb.) Two, anybody who pays their 4/15 balance due in January is being too nice to The Man.

Yes, I do pay quarterly taxes. I would agree with you-I wouldn't pay three months early to get the miles. As it is, by paying with the credit card not only do I get the miles but I get a deferral until late February to come up with the cash. But I still wouldn't do it except for double miles and for a regular quarterly tax payment.
