Filing & paying

Correct me if I'm wrong, but it is my understanding that you must pay when you file. The payment and filing papers must be in the same envelope. I wouldn't blame the last-minute taxpayers at all. Intuit says they can handle the load, so if they can't, the fault is clearly on them. Having said that, I filed my taxes in March. The way I see it, the only reason to wait until the last minute (especially if you're doing the taxes yourself, either by paper, phone, or software) is if you don't have the money. The people who wait until the last minute to pay because they want that extra bank interest on the money they'll be paying are just asking for trouble.
