I don't think so, BigSis. It would not be a lift to the economy if it had to be directly recouped in any reasonable time. Congress passed it right quickly after Bush proposed it, and then it was a done deal. Had they gone back and made a simple $150 billion change so they could get the money back directly, someone would have noticed, I'm sure.
If you read back through the thread you will see that Jerome was adamant about his opinion, after being quoted to from the legislation by myself and others, and indeed, after quoting it himself. It plainly says what it says: the amount is a credit, which in IRS/accountant speak is the negative expression of a direct tax amount. There are other credits you can claim which directly mitigate taxes at that 100% level. Those amounts which mitigate against your tax liability (income), on the other hand, are called tax deductions, and all these terms have specific meanings in the legislation and tax law.
I probably wouldn't have even bothered to come back to this if Jerome hadn't been so bull-headedly stubborn in his beliefs. He didn't say he'd look into it and get back; he didn't say he was damned sure, but would check (which I myself most certainly did); no - he was right and the gates of hell would not withstand his word. He spoke of it as if it were a federal conspiracy theory, that they are tricking us with it just like they did in 2001 (which also is not true; GHBush was forthright in telling everyone exactly what he was doing, as I remember it, and I'm not an elder or junior Bush fan). If Jerome sends the money back to the treasury, I will then admire his stubbornness; but in any case, he is wrong.
