I wonder if all of the new home buyer tax credits will be automatically applied this way. This credit is not a taxable loan, like the old 7500 one, but an actual credit, to be refunded back to the buyer. If it is, I won't be a happy camper.
But, overall, it is just another reason why I try to break even every year. I have friends that use the refund as a "savings account." I would rather have access to my money over the course of the year, and invest as I see fit rather than let the gubmint make money off what I earn.
