so I know that a refundable tax credit is rare, and an advanceable refundable tax credit is even rarer.
EIC is one that any low income individual will know, and there is a way to get an advance with a simply form filed through your employer.
Cash for clunkers operated much like a refundable tax credit. Car dealers that participated complained about the massive paper work, claims denied, and delayed payments.
And this was a temporary program that lasted 5 weeks.
I fail to see how a much more massive program (subsidies) will work any smoother and with less hassle.
