I was wondering about how counting those refundable credits as negative taxes would change the comparison of revenues under the Obama plan with current policy extended--whether it would still be a net tax increase compared with that policy-extended baseline or not. Seems that you're saying it's worth $648 billion (over ten years), so that's still falls short of offsetting the net revenue increase (of +$778 billion) relative to the policy-extended baseline. I thought Austan said you need to count the health care subsidies, too, in order to get to the "net tax cut" position, so maybe that explains how the Obama plan has to be counted to come up with the "net tax cut" relative to policy extended story. Will TPC be estimating the cost and distribution of those health subsidies?
