This Martin Feldstein op-ed on Obama’s charitable giving plans is pretty blunt:
President Obama’s proposal to limit the tax deductibility of charitable contributions would effectively transfer more than $7 billion a year from the nation’s charitable institutions to the federal government. But the high-income taxpayers affected by the rule change are likely to cut their charitable giving by as much as the increase in their tax bills, which would, ironically, leave their remaining income and personal consumption unchanged.
In effect, the change would be a tax on the charities, reducing their receipts by a dollar for every dollar of extra revenue the government collects. It is hard to imagine a rationale for taxing schools, hospitals, medical research budgets and arts organizations in this way. I suspect that the administration officials who drafted this proposal did not understand that it would have this perverse effect.
