"Tax Subsidies"

There are different ways in which a government subsidizes.  There are direct hand-outs (grants), and indirect hand-outs (subsidized loans, loan guarantees).  

And then there are tax deductions and credits: 

Federal tax receipts are reduced by more than $1 trillion a year by various tax deductions and credits, known as tax expenditures, often tied to a policy aim. Ending them would nearly eliminate the federal deficit, which is projected to be $1.2 trillion in the current fiscal year.

But the three largest are as popular as they are expensive: the mortgage interest deduction has cost about $75 billion a year recently, the employer deduction for health care has cost $120 billion a year, and the charitable-giving deduction has cost $38 billion a year, according to the bipartisan Joint Committee on Taxation.

Still other tax breaks verge on the unpopular, criticized by aides of both parties. Offshore tax havens and other tax shelters cost the government about $150 billion a year, said Senator Kent Conrad of North Dakota, chairman of the Senate Budget Committee.
