Tax expenditure

Tax expenditures include credits (such as the child tax credit) and deductions (such as home mortgage deduction) and the new Obamacare tax credit that are targeted only to those tax filers who are eligible and not to everyone, and when used by tax filers, reduce federal revenues that would otherwise have been collected.

The policy is widely accepted that tax expenditures are a form of spending and analogous to discretionary spending or mandatory spending for those who meet statutory criteria.

Every year, the U.S. Treasury publishes a tax expenditure budget as required by law. The net effect on the Treasury is the same. There is also case law that tax deductions, exclusions and credits are treated as expenditures.
