Yahoo! News - Report: U.S. to save $1B with gay marriage
Allowing same-sex couples to marry would have a positive impact on the U.S. federal budget to the tune of an additional $400 million per year until the end of this decade, the Congressional Budget Office announced Monday.

Such an allowance would boost federal income tax revenues mainly due to the alleviation of the so-called "marriage penalty" income tax -- a glitch in the tax code that prior to last year's tax-cut legislation, imposed a penalty on newlyweds. Receipts from other taxes, particularly payroll taxes, would be unlikely to change significantly.

Social security payments would also rise over time, as would spending on spousal health insurance benefits for federal workers, if gay couples were allowed to legally marry, the report affirms. However, spending on Medicaid and Supplemental Security Income would fall, CBO Director Douglas Holtz-Eakin wrote in a letter to Rep. Steve Chabot, R-Ohio, who requested the analysis.

The net impact would be a federal budget savings of nearly $1 billion per year, assuming that same-sex marriages are legalized in all 50 states and recognized by the federal government, he reported.

This must be why the "conservatives" are so against it- it would make good fiscal sense. God knows they can't have that.
