Even as the politicized tax enforcement scandal expands, the Internal Revenue Service continues to expand its political powers thanks to the Affordable Care Act. A larger government always creates more openings for abuse, as Americans will learn when the IRS starts auditing their health care in addition to their 1040 next year.

Over the last decade or so the tax agency has stretched its portfolio and become an enforcer and decision-maker for government benefits and programs. Three years ago, National Taxpayer Advocate Nina Olson, who operates within the IRS, presciently noted that ObamaCare is "the most extensive social benefit program the IRS has been asked to implement in recent history."

This March the IRS Inspector General reiterated that ObamaCare's 47 major changes to the revenue code "represent the largest set of tax law changes the IRS has had to implement in more than 20 years." Thus the IRS is playing Thelma to the Health and Human Service Department's Louise. The tax agency has requested funding for 1,954 full-time equivalent employees for its Affordable Care Act office in 2014.

Instead of going after tax cheats, these bureaucrats will write and enforce tax regulations for parts of the economy in which they have no core competence. For example, do ski instructors or public school teachers count as seasonal workers? How long is a "full time" work week? Is it 40 hours, or 30?

The IRS will also dispense ObamaCare's insurance subsidies since technically they're "advanceable" tax credits, i.e., transfer payments made prior to filing a tax return. The IRS will also police the individual mandate-tax to buy health insurance, as well as the business penalties for not offering Washington-approved coverage to employees.
