The Internal Revenue Service is about to get slapped with a harsh payback for messing around with conservative groups, blowing wads of tax dollars on employee conferences and helping implement Obamacare.

The House Appropriations Committee is set to OK an IRS budget of $10.9 billion, $1.5 billion under President Obama's request for fiscal year 2015, reducing the agency's budget to 2008 levels.

The goal is to keep the tax agency focused on its "core duties," and eliminate efforts to judge the political activities of tax-exempt groups and brake its implementation of Obamacare.

The funding is part of a larger $21 billion bill for several agencies including the IRS, Treasury Department and Securities and Exchange Commission. Noting that it cuts $2.3 billion from the president's overall request, Chairman Hal Rogers said, "the bill focuses cuts on lower-priority or poor-performing agencies, such as the scandal-plagued and inefficient Internal Revenue Service."
