WASHINGTON—The U.S. government is losing some $1 trillion in unpaid taxes every year and needs more and consistent Internal Revenue Service funding to go after tax cheats, IRS Commissioner Charles Rettig said on Tuesday.
Rettig told the Senate Finance Committee that the “tax gap”—the difference between taxes legally owed and revenue collected—has grown substantially since the last official estimate of a $441 billion annual average from 2011 to 2013.
