The United States is losing approximately $1 trillion in unpaid taxes every year, Charles Rettig, the Internal Revenue Service commissioner, estimated on Tuesday, arguing that the agency lacks the resources to catch tax cheats.
The so-called tax gap has surged in the last decade. The last official estimate from the I.R.S. was that an average of $441 billion per year went unpaid from 2011 to 2013. Most of the unpaid taxes are the result of evasion by the wealthy and large corporations, Mr. Rettig said.
“We do get outgunned,” Mr. Rettig said during a Senate Finance Committee hearing on the upcoming tax season.
Senator Ron Wyden of Oregon, the Democratic chairman of the committee, called the $1 trillion tax gap a “jaw-dropping figure.”
spending proposal that the Biden administration released last week asked for a 10.4 percent increase above current funding levels for the tax collection agency, to $13.2 billion. The additional money would go toward increased oversight of tax returns of high-income individuals and companies and to improve customer service at the I.R.S.
