As much as half a trillion in unpaid taxes every year makes our budget deficit far worse
- An estimated $400 billion to 500 billion in taxes go uncollected every year in the United States because of tax evasion and noncompliance. 
- The United States loses some $100 billion more in tax revenues annually because of offshore tax abuses by wealthy individuals and corporations.
- This yawning “tax gap” increases the deficit and undermines the faith of honest taxpayers who don’t cut corners.
Every additional $1 invested in tax enforcement and compliance can shrink the deficit by at least $3
- President Barack Obama’s proposal to invest an additional $13 billion in IRS enforcement and compliance activities over the next decade will generate more than three times that amount in additional revenues—$42 billion, according to official estimates.
- The funding will allow the IRS to contact potentially noncompliant taxpayers that “it currently identifies but cannot contact given resource constraints” and strengthen pre-refund compliance checks, according to the Government Accountability Office.
- Better enforcement leads to greater compliance: After the IRS in recent years began targeting people using offshore bank accounts to evade taxes, about 19,000 taxpayers entered a voluntary compliance program and paid billions in back taxes and penalties.
Efforts to cut the IRS will only make the budget deficit worse
- A bill moving through Congress would slash IRS funding by more than $600 million and lead to the furlough of 4,100 to 5,000 employees, mostly enforcement agents.
- “Cuts of this magnitude would be substantial and affect all of IRS operations,” from answering taxpayers’ questions on the phone to conducting audits, according to IRS Commissioner Douglas Shulman.
- Not only would cutting the IRS benefit tax cheats, it would make it harder for honest taxpayers “to understand and comply with changes in the tax law . . . as well as to successfully resolve pre-filing, filing and post-filing tax matters,” according to a recent report by law firm K&L Gates.

. The IRS estimated that in 2001, the “net tax gap"—the difference between what is owed in taxes and what is actually paid (including after IRS enforcement actions)—was nearly $300 billion. Assuming that the tax gap has expanded at the same rate as the overall economy over the last decade, it would stand at between $400 billion to 500 billion today.
