That's my reaction to this request from President Biden which was included in his 2022 budget outline:
Supports a Fair and Equitable Tax System. To ensure that all Americans are treated fairly by the Nation’s tax system, including that the wealthy and corporations comply with existing laws, the discretionary request provides $13.2 billion for the Internal Revenue Service (IRS), a $1.2 billion or 10.4-percent increase above the 2021 enacted level. With this funding, the IRS would: increase oversight of high-income and corporate tax returns to ensure compliance; provide new and improved online tools for taxpayers to communicate with the IRS easily and quickly; and improve telephone and in-person taxpayer customer service, including outreach and assistance to underserved communities. In addition to increases for base IRS enforcement funding, the 2022 discretionary request provides an additional increase of $417 million in funding for tax enforcement as part of a multiyear tax initiative that would increase tax compliance and increase revenues. Altogether, the 2022 discretionary request would increase resources for tax enforcement by $0.9 billion
I'd prefer a multi-year plan for 50 percent for more.
