In 2017, average household income before accounting for means-tested transfers and federal taxes was $21,300 for the lowest quintile and $309,400 for the highest quintile. After transfers and taxes, those averages were $35,900 and $229,700.

By providing financial support to households, businesses, and state and local governments, federal laws enacted in response to the 2020 coronavirus pandemic will offset part of the deterioration in economic conditions brought about by the pandemic.

The average error for CBO’s budget-year revenue projections is 1.2 percent, indicating the agency has tended to slightly overestimate revenues. For the agency’s sixth-year revenue projections, the average error is greater—5.6 percent.

CBO examines the IRS’s enforcement activities between 2010 and 2018 and analyzes how the decline in those activities reflects the decline in its funding and staff over that period. CBO also estimates how changes to the IRS’s budget could affect federal revenues.

CBO has reduced its projections of corporate income tax receipts for the 2020–2029 period by $127 billion (or about 4 percent). That change from the agency’s August 2019 projections arose from several sources.

CBO examines the tax benefit of having dependents under current law in 2019 and 2026 and analyzes how three policy options that would simplify dependent-related tax provisions would affect that benefit.

In this report, CBO projects, on the basis of current law, marginal federal tax rates on labor income from 2018 through 2028. So that current trends can be understood in a historical context, the projections are accompanied by rates from 1962.
