Executive, Legislative, & Other General Government Support
NAICS 921: Executive, legislative, and general government support. IRS, Congress, OMB, Census Bureau, and tax administration.
Industry Overview
Executive, legislative, and other general government support (NAICS 921) covers the core institutional machinery of governance: executive offices at federal, state, and local levels; legislative bodies; and cross-cutting administrative agencies that provide financial management, personnel administration, tax collection, and program oversight for the broader government apparatus.
At the federal level, the Executive Office of the President, Congress (535 elected members plus approximately 30,000 staff), and agencies like the Office of Management and Budget (OMB), Office of Personnel Management (OPM), and the General Services Administration (GSA) define the subsector's institutional core. The IRS, the largest revenue-collection agency, processes over 160 million individual tax returns annually and has received $80 billion in supplemental funding under the Inflation Reduction Act for enforcement modernization, IT upgrades, and taxpayer services. State equivalents include governors' offices, state legislatures (over 7,000 state legislators nationwide), and departments of revenue that collectively administer state income, sales, and property tax systems.
The Census Bureau, Bureau of Labor Statistics (BLS), and Bureau of Economic Analysis (BEA) fall within this subsector's statistical infrastructure, producing foundational economic data including GDP estimates, unemployment figures, and the decennial census that determines congressional apportionment and federal funding allocation formulas. The Government Publishing Office (GPO) handles the Federal Register, Code of Federal Regulations, and congressional publications. These information-producing functions make the subsector's outputs foundational to private-sector decision-making despite its relatively small direct employment footprint.
