Employer Identification Number

An Employer Identification Number is a nine-digit numeric identifier assigned to business entities for tax administration and reporting in the United States. It is issued by the Internal Revenue Service and is used by a wide range of institutions including banks, state agencies, and federal agencies for identification of entities such as corporations, partnerships, trusts, estates, non-profit organizations, and sole proprietorships. The identifier interacts with statutes, regulations, and systems administered by agencies like the Department of the Treasury and affects filings with bodies such as the Securities and Exchange Commission and state departments of revenue.

History

The origins of the identifier trace to federal tax administration developments following the passage of the Revenue Act of 1913 and subsequent codifications in the Internal Revenue Code. Early numerical schemes evolved alongside systems implemented by the Internal Revenue Service and technological advances at agencies including the Social Security Administration and the Department of the Treasury. Administrative reforms in the 20th century, influenced by events like the Great Depression and the expansion of federal programs under the New Deal, increased the need for standardized business identifiers. Later procedural updates aligned with initiatives by the General Accounting Office and oversight from the Congressional Budget Office. Notable administrative milestones include adaptations following the Tax Reform Act of 1986 and modernization efforts influenced by recommendations from the Government Accountability Office.

Purpose and uses

The identifier serves multiple operational and compliance purposes across a range of institutions. Financial institutions such as Federal Reserve System-regulated banks, Bank of America, JPMorgan Chase, andWells Fargo use it for account opening and reporting to agencies like the Financial Crimes Enforcement Network. Securities market participants including the New York Stock Exchange, Nasdaq, and the Securities and Exchange Commission use entity identifiers in filings. Nonprofit registrants interact with the Internal Revenue Service for tax-exempt recognition under provisions associated with the Internal Revenue Code and filings with the State of Delaware or other state incorporators. Employers use it for wage reporting to the Social Security Administration and for payroll tax filings to the Internal Revenue Service. It is employed by federal contractors when registering with systems like the System for Award Management and appears on forms submitted to agencies such as the Department of Labor and the Occupational Safety and Health Administration.

Application and assignment

Applications are filed through channels administered by the Internal Revenue Service and may involve interaction with entities such as the U.S. Department of State for foreign-owned entities and the U.S. Citizenship and Immigration Services where employment sponsorship intersects. Issuance procedures have been influenced by electronic government initiatives exemplified by the IRS e-file system and the United States Digital Service. Requests require verification documents often similar to those filed with secretaries of state, including registries like the New York Department of State and the California Secretary of State. Assignment rules reflect entity classification outcomes under guidance from the Internal Revenue Service and may involve legal forms overseen by the United States District Court in bankruptcy or structural reorganization cases, such as those involving Enron or Lehman Brothers.

Structure and format

The identifier follows a nine-digit numeric format divided in presentation into two groups: the first two digits and the remaining seven digits. Historically, the first two-digit prefixes have been associated with regional processing centers and internal coding practices at the Internal Revenue Service, similar in concept to earlier routing schemes used by the Federal Reserve and postal coding systems like the United States Postal Service. Presentation of the number on forms aligns with reporting standards used by the Internal Revenue Service, the Securities and Exchange Commission, and financial institutions, and appears on documents such as tax returns filed by entities like General Electric and ExxonMobil.

Changes, reissuance, and cancellations

Rules for changing or reissuing identifiers are set by the Internal Revenue Service and may be invoked in circumstances such as mergers overseen by regulators like the Federal Trade Commission or asset transfers approved by the Securities and Exchange Commission. Court-ordered reorganizations, including cases adjudicated in the United States Bankruptcy Court system, can trigger reassignment or cancellation. Transfers of ownership or structural conversions, as seen in corporate reorganizations of firms like AT&T or General Motors, interact with assignment rules administered by state authorities such as the Delaware Court of Chancery and federal tax treatment defined under the Internal Revenue Code.

Legal and tax implications

Possession and use of the identifier entails obligations under statutes and regulations enforced by the Internal Revenue Service, the Department of Labor, and agencies like the Equal Employment Opportunity Commission when reporting employment data. Misuse or fraud can prompt investigations by the Federal Bureau of Investigation and civil enforcement by the Internal Revenue Service and the Department of Justice. The identifier figures in compliance regimes including tax-exempt determinations under provisions cited by the Internal Revenue Service and disclosures required by the Securities and Exchange Commission for public companies such as Apple Inc. and Microsoft Corporation.

International considerations and privacy

Cross-border entities interact with foreign authorities such as the Canada Revenue Agency, the Her Majesty's Revenue and Customs, the European Commission, and the Organisation for Economic Co-operation and Development when reconciling identifiers for multinational operations. Privacy considerations involve statutes like the Privacy Act of 1974 and data-protection frameworks influenced by the European Union and agreements such as the U.S.–EU Data Privacy Framework. Institutional actors including multinational banks like Citigroup and HSBC and international standard-setters such as the International Organization for Standardization influence practices for handling entity identifiers in global information exchanges.
