SOI Tax Stats - Purpose and Function of Statistics of Income (SOI) Program
The Revenue Act of 1916 mandated the annual publication of statistics related to “the operations of the internal revenue laws” as they affect:
- All forms of businesses
- Nonprofit organizations
- Investments abroad and foreign investments in the United States
SOI fulfills this function by collecting and processing data so that they become informative and by sharing information about how the tax system works with other government agencies and the general public.
Publication types include traditional print sources, Internet files, CD-ROMs, and files sent via e-mail. SOI has an information office, Statistical Information Services, to facilitate the dissemination of SOI data.
Statistical Information Services (SIS):

SOI has four Branches, each responsible for one of the below functional areas:
- Individuals and sole proprietorships
- Corporations and partnerships
- Special studies (including international, tax exempts, and estates)
- Statistical computing, which provides support to the other three Branches, and IRS Operating Division
Each Branch has four Sections. The three subject-specific Branches each have two Sections staffed with economists; one staffed with computer specialists; and the fourth staffed with researchers or information dissemination specialists. The Statistical Computing Branch has two Sections that provide computer support and two that provide statistical support.
How SOI Program Information Is Used
Our annual budget of about $40 million makes us a leading Federal statistical organization. The information we gather, analyze, and publish is used by a variety of Federal agencies, academics, researchers, and curious people. It’s used to analyze tax policy, project tax revenues, and estimate the overall impact of tax law changes and their effects on tax collections.
Our primary clients are the Office of Tax Analysis (OTA) in the Secretary of the Treasury’s Office and the Congressional Joint Committee on Taxation (JCT)—each of whom is entitled to receive detailed tax return files. Most other agencies and individuals can only access data in the aggregate to protect individual privacy as described in Section 6103 of the Internal Revenue Code.
Among some of these other clients are:
- The Department of Commerce's Bureau of Economic Analysis, the Federal Reserve Board, the General Accounting Office, the Social Security Administration, and the Health Care Financing Administration; and
- Tax practitioners, policy researchers, demographers, economic analysts, consultants, business associations, State and local Governments, universities, public libraries, and the media.
