SOI Tax Stats - Business Tax Statistics


Each year SOI produces studies that provide statistics on income, deductions, taxes, credits, and more reported by businesses. Select the subject areas below that interest you.

Integrated Business Data (IBD)

This section contains statistical tables and articles on all businesses, which were compiled to form the SOI Integrated Business Dataset (IBD). The IBD was assembled at the table level from the annual SOI cross-sectional studies of corporations (C and S corporations), partnerships, and nonfarm sole proprietorships. The dataset combines data from these types of organizations to enable examination of changes in business composition. Data from these annual statistical studies are generally publicly available and are published in a variety of SOI reports.

Payroll Statistics

These data are based on the population of Form 941 returns received and processed by the IRS, shown as reported by the taxpayer before IRS examination.  A substantial majority of employers file Form 941. However, the IRS also collects payroll tax information from employers through the following IRS Forms: Form 943, 944, and CT-1.

S Corporations

S corporations are domestic corporations that elect to be taxed individually on the corporation's income; they can have no more than 100 shareholders (only U.S. citizens, resident aliens, estates, certain trusts, and exempt organizations) and one class of stock. These corporations file on Form 1120-S. Look here for statistics and related information on these corporations.
