SB/SE Taxpayer Profile

  • Approximately 57 million taxpayers.
  • About 41 million self-employed persons.
  • About 9 million small businesses with assets of less than $10 million.
  • About 7 million filers of employment, excise, estate and gift returns.

The SB/SE Division will serve this taxpayer segment through five organizations:

  • Collection – The mission of Collection is to collect delinquent taxes and secure delinquent tax returns.
  • Compliance Services Campus Operations – This division oversees operations of the Brookhaven, Philadelphia, Cincinnati, Memphis and Ogden Campuses.
  • Examination – It is the function of Examination Division to help taxpayers understand and meet tax responsibilities and apply the tax law with integrity and fairness through Field and Office Audit examinations.
  • Specialty Taxes – Currently there are four market segments for which this division has responsibility. They are Employment Tax, Excise Tax, Estate and Gift Tax and International Tax issues.
  • Communications and Stakeholder Outreach (CSO) – CSO's mission is to develop and deliver integrated strategic communications and educational products to employees and taxpayers and to our key partners in tax administration including practitioners and industry groups.

Comparison of Small Business/Self-Employed (SB/SE) customers to Large Business and International (LB&I) customers:


  • Small businesses (part-time, start-ups)
  • Small businesses without employees (service providers, contractors)
  • Small businesses with employees

  • Individuals investing in businesses (partnerships, S-Corps)
  • Corporations, S-Corporations, & Partnerships with assets less than $10M

  • All 1120 and 1120-S corporations and 1065 partnerships with assets $10 million or more
  • Approximately 210,000 customers

Special Situations
Some businesses may meet the less than $10 million asset test for SB/SE yet be more like a large or midsize business in every other way. These businesses may need the technical expertise of an international examiner, engineer or appraiser. In these situations, the business may be serviced by the Large Business and International Division.

Other businesses may have assets $10 million or more yet be more like a small business. These customers may be serviced by the Small Business/Self-Employed Division.

Over time, IRS expects to develop a comprehensive set of criteria to ensure that the servicing of particular businesses reflects the technical merits of the tax return and the best interests of the business taxpayer.
