The Illinois Department of Revenue has issued the new income rates for individuals and businesses effective for income received on or after January 1, 2015.

The following is a summary of the rates:

  • For individuals, trusts and estates – new rate is 3.75% (decrease from 5% rate).
  • For Corporations (excluding S-Corporations) – new rate is 5.25% (decrease from 7% rate).
  • Fiscal year end filers – must divide total net income between the periods subject to the different rates. Amounts earned prior to January 1, 2015 are taxed at 5% (individuals, trusts and estates) and 7% (corporations). The amounts earned on or after January 1, 2015 are taxed at 3.75% (individuals, trusts and estates) and 5.25% (corporations).

There is no change to the Illinois Replacement Tax rates. The rates remain the same; 2.5% for corporations and 1.5% for S-corporations, trusts and partnerships.

Since exempt organizations are classified as either trusts or corporations, the new income tax rates apply to these organizations with unrelated business income in Illinois.
