CO SB233

Reverses Colorado court of appeals decisions (Oracle Corp. v. Dep't of Revenue and Agilent Technologies, Inc. v. Dep't of Revenue) that excluded holding companies without property or payroll from combined tax reports under section 39-22-303.

Allows C corporations with de minimis or no property and payroll to be included in combined reports and establishes that the Department of Revenue must adopt rules to uniformly apply the de minimis standard.

Treats activities of partnerships and pass-through entities owned more than 50 percent by affiliated group members as activities of those corporate members for purposes of satisfying combined reporting requirements.

Clarifies that only corporations with 80 percent or more of property and payroll located outside the 50 United States and District of Columbia can be excluded from combined reports.

Requires the Department of Revenue to convene a stakeholder working group by September 1, 2019, to discuss tax policies and issues related to combined tax reporting, with findings reported to the legislature.
