Section 14-15-117 - Application of article to joint tax returns - legislative declaration(1) The general assembly finds that some partners in a civil union may legally have their federal taxable income determined on either separate federal tax returns or on a joint federal tax return. Since Colorado income tax filings are tied to the federal income tax form by requiring taxpayers to pay a percentage of their federal taxable income as their state income taxes:(a) Partners in a civil union who have their federal taxable income determined on separate federal tax returns must have such income separately determined for purposes of the Colorado income tax; and(b) Partners in a civil union who have their federal taxable income determined on a joint federal tax return must have their state taxable income determined based on their joint federal taxable income.Amended by 2014 Ch. 10,§ 1, eff. 2/27/2014.Added by 2013 Ch. 49,§ 1, eff. 5/1/2013.L. 2013: Entire article added, (SB 13-011), ch. 49, p. 155, § 1, effective May 1.
