CO HB1135

Expands the definition of "dependent" for purposes of the residential retrofit tax credit to include qualifying children, qualifying relatives, and the spouse or civil union partner of the qualified individual.

Allows retrofits that benefit a qualified individual's dependent to qualify for the income tax credit, not just retrofits for the qualified individual alone.

Permits multiple credits per residence if retrofits are required for both the qualified individual and one or more dependents, or for multiple dependents, with a maximum of $5,000 per individual for whom the retrofit is required.

Applies to income tax years from January 1, 2019 through December 31, 2023, with unused credits allowed to carry forward for up to five years.

Effective August 2, 2019, unless subject to referendum petition, in which case effectiveness is contingent on voter approval in November 2020.
