CO HB1175

Adds oil and gas surface equipment installation and operation on agricultural land as a valid reason for property tax valuation objections and protests.

Requires taxpayers objecting to rent-producing commercial real property valuations in counties with extended appeal timelines to provide rent roll data to assessors by July 15 (instead of waiting until the 90-day appeal period).

Extends the deadline for assessors to mail denial decisions from the last working day in August to August 15 for counties that have elected extended appeal timelines.

Exempts petitioners who already provided rent roll information to assessors under the new July 15 deadline from having to resubmit the same information during the 90-day appeal period.

Requires counties to disclose the primary valuation method and rates used to determine commercial property values (rather than all underlying data including capitalization rates) when responding to petitioner requests for valuation information.
