Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Montrose County Assessor.
Relief programs
The filing guidance for this county is: July 15, 2026 for the 2026 Senior Homestead Exemption application; Montrose accepts late applications through August 17, 2026 without appeal rights. The Qualified Senior Primary Residence Classification deadline is March 16, 2026. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationMontrose County's senior exemption follows Colorado's program: generally age 65+ as of January 1, ownership and primary-residence occupancy for at least 10 consecutive years, and 50% of the first $200,000 of actual value exempt. The county's 2026 page confirms program funding and the July 15 deadline.
Colorado has no Proposition 13-style annual homestead assessment-growth cap. Real property is revalued under Colorado's statutory reassessment cycle, and local tax bills vary by taxing district, mill levy, and statutory assessment rate.
Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: May 1 through June 8, 2026; Montrose County's official 2026 tax insert identifies this real-property protest period. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
