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 San Juan County Assessor.
Relief programs
The filing guidance for this county is: July 15, 2026 for the Colorado Senior Homestead Exemption; San Juan County's exemption information identifies the senior deadline and county assessor process. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationSan Juan County follows Colorado's senior homestead program: generally age 65+ on January 1, ownership and primary-residence occupancy for at least 10 consecutive years, and 50% of the first $200,000 of actual value exempt when funded. Applications are generally due July 15.
No annual assessment-growth cap published; San Juan County says state statutes require market-value appraisal and its appeal page states there is no current limit to how much value may increase.
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 4 through June 8, 2026; San Juan County's official appeal page identifies May 4 as the 2026 protest start and June 8 as the deadline. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
