2026 fiscal calendar
Know the tax date before it becomes a penalty date.
Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The verified record below separates published figures from dates that require confirmation with San Miguel County Assessor.
Effective rate
Approximately 0.32397% in San Miguel County's official Town of Telluride example ($1,619.84 tax on $500,000 actual value); actual total rates vary by tax area and taxing districts.
Statement mailing
End of January 2027; San Miguel County's official Tax Statement Mailing page says statements are mailed at the end of January, while the Treasurer overview says the first part of February.
Payment deadline
For 2026 property taxes payable in 2027: first half due February 28, 2027; full payment due April 30, 2027; second half due June 15, 2027. San Miguel County states delinquent interest is 1% per month after the applicable deadline.
Valuation protest
May 1 through June 8, 2026; San Miguel County's official 2026 appeal materials identify this valuation protest window.
Critical payment warning
Do not assume a grace period.
The verified county record identifies the payment timing above but does not establish a universal penalty schedule for this page. Late charges, interest, collection costs, tax-sale procedures, and lien or foreclosure timelines can depend on state law and the local collector’s process. If the deadline is close or a balance is delinquent, contact the tax collector directly and request the current payoff amount in writing.
Treat the published payment deadline as a hard operational date and retain your receipt or confirmation number.
Read the calendar in order
From assessment to collection
1. Valuation and notice
Review the assessment notice as soon as it arrives. The protest window may run from the notice date rather than from the payment due date.
2. Statement and account review
Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.
3. Payment confirmation
Use the official collector channel, then save the receipt, transaction reference, and date posted. A bank submission is not always the same as a county posting date.
