San Juan County, Utah property-tax payment and appeal deadlines

Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The reviewed record below separates published figures from items that still require confirmation with San Juan County Assessor.

Rate context

Confirm

no single verified 2026 countywide effective rate; Utah property-tax rates vary by tax area and taxing entity.

Statement mailing

Published

October 1, 2026 (county schedule; actual date may be set by the Clerk).

Payment deadline

Published

2026 Utah real-property taxes are due on or before November 30, 2026; taxes unpaid after November 30 (or the next business day when applicable) are delinquent and subject to statutory penalty and interest.

Valuation protest

Published

September 15, 2026 or within 45 days of mailing the 2026 Notice of Valuation, whichever is later; San Juan County's 2026 relief page publishes this BOE rule.

Do not assume a grace period.

The reviewed 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 a published payment deadline as a hard operational date and retain your receipt or confirmation number.

From assessment to collection

01Valuation 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.

02Statement and account review

Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.

03Payment 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.
