Matanuska-Susitna Borough, Alaska property-tax rates and 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 Matanuska-Susitna Borough Assessments Division.
Rate context
Published0.8485% areawide equivalent for FY2026 (8.485 mills); city, service-area, and other tax-zone rates vary.
Statement mailing
PublishedJuly 1, 2026.
Payment deadline
PublishedFirst installment due August 17, 2026; second installment due February 16, 2027, according to the current official 2026 property-tax page. Verify the installment date printed on the bill if the page displays stale labels.
Valuation protest
PublishedWithin 30 days from the date the assessment notice was mailed; the official Board of Equalization page states this statutory window but does not publish a single 2026 calendar date.
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.
