Review your assessment notice when received (timing varies by borough - Anchorage and Mat-Su typically mail notices January-February)
Contact the borough assessor's office informally first - most boroughs offer an informal review process before formal filing; this is recommended and often resolves disputes without a formal hearing
If unresolved informally, file a written appeal with the Borough Board of Equalization within 30 days of receiving your assessment notice (Alaska state law - AS 29.45.190)
Gather supporting evidence: comparable sales data, recent appraisal, photos, or other documentation showing your property's true market value
Attend your Board of Equalization hearing and present your evidence; you bear the burden of proof
Receive the Board's written decision
If still unsatisfied, appeal to Alaska Superior Court within 30 days of the Board's final decision

Alaska Notes
Important state-specific details
Alaska state law (AS 29.45.190) requires written appeal within 30 days of receipt of assessment notice - this is a hard deadline.
The appellant bears the burden of proof - "value is too high" without evidence is not sufficient; must show comparable sales, factual errors on property record, or other documented evidence.
As of 2025 state law update: neither the assessor nor the Board of Equalization can raise a property's assessed value during the appeal - appeals carry no risk of a higher assessment.
Alaska is a non-disclosure state - sales data is voluntarily reported; gathering your own comparable sales data is important for building your case.
Senior/disabled exemption (up to $150,000 assessed value): if you haven't applied, do so through your borough assessor - this is separate from an appeal but may reduce your tax significantly.
Property tax is borough-level only in Alaska - there is no state property tax to appeal.
