How to Appeal Your Property Tax in Alaska: Step-by-Step Guide for 2026

An Alaska property-tax appeal is heard by the board of equalization of the borough or city that assessed you. Under AS 29.45.190(b) you have 30 days after the date your notice of assessment was mailed to give the assessor a written appeal; after that the right to appeal “ceases” unless the board finds you were unable to comply.

Alaska appeal deadlines at a glance

The statute counts from the mailing date, not from the day the envelope reaches you. AS 29.45.170(b) says a notice “is effective on the date of mailing,” and a mailed notice is sufficient if it goes out by first class mail 30 days before the equalization hearings. Anchorage tells owners that an appeal must be “received by the Property Appraisal Division, or postmarked, by the ‘Appeal must be filed by’ date shown on the face of the assessment notice.” Your own notice is where to read your date. A disaster reassessment notice is the exception: under AS 29.45.230(c) you have only 10 days to appeal it.

Which board hears you: borough, city or unified municipality

Property tax in Alaska is a local tax. AS 29.45.010 lets unified municipalities, boroughs and cities levy it, and when they do, it “must be assessed, levied, and collected as provided in this chapter.” The appeal sections are part of that chapter, and AS 29.10.200(55) lists AS 29.45.010 through 29.45.560 among the provisions that bind home rule municipalities too. Anchorage and the Fairbanks North Star Borough therefore work inside the same 30-day rule. Their calendar dates differ because each mails its notices on its own schedule.

The board itself changed shape on January 1, 2025. SB 179 (chapter 28, SLA 2024) rewrote AS 29.45.200(a): the governing body “shall appoint one or more boards of equalization,” each of at least three people drawn from the governing body, municipal residents or both, and it may sit as the board itself only if an ordinance says so. Above the board, AS 29.45.210(d) sends a disputed decision to the superior court. A separate question, whether property is taxable at all, may go to the superior court directly under AS 29.45.200(c).

Anchorage and Fairbanks: two local calendars under one statute

These details come from each municipality’s own pages and apply only there.

• Municipality of Anchorage. Valuation notices “must be sent out on or before January 15th.” For the 2026 roll the Property Appraisal page said “most appeals must be filed by February 11, 2026.” Filing takes a written form plus a refundable deposit scaled to assessed value: $30 under $100,000, $100 up to $499,999, $200 up to $1,999,999 and $1,000 above that. Under AMC 12.05.055 B, the deposit comes back if the appeal settles before the hearing, or if you show up and take part after giving the assessor the data and access it asked for. Evidence is due within 45 days of the mailing date unless the assessor agrees to extend.
• Fairbanks North Star Borough. Assessment notices go out “at the end of January each year,” and appeals “must be filed in-person or postmarked within 30 days from the mailing date.” Borough code 8.16.010 defines “inability to comply” narrowly: a “serious medical or other similar serious condition or event beyond the taxpayer’s control.” Failing to pick up mail, or to keep your address current with the assessor, does not qualify.

Other boroughs publish their own dates. None of these local figures is a statewide rule.

What the board may decide after the 2025 amendments

AS 29.45.210(b) puts the burden of proof on you. The only grounds for an adjustment are “proof of unequal, excessive, improper, or under valuation based on facts that are stated in a valid written appeal or proven at the appeal hearing.” SB 179, effective January 1, 2025, rewrote one sentence and added another:

• The board “may not raise the assessment in the current year unless requested to do so by the appellant.” Before 2025 the statute let the board raise a value it found too low.
• If you support your value with “a long form fee appraisal” and lose, the board must “make specific findings on the record to support its decision.”

The board may change the assessment of a lot “only pursuant to an appeal filed as to the particular lot” (AS 29.45.200(b)), so a neighbor’s appeal does nothing for your parcel. A superior court appeal is heard “on the record established at the hearing before the board of equalization.” Anything you want a judge to see later has to go in front of the board first.

Anchorage’s FAQ adds its own standard: appellants “must present clear and convincing evidence.” Fairbanks cites the statutory burden in AS 29.45.210(b).

Evidence Alaska assessors say they weigh

Both large municipalities give the same answer for houses. Anchorage: “In a residential appeal the best evidence of market value is sale price, the sale price of the subject property, and of similar properties.” Fairbanks lists fee appraisals, listings, closing statements, inspection reports and repair estimates as supporting material. The value under review is the “full and true value as of January 1 of the assessment year” (AS 29.45.110(a)). Sales around that date say more about it than a sale this summer.

Tax amount, mill rate and the size of the increase are not grounds. Anchorage says so directly: “appeals may only be made against the value of the property.”

Paying the bill while an appeal is open

The payment rules during an appeal come from the municipalities. Anchorage: “Taxes must be paid on or before the due date even if an appeal is pending.” Its exception covers residential property whose value rose $50,000 or more (commercial: $250,000) with no new construction on record. Those owners pay a minimum installment based on last year’s value and this year’s mill rate. Fairbanks: “Taxes must be paid by the due date, even if an appeal is pending.” Anchorage refunds the excess, with interest, when a Board of Equalization appeal ends in a lower value.

Frequently asked questions

I missed the 30 days. Is there any way back in?

Only one: the board of equalization has to find that you were “unable to comply” (AS 29.45.190(b)). The statute does not define that phrase, so ask your own borough or city how it applies it. Fairbanks North Star Borough spells it out in its code: it requires an affidavit filed within 30 days after the appeal period closes and rejects excuses like unread mail. A late appeal with no finding is barred for that year.

Could the board raise my value because I appealed?

Not since January 1, 2025, unless you ask it to. The amended AS 29.45.210(b) says the board “may not raise the assessment in the current year unless requested to do so by the appellant.”

Does a Board of Equalization win carry over to next year?

Not in Anchorage. Its FAQ says a decision “is only applicable for the tax year in which an appeal is filed,” and the assessor is not bound by it the following year. Check each new notice and appeal again if needed.

Is there a state board above my borough’s board?

For a homeowner’s valuation dispute, the step after the local board that AS 29.45.210(d) names is the superior court. Under Appellate Rule 602(a)(2), the 30 days to appeal start only once the decision “clearly states that it is a final decision and that the claimant has thirty days to appeal.”

Do I need to talk to the assessor before filing?

AS 29.45.180(a) says a person receiving a notice “shall advise the assessor of errors or omissions,” and gives you the right to a meeting on request. That meeting does not stop the 30-day clock in AS 29.45.190(b). If the talk has not settled things by the deadline, file the written appeal anyway.
