How Much Can Property Taxes Increase in Alaska? 2026 Complete Guide
Updated July 2026
Quick Answer
Alaska puts no cap on how much your assessed value can rise in a year. Property is assessed annually at full market value, and there is no state property tax on homes: property tax in Alaska is levied only by municipalities. The limits that do exist sit on the levy side, in AS 29.45.090: a municipality cannot levy property taxes above 3% of assessed value (30 mills) in a year, a per-capita revenue ceiling applies on top of that, and second class cities are capped at 2% (20 mills). Relief comes through exemptions, most importantly a mandatory exemption on the first $150,000 of assessed value for homeowners 65 and older and for disabled veterans with a 50% or greater service-connected disability.
If your assessment jumps, your remedy is not a cap. It is a written appeal to your local Board of Equalization within 30 days of the assessment notice mailing.
Most homeowners never challenge their assessment, usually because nobody tells them they can or shows them how. That gap is the whole reason AppealDesk exists: see what your county has your home on record at, free, and if the number looks wrong we build the case for $49.
Does Alaska Have an Assessment Cap?
No. Alaska is one of the states with no statutory limit on year-over-year assessment increases. Assessors are required to value property annually at market value, and if the market says your home is worth 15% more than last year, your assessment can rise 15% in one cycle. There is no phase-in, no percentage ceiling, and no protection tied to how long you have owned the home.
It is worth being precise about what Alaska does not have, because generic property tax advice often assumes cap-state rules that simply do not exist here. Alaska has no acquisition-value system like California's, so your taxable value does not reset only when you buy. It has no homestead assessment cap like Florida's Save Our Homes. And nothing changes when a property sells or transfers: there is no protected value to lose, because there was never a protected value in the first place. Every owner, new or longtime, is assessed on the same market-value basis every year.
That design is deliberate. Alaska prioritizes market-based assessments and local control, which keeps new and existing owners on an equal footing. The tradeoff is that nothing in the system automatically shields you from a fast-appreciating market, or from a mass-appraisal model that simply gets your house wrong.
What Is Alaska's Property Tax Rate in 2026?
There is no single Alaska property tax rate, because the state itself does not tax homes at all. Property tax is a municipal tax, levied by boroughs and cities that have chosen to adopt one. Each taxing municipality sets its own mill rate every year through its budget process, so the rate on a home in Anchorage is different from the rate in Fairbanks North Star Borough, Juneau, or Kodiak.
One feature of Alaska surprises people from other states: only a minority of Alaska municipalities levy a property tax at all. Large portions of the state sit in the unorganized borough, outside any property-taxing municipality, and homeowners there pay no property tax. If you do get an assessment notice, though, you live somewhere that taxes, and the numbers on that notice are what your bill is built from.
What the state does impose is an outer boundary on rates, described in the next section. Inside that boundary, your actual mill rate is a local decision, and the only way to know your 2026 rate precisely is to check your borough or city assessor's published rate for your service area.
Alaska's Levy Limits: The 30-Mill Cap and Per-Capita Ceiling (AS 29.45.090)
The statewide limits Alaska does have live in AS 29.45.090, and they constrain the taxing government, not your individual assessment. First, a municipality may not levy property taxes exceeding 3% of the assessed value of property in the municipality in a year. That is the 30-mill cap. Taxes levied for bonded debt and voter-approved service-area taxes are excluded from the cap, so a bill in a borough with bonds and service areas can reflect levies beyond the 30-mill operational ceiling.
Second, the same statute imposes a per-capita revenue limit: a municipality's property tax revenue is capped by a sliding-scale formula tied to average per-capita assessed value multiplied by population, with a flat $1,500-per-resident alternative available. In practice the sliding scale is usually the operative limit. Third, second class cities face a tighter ceiling and may not levy property taxes above 2% of assessed value (20 mills). Compliance with these limits is enforced by the Office of the State Assessor under AS 29.45.103 and 29.45.105.
To see what the 30-mill cap means in dollars, take a $300,000 home. Three percent of $300,000 is $9,000, so that is the statutory outer bound on the general levy against that home. Most homeowners will never approach it, because their municipality's actual mill rate sits well below the cap. And that points to the cap's real limitation for you as a homeowner: it constrains the rate, not the value the rate is multiplied against. If your assessment climbs from $300,000 to $360,000, every one of those extra $60,000 is fully taxable at whatever rate your municipality sets. The levy limit never asks whether $360,000 was the right number.
Caps and rate limits only control how fast your bill can grow. Nothing in them checks whether the number underneath is right. Assessors in Alaska set values with mass-appraisal models that price thousands of homes at once, and nobody reviews yours unless you challenge it.

Do Property Taxes Go Up Every Year in Alaska?
They can, and in a rising market they usually do. Because reassessment is annual and uncapped, your assessed value tracks the market each year, and your bill moves with two independent levers: the value your assessor assigns and the mill rate your municipality adopts. Either one can push the bill up. A borough can hold its mill rate perfectly flat and still collect more from you if assessments rose, and that increase requires no vote and no public hearing on your particular home.
The arithmetic is straightforward. A home assessed at $300,000 that gets revalued at $330,000, a 10% increase, will see a 10% larger bill at an unchanged mill rate. The per-capita revenue ceiling in AS 29.45.090 puts some drag on total municipal collections, but it operates at the level of the whole municipality's revenue, not your parcel. Nothing in it prevents your individual assessment, and therefore your individual bill, from rising faster than your neighbors'.
The practical takeaway: in Alaska, budgeting for property taxes means watching your assessment notice, not just the mill rate headlines. The notice is where your increase actually happens.
The $150,000 Senior and Disabled Veteran Exemption
Alaska's most important homeowner relief is not a cap but a mandatory statewide exemption under AS 29.45.030(e): the first $150,000 of assessed value on the primary residence is exempt for homeowners 65 and older and for disabled veterans with a 50% or greater service-connected disability. Surviving spouses who are at least 60 also qualify. Every property-taxing municipality must honor it.
The effect is large. For a qualifying senior with a home assessed at $300,000, the exemption removes half the taxable value, which cuts the bill in half at any given mill rate. For a home assessed at $150,000 or less, the bill goes to zero. Note that a 2024 Senate Finance proposal to raise the exemption to $450,000 (alongside HB 347) was introduced but has not been confirmed as law, so $150,000 remains the number to rely on.
On top of the mandatory exemption, municipalities may offer an optional residential exemption under AS 29.45.050 to all homeowners. The Kenai Peninsula Borough is a live example: in October 2025 borough voters raised its optional residential exemption from $50,000 to $75,000, with applications due before February 16, 2026. Whether your municipality offers an optional exemption, and at what amount, is a local question, so check with your borough or city assessor.
New in 2024-2026: SB 179 and HB 13 (What Changed)
Two recent laws are worth knowing. SB 179, signed August 13, 2024, prohibits municipalities from levying real estate transfer taxes, so no Alaska borough or city can add a tax on the sale of your home. The same bill improved the farm-use property tax break program, allowed municipalities to defer taxes on economic-development property, and tightened both assessor qualifications and the property tax appeal process.
HB 13 became law on June 22, 2026, effective September 20, 2026. It authorizes municipalities to adopt new optional property tax exemptions: for first-time homebuyers, long-term rental units and conversions of short-term rentals to long-term use, mobile home parks, low-income rental housing, and volunteer firefighters and EMS providers. The key word is optional. HB 13 creates no statewide exemption on its own; it gives your local assembly or council new tools it may or may not use. If one of those categories fits you, it is worth asking your municipality whether it plans to adopt the corresponding exemption.

Alaska: Mill ceiling. That is a different kind of limit from the bars above, which cap the assessment itself.
AS 29.45.090 caps the levy at 30 mills, with a per-capita revenue ceiling on top.
A cap limits how fast the number grows. It does not check whether the number was right to begin with.
What you can do about it
How to Appeal Your Alaska Assessment (30-Day Board of Equalization Deadline)
Because Alaska has no assessment cap, the appeal process is the only mechanism that reviews whether your assessed value is actually right. Under AS 29.45.190, you appeal in writing to your municipality's Board of Equalization within 30 days after the mailing of the annual assessment notice. That 30-day pattern holds across Anchorage, Fairbanks North Star Borough, Juneau, Ketchikan, and Kodiak. Miss the window and the value generally stands for the year, so the clock that starts when the notice hits the mail is the single most important date in the Alaska property tax calendar. If the assessor later issues a corrected notice, a new 30-day window runs from that corrected notice.
The burden of proof is on you, the appellant. It is not enough to say the value feels high; you need evidence that the assessor's market-value estimate is wrong, which usually means recent sales of comparable homes, documentation of condition problems the model could not see, or errors in the property record itself, such as wrong square footage or a garage that does not exist. A well-documented appeal is how an uncapped assessment gets corrected before it compounds into years of overpayment.
A real AppealDesk order, King County, Washington
In June 2026, a homeowner in King County, Washington ran the check. The county had their home on record at $2,220,000, while recorded sales of comparable homes supported about $1,682,489: an over-assessment of $537,511, worth roughly $4,757 per year if corrected. Their packet laid out the comparable sales, the forms, and the filing steps. Nobody at the county was ever going to run that check for them.
Growth limits only help if the number they grow from is fair. If your assessment jumped after a purchase, new construction, or a revaluation, that new number is the one nobody has reviewed. Checking it is free and takes about a minute.

Frequently Asked Questions
How much can my Alaska property taxes increase this year?
There is no statewide limit on how much your assessment, and therefore your bill, can increase in a year. Your assessed value follows the market, and your municipality sets the mill rate within the AS 29.45.090 ceilings (3% of assessed value for the general levy, 2% in second class cities, plus the per-capita revenue limit). If your value rose sharply, the appeal process, not a cap, is your remedy.
How often is my property reassessed in Alaska?
Annually. Every property-taxing municipality assesses property at market value each year and mails an assessment notice, and each notice opens a fresh 30-day appeal window to the Board of Equalization.
Does my assessment reset when I buy a home in Alaska?
No. Alaska has no sale-triggered reassessment rules and no ownership-duration protections, because there is no acquisition-value or capped-value system to reset. Buyers and longtime owners are assessed on the same annual market-value basis. And thanks to SB 179 (2024), municipalities cannot charge a real estate transfer tax on the purchase itself.
Why doesn't Alaska cap assessment increases like other states?
Alaska prioritizes market-based assessments and local control, which keeps new and existing owners paying on the same basis. Relief is delivered through exemptions instead, chiefly the mandatory $150,000 senior and disabled-veteran exemption, plus optional local exemptions under AS 29.45.050 and, starting September 2026, the new optional categories authorized by HB 13. It is also worth remembering that much of the state, in the unorganized borough, pays no property tax at all.
What is the best way to control my property tax increases in Alaska?
Review your assessment notice the week it arrives, compare the value against recent sales of similar homes, and file a written appeal within the 30-day window if the number looks high. At the same time, claim every exemption you qualify for: the mandatory $150,000 senior or disabled-veteran exemption if eligible, and any optional residential exemption your municipality offers. Because reassessment is annual, you get a new opportunity to do both every year.
