Alaska property tax rates vary by borough because the state itself levies no property tax on homes. Each organized borough and city sets its own mill rate, and most residential parcels in the three largest boroughs fall between roughly 9 and 16 mills once service area levies are added. Large portions of the state sit in the unorganized borough and pay no property tax at all. The statewide average effective rate lands near 0.94 percent of home value.
Why Rates Are Set Locally
Alaska has no statewide income tax and no state-level sales tax.1Alaska Department of Commerce, Community, and Economic Development. Office of the State Assessor – Alaska Tax Facts Property tax is the main revenue tool for local governments, funding schools, roads, fire protection, and emergency services. Alaska Statute 29.45.010 grants the power to levy property tax to municipal governments only, not the state.2Municipality of Anchorage. Property Tax Law Excerpts So the rate on your home comes from your borough assembly, and often from smaller service areas within it.
How Mill Rates and Service Areas Stack
Alaska boroughs express rates in mills. One mill equals one dollar of tax per thousand dollars of assessed value. A home assessed at $300,000 in a 15-mill district owes $4,500 a year.
Your total rate is rarely a single number. It stacks an areawide rate every property in the borough pays, plus additional levies for the specific service areas your parcel sits inside. A home with city police coverage, street lighting, and fire protection carries more service area mills than a rural parcel that gets only basic road maintenance. Two houses of identical value a few miles apart can owe noticeably different amounts because their service boundaries differ.3Alaska Department of Commerce, Community, and Economic Development.

Rates in the Major Boroughs
Municipality of Anchorage
Most Anchorage homes pay total mill rates between roughly 14 and 16 mills. Properties in the core city service area tend to land near 15.8 mills. Homes in outlying limited road service areas or the Chugiak-Eagle River corridor pay somewhat less, with some areas dipping to about 13.8 mills.4Municipality of Anchorage. 2025 Mill Rates On a $350,000 home, the gap between a 14-mill and 16-mill district is about $700 a year.
Fairbanks North Star Borough
The Fairbanks North Star Borough sets an areawide mill rate of about 10.6 mills covering general government and education. Parcels outside the City of Fairbanks also pay a non-areawide levy and a solid waste collection district levy, bringing the base to roughly 12.9 mills before service areas are added.5Fairbanks North Star Borough. Resolution 2025-20 Substitute Attachment A Service area levies run from under 1 mill to over 5 mills for most neighborhoods, putting typical totals in the 13 to 18 mill range. A handful of service areas with heavy road or fire costs push higher.
Matanuska-Susitna Borough
Mat-Su has the lowest base rates among the major boroughs. The areawide rate for the fiscal year 2026 budget is 8.485 mills, with a non-areawide levy of 0.371 mills.6Matanuska-Susitna Borough. Your Mat-Su Borough Tax Bill Once road, fire, and other service area levies are added, most homeowners land somewhere between 9 and 13 mills total. Rapid population growth has kept assessed values climbing, which lets the borough hold mill rates lower while collecting the revenue it needs.
The Unorganized Borough
Large parts of Alaska sit within the unorganized borough, which has no municipal government and no authority to levy property tax.3Alaska Department of Commerce, Community, and Economic Development. Property Tax – Local Government Online A cabin or homestead outside any organized borough or city owes zero property tax. The tradeoff is minimal public services: no borough-funded road maintenance, no local fire department, no publicly funded trash collection.
Exemptions That Cut the Bill
Alaska law requires every municipality to exempt the first $150,000 of assessed value on the primary residence of qualifying homeowners. Three groups are eligible under AS 29.45.030(e):7Justia. Alaska Code 29.45.030 – Required Exemptions
- Senior citizens aged 65 or older.
- Disabled veterans with a service-connected disability rating of 50 percent or more.8Department of Commerce, Community, and Economic Development. Property Tax Exemptions in Alaska
- Surviving spouses aged 60 or older whose deceased spouse qualified under either of the first two categories.
At a 15-mill rate, this exemption saves a qualifying homeowner $2,250 a year. On a $400,000 home, taxes apply only to the remaining $250,000. Municipalities can also grant hardship exemptions above the $150,000 floor under state regulations.7Justia. Alaska Code 29.45.030 – Required Exemptions
You have to apply through your local assessor’s office by the deadline your municipality sets. In many boroughs that deadline falls on or around January 15 of the assessment year.9City of Craig. 2025 City of Craig Senior Citizen/Disabled Veteran Property Tax Exemption Application Filing late does not automatically disqualify you, but it adds paperwork. Only one exemption applies per property, so co-owners who both qualify pick which one claims it.
If Your Assessed Value Looks Wrong
Assessors use mass appraisal methods, drawing on recent sales of similar properties, rebuild-cost estimates, or income data for rental and commercial buildings. Values update periodically to reflect the market, and a rising market can push your tax bill up even when the mill rate holds flat.
Under AS 29.45.190, you have 30 days from the date the assessment notice is mailed to file a written appeal with the borough assessor stating the grounds for your objection.10Justia. Alaska Code 29.45.190 – Appeal Miss that window and your appeal rights expire for the year unless the board of equalization finds you were unable to comply.
The strongest grounds are that the assessed value is higher than market value, that comparable properties are assessed lower, or that the assessor used incorrect data on square footage or lot size. Show up with two or three comparable sales that closed near the assessment date at prices below your assessed value. The board decides value, not tax bills, so general frustration about a high bill does not move it.
Payment Deadlines and Penalties
Payment schedules vary, but most boroughs let you split the annual bill into two installments. In Anchorage, the first installment for real property is due June 30 and the second is due August 31.11Municipality of Anchorage. Dates for Property Taxation Mat-Su bills on July 1, with installment options. Other boroughs set their own dates.
Under AS 29.45.250, municipalities can charge a penalty of up to 20 percent on delinquent tax, plus interest of up to 15 percent per year running from the original due date until paid.12Justia. Alaska Code 29.45.250 – Rates of Penalty and Interest Each borough sets its own structure within those caps, and some ratchet the penalty higher the longer the balance stays unpaid. On a $4,000 bill, a 20 percent penalty plus a year of interest at 15 percent adds $1,400.
What Happens If Taxes Go Unpaid
Long-delinquent property taxes in Alaska can lead to foreclosure. Once foreclosure is complete, the borough can sell the property at a tax sale to recover unpaid taxes, penalties, interest, and collection costs.13Justia. Alaska Code 29.45.480 – Proceeds of Tax Sale If the sale price exceeds what you owed, you are entitled to the surplus, but only if you file a claim within six months of the sale date. After that, the right to any excess is permanently lost.
The specific timeline between initial delinquency and foreclosure varies by borough. If you fall behind, call your local tax office. Most municipalities will set up a payment arrangement rather than absorb the cost of foreclosing.
