How Property Tax Works

Fairbanks North Star Borough (FNSB) operates on a property tax system that serves as the primary funding mechanism for essential local services including schools, public safety, road maintenance, and borough operations. Property taxes in FNSB are calculated based on the assessed value of real property, which is determined annually by the Borough Assessor's Office. The borough maintains full market value assessments with no assessment caps, meaning property values can increase to full market levels each year.

Property tax rates in Fairbanks North Star Borough vary significantly depending on your location within the borough due to special taxing districts and service areas. The effective tax rate typically ranges from approximately 1.2% to 2.5% of assessed value, depending on which combination of areawide, non-areawide, service areas, and special districts apply to your property. Rural properties may have lower rates while properties in incorporated cities or special service areas may face higher combined rates due to additional levies for enhanced services.

When Are Property Taxes Due?

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.

Supplemental Tax Bills

Supplemental taxes in Fairbanks North Star Borough are additional property tax assessments that occur when there are changes to property ownership, new construction completion, or significant improvements made after the annual assessment date (typically January 1). These supplemental bills ensure that property tax obligations are properly allocated between buyers and sellers during ownership transfers, and that new construction or improvements are taxed for the portion of the tax year they were completed.

When property changes hands, the supplemental tax is calculated based on the difference between the previous assessment and the new assessed value, prorated for the remaining months in the tax year. For example, if a $400,000 home sells in July for $500,000, and the borough reassesses it at the sale price, a supplemental tax would be calculated on the $100,000 increase for the remaining 6 months of the fiscal year. At a combined tax rate of $14.00 per $1,000, this would result in a supplemental bill of approximately $700 ($100,000 ÷ 1,000 × $14.00 × 6/12 months).

Escrow & Property Taxes

Most mortgage lenders in Fairbanks North Star Borough require property tax escrow accounts, where monthly payments are collected along with your mortgage payment and held until tax bills are due. The borough's fiscal year runs from July 1 to June 30, with tax bills typically mailed in late July or early August. Escrow accounts must maintain adequate reserves to cover the full annual tax obligation, and lenders typically require a cushion of 2-3 months of payments.

Property tax payments from escrow are generally made by lenders in two installments if the full amount exceeds $500: the first half is due October 31 and the second half is due March 31. For payments under $500, the full amount is due October 31. Homeowners should verify their escrow analysis annually to ensure adequate funding, especially after reassessments or rate changes. If you pay taxes directly rather than through escrow, you can make payments online, by mail, or in person through the Borough Treasury Department at https://www.fnsb.gov/166/Treasury.

Frequently Asked Questions

Q: When are property taxes due for FY 2025-2026? A: Tax bills are typically mailed in late July 2025. First half payment is due October 31, 2025, and second half is due March 31, 2026. If the total tax is under $500, the full amount is due October 31, 2025.

Q: What tax credits are available and do I need to apply? A: FNSB offers several tax credits including Senior Citizen ($150,000 assessment reduction), Veterans' Disability ($150,000 reduction), and Homestead (10% annual assessment increase cap). ALL credits require annual application by March 31 preceding the tax year - they are NOT automatic.

Q: How does the Homestead credit work? A: The Homestead credit limits annual assessment increases to 10% for owner-occupied primary residences. It does NOT reduce market value but caps how much your assessment can grow each year. You must apply annually by March 31 and occupy the property as your primary residence.

Q: When are properties assessed and how can I appeal? A: Properties are assessed annually as of January 1. Assessment notices are mailed in spring. You have 30 days from the mailing date to file an appeal with the Board of Equalization. Contact the Assessor's Office at https://www.fnsb.gov/160/Assessing for appeal forms and procedures.

Q: What are the penalties for late payment? A: Interest accrues at 12% annually on unpaid taxes starting November 1 for first half payments and April 1 for second half payments. Additional penalties may apply for severely delinquent accounts.

Q: Can I pay my taxes online? A: Yes, online payments are available through the Borough Treasury website at https://www.fnsb.gov/166/Treasury. You can pay by electronic check or credit card, though credit card payments may include processing fees.

Q: Why do tax rates vary across the borough? A: Different areas receive different levels of services through special taxing districts. Rural areas may only pay areawide levies, while properties in service areas pay additional rates for fire protection, water/sewer, or enhanced services.

Q: Do I still pay borough taxes if I live in the City of Fairbanks or North Pole? A: Yes, but you pay city taxes instead of the borough's non-areawide levy. You still pay borough areawide taxes, school taxes, and any applicable service area taxes, plus your respective city taxes.
