How Property Tax Works

Kodiak Island Borough levies property taxes to fund essential local services including schools, emergency services, infrastructure maintenance, and general government operations. The borough operates under Alaska state law, which allows municipalities to set their own property tax rates and assessment practices. Property taxes in Kodiak Island Borough are assessed on both real property (land and buildings) and personal property, with taxes calculated based on the assessed value of your property multiplied by the applicable tax rate.

The effective tax rate in Kodiak Island Borough varies depending on your location within the borough due to different special taxing districts and municipal boundaries. Some areas may be subject to additional assessments for school districts, fire protection, or other special services. The City of Kodiak, for example, levies an additional 2 mil tax on properties within city limits. Property owners should verify their specific tax rate based on their property's location and applicable taxing jurisdictions.

Supplemental Tax Bills

Supplemental taxes in Alaska are governed by state law (AS 29.45.010 - .600) and may be levied when property assessments change mid-year due to new construction, improvements, or ownership transfers. When supplemental taxes are assessed, they are calculated on a pro-rated basis from the date the change occurred through the end of the tax year. For example, if you complete a home addition in March, you may receive a supplemental tax bill covering the increased assessed value from March through the end of the fiscal year.

The supplemental tax amount is calculated by taking the difference between your new assessed value and previous assessed value, multiplying by the applicable tax rate, then pro-rating for the remaining months in the tax year. Under AS 29.45.090, property is taxed at the same rate throughout the municipality for the entire year, ensuring consistency in tax calculations.

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts for Kodiak Island Borough properties, collecting monthly payments along with your mortgage payment to ensure taxes are paid on time. Your lender will analyze your previous year's tax bill and estimate the coming year's taxes, dividing by 12 for your monthly escrow payment. Lenders typically maintain a cushion of 2-6 months of tax payments in your escrow account to cover potential increases.

The escrow payment timing aligns with Kodiak Island Borough's split payment schedule. For taxes over $50, payments can be made in two installments: the first half due August 15th and the second half due November 15th. Your lender will typically make these payments on your behalf. If the first half payment is missed, the full amount must be paid by October 15th to avoid penalties. You should receive an annual escrow analysis from your lender showing how your payments were applied and any adjustments needed for the coming year.
