How Property Tax Works

Petersburg County (Petersburg Borough), Alaska operates under a property tax system that funds essential local services including schools, public safety, infrastructure maintenance, and municipal operations. Property taxes are calculated based on the assessed value of real property, with assessments conducted annually to reflect current market conditions. The borough's property tax system serves as a primary revenue source for local government operations and community services.

Property tax rates in Petersburg County vary by location within the borough due to special taxing districts and service areas that may impose additional assessments beyond the base borough levy. Property owners should verify their specific tax rate based on their property's location and applicable service districts. The borough provides online resources for property tax information and payment processing, available 24 hours a day through the Property Tax Division.

Supplemental Tax Bills

Supplemental taxes in Petersburg County are typically assessed when there are changes in property ownership, new construction, or significant improvements that alter the property's assessed value during the tax year. These supplemental assessments ensure that property taxes reflect current ownership and property conditions rather than waiting for the next regular assessment cycle.

When a supplemental tax is triggered, it is calculated based on the difference between the previous assessed value and the new assessed value, prorated for the portion of the tax year remaining. For example, if a property undergoes major improvements worth $50,000 in assessed value halfway through the tax year, the supplemental tax would be calculated on that $50,000 increase for the remaining six months of the tax year at the applicable tax rate.

Escrow & Property Taxes

Most mortgage lenders in Petersburg County require property tax escrow accounts for borrowers with less than 20% down payment. The lender collects monthly escrow payments along with principal and interest, holding these funds to pay property taxes when due. Escrow payments are calculated by dividing the annual property tax bill by 12 months, often with an additional cushion to account for potential tax increases.

Property owners with escrow accounts should verify that their lender receives and pays tax bills correctly. The Petersburg Borough Property Tax Division sends tax bills to both the property owner and the mortgage company when an escrow account is established. Property owners remain ultimately responsible for ensuring taxes are paid on time, even when using escrow services. Annual escrow account statements show how funds were collected and disbursed throughout the year.
