How Property Tax Works

Dauphin County, Pennsylvania operates on a property tax system that funds essential local services including schools, municipal operations, and county government functions. Property taxes in Dauphin County are calculated using a millage rate system, where rates are expressed in mills (1 mill = $1 per $1,000 of assessed value). The county's property tax burden varies significantly by location within the county due to different municipal and school district rates, with effective rates typically ranging from approximately 2% to 3% of assessed value annually.

Property assessments in Dauphin County are conducted by the county assessment office, and unlike some Pennsylvania counties, there is no assessment cap limiting annual increases in assessed value. The tax year runs on a calendar basis, with the 2025 millage rates set to be announced in January 2025 by the Board of Commissioners. Taxpayers benefit from early payment discounts if taxes are paid by March 31st, while delinquent taxes incur additional fees and penalties.

Supplemental Tax Bills

Supplemental property taxes in Dauphin County are additional tax assessments that occur when there are changes to a property's ownership, use, or physical characteristics after the regular assessment period. Common triggers include new construction, major renovations that increase property value, subdivision of land, or changes in property classification (such as converting from residential to commercial use).

Supplemental taxes are calculated by determining the difference between the old assessed value and the new assessed value, then applying the current millage rate to that difference. The supplemental tax is prorated based on the number of months remaining in the tax year from the date the change became effective. For example, if a $50,000 addition is completed in July and increases the assessed value by that amount, the supplemental tax would apply to 6 months of that tax year at the applicable millage rate.

Escrow & Property Taxes

Most mortgage lenders in Dauphin County require property tax escrow accounts for borrowers with less than 20% down payment. Your lender collects monthly property tax payments along with your mortgage payment and holds these funds in an escrow account. The lender then pays your property taxes directly to Dauphin County when they become due, typically by the March 31st early payment deadline to secure available discounts.

Lenders are required to perform annual escrow analyses to ensure adequate funds are collected. If property taxes increase due to reassessment or rate changes, your monthly escrow payment may increase accordingly. You should receive an annual escrow statement showing all deposits and payments made on your behalf. It's important to verify that your lender is taking advantage of early payment discounts, as this can result in significant savings over time. If you pay taxes independently, remember that delinquent taxes beginning February 3rd of the following year incur a $20 fee per tax due, plus additional penalties and interest.
