How Property Tax Works

Northampton County, Pennsylvania operates under a property tax system that funds essential local services including schools, municipal operations, and county government functions. Property owners pay taxes based on their property's assessed value, which is multiplied by the applicable tax rate (millage). The county conducts periodic reassessments to ensure fair market valuations across all properties.

Property tax rates in Northampton County vary significantly by location due to overlapping taxing jurisdictions. Property owners typically pay taxes to multiple entities: the county, their local municipality (borough or township), and their school district. Additional special district assessments may apply for services like fire protection, library services, or municipal authorities. The combined effective tax rate generally ranges from approximately 1.5% to 2.5% of assessed value, depending on the specific taxing districts where the property is located.

It's important to note that most property tax credits and relief programs require annual applications and are not automatically applied to tax bills. Property owners should verify their specific tax obligations and available relief programs through the Northampton County Department of Revenue and their local tax collector.

Section 4

Supplemental Tax Bills

Supplemental property taxes in Northampton County are additional tax assessments that occur when there are changes to a property's ownership, use, or value during the tax year. The most common triggers include new construction completion, property improvements that increase assessed value, changes in property use (such as commercial to residential), or corrections to assessment errors discovered mid-year.

When a supplemental assessment is issued, the additional tax is calculated by applying the current tax rate to the increase in assessed value, prorated for the remaining months in the tax year. For example, if a $50,000 home addition is completed in July (6 months remaining in the tax year), and the combined tax rate is 30 mills, the supplemental tax would be calculated as: ($50,000 ÷ 1,000) × 30 mills × (6 months ÷ 12 months) = $750.

Property owners typically receive supplemental tax bills within 30-60 days after the triggering event. These bills are separate from regular annual tax bills and have their own payment due dates. The supplemental tax becomes part of the property's ongoing annual assessment for subsequent tax years, so future regular tax bills will reflect the higher assessed value.

Escrow & Property Taxes

Most mortgage lenders in Northampton County require borrowers to establish an escrow account for property tax payments, especially when the loan-to-value ratio exceeds 80%. The lender collects monthly escrow payments along with principal and interest, then pays property taxes directly to the appropriate tax collectors on behalf of the homeowner.

Property tax payments in Northampton County are typically due by April 1st for the current tax year, with a grace period extending to May 31st if mailed. Lenders usually make payments during the discount period to minimize escrow account requirements. The escrow account is analyzed annually, and lenders must provide borrowers with an escrow analysis statement showing the account activity, projected payments, and any required payment adjustments.

Homeowners with escrowed taxes should verify that payments are made correctly and on time by reviewing their annual tax statements and escrow analysis. If tax rates increase significantly or if supplemental assessments are issued, the escrow payment may need to be adjusted. Property owners can contact their lender's escrow department to request payment verification and ensure adequate funds are maintained to avoid tax delinquencies that could result in penalties or tax liens.
