Supplemental Tax Bills

Supplemental property taxes in Strafford County are additional tax bills issued when there are changes to property ownership, value, or use that occur after the annual assessment date but before the end of the tax year. Common triggers include new construction completion, property transfers with reassessment, additions or improvements that increase property value, or changes in property use classification (such as residential to commercial).

Supplemental taxes are calculated by taking the difference between the new assessed value and the original assessed value, then applying the current tax rate for the remaining months in the tax year. For example, if a $100,000 addition is completed in January and assessed in March, the supplemental tax would be calculated as: ($100,000 × $20.96/$1,000) × (4 months remaining/12 months) = $698.67. The supplemental bill is typically issued within 30-60 days of the triggering event and has its own due date, usually 30 days from the bill date.

Escrow & Property Taxes

Most mortgage lenders in Strafford County require borrowers to maintain an escrow account for property tax payments, particularly for loans with less than 20% down payment. Lenders collect monthly escrow payments equal to the annual property tax divided by 12, plus a small cushion typically ranging from 2-3 months of payments. The lender pays property taxes directly to the municipal tax collector when bills are due, usually in July of each tax year.

Property owners should verify that their lender has the correct tax amount, as escrow shortages can occur when property values increase significantly or tax rates change. Lenders typically conduct annual escrow analyses and may adjust monthly payments to account for changes in tax obligations. If you pay taxes independently without escrow, you're responsible for ensuring timely payment to avoid interest charges and potential tax lien procedures. Contact your municipality's tax collector office to confirm payment receipt and maintain records of all tax payments.
