Supplemental Tax Bills

Supplemental tax bills are issued when property ownership changes or when new construction is completed during the tax year. These taxes cover the period from when the change occurred through the end of the current tax year. For example, if you purchase a property in March, you may receive a supplemental bill covering March through December.

The supplemental tax is calculated by taking the difference between the previous assessment and the new assessment, then applying the current tax rate for the remaining months of the tax year. Property owners have the right to request exoneration of supplemental tax bills under certain circumstances, as evidenced by historical requests for 2018 and 2023 county supplemental real estate tax bill exonerations in Mifflin County.

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts for borrowers with less than 20% down payment. The lender collects monthly escrow payments along with your mortgage payment and pays property taxes directly to the county on your behalf. Lenders typically collect 1/12th of your annual tax bill each month, plus a cushion amount as allowed by federal law.

Property tax bills in Mifflin County are due by December 31st of each tax year. Lenders usually pay during the discount period (ending October 3rd) to take advantage of reduced payment amounts. Property owners should verify that their lender has made timely payments and review their annual escrow analysis to ensure adequate funds are being collected for the following year's taxes.
