Are Pennsylvania property taxes paid in advance?

In Pennsylvania, property taxes are typically paid in arrears, meaning they are assessed for a previous year and paid in the current year. Property taxes are usually based on the assessed value of the property as of January 1 of the tax year, and payments are due in installments or as a lump sum, depending on the municipality's schedule. However, specific payment structures can vary by locality, so it's essential to check with the local tax authority for details.
