County property taxes in Bucks, Delaware and Montgomery counties will increase in 2026, but Chester County taxes will stay level. Property tax rates are measured in millage, with one mill being worth $1 for every $1,000 of assessed property value.

• Bucks County commissioners voted 2-1 to adopt a roughly $517 million budget for 2026 that includes a 2.2-mill property tax increase. The 8% millage rate increase — from the current 27.45 to 29.65 mills — will close an operational budget deficit of more than $16 million, while adding an extra $72 annually to an average property owner’s tax bill.
• Chester County commissioners approved a $778.6 million county budget for fiscal year 2026 that holds the real estate tax rate steady. The overall property tax rate for 2026 remains 5.164 mills.
• Delaware County Council unanimously approved a $418.5 million 2026 budget with a 19% property tax increase. There will be a general tax levy of 4.008 mills and a debt service levy of 0.601 mills on assessed property, for a total of 4.609 mills. A property owner with the average assessed value of $255,472 will see their county taxes increase by $188.
• Montgomery County Board of Commissioners unanimously approved its 2026 budget. The county is raising property taxes by 4% to generate about $12 million in additional revenue for its general fund. The increase will equate to roughly $36 more in property taxes next year for the average single-family dwelling. The budget includes 5.462 mills for county operations and 0.49 mills for Montgomery County Community College, for a total of 5.952 mills.
