Deadline and where to file
New Castle values are set by the local county assessment office. Under state law the annual appeal deadline is September 1, unless the county commissioners choose an earlier date no sooner than August 1 (many counties use August 1). If your assessment changes mid-year, you have 40 days from the date of the notice. Philadelphia is different: the Board of Revision of Taxes deadline is the first Monday in October of the year before the tax year.
Reading this in fall 2026? If you live in Philadelphia, the deadline for 2027 values is Monday, October 5, 2026, which is the day after today, so file immediately with the Board of Revision of Taxes. Everywhere else in Pennsylvania the 2026 annual deadline (August 1 or September 1) has passed. Your next regular chance is August 1 or September 1, 2027 (check your county's date), unless you get a change-of-assessment notice, which gives you 40 days to appeal.

Building a New Castle case
The numbers above describe the typical New Castle home, not yours. New Castle is part of the New Castle metro, but your evidence should be local. Sales a few streets away usually beat sales across the metro.
- Pennsylvania courts apply the State Tax Equalization Board's common level ratio to market value, so find your county's ratio and compare your assessment to market value times that ratio.
