Those who have contested their new Warren County property assessments will receive notice whether their appeal was upheld or denied this week.

Decision notices to the nearly 2,750 Warren County property owners who appealed their property valuation as part of Warren County’s property reassessment will be mailed this week, dated Nov. 12.

Chief Assessor Brian Bull said that “Clean and Green” program letters will also be sent at the same time. The Pennsylvania Clean and Green program is a preferential tax assessment program that allows qualifying agricultural, forest, and open space landowners to have their property taxed based on its current use value, not its fair market value. This can result in lower property taxes by basing the assessment on the land’s use value rather than its development potential. To qualify, a property must generally be at least 10 acres, although smaller parcels can qualify if they generate at least $2,000 in annual agricultural income.

A total of 2,741 appeals were held this summer as part of the reassessment process. With the appeal process complete, the next major task is the certificate of values for all parcels, which must be completed

by Nov. 15. That data is then sent to the county’s taxing bodies to be incorporated as part of the 2026 budget process.

Unlike past notices sent as part of this process that went to all property owners, Deputy Chief Assessor Beth Schmader pointed out that only people that filed appeals will receive notices this week. Bull encouraged those who don’t receive their notice in two to three weeks to reach out to the county Assessment Office. That’s because appellants have 30 days from the date on the decision notice – Nov. 12 – to file with the Court of Common Pleas should they wish to challenge the appeal board’s decision.

Assessment staff are unable to provide legal counsel or directions on how to file that challenge. Those looking to do so are encouraged to contact an attorney.

Sending the decision notices this week brings the county’s reassessment process, its first property reassessment since

1989, to a close. The project began in the spring of 2023, with properties being valued as of January 1, 2025. Those new values become effective levying property taxes starting on Jan. 1, 2026.
