What your assessed value means here

Pennsylvania — assessed at a base-year value; the STEB Common Level Ratio for your county is about 43.67% of current market. Confirm the ratio on your notice (53 Pa.C.S. §8854).

Lycoming County's common level ratio is drawn from the 2025 CLR (2024 sales data; effective 7/1/2026–6/30/2027) table — the same figure the app uses to compare your assessment to current market value.

Can the board raise your assessment?

Yes. The Lycoming County Board of Assessment Appeals can raise your assessment on your own appeal, not only lower it. That is the risk you take by filing, and it is why the case has to be worth making before you file it.

What a board actually weighs

The Lycoming County Board of Assessment Appeals decides what your property was worth on the valuation date, so recent comparable sales carry the case, not the size of the bill. The Pennsylvania guide covers the evidence.
