Property Taxes in Allentown
Lehigh County property taxes are shaped by a genuinely distinctive mechanic: the county last conducted a countywide reassessment in 2013, and assessed values have remained frozen at that year's levels ever since (current Common Level Ratio approximately 47%), producing a real, wide, disclosed spread in cited effective property tax rates across sources reviewed this pass -- approximately 1.48% per one source versus approximately 2.87% per another -- both meaningfully above the national average.

Unlike states with a uniform annual or short-cycle reassessment schedule, Lehigh County last conducted a countywide property reassessment in 2013 -- assessed values have remained frozen at that year's market levels ever since, even as actual market values have risen substantially. Pennsylvania's state-set Common Level Ratio (CLR), currently approximately 47% for Lehigh County, is used to translate those frozen 2013-base-year assessed values back toward current market value for certain purposes, including the state's realty transfer tax. Buyers and current owners alike should understand this mechanic precisely before comparing an Allentown-area tax bill to one in a state with more frequent reassessment.
A Real, Wide, Disclosed Spread in Cited Effective Rates, Likely Tied to This Mechanic
This record found a genuinely wide, disclosed spread across sources reviewed this pass: one source cited Lehigh County's effective property tax rate at approximately 1.48% (median $3,004/year on a median home value of approximately $203,200, ranking Lehigh County 8th among Pennsylvania's 67 counties by median tax paid), while a separate aggregator (Ownwell) cited a notably higher 'median effective rate' of approximately 2.87%. This record attributes the spread to the county's 2013-base-year assessment mechanic and differing aggregator methodologies for handling it, rather than silently resolving to one figure.
Both Cited Rates Run Meaningfully Above the National Average, and Pennsylvania Statewide Also Runs High
Even at the lower end of the disclosed spread (~1.48%), Lehigh County's effective property tax rate runs meaningfully above the roughly 0.92% national average. Pennsylvania statewide carries its own real, disclosed spread across sources (approximately 1.26%-1.35% effective rate), ranking the state approximately 12th-16th highest nationally depending on source -- both figures meaningfully above the national average, consistent with the broader Northeast property-tax pattern.
Confirm the Actual Bill for a Specific Property
Given the real complexity introduced by Lehigh County's 2013-base-year assessment system and the resulting CLR adjustment, confirm the actual current assessed value, applicable millage, and resulting tax bill for a specific Allentown-area property directly with the Lehigh County Assessment Office rather than relying on any single citywide or countywide percentage figure in this file.
Millage Combines Multiple Overlapping Taxing Districts
As with most Pennsylvania municipalities, a property's total property tax bill combines separate millage rates from the county, the municipality (City of Allentown), and the relevant school district (commonly Allentown School District, though some Allentown-area addresses may fall within a different district) -- confirm the actual current combined millage for a specific address directly.
Key takeaways
- Lehigh County last reassessed properties countywide in 2013 -- assessed values remain frozen at that year's levels, with a current Common Level Ratio of approximately 47% used to adjust toward current market value for certain purposes.
- This record found a real, wide, disclosed spread in cited effective property tax rates across sources (~1.48% vs. ~2.87%), likely tied to this base-year assessment mechanic and differing aggregator methodologies.
- Both cited rates run meaningfully above the ~0.92% national average; Pennsylvania statewide also runs high (~1.26%-1.35%, ranked ~12th-16th nationally).
- Confirm the actual current assessed value, millage, and resulting tax bill for a specific Allentown-area property directly with the Lehigh County Assessment Office.
- A property's total bill combines county, municipal, and school-district millage -- confirm the actual current combined rate for a specific address directly.
