Lehigh County Property Tax Appeal: Your 2026 Guide
TL;DR
The effective property tax rate in Lehigh County, Pennsylvania is roughly 2.10%. Properties are assessed based on values from the county's most recent reassessment (2013). The Common Level Ratio (CLR) adjusts for market changes between reassessments. File your appeal by August 1 (for the following tax year) with the Lehigh County Board of Assessment Appeals. Filing fee is typically $25-$50. Pennsylvania has some of the highest property taxes in the country, making appeals especially worthwhile.
Part of the Lehigh Valley in eastern Pennsylvania. Allentown is the largest city. A mix of urban, suburban, and rural properties with values that have risen significantly since the last reassessment. The median home value is around $280,000, with a typical annual property tax bill near $5,880. Pennsylvania's property tax system is uniquely complex. Counties rarely reassess, creating large gaps between assessed values and actual market values. The state addresses this with the Common Level Ratio, but the system is imperfect and overassessments are common.
If you think your property taxes are too high, you may be right. The appeal process is your tool to fix it, and you do not need a lawyer to use it.
How Lehigh County Assessments Work
Lehigh County last reassessed all properties in 2013. Those base-year values remain on the books until the county does another countywide reassessment. Since market values have changed since 2013, the state publishes a Common Level Ratio (CLR) each year that reflects the relationship between assessed values and current market values.
Understanding the Common Level Ratio
The CLR is the key to Pennsylvania property tax appeals. Here is how it works with an example:
Suppose the current CLR for Lehigh County is 70%. That means, on average, assessed values in the county are 70% of current market values. If your home would sell for $300,000 today, a "fair" assessed value under the current CLR would be $300,000 x 0.70 = $210,000. If your assessed value is $230,000, you are over-assessed by $20,000 and likely overpaying.
| Concept | Explanation |
|---|---|
| Base Year Assessed Value | Value set during 2013 reassessment |
| Common Level Ratio (CLR) | State-published ratio reflecting assessed-to-market relationship |
| Current Market Value | What your home would sell for today |
| The Test | If (Market Value x CLR) is less than your assessed value, you may be over-assessed |
| Step | Example ($280,000 home) |
|---|---|
| Current Market Value | $280,000 |
| Assessed Value (from 2013) | Varies by property |
| Combined Tax Rate (county + school + municipal) | ~2.10% effective |
| Annual Tax Bill | ~$5,880 |
Check the current CLR on the State Tax Equalization Board (STEB) website before filing your appeal. The ratio changes every year and is published in the Pennsylvania Bulletin each July.
Why Pennsylvania's System Creates Overassessments
Because Lehigh County has not reassessed since 2013, all properties carry values from that year. But market values have not moved uniformly since then. Some neighborhoods appreciated faster than others. Some property types gained more than others. The CLR is a single countywide ratio that cannot account for these differences. This means individual properties can be significantly over- or under-assessed even when the countywide average looks correct.
Exemptions Available in Lehigh County
Before appealing the assessed value, confirm you are receiving every exemption you qualify for.
| Exemption | Benefit |
|---|---|
| Homestead Exclusion | Reduction in assessed value for primary residence (funded by gaming revenue) |
| Senior Citizen Tax Rebate | State rebate program for qualifying seniors |
| Disabled Veteran | Exemption for qualifying disabled veterans |
| Clean and Green | Preferential assessment for agricultural/forest/open space land |
Apply for exemptions through the Lehigh County Assessment Office. The Homestead Exclusion is funded by gaming revenue and automatically reduces your school tax assessment if you have applied and been approved. If you have not applied, you are leaving money on the table.
Step-by-Step: How to Appeal in Lehigh County
Step 1: Look Up Your Assessment
Find your property's assessed value on the Lehigh County Assessment Office website (lehighcounty.org). Note the assessed value, the property description, and any exemptions. Compare the assessed value to your home's current market value multiplied by the CLR. If your assessed value exceeds that product, you may have grounds for an appeal.
Step 2: Gather Your Evidence
Build your case before filing. The strongest evidence includes:
- Comparable sales: Recent sales of similar properties that support your claimed market value. This is the most effective and most commonly used evidence. Find 3-5 sales within a mile, similar in size and age, sold within the past 12 months.
- Recent professional appraisal: If you had an appraisal done for a refinance, purchase, or other reason that shows a lower market value, this carries significant weight.
- Property condition documentation: Photos and contractor estimates for needed repairs, structural issues, outdated systems, or other factors that reduce value.
- Data errors in assessment records: Wrong square footage, incorrect room count, wrong lot size, overstated condition, or other mistakes. Pull your property record card from the county website and check every field.
- CLR calculation: Show the Board explicitly how your current market value times the CLR compares to your assessed value. Make the math clear and easy to follow.
Step 3: File Your Appeal
File an appeal with the Lehigh County Board of Assessment Appeals by August 1 (for the following tax year). The filing fee is typically $25-$50 per parcel. You can file in person, by mail, or in some cases online through lehighcounty.org. On the form, state the current market value you believe is correct and briefly describe why.
Step 4: Attend Your Hearing
The Board holds hearings throughout the year. You will receive a hearing date after filing. The hearing typically lasts 15-20 minutes for residential properties. Present your evidence clearly. Bring printed copies for each Board member and the county's representative (usually four sets).
Walk the Board through your comparable sales, show the CLR calculation, and present any condition or data error evidence. Be concise, factual, and respectful. The Board issues a decision, usually within a few weeks.
Step 5: Further Appeals (If Needed)
If you disagree with the Board's decision, you can appeal to the Court of Common Pleas. This is a more formal legal proceeding and some homeowners retain an attorney at this stage. However, most residential appeals are resolved at the Board level.
Evidence Tips for Lehigh County
The most successful appeals in Pennsylvania present a clear, data-driven case. Avoid emotional arguments. Focus on numbers.
| Property | Sq Ft | Year Built | Sale Price | $/Sq Ft |
|---|---|---|---|---|
| Your Home | 1,800 | 1995 | $280,000 (est. market) | Varies |
| Comp 1 (Sold) | 1,750 | 1993 | Lower | Lower |
| Comp 2 (Sold) | 1,850 | 1996 | Lower | Lower |
| Comp 3 (Sold) | 1,800 | 1994 | Lower | Lower |
| Comp 4 (Sold) | 1,900 | 1997 | Lower | Lower |
Present both the market value evidence (comparable sales) AND the CLR calculation. The Board needs to see: (1) what your home is actually worth, and (2) how that translates to a fair assessed value under the current ratio. Make both steps explicit.
Common Mistakes to Avoid
- Missing the filing deadline. August 1 (for the following tax year) is the cutoff. No late filings are accepted.
- Ignoring the CLR. You cannot simply compare your assessed value to market value directly. The CLR adjustment is essential. Without it, your argument will not make sense to the Board.
- Using the wrong CLR. The CLR changes every year. Make sure you are using the most current published ratio, not last year's number.
- Arguing about tax rates or spending. The Board controls the assessed value only. Tax rates are set by school districts, municipalities, and the county. Complaining about rates wastes your hearing time.
- Using Zillow or online estimates as evidence. Use actual recorded sales from county deed records or MLS data. Algorithm estimates are not accepted.
- Not checking for the Homestead Exclusion. If you have not applied for this exemption, you may be missing a significant school tax reduction that costs you nothing to claim.
