Are you seeing a list price that looks nothing like the tax assessment and wondering which number actually matters? You are not alone. If you are buying or selling in Harrison City, the difference between assessed value and market value can be confusing, and it affects both your pricing strategy and your property tax bill. In this guide, you will learn what each value means, how Westmoreland County sets assessments, how the Pennsylvania homestead/farmstead exclusion works, and how to estimate taxes with simple math. Let’s dive in.
Assessed vs. market value: the basics
Market value is the probable price a property would sell for under normal conditions. It is shaped by current supply and demand, recent comparable sales, your home’s condition, and what buyers are willing to pay.
Assessed value is what Westmoreland County assigns for tax purposes. The county uses mass appraisal to value many properties at once, and that number becomes the base for local property taxes.
The key difference is simple: pricing and negotiations follow market value, while your tax bill is based on assessed value, after any eligible exclusions and the local millage rate. A sale price does not automatically become your assessed value.
How Westmoreland County assessments work
Mass appraisal in practice
The Westmoreland County Assessment Office sets assessed values using mass appraisal models. These models consider property data like square footage, beds and baths, age, condition, and location, and they factor in area sales as data points. Some properties, such as new builds or homes with recent permits, may get additional review.
Reassessments and timing
Counties perform county-wide reassessments periodically to realign assessments with the market. If values have climbed since the last reassessment, your assessed value may lag behind current market value. If the market cooled since the last reset, the opposite can happen.
Notices and appeals
When values change or during a reassessment year, owners receive a notice with the new assessed value and instructions to appeal. If you believe your assessment is inaccurate, you can:
- Review the notice and property data for errors.
- Request an informal review with the assessor to correct mistakes.
- File a formal appeal with the county’s Board of Assessment Appeals, supplying evidence such as comparable sales, a recent appraisal, photos, or documentation of incorrect characteristics.
- If needed, pursue further appeal through state channels.
Keep good records and recent comps. If your square footage is wrong or updates were missed, bring that documentation to the county.
Do sales reset assessed values?
Individual sales help inform the county’s models, but a single sale does not instantly change your assessment. Updates come through reassessments or administrative changes across the roll.
Pennsylvania’s homestead/farmstead exclusion
The homestead/farmstead exclusion can reduce the school portion of your property taxes for an eligible owner-occupied residence. To qualify, the home must be your primary residence and you must file a homestead application with the county. Life events like a move, marriage, or ownership change can affect eligibility, so update your status as needed.
How it works:
- The county sets a uniform exclusion amount for each school district.
- For qualifying homes, that exclusion amount is subtracted from the assessed value used to calculate school taxes.
- The exclusion usually applies to school taxes only. County and municipal taxes are typically calculated on the full assessed value unless local rules say otherwise.
In Harrison City, this program can materially lower the school tax line for owner-occupants. The exact dollar savings depend on the current exclusion amount and your school district’s millage.
What this means for your Harrison City move
For sellers: price based on market value, not the assessment. Assessed values often lag the market, so your list price and expected proceeds should follow recent comps. Share your current assessed value and any homestead status with buyers so they can estimate taxes accurately.
For buyers: do not assume your taxes will jump to match your purchase price right away. Your tax bill starts with the current assessed value on the county roll, adjusted by any homestead exclusion you apply for as an owner-occupant, then multiplied by the latest millage rates. Future reassessments may change that number, so budget with a range.
Quick examples and tax math
Below are illustrative scenarios to show how assessed value, the homestead exclusion, and millage come together. Always verify your property’s assessed value, current exclusion amount, and the latest millage rates before you finalize a budget.
Remember: 1 mill equals $1 of tax per $1,000 of assessed value.
| Property type | Market value (expected sale price) | County assessed value (current) | Homestead exclusion (if eligible) | Taxable assessed value (assessed − exclusion) | Example combined school millage (mills) | Estimated annual school tax |
|---|---|---|---|---|---|---|
| Modest single-family | $200,000 | $140,000 | $25,000 | $115,000 | 25 | $2,875 |
| Mid-range single-family | $325,000 | $260,000 | $30,000 | $230,000 | 25 | $5,750 |
| Higher-end property | $475,000 | $350,000 | $30,000 | $320,000 | 30 | $9,600 |
What to notice:
- A property listed at $200,000 can show a much lower assessed value if the county has not reassessed recently. That gap is normal.
- School taxes are calculated on the assessed value after any homestead exclusion, not on the sale price.
- If no homestead applies, the school tax is calculated on the full assessed value.
Action steps for sellers in Harrison City
- Pull your current assessed value and confirm whether your homestead status is on file before listing.
- Set your list price using a current CMA and, if needed, a pre-listing appraisal to anchor market value.
- If your assessment looks off, start the informal review or appeal process early and gather comps, photos, and documentation.
- Share a realistic tax estimate with buyers using the assessed value, homestead status, and the latest school millage.
Action steps for buyers in Harrison City
- Get the property’s current assessed value and ask for the latest tax bill to see whether a homestead exclusion is already applied.
- Build a tax estimate with two scenarios: current assessed value and a future reassessment scenario if you expect changes ahead.
- If you will occupy the home as your primary residence, apply for the homestead exclusion after closing following county instructions.
- Keep an eye on annual millage updates from the school district and local municipalities.
Pro tips and caveats
- Millage rates and exclusion amounts change, often yearly. Confirm the latest numbers before finalizing a budget.
- The assessed value shown in county records is your starting point for today’s tax estimate. A pending reassessment can change outcomes.
- Improvements and permits may trigger assessment updates. If you remodel, keep documentation and watch for notices.

FAQs
What is the difference between assessed and market value for a Harrison City home?
- Market value is the likely sale price based on comps and buyer demand, while assessed value is set by the county for property taxes and may lag the market.
Does my sale price become the new assessed value in Westmoreland County?
- Not automatically. Sales feed the county’s mass appraisal data, but assessed values change through reassessments or administrative updates.
Will my taxes jump right after I buy if I paid more than the assessed value?
- Not necessarily. Your bill is based on the current assessed roll until the county updates it, though future reassessments can reflect higher neighborhood sales.
How does the Pennsylvania homestead exclusion lower my school taxes?
- If the home is your primary residence and you file, a set exclusion amount is subtracted from your assessed value for school tax calculations, lowering the school tax portion.
How do I estimate school taxes on a Harrison City property?
- Use the formula: (Assessed Value − Homestead Exclusion, if eligible) × School Millage. Remember that 1 mill equals $1 per $1,000 of assessed value.
Where can I find current millage rates and homestead details for Westmoreland County?
- Check the county’s official tax and assessment resources and your school district’s published millage schedules, which are updated annually.
