If you’ve opened your mail lately in Lancaster County, you’ve probably seen a number that made your jaw drop. For many homeowners—especially here in Columbia Borough—property assessments jumped dramatically. But before panic sets in, it’s important to understand what those numbers actually mean, and what they don’t.
The Big Picture: What Just Happened?
Lancaster County is in the middle of a countywide property reassessment for tax year 2027, with notices mailed around June 15, 2026.
This is the first reassessment since 2018, and it’s meant to update property values to reflect today’s real estate market.
Over the past several years, housing prices have increased significantly—so now the county is catching up its official records to that reality.
In simple terms:
Your new assessment is the county’s estimate of what your home would sell for today.
Why Columbia Borough Got Hit So Hard
Here’s the part that has a lot of Columbia residents talking:
- The average assessment increase countywide is about 90%
- But Columbia Borough saw the largest jump—around 140.74%
That means a home previously assessed at $150,000 could now be valued around $360,000 on paper.
Why such a big jump here?
Columbia has historically had lower assessed values compared to actual market prices. Over the last decade, the borough has seen:
- Increased demand for affordable housing
- Renovation and revitalization
- Market prices rising faster than assessments
This reassessment is essentially closing that gap all at once.
The Most Important Truth: This Is NOT a Tax Increase (By Itself)
This is where most people get confused.
A higher assessment does NOT automatically mean your taxes will double.
Here’s why:
Pennsylvania Law Requires “Revenue Neutrality”
After a reassessment:
- Taxing bodies (county, borough, school district) must lower their tax rates (millage)
- They cannot collect more total tax revenue just because values went up
So yes—your home value may have doubled on paper, but the tax rate will drop to compensate.
So… Will Your Taxes Go Up?
The honest answer:
It depends on how your property compares to everyone else’s.
Property taxes are based on a simple formula:
Assessed Value × Tax Rate (Millage) = Your Tax Bill
The key is this:
You’re not taxed based on your value alone—you’re taxed based on your value relative to everyone else in the county.
What this means for Columbia residents
Because Columbia saw larger increases than most other areas, there’s a strong possibility that:
- Some homeowners will see tax increases
- Others may see little change or even decreases
This happens because:
- If your property value rose more than average, your share of the tax burden goes up
- If it rose less than average, your share goes down
Breaking Down Your Current Tax Structure
In Columbia Borough (based on recent rates):
- County tax: ~2.9 mills
- Borough tax: ~10 mills
- School tax (Columbia Borough School District): ~25.66 mills
Total: roughly 38.5 mills before reassessment adjustments
Important: These numbers will change for 2027 and cannot be used to estimate your new bill yet.
What You Should Do Right Now
1. Look at Your New Value Realistically
Ask yourself:
Could I actually sell my house for this amount today?
If yes, your assessment may be accurate.
2. Consider an Appeal (If Needed)
You have about 40 days from your notice date to appeal.
Appeals are based on market value accuracy, not whether your taxes feel too high.
3. Don’t Panic Over Headlines
You’ll see phrases like:
- “Values doubled”
- “Biggest increase in the county”
Those are true—but incomplete.
The tax system adjusts after reassessment.
The real impact depends on the new millage rates set in 2027.
What This Really Means for Columbia’s Future
While stressful, this reassessment also signals something important:
Property values in Columbia have significantly improved
The borough is becoming more attractive to buyers
Long-term investment in the area is increasing
That’s good for:
- Local businesses
- Property owners building equity
- Community revitalization
But it also creates real concerns:
- Affordability for longtime residents
- Pressure on fixed-income homeowners
- Risk of displacement if taxes rise unevenly
The Bottom Line
For Columbia Borough residents, the 2026 reassessment means:
- Your property value likely jumped significantly on paper
- Your tax rate will drop, but not evenly for everyone
- Your final tax bill depends on how your increase compares to others
- Some people will pay more—but others won’t
Final Thought
This isn’t just a tax story—it’s a market reality check.
Columbia isn’t the same town it was in 2018. The reassessment simply put numbers to what’s already been happening: growth, change, and rising value.
The real question now is how that growth gets managed—so it benefits the whole community, not just the balance sheets.
