Crossing the state line from Pennsylvania into Delaware is one of the most popular moves in our entire region.
And it's easy to see why. For buyers near the border — think Kennett Square, West Chester, or the greater Philadelphia suburbs — Delaware offers lower housing costs, famously low property taxes, no sales tax, and easy access to the very same Brandywine Valley they already love.
But here's the part most people get wrong: Delaware isn't automatically cheaper on every tax. The real picture is more nuanced — and understanding it before you move can save you real money.
Here's what Pennsylvania buyers need to know before making the move to Delaware.
🗺️ Why PA Buyers Move to Delaware
Every year, thousands of Pennsylvanians make the move south of the line — and the reasons are compelling:
✔️ Lower overall housing costs than many PA suburbs
✔️ Property taxes among the lowest in the entire country
✔️ No state sales tax on anything, ever
✔️ No estate or inheritance tax
✔️ Easy access to the Delaware beaches for weekends or retirement
For border-town buyers especially, you can often keep your same doctors, shopping, and Brandywine Valley lifestyle — just with a different tax address.
💰 The Tax Truth: PA vs. Delaware
Let's clear up the biggest misconception right away.
Income tax: Pennsylvania has a flat 3.07% income tax. Delaware's is graduated and tops out at 6.6% on income over $60,000 — which means most working households actually pay more income tax in Delaware than in PA.
So how does Delaware still come out ahead for so many buyers? Two big reasons:
✔️ No sales tax. Pennsylvania charges 6% (and 8% in Philadelphia). Delaware charges nothing — saving a typical household well over $2,000 a year on everyday purchases, cars, and big-ticket items.
✔️ Ultra-low property taxes. Delaware's effective property tax rate sits around 0.55% — among the lowest in the U.S. Many Pennsylvania districts run significantly higher.
Add in no estate or inheritance tax (Pennsylvania has an inheritance tax), and for most homeowners and moderate-to-high spenders, Delaware's total tax burden comes out lower — despite the higher income tax rate.
The key word is most. Your personal result depends on your income and how much you spend, so it's worth running your own numbers.
🧓 What About Retirees?
Here's where it gets interesting — because Pennsylvania is genuinely retiree-friendly, too.
Pennsylvania fully exempts retirement income: pensions, 401(k) and IRA distributions, and Social Security are all tax-free for PA retirees.
Delaware is also friendly, but slightly less so on income: it fully excludes Social Security and offers a pension exclusion of up to $12,500 for residents 60 and older.
However, Delaware counters with powerful perks retirees love:
✔️ No sales tax and very low property taxes
✔️ No estate or inheritance tax
✔️ A Senior School Property Tax Credit for qualifying residents 65+
For many retiring homeowners, Delaware's lower everyday costs offset the modest income-tax difference — especially if the beaches are calling.
🚗 Practical Steps: Making the Move Official
Once you've decided, Delaware makes new residents official fairly quickly. Plan to handle a few things soon after moving (generally within about 60 days):
✔️ Get a Delaware driver's license
✔️ Title and register your vehicles — Delaware charges a 4.25% document fee instead of sales tax on vehicles, typically lower than neighboring states
✔️ Complete any required vehicle inspection
✔️ Update your voter registration and address
Establishing Delaware residency also matters for tax purposes, so keep good records of your move date.
🏠 The Home-Buying Differences
The buying process itself has a few Delaware-specific wrinkles worth planning for:
✔️ Transfer tax. Delaware's realty transfer tax is higher than Pennsylvania's — generally around 4% of the purchase price, often split between buyer and seller, with relief available for qualified first-time buyers. Budget for this one-time closing cost.
✔️ The recent reassessment. New Castle County recently completed its first property reassessment in decades, so always confirm the current assessed value and actual tax bill for any specific home rather than relying on old estimates.
✔️ Wilmington's local tax. If you'll live and work within the City of Wilmington, note that the city levies its own local wage tax.
✔️ Remote workers, take note. Where your income is taxed can get complicated if you cross state lines for work — especially with remote arrangements. If that's your situation, talk to a CPA before you move.
📍 Where PA Movers Are Landing
Most Pennsylvania buyers moving into Delaware focus on New Castle County, which sits right against the PA line. Popular landing spots include:
✔️ Hockessin & Greenville — upscale, wooded, and just minutes from the PA border, with top schools
✔️ Newark — a lively college town with great value and strong amenities
✔️ Middletown — fast-growing, with new construction and top-ranked Appoquinimink schools
✔️ Pike Creek, Bear & Glasgow — suburban value with easy access to everything
✔️ Wilmington — riverfront revitalization and city convenience
And for those thinking about a weekend place or retirement, the Delaware beaches around Lewes and Rehoboth remain perennial favorites.
🔑 Tips for a Smooth PA-to-Delaware Move
A little planning goes a long way. Keep these in mind:
Run Your Own Numbers
Compare your income and spending in both states — the "cheaper" option depends on your specific situation.
Verify Taxes and Schools by Address
Confirm the actual property tax bill and school assignment for any home before you commit.
Budget for the Transfer Tax
Plan for Delaware's one-time transfer tax, and ask whether you qualify for first-time buyer relief.
Work With an Agent Licensed in Both States
Cross-border moves have real nuances — an agent who knows both PA and Delaware is invaluable.
Consult a CPA for Complex Situations
Especially for retirees, remote workers, and higher earners, professional tax advice pays for itself.
Final Thoughts
Moving from Pennsylvania to Delaware can be a genuinely smart financial and lifestyle decision — but only when you understand the full picture.
Yes, Delaware's income tax is higher than Pennsylvania's. But no sales tax, ultra-low property taxes, no estate or inheritance tax, and lower housing costs often add up to a real win — especially for homeowners.
The best move is an informed one: run your numbers, verify the details, and lean on local expertise.
If a move across the line is on your mind, the smartest first step is a conversation with someone who knows both sides of the border — and can help you find the right home in the right community. 🏡
