You live in Pennsylvania.
Your sister lives in New Jersey.
You each have a house, retirement accounts, investments and a reasonably successful financial life.
You each leave $2 million to your children.
You die.
She dies.
Same amount of money. Same type of beneficiaries. Houses separated by perhaps 30 miles.
Surely the tax result is basically the same.
Not necessarily.
Welcome back to Death Has a ZIP Code, our slightly morbid tour through one of estate planning’s most overlooked realities:
Where you live—and sometimes where your property is located—can affect what your family receives when you die.
And nowhere is this more interesting for people in our area than the Pennsylvania-New Jersey border.
Thousands of people cross between the two states every day without giving it a second thought.
You can live in Pennsylvania, work in New Jersey, own a Shore house in New Jersey, have children living in both states, and be at dinner in Philadelphia by 7:00.
But when you die?
Suddenly that invisible line in the middle of the Delaware River can become very important.
Let’s talk about why.
Pennsylvania Has a Tax Many People Don’t Know Exists
Ask the average Pennsylvania resident about estate taxes and you may hear:
“My estate isn’t big enough to worry about that.”
They may be thinking about the federal estate tax.
And for most people, they’re right.
In 2026, the federal estate-tax filing threshold is $15 million per individual. Most American families are nowhere near it.
But Pennsylvania has its own system.
And Pennsylvania doesn’t call it an estate tax.
It imposes an inheritance tax.
That distinction matters because you don’t need to be extraordinarily wealthy for Pennsylvania inheritance tax to become relevant.
You don’t need $15 million.
You don’t need $10 million.
You don’t even need $5 million.
A relatively ordinary Pennsylvania estate can potentially generate Pennsylvania inheritance tax.
Pennsylvania’s Question Isn’t Just “How Much?”
Pennsylvania asks another important question:
“Who gets the money?”
The tax rate depends significantly upon the relationship between the person who died and the beneficiary.
Under current Pennsylvania rules, the headline rates generally include:
0% for qualifying transfers to a surviving spouse;
4.5% for transfers to direct descendants and other lineal heirs;
12% for transfers to siblings; and
15% for transfers to many other beneficiaries.
That produces some fascinating—and occasionally painful—results.
Let’s meet our fictional Pennsylvania resident.
Meet Uncle Charlie
Uncle Charlie lives in Montgomery County.
Charlie never married and has no children.
He has done well.
His estate is worth $2 million.
Charlie has two people he loves dearly:
His brother, Sam.
And his niece, Emily.
Charlie decides to split his estate equally between them.
Simple.
Sam receives $1 million.
Emily receives $1 million.
But Pennsylvania does not necessarily view those two gifts the same way.
The transfer to Charlie’s brother may fall under the 12% sibling rate.
The transfer to his niece may generally fall under the 15% rate applicable to many other beneficiaries.
Charlie might think:
“They’re both my family.”
Pennsylvania’s tax code responds:
“Yes. But what kind?”
That is why beneficiary selection matters in Pennsylvania estate planning.
The family tree can effectively become part of the tax calculation.
Now Move Charlie Across the River
Let’s change one fact.
Charlie sells his Pennsylvania home and becomes genuinely domiciled in New Jersey.
Same $2 million.
Same brother.
Same niece.
Same will.
Same basic investments.
Does anything change?
Potentially, yes.
New Jersey also has an inheritance tax, but its system classifies beneficiaries differently.
And those classifications can create dramatically different results.
This is where the comparison gets interesting.
New Jersey Got Rid of Its Estate Tax
First, some history.
New Jersey once had an estate tax.
It doesn’t anymore.
For deaths occurring after January 1, 2018, New Jersey no longer imposes its former estate tax.
That sounds wonderfully simple.
New Jersey estate tax: gone.
But don’t celebrate quite yet.
New Jersey retained its inheritance tax.
So when someone tells you:
“New Jersey doesn’t have a death tax anymore,”
your response should be:
“Which death tax?”
Because New Jersey’s inheritance tax is alive and well.
New Jersey Has Classes—and You Want to Be in the Right One
New Jersey divides beneficiaries into different classes.
This isn’t first class, business class and economy.
Although, financially speaking, it can feel that way.
Certain close family members fall into Class A and are exempt from New Jersey inheritance tax.
This generally includes beneficiaries such as:
- spouses and civil-union partners;
- children and other lineal descendants;
- parents and grandparents; and
- certain other qualifying relationships.
So let’s imagine Mom dies as a New Jersey domiciliary and leaves $2 million to her daughter.
Subject to the applicable rules, that daughter can generally fall within an exempt Class A relationship.
Compare that with Pennsylvania.
A Pennsylvania parent’s transfer to a child is generally subject to a 4.5% inheritance-tax rate.
Now we have a real difference.
The $2 Million Example
Let’s keep this deliberately simple.
Pennsylvania Mom dies and leaves $2 million of property subject to Pennsylvania inheritance tax to her adult child.
At 4.5%, the tax would be approximately:
$90,000.
New Jersey Mom dies and leaves the same $2 million to her child.
If the child qualifies as an exempt Class A beneficiary, New Jersey inheritance tax on that transfer can be:
$0.
Same $2 million.
Same mother-child relationship.
Different state.
Potential difference:
$90,000.
Now you understand why we call this series:
Death Has a ZIP Code.
Of course, actual estates are more complicated. Deductions, jointly owned property, retirement accounts, real estate, beneficiary designations and other rules can affect the calculation.
But the example illustrates the fundamental point.
State law matters even when federal estate tax doesn’t.
So New Jersey Wins?
Not so fast.
If all you knew was the parent-to-child example, you might conclude:
“Great. Everybody move to New Jersey.”
That would be a very bad way to do estate planning.
Remember what we said earlier:
Inheritance taxes care about relationships.
Change the beneficiary and you can change the result.
New Jersey’s inheritance-tax system has different rules for beneficiaries outside its exempt Class A category.
That can include siblings and other beneficiaries.
So New Jersey may look extremely attractive in one family situation and considerably less attractive in another.
The question isn’t:
“Which state has lower inheritance taxes?”
The better question is:
“Which state’s rules are better for my assets and my beneficiaries?”
Your Child and Your Brother Are Not Tax Twins
This is one of the most useful lessons for clients.
Suppose you have a $3 million estate.
You have no spouse.
Your will says:
50% to your daughter.
50% to your brother.
From your perspective, you are leaving money to two close members of your family.
From the tax system’s perspective, those are two entirely different transfers.
The identity of the beneficiary can determine whether an inheritance is exempt, taxed at a particular rate, or subject to a different set of rules.
This means estate planning should never consist solely of asking:
“What am I worth?”
We also need to ask:
“Who is getting it?”
What About Unmarried Partners?
Here’s where inheritance taxes can become particularly surprising.
Imagine a couple who have lived together for 25 years.
They own a home.
They share expenses.
They travel together.
Everyone considers them a family.
But they never married.
One dies and leaves everything to the other.
From an emotional standpoint, the surviving partner may essentially be a spouse.
The tax code doesn’t necessarily care about the emotional standpoint.
Legal relationships matter.
Depending upon the state and exact circumstances, the tax treatment of an unmarried partner can be dramatically different from the treatment of a spouse.
That can turn what seemed like a perfectly reasonable estate plan into a significant tax event.
It is one reason unmarried couples should pay particularly close attention to estate planning.
“We’ve been together forever” is not a tax classification.
Your Will Doesn’t Control Everything Either
Here’s another common misconception.
“I put everything in my will.”
Wonderful.
Now let’s look at everything that may not pass under the will.
Your IRA may have a beneficiary.
Your 401(k) may have a beneficiary.
Your life insurance has a beneficiary.
Your jointly titled bank account may pass according to its ownership arrangement.
Your house may be jointly owned.
You might have payable-on-death or transfer-on-death accounts.
You may have a trust.
Estate planning is not just will planning.
And inheritance-tax planning isn’t either.
You have to understand how each asset passes, to whom it passes, and how that transfer is treated.
“Fine. I’ll Just Move to New Jersey Before I Die.”
I admire your enthusiasm.
But this is where our discussion gets more complicated.
Moving is not just a paperwork exercise.
If you want another state to become your legal domicile, the facts need to support that conclusion.
You generally can’t spend virtually your entire life in Pennsylvania, buy a small New Jersey property shortly before death, change one mailing address and announce:
“Surprise! I’m from Jersey now.”
Domicile generally concerns your true, fixed and permanent home.
The analysis can involve facts such as:
Where do you actually live?
Where are you registered to vote?
Where is your driver’s license?
Where are your vehicles registered?
Where do you receive mail?
Where do you spend your time?
Where are your doctors?
Where are your important personal belongings?
What addresses do you use on legal and financial documents?
Where does your spouse live?
Where are your strongest community connections?
What do your estate-planning documents say?
No single fact necessarily answers every domicile question.
The entire picture matters.
And Then There’s the House You Didn’t Sell
Let’s make it more interesting.
You genuinely move from Pennsylvania to New Jersey.
You establish New Jersey domicile.
But you keep a vacation home in Pennsylvania.
Can Pennsylvania simply be ignored because you no longer live there?
Not necessarily.
Real estate has a stubborn habit of remaining exactly where you left it.
A Pennsylvania house is still Pennsylvania real estate even if you are personally domiciled somewhere else.
That can create tax and probate issues requiring separate analysis.
This is an enormously important concept for retirees who own property in multiple states.
Changing your domicile does not teleport your assets across state lines.
What If You Move to Florida Instead?
Now our regional tax tour gets even more interesting.
Pennsylvania resident:
Inheritance tax.
New Jersey resident:
Inheritance tax, but important exemptions based upon beneficiary class.
Florida resident:
Florida does not currently impose a separate state estate tax or inheritance tax of the type we’re discussing.
Suddenly Florida starts looking pretty attractive.
And for a person with a substantial estate who was already considering relocating to Florida, the tax difference can be one legitimate factor in the decision.
But remember:
Taxes are one factor.
You should probably not leave your children, grandchildren, friends, doctors, favorite restaurants and entire social life just to save your heirs money someday unless the economics truly justify it.
The objective is to enjoy your life and have an intelligent estate plan.
Not to spend your retirement staring at a palm tree you hate while whispering:
“At least the inheritance tax is good.”
Sometimes You Don’t Need to Move at All
Before changing states, ask whether estate planning can improve the result.
Depending upon your assets, beneficiaries and objectives, potential strategies could involve:
- lifetime gifting;
- irrevocable trusts;
- charitable planning;
- life-insurance planning;
- business-succession planning;
- ownership restructuring;
- beneficiary-designation planning;
- planning for jointly owned assets;
- strategic use of exemptions;
- or other state-specific techniques.
Not every strategy eliminates inheritance tax.
Some transfers made shortly before death may also be subject to special rules.
And moving property into a trust does not automatically make taxes disappear.
But planning should occur before you decide that moving is your only option.
Pennsylvania’s Discount for Being Early
Pennsylvania also gives us another example of why administration matters after death.
Pennsylvania provides a discount when inheritance tax is paid within the applicable early-payment period.
That means even after someone dies, deadlines and administration can affect the final tax bill.
A good estate plan therefore isn’t only about drafting documents while you’re alive.
It is also about making things easier and more efficient for the people administering your estate after your death.
The executor who knows what needs to happen—and does it promptly—can be worth a lot more than people realize.
Federal Estate Tax Is Still Sitting in the Background
None of this eliminates federal law.
For 2026, the federal estate-tax filing threshold is $15 million per individual.
If your estate is large enough, you may need to think about federal estate tax regardless of whether you live in Pennsylvania, New Jersey or Florida.
At that level, the planning becomes more sophisticated.
Now we may be talking about:
Irrevocable trusts.
Lifetime gifting.
GRATs.
SLATs.
Dynasty trusts.
Life-insurance trusts.
Generation-skipping planning.
Charitable strategies.
Business valuation.
Liquidity planning.
And the strategic transfer of appreciating assets.
Changing domicile might save state taxes.
It does not make federal estate-tax law disappear.
The Bigger Lesson: Your Address Is Part of Your Estate Plan
Most people think estate planning means:
Will. Trust. Power of attorney. Done.
But a sophisticated estate plan considers much more.
It considers:
What do you own?
Where is it located?
How is it titled?
Who receives it?
What is that person’s relationship to you?
Where are you domiciled?
Where are your beneficiaries located?
What taxes apply?
What happens if you move?
And:
Does your current plan still make sense after the move?
That last question gets overlooked constantly.
A will or trust drafted when you lived in Pennsylvania shouldn’t simply be shoved into a drawer for 20 years after you relocate to another state.
Moving is an excellent time for an estate-plan review.
Pennsylvania vs. New Jersey: Who Wins?
Everyone wants a winner.
So here it is:
It depends.
I know.
Terribly unsatisfying.
But it’s the correct answer.
For a parent leaving substantial assets to children, New Jersey’s Class A exemption can make its inheritance-tax treatment look significantly more favorable than Pennsylvania’s 4.5% lineal-descendant rate.
Change the beneficiary to a sibling, niece, nephew, friend or unmarried partner and the comparison can change.
Own real estate on the other side of the border and the analysis changes again.
Have a federally taxable estate and we add another layer.
Have a family business?
Another layer.
Own highly appreciated assets?
Now capital-gains basis planning enters the conversation too.
Estate planning is a giant game of:
“Yes, but what if…?”
And that’s precisely why personalized planning matters.
Death Has a ZIP Code—but Life Comes First
Here’s the part tax lawyers sometimes forget.
The best place to die is probably the place where you enjoyed living.
If your children and grandchildren are in Pennsylvania, you love your community, your friends are nearby and you can’t imagine living anywhere else, a 4.5% inheritance tax on a child’s inheritance probably shouldn’t automatically chase you across a state line.
But you should know about it.
And you should plan for it.
On the other hand, if you are already deciding whether to retire in Pennsylvania, New Jersey or Florida, taxes can absolutely belong on the spreadsheet.
For a sufficiently large estate, the difference may be tens of thousands, hundreds of thousands or potentially much more.
That’s real money.
Money that could go to your children.
Your grandchildren.
Your favorite charity.
Or wherever else you choose.
The Most Expensive Estate-Planning Mistake May Be Doing Nothing
The people who tend to have the most options are the people who plan while they are healthy.
Before the move.
Before selling the business.
Before making enormous gifts.
Before changing ownership.
Before dementia or incapacity becomes an issue.
And, ideally, long before anyone is sitting at a hospital bedside trying to figure out which state gets to call someone a resident.
You spent decades building your wealth.
A few hours spent understanding how Pennsylvania, New Jersey and federal law interact can be an excellent investment.
Because the goal isn’t to “beat” the tax system.
The goal is much simpler:
Understand the rules before the rules decide what happens to your money.
And remember:
Death has a ZIP code.
Make sure your estate plan knows yours.
