A move across a state line changes which state taxes your retirement income, but not in the way most people assume. Under federal law, the state you leave generally cannot tax your pension or retirement plan distributions once you are no longer a resident there.1 What follows you is not the old state's claim on your retirement income, it is the question of whether you genuinely changed domicile, which turns on facts rather than on a mailing address.
The most useful fact in this whole subject is a federal one, and it is not widely known.
Federal law prohibits a state from imposing income tax on the retirement income of someone who is not a resident of that state.1 The protection covers pensions and distributions from qualified retirement plans, and it means the state where you earned a pension cannot follow you after you leave. A career worked entirely in one state does not create a permanent claim on the income that career produced.
What that rule does not do is settle whether you actually left. That is the whole contest, and it is decided on domicile rather than on paperwork.
Domicile is the place you intend as your permanent home, and a state determines it by looking at behaviour rather than at declarations. New Jersey treats someone as a resident taxpayer if they are domiciled in the state, and separately if they maintain a permanent home there and spend more than a specified part of the year in the state.2
In practice the factors examined are mundane and cumulative. Where the home you treat as primary is. Where you spend your days, counted. Where you are registered to vote and licensed to drive. Where your vehicles are registered, where your doctors are, where your professional advisers are, where your immediate family lives, and where the things you would not leave behind are kept.
No single item decides it. A beach house in Delaware and a mail forwarding address do not establish domicile while the rest of the pattern stays in New Jersey. Conversely, someone who genuinely relocates and keeps a small property here has a defensible position.
This is not tax or legal advice. Residency determinations are fact-specific, the rules differ in every state, and a part-year move raises filing questions this article does not address. Work through any planned move with your CPA before the year in which it happens. Maisch Financial Group does not prepare tax returns.
If you leave and establish domicile elsewhere, New Jersey generally stops taxing the retirement income covered by the federal rule above. What it does not stop taxing is income sourced to New Jersey, which most commonly means rental income from property you keep here.
Selling the house introduces its own step. New Jersey requires a non-resident seller of real property to make an estimated payment at closing, which is a prepayment against the tax eventually calculated rather than an extra tax.3 It surprises people at the settlement table and is reconciled when the return is filed.
The timing of the move within the calendar year also matters, because a part-year resident files differently from a full-year one, and a large one-time event such as a conversion or a property sale lands in whichever state's year it falls into.
People move here too, often to be near adult children, and the picture is more favourable than the state's general reputation suggests.
New Jersey does not tax Social Security benefits.2 It also provides a pension and retirement income exclusion for qualifying residents at or above a specified age, subject to a total income limit that operates as a threshold rather than a taper.2 That mechanic is the one worth planning around and it is covered in How New Jersey Taxes Retirement Income.
Property tax is the offsetting consideration, and it varies widely between municipalities within the same county. A household comparing towns is comparing tax bills as much as houses.
For South Jersey households the nearest alternative is across the river, and the comparison comes up constantly.
Pennsylvania does not tax distributions from eligible retirement plans for residents who have reached retirement age as the state defines it, and it does not tax Social Security.4 On retirement income alone that is a meaningful difference from New Jersey, where pension and IRA income is taxable above the exclusion limit.
It is also only one line of the comparison. Property taxes, local earned income taxes, inheritance tax treatment, and the cost of actually moving all belong in the same calculation, as does the fact that New Jersey and Pennsylvania have a longstanding reciprocal agreement covering wage income rather than retirement income.4 Treating a single favourable rule as the whole answer is how people move for a tax saving and find it offset elsewhere.
A change of domicile reaches further than the income tax return, and this is the part most often missed.
New Jersey repealed its estate tax for deaths on or after January 1, 2018, but retains an inheritance tax that depends on the relationship between the deceased and the beneficiary.5 Other states make different choices, and some impose an estate tax at thresholds well below the federal one.
Beyond tax, the documents themselves are state-specific. A will, a power of attorney, and a health care directive drafted under one state's law may not operate the way you expect under another's, and the people you named may now be inconveniently distant. A move is a reason to have the documents reviewed by an attorney licensed in the new state, which is covered in Legacy Planning vs Writing a Will.
Cherry Hill is one of South Jersey's largest and best-known townships and a center of shopping, dining, and professional life, and we work with its professionals and retirees on every part of the retirement picture. The move question is unusually live there, because the Pennsylvania line is minutes away and a good number of the households we meet have family on both sides of the river. Anyone searching for a financial advisor in NJ on this question is usually weighing one favourable tax rule against a property tax bill, a care network, and a set of estate documents, which is exactly why it is not a tax question on its own. Our tax planning, retirement income planning, investment management, estate and legacy planning, and health care and Medicare planning are delivered as one engagement, so a relocation gets weighed against all of them at once rather than one at a time. Cherry Hill is a short drive from our Mount Laurel office, and we also meet by phone or video. The communities we serve are listed on our cities served page.
Generally no. Federal law prohibits a state from taxing the retirement income of someone who is not a resident of that state, and the protection covers pensions and distributions from qualified retirement plans. The state where you earned a pension cannot follow you after you genuinely leave. What New Jersey can still tax is income sourced to the state, most commonly rent from property you keep here.
Domicile, which is the place you intend as your permanent home, judged on behaviour rather than declarations. New Jersey also treats someone as a resident if they keep a permanent home in the state and spend more than a specified part of the year there. The factors examined are cumulative: where you actually spend your days, where you vote and are licensed, where your vehicles, doctors, advisers, and family are. A mailing address alone does not establish it.
On retirement income alone Pennsylvania is more favourable, because it does not tax distributions from eligible retirement plans for residents who have reached retirement age as the state defines it, and does not tax Social Security. That is one line of the comparison. Property taxes, local earned income taxes, inheritance tax treatment, and moving costs belong in the same calculation, and a single favourable rule is frequently offset elsewhere.
Not for deaths on or after January 1, 2018, when the estate tax was repealed. New Jersey does retain an inheritance tax, which depends on the relationship between the deceased and the beneficiary rather than on the size of the estate alone. Other states make different choices, and some impose an estate tax at thresholds well below the federal one, which is why a move is a reason to review the estate plan.
They should be reviewed by an attorney licensed in the new state. Wills, powers of attorney, and health care directives are drafted under a particular state's law and may not operate as expected elsewhere. The practical issue is often simpler than the legal one: the people named as agents or executors may now be a long way away, which matters most in exactly the circumstances the documents exist for.

Thresholds, exclusion limits, rates, and eligibility ages under these authorities are set by statute and are adjusted from time to time. This article describes how the rules operate rather than quoting current figures. Confirm the amounts that apply to you directly with the authority cited or with your tax professional.
