Pennsylvania is the strangest entry in this series, and the strangeness is worth stating up front: for many Pennsylvanians, the income tax case for Florida is the weakest in the country — and the estate case is one of the strongest.
The income side first. Pennsylvania’s flat 3.07% is the lowest top rate of any state with an income tax this blog has covered. And for retirees it gets better: Pennsylvania exempts essentially all retirement income — Social Security, pensions, 401(k) and IRA distributions for those of retirement age — from tax entirely. A retired Pennsylvania couple living on $300,000 of pension and IRA income may owe Pennsylvania nothing. Moving to Florida saves them no income tax at all.
And yet the corridor from Philadelphia and Pittsburgh to the Gulf coast is one of the busiest in the migration. The reasons are on the death side of the ledger, in a city wage tax that working Philadelphians know intimately, and — for the high earners and business sellers — in the way a flat 3.07% still bites a nine-figure year. The Pennsylvania move requires knowing which Pennsylvanian you are. Here is the full map.
The Inheritance Tax: Dollar One, Every Estate
Most states that tax at death levy an estate tax with a large exemption — Illinois exempts $4 million, Minnesota $3 million. Pennsylvania does something different and, for ordinary families, harsher: an inheritance tax with effectively no exemption, levied on what each beneficiary receives, at rates set by relationship:
- 0% to a surviving spouse (and to charity);
- 4.5% to children, grandchildren, and other lineal descendants;
- 12% to siblings;
- 15% to everyone else — nieces, nephews, friends, partners not married.
Read the middle line again. There is no $14 million federal-style exemption, no $4 million Illinois-style floor. A Pennsylvania parent leaving a $2 million estate to two children generates a $90,000 Pennsylvania inheritance tax bill — on an estate that would owe zero in forty other states. Leave it to a sibling and the bill is $240,000. The tax applies to estates that will never see a federal estate tax return, which is precisely why it touches far more families than the millionaire-bracket dramas elsewhere in this series.
Florida domicile removes the inheritance tax from everything except Pennsylvania-situs real property. Florida has no estate tax, no inheritance tax, and a constitutional bar on creating one. For the retiree whose income Pennsylvania already declines to tax, this is usually the entire financial case for the move — and at 4.5% of everything passing to the kids, it is routinely a six-figure case. The wrinkle to plan around: the Bucks County house or the Poconos place stays within Pennsylvania’s reach as long as you own it directly at death, the same situs logic as Minnesota’s, with the same entity-planning conversation to have before the move.
What the Income Tax Case Looks Like (When There Is One)
For working and selling Pennsylvanians, the income picture sharpens quickly.
Philadelphia. The city’s wage tax on residents runs near 3.75% — on top of the state’s 3.07%. A Philadelphia executive’s true rate approaches 6.9%, which is no longer a rounding error: on $1 million of compensation, the combined annual claim approaches $69,000. Pittsburgh and many municipalities levy smaller local earned-income taxes, typically around 1%. If your Pennsylvania address is in a taxing city, compute your real combined rate before deciding the income case is weak.
The liquidity event. Flat and low is still flat: a founder recognizing a $30 million gain as a Pennsylvania resident owes roughly $920,000 to Harrisburg — plus the city’s cut if Philadelphia can claim them. The move-first sequencing logic applies in full: residency at recognition decides whose gain it is, the move has to be genuine and early, and the post-sale audit should be assumed.
The working wealthy. Between state and city taxes on large W-2 and pass-through income, high-earning Pennsylvanians save real money in Florida — just less of it than their neighbors from New York or New Jersey, which is why the estate side usually leads the analysis here rather than trailing it.
Pennsylvania’s Residency Rules: Standard Machinery, Fully Armed
Pennsylvania’s reputation as a low-drama tax state sometimes gets read as “Pennsylvania won’t chase you.” The machinery says otherwise.
Pennsylvania taxes you as a resident if you are domiciled there — the usual center-of-life test, persisting until you genuinely establish domicile elsewhere — or if you are a statutory resident: a permanent abode in Pennsylvania plus more than 183 days of presence in the year. That is the same trap this blog has documented in every state that runs one, and it means the Pennsylvanian who “moves” to Florida while keeping the Main Line house and the majority of the calendar has moved nothing.
The practical defense is the one that never changes: a genuine relocation of life’s center, the Florida checklist executed completely — declaration of domicile, license, voter registration, homestead — and a day count won with margin on both boards: Florida above 183, Pennsylvania comfortably below it, documented day by day. One Pennsylvania-specific note: the inheritance tax gives the Commonwealth a reason to examine domicile after death that income-tax states lack. Your residency file can be audited posthumously, with your executor defending it; the contemporaneous record you keep now is, quite literally, part of your estate plan.
The Practical Timeline
The Pennsylvania sequence follows the standard playbook with the estate-driven additions:
Before the move year: if a sale or large recognition event is coming, complete the genuine move at least a full tax year first. If the move is estate-driven, involve the estate attorney now — beneficiary designations, the treatment of retained Pennsylvania real estate, and the will’s situs language should all change with the domicile.
The move itself: the full Florida checklist, plus the Pennsylvania-side cleanup — close out local earned-income tax registrations, surrender the Pennsylvania license, and address the retained real estate’s titling.
The first full year: win the count — 200+ documented Florida days, Pennsylvania well under 183 — and live the holidays, the doctors, and the patterns from Florida. Both spouses, aligned; a split household undermines the inheritance-tax planning as thoroughly as the income side.
The part-year return: file PA-40 as part-year, with a residency-end date the evidence supports.
A Note on Consulting a Tax Professional
The Pennsylvania move is two plans wearing one coat: an income-tax relocation (standard) and an inheritance-tax restructuring (not standard). The second one reaches into your will, your beneficiary designations, your real-estate titling, and your family’s expectations, and it outlives you. A Pennsylvania-experienced estate attorney working alongside your CPA is not optional here — it is most of the project.
Where Southbound Fits
Whichever Pennsylvanian you are — the Philadelphia earner, the selling founder, the retiree moving for the 4.5% — the position rests on the same foundation: where you actually were, day by day, provable on demand. The income audit asks it of you; the inheritance-tax examination may one day ask it of your executor.
Southbound is an iOS app that builds that record passively. iOS’s significant-location-change system — not battery-draining GPS — logs each day as a Florida or non-Florida day automatically, with location evidence behind every entry. The Departure Budget keeps the both-boards arithmetic visible as one number all year, and the whole record lives in your own iCloud account — Southbound runs no servers and never sees your location history — exporting to CSV whenever your accountant, your attorney, or your estate needs it.
Southbound is on the App Store, free during the early-adopter launch period. For a move whose audit might happen decades from now, the contemporaneous record is the one thing that can’t be created later.
