What this commute costs you
no extra local taxPhiladelphia already charges its residents more than Lower Gwynedd Township charges commuters, so the home rate governs and the job adds nothing at all. You pay the solid bar only — Pennsylvania charges the higher of the two rates, never their sum. Local earned income tax only; state, federal and payroll tax apply on top.
What this commute actually costs
- Good news for this commute. Working in Lower Gwynedd Township costs you nothing extra. Philadelphia charges residents about 3.74%, at least as much as Lower Gwynedd Township asks of people who work there but live elsewhere. The higher rate wins, so your home rate is simply the rate. That is $2,244 a year, wherever you work.
- A quiet route out of Philadelphia. About 624 people commute to Lower Gwynedd Township, placing it 54 of 69 tracked destinations. The arithmetic above holds regardless of how many travel it.
- For the Philadelphia to Lower Gwynedd Township commute the residence governs. Philadelphia's resident rate of about 3.74% equals or exceeds Lower Gwynedd Township's non-resident rate, so Pennsylvania's greater-of test resolves to the resident rate and the effective burden is about 3.74%, or $2,244 at the reference salary. The workplace adds nothing; the entire amount is remitted to the residence. This is the majority outcome and the one most commuters need confirmed.
- With 624 workers, this is a lower-volume link, 54 of 69 destinations recorded for Philadelphia. Volume does not affect the rate determination; it affects only how many people the determination reaches.

What this page does not cover
- One thing worth being clear about, because it catches people out. You are not charged by both places. Philadelphia and Lower Gwynedd Township do not add their rates together. Pennsylvania picks the higher of the two, and that is what you pay. Adding them would roughly double the bill.
- Everything here is the local earned income tax and nothing else. State income tax applies on top, as do federal tax and Social Security. None of those change when you cross a municipal line between Philadelphia and Lower Gwynedd Township. This page is about the layer that does.
- The dollar figures use a flat reference salary of sixty thousand a year. That is a benchmark, not an average for Philadelphia. No wage data exists for single municipalities, and inventing one would be worse. Scale the numbers to your own pay. The rate for the Lower Gwynedd Township commute is what matters, and it does not change with income.
- Check two things. A Philadelphia postal address may not match your taxing municipality. That catches out plenty of people near a boundary, and the state has an official lookup for it. Philadelphia is the other one to watch. It runs its wage tax separately, outside the pattern used for Lower Gwynedd Township.
- Pennsylvania's local rule is a greater-of rule, not an additive one: the liability for a Philadelphia resident working in Lower Gwynedd Township is the higher of the two applicable rates, not their sum. The distinction is worth stating plainly because the additive reading is intuitive and would overstate the charge by roughly a factor of two. What is divided between the municipalities is the remittance, not the worker's liability.
- Figures cover the local earned income tax exclusively. Pennsylvania's flat state income tax, federal income tax and FICA apply in addition and are invariant to the Philadelphia–Lower Gwynedd Township municipal boundary, which is precisely why they are excluded: isolating the layer that responds to the commute is the point of the comparison.
- Dollar amounts are computed against a stated reference salary rather than a municipal wage average, which does not exist for Pennsylvania municipalities in any published source. Because the local tax is flat, the rate is invariant to income and the figures scale linearly — the Philadelphia to Lower Gwynedd Township differential doubles at twice the salary and halves at half of it.
- Verify two things before relying on these figures. Municipal taxing boundaries do not track postal geography, so the applicable jurisdiction for a Philadelphia address should be confirmed through the state's official lookup. Separately, Philadelphia's wage tax operates outside this framework and is not governed by the greater-of rule applied here, which affects any pairing involving the city rather than Lower Gwynedd Township generally.
Questions people ask
Do I pay local tax twice — once where I work and once where I live?
Only once, at the higher rate. Between Philadelphia's about 3.74% and Lower Gwynedd Township's about 1%, the larger governs — the two are never added together.
Does working in a different town cost me anything?
On this route, nothing. You owe exactly what you would have owed working at home — the boundary is real on a map and invisible on your pay stub, which is not true of every pair of towns here.
Which town's rate am I actually paying?
Philadelphia sets it. Your residence rate is the larger, so it governs regardless of where the job is.
Is this commute common enough for the numbers to mean anything?
624 people travel it. Volume decides whether a route gets published at all, never what the tax on it is.
How does Pennsylvania's local earned income tax law allocate liability between two districts?
Pennsylvania's local earned income tax law assigns the higher of the residence rate (about 3.74%) and the non-resident work rate (about 1%); liabilities are never summed. The employer withholds at the governing rate and remits through the work district's collector, which then distributes to the residence district.
Why is the marginal cost of this crossing zero?
Marginal liability from working outside the residence jurisdiction is zero on this route. The crossing alters the distribution of revenue between jurisdictions but not the employee's total. ⚠️ This is route-specific and does not generalise to other pairs in the same dataset.
Which district's rate governs on this route?
The residence rate equals or exceeds the work district's non-resident rate and therefore governs. Working outside the residence district does not increase employee liability on this route; it affects only inter-district distribution.
What is the measurement basis for a route of this size?
Route volume is 624 workers per Census LODES, above the publication floor but below the dataset's upper quartile. Liability is determined by jurisdictional rates and residence rules alone; commuter volume has no bearing on it and is reported only as context.
