What this commute costs you

What this page does not cover
- One thing worth being clear about, because it catches people out. You are not charged by both places. Tredyffrin Township and Philadelphia 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 Tredyffrin Township and Philadelphia. This page is about the layer that does.
- Sixty thousand a year is a benchmark. It is not a guess at what people in Tredyffrin Township earn. No published wage figure exists for single municipalities. The rate is the durable part of this page. The dollars scale straight up and down with whatever you earn in Philadelphia.
- Two practical cautions. Postal addresses and taxing boundaries do not always agree. Your post may say Tredyffrin Township while your taxing municipality is a different one. Pennsylvania publishes an official lookup to settle it. The same caution applies at the Philadelphia end. Philadelphia is a special case too, with its own wage tax.
- Pennsylvania's local rule is a greater-of rule, not an additive one: the liability for a Tredyffrin Township resident working in Philadelphia 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 Tredyffrin Township–Philadelphia municipal boundary, which is precisely why they are excluded: isolating the layer that responds to the commute is the point of the comparison.
- The reference salary is a stated benchmark, not an estimate of Tredyffrin Township earnings, for which no municipal-level published source exists. The local earned income tax is proportional, so all dollar figures for the Philadelphia commute scale linearly with income and the rate comparison holds at every salary.
- Two caveats bear on accuracy. First, postal addresses and municipal taxing boundaries diverge frequently in Pennsylvania, so a Tredyffrin Township address should be confirmed against the DCED municipal lookup before relying on the Tredyffrin Township rate. Second, Philadelphia administers its wage tax outside this framework, with its own resident and non-resident rates and its own credit arrangements, so any pairing touching it should be checked against the city's own schedule.
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 Tredyffrin Township's about 0% and Philadelphia's about 3.43%, the larger governs — the two are never added together.
What does crossing this boundary actually cost me?
$2,058 a year more than if you worked where you live. It is not a commuting charge and it buys you nothing — it is what falls out of two jurisdictions both having a claim and only one of them yielding.
Which town's rate am I actually paying?
The one where you work. Philadelphia levies more than Tredyffrin Township does, so its rate is the one applied and the difference is distributed between them afterwards.
Is this a common enough commute to be worth modeling?
1,928 workers make it. The pairing comes from federal commuting data rather than from guesswork, and thin routes are excluded rather than estimated.
My own town charges no income tax — so why is any taken?
Living in an untaxed town is not the same as earning in one. Tredyffrin Township charges nothing; Philadelphia charges about 3.43% to anyone working within it.
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 0%) and the non-resident work rate (about 3.43%); 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.
What is the marginal local tax cost of this commute?
Marginal annual liability attributable to working outside the residence jurisdiction is $2,058 at the reference salary. This is a tax cost rather than a commuting expense and is not deductible as one. It scales with income and with the rate differential, not with distance traveled.
Which district's rate governs on this route?
The work district's non-resident rate exceeds the residence rate and therefore governs. Withholding occurs at that rate, and distribution between the two districts happens after collection without further employee liability.
What is the basis for including this route?
Route volume is 1,928 workers, sourced from Census LODES origin-destination data. Pairs below the publication threshold are excluded rather than imputed, so page existence reflects measured commuting volume.
How does a zero residence rate interact with a work-district levy?
A zero residence rate removes the residence claim but not the work-district claim. Philadelphia levies about 3.43% on non-resident earnings sourced within it, and with no residence tax there is no credit mechanism to offset it against.
