What this commute costs you
no extra local taxPhiladelphia already charges its residents more than Swarthmore Borough 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 Swarthmore Borough costs you nothing extra. Philadelphia charges residents about 3.74%, at least as much as Swarthmore Borough 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.
- Not many people do this journey. Swarthmore Borough is 65 of 69 destinations for Philadelphia residents, with roughly 556 making the trip. Same rule, fewer people.
- For the Philadelphia to Swarthmore Borough commute the residence governs. Philadelphia's resident rate of about 3.74% equals or exceeds Swarthmore Borough'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.
- Swarthmore Borough ranks 65 of 69 destinations for Philadelphia, carrying 556 workers. Flows in the lower band still reflect real employment links, but the aggregate fiscal consequence of the rate outcome here is correspondingly limited.

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 Swarthmore Borough 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.
- This covers the local tax only. Whatever Philadelphia or Swarthmore Borough takes sits on top of state tax, federal tax and Social Security. Those three do not care where you live or work.
- 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 Swarthmore Borough 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 Swarthmore Borough.
- Pennsylvania's local rule is a greater-of rule, not an additive one: the liability for a Philadelphia resident working in Swarthmore Borough 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.
- Only the local earned income tax component is modeled for the Philadelphia to Swarthmore Borough commute. State and federal liabilities are constant across Pennsylvania municipalities and are excluded so the municipal differential is visible rather than buried inside a larger total.
- 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 Swarthmore Borough 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 Swarthmore Borough 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 Swarthmore Borough's about 0%, 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?
The one where you live. Philadelphia levies at least as much as Swarthmore Borough, so its rate applies and the crossing costs you nothing extra.
Is this commute common enough for the numbers to mean anything?
556 workers make this journey — enough to be published, but not a major corridor. The tax rules do not depend on how many people travel a route, so the figures hold regardless; the count only tells you how typical this pairing is.
The town I work in charges nothing — does that help me?
It does not save you. Swarthmore Borough takes nothing, but Philadelphia taxes you as a resident at about 3.74% regardless of where the job sits.
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 0%); 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 556 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.
What is the effect of a zero work-district rate?
A zero work-district rate eliminates the source-based claim but leaves residence-based liability intact at about 3.74%. Residence liability is unaffected by where earnings are sourced.
