What this commute costs you
no extra local taxPhiladelphia already charges its residents more than Tredyffrin 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 Tredyffrin Township costs you nothing extra. Philadelphia charges residents about 3.74%, at least as much as Tredyffrin 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.
- This is the dearest way into Tredyffrin Township. Out of 8 routes tracked here, Philadelphia has the highest local rate. Same office, same salary, and you pay more local tax than colleagues who travel in from anywhere else on this list.
- Around 4,512 people make this trip from Philadelphia into Tredyffrin Township for work. It is a well-worn route. That is part of why the tax treatment is worth setting out.
- For the Philadelphia to Tredyffrin Township commute the residence governs. Philadelphia's resident rate of about 3.74% equals or exceeds Tredyffrin 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.
- Of 8 routes into Tredyffrin Township in this dataset, Philadelphia produces the highest effective rate. Because the local tax attaches to residence and workplace rather than to the employer, colleagues at one workplace routinely carry materially different local burdens, and this residence is at the top of that range.

What this page does not cover
- To be explicit, since the arrangement invites confusion. The rates for Philadelphia and Tredyffrin Township are not stacked. Pennsylvania takes the larger one. What is collected then gets divided between the two municipalities. That division does not change what comes out of your pay.
- Only one tax is on this page. It is the local earned income tax that Philadelphia and Tredyffrin Township levy. State tax, federal tax and Social Security all still apply. All three are the same wherever in Pennsylvania you work.
- Sixty thousand a year is a benchmark. It is not a guess at what people in Philadelphia 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 Tredyffrin Township.
- A postal address in Philadelphia does not prove which municipality taxes you. Boundaries and postcodes disagree often enough here that the state publishes a lookup. Philadelphia is a special case too. Its wage tax sits outside the rules that govern Tredyffrin Township.
- The two rates applicable to a Philadelphia–Tredyffrin Township commute are alternatives, not addends. The statute fixes the employee's liability at the greater of them and then apportions the proceeds, with the residence receiving up to its own rate and the excess passing to the work location. The apportionment is fiscally significant to the municipalities and immaterial to the worker.
- The scope here is the municipal earned income tax alone. State, federal and payroll taxes are unaffected by the choice between Philadelphia and Tredyffrin Township and are therefore outside the model. A total tax position requires adding them; a comparison of the two locations does not.
- The reference salary is a stated benchmark, not an estimate of Philadelphia earnings, for which no municipal-level published source exists. The local earned income tax is proportional, so all dollar figures for the Tredyffrin Township commute scale linearly with income and the rate comparison holds at every salary.
- Municipal taxing jurisdiction is determined by boundary rather than by postal address, and the two diverge frequently enough in Pennsylvania that the DCED lookup should be treated as authoritative for Philadelphia. Philadelphia is additionally outside this regime, administering its own wage tax on residents and non-residents under separate authority, so it does not follow the treatment described for Tredyffrin Township.
Questions people ask
Do I pay local tax twice — once where I work and once where I live?
No — you pay the higher of the two rates and never the sum. Philadelphia levies about 3.74% on residents and Tredyffrin Township levies about 0% on people who work there; whichever is larger is what you owe, and your employer withholds it.
Does working in a different town cost me anything?
Nothing extra. The tax is redirected rather than increased, so this particular crossing costs you no more than working in Philadelphia would.
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 a common enough commute to be worth modeling?
4,512 workers make it. The pairing comes from federal commuting data rather than from guesswork, and thin routes are excluded rather than estimated.
The town I work in charges nothing — does that help me?
It does not save you. Tredyffrin Township 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 basis for including this route?
Route volume is 4,512 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.
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.
