What this commute costs you
no extra local taxUpper Uwchlan Township 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
- Live in Upper Uwchlan Township, work in Tredyffrin Township, and your local tax is your home rate: about 1%. That is $600 a year on a sixty-thousand salary. The work location adds nothing. Pennsylvania charges whichever rate is higher, and yours already is.
- Upper Uwchlan Township is one of 8 places sending workers into Tredyffrin Township, ranking 7 by size with about 547 commuters. It is Upper Uwchlan Township's 2 destination of 2.
- Residence controls this pairing: Upper Uwchlan Township levies about 1% on residents, at or above Tredyffrin Township's non-resident rate, so the outcome is the resident rate — about 1%, or $600 at the reference salary. Employers still withhold against the work location's collector, but the amount is unchanged and the residence is the ultimate recipient.
- Across 8 inflows to Tredyffrin Township tracked here, Upper Uwchlan Township ranks 7 at 547 workers, and this is that municipality's 2 destination of 2. Rate and volume are independent: a large catchment is not necessarily a high-rate one, and the two rankings frequently disagree.

What this page does not cover
- To be explicit, since the arrangement invites confusion. The rates for Upper Uwchlan Township 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.
- 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 Upper Uwchlan Township and Tredyffrin 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 Upper Uwchlan Township. No wage data exists for single municipalities, and inventing one would be worse. Scale the numbers to your own pay. The rate for the Tredyffrin Township commute is what matters, and it does not change with income.
- Two practical cautions. Postal addresses and taxing boundaries do not always agree. Your post may say Upper Uwchlan Township while your taxing municipality is a different one. Pennsylvania publishes an official lookup to settle it. The same caution applies at the Tredyffrin Township end. Philadelphia is a special case too, with its own wage tax.
- The two rates applicable to a Upper Uwchlan Township–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.
- 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 Upper Uwchlan Township–Tredyffrin 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 Upper Uwchlan Township to Tredyffrin Township differential doubles at twice the salary and halves at half of it.
- Two caveats bear on accuracy. First, postal addresses and municipal taxing boundaries diverge frequently in Pennsylvania, so a Upper Uwchlan Township address should be confirmed against the DCED municipal lookup before relying on the Upper Uwchlan 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?
No — you pay the higher of the two rates and never the sum. Upper Uwchlan Township levies about 1% 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?
Not a cent on this one. The crossing changes where the money is sent, not how much of it leaves, so your total matches a stay-at-home commute.
Which town's rate am I actually paying?
Upper Uwchlan Township 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?
547 people travel it. Volume decides whether a route gets published at all, never what the tax on it is.
The town I work in charges nothing — does that help me?
It does not save you. Tredyffrin Township takes nothing, but Upper Uwchlan Township taxes you as a resident at about 1% 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 1%) 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 547 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 1%. Residence liability is unaffected by where earnings are sourced.
