What this commute costs you
no extra local taxPhiladelphia already charges its residents more than West Conshohocken 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
- Live in Philadelphia, work in West Conshohocken Borough, and your local tax is your home rate: about 3.74%. That is $2,244 a year on a sixty-thousand salary. The work location adds nothing. Pennsylvania charges whichever rate is higher, and yours already is.
- Few other routes into West Conshohocken Borough appear in this data, so there is little to compare at that end. The other direction has plenty. Philadelphia sends workers to 69 places, and this is number 33 by size.
- Residence controls this pairing: Philadelphia levies about 3.74% on residents, at or above West Conshohocken Borough's non-resident rate, so the outcome is the resident rate — about 3.74%, or $2,244 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.
- West Conshohocken Borough draws few recorded inflows, so cross-origin comparison is thin at the destination end. The origin is better covered: Philadelphia appears as the home municipality for 69 tracked destinations, of which this ranks 33 by worker count.

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 West Conshohocken 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.
- Only one tax is on this page. It is the local earned income tax that Philadelphia and West Conshohocken Borough levy. State tax, federal tax and Social Security all still apply. All three are the same wherever in Pennsylvania you 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 West Conshohocken Borough commute is what matters, and it does not change with income.
- 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 West Conshohocken Borough.
- Pennsylvania's local rule is a greater-of rule, not an additive one: the liability for a Philadelphia resident working in West Conshohocken 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.
- The scope here is the municipal earned income tax alone. State, federal and payroll taxes are unaffected by the choice between Philadelphia and West Conshohocken Borough and are therefore outside the model. A total tax position requires adding them; a comparison of the two locations does not.
- 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 West Conshohocken Borough differential doubles at twice the salary and halves at half of it.
- 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 West Conshohocken Borough.
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 West Conshohocken Borough's about 1%, the larger governs — the two are never added together.
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?
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?
1,221 workers make it. The pairing comes from federal commuting data rather than from guesswork, and thin routes are excluded rather than estimated.
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 basis for including this route?
Route volume is 1,221 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.
