What this commute costs you
workplace governsPhiladelphia charges commuters more than Northampton Township charges its own residents, so the work rate wins the greater-of test and the difference is real money. 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

What this page does not cover
- One thing worth being clear about, because it catches people out. You are not charged by both places. Northampton 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 Northampton Township and Philadelphia. This page is about the layer that does.
- All the dollar amounts rest on one assumed salary. It is stated rather than measured, because nobody publishes average pay for Northampton Township. The local tax is a flat percentage. Scale every figure to your own salary and the Philadelphia conclusion holds.
- A postal address in Northampton Township 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 Philadelphia.
- Pennsylvania's local rule is a greater-of rule, not an additive one: the liability for a Northampton 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 Northampton 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.
- Monetary figures derive from a single stated salary assumption; no published wage series covers Pennsylvania municipalities such as Northampton Township. The flat structure of the local tax means the Philadelphia comparison is scale-invariant, so the rate difference rather than the dollar difference is the transferable result.
- 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 Northampton Township. 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 Philadelphia.
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 Northampton Township's about 1% and Philadelphia's about 3.43%, the larger governs — the two are never added together.
What does crossing this boundary actually cost me?
About $1,458 a year. That is the gap between this commute and an identical job in Northampton Township, and it exists purely because the boundary sits between them.
Which town's rate am I actually paying?
Philadelphia's, because it is the higher of the two. Where you work sets the rate on this route, and your home town receives its share out of what is collected rather than charging you separately.
Is this a common enough commute to be worth modeling?
2,300 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 1%) 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 $1,458 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 2,300 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.
