What this commute costs you
no extra local taxPhiladelphia already charges its residents more than Lower Southampton 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
- Nothing changes for this commute. A resident of Philadelphia pays about 3.74% either way. It makes no difference whether they work at home or travel to Lower Southampton Township. The home rate is the higher of the two, and the higher one wins. That is $2,244 a year.
- Lower Southampton Township is one of the main places Philadelphia sends its workers — number 6 of 69 destinations tracked, carrying about 4,458 people. This is a well-worn route rather than an unusual one.
- Roughly 4,458 workers go from Philadelphia to Lower Southampton Township each day. That is a lot of households facing one rate question. Hence a page of its own.
- The Philadelphia to Lower Southampton Township commute is tax-neutral. Philadelphia's resident rate of about 3.74% is not exceeded by Lower Southampton Township's non-resident rate, so under the state's rule the resident rate applies and the effective figure is about 3.74% — $2,244 annually at the reference salary. Withholding is remitted to the residence in full and the work location receives no share.
- This is a principal destination for Philadelphia residents: 6 of 69 tracked, carrying 4,458 workers to Lower Southampton Township. The tax outcome described above therefore applies to a substantial and stable share of that municipality's outbound commuters.
- Approximately 4,458 employees commute from Philadelphia to Lower Southampton Township. Flows of this size are why the greater-of rule matters in aggregate: the per-worker difference may be modest, but it is replicated across a large and stable population.

What this page does not cover
- A common worry, answered. You do not pay Philadelphia and Lower Southampton Township both. Only one rate applies, the higher of the two. The two councils then sort out between themselves who gets what, and your bill is unaffected.
- Only one tax is on this page. It is the local earned income tax that Philadelphia and Lower Southampton 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 Lower Southampton 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 Lower Southampton Township.
- Workers commuting from Philadelphia to Lower Southampton Township are subject to one rate, not two. The statute directs the employer to withhold the greater of the resident and non-resident rates; the allocation between the two taxing bodies is a remittance mechanic invisible to the employee. Treating the two rates as cumulative is the most common misreading of the statute.
- The scope here is the municipal earned income tax alone. State, federal and payroll taxes are unaffected by the choice between Philadelphia and Lower Southampton 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 Lower Southampton 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 Lower Southampton Township.
Questions people ask
Do I pay local tax twice — once where I work and once where I live?
The rates compete rather than stack. about 3.74% where you live, about 1% where you work, and you pay the greater of the two.
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?
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?
It is. 4,458 workers travel this pair, per the federal origin-destination survey; smaller routes fall below the publication floor and get no page.
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 4,458 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.
