What this commute costs you
no extra local taxPhiladelphia already charges its residents more than Horsham CDP 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 Horsham CDP. The home rate is the higher of the two, and the higher one wins. That is $2,244 a year.
- This is the dearest way into Horsham CDP. Out of 3 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.
- Roughly 4,076 workers go from Philadelphia to Horsham CDP each day. That is a lot of households facing one rate question. Hence a page of its own.
- The Philadelphia to Horsham CDP commute is tax-neutral. Philadelphia's resident rate of about 3.74% is not exceeded by Horsham CDP'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.
- Of 3 routes into Horsham CDP 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.
- Approximately 4,076 employees commute from Philadelphia to Horsham CDP. 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 Horsham CDP 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.
- 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 Philadelphia and Horsham CDP. 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 Philadelphia. The local tax is a flat percentage. Scale every figure to your own salary and the Horsham CDP conclusion holds.
- Two practical cautions. Postal addresses and taxing boundaries do not always agree. Your post may say Philadelphia while your taxing municipality is a different one. Pennsylvania publishes an official lookup to settle it. The same caution applies at the Horsham CDP end. Philadelphia is a special case too, with its own wage tax.
- Workers commuting from Philadelphia to Horsham CDP 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.
- 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 Philadelphia–Horsham CDP 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 Philadelphia. The flat structure of the local tax means the Horsham CDP comparison is scale-invariant, so the rate difference rather than the dollar difference is the transferable result.
- Two caveats bear on accuracy. First, postal addresses and municipal taxing boundaries diverge frequently in Pennsylvania, so a Philadelphia address should be confirmed against the DCED municipal lookup before relying on the Philadelphia 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. Philadelphia levies about 3.74% on residents and Horsham CDP levies about 1% 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?
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?
Yes — 4,076 people make this exact journey, according to the federal employment survey that tracks where workers live against where they work. Routes below a volume floor are not published, so a page existing here means the commute is real and measured.
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 4,076 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.
