What this commute costs you
no extra local taxThe two rates are identical, so the test is a wash — but this pair sits exactly at the line, and any rise in Horsham CDP's commuter rate would start costing you. 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 Warminster Township, work in Horsham CDP, 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.
- Good position on this one. Across 3 routes into Horsham CDP in this data, Warminster Township has the lowest local rate of the lot. Everyone else commuting to the same place pays more.
- Residence controls this pairing: Warminster Township levies about 1% on residents, at or above Horsham CDP'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.
- Of 3 inflows to Horsham CDP tracked here, this route produces the lowest effective local rate. Local earned income tax attaches to residence and workplace rather than to the employer, so identical roles at one workplace carry different burdens and this residence sits at the favorable end.

What this page does not cover
- To be explicit, since the arrangement invites confusion. The rates for Warminster Township and Horsham CDP 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 Warminster Township 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 Warminster Township. 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 Warminster Township 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.
- The two rates applicable to a Warminster Township–Horsham CDP 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 Warminster Township–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 Warminster Township. 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 Warminster Township address should be confirmed against the DCED municipal lookup before relying on the Warminster 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. Warminster Township levies about 1% 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?
Nothing extra. The tax is redirected rather than increased, so this particular crossing costs you no more than working in Warminster Township would.
Which town's rate am I actually paying?
Warminster Township's, because it is the higher of the two. Where you live sets the rate on this route, so working across the boundary does not raise what you owe — it only changes who collects it.
Is this commute common enough for the numbers to mean anything?
538 people travel it. Volume decides whether a route gets published at all, never what the tax on it is.
Both towns charge the same — does the boundary matter at all then?
Not to your total. Warminster Township and Horsham CDP both levy about 1%, so the amount is settled either way — what the boundary decides is which authority receives it, and that is an accounting question rather than a cost to you.
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 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 measurement basis for a route of this size?
Route volume is 538 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 identical rates either side of the boundary?
Both jurisdictions levy about 1%, so the governing rate is identical regardless of which rule allocates it. The boundary affects revenue attribution between authorities, not employee liability.
