What this commute costs you
no extra local taxPittsburgh already charges its residents more than South Fayette 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 Pittsburgh pays about 3% either way. It makes no difference whether they work at home or travel to South Fayette Township. The home rate is the higher of the two, and the higher one wins. That is $1,800 a year.
- This is a thin route. Only about 519 people travel from Pittsburgh to South Fayette Township, ranking it 22 of 23 destinations. The rule is the same as anywhere, but far fewer people meet it here.
- The Pittsburgh to South Fayette Township commute is tax-neutral. Pittsburgh's resident rate of about 3% is not exceeded by South Fayette Township's non-resident rate, so under the state's rule the resident rate applies and the effective figure is about 3% — $1,800 annually at the reference salary. Withholding is remitted to the residence in full and the work location receives no share.
- This is a minor flow: 519 workers, ranking 22 of 23 destinations recorded for Pittsburgh. The rate treatment is identical to that on larger routes; only the affected population differs, and it is small.

What this page does not cover
- To be explicit, since the arrangement invites confusion. The rates for Pittsburgh and South Fayette Township 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.
- Only one tax is on this page. It is the local earned income tax that Pittsburgh and South Fayette Township levy. State tax, federal tax and Social Security all still apply. All three are the same wherever in Pennsylvania you work.
- All the dollar amounts rest on one assumed salary. It is stated rather than measured, because nobody publishes average pay for Pittsburgh. The local tax is a flat percentage. Scale every figure to your own salary and the South Fayette Township conclusion holds.
- Two practical cautions. Postal addresses and taxing boundaries do not always agree. Your post may say Pittsburgh while your taxing municipality is a different one. Pennsylvania publishes an official lookup to settle it. The same caution applies at the South Fayette Township end. Philadelphia is a special case too, with its own wage tax.
- The two rates applicable to a Pittsburgh–South Fayette Township 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.
- The scope here is the municipal earned income tax alone. State, federal and payroll taxes are unaffected by the choice between Pittsburgh and South Fayette Township and are therefore outside the model. A total tax position requires adding them; a comparison of the two locations does not.
- Monetary figures derive from a single stated salary assumption; no published wage series covers Pennsylvania municipalities such as Pittsburgh. The flat structure of the local tax means the South Fayette Township 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 Pittsburgh address should be confirmed against the DCED municipal lookup before relying on the Pittsburgh 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. Pittsburgh levies about 3% on residents and South Fayette Township 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 Pittsburgh would.
Which town's rate am I actually paying?
Pittsburgh'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?
519 workers make this journey — enough to be published, but not a major corridor. The tax rules do not depend on how many people travel a route, so the figures hold regardless; the count only tells you how typical this pairing is.
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%) 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 519 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.
