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 Pittsburgh'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
- Good news for this commute. Working in Pittsburgh costs you nothing extra. South Fayette Township charges residents about 1%, at least as much as Pittsburgh asks of people who work there but live elsewhere. The higher rate wins, so your home rate is simply the rate. That is $600 a year, wherever you work.
- Roughly 2,247 people commute from South Fayette Township to Pittsburgh, which makes this route number 17 out of 85 tracked into that workplace. A normal-sized flow rather than a dominant one.
- For the South Fayette Township to Pittsburgh commute the residence governs. South Fayette Township's resident rate of about 1% equals or exceeds Pittsburgh's non-resident rate, so Pennsylvania's greater-of test resolves to the resident rate and the effective burden is about 1%, or $600 at the reference salary. The workplace adds nothing; the entire amount is remitted to the residence. This is the majority outcome and the one most commuters need confirmed.
- This flow carries 2,247 workers, ranking 17 among 85 recorded routes into Pittsburgh and 1 of 1 destinations recorded for South Fayette Township. The rate outcome above therefore applies to a meaningful but not dominant share of that workplace's inbound commuters.

What this page does not cover
- One thing worth being clear about, because it catches people out. You are not charged by both places. South Fayette Township and Pittsburgh 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 South Fayette Township and Pittsburgh. This page is about the layer that does.
- Sixty thousand a year is a benchmark. It is not a guess at what people in South Fayette Township 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 Pittsburgh.
- Two practical cautions. Postal addresses and taxing boundaries do not always agree. Your post may say South Fayette Township while your taxing municipality is a different one. Pennsylvania publishes an official lookup to settle it. The same caution applies at the Pittsburgh end. Philadelphia is a special case too, with its own wage tax.
- Pennsylvania's local rule is a greater-of rule, not an additive one: the liability for a South Fayette Township resident working in Pittsburgh 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 South Fayette Township–Pittsburgh municipal boundary, which is precisely why they are excluded: isolating the layer that responds to the commute is the point of the comparison.
- The reference salary is a stated benchmark, not an estimate of South Fayette Township earnings, for which no municipal-level published source exists. The local earned income tax is proportional, so all dollar figures for the Pittsburgh commute scale linearly with income and the rate comparison holds at every salary.
- Two caveats bear on accuracy. First, postal addresses and municipal taxing boundaries diverge frequently in Pennsylvania, so a South Fayette Township address should be confirmed against the DCED municipal lookup before relying on the South Fayette 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?
Only once, at the higher rate. Between South Fayette Township's about 1% and Pittsburgh's about 1%, the larger governs — the two are never added together.
Does working in a different town cost me anything?
Not a cent on this one. The crossing changes where the money is sent, not how much of it leaves, so your total matches a stay-at-home commute.
Which town's rate am I actually paying?
South Fayette 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 a common enough commute to be worth modeling?
It is. 2,247 workers travel this pair, per the federal origin-destination survey; smaller routes fall below the publication floor and get no page.
Both towns charge the same — does the boundary matter at all then?
The rates match at about 1%, so the crossing moves money between authorities rather than out of your pocket.
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 basis for including this route?
Route volume is 2,247 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.
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.
