What it costs you
no extra local taxHamilton credits only part of what Blue Ash takes, so the remainder is taxed twice. Solid is what you pay; the faded part of the Hamilton bar is the credit it hands back. Municipal income tax only — state, federal and payroll tax apply on top, and an Ohio school district income tax may too.
What this commute actually costs
- You can stop worrying about this one. Hamilton credits everything Blue Ash withholds, right up to its own rate of about 2%. Crossing the line to work adds nothing. Local income tax comes to $1,200 for the year, exactly as it would if the job were on your own street.
- There is room here, and it is measurable. Blue Ash could take another $450 a year from you before Hamilton's credit ran out. Until then the two cities settle it between themselves and you pay what you would have paid at home.
- This data records 6 commutes into Blue Ash, and the one from Hamilton ranks 4, carrying roughly 836 workers. That is a handful of routes rather than a full map of who works there.
- This pairing is neutral to the worker. Blue Ash withholds about 1.25% on income earned there, and Hamilton, which levies about 2% on residents, credits that payment in full without reaching its own ceiling. Liability at the reference salary is therefore $1,200 — precisely what the same earnings would attract with no commute at all. What the arrangement alters is the division of revenue between Blue Ash and Hamilton, not the sum leaving the worker's pay.
- The margin is worth knowing, because it is not large. Hamilton credits tax paid to Blue Ash only up to a ceiling set as a share of income, and Blue Ash's levy currently sits below it with $450 of annual room to spare at the reference salary. Were Blue Ash to raise its rate past that point, the excess would cease to be credited and would fall on the worker rather than on either treasury.
- Blue Ash records 6 qualifying commuting origins in this dataset, of which Hamilton ranks 4 by worker count at approximately 836. A workplace of this size draws from a small enough set of origins that the comparison is indicative rather than statistical, and the published floor excludes an unknown tail of smaller flows.

What this page does not cover
- Do not add the two rates up, and do not assume the bigger one simply wins. Neither is how Ohio works. Both Blue Ash and Hamilton charge you. Hamilton may then hand back what Blue Ash took, or part of it, or none of it. Everything on this page turns on which of those it does.
- One thing to keep in mind. Ohio does not require Hamilton to give any credit at all. That choice sits with the city, and cities revisit it. A vote in Hamilton could change what this commute to Blue Ash costs you, with no change in the law itself.
- Ohio has a second local tax that is not on this page. Some school districts levy their own income tax. It depends on where you live, not on your job in Blue Ash, and the credit from Hamilton does not touch it. If your district charges one, add it to everything here.
- These figures are the local layer alone. Whatever Hamilton and Blue Ash take sits on top of state, federal and payroll tax. Those three are the same wherever in Ohio you work, so putting them in would bury the difference this page is about.
- Sixty thousand a year is the assumption behind the dollars. It is stated rather than measured. No wage figure exists for a place the size of Hamilton. The percentages are the durable part of this page, and they do not shift with what you earn in Blue Ash.
- Two misreadings bracket the correct answer and both are common. Ohio does not simply add the two rates together, which would overstate the charge; nor does it apply only the higher of them, which is Pennsylvania's rule and would understate it wherever the credit is partial. Blue Ash taxes what is earned within its boundaries, Hamilton taxes its residents on everything, and Hamilton then credits some, all or none of what Blue Ash collected. The credit is the entire mechanism, and it is set by Hamilton rather than by the state.
- The credit rule modeled here is Hamilton's own, adopted by ordinance and amendable by Hamilton alone. Ohio's uniform framework governs definitions, filing and withholding; it does not compel any municipality to credit tax paid to another. A council vote in Hamilton can therefore change every figure on this page without anything altering in Blue Ash or in state law, which is a materially different exposure from a rate set by statute.
- Ohio school district income tax is a separate levy from municipal income tax and is excluded from these figures. It is imposed by school district of residence rather than by municipality, it is unaffected by employment in Blue Ash, and no municipal credit applies to it. A resident of Hamilton whose school district levies one owes it in addition to everything shown here, which is why the totals on this page are a municipal position rather than a complete local one.
- Only municipal income tax is modeled. Ohio's state income tax, federal income tax and payroll taxes all apply in addition and are invariant to the boundary between Hamilton and Blue Ash, which is precisely why they are excluded: isolating the layer that responds to the commute is the point of the comparison. A complete tax position requires adding them; a comparison of the two locations does not.
- Dollar figures are computed against a stated reference salary of sixty thousand rather than a municipal wage average, which no published source provides for Ohio municipalities. Both rates and the credit ceiling are proportional to income, so every figure scales linearly: the Hamilton to Blue Ash differential doubles at twice the salary and halves at half of it, and the rate relationship holds at every level. The one caveat is that whether the ceiling binds at all is itself scale-invariant here, because it too is expressed as a share of income rather than as a fixed dollar cap.
Questions people ask
Do I pay local tax twice — once where I work and once where I live?
You are taxed by both, then given credit for one. Working in Blue Ash costs about 1.25%; living in Hamilton costs about 2%, reduced by whatever share of the work tax the home city recognizes.
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.
Is this commute common enough for the numbers to mean anything?
It is a smaller route: 836 workers. That affects how representative it is, not whether the tax arithmetic applies — the rules are the same on a quiet road as a busy one.
How does a resident credit allocate liability between two municipalities?
Both jurisdictions assert a claim: Blue Ash on the basis of work location at about 1.25%, Hamilton on residence at about 2%. The residence municipality grants a credit for tax paid to the work municipality, commonly capped as a share of income. Net liability is the residence tax less that credit, floored at zero, plus the work tax.
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.
What is the measurement basis for a route of this size?
Route volume is 836 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.
