Hamilton credits only part of what Mason 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 Mason 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. Mason could take another $528 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 route from Hamilton is 4 of 5 recorded commutes into Mason, with around 614 people on it. Treat the ranking loosely. Only flows above a certain size are published at all.
  • This pairing is neutral to the worker. Mason withholds about 1.12% 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 Mason 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 Mason only up to a ceiling set as a share of income, and Mason's levy currently sits below it with $528 of annual room to spare at the reference salary. Were Mason 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.
  • Mason records 5 qualifying commuting origins in this dataset, of which Hamilton ranks 4 by worker count at approximately 614. 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 Mason and Hamilton charge you. Hamilton may then hand back what Mason took, or part of it, or none of it. Everything on this page turns on which of those it does.
  • The credit rule on this page belongs to Hamilton, not to the state. Its council sets it and its council can change it. Nothing needs to happen in Mason or at the state level for these numbers to move. Check the current rule before you rely on it.
  • This page covers city income tax only. Your school district may charge its own on top, and many in Ohio do. That one follows your address in Hamilton rather than your workplace in Mason, and it is not credited against anything.
  • One tax is on this page and it is the city one. State tax, federal tax and Social Security all still come out of your pay. None of them change when you cross the line between Hamilton and Mason. That is exactly why they are left out.
  • Every dollar amount here uses a salary of sixty thousand a year. It is a benchmark, not a guess at what people in Hamilton earn, because nobody publishes average pay for single municipalities. Scale the figures to your own salary. The rates and the credit work the same way at any income, so the Mason conclusion holds.
  • 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. Mason taxes what is earned within its boundaries, Hamilton taxes its residents on everything, and Hamilton then credits some, all or none of what Mason 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 Mason 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 Mason, 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 Mason, 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 Mason 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?

Both places charge you, but the city you live in gives back some of what the other one took. Mason taxes you for working there at about 1.12%; Hamilton then charges its own about 2% and credits part of the first against it. Whether anything is left over depends on how generous that credit is.

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.

Is this commute common enough for the numbers to mean anything?

It is a smaller route: 614 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: Mason on the basis of work location at about 1.12%, 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 614 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.
