What it costs you
no extra local taxHamilton Township credits only part of what Mason takes, so the remainder is taxed twice. Solid is what you pay; the faded part of the Hamilton Township 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
- Some Ohio commutes cost you real money. This one does not. Hamilton Township gives full credit for the tax Mason takes out of your pay, so the two settle down to the same bill you would owe at home. On sixty thousand that is $1,200 for the year. The commute shifts money between city halls and leaves your total alone.
- Worth watching rather than worrying about. The credit from Hamilton Township runs out once Mason takes more than the ceiling allows, and today there is $528 a year of slack. A rate rise in Mason would eat into that first, and into your pay after.
- This route from Hamilton Township is 2 of 5 recorded commutes into Mason, with around 1,029 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 Township, 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 Township, not the sum leaving the worker's pay.
- The margin is worth knowing, because it is not large. Hamilton Township 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 Township ranks 2 by worker count at approximately 1,029. 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
- Here is the shape of it, because the arithmetic is easy to get wrong. You are taxed by both cities. What happens next is up to Hamilton Township: it may credit all of what Mason took, some of it, or none at all. That choice belongs to the city rather than to the state, which is why identical salaries in neighboring towns land so differently.
- One thing to keep in mind. Ohio does not require Hamilton Township to give any credit at all. That choice sits with the city, and cities revisit it. A vote in Hamilton Township could change what this commute to Mason costs you, with no change in the law itself.
- Watch for one more local tax. School district income tax is separate from what Hamilton Township and Mason charge, and plenty of Ohio districts levy it. Working elsewhere makes no difference to it, and no credit offsets it.
- 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 Township and Mason. That is exactly why they are left out.
- The dollar figures rest on one assumed salary, sixty thousand. Double your pay and they double. Halve it and they halve. What stays put is the relationship between what Mason charges and what Hamilton Township gives back, which is the part worth carrying away.
- 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 Township taxes its residents on everything, and Hamilton Township then credits some, all or none of what Mason collected. The credit is the entire mechanism, and it is set by Hamilton Township rather than by the state.
- The credit rule modeled here is Hamilton Township's own, adopted by ordinance and amendable by Hamilton Township 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 Township 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 Township 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 Township 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 Township 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?
You are taxed by both, then given credit for one. Working in Mason costs about 1.12%; living in Hamilton Township 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 a common enough commute to be worth modeling?
1,029 workers make it. The pairing comes from federal commuting data rather than from guesswork, and thin routes are excluded rather than estimated.
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 Township 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 basis for including this route?
Route volume is 1,029 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.
