How Much Are Property Taxes in Dublin, Ohio? 2026 Rates by District

Dublin is not one property tax rate. It is seven, spread across three counties, and they run from 49.60 mills to 69.76 mills. On a $510,000 appraised value that is $8,854 a year at the bottom and $12,452 at the top. Same city on the mailing address. A $3,599 yearly difference.

That spread is larger than the gap between Dublin and most other Central Ohio suburbs. It is the number to check before you write an offer, and it is the one most people never look at.

Here are all seven, straight from the Franklin County Auditor's tax year 2025 report and the City of Dublin's own 2026 tax guide.

How Much Are Property Taxes in Dublin, Ohio?

These are effective residential rates for tax year 2025, the bill that came due in 2026. The dollar figures apply the City of Dublin's published formula: appraised value divided by 1,000, times the rate, times 0.35.

County	District	Schools serving it	Mills	On $400,000	On $510,000	On $700,000
Franklin	273	Dublin City Schools	69.76	$9,766	$12,452	$17,091
Franklin	274	Hilliard City Schools	67.37	$9,432	$12,026	$16,506
Union	185	Dublin City Schools	62.43	$8,740	$11,144	$15,295
Delaware	10	Dublin City Schools	62.12	$8,697	$11,088	$15,219
Union	155	Hilliard City Schools	60.04	$8,406	$10,717	$14,710
Union	187	Dublin City Schools	56.70	$7,938	$10,121	$13,892
Franklin	275	Jonathan Alder Local	49.60	$6,944	$8,854	$12,152

$510,000 is the median Dublin closing in the Columbus MLS so far this year, across 1,566 sales. $400,000 is there because the City of Dublin runs that exact example in its tax guide and lands on $9,766, which is what the formula above produces. The two sources agree to the dollar on all three Franklin districts.

One thing the table does not show. These are the rates before the owner-occupancy and non-business credits, which is how both the auditor and the city publish them. Your actual bill comes in under these figures if the home is your primary residence. More on that below, because it changes next year.

Why Does Dublin Have Seven Different Tax Rates?

Because a tax rate is a stack, not a decision made by the city.

Your bill is the sum of every entity whose boundary crosses your parcel: the county, the township, the school district, the vocational district, the library, the parks, the zoo. The City of Dublin collects roughly 3 percent of what you pay. The school district collects the large majority. In district 273 the city's own breakdown puts Dublin City Schools at $6,341 of a $9,766 bill, which is 64 percent, against $262 for the City of Dublin itself.

So the question that sets your bill is not "am I in Dublin." It is "which school district, in which county, in which township." Dublin's boundary crosses Franklin, Delaware and Union counties. Three school districts serve pieces of it: Dublin City, Hilliard City, and Jonathan Alder Local. Multiply those out and you get seven live combinations.

The 20 mill gap between district 273 and district 275 is almost entirely school millage. Jonathan Alder Local sits on a much lighter levy stack than Dublin City Schools. That is a statement about voted millage and nothing else. Anyone comparing districts should pull the Ohio Department of Education report card for the specific buildings a parcel is assigned to and confirm assignment with the district, because boundaries move and the auditor's district code is a tax boundary, not an enrollment guarantee.

Jerome Village, the large build-out north of Hyland Croy Road, sits in Jerome Township in Union County and is served by Dublin City Schools. If you are shopping new construction on the Dublin side, that is a Union County parcel with a Union County rate, not a Franklin County one. It is a common mix-up and it moves the number by real money.

Do You Pay More Property Tax in Dublin or Westerville, Ohio?

Dublin. At the same appraised value, for the main district in each city.

Franklin County's tax year 2025 report puts City of Dublin with Dublin City Schools at 69.76 effective residential mills. City of Westerville comes in at 63.59. That is 6.17 mills, and on a $510,000 appraised value it works out to about $1,102 more per year in Dublin. On $700,000 it is about $1,513.

I am flagging this because the assumption runs the other way. Buyers tell me constantly that Dublin is the tax bargain of the two. At equal appraised value it is not. The two cities do carry different price levels, so the same budget buys a different house in each. The median Westerville closing this year is $430,000 against Dublin's $510,000. The bill you write depends on the value of the specific parcel, not on a rate comparison in the abstract. Run both on a real address before you let either number steer a decision. The Westerville submarket page and the Dublin page have the current inventory side by side.

Neither city is one rate, either. Westerville has its own district spread. So does every suburb in the county, which is the point of the Franklin County rate breakdown.

How Do You Find Your Actual Dublin Tax District?

Four steps. It takes about five minutes and it is the only number worth trusting.

1. Get the parcel number. It is on the listing detail, in the MLS, or searchable by address on the county auditor's site. Franklin County parcels start with a three digit prefix, and Delaware and Union have their own formats.
2. Pull the parcel record on the correct county auditor's site. Franklin County is at franklincountyauditor.com, Delaware at delawarecountyauditor.org, Union at unioncountyohio.gov. The City of Dublin lists all three in its tax guide because it has to.
3. Read the taxing district code off the record and match it to the table above. The record also shows the auditor's appraised value, which is the number the formula uses. It is not the sale price and the two can sit far apart.
4. Take the current annual tax off the record and divide by 12. Compare that to the figure your lender used in pre-approval. If they differ by more than $100 a month, call the loan officer before the financing contingency clock runs, not after.

That last step is where deals get uncomfortable. A lender quoting a county average rather than the parcel can be off by hundreds a month in either direction, and on a Dublin price point the miss compounds fast. I pull the parcel record on every offer I write for exactly this reason, and I would rather find a bad number in week one than at the closing table.

If the appraised value on the record looks wrong against what the house is worth, that is appealable. The process and the deadline are in the Central Ohio property tax appeal guide.

What Changes on Your Ohio Tax Bill in 2027?

The credit side, and it is a real change.

Ohio has long applied two rollbacks to residential property: a 10 percent non-business credit and a 2.5 percent owner-occupancy credit, 12.5 percent combined for an owner-occupied home. House Bill 186 rewrites both, starting with tax year 2026, which is the bill you pay in 2027.

The Legislative Service Commission analysis of the bill states it "modifies the 10% and 2.5% property tax rollbacks for residential property, with the effect that the total rollback for owner-occupied homes will increase, from 12.5% to 15.38%, and the rollback for all other residential property will be eliminated."

Two things follow from that sentence.

If Dublin is your primary residence, your credit goes up. Modestly, phased in over four years, but up.

If you own a Dublin rental, a second home, or a property held in an entity, the non-business credit goes away over the same period. On a district 273 parcel at a $510,000 appraised value, losing 10 percent of the bill is roughly $1,245 a year once the phase-out completes. That is a line item worth putting in the model now rather than discovering it on a statement.

The bill also creates an inflation cap credit tied to the 20 mill floor, which is aimed at limiting how fast unvoted school millage can grow with values. That one is more complicated and it is administered by the county auditor, so the effect on a specific parcel shows up on the bill rather than in a rate table.

What Should You Do Before You Write an Offer in Dublin?

Three things, in this order.

1. Confirm the district code on the parcel, not the city on the sign. Seven rates, 20 mills of spread, and the mailing address tells you nothing.
2. Use the auditor's appraised value in the math, not the list price. Ohio taxes 35 percent of appraised value, and after a purchase the county gets to revisit that value on its own cycle.
3. Ask the listing agent for the most recent special assessment statement if the home sits in a community development district. Those assessments are billed alongside the tax and they do not appear in the millage table at all. In newer Dublin corridors they can run well into four figures a year.

None of this is exotic. It is a parcel lookup and one piece of arithmetic, and it is the difference between a payment you planned for and a payment that arrives in escrow twelve months later.

If you are weighing a specific Dublin address, send me the address and I will pull the parcel record and the district rate before you write anything. If you are on the sell side, the same lookup tells you what a buyer is going to find when they do their homework. Better you see it first. You can also start with a current value read on your own home.
