In Dublin, Ohio, the Lower Tax Rate Can Still Mean the Bigger Bill

Two homeowners in Dublin, one in zip code 43017 and one in 43016, will pay different property tax rates this year. The homeowner in 43017 carries the higher rate, close to 2.00 percent. The homeowner in 43016 pays something closer to 1.83 percent. On paper, 43016 looks like the better deal.
It isn't. Median annual tax bills in 43016 run closer to $17,227, against roughly $11,603 in 43017. The zip code with the lower rate produces the bigger check, because home values in 43016 run high enough (a median near $924,200) to overwhelm the rate advantage. A buyer comparing "Dublin" tax rates on a spreadsheet and picking the smaller number would have picked the more expensive address.
That inversion is the whole story of buying in Dublin. The city reads as one market on a portal search. It isn't one market once you look at the parcel. Dublin's boundary runs through Franklin, Delaware, and Union counties, and the school assignment, the tax rate, and soon the school building itself can all change within the same subdivision, sometimes within the same block.
Effective tax rate and total tax bill measure two different things, and Dublin is a useful place to watch them pull apart. Rate tells you the percentage. Bill tells you the dollar amount once that percentage lands on an actual home value. In most cities the two move together closely enough that nobody bothers separating them. In Dublin, the zip code split shows they can move in opposite directions, driven by how much more the land and structure are worth on one side of the line.
For a buyer comparing two listings at similar list prices in different sections of Dublin, this means the tax line on a closing disclosure needs to be pulled for the specific parcel, not estimated from a citywide average. A rate that looks favorable on a comparison chart can still produce a bigger monthly escrow number once it's applied to that section's typical home value.
The rate variation traces back to which county is actually collecting the money. Dublin's slice of Delaware County carries that county's highest effective tax rate at 2.00 percent, well above Delaware County's low end in places like Centerburg, where the rate runs closer to 1.13 percent. Dublin's slice of Franklin County runs its own separate rate, close to 1.94 percent, which sits about 32 percent above the Franklin County average of 1.47 percent.
Put plainly: Dublin is the expensive pocket in both counties it touches. It is not, however, the same expensive number in both. A Dublin address in Franklin County and a Dublin address in Delaware County are answering to two different county auditors, two different sets of school levies, and two different reappraisal schedules. Union County adds a third layer again, built around townships like Jerome Township rather than a city-level rate comparable to the other two.
None of this shows up on a listing photo. It shows up on the parcel record.
This isn't an abstract boundary problem confined to a map nobody looks at. It runs through recognizable Dublin geography.
Muirfield Village, the golf community Jack Nicklaus founded and the annual host of the PGA Tour's Memorial Tournament, sits in the section of Dublin where county and school lines have historically required a parcel-by-parcel check rather than a neighborhood-wide assumption. Ballantrae, a well-established Dublin subdivision, includes homes zoned into Hilliard City Schools rather than Dublin City Schools, despite the Dublin address. Washington Elementary, built there in 2007, was the first Hilliard City Schools building ever constructed inside Dublin's limits. Jerome Village, one of the newer large developments on Dublin's western edge, sits in Union County, where the tax structure runs differently from the Franklin County core of the city.
A buyer working from the assumption that a Dublin address guarantees Dublin City Schools, or that every Dublin subdivision answers to the same auditor, is working from a map that doesn't match the actual jurisdiction lines on the ground.
Ohio passed property tax reform that reshapes two credits homeowners see on their bill. For tax year 2026 bills, the nonbusiness credit drops to 7.5 percent, while the owner-occupancy credit rises to 5.7 percent, up from 2.5 percent. The nonbusiness credit continues phasing down until it disappears entirely on tax year 2029 bills, except for agricultural land, at which point the owner-occupancy credit reaches 15.38 percent. The Delaware County Auditor laid out these changes directly, and the Delaware Gazette covered the same statement in February.
A separate piece of that same reform matters more for anyone specifically comparing Dublin to its immediate neighbors. On the most recent tax bill cycle, homeowners in the Big Walnut, Buckeye Valley, and Delaware City school districts received an added inflation tax credit. Homeowners in the Dublin, Olentangy, and Westerville school districts did not, because those three districts were not sitting at the state's 20-mill floor during the 2023 reappraisal. The floor is a protection mechanism for school funding. Districts above it don't trigger the same relief valve districts at the floor do.
The practical version: a homeowner in a neighboring Delaware County district might see a credit line on their bill that a Dublin homeowner, in a district carrying comparable value growth, simply won't see. It isn't a billing error. It's a structural feature of which side of the floor a given school district happens to sit on, and it has nothing to do with what the two houses are actually worth.
Dublin City Schools covers 47 square miles across Dublin, Columbus, Hilliard, and Upper Arlington, spanning Franklin, Delaware, and Union counties. More than 40 percent of the district's own students live outside Dublin's city limits. The district is also projected to add roughly 270 students a year through 2032, which is the kind of growth that eventually forces a boundary redraw.
That redraw is already scheduled. Dublin City Schools has confirmed that attendance boundaries are changing starting with the 2027-2028 school year, and the district has flagged that third-party sites may still be showing the boundaries as they stood before the change. For a family buying now with school assignment as a deciding factor, the honest answer for any specific address is the one that comes from the district's own locator tool at the time of the move, not from a boundary map that was accurate two years ago.
None of this argues against Dublin. It argues against treating "Dublin" as a single line item. The city's median price tells a buyer what a typical home costs. It tells them nothing about which auditor is billing them, which credit did or didn't apply this cycle, or which elementary school a specific parcel feeds into two years from now. Those answers live at the parcel level, and in a city built across three counties, the parcel level is where the real comparison has to happen.
Does a Dublin address guarantee Dublin City Schools? No. Subdivisions like Ballantrae include homes zoned into Hilliard City Schools despite carrying a Dublin address. School assignment should be confirmed for the specific parcel, not assumed from the city name.
How do I find the actual tax rate for one specific Dublin address? The rate and current bill are tied to the parcel and the county collecting it. Franklin County and Delaware County each maintain auditor tools that return the exact figure for a given parcel number, which is the only reliable way to compare two specific addresses rather than two citywide averages.
Will the 2026 credit changes lower everyone's bill the same amount? No. The owner-occupancy credit increase and nonbusiness credit phase-out apply differently depending on how a property is used, and the separate inflation credit only applied to districts that were already at the 20-mill floor. Dublin, Olentangy, and Westerville districts did not qualify for that piece.
If you're comparing a specific Dublin address against another suburb, or weighing two sections of Dublin against each other, the tax bill and school assignment are worth confirming at the parcel level before the number on a listing sheet becomes the number on your closing disclosure.
