The New Ohio Property Tax Credit Has A Westerville-Shaped Hole In It

Ohio homeowners have been hearing about a property tax break all year. State lawmakers passed a package of five bills at the end of 2025 aimed at slowing down runaway tax bills, and the centerpiece, House Bill 186, created something called the Inflation Cap Credit. It shows up as a line item on second-half 2026 tax bills, and for a lot of Ohio homeowners, it means a smaller check this summer than they expected.

If you own property in the Westerville City School District, that line item will not appear on your bill. Not because of an oversight, and not because Westerville residents were left out of the negotiations. It is because Westerville's tax structure works differently than the districts around it, and understanding why tells you something useful about how this suburb's tax bill will behave going forward, independent of what happens to home prices.

The Credit That Isn't Coming

House Bill 186 became effective March 20, 2026, though its retroactive provisions apply to tax year 2025 bills payable this year. The mechanics are specific: the credit only applies to school districts sitting at what Ohio calls the 20-mill floor, a constitutional guarantee that keeps a district's operating levy from being reduced below 20 mills even as property values climb and the standard reduction factor would otherwise push the rate lower.

Delaware County Auditor George Kaitsa put the local implications in writing twice this year, first in a January 16, 2026 statement and again in a February 17, 2026 piece in the Delaware Gazette. Taxpayers in the Big Walnut, Buckeye Valley, and Delaware City school districts would see the inflation credit on their second-half 2026 bill. Taxpayers in the Olentangy, Dublin, and Westerville school districts would not, because those three districts were not at the 20-mill floor during the 2023 reappraisal. Hoodline confirmed the same list in a June 17, 2026 report on the county's implementation timeline, which also pushed the second-half due date to August 17, 2026 while auditors recalculated parcel by parcel.

Why The Floor Decides Who Gets Paid Back

The credit exists to refund something specific. In districts sitting at the 20-mill floor, the standard reduction factor that normally offsets rising property values cannot push the rate any lower, so when a county reappraisal drives values up, those districts see an automatic, unvoted tax increase. Public comments from this year's Delaware County auditor race put that increase at 15 to 17 percent for districts caught at the floor during a recent reappraisal. HB 186 was built to cap that specific spike at the rate of inflation and refund the difference.

Westerville never had that spike to refund. The district's operating levies were still high enough above 20 mills that the ordinary reduction factor, the one Ohio has used since House Bill 920 in 1976, kept doing its job as valuations rose. No floor was hit, so there was no automatic overcharge, and there is nothing for the new credit to reimburse.

That is a meaningfully different situation from getting excluded out of neglect. It says Westerville's operating levies are running with more room between them and the floor than Big Walnut's or Buckeye Valley's, which in turn reflects a district that has needed higher voted millage to fund a larger, faster growing student population.

What Room Above The Floor Actually Means For A Buyer

The practical consequence is about what drives future tax movement in each district, not just which line item appears on the 2026 bill. In a floor district, the next reappraisal cycle can trigger another automatic increase regardless of what happens at the ballot box, because the floor mechanism overrides the normal reduction factor. In Westerville, that lever isn't in play. Tax growth here comes from what voters approve, not from a structural quirk in how the floor calculation resets.

That distinction has already played out in public view. Westerville City Schools placed a 4.9-mill operating levy and a 1.66-mill bond issue on the November 2024 ballot. It failed. The district returned in November 2025 with an earned income tax measure instead, which voters approved. Whatever happens to Westerville's tax bill over the next several years will trace back to decisions like that one, made at the ballot, rather than to an automatic recalculation tied to the 20-mill floor.

For a buyer comparing Westerville against a Big Walnut-area home a few miles up Sunbury Road, this matters more than the current bill amount. A floor district's tax bill can move on its own during a reappraisal year, then get partially refunded through a mechanism like the Inflation Cap Credit. A non-floor district's tax bill moves when residents vote to raise it, and stays flat otherwise. Neither structure is better or worse on its face, but they carry different kinds of uncertainty, and a buyer weighing carrying costs over a five or ten year hold should know which one applies to the district they're considering.

The County Line Complicates The Picture Further

Westerville's tax story has one more layer that neighboring floor districts don't share. Testimony from the district's own Treasurer and CFO to Ohio Senate committees in 2025 confirmed that Westerville City Schools sits in both Franklin and Delaware counties and serves close to 15,000 students across multiple municipalities. That split means the same school district, and the same non-floor status, gets administered by two separate county auditors, each running its own reappraisal schedule and its own billing calendar.

The disruption from HB 186's rollout showed that split plainly this year. Delaware County pushed its second-half due date to August 17, 2026 while it finished recalculating credit eligibility parcel by parcel. Franklin County's treasurer told local news its own second-half bills would go out no later than June 26, 2026, with a July 20 due date, while flagging its own processing errors tied to the same law. Two homes in the same school district, a few miles apart, ended up on different billing timelines this year because of which county auditor's office they fall under, on top of already sitting outside the 20-mill floor conversation entirely.

What This Means If You're Comparing Suburbs

None of this shows up on a portal listing. A search for homes in Westerville returns a median sale price, in the neighborhood of $490,000 over the three months ending June 2026 based on multiple listing service data, and nothing about which side of the 20-mill floor the school district sits on. Columbus REALTORS reported 133 closed sales in the Westerville City School District in June 2026, up 23.1 percent year over year, a pace that outstripped the region's broader 5.0 percent gain that same month. The market is moving fast enough that most buyers never slow down to ask why their prospective tax bill looks different from a neighbor's a few school districts over.

The answer, this year, is that Westerville isn't getting a credit its neighbors are getting, and the reason has more to do with how the district has been funded for years than with anything happening in 2026. That's worth knowing before you're comparing a listing here against one in Sunbury or New Albany, because the number on the closing disclosure isn't just a snapshot. It's a reflection of which side of a structural line the property sits on, one that predates this year's legislation and will keep shaping how the bill moves long after the current news cycle passes.

Frequently Asked Questions

Does this mean Westerville residents are paying more in property taxes than Big Walnut residents? Not necessarily. The credit only refunds an increase that happened because of the 20-mill floor mechanism. Westerville wasn't at the floor, so it didn't get that specific automatic increase to refund. It says nothing about the overall bill size, only about which mechanism is driving future changes.

Will Westerville's tax bill go up because of HB 186? HB 186 itself doesn't raise Westerville's bill. The district's future tax movement will continue to come from voter-approved levies and bond issues, the same way it has for years, rather than from the floor recalculation that triggers the new credit elsewhere.

Does the Franklin and Delaware County split change what I owe if I buy in Westerville? It changes which auditor's office bills you and on what calendar, which mattered a great deal in 2026 given the two counties' different HB 186 rollout timelines. It does not change which school district levies apply, since Westerville City Schools serves both sides of that line.

Should I ask about school district tax status before making an offer? It's a reasonable question to raise with your agent or the seller's disclosure packet, particularly if you're comparing a Westerville property against one in a neighboring floor district. It won't change the sale price, but it will shape what you can expect from the tax line on future bills.
