A buyer comparing two nearly identical listings in Westerville, both listed at roughly the same price, both a five-minute drive from Uptown State Street, might assume the only real difference is the kitchen counters. It isn't. One of those houses could sit inside the actual City of Westerville, subject to the city's own income tax and its own police and parks budget. The other could sit in an unincorporated township that shares Westerville's post office, its schools, and even its street grid, but answers to a completely different government and a completely different tax bill.
This isn't a hypothetical edge case. It's built into how Central Ohio grew.
The Name on the Listing Isn't the Government on the Bill
The City of Westerville's own income tax office says it outright on its website: a resident's mailing address, post office, or school district "does not always reflect the taxing jurisdiction in which you live." That's a government agency telling its own residents not to trust the label on their envelope.
Here's what's actually being collected if a parcel sits inside city limits. Westerville levies a 2.0 percent municipal income tax, in place since January 1, 2016, split into four dedicated pieces under the city code: a half percent for general operations and capital improvements, a half percent for police and street maintenance, a quarter percent earmarked specifically for parks and recreation, and three-quarters of a percent for general services and street work. That's a real, itemized budget funding real things a homeowner uses every week, from snowplows to the rec center.
None of that applies if the parcel isn't actually inside the city.
The Islands Around the City
Blendon Township is the reason this gets confusing. It's an unincorporated township in Franklin County that has been carved down over decades of annexation into a scattered set of pockets, some large, some tiny, mostly surrounded by Westerville and Columbus. A home with a Westerville mailing address can sit in one of these Blendon Township pockets and never pay the city's 2.0 percent income tax at all, because it isn't legally part of the city.
The township itself doesn't hide the difference. Its own resident FAQ states plainly that Blendon Township and Westerville "pay different taxes," which is why the township prices things like park shelter rentals differently for its own residents versus everyone else. It's the kind of line that only shows up once you're already living there and trying to book a picnic shelter.
That distinction used to be softened a little. Until January 1, 2022, Blendon Township ran a reimbursement program that helped offset the cost of Westerville amenities for township residents who couldn't use city services as a matter of right. That program ended. The boundary between "in the city" and "next to the city" got a little sharper, not softer, in the last few years.
Cross into Delaware County on the north side of Westerville and there's a second township doing the same thing under a different name: Genoa Township. Same idea, different jurisdiction, its own separate levies for fire and police that show up on a homeowner's tax bill with zero connection to anything the City of Westerville budget funds. Genoa Township voters have had fire levy questions on the ballot repeatedly in the past couple of years, and those votes move a Genoa Township tax bill up or down independent of whatever the city is doing three miles south.
Cross the County Line and the Auditor Changes Too
Even for parcels that are unambiguously inside Westerville city limits, there's a second layer of overlap: the city itself straddles Franklin and Delaware counties. That means two homes both fully inside the City of Westerville, both paying the same 2.0 percent municipal income tax, can still be assessed by two entirely different county auditor's offices with two different reappraisal cycles and two different sets of school and levy stacking.
As of 2026, effective property tax rate data shows a real gap between the two sides. On the Franklin County side of Westerville, the median effective property tax rate runs close to 1.99 percent, with individual zip codes ranging from roughly $5,635 to as much as $12,254 depending on which school levies and assessment districts stack on that parcel. On the Delaware County side, the median effective rate sits closer to 1.81 percent, with a tighter zip-level range of about $6,729 to $7,888. The Delaware County side isn't uniformly cheaper. It's just a narrower spread, while the Franklin County side has a much wider gap between its low and high end.
That spread matters more than the median. A buyer comparing two similarly priced Westerville homes on opposite sides of the county line shouldn't assume the tax bill will land in the same place just because the sale price does.
Why the Boundary Is Still Being Drawn
This isn't old history that stopped mattering. Westerville and Blendon Township have run a Joint Economic Development Zone since 2013, an arrangement that lets the city and the township coordinate on business tax revenue without the township giving up its independence or getting annexed outright. That structure is still active enough that it's now being used as a template elsewhere in the county. A hyperlocal Westerville news outlet reported in late August 2026 that Harlem Township, further north in Delaware County, is negotiating a similar cooperative agreement with the Village of Galena, explicitly modeled on the long-running Westerville-Blendon arrangement. Local officials are still choosing, right now, to keep these boundaries as separate, cooperating governments rather than merging them.
For a buyer, that means the current patchwork isn't a leftover quirk waiting to be cleaned up. It's a deliberate, ongoing approach to how Central Ohio suburbs grow, and it's likely to keep producing addresses that share a name but not a government.

What to Verify Before You Write the Offer
A listing sheet won't sort any of this out. Before assuming what a Westerville-area home actually costs to own, it's worth confirming a few things directly:
- Pull the parcel on the Franklin County Auditor or Delaware County Auditor site to confirm which county is actually assessing the property, not just which one seems geographically obvious.
- Call the Westerville Income Tax Division directly to confirm whether the specific address falls inside city limits or in an adjacent township. They offer this lookup by phone precisely because the mailing address won't answer it.
- Ask whether the parcel is in a township, and if so, which one, since Blendon Township and Genoa Township have different zoning processes, different trash contracts, and no shared claim on Westerville's park and recreation amenities.
- Treat the school district as its own, separate question. It follows neither the city limit nor the county line, so verifying school assignment is a fourth check, not something answered by the first three.
FAQ
Does a Westerville mailing address guarantee I'll pay Westerville's city income tax? No. The address only reflects the postal service area. Whether the 2.0 percent tax applies depends on whether the parcel sits inside the legal city limits, which a Westerville Income Tax Division lookup can confirm.
If I live in Blendon Township but work at a job physically inside Westerville, do I pay the city income tax? Non-residents working inside Westerville can owe the city's tax rate on income earned there, separate from whatever their home township charges or doesn't charge. It's worth confirming withholding directly with the city's tax office rather than assuming based on where you live.
Does the county a Westerville home sits in affect anything besides property tax administration? It can also affect voter precincts, court jurisdiction, and which county's auditor and treasurer offices a homeowner deals with for appeals or payment questions, on top of the effective tax rate differences already covered above.
None of this shows up on a comp sheet, and it's exactly the kind of detail that's easy to miss until a closing statement or a first tax bill surprises someone. If you're comparing homes across Westerville's overlapping city, township, and county lines and want someone to help sort out which government actually applies to a specific address, Ayana Realty Group works this market every day and can walk through it parcel by parcel before you write an offer.
