A home with a Westerville mailing address isn't necessarily inside the City of Westerville. The area around the city also includes parts of Columbus and unincorporated Genoa and Blendon townships, and each one has its own rules. The City of Westerville says it plainly: "Your mailing address, i.e. area post office or school district does not always reflect the taxing jurisdiction in which you live."
That one line decides who supplies your electricity, who bills your water and trash, and whether you owe a city income tax on wages earned at home. For buyers comparing two similar listings, the income tax often matters less than people expect, and the utility setup matters more.
For a Columbus commuter, the income tax mostly evens out
Start with how the credits work, because they cancel out most of the difference.
The City of Westerville says its municipal income tax is 2.0%. A resident who works somewhere else pays tax to the city where they work. Westerville then "allows full credit up to our 2.0% rate." The City of Columbus says residents owe 2.5% on income wherever it's earned and get a 100% credit for tax paid to another city, capped at 2.5%. Ohio Revised Code section 718.04 gives income-tax authority to municipal corporations, not to townships as a general residential tax.
Westerville's tax office sums up the order this way: "Local tax is due first to the city in which the income was actually earned and secondarily to your city of residence, based on their laws."
Here is what those published rules mean for three households, each with a Westerville mailing address:
| Where you live | Commute to a Columbus job (2.5%) | Work at an office inside Westerville (2.0%) | Work fully from home |
|---|---|---|---|
| City of Westerville | 2.5% to Columbus, nothing more to Westerville | 2.0% to Westerville | 2.0% to Westerville |
| City of Columbus portion | 2.5% to Columbus | 2.0% to Westerville, plus 0.5% to Columbus | 2.5% to Columbus |
| Unincorporated Genoa or Blendon Township | 2.5% to Columbus | 2.0% to Westerville | No general township residential tax |
The first column holds the main point for commuters. If your paycheck comes from a Columbus job, you pay the same municipal rate whichever side of the line your house is on. Columbus taxes the wages where you earn them, and Westerville's credit covers everything it would otherwise charge.
This is general information drawn from the cities' published rules, not tax advice. Your own return depends on your income sources and filing details.
Where the city line does change the math
The gap opens up in the last column. According to McDonald Hopkins, under Ohio's ordinary rules, municipal tax follows where the work is actually done. The COVID-era rule that let employers keep withholding for the old office location was extended only through December 31, 2021. From January 1, 2022, Ohio went back to the traditional 20-day withholding rule. That rule controls when an employer has to withhold. It doesn't make work done in a city tax-free.
For someone who works from home every day, the home's jurisdiction becomes the work location. On $90,000 of wages, the arithmetic looks like this:
- City of Westerville home: 2.0%, or $1,800
- Columbus-portion home: 2.5%, or $2,250
- Unincorporated township home: no general municipal residential tax
There is one catch for township addresses. Blendon Township says the Blendon-Westerville JEDZ, a joint economic development zone, has charged 2% since February 1, 2013. It applies to businesses inside the zone and to people who work at those businesses, not to every Blendon Township address. Westerville's tax office handles JEDZ filings, which is part of why the two get mixed up.
A household with one commuter and one remote worker could see no difference on the first paycheck and a real one on the second. Ask each earner where they'll actually work before treating two listings as equal.
The bills that come every month
Income tax depends on your job. Utilities depend on the house, and here the city line affects every buyer.
Inside the City of Westerville, one Utility Billing Department bills electric, water, sewer and refuse together. Westerville Electric Division is a city-owned utility. Council adopted the current residential schedule on December 2, 2025, for bills due after January 1, 2026. It has a $17 monthly customer charge and 13.706¢ per kWh for the first 800 kWh. Use above 800 kWh costs 12.364¢ in winter and 13.706¢ in summer, plus a monthly power supply cost adjustment. The city's August 2026 rate sheet showed a sample bill for 1,100 kWh of $194.14 at winter rates and $198.17 at summer rates, using that month's 2.764¢ adjustment. The adjustment changes monthly, so treat those figures as August numbers. Residential refuse is $29.75 a month in 2026. In November 2025, The Columbus Dispatch reported that the city was proposing to raise the total monthly utility bill by about 8% for 2026.
In Genoa Township, the township lists Del-Co Water Company for water and the Delaware County Regional Sewer District for sewer, billed quarterly. Electric customers can join the township's opt-out aggregation program. From June 2026 through May 31, 2027, its electric rate is fixed at no more than 9.998¢ per kWh, including capacity costs. That is a supply price only. AEP Ohio's delivery charges come on top of it, so you can't line it up against a full Westerville bill. The township also notes that a few homes inside Genoa get Westerville Electric and can't join the aggregation.
In Blendon Township, the township doesn't run any utilities. Its official list gives water to Aqua west of Hoover and Del-Co east of Hoover. Electricity comes from AEP and gas from Columbia Gas. Rumpke bills residents directly for trash, recycling and yard waste.
On AEP-served addresses, NBC4 reported on March 19, 2026, that state regulators approved an AEP Ohio rate update starting in April. It adds an average of $7.90 a month for a customer using 1,000 kWh. A separate AEP rate proposal from early 2026 drew opposing estimates from the company and from consumer advocates. As of NBC4's July 2026 update, it was still pending, so its numbers aren't a final bill impact.
In the Columbus portion, the city's Division of Power serves only addresses on its service-area map, not every home with a Columbus address. The city says its residential rates stayed below the local commercial provider's even after its January 1, 2026 increase.
So a Westerville-address home could get its power from any of three different sources. The only reliable answer comes from the meter and the current bill.
A levy that follows the parcel
Property-tax levies also follow jurisdiction. Genoa Township voters approved a Fire/EMS levy on May 6, 2025. The levy funds 98% of the township fire department. Collections started January 1, 2026, at an estimated net increase of $84 a year per $100,000 of county auditor valuation. For a home the auditor values at $400,000, that comes to about $336 a year more than before the levy. Two listings at the same price on either side of the city line can carry different tax bills for reasons like this, which have nothing to do with the house itself.
How to check a specific address before you offer
Westerville's own tax page lays out how to look up the tax district. Utilities take one more step, because the tax district doesn't always identify the provider. Genoa Township, for example, notes that a few of its homes get Westerville Electric.
- Look up the parcel on the Franklin County Auditor site for 43081 or the Delaware County Auditor site for 43082, and read the "Tax District" field.
- Confirm with Westerville's city limits lookup, or call the Income Tax Division at 614-901-6420.
- Ask the seller for recent electric, water, sewer and trash bills. The provider names on those bills show which system the home is on.
- If you work remotely, compare the home's jurisdiction against your actual work arrangement.
- If you're planning an addition or new connection on a Westerville-served lot, ask about the city's water and sewer capacity fees.
Common questions
Does a Westerville school district address mean I pay Westerville income tax?
No. The city says neither a school district nor a mailing address determines your taxing jurisdiction. Check the auditor's Tax District field.
If I live in Genoa Township and work at an office in Westerville, do I owe Westerville tax?
Yes, on wages earned there. Under the city's rules, tax is owed first where the income is earned.
Do I still file with Westerville if I'm a resident who works in a city with no municipal tax?
Yes. The city requires an annual return by April 15. Quarterly estimates may be due once your Westerville liability goes over $100.
