Most buyers comparing Dublin and Westerville assume Dublin is the pricier tax jurisdiction. The data says the opposite.
On a $700,000 home, the same property in Westerville costs roughly $4,000 more per year in property tax than the same property in Dublin. That gap covers a year of in-state tuition. Every year. Compounding over a seven-year hold.
This is not a footnote. It is the difference between a $4,200 monthly payment and a $4,535 monthly payment on the same loan amount, same rate, same down payment. The only variable is which parcel the house sits on. Most buyers find out at the closing table, or three months later when escrow rebalances. That should embarrass the industry. It does not embarrass the industry. My job is to make sure you know before you write the offer.
Here is what every Dublin homebuyer in 2026 should know, with numbers you can look up yourself.
The Effective Rate Comparison
Dublin's median effective property tax rate sits at roughly 1.94 percent. Westerville's effective rate runs closer to 2.55 percent. Both are above the Franklin County average of 1.47 percent, but the gap between them is substantial. (Rates sourced from Franklin County Auditor published millage schedules; verify the current year's figures at the Franklin County Tax Estimator before using in any offer analysis.)
On a $700,000 home, the math runs like this:
- Dublin at 1.94 percent: approximately $13,580 per year
- Westerville at 2.55 percent: approximately $17,850 per year
- Annual delta: approximately $4,270
Over a seven-year hold, the same physical house in Westerville costs you nearly $30,000 more in property tax than the same house in Dublin. Same general region, same Franklin County, comparable metro commute. The difference is millage policy.
Every district rate is published. The Franklin County Auditor maintains rates by district, and the Franklin County Tax Estimator tool will return the exact annual tax for any parcel number in about 90 seconds. Most lenders quote a county-average estimate that runs $200 to $400 per month off the real number. That is the root cause of nearly every escrow shock I have watched in five years of closings.
Why the Gap Exists
The biggest driver is school district millage. Dublin City Schools and Westerville City Schools both operate well-resourced systems, but Westerville's millage stack has historically run higher. Part of that is a longer history of operating levies. Part of it is how the most recent voter-approved increases compounded onto the base rate.
The second driver is municipal services. Both cities operate at the city level rather than relying solely on township service, and Westerville's services layer adds a few more mills.
The third driver is special assessment districts. Both Dublin and Westerville contain sub-districts with community development authority levies, particularly in newer construction corridors. Those special assessments can swing your effective rate by up to half a percent, and they do not always show up in the standard property tax line on a listing sheet.
The Within-Dublin Variation
The question "what is Dublin's property tax rate" is the wrong question. Dublin is not one tax rate. It is several, and the spread is large enough to matter on any purchase.
Zip code 43017, which sits mostly inside Dublin City Schools, runs at the higher end of the Dublin range. On a $515,000 home, the median annual tax runs roughly $9,500, with an effective rate near 1.85 percent.
Zip code 43016 is partly served by Hilliard City Schools and partly by Dublin City Schools. The parts of 43016 under Hilliard's millage run lower. On a similarly valued home, the annual tax comes in around $6,650, with an effective rate near 1.29 percent. That is roughly $2,850 per year difference within the same loose geography most people call "Dublin."
The Jerome Village build-out, north of Hyland Croy Road, sits in Plain Township and is served by Jerome Schools under the Dublin City Schools system. But it carries newer community development district overlays. Annual tax on a similarly priced home runs higher because of that special assessment layer.
If a buyer tells me they want to be in Dublin and they have not pulled a parcel-level estimate on the specific street they are targeting, I slow them down. The street-level swing within Dublin is larger than the rate spread between Dublin and most other Central Ohio suburbs.
How to Pull the Real Number in 90 Seconds
This is the step most agents skip and most lenders quote wrong.
Step 1. Get the parcel number. It is in the property details on any active listing, in the MLS detail view, and in the Franklin County Auditor property search by address.
Step 2. Open the Franklin County Tax Estimator tool and paste the parcel number.
Step 3. The tool returns the current annual tax exactly as billed. No estimation. The bill the seller paid last year is the baseline for what you will pay, with one adjustment to account for.
Step 4. Adjust for the 2026 triennial reappraisal. The Franklin County Auditor is mailing value-change notices through June 2026. If the assessed value on a specific parcel is changing, the new tax bill (effective January 2027 collections) will reflect the new value times the current effective rate. The estimator does not auto-update for this until 2027 bills issue, so a high-appreciation property may run slightly higher than the tool currently shows.
Step 5. Convert to monthly PITI. Divide the annual tax by 12. Add that to your principal and interest, add monthly insurance, and compare the total to what your lender used in pre-approval. If the lender's number is $200 to $400 per month different from the parcel estimate, you need to flag that before the financing contingency clock starts, not after.
Last spring I had a client who almost lost a Dublin home because the lender's pre-approval used a county-average tax estimate that ran $312 per month under the actual parcel tax. The seller's counter-offer pushed the total monthly payment over what the buyer actually wanted to carry. We caught it the night before signing. We restructured the offer, renegotiated, closed. They are happy. If we had missed it by 24 hours, they would have closed and been miserable at the number every single month.
What This Means If You Are Selling in Dublin
If you are selling a Dublin home in 2026, you are competing against Westerville and New Albany inventory. The tax math is a real competitive advantage. A buyer running side-by-side numbers on comparable homes will see that your Dublin house costs them $300 to $400 less per month than the equivalent Westerville house at the same listed price. That is actual buying power the buyer can redirect toward a higher offer, better reserves, or a faster close.
Use that in the offer-comparison conversation. It is not spin. It is arithmetic.
What This Means If You Are Selling in Westerville
Do not pretend the tax gap does not exist. A buyer who has done their homework will see it and will bring it up. The answer is not "our taxes are competitive." The answer is what Westerville offers that Dublin does not, on its own terms: Uptown Westerville's walkable downtown, the Otterbein University presence, the established neighborhoods with mature trees and known block character, the density of resale inventory relative to new construction. Those are real arguments. They are better arguments than avoiding the number. Outvalue the gap on substance.
The Quick Check Before Any Offer
Three steps, 15 minutes, prevents the most common avoidable mistake at the closing table.
- Pull the parcel-level tax bill from the Franklin County Auditor estimator. Verify the number matches what your lender used in pre-approval.
- If the lender's figure is more than $100 per month off the parcel estimate, escalate to your loan officer immediately. They will rerun underwriting with the correct number. Losing 24 hours now is far better than discovering the gap at appraisal review or, worse, after keys change hands.
- If the property is in a special assessment district, ask the listing agent for the most recent annual special assessment statement. Some community development districts add $1,500 to $3,000 per year that does not appear in the standard property tax line at all.
