Clark County Property Taxes: What the Reappraisal and HB 186 Mean for Your Bill
Clark County taxes real estate on assessed value, which is 35% of the county auditor's appraised market value, so a home appraised at $200,000 is taxed on $70,000, not the full $200,000. The countywide 2026 reappraisal raised average appraised values about 32%, while House Bill 186 reshaped the state credits that reduce owner-occupied bills starting with tax year 2026. This guide covers the bill math, the real 2026 numbers, the two annual due dates, the parcel lookup tools, the appeal process, and the senior and disabled homeowner exemptions. Figures were verified against county and state sources on October 16, 2026.
How are property taxes calculated in Clark County?
Start with three terms: appraised value, assessed value, and millage. The Clark County Auditor appraises each property at 100% of fair market value, then Ohio law sets the assessed value at 35% of that figure. The gross tax is the assessed value divided by 1,000, multiplied by the total millage of every taxing district serving the address: the county, the city or township, and the school district. A mill is $1 of tax per $1,000 of assessed value.
The gross figure is not what you pay. Ohio applies state rollback credits, and for tax year 2026 those credits changed under House Bill 186, signed in December 2025: the nonbusiness credit moved from 10% to 7.5% and the owner-occupancy credit moved from 2.5% to 5.7%, for a combined reduction of about 13.2% on owner-occupied homes, per the Ohio Legislative Service Commission and Montgomery County's owner-occupancy credit page. A separate new inflation cap credit limits how much revenue school-district levies can collect, and Ohio recalculated recent bills as if the cap had applied.
Figure 1: Illustrative tax math for a Clark County home appraised at $200,000, tax year 2026. Your exact millage depends on the city, township, and school district for your address; the estimate range reflects sourced county and city effective rates, not a quote.
| Step | Example | Source |
|---|---|---|
| Appraised market value | $200,000 | Clark County Auditor |
| Assessed value (35% of appraised) | $70,000 | Ohio law |
| Total millage for the address | Varies; combines county, city or township, and school district levies | Clark County Rates of Taxation |
| State rollback credits, tax year 2026 | About 13.2% combined for owner-occupied homes (7.5% nonbusiness plus 5.7% owner-occupancy under HB 186) | Ohio LSC / Montgomery County |
| New inflation cap credit | Caps school-district levy revenue growth (20-mill floor); 2025 and 2026 bills recalculated | Ohio LSC / HB 186 |
| Typical effective homeowner rate | About 1.19% to 1.25% of appraised value countywide; about 1.69% median for the city of Springfield | Taxdrop / Ownwell |
Put the ranges together and a Clark County home appraised at $200,000 works out to roughly $2,400 to $3,400 a year in property tax, depending on which district the address falls in. That is a planning range, not a quote. In our Springfield office, we pull the actual tax history for a specific parcel before we help a buyer write an offer, because the millage can differ noticeably between nearby streets.
What did the 2026 reappraisal change for most homeowners?
Ohio requires counties to reappraise property every six years. Clark County's 2026 reappraisal raised average appraised values about 32%, according to the Springfield News-Sun, and county Auditor Hillary Hamilton has said that with the House Bill 920 reduction factor, taxes do not go up the same 32% when values rise. House Bill 920 rolls back effective rates on voted levies as values climb, so a levy collects roughly the same revenue and bills grow by a smaller, still-address-specific percentage.
One date note that confuses a lot of homeowners: Ohio collects property taxes in arrears. The installments you pay during 2026 fund the 2025 tax year, and the tax year 2026 bills with the new HB 186 credit levels arrive during 2027. If your bill jumped recently, check the appraised value on it against the county auditor's parcel record, then ask whether an appeal makes sense for your situation.
How do Clark County tax rates compare with nearby counties?
Countywide estimates suggest Clark County's effective rate runs lower than its neighbors to the west and south. The table below shows 2026 estimates; county averages hide real differences inside each county, because city, township, and school district levies stack differently at every address.
Figure 2: Estimated effective property tax rates for 2026, Clark County versus nearby Ohio counties. Countywide figures are ACS-based estimates from Taxdrop; the city of Springfield and Ohio median figures use Ownwell's directory-based methodology, so compare ranges rather than exact points.
| Area | 2026 effective rate estimate | Notes |
|---|---|---|
| Clark County (countywide average) | About 1.19% to 1.25% of appraised value | ACS-based county estimate |
| City of Springfield (within Clark) | About 1.69% median; about 1.25% to 1.88% across ZIP codes | Ownwell estimate, different methodology |
| Greene County | About 1.61% to 1.69% | ACS-based county estimate |
| Montgomery County | About 1.73% to 1.78% | ACS-based county estimate |
| Madison County | About 1.02% to 1.05% | ACS-based county estimate |
| Ohio statewide median | About 1.60% | Ownwell estimate, different methodology |
The practical takeaway is not "buy here instead of there." It is that tax comparisons only mean something at the parcel level. Two homes on the same street can sit in different school districts or taxing areas, so use the ranges to frame the conversation and then verify the exact address.
When are Clark County property tax bills due?
Ohio law (Section 323.12 of the Ohio Revised Code) splits each bill into two equal half-year installments. Clark County's cycle typically lands the first half in late February and the second in mid-July or early August, and the dates shift slightly from year to year. For the 2025 tax year bills paid in 2026, the first half was due February 27, 2026, and Treasurer Pam Littlejohn extended the second half to August 7, 2026 after delayed state legislation slowed preparation of roughly 68,000 bills.
Figure 3: The 2026 installment schedule for Clark County. Late penalties are 5% within 10 days past the due date and 10% after that, per the county's property tax page.
| Installment | Typical timing | 2025 tax year (paid 2026) | Late penalty |
|---|---|---|---|
| First half | Late February | Due February 27, 2026 | 5% within 10 days, then 10% |
| Second half | Mid-July to early August | Originally July 10, 2026; extended to August 7, 2026 | 5% within 10 days, then 10% |
How do I look up the exact taxes on a specific address?
The county auditor's property search is the source of truth. Pull the parcel record for any address to see the appraised value, assessed value, millage, and tax history, and check the school district that serves the parcel, because district millage is usually the biggest variable in the bill. The Ohio Department of Taxation's address lookup tool, The Finder, can confirm which school district an address falls in. Our community guides cover the villages around Springfield, but the tax math for a specific house always comes from that parcel record, not from the neighborhood page.
How do I appeal my property value in Clark County?
If you believe the appraised value is too high, file a complaint with the county Board of Revision using DTE Form 1, available from the auditor's forms page or in person at the A.B. Graham Building, 31 North Limestone Street, Springfield. The filing window is strictly January 1 through March 31 of the year following the tax year involved, per Ohio Revised Code 5715.19. The window for tax year 2026 values runs January 1 through March 31, 2027. No extensions are granted, and mailed complaints must arrive or be postmarked by March 31.
The Board of Revision, made up of the county auditor, the county treasurer, and the president of the board of commissioners, rules only on the value of the property, not on tax rates or the bill itself. Strong evidence is a recent appraisal or recent sales of comparable homes. If you disagree with the decision, you can appeal to the Ohio Board of Tax Appeals within 30 days using DTE Form 4. Most homeowners can handle the audit paperwork, but a real estate attorney or appraiser can help build the evidence package.
Can seniors and disabled homeowners lower their bill?
Yes, through the Ohio homestead exemption. For tax year 2026, a homeowner who is at least 65, totally and permanently disabled, or the surviving spouse of an exemption recipient (age 59 or older at the spouse's passing) may shield about $29,000 of the home's market value, roughly $10,150 of assessed value, from tax. The income cap is $41,000 of Ohio modified adjusted gross income including a spouse's income, based on the 2025 federal return. Service-connected disabled veterans at 100% can apply under a separate enhanced program.
Apply once with the Clark County Auditor using DTE Form 105A, filed from January 1 through December 31 of the year the exemption is sought, and attach the disability certificate forms if they apply. Eligibility, including whether the cap applies to you, is verified through the auditor's office and the Ohio Department of Taxation, so check the current year's rules before you file.
What do buyers need to know about taxes at closing and in escrow?
At closing, property taxes are prorated: the seller pays the share of the current tax period they owned the home, and the buyer reimburses the rest through the closing statement. Most lenders then collect an escrow, or impound, account that sets aside roughly one-twelfth of the estimated annual tax each month and pays the bill when it comes due. When a reappraisal or a new credit changes the bill, the lender adjusts the monthly charge, which is a common source of escrow changes in the first year after a purchase.
If you are shopping with a budget number in mind, ask about the current (not the listing-estimated) tax bill for the parcel, and remember that tax year 2026 bills arriving in 2027 will carry the HB 186 credit levels. Our buyer guide and first-time buyer playbook walk through the full purchase picture for Clark County.

Frequently asked questions
Will my tax bill go up 32% because of the reappraisal?
No, and county officials have said so directly. The 2026 reappraisal raised average appraised values about 32%, but Ohio's House Bill 920 reduction factor rolls back effective rates on voted levies when values climb, so the bill rises by a smaller, address-specific percentage. The HB 186 credit changes and the new inflation cap credit also move the final number.
Are property taxes higher in Springfield or in the villages around it?
It depends on the exact address. Countywide ACS-based estimates put Clark's average effective rate near 1.2% of appraised value, while Ownwell reports a median effective rate of about 1.69% for the city of Springfield with ZIP-level variation. Village parcels in places like Enon, New Carlisle, and South Vienna draw from different township and district levies, so the only reliable answer comes from the parcel record.
What happens if I miss a tax due date?
You owe the bill plus a penalty: 5% if paid within 10 days of the due date, and 10% after that, according to Clark County's property tax page. Unpaid taxes can also lead to a tax certificate sale (a lien on the property), so contact the county treasurer's office promptly if you cannot pay on time.
When can I appeal my property value?
Once a year. Complaints against the valuation go to the Board of Revision between January 1 and March 31 of the year after the tax year involved. The window for tax year 2026 runs January 1 through March 31, 2027. A recent appraisal or sales of comparable homes is the strongest evidence, and decisions can be appealed to the Ohio Board of Tax Appeals within 30 days.
How do property taxes affect my monthly mortgage payment?
Most lenders collect about one-twelfth of the estimated annual tax every month through an escrow account and pay the bill for you, so the tax is baked into your payment. When the bill changes, the escrow charge changes too. This is general education, not lending advice; your lender's loan estimate and closing disclosure show the exact escrow numbers for your purchase.
