Union County, OH tax sales

County offices

County notes

• •The county's public website moved to unioncountyohio.gov; the older co.union.oh.us address redirects there.
• •Union County Treasurer is Andrew J. Smarra, CPA. Treasurer's Office hours are 8:30 a.m. to 4:00 p.m., and the office email is [email protected].
• •The Union County Auditor publishes no forfeited-land sale page, so the Sheriff's county tax sale is the only deed-side auction the county advertises.
• •Sheriff's Office contact for sale questions: 221 West 5th Street, Marysville, OH 43040, phone 937-645-4110, email [email protected].
• •Realauction customer service handles the online mortgage foreclosure platform at 877-361-7325 or 954-734-7401. That support line does not cover the in-person county tax sale.
• •Recent posted sale dates on the Sheriff Sales page include January 14, February 11 (county tax sale), February 18, March 11, April 1, April 15, and July 15, 2026, which indicates roughly monthly or twice-monthly Wednesday sale dates rather than a single annual auction.
• •The Treasurer offers delinquent payment plans that halt the foreclosure process while payments stay current, so parcels can leave the sale list before the auction date.

Redemption

Ohio has no post-sale redemption window. On the certificate track the owner or any other person entitled to redeem may pay the county treasurer at any time before the certificate holder pays to start foreclosure, and after that up until the entry of confirmation of sale, the expiration of the 28-day alternative redemption period, or the decree that conveys title to the certificate holder. On the direct foreclosure track, delinquent land may be redeemed before proceedings begin, and afterwards up to the entry of confirmation of sale or the end of the alternative redemption period. The alternative redemption period is 28 days after an adjudication of foreclosure is journalized, and when it expires the right and equity of redemption terminate without any further order. Once title vests, a decree conveying the parcel to a certificate holder is a permanent bar to redemption.Ohio Revised Code 5721.38 - Right to redeemR.C. 5721.38Verified Aug 6, 2026

Deed deposit

For residential property the deposit is fixed by statute: $2,000 if the appraised value is $10,000 or less, $5,000 if it is above $10,000 and up to $200,000, and $10,000 if it is above $200,000. A judgment creditor buying at its own sale posts no deposit. For commercial property the deposit follows whatever requirements the sale sets. Deposit timing is set by the court or the officer conducting the sale and printed in the sale advertisement, and an online sale may take the deposit by card or other financial transaction device.Ohio Revised Code 5721.19 - Finding; appraisal and saleR.C. 5721.19Verified Aug 6, 2026

Surplus proceeds

Sale proceeds pay costs first, then the certificate holder or the taxing districts, and any residue goes to the clerk of the court within 45 days after confirmation. The clerk notifies the former owner. Residue left unclaimed 90 days after that final notice is paid into the county treasury and held for the owner, who may demand it within three years. After three years it is forfeited to the county's delinquent tax and assessment collection fund, or to the county land reutilization corporation fund where one exists.Ohio Revised Code 5721.20 - Excess foreclosure proceedsR.C. 5721.20Verified Aug 6, 2026

A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
