Where to obtain records

Summit County Treasurer / Property Tax Records

How to find the information

Delinquent Property Taxes publishes separate real-property, personal-property, mobile-home, active-tax-lien and advertised lists. At review those groups were labeled as of October 26, 2026. Select the correct record category and snapshot, then ask Treasury for an existing current ledger or redemption quote.

For an existing delinquent real-property report, parcel account/payment ledger, Statement of Taxes Due or dated tax-lien redemption amount, provide the account/parcel/schedule reference, tax years and desired as-of date. Ask whether current delinquency, sold or county-held liens, later endorsements, interest and advertising/redemption costs are included and whether recent payments have posted. Confirm inspection, electronic-copy, certification, research and extract fees. Assessor valuations, loan foreclosures and dated sale lists do not certify today’s unpaid balance.

What to ask for

“I am looking for publicly available delinquent real-property tax records for Summit County for [tax year]. Which office maintains these records? Is there an online search or downloadable list? If not, how can I request a copy, and what fees apply?”

Have the property address, parcel number, owner name, and tax year ready when searching for a particular property.

County-specific notes

Only the publication page and labels were reviewed; linked taxpayer spreadsheets were not downloaded. The separate active-lien and advertised lists do not cover the same account population as all unpaid real-property taxes. No taxpayer query, account registration, CAPTCHA completion, public-records request, bidder registration, upload or payment was submitted. No taxpayer rows or owner-list attachments are included.
