How to find the information

Use the Treasurer’s Property Tax Department and Pay Property Taxes navigation for collection-account inquiries. Request an existing real-property delinquency report, payment ledger or current payoff rather than relying on a valuation record.

To obtain an existing delinquent real-property report, account/payment ledger, bill copy or dated redemption/payoff calculation, provide the county tax ID/parcel or geocode if known, tax years, desired as-of date and preferred inspection or electronic-copy format. Ask which taxes, interest, penalties and costs are included and confirm any copy, certification or extract charge. A dated list, lien or deed record does not certify today’s unpaid balance.

What to ask for

“I am looking for publicly available delinquent real-property tax records for Yellowstone 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.
