St. Mary's County, Maryland

Where to obtain records

St. Mary's County Office of the County Treasurer

How to find the information

The county Tax Bill Lookup offers direct account-number lookup or name/address search and links a separate Municipay payment service. It warns that ownership information is refreshed annually and recommends address or parcel number for new owners. MetCom water/sewer accounts may be included in the county sale. Use extension 3300 for the existing ledger or dated sale/certificate and redemption record.

For existing records, provide the account/parcel identifier, tax or fiscal year and desired as-of date. Specify an ordinary unpaid collection ledger, dated tax-sale advertisement, certificate history or a current redemption quote. Ask whether municipal bills, utilities, special assessments, penalties, interest, later taxes and certificate-holder costs are included. Confirm inspection, electronic-copy, certification, research and extract charges before ordering. SDAT ownership/assessment data, a payment receipt and an old sale list do not certify the complete current amount due.

What to ask for

“I am looking for publicly available delinquent real-property tax records for St. Mary's 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.
