Montgomery County, Maryland

Where to obtain records

Montgomery County Department of Finance / Division of Treasury

How to find the information

The county Real Property Tax search asks for an eight-digit bill or account number, or a street address without its suffix. It warns that a recent payment may take up to 72 hours to appear and directs unresolved posting questions to MC311. Tax Lien Sale is a separate linked guide. Request the existing ledger or dated certificate/redemption amount when the ordinary account view is insufficient.

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 Montgomery 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.
