Property Tax Delinquent Notice
If the property owner has received a delinquent tax bill in error first review the tax account information in the Property Tax Account Information and Bill Payment System on the County's website. If the account has a zero balance, payment has been received and recorded, no action is necessary.

If the website indicates a balance due for which the payment was made, a copy of the following documents are necessary to research the claim: if paid by homeowner or the title company's cancelled checks(s) both sides, if paid by a lender a 1099 form, if paid in person at the Department of Finance, Treasury Office the paid receipt. Documentation may be either faxed to 240.777.8947 or mail to 255 Rockville Pike, Suite L-15, Rockville, MD 20850

When the provided documentation is confirmed all accounts will be corrected and a revised statement will be mailed indicating that the corrections are complete.
