Email Security Warning!
When sending an email to the Comptroller of Maryland, do not include information such as your full social security number (use only the last 4 digits), bank account numbers, routing numbers, or any other sensitive information.
If you wish to send sensitive information, email a description of the issue (without the sensitive data), and let us know you have confidential information to send. We will reply back via an encrypted email account, which will have "#secure#" in the email subject. In reply to the secured email, you may then provide the additional detail, including the sensitive information.
