Logon To the Individual Taxpayer
Online Service Center
Are you making the most of our online services?
Certain services, such as viewing your 1099G or a history of your estimated
payments, require an enhanced registration. If you do not have an enhanced
registration you may upgrade your registration by clicking on the User Profile
link once you have successfully logged on. For immediate access to our enhanced
applications you will be asked to provide the federal adjusted gross income from
your previous year's Maryland income tax return. If you do not have your federal
adjusted gross income you may enhance your registration by signing the document
provided and mailing it to the Comptroller's office as instructed.
