Maryland to Roll Out Final Stages of Maryland Tax Connect

Maryland is undertaking its most significant tax system modernization effort in more than 30 years. Beginning September 1, 2026, Maryland Tax Connect will be available to individuals, pass-through entities, trusts, and estates. This expansion builds on the platform already used by payroll withholding and sales and use tax filers, extending its benefits to all Maryland taxpayers.

What is Maryland Tax Connect?

Maryland Tax Connect is a secure self-service portal that allows taxpayers to interact directly with the Comptroller’s Office. Through the portal, taxpayers can file returns, make payments, view filing history and account balances, access notices, track refunds, and communicate with the Comptroller’s Office all online, 24/7, and at no cost.

The Comptroller’s Office describes the new system as faster, simpler, and more secure than the legacy platforms it replaces. Taxpayers will have access to real-time account information and enhanced security features, creating a more transparent and efficient experience.

A project of this scale comes with challenges, as decades of tax data must be migrated from legacy systems to a cloud-based platform. To help taxpayers prepare, the Comptroller’s Office has published a timeline highlighting key dates during the transition period.

The Comptroller’s Office has also created an Individual Tax Hub with updates, resources, and answers to frequently asked questions. We encourage taxpayers to review these materials and keep the following points in mind:

• Reviewing the migration timeline and planning ahead for any filing, payment, or account maintenance needs during the transition period are recommended.
• Existing usernames and passwords will not transfer to Maryland Tax Connect. Taxpayers will need to create a new account when the system launches.
• Copies of recent tax returns, notices, and payment confirmations should be readily available in case account information is temporarily inaccessible.
• E-check payments will remain available throughout the transition and can be made without a service fee when paying directly from a bank account.
• From August 20–31, Comptroller agents will have limited access to taxpayer accounts. While account-specific assistance may be restricted, agents will continue to answer general questions and provide guidance.
• After September 1, taxpayers can take advantage of the portal’s self-service features to manage their accounts, make payments, access notices, and communicate securely with the Comptroller’s Office.

Maryland Tax Connect represents a major step forward in how taxpayers interact with the state. As always, we are here to help you navigate the transition and make the most of the new system’s capabilities.
