Comptroller of Maryland News

The Office of the Comptroller of Maryland announced on June 15 that Maryland Tax Connect, the agency’s secure, self-service tax portal, will expand to serve individual taxpayers beginning September 1, 2026, marking the first system-wide modernization of Maryland’s tax infrastructure in more than 30 years.

Maryland Tax Connect is an online tax portal offering real-time account balances, complete filing history, and expanded self-service tools, already in use by Maryland businesses to file returns, manage accounts, and communicate directly with the Comptroller’s office. Beginning September 1, the portal will extend those same capabilities to individual filers, including the ability to file income tax returns, make estimated payments, set up payment plans, and more. The new portal will be free to use and available to all Maryland individual taxpayers beginning September 1.

This is one of the most significant technology investments Maryland has made in a generation, and change can be accompanied by challenges. That’s why the transition is scheduled for the end of August, when tax activity across the state is at its lowest, to minimize disruption for Marylanders. Because all of the data currently housed in our state’s mainframe system must be transitioned to the new cloud-based system, most services will be temporarily unavailable beginning in late July. If you have a payment due or a return to file in August, please review the schedule below and act before the applicable deadline.

Key Dates

July 24 Last day for in-person paper check payments at branch offices for personal income, pass-through entity, and fiduciary taxes. Branch offices close at 4:30 p.m. Electronic payments and money orders will continue to be accepted. The Comptroller’s Office will resume accepting paper checks for these tax types on September 1.

July 29 July 29 is the last day, by 11:59 p.m., for individuals to electronically file a return or make a payment on our website. Online filing and payments for individuals will resume on Maryland Tax Connect on September 1.
August 20 August 20 is the last day, by 11:59 p.m., to electronically file and pay business taxes via the Maryland Tax Connect portal. Normal operations resume on September 1 in Maryland Tax Connect.
Aug 21–31 All systems are unavailable for the final migration. During this period, payments by e-check and credit card will be accepted and debited from bank accounts, but will not be posted to the taxpayer account until after September 1. Learn more at MarylandComptroller.gov/Payments.
September 1 Maryland Tax Connect for Individual Taxpayers is live! All services resume in the new portal.

 

What’s new in Maryland Tax Connect for Individual Taxpayers:

The new portal will be free to use and will provide real-time account balances, complete filing history, direct debit and e-check payment options, and access to your notice history, all without contacting our office.

In the weeks to come, our office will continue to share news of this important transition and what it means for Marylanders. You may see information on social media, at events, or in the news. Additionally, we are expanding our FAQs related to this new tax portal and what to know during our transition.

Sincerely,

The Maryland Office of the Comptroller
