Maryland Tax Connect (MTC) – Individual Taxpayers
Maryland Tax Connect for Individual Taxpayers Is Live
Maryland Tax Connect in now live!
A modern, secure way to file returns, make payments, and manage your Maryland personal income taxes online.
Maryland Tax Connect has expanded to serve individual taxpayers, building on the secure system already used by Maryland businesses. The free online portal gives taxpayers one place to file returns, make payments, view account information and filing history, check refund status, access notices, and more.
Maryland’s tax processing systems were more than 30 years old — built before online filing, smartphones, and today’s expectations for convenient, real-time access to financial information. Modernizing these aging systems represents one of the most significant technology investments in the Comptroller’s Office’s history, designed to improve security, increase transparency, and provide taxpayers with easier access to their tax information.
The transition was years in the making. Hundreds of team members contributed more than 2.6 million hours to system development, testing, training, and implementation. A planned system outage from August 21–31 allowed the Comptroller’s Office to complete the final migration of more than 4 billion tax records and prepare the system for launch.
Maryland Tax Connect for Individual Taxpayers is now live
Giving Marylanders a simpler, more secure way to manage their personal income taxes — anytime, anywhere.

Frequently Asked Questions
What is Maryland Tax Connect for Individual Filers?
Maryland Tax Connect for Individual Filers is the Comptroller of Maryland's new online tax portal. Beginning September 1, 2026, individual taxpayers will be able to file returns, make payments, check refund status, view account information, access notices, and manage their Maryland tax obligations in a single secure location.
The new portal replaces several legacy systems, including iFile and the current online bill payment system, and provides a more modern, user-friendly experience through enhanced self-service tools and real-time account information.
Why did the Office of the Comptroller launch Maryland Tax Connect?
Maryland’s core tax systems are more than 30 years old and have reached the end of their useful life.
Maryland Tax Connect replaces these aging systems with a modern tax administration platform that will enhance security, streamline filing and payments, provide better access to account information, and deliver a more seamless experience for taxpayers. This investment will ensure the Office of the Comptroller can continue serving Marylanders efficiently for decades to come.
Is this a brand-new system?
Not entirely. Maryland businesses have already been using Maryland Tax Connect for tax filing and payments. It has now expanded to serve individual taxpayers as well.
Do I have to use Maryland Tax Connect to file my taxes?
No. Maryland Tax Connect is a convenient online option, but paper filing and other existing methods remain available.
Is there a cost to use Maryland Tax Connect?
No, the portal is free to use.
Do I need to create an account to use Maryland Tax Connect?
Not necessarily. While registering for an account gives users full access to all features, some transactions, such as making an online payment, can be completed without registering. Existing filers can register directly using information from a previously filed return.
Is my information secure?
Yes. Maryland Tax Connect is built with modern security standards, implementing state-of-the- art validation, security protocols, and fraud detection models to keep your information private, replacing systems that were more than 30 years old.
Do I need to use Maryland Tax Connect if I use a tax preparer or filing software?
No. If you work with a tax preparer or file using third-party tax software, you can continue to do so; Maryland Tax Connect doesn't change that process. However, you can still use the portal alongside your preparer or software to check your account balance, view your filing history, see notices, and make payments directly, anytime you need to.
I made a payment during the transition period. Has it been processed?
Yes. Payments submitted by e-check or credit card during the transition period were accepted and processed and should be reflected in your account in the coming days. If your payment is not reflected, please allow 7 to 10 business days for the system to update. If your payment is still pending, submit a request at MyCOMConnect.
Will filing work the same way it did on iFile?
The core process is similar. You'll still file your Form 502, but Maryland Tax Connect offers a more modern interface with additional self-service features not available on iFile. User guides are available on our Tax Portal Information webpage.
My payment isn't showing in my account yet. What should I do?
Please allow 7 to 10 business days for the system to fully update. If your payment still isn't reflected after that time, assistance is available at MyCOMConnect.
Who can I contact with questions about my account information?
If you have any questions regarding your account, assistance is available at MyCOMConnect.
