ANNAPOLIS, Md. (July 6, 2026) — The Office of the Comptroller of Maryland is reminding taxpayers that Maryland’s legacy tax systems will be taken offline in phases beginning later this month as the Comptroller’s Office completes its transition to Maryland Tax Connect for Individual Taxpayers, a new online tax portal launching September 1, 2026.
Taxpayers who need to file a return, make a payment, or access account services through the Comptroller’s current online systems should do so before the applicable deadlines below. Services will begin going offline as early as July 24.
Key dates taxpayers should know:
July 24 — Last day for in-person paper check payments at branch offices for personal income, pass-through entity, and fiduciary taxes, by 4:30 p.m. The Comptroller’s Office will resume accepting paper checks at branch offices on September 1.
July 29 — Last day to electronically file a return or make a payment through current online systems, by 11:59 p.m. Online filing and payments for individuals will resume in Maryland Tax Connect on September 1.
August 20 — Last day to electronically file and pay business taxes, by 11:59 p.m.
August 21–31 — All systems down for final migration. E-check and credit card payments will continue to be accepted and processed during this period, though they will not post to taxpayer accounts until after September 1.
September 1 — Maryland Tax Connect for Individual Taxpayers is live. All services resume in the new portal.
No penalties will be assessed for any payment or filing deadline that falls within the outage window.
E-check payments will remain available during the entire transition period. This free, fast, and secure payment method debits directly from a taxpayer’s bank account and can be used for existing balances, estimated payments, and extension payments. Payments submitted during the outage window will be accepted and processed, though they will not post to taxpayer accounts until after September 1. More information is available at [MarylandComptroller.gov/Payments]MarylandComptroller.gov/Payments.
Maryland Tax Connect for Individual Taxpayers replaces the Comptroller’s legacy tax systems, including iFile and the current online bill payment system, with a modern platform that offers real-time account balances, a complete filing history, easier payment options, and expanded self-service tools, all in one place. The new portal is free to use and will be available to all Maryland individual taxpayers beginning September 1, 2026.
