Maryland where's my refund: using Maryland Tax Connect

What changed: Maryland Tax Connect

Maryland's refund status check used to sit on a standalone page at interactive.marylandtaxes.gov. That page now sends visitors to Maryland Tax Connect (mdtaxconnect.gov), and the Comptroller's tax services page lists “Where's My Refund” under Payments & Refunds. Older guides that describe the standalone page, its menu or its phone prompts are describing a system that has been replaced.

The Where's My Refund form we retrieved on Tax Connect needed no login. It asks for three things: your Social Security number or Individual Taxpayer Identification Number, the tax year the refund is for (2025 or 2024 were offered), and the expected refund amount. Its results area carries two default messages, “Transaction incomplete” and “Transaction Not Found.” The Comptroller does not explain either on the pages we could read, so treat any definition, including ours, as a reading. The most likely cause of a not-found result is a mismatch in one of the three inputs, so re-check the tax year and the refund amount against your return, not against a preparer's estimate.

The one timing rule Maryland publishes

The 2025 resident booklet gives no processing range for an original return. What it says is in its amended-return guidance: do not file an amended return until enough time has passed for the original to be processed, and for a current-year return, allow at least six weeks. That is a minimum-wait marker for a different purpose, but it is the only published number, and it is a fair signal for the earliest point at which silence is unusual. The booklet also reports that during the 2025 filing season the Comptroller's Office processed over 3 million returns and issued over 1.8 million refunds valued at more than $2.4 billion, which gives a sense of volume but not of timing.

Because Maryland gives no ceiling, the calculator shows only the six-week marker and treats everything else as unknown. A page that quotes you a firm Maryland timeline is repeating something not found on the Comptroller's own pages we could read.

Phone lines and what the booklet says about payment

The booklet lists the refund information line as 410-260-7701 from Central Maryland and 1-800-218-8160 from elsewhere. It says unless you request otherwise the Comptroller mails a paper check, and that direct deposit goes to the account you enter on the return. It adds that Maryland is not responsible for a lost refund if you enter the wrong account information, and that if the financial institution tells the Comptroller a deposit failed, a refund check is mailed. Form 588 lets a refund be split across more than one account.

Worked example (hypothetical dates)

You e-file on February 10, 2026. The Comptroller's six-week marker falls on March 24, 2026. If Maryland Tax Connect returns “Transaction Not Found” on February 12, there is nothing alarming in it: re-check the inputs first and wait. If you are still unable to find the return on March 24, call 1-800-218-8160, or 410-260-7701 from Central Maryland, with the return in front of you. If you mailed a paper return on the same day, the same marker applies but the tool may not show the return for longer.

Common mistakes

• Following a guide that still points to the old interactive.marylandtaxes.gov page.
• Entering the refund amount from the preparer's estimate or a prior draft.
• Selecting the wrong tax year in the dropdown.
• Filing an amended return before six weeks have passed.
• Reading “Transaction Not Found” as proof the return was lost.

Who this is for and what it leaves out

Maryland residents and part-year filers with a Form 502 refund still outstanding, particularly those who used the old status page last year. It does not read Maryland Tax Connect, store details, or predict timing. The Comptroller's help articles for this topic render only with JavaScript, so we could not read them; the figures here come from the booklet and the Tax Connect form itself. The federal refund is tracked separately with the IRS.
