The Maryland tax refund schedule depends mostly on how you filed. If you e-filed and chose direct deposit, expect your refund about one to two weeks after the Comptroller accepts your return. Paper returns take roughly 30 days just to process, and a mailed paper check adds another week or two on top of that, so plan on four to six weeks total. During the 2025 filing season, the Comptroller’s office averaged under three days from receipt to processing for electronic returns.1Comptroller of Maryland.

Filing Season Dates and What They Mean for Your Wait
Maryland began accepting individual income tax returns on January 26, 2026, with business returns accepted starting January 13, 2026.2Comptroller of Maryland. What’s New for the 2026 Tax Filing Season The individual filing deadline is April 15, 2026. Returns submitted earlier in the season generally move faster because the Comptroller’s systems aren’t dealing with peak volume yet. Filing in late March or April often means longer waits, purely because of the backlog.
How the Timeline Actually Breaks Down
The Comptroller typically processes e-filed returns the same day they’re transmitted. Once processing finishes and your refund is approved, a direct deposit lands in your bank account within a few days.3Comptroller of Maryland. Income Tax Refund Information For most e-filers using direct deposit, the total turnaround runs one to two weeks.
Paper returns take approximately 30 days to process.3Comptroller of Maryland. Income Tax Refund Information Waiting for a mailed check adds another week or two for printing and delivery. Even if you file on paper, choosing direct deposit saves you that final stretch.
If the Comptroller takes longer than 45 days from your filing date to issue the refund, Maryland law requires the state to pay interest on the amount owed.4Comptroller of Maryland. Interest Rates for Refunds and Delinquent Taxes The rate adjusts annually. You don’t have to request the interest; it’s added automatically if your refund qualifies.
How To Check Your Refund Status
The Comptroller’s online refund tracker is the fastest way to see where your return stands. You’ll need two things: your Social Security number (or Individual Taxpayer Identification Number) and the exact dollar-and-cent refund amount from your Form 502.5Comptroller of Maryland. Maryland Income Tax Refund Status Even a one-cent difference will keep the system from pulling up your return, so verify the figure before you search.
You can also use the automated refund inquiry line at 410-260-7701 or toll-free at 1-800-218-8160. Taxpayer Services answers general questions at 1-800-638-2937, from 8:30 a.m. to 6:00 p.m.1Comptroller of Maryland. Comptroller Announces Start of 2026 Tax Season in Maryland
Give the return time to move through the system before you check. A few days is reasonable for an e-filed return; two to three weeks is more realistic for a paper filing. If you filed electronically through a preparer and nothing shows up, contact the preparer first to confirm the return was actually transmitted.3Comptroller of Maryland. Income Tax Refund Information
What Can Slow Your Refund Down
Most delays trace back to a handful of issues. Errors on the return are the most common. Math mistakes, missing signatures, and incomplete information all pull your return out of the automated queue and into manual review, which can add weeks. Tax software catches arithmetic errors automatically, which is one reason e-filers tend to see faster turnaround.
Fraud prevention reviews are another regular cause, especially for first-time filers or returns with information that doesn’t match state records. If the Comptroller needs to verify your identity, expect a letter requesting documentation with a response deadline. Not responding in time can leave your refund held indefinitely, so reply as soon as the letter arrives rather than waiting.
Returns claiming certain refundable tax credits also get extra scrutiny. The Comptroller verifies eligibility before releasing the refund, which stretches processing time even when everything on the return is legitimate. If you’re claiming the Earned Income Tax Credit or similar, build extra time into your expectations.
When Your Refund Gets Redirected
Maryland runs a Tax Refund Intercept Program (TRIP) through the Central Collection Unit. If you owe money to the state or one of its agencies, the Central Collection Unit certifies your name to the Comptroller’s Revenue Administration Division, and your refund is redirected to cover the debt.6Maryland Department of Budget and Management. State Tax Refund Intercept Program (TRIP) The intercepted amount may include accrued interest and collection costs.
Common triggers include past-due child support, unpaid state taxes, and other debts owed to Maryland agencies. You’ll get a notice explaining which agency claimed the money and how much was taken. If you think the debt is wrong, you have 15 days from the notice date to request a written investigation from the Central Collection Unit.6Maryland Department of Budget and Management.

One thing to know before filing jointly: a joint refund can be intercepted for one spouse’s individual debt.
Situations That Change the Schedule
Wrong Bank Information
If you enter incorrect routing or account numbers, the state will not track down the misdirected funds. Instead, the Comptroller issues a paper check, which adds several days to your wait.3Comptroller of Maryland. Income Tax Refund Information Double-check the numbers before submitting.
Foreign Bank Accounts
Direct deposit isn’t available for accounts outside the United States. The Comptroller automatically mails a paper check in that case, so expect delivery times to reflect the mailing method.3Comptroller of Maryland. Income Tax Refund Information
Amended Returns
Amended returns follow a slower track. Wait at least six weeks after filing your original return before submitting Form 502X, so the two filings don’t collide in the system.7Comptroller of Maryland. Maryland Form 502X Amended Tax Return Amended returns require manual review and take longer than originals to process. And a detail that catches people off guard: refunds from amended returns are always issued as paper checks, even if you chose direct deposit on the original.3Comptroller of Maryland.

How Long You Have To Claim a Refund
You generally have three years from the date you paid the tax to file a refund claim in Maryland.8Maryland General Assembly. Maryland Code Tax – General 13-1104 Miss that window and the money is gone regardless of how much you overpaid.
For amended returns, the deadline is three years from the original filing date or two years from the date you paid the tax, whichever is later. A few exceptions extend the deadline, including claims resulting from federal audit adjustments, where you get one year from the IRS’s final determination to file with Maryland.7Comptroller of Maryland. Maryland Form 502X Amended Tax Return If a refund check was issued but never cashed, the funds eventually transfer to the state’s unclaimed property program after a dormancy period, and you can search for and claim them through the Comptroller’s website.
