Maryland Tax Extension 2026
Maryland automatically honors federal Form 4868 extensions if no tax is owed. If you owe state or county tax, submit Form 502E online by April 15, 2026.
What is a Maryland Tax Extension?
Maryland state returns (Form 502) are due April 15, 2026. If you filed federal Form 4868 and owe no Maryland state or local tax, your 6-month extension to October 15, 2026, is automatic. If you owe tax, you must file Form 502E or Form PV online by April 15.
Extension to File ≠ Extension to Pay
An extension gives you more time to file your Maryland Form 502, not to pay. Taxes owed must be paid by April 15, 2026, to prevent a 10% penalty and 1% monthly interest.
You Should File an Extension If…
Waiting on 1099s
Maryland freelancers and gig workers often receive forms late. An extension ensures your return is 100% accurate before filing.
Relocation to Maryland
If you recently moved to Maryland, you will need extra time to apportion income and reconcile part-year resident returns across state lines.
Self-Employed in Maryland
Maryland creators and small business owners can extend the deadline to fund and claim allowable contributions to SEP-IRAs and Solo 401(k)s.
Living or Earning Abroad
Maryland-based digital nomads and remote workers traveling overseas need the extended time to verify foreign income and tax credits.
Complex Deductions
Avoid rushing write-offs for gear, home office, and mileage. Take the full 6 months to ensure every allowable tax deduction is calculated.
Avoiding Late Penalties
The IRS late-filing penalty is 10x higher than the late-payment penalty. Filing Form 4868 instantly eliminates all failure-to-file penalties.
Maryland creator tip: The Comptroller of Maryland imposes a flat 10% penalty on late balances. Filing an extension and paying your estimate by April 15 completely prevents this penalty.
