Key facts

  • Maryland splits paper Form 502 returns by address: return with payment vs. return without payment — mailing to the wrong one can delay processing.
  • Make checks or money orders payable to the "Comptroller of Maryland".
  • Place Form PV with the attached check or money order on top of Form 502 — don’t staple it to the return.
  • A mailed return is generally considered filed on time if it is postmarked by the state filing deadline — sign and date it, since an unsigned return isn't considered filed.
