Requirements for Using iFile

You can use iFile to file Form 502 and most other Maryland tax forms.

Before you get started using iFile, make sure you have the following information and computer system setup:

General Requirements
  • The filing due date is April 15th. If the due date falls on a Saturday or Sunday or legal holiday then the return must be filed by the next business day.
  • Complete your federal tax return before iFiling your Maryland return. Maryland law requires that your income and deductions be entered on your Maryland return exactly as they were reported on your federal return. However, all items on the Maryland return are subject to verification, audit and revision by the Comptroller's Office.
  • Obtain all copies of form W2, W2G, 1099R and 1099G that are applicable to your return.
  • If you have a balance due, your payment is due on April 15. If timely filing your return electronically, you may extend your payment date to April 30.
  • Retain copies of all federal and state tax forms, schedules, certifications and attachments for your records.
System Requirements
  • You need at least Microsoft Internet Explorer 4.0 with the display font set to default.
  • If you are using a browser other than Internet Explorer and experience difficulties try upgrading your browser to the latest version.
  • Leave your browser setting for language set to default so JavaScript and cookies are enabled.
  • You will need a printer if you wish to print your return.
  • You will need Adobe Reader 4.0 or better installed to view tax documentation in the PDF format.

Amended Returns

If you need to make an adjustment to a return that has already been submitted and processed, you must file an AMENDED return.

There are two ways to amend your return:

    1. If you submitted your original Maryland Tax Return using iFile, you may amend your previously submitted information also using iFile. Enter your Social Security Number, Last Name and Password, then select the AMEND option from the list of options.
    2. If your original Maryland income tax return was submitted in any other manner other than iFile or is for another tax year, please allow approximately six weeks for the original return to be processed. Use Form 502X to file an amended return. Forms and Instructions are available on our website or by calling (410)-260-7951. The amended return must be mailed to:

      Comptroller of Maryland
      Revenue Administration Division
      110 Carroll Street
      Annapolis, Maryland 21411-0001

If you requested an electronic funds withdrawal on your original electronic return, we recommend you file your Amended return after the date of withdrawal on your original filing.
