Do you need to file for an Extension Request?

Welcome to the Comptroller of Maryland's Internet Extension Request Filing system. This system allows instant online electronic filing of the 500E/510E forms. An automatic extension will be granted if filed by the due date. A 7 month extension can be granted for Corporations using Form 500E and S Corporations using Form 510E. A 6 month extension can be granted for Partnerships, Limited Liability Companies and Business Trusts using Form 510E.

In order to use the online system you must meet the following eligibility requirements:

  • Have previously filed a Maryland Form 500 or 510
  • Have an estimated balance due on Line 5 of ZERO (0) on the Form 500E/510E

If you do not meet the eligibility requirements you can apply for an extension of time to file using the 500E/510E forms and following the instructions on the appropriate form.
