Who is eligible to use online filing?

Anyone that must file a Form M-1 can file it online.

What do I need to get started as a new user?

You will need a unique Personal Identification Number (PIN) which can be used once only (see next question).  Once you've received your PIN (with accompanying access instructions), you can access the system and set yourself up as a user by selecting the New User function. This is required for first-time users to establish themselves on the system and to set up their profile, which includes confirming general user information, and choosing the desired account ID and password.

How do I get a user PIN?

New filers can request a user PIN (to be sent by postal mail) by using the PIN request form at

If I lose the user PIN, can I request a replacement online?

Yes, if the PIN is lost, a replacement can be requested at but will be fulfilled by postal mail. The program will not issue a PIN online.

If I previously filed online, do I need to use a PIN?

A PIN is only used once to initially set-up the account.  After the account is created, the PIN can no longer be used.  The user will instead use the username and password he or she chose when setting up the account to log in.

Is the information I submit secure and private?

Yes, all Form M-1 information submitted and transmitted online will be fully encrypted and secure.

How many users can access the same account or filing at the same time?

  • Each PIN can only be used by one administrator to set up one account.
  • One account can be used to submit filings for multiple plans.
  • Each account can only be associated with one account ID and password.
  • Any user who wishes to access the account must know the account ID and password.
  • More than one user can access the same account and its filings at the same time, but everyone must know the account ID and password for that account.
  • Care should be taken so that only one person at a time edits a specific filing. If multiple users edit one filing simultaneously, the last saved changes will overwrite previous ones.
