Military Outreach for Service is a Tier-2 IRS Employee Resource Organization (upgraded from a Tier-1 Employee Organization). 

As differentiated by a Tier-1 Employee Organization (EO), a Tier-2 ERG is viewed as a business asset to the IRS, and has partnered with IRS Diversity & Inclusion to align with IRS business strategy.


The National Office of MOS consists of:

  • 5 elected, and voting board members
  • 3 appointed, and non-voting board members
  • 3 non-voting executive sponsors

Additionally, Chapter Presidents are highly-encouraged to participate in decisions made in the national office, to ensure the organization is always focused on the needs of the membership.
