What Is Military OneSource and Who Can Use It?

Updated

Military OneSource (militaryonesource.mil) is the U.S. Department of Defense's resource website for active duty service members and their families. It offers 24/7/365 personal support by phone or secure live chat, plus digital tools and guides on taxes, moving (PCS), benefits, counseling, and more. It is built for military life, not the general public — eligibility applies, and the site provides a way to check it.

Who it serves

The site describes its audience as service members, spouses, their family, and survivors. Its topic areas also address extended family and friends, wounded, ill or injured service members and their caregivers, and youth and teens. If you are unsure whether you qualify, the site's "Learn about eligibility" link is the place to confirm before relying on a service.

What you can get

Support comes in two forms: direct help from people, and self-service tools.

Talk to someone

  • Phone: 800-342-9647, available 24/7/365, with OCONUS and TTY/TDD options listed.
  • Secure live chat: log in to start a session for quick answers or working through a problem.
  • Coaching and consultations: help with topics such as managing money and relationships.
  • Counseling: for individuals, couples, and families.

Use tools and resources on your own

  • Benefits Finder — travel, education, taxes, PCS, and more.
  • Resources Finder — child care, spouse scholarships, Military and Family Life Counselor (MFLC) support.
  • MilTax — free tax services.
  • Plan My Deployment checklists and a relationship resource tool.
  • EFMP & Me and a Military Funeral Honors Directory.
  • DPS (Defense Personal Property System) for household goods moves, plus "Preparing to Move" guidance under the moving/PCS section.

How the site is organized

Content is grouped by life topic, so you can go straight to what you need:

Topic area Examples of what's covered
Military Basics New to the military, training and logistics, info for extended family
Deployment Preparing, during deployment, returning home
Education & Employment For spouses, service members, youth and teens
Financial & Legal Personal finance, taxes, legal
Health & Wellness Mental health, nutrition and fitness, prevention and care
Emergencies & Disasters Personnel accountability, disaster preparedness, evacuation
Casualty & Mortuary Affairs Bereavement and grief, survivor assistance

There is also a section for service providers and leaders with a knowledge center, data and research, and orderable or downloadable products.

Practical notes before you start

  • Create an account or log in to use secure chat and personalized tools; some resources may require it.
  • Call if you need an answer now — the phone line is the fastest route outside business hours.
  • Check eligibility first if you are a family member, survivor, or extended family, since services are tied to military status.
  • Start with a Finder tool (Benefits or Resources) if you don't yet know which program fits your situation; it narrows the options before you read detailed guides.

In short: Military OneSource is a one-stop support hub for the military community — use the phone or chat for personal help, and the finders and topic guides to handle taxes, moves, benefits, and family needs on your own schedule.
