Archer MSA vs HSA: Understanding the Key Differences

When it comes to saving for healthcare expenses, two popular options are Archer MSAs (Medical Savings Accounts) and HSAs (Health Savings Accounts). While they share some similarities, there are key differences between the two that individuals should be aware of.

Archer MSA is a predecessor to HSA, created in 1997 as part of the Medicare Prescription Drug, Improvement, and Modernization Act. On the other hand, HSAs were established in 2003 under the Medicare Modernization Act.

Here are the main differences between Archer MSAs and HSAs:

  • Eligibility: Archer MSAs are available to self-employed individuals or employees of small businesses with up to 50 employees who have a high deductible health plan. HSAs are available to individuals who have a high deductible health plan, regardless of employment status.
  • Contributions: Archer MSAs have annual contribution limits set by the government, while HSAs have higher annual contribution limits that are adjusted for inflation each year.
  • Contribution Sources: With Archer MSAs, both the employer and the employee can contribute to the account. In contrast, HSAs allow contributions from the individual, employer, or any other third party.
  • Portability: HSAs are portable, meaning the funds can be carried over from year to year and can be transferred between employers. Archer MSAs are not as portable and have more restrictions on fund transfers.

Ultimately, the choice between an Archer MSA and an HSA will depend on your specific healthcare and financial needs. Understanding the differences between the two accounts can help you make an informed decision.


When deciding between Archer MSAs (Medical Savings Accounts) and HSAs (Health Savings Accounts), it's crucial to understand their differences in terms of eligibility, contributions, and portability, as each option has its unique benefits and restrictions.
