Can Domestic Partners Fund One HSA to the Married Couple Limits?

If you and your domestic partner are contemplating contributing to a Health Savings Account (HSA), you might wonder if you can both fund one HSA up to the limits set for married couples. The short answer is that the IRS does not allow domestic partners to combine their contributions into one HSA to reach the higher family contribution limit; each individual's contribution is separate.

For tax purposes, domestic partners are not considered spouses under federal law. However, each partner can have their own separate HSA as an individual, subject to the individual contribution limits set by the IRS.

Here are some key points to keep in mind:

  • Domestic partners cannot combine their contributions into one HSA to reach the higher family contribution limit.
  • Each partner is subject to their individual contribution limit based on their age and type of coverage (individual or family).
  • The total contributions made by both partners should not exceed the family limit set by the IRS.
  • Employer contributions count toward the annual contribution limits for each partner.

It's essential to understand the rules and limitations regarding HSAs, especially when it comes to contributing as domestic partners. While you cannot pool your contributions together to reach the family limit, both partners can still benefit from individual HSA contributions and enjoy tax advantages.


When considering whether you and your domestic partner can fund a shared Health Savings Account (HSA) up to the married couple contribution limits, it's important to know that the IRS treats domestic partners differently from spouses. Unfortunately, this means you cannot pool your contributions to reach those higher limits, but don't worry—there are still viable strategies for maximizing your HSA benefits.
