Do I Lose My Employer HSA Contribution If I Change Plans Mid-Year?

If you are considering changing plans mid-year and you have an HSA (Health Savings Account) with contributions from your employer, you may be wondering what happens to the employer HSA contribution. It's important to understand the implications of changing plans on your HSA funds.

When you change health insurance plans mid-year, your HSA balance stays with you - it's your personal account. However, how you are able to use the funds may vary depending on the new plan you select.

Employer contributions to your HSA typically follow the 'last-month rule', which means that if you have an HSA-eligible HDHP (High Deductible Health Plan) on December 1 of a given year, you are considered eligible for the entire year. Therefore, if your employer makes contributions to your HSA throughout the year, the full amount is yours to keep even if you change plans mid-year.

It is essential to check the new plan's HSA eligibility and any contribution policies to ensure that you can continue to use the HSA funds seamlessly. Here are some key points to consider when changing plans:

  • Verify if the new plan is HSA-eligible.
  • Understand any contribution matching or requirements from the new plan.
  • Check if there are any restrictions on using HSA funds in the new plan.

Changing health insurance plans can be a complex process, especially when you have an HSA. It's always advisable to consult with your HR department or a financial advisor to understand the implications and make informed decisions.


If you're contemplating a mid-year change to your health plan and currently have an HSA with employer contributions, it can raise some important questions about your funds. Understanding how your employer's contributions will affect your HSA is crucial to managing your healthcare finances.

The good news is that your HSA balance – the funds in it – is tied to you personally and not your employer or health plan. This means that regardless of any changes to your healthcare coverage, the money in your HSA remains yours.

Under the 'last-month rule', if you have an HSA-eligible HDHP on December 1, you qualify for the full annual contribution limit, making it important to stay informed about your contribution eligibility as you navigate new plans.

When transitioning to a new health plan, ensure that you are aware of HSA eligibility criteria and the rules that may apply.

  • Confirm that your new plan qualifies for HSA.
  • Review any contribution guidelines or employer match policies enforced by your new plan.
  • Look out for limitations regarding the usage of HSA funds with the new coverage.

Considering a change can be a bit daunting, so it's recommended you connect with HR or a financial consultant to make well-informed steps.
