Is Planet Fitness HSA Eligible?

Yes, your Planet Fitness membership can be HSA eligible — but you'll need a Letter of Medical Necessity (LMN) to make it work. Gym memberships aren't automatically covered by Health Savings Accounts or Flexible Spending Accounts, but with the right documentation, you can use pre-tax dollars to pay for your Planet Fitness membership and save hundreds per year. With the new 2026 rules expanding HSA eligibility for fitness expenses, it's never been easier to make this happen.

Why Planet Fitness Isn't Automatically HSA Eligible

The IRS classifies gym memberships as "general health" expenses, which means they don't qualify for HSA or FSA reimbursement by default. The logic? Not every gym membership is medically necessary — some people sign up and never go (Planet Fitness's entire business model kind of relies on this, honestly).

But here's the thing: if a licensed healthcare provider determines that exercise is part of your treatment plan for a specific medical condition, that changes everything. Conditions like obesity, type 2 diabetes, hypertension, cardiovascular disease, depression, and anxiety can all justify a medically necessary gym membership.

How to Make Planet Fitness HSA Eligible With an LMN

A Letter of Medical Necessity is a document from a licensed healthcare provider — your doctor, nurse practitioner, or other qualified provider — that states your gym membership is medically necessary to treat or prevent a specific condition. Here's how to get one:

  • Talk to your doctor about how exercise fits into your treatment plan
  • Get an LMN that specifically mentions your Planet Fitness membership (or gym membership generally) and the condition it's treating
  • Submit the LMN to your HSA administrator along with your Planet Fitness receipts
  • Get reimbursed from your HSA or FSA

    • Planet Fitness memberships typically run $10-$25/month (or $24.99/month for the Black Card), which means you could save $120-$300 per year in pre-tax dollars. Depending on your tax bracket, that's real money back in your pocket.

    What Conditions Qualify for an HSA-Eligible Planet Fitness Membership?

    Your provider can write an LMN for a Planet Fitness membership if you have a diagnosed condition where exercise is part of the treatment protocol. Common qualifying conditions include:

    • Obesity or weight management — exercise is a first-line treatment
    • Type 2 diabetes — physical activity helps regulate blood sugar
    • Hypertension — regular exercise lowers blood pressure
    • Cardiovascular disease — cardiac rehab and ongoing fitness
    • Depression and anxiety — exercise is clinically proven to reduce symptoms
    • Chronic pain conditions — movement-based therapy
    • Osteoporosis — weight-bearing exercise strengthens bones

    You don't need a rare or severe condition. If your doctor agrees that regular exercise at Planet Fitness would meaningfully treat or manage a health issue, you qualify.

    Planet Fitness HSA Eligibility vs. Other Gyms

    Planet Fitness is one of the most affordable gym options out there, which actually makes the HSA angle even more compelling. While the tax savings on a $10/month membership might seem modest, remember — it's the same LMN process whether you're paying $10/month at Planet Fitness or $200/month at Equinox. The documentation requirement is identical.

    The real win is establishing the habit of using your HSA for fitness expenses. Once you have an LMN, you can also potentially cover related expenses like personal training sessions, fitness classes, and even home gym equipment. See our guide to HSA-eligible gym memberships in 2026 for the full breakdown.

    Can You Use FSA for Planet Fitness?

    Yes — the same LMN process works for Flexible Spending Accounts too. If anything, using your FSA for Planet Fitness is even smarter because FSA funds expire at the end of the year (or shortly after, depending on your employer's grace period). Instead of scrambling to spend down your FSA on things you don't need, put it toward a gym membership you're already paying for. Check out our FSA use-it-or-lose-it guide for more tips.

    How Hammock Helps

    Getting an LMN used to mean scheduling a doctor's appointment, explaining what you need, hoping they know how to write one, and then dealing with your HSA administrator. Hammock makes this entire process painless.

    With Hammock, you can get Letters of Medical Necessity through licensed providers without the hassle. Hammock's premium plan gives you unlimited LMNs, and when you consider the average member saves $1,000-$1,400 per year on HSA-eligible wellness expenses, it pays for itself almost immediately. Hammock also offers automatic healthcare expense tracking and a free HSA account, so you can manage everything in one place.

    The Bottom Line

    Planet Fitness memberships are HSA and FSA eligible when you have a Letter of Medical Necessity from a licensed provider. The process is straightforward — get an LMN, submit it with your receipts, and start saving pre-tax dollars on a membership you're already paying for. With 2026's expanded HSA contribution limits ($4,400 individual, $8,750 family), there's more room than ever to put your health dollars to work.
