HSA/FSA for Sauna Purchases: How to Use Pre-Tax Health Dollars
Yes, you can potentially use your Health Savings Account (HSA) or Flexible Spending Account (FSA) to buy a sauna. It's not automatic - you need a Letter of Medical Necessity (LMN) from a licensed healthcare provider - but the process is straightforward and can save you 25-40% on your purchase depending on your tax bracket.
How HSA and FSA Work
Quick refresher in case you need it:
- HSA (Health Savings Account): Available with high-deductible health plans. Contributions are tax-deductible, growth is tax-free, and qualifying medical expenses are tax-free. Triple tax advantage. Funds roll over year to year.
- FSA (Flexible Spending Account): Available through employer plans. Contributions are pre-tax. Use-it-or-lose-it each year (with some exceptions). Qualifying medical expenses are tax-free.
The key question is whether a sauna counts as a "qualifying medical expense." The answer: it can, with proper documentation.
The Letter of Medical Necessity
The IRS allows HSA/FSA funds to be used for items that are prescribed by a healthcare provider to treat or prevent a specific medical condition. A Letter of Medical Necessity (LMN) from your doctor states that a sauna is medically necessary for your specific health situation.
Common qualifying conditions include:
- Cardiovascular disease or hypertension
- Chronic pain conditions (fibromyalgia, arthritis)
- Depression or anxiety disorders
- Chronic inflammation
- Certain skin conditions
- Respiratory conditions
- Metabolic syndrome
- Sleep disorders
How to Get Qualified
There are two paths:
1. Through Your Own Doctor
Ask your primary care physician or specialist to write a Letter of Medical Necessity stating that a sauna is prescribed for your specific condition. Some doctors are familiar with this process; others may need to see the research supporting sauna use for your condition.
2. Through TrueMed
The easier route for most people. TrueMed is a platform that connects you with licensed healthcare providers who evaluate your eligibility for HSA/FSA coverage of wellness products including saunas. The process is done online, takes about 15 minutes, and if you qualify, you receive your LMN immediately. SweatDecks has partnered with TrueMed to streamline this process.
The Math
Using pre-tax dollars effectively gives you a discount equal to your marginal tax rate. If you're in the 25% tax bracket and buy a $5,000 sauna with HSA funds, you save $1,250 in taxes. At the 32% bracket, that's $1,600 in savings on the same purchase.
Important Notes
- The LMN must be obtained before or at the time of purchase
- Keep your LMN and receipt - the IRS can audit HSA/FSA expenditures
- FSA funds typically expire at year-end, so plan your timing accordingly
- Not every condition qualifies - the provider must determine medical necessity for your specific situation
