HSA Day, held every year on October 15, is a day dedicated to promoting education and appropriate use of HSAs. It’s a chance to learn more about how to use your HSA and plan for a healthy future (and enjoy some special savings—more on this below).
Here’s a closer look at HSA Day, including the best ways to celebrate it.
Why HSA Day is important
The number of Americans with HSAs is rapidly growing. But many of these people might not be taking full advantage of their accounts.
HSA accounts increased from 6.3 million in 2011 to nearly 40 million by 2025. At the same time, a Greenwald Research survey found that only 47% of HSA enrollees knew that HSAs could be used for medical expenses in retirement. Only 28% knew that HSA funds could be invested in mutual funds.
HSA Day aims to help close this knowledge gap, so holders can maximize their accounts. Awareness of basic HSA rules, tax advantages, and eligible expenses helps you plan for short- and long-term health goals.
If you’re deciding whether to open an HSA during open enrollment, exploring resources and tools during HSA Day can also help you make an informed decision.
What is an HSA?
To quickly review: An HSA is a personal healthcare account that you fund and use to cover qualifying health products and services. To enroll in an HSA, you must have a qualified high-deductible health plan.
HSAs enjoy a “triple tax advantage”:
- HSA contributions aren’t taxed.
- There’s no tax on interest earned or growth from invested HSA funds.
- There’s no tax on HSA withdrawals for qualified health expenses.
For expenses to be HSA eligible, they must meet the IRS’s definition of medical care. The IRS defines medical expenses as amounts paid for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for the purpose of affecting any structure or function of the body.
