Guide to Health Savings Account (HSA)
What is an HSA?
A Health Savings Account (HSA) is a special savings account in the US that allows you to save for medical expenses with tax advantages. To qualify for an HSA, you must have a High Deductible Health Plan (HDHP) insurance. HSA funds can be used for qualified medical expenses including doctor visits, dental care, vision care, and prescription medications. Unlike FSAs, HSA funds don't expire at year end and can be invested.
Tax benefits of HSA
HSA offers triple tax advantage: contributions are tax-deductible (reduce taxable income), growth is tax-free, and withdrawals for qualified medical expenses are tax-free. In 2024, the maximum annual HSA contribution is $4,150 for individual coverage and $8,300 for family coverage. If your employer offers HSA, they may also make contributions, increasing your tax savings.
Eligibility and requirements
To be eligible for HSA, you must have a qualifying HDHP insurance with a minimum deductible of at least $1,500 for individual coverage or $3,000 for family coverage in 2024. You cannot be covered by other health insurance (except for specific accident, dental, vision, or long-term care insurance). Individuals aged 55+ can make additional catch-up contributions of $1,000 per year.
Investing HSA funds
Once you reach a certain balance in your HSA (typically around $1,000-$2,000), many financial institutions allow investing excess funds in index funds, ETFs, or other investment vehicles. This allows for further growth in a tax-free manner. Consider treating HSA as a long-term retirement account for medical expenses, as after age 65 you can withdraw funds for any purpose (but taxed as ordinary income).
HSA maximization strategy
The best strategy is to treat HSA as a "third" retirement account alongside 401(k) and IRA. If you can afford it, maximize HSA contributions, then invest the excess. When you need funds for current medical expenses, you can withdraw them provided you keep receipts to cover costs. This way you build savings for future medical expenses or preserve financial flexibility in retirement.
