HSA

An HSA (Health Savings Account) is a savings account available to people enrolled in high-deductible health insurance plans. It offers a unique “triple tax advantage”: contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free.

How it works

An HSA is available only if you are enrolled in a high-deductible health plan (HDHP). For 2024, an HDHP has a minimum deductible of $1,600 (individual) or $3,200 (family).

You contribute pre-tax income to an HSA (either through payroll deduction or directly to the account). You use the HSA to pay qualified medical expenses: deductibles, copays, dental, vision, prescription drugs, and thousands of other medical costs.

Key advantage: withdrawals for qualified medical expenses are tax-free and penalty-free, making this the only way to use pre-tax dollars for healthcare costs (outside of employer-provided health plans).

The triple tax advantage

1. Contributions are tax-deductible. You reduce your taxable income.
2. Growth is tax-free. The account earns interest and investment returns without annual tax.
3. Withdrawals for medical are tax-free. You never pay tax on the money used for healthcare.

This is superior to paying for medical costs with after-tax dollars (no deduction, tax on growth, no refund on use).

Investment within HSA

Unlike a flexible spending account (FSA), an HSA can be invested like a 401(k). Many HSA providers offer mutual funds, index funds, and other investments. You can let the money grow for decades instead of using it immediately.

This is why HSAs are popular among affluent people and early retirees: the triple tax advantage and investment potential make them the most efficient place to save for healthcare costs.

Qualified medical expenses

Covered expenses include:

• Medical deductibles and copays
• Dental work (fillings, cleanings, orthodontics)
• Vision (exams, glasses, contacts)
• Prescription drugs
• Mental health care
• Physical therapy
• Hearing aids and medical equipment
• Many others (IRS has a full list)

Not covered: cosmetic procedures, over-the-counter medications (as of 2011), or insurance premiums (except COBRA continuation coverage and long-term care insurance).

HDHP tradeoff

The catch: to be HSA-eligible, you must enroll in an HDHP, which has higher deductibles ($1,600+) than a traditional plan. This is a tradeoff: you save on premiums and get an HSA, but you absorb more upfront medical costs.

For people with low medical expenses, an HDHP + HSA is often the best economic choice. For people with chronic conditions requiring frequent care, a traditional plan may be better despite the lack of HSA.

Unused balance and rollover

An HSA is uniquely yours. Unlike an FSA, which has a “use-it-or-lose-it” rule, HSA balances roll over indefinitely. If you do not spend the money, it remains in the account to invest and grow.

This encourages using the HSA as a retirement healthcare savings vehicle: contribute the maximum, invest it, and withdraw only for actual medical expenses in retirement.

HSA in retirement

An HSA is particularly valuable in retirement for two reasons:

1. Healthcare costs. Healthcare expenses escalate in age. A large HSA balance can cover many retirement medical costs tax-free.
2. Post-65 flexibility. After age 65, you can withdraw HSA money for any purpose without the 20% penalty (though non-medical withdrawals are taxable). This makes an HSA function like a 401(k) or IRA in retirement.

This is why some financial advisors treat the HSA as a retirement account first and a healthcare account second: max it out, invest it, and use other assets to pay medical expenses during working years.

Portability

An HSA is fully portable. If you change jobs or change health insurance plans (but stay in an HDHP), you keep the HSA and can continue to use it. This is unique to HSAs among benefit accounts.
