Learn About Health Savings and Flexible Spending Accounts

Understanding Health Savings Accounts (HSAs)

A Health Savings Account, or HSA, is a special savings account designed to work alongside a high-deductible health plan (HDHP). Unlike a regular bank account, money deposited into an HSA receives special tax treatment from the federal government. Contributions reduce your taxable income, the account grows tax-free, and withdrawals for medical expenses are not taxed. This triple tax advantage makes HSAs distinct from other savings vehicles.

To use an HSA, you must be enrolled in a qualifying high-deductible health plan. In 2024, the IRS defines an HDHP as a plan with a deductible of at least $1,600 for individual coverage or $3,200 for family coverage. The maximum out-of-pocket limits are $8,050 for individual coverage and $16,100 for family coverage in 2024. These numbers change annually. You cannot have other health coverage, such as Medicare or a spouse's non-HDHP plan, and still contribute to an HSA.

Contribution limits vary by year and coverage type. In 2024, individuals can contribute up to $4,150 annually to an HSA, while families can contribute $8,300. People age 55 and older may make an additional catch-up contribution of $1,000 per year. These limits are set by the IRS and typically increase each year to account for inflation.

The funds in an HSA belong to you and roll over year to year—there is no "use it or lose it" rule like some other health accounts. This means you can accumulate funds over time and use them in future years. Some people treat HSAs as long-term retirement savings vehicles, allowing the account to grow substantially over decades. HSA funds can be invested in mutual funds, stocks, or bonds at many financial institutions, similar to a retirement account.

Practical Takeaway: HSAs work best for people enrolled in high-deductible health plans who have the financial ability to pay current medical costs from other sources and want to save for future healthcare expenses. Understanding the annual contribution limits and deductible thresholds helps you determine whether an HSA fits your financial situation.

Qualifying Medical Expenses for HSAs

HSA funds can pay for a wide range of medical, dental, and vision expenses. The IRS maintains a detailed list of what counts as a qualified medical expense. Some obvious expenses include doctor visits, hospital stays, prescription medications, and surgery. However, the definition is much broader than many people realize. Understanding what qualifies helps you make informed decisions about which expenses to pay from your HSA and which to pay from other sources.

Dental care is a major category of qualified expenses. Routine cleanings, fillings, root canals, crowns, braces, and dentures all qualify. Vision care is similarly covered—eye exams, glasses, contact lenses, and laser eye surgery are all qualified expenses. Mental health care, including therapy and psychiatrist visits, qualifies as a medical expense. Prescription medications are covered, as are many over-the-counter medications when prescribed by a doctor (though general over-the-counter medications purchased without a prescription do not qualify under current rules).

Less obvious qualified expenses include certain medical equipment and supplies. Crutches, wheelchairs, hearing aids, and blood glucose monitors all qualify. Insulin and supplies related to managing chronic conditions are covered. Physical therapy, acupuncture, and chiropractic care may qualify in some cases. Medical alert systems and mobility aids for people with disabilities are also included. Additionally, long-term care insurance premiums and certain Medicare premiums can be paid with HSA funds.

Some expenses that are NOT qualified include general wellness programs, cosmetic procedures, teeth whitening (unless medically necessary), and over-the-counter medications purchased without a prescription. Hair transplants, gym memberships, and weight loss programs do not qualify unless specifically prescribed by a physician as treatment for a medical condition. It's important to keep receipts and documentation for all HSA withdrawals, as the IRS may request proof that expenses were medically necessary.

Practical Takeaway: Review the IRS's detailed list of qualified medical expenses before opening an HSA or making withdrawals. Keeping organized records of medical expenses throughout the year helps you plan which costs to pay from your HSA and ensures you can document expenses if questions arise.

How Flexible Spending Accounts (FSAs) Work

A Flexible Spending Account (FSA) is a workplace benefit that allows employees to set aside pre-tax money to pay for medical and dependent care expenses. Like an HSA, FSA contributions reduce your taxable income. However, FSAs operate differently from HSAs in important ways. FSAs are offered by employers, not opened independently by individuals. Money deposited into an FSA is set aside through payroll deductions before taxes are calculated, reducing both federal income tax and payroll taxes.

There are two main types of FSAs: healthcare FSAs and dependent care FSAs. A healthcare FSA covers medical, dental, vision, and pharmacy expenses. A dependent care FSA covers childcare and adult daycare expenses for dependents. Some employers offer both types, allowing employees to have separate accounts for each purpose. Enrollment typically occurs during an employer's open enrollment period, usually once per year, and elections take effect on January 1st.

The FSA contribution limit for 2024 is $3,300 per person per year for healthcare FSAs. Dependent care FSAs have a different limit of $5,000 per year for single filers and married couples filing jointly, or $2,500 for married individuals filing separately. These limits reset each January 1st. Unlike HSAs, FSA funds do not roll over indefinitely. There is a "use it or lose it" rule: money not spent by the end of the plan year is forfeited.

However, employers may offer a grace period or carryover provision. A grace period allows employees to spend funds from the previous year's account during the first two and a half months of the new year. Carryover allows up to $640 of unused funds to roll into the next year (in 2024). These options vary by employer plan. Employees should check their specific plan documents to understand whether their FSA offers either of these features.

Practical Takeaway: When enrolling in an FSA, estimate your annual medical or dependent care expenses carefully. Setting aside too much money risks forfeiting unused funds at year-end. Talk to your employer's benefits administrator about whether your plan offers a grace period or carryover option, as this affects how much you can safely contribute.

Key Differences Between HSAs and FSAs

While both HSAs and FSAs offer tax advantages for healthcare expenses, they have distinct features that make each suitable for different situations. Understanding these differences helps you determine which account type, or both, might work for your needs. The comparison centers on ownership, funding, contribution limits, rollover rules, investment options, and employer involvement.

Ownership is perhaps the most significant difference. HSAs are owned by the individual and belong to you even if you change jobs. Once you open an HSA, the account remains yours for life, and you control how much to contribute each year (within IRS limits). FSAs, by contrast, are owned by the employer. If you leave your job, your FSA account ends, though you may be able to use remaining funds through COBRA continuation coverage. This difference means HSAs offer more portability and long-term control over your healthcare savings.

Funding mechanisms differ as well. HSAs can be funded by employees, employers, or both. You can open an HSA independently if you have an HDHP, even if your employer doesn't offer one. Employers offering HSAs may contribute to employee accounts as part of their benefits package. FSAs, however, are only workplace-based. Your employer must offer an FSA for you to have one; you cannot open an FSA on your own. FSA contributions come only from your paycheck through payroll deductions.

The rollover rules create practical differences in planning. HSA funds roll over indefinitely with no penalty, allowing you to accumulate savings over many years. Some people use HSAs as retirement savings vehicles after age 65, when non-medical withdrawals are allowed (though they're taxed like regular income). FSA funds follow the "use it or lose it" rule, though employers may offer grace periods or carryover options. This means FSAs reward spending your money within the plan year or planning period.
