Understanding HSAs and FSAs

Both Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs) allow you to use pre-tax dollars to pay for medical expenses, helping to reduce your taxable income. While they share this goal, they differ in terms of eligibility, contribution limits, and flexibility.

Health Savings Account (HSA)

An HSA is a personal savings account paired with a high-deductible health plan (HDHP) that offers three key tax advantages:

  1. Contributions are tax-deductible, even if you don’t itemize.
  2. Earnings grow tax-free.
  3. Withdrawals for qualified medical expenses are tax-free.

2025 Contribution and Eligibility Limits

  • Individual coverage: $4,300
  • Family coverage: $8,550
  • Catch-up contribution (age 55 or older): Additional $1,000

To be eligible for an HSA, you must be enrolled in a high-deductible health plan:

  • Minimum deductible: $1,650 (self-only), $3,300 (family)
  • Maximum out-of-pocket: $8,300 (self-only), $16,600 (family)

Benefits of an HSA

  • Contributions lower your taxable income.
  • Funds roll over year to year—no “use it or lose it.”
  • After age 65, withdrawals for non-medical expenses are allowed without penalty (though taxed as income).
  • HSA funds can be invested for long-term growth.
  • As of 2025, certain direct primary care (DPC) fees may qualify as eligible expenses under new IRS guidance.

Flexible Spending Account (FSA)

An FSA is an employer-sponsored account that allows employees to set aside pre-tax income for qualifying medical or dependent care expenses. FSAs are typically offered as part of an employer’s benefits package.

2025 Contribution Limits and Rules

  • Health FSA: $3,300
  • Carryover: Up to $660 may be rolled over into the following plan year if permitted by the employer
  • Dependent Care FSA: $5,000 per household ($2,500 if married filing separately)

Features of an FSA

  • Reduces your taxable income through payroll deductions.
  • Full annual contribution is available at the beginning of the plan year.
  • Funds are generally forfeited if not used by the end of the plan year, unless a carryover or grace period is offered.
  • FSAs are not portable—you lose access to unused funds when leaving your employer unless you qualify for COBRA continuation under specific conditions.

Strategic Use of HSAs and FSAs

1. Maximize HSA Contributions

If you are eligible, contribute the full amount to your HSA. It offers unmatched tax advantages and can serve as a supplemental retirement savings tool.

2. Use FSAs for Predictable Expenses

FSAs are well-suited for known, recurring expenses like prescriptions, medical copays, dental treatments, and eyeglasses. Estimate your needs carefully to avoid forfeiting unused funds.

3. Combine Wisely (if Allowed)

Some employers offer both accounts in a limited FSA + HSA format, where the FSA is used for dental and vision expenses only. This combination can help you maximize pre-tax savings without overlapping eligibility.

4. Invest HSA Funds for the Long Term

If you can pay for current medical expenses out of pocket, consider investing your HSA funds. Keep receipts, as you can reimburse yourself later—even years down the line.

5. Take Advantage of Catch-Up Contributions

At age 55 and older, both spouses can contribute an extra $1,000 each to their own HSAs if they have separate accounts. This helps accelerate savings before retirement.

6. Stay Aware of Plan Details

FSAs require annual re-enrollment and may have employer-specific rules regarding carryovers or grace periods. Review your benefits each year to make the most of what’s offered.

Tax Reporting and Compliance

  • HSA contributions must be reported on IRS Form 8889.
  • Employer and employee contributions count toward the annual limit.
  • FSA contributions are generally managed through payroll and reported on your W-2.
  • Keep documentation of all medical expenses in case of IRS review.

Final Takeaways

HSAs and FSAs provide powerful opportunities to lower taxable income and plan for both short- and long-term healthcare costs. While FSAs are designed for current year medical needs, HSAs can serve as a hybrid of health and retirement planning. Using both effectively requires a clear understanding of the eligibility rules, contribution limits, and how each account aligns with your overall financial plan.

Consult with a tax advisor or benefits specialist to determine which account(s) best suit your health coverage and financial goals, particularly if your circumstances involve employer changes, retirement planning, or complex medical needs.
