What Is an HSA?
A Health Savings Account (HSA) is a tax-advantaged savings account available to individuals enrolled in a High Deductible Health Plan (HDHP). HSAs let you save pre-tax dollars for qualified medical expenses — and unlike FSAs, unused funds roll over indefinitely and can be invested for long-term growth.
After age 65, HSA funds can be withdrawn for any purpose without penalty (though non-medical withdrawals are taxed as ordinary income, similar to a Traditional IRA).
2026 HSA Contribution Limits
| Coverage Type | Annual Limit | With Catch-Up (55+) |
|---|---|---|
| Self-Only | $4,400 | $5,400 |
| Family | $8,750 | $9,750 |
Eligible individuals age 55 or older by year-end can make an additional contribution of up to $1,000. It reached $1,000 in 2009 and is not indexed for inflation. If both spouses qualify, each makes their catch-up to their own HSA.
2026 HDHP Requirements
You generally need qualifying high-deductible coverage, no disqualifying coverage and no Medicare enrollment. You cannot be claimed as a dependent on someone else’s return. These are the general 2026 HDHP thresholds.
| Requirement | Self-Only | Family |
|---|---|---|
| Minimum Annual Deductible | $1,700 | $3,400 |
| Maximum Out-of-Pocket | $8,500 | $17,000 |
Out-of-pocket maximums include deductibles, copayments and coinsurance. They exclude premiums, and the rule for network plans generally excludes out-of-network costs. Starting in 2026, eligible individual-market bronze and catastrophic plans may be treated as HDHPs even if they miss the general limits. See IRS Notice 2026-5 for plan and direct-primary-care rules.
HSA Triple Tax Advantage
The HSA is the only account in the U.S. tax code that offers a triple tax benefit:
Contributions reduce your taxable income. Payroll contributions also avoid FICA taxes (7.65%).
Interest, dividends, and investment gains inside the HSA are never taxed while they remain in the account.
Withdrawals for qualified medical expenses are 100% tax-free at any age, with no required minimum distributions.
Key Dates & Deadlines
Contribution Deadline: You have until April 15, 2027 (the federal tax filing deadline) to make HSA contributions for the 2026 tax year.
Payroll Contributions: Employer payroll deductions for HSA must occur during the 2026 calendar year (January 1 – December 31, 2026).
Last-Month Rule: If you become HSA-eligible on December 1, 2026, you can contribute the full annual limit — but you must remain HDHP-eligible through December 31, 2027 (the testing period) or face taxes and a 10% penalty on the excess.
Age 65 Medicare: Once enrolled in Medicare, you can no longer contribute to an HSA. However, you can still use existing HSA funds tax-free for qualified medical expenses, including Medicare premiums (Parts B, C, and D).
