2026 HSA limits
| Self-only | Family | |
|---|---|---|
| Contribution limit (you and employer together) | $4,400 | $8,750 |
| Catch-up, age 55 and over | +$1,000 | +$1,000 each eligible spouse |
| High-deductible plan: minimum deductible | $1,700 | $3,400 |
| High-deductible plan: maximum out-of-pocket | $8,500 | $17,000 |
You can contribute for 2026 until the tax filing deadline in April 2027. Employer contributions count toward the limit. A spouse's $1,000 catch-up must go into their own HSA. Once you enroll in Medicare you can no longer contribute, though you can keep using the money.
Who can have an HSA in 2026
You need a high-deductible health plan and no other disqualifying coverage. The 2025 tax law widened this from January 1, 2026: bronze and catastrophic plans now count as HSA-compatible, whether or not they meet the usual deductible rules, and even if bought outside an Exchange. People with a direct primary care arrangement costing up to $150 a month ($300 for more than one person) can now contribute and pay those fees from the HSA. Telehealth before the deductible is now permanently allowed.
The triple tax advantage
Contributions through payroll avoid federal income tax, Social Security and Medicare tax, and in most states state income tax. Contributions you make directly are deducted on your tax return, which saves income tax but not the 7.65% payroll tax. Growth is untaxed, and withdrawals for qualified medical expenses are tax-free at any age. California and New Jersey do not follow these rules, so residents there pay state tax on contributions and growth.
A single filer earning $75,000 who puts $4,400 in through payroll saves $968 of federal income tax (22%) and $336.60 of payroll tax, $1,304.60 in all, before any state tax saving. Invested at 6% every year for 25 years, $4,400 a year grows to about $255,900.
Spending it vs investing it
Most people use their HSA like a checking account for doctor bills. If you can afford to pay medical costs from your pocket, a stronger strategy is to invest the HSA and keep your receipts: there is no time limit on reimbursing yourself, so you can withdraw tax-free years later for expenses paid today. After 65 you can also withdraw for any purpose without penalty, paying ordinary income tax like a traditional IRA. Before 65, non-medical withdrawals are taxed and charged a 20% penalty.
Many HSA providers keep the first $1,000 to $2,000 in cash and charge account fees; compare investment options and fees before you choose, and you can move the money to a different HSA provider at any time.
