HSA Contribution Limits 2027: $4,500 Self-Only, $9,000 Family

Quick answer: For 2027, you can put up to $4,500 in a health savings account (HSA) with self-only coverage, or $9,000 with family coverage. That’s up from $4,400 and $8,750 in 2026. If you’re 55 or older, you can add a $1,000 catch-up. To qualify, your high-deductible health plan (HDHP) needs a deductible of at least $1,750 (self-only) or $3,500 (family) in 2027. The IRS set these numbers in Revenue Procedure 2026-24.

An HSA is one of the few accounts with three tax breaks. Money goes in tax-free, grows tax-free and comes out tax-free for medical bills. If you have an HDHP at work or through the Marketplace, open enrollment is the right time to plan how much to save next year.

The $1,000 catch-up is not adjusted for inflation. It has been $1,000 for years and stays there in 2027.

How to max out your HSA in 2027: step by step

1. Confirm your plan is HSA-eligible. Ask HR or check your plan documents for “HSA-qualified HDHP.” The deductible must meet the 2027 minimums above.
2. Pick your coverage type. Self-only means $4,500. Any family tier (you plus one or more) means $9,000.
3. Subtract your employer’s contribution. Employer money counts toward the same limit. If your boss puts in $1,000 on self-only coverage, you can add up to $3,500.
4. Divide by your pay periods. With 26 paychecks, $4,500 is about $173 per check. Payroll contributions also skip Social Security and Medicare taxes.
5. Add the catch-up if you’re 55+. That’s an extra $1,000, or about $38 per paycheck.
6. Invest what you won’t spend soon. Many HSAs let you invest in funds once you keep a minimum cash balance.

Who can contribute to an HSA?

You can contribute for a month only if, on the first day of that month, all of these are true:

• You’re covered by an HSA-eligible HDHP.
• You have no other disqualifying health coverage, such as a regular health plan through a spouse.
• You’re not enrolled in Medicare.
• No one can claim you as a dependent on their tax return.

A general-purpose health FSA, including a spouse’s, usually blocks HSA contributions. A limited-purpose FSA for dental and vision does not.

The triple tax break, in dollars

Here’s what an HSA can save you, using rough numbers. Say you’re in the 22% federal bracket and put $4,500 in through payroll.

• Federal income tax saved: about $990 (22% of $4,500).
• Social Security and Medicare tax saved: about $344 (7.65% of $4,500), only for payroll contributions.
• State income tax: most states also exempt HSA money, but California and New Jersey tax HSA contributions at the state level.

These are estimates. Your savings depend on your tax bracket and state.

Important dates and deadlines

You can still add money for 2026 until the April 2027 tax deadline. If you didn’t max out this year, that’s a quick win.

What you can spend HSA money on

Qualified medical expenses include doctor visits, prescriptions, dental work, glasses, contacts, hearing aids and many over-the-counter medicines. Menstrual care products also count. IRS Publication 502 has the full list.

You don’t have to pay yourself back right away. Save your receipts, and you can reimburse yourself years later, tax-free, as long as the expense came after you opened the HSA.

Mistakes to avoid

• Going over the limit. Excess contributions face a 6% excise tax each year they stay in the account. Remove the extra (and any earnings) before your tax deadline.
• Forgetting your employer’s share. It counts toward the $4,500 or $9,000.
• Contributing after Medicare starts. Once you enroll in Medicare, including Part A, you can’t add new money. Medicare Part A can be backdated up to 6 months when you sign up after 65, so stop contributions 6 months before you apply.
• Using it for non-medical costs before 65. That money is taxed and hit with a 20% penalty. After 65, non-medical withdrawals are taxed like income but without the penalty.
• Leaving it all in cash. Long-term money in cash may lose value to inflation.

What if you change plans mid-year?

If you’re HSA-eligible for only part of 2027, your limit is usually prorated by month. For example, 6 months of self-only eligibility means about $2,250.

The “last-month rule” lets you contribute the full year’s amount if you’re eligible on Dec. 1. But you must stay eligible through the next full year (the testing period). If you don’t, the extra becomes taxable plus a 10% additional tax.

HSA vs. FSA: which is better?

If you’re healthy and can cover the higher deductible, an HSA is often the better long-term deal. If you expect big medical bills and want a low deductible, a traditional plan with an FSA may cost less.

Is an HDHP with an HSA right for you?

An HSA only works with a high-deductible plan, so the real question is whether that plan fits your family. Ask yourself:

• Can you cover the deductible from savings? In 2027 that’s at least $1,750 for one person or $3,500 for a family, and many plans are higher.
• How often do you see doctors? If you mostly need checkups, an HDHP often costs less. Preventive care is usually covered before the deductible.
• Do you take costly prescriptions? You may pay full price until you hit the deductible. Compare total yearly costs, not just premiums.
• Does your employer add money? An employer HSA deposit can make an HDHP clearly cheaper.

A quick way to compare: add up a year of premiums plus the most you could pay out of pocket for each plan. Then subtract any employer HSA deposit and your tax savings from the HDHP side.

Where to open an HSA

If your employer offers an HSA, use it for payroll deductions so you save on Social Security and Medicare taxes. You can later move the money to another HSA provider with lower fees or better investments through a trustee-to-trustee transfer, which isn’t taxed and isn’t limited to once a year.

If you buy your own HDHP, you can open an HSA at many banks and brokerages. Look for no monthly fee, low-cost index funds and a low (or no) cash minimum before you can invest.
