The IRS has already confirmed the 2027 Health Savings Account (HSA) limits: you will be able to contribute up to $4,500 with self-only coverage and $9,000 with family coverage. That is $100 and $250 more than in 2026. Unlike 401(k) limits, which the IRS usually announces in the fall, these figures are official now, so you can plan your open-enrollment choices around them.
The numbers are the easy part. The mistakes that actually cost people money come from the rules around them: who counts as eligible, how employer contributions eat into your limit, and what happens if your coverage changes mid-year. This guide covers both.
2027 HSA limits at a glance
The IRS published the 2027 amounts in Revenue Procedure 2026-24 on May 29, 2026. Here is how they compare with 2026:
| Item | 2026 | 2027 | Change |
|---|---|---|---|
| Contribution limit, self-only | $4,400 | $4,500 | +$100 |
| Contribution limit, family | $8,750 | $9,000 | +$250 |
| Minimum HDHP deductible, self-only | $1,700 | $1,750 | +$50 |
| Minimum HDHP deductible, family | $3,400 | $3,500 | +$100 |
| HDHP out-of-pocket maximum, self-only | $8,500 | $8,700 | +$200 |
| HDHP out-of-pocket maximum, family | $17,000 | $17,400 | +$400 |
People age 55 and older who are not enrolled in Medicare can add a $1,000 catch-up contribution. If both spouses are 55 or older, each can make a separate $1,000 catch-up, but each must contribute it to their own HSA.
Who can contribute to an HSA
You can contribute for a given month only if you meet all of these conditions:
- You are enrolled in an HSA-eligible high-deductible health plan (HDHP). The plan must meet the minimum deductible and out-of-pocket maximum above.
- You are not enrolled in Medicare, Medicaid, TRICARE, or CHIP.
- You are not claimed as a dependent on someone else’s tax return.
- You do not have a general-purpose health care FSA. A limited-purpose FSA (for example, dental and vision only) is allowed.
The HDHP requirement is the one people miss. Not every plan with a high deductible qualifies, so check with your insurer or HR that your specific plan is HSA-eligible before you count on the tax break.
Why the HSA is called triple tax-advantaged
According to the IRS, contributions you make yourself are deductible whether or not you itemize, contributions your employer makes are not taxed as income to you, earnings inside the account grow without tax, and withdrawals for qualified medical expenses are tax-free. Few other accounts stack all three.
Here is a simple illustration, not a prediction. If you contribute the full $4,500 self-only limit and you are in the 22% federal income tax bracket, the deduction is worth roughly $990 in federal income tax that year. Your state may treat HSAs differently, since a small number of states do not follow the federal tax treatment, so check your state’s rules. To see where bracket thresholds are heading, our guide to 2027 tax brackets, what is confirmed and what is projected shows the current picture.
Five rules that cause the most trouble
1. Employer contributions count toward your limit
Anything your employer puts into your HSA reduces the amount you can contribute yourself, dollar for dollar. If you have family coverage in 2027 and your employer contributes $1,500, you can add up to $7,500 on your own, not $9,000. Check your pay stub or benefits portal before you set your payroll contribution.
2. The last-month rule has a catch
If you are enrolled in an HSA-eligible plan on December 1, you can contribute the full annual maximum even if you were covered for only part of the year. The catch is a testing period: you must stay HSA-eligible through December 31 of the following year. If you do not, the extra amount becomes taxable income and is hit with a 10% additional tax. This matters most if you plan to switch jobs or move onto Medicare.
3. Medicare enrollment ends contributions
Once you are enrolled in Medicare, you can no longer contribute. You can still spend what is already in the account on qualified expenses. If you are approaching 65, look at your enrollment timing carefully, because Medicare Part A coverage can start earlier than you expect. Our ACA open enrollment 2027 guide covers the marketplace side of the fall decision, and the same open-enrollment window is when many employers ask you to pick your HSA contribution.
4. Non-medical withdrawals are expensive before 65
If you withdraw money for something other than a qualified medical expense, the amount is taxed as ordinary income, plus an additional 20% tax. After age 65, the additional 20% tax no longer applies, but ordinary income tax still does on non-medical withdrawals. Keep receipts for medical spending, because you are responsible for showing that a withdrawal was qualified.
5. You have until the tax deadline
You generally have until the federal tax filing deadline, typically mid-April, to make contributions for the prior year. When you contribute in that window, tell your HSA provider which tax year the deposit is for, so it is not applied to the wrong year.
How the HSA fits with your other retirement and tax planning
Many households treat the HSA as a second retirement account for medical costs, because unused balances roll over every year and do not expire. That is a planning choice, not a requirement, and it only makes sense if you can pay current medical bills from other funds. If you are also deciding how much to put into workplace plans, see our breakdown of 401(k) and IRA contribution limits for 2026 and 2027, which explains the confirmed and projected numbers side by side.
A quick checklist before open enrollment
- Confirm your plan is HSA-eligible and check its 2027 deductible against the new $1,750 / $3,500 minimums.
- Find out whether your employer contributes, and how much, then subtract it from your 2027 limit.
- Confirm you or your spouse do not have a general-purpose FSA that would block contributions.
- If you are 55 or older and not on Medicare, plan for the extra $1,000 catch-up.
- Set a payroll contribution you can sustain, and keep a folder of medical receipts.
Frequently asked questions
What is the HSA limit for 2027?
$4,500 for self-only coverage and $9,000 for family coverage, plus a $1,000 catch-up for eligible people 55 and older.
Do HSA funds expire at the end of the year?
No. Unlike many FSAs, HSA balances roll over and stay in your account, and the account belongs to you if you change jobs.
Can I contribute to an HSA and an FSA?
Not to a general-purpose health care FSA. A limited-purpose FSA, such as one restricted to dental and vision, is allowed alongside an HSA.
When does the IRS announce 401(k) limits for 2027?
The IRS usually announces them in the fall, often around mid-November, so those figures are still projections. HSA limits, by contrast, are already official.
