HSA Contribution Limits 2026 and 2027
Both years are now set. For 2027, the IRS annual HSA contribution limit is $4,500 for self-only coverage (up $100) and $9,000 for family coverage (up $250), confirmed in Revenue Procedure 2026-24 on 29 May 2026. For 2026, the limits are $4,400 self-only (up from $4,300 in 2025) and $8,750 family (up from $8,550). The catch-up contribution for anyone 55 or older stays at $1,000 in both years, because it is fixed in statute and not indexed to inflation. To qualify, your plan must be an HDHP with a minimum deductible of $1,700 self / $3,400 family in 2026, rising to $1,750 / $3,500 in 2027, and out-of-pocket maximums no higher than $8,500 / $17,000 in 2026 and $8,700 / $17,400 in 2027.

The HSA Triple Tax Advantage
HSAs are the only account in the US tax code with three simultaneous tax advantages. No other retirement or savings vehicle — not the 401(k), not the Roth IRA, not a 529 — offers all three:
Tax-Deductible In
Contributions reduce your taxable income dollar-for-dollar — like a 401(k) but no employer needed.
Tax-Free Growth
Invest your HSA in index funds. All growth, dividends, and capital gains are completely tax-free.
Tax-Free Out
Withdraw for any qualified medical expense totally tax-free. After 65, use for anything (taxed like 401k).
Eligible for Only Part of 2026? Prorate It
HSA eligibility is tested monthly, on the first day of each month — so a partial year gives you a partial limit. Take one twelfth of the annual amount for every month you were eligible. If your coverage switched type mid-year, prorate each stretch separately and add them together.
| Months eligible in 2026 | Self-only | Family |
|---|---|---|
| 3 | $1,100 | $2,188 |
| 6 | $2,200 | $4,375 |
| 9 | $3,300 | $6,563 |
| 12 (full year) | $4,400 | $8,750 |
Table figures are rounded to the nearest dollar; the exact monthly fraction is what the IRS uses. Monthly building blocks for 2026: $366.67 self-only, $729.17 family, $83.33 for the age-55 catch-up. Example of a mid-year switch: five months self-only plus seven months family is (5 × $366.67) + (7 × $729.17) = $6,937.50.
The Last-Month Rule — and the 13-Month Catch
If you are HSA-eligible on 1 December 2026, you may contribute the full annual limit for 2026 — $4,400 or $8,750 — regardless of how few months you were actually covered. In exchange you take on the testing period: you must stay HDHP-covered and HSA-eligible through 31 December 2027.
Fail it for any reason other than death or disability and the amount above your prorated limit is added back to your gross income in the year you fail, plus an additional 10% tax. It is a good deal if you are confident about the next 13 months, and a trap if you are about to change jobs, retire, or start Medicare.
Married Couples Share One Family Limit
If either spouse has family HDHP coverage and both are eligible, you share one $8,750 limit between you — not $8,750 each. Split it in whatever proportion you agree, and remember employer contributions to either spouse count against the same cap. The one exception is the age-55 catch-up: it is per person and must go into that person's own HSA, so two spouses over 55 can add $1,000 each but cannot stack both into one account. Each spouse contributing the full family limit is a common mistake and creates an excess contribution taxed at 6% for every year it stays in the account.
Frequently Asked Questions
What is the HSA contribution limit for 2026?▼
For 2026, the IRS HSA contribution limit is $4,400 for self-only HDHP coverage and $8,750 for family HDHP coverage, up from $4,300 and $8,550 in 2025. If you are age 55 or older, you may contribute an additional $1,000 catch-up contribution, raising the self-only limit to $5,400 and the family limit to $9,750. Employer contributions count toward these limits. Source: IRS Rev. Proc. 2025-19.
What if I was only eligible for part of 2026? How is the HSA limit prorated?▼
HSA eligibility is determined monthly, on the first day of each month, so a partial year gives you a partial limit: one twelfth of the annual amount for each month you were eligible. For 2026 that is $366.67 per month of self-only coverage, $729.17 per month of family coverage, and $83.33 per month of the age-55 catch-up. Someone who starts HDHP family coverage on 1 July 2026 is eligible for six months and can contribute 6 x $729.17 = $4,375. If your coverage changes type mid-year, you prorate each part separately — five months of self-only plus seven months of family is (5 x $366.67) + (7 x $729.17) = $6,937.50. The alternative is the last-month rule, which can let you contribute the full annual amount instead. Source: IRS Publication 969 and the Form 8889 instructions.
What is the HSA last-month rule, and what is the testing period?▼
If you are HSA-eligible on 1 December, the last-month rule lets you contribute the FULL annual limit for that year — $4,400 self-only or $8,750 family for 2026 — even if you were only eligible for part of it. The catch is the testing period: you must remain an eligible individual, covered by an HDHP, through 31 December of the FOLLOWING year. For a 2026 contribution that means staying eligible all the way through 31 December 2027. If you fail the testing period for any reason other than death or disability, the amount you contributed above the prorated limit is added back to your gross income in the year you fail, and it is hit with an additional 10% tax on top. That makes the last-month rule a genuinely good deal for someone confident about the next 13 months, and a trap for someone about to change jobs, retire, or go onto Medicare. Source: IRS Publication 969.
How does the HSA limit work for married couples?▼
If either spouse has family HDHP coverage and both are HSA-eligible, the couple shares ONE family limit — $8,750 for 2026, not $8,750 each. You may divide that total between your two HSAs in any proportion you agree on, and employer contributions to either spouse count against the same shared cap. The exception is the age-55 catch-up, which is per person and must be paid into that person's OWN HSA: two spouses both aged 55 or over can add $1,000 each, but they cannot stack both catch-ups into a single account. A common and expensive mistake is each spouse contributing the full family limit, which creates an excess contribution subject to a 6% excise tax for every year it is left in the account. Source: IRS Publication 969.
What are the HDHP minimum deductible amounts for 2026?▼
To be eligible for an HSA in 2026, you must be enrolled in a High Deductible Health Plan (HDHP). The minimum annual deductible is $1,700 for self-only coverage and $3,400 for family coverage (up from $1,650 / $3,300 in 2025). The maximum out-of-pocket limit is $8,500 (self-only) and $17,000 (family) (up from $8,300 / $16,600 in 2025). Source: IRS Rev. Proc. 2025-19.
Can I use my HSA as a retirement account?▼
Yes. After age 65, HSA withdrawals for non-medical expenses are subject to ordinary income tax (like a 401k) — but no penalty. Withdrawals for qualified medical expenses remain completely tax-free at any age. This makes HSAs the only account in the US tax code with three tax benefits: tax-deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses.
Which states don't recognize HSA tax benefits?▼
California and New Jersey do not conform to federal HSA rules at the state level. Residents of these states still receive the federal income tax deduction, but HSA contributions are subject to state income tax, and investment growth within the HSA is also taxable at the state level.
Did HSA limits increase from 2025 to 2026?▼
Yes. The self-only limit increased from $4,300 in 2025 to $4,400 in 2026 (a $100 increase). The family limit increased from $8,550 in 2025 to $8,750 in 2026 (a $200 increase). The catch-up contribution remained unchanged at $1,000. Source: IRS Rev. Proc. 2025-19.
