The IRS has set the 2027 HSA contribution limit at $4,500 for self-only high-deductible health plan coverage and $9,000 for family coverage, up from $4,400 and $8,750 in 2026, under Revenue Procedure 2026-24, released in May 2026. Anyone 55 or older can still add a $1,000 catch-up contribution on top of either cap. The dollar increase looks small, but it lands alongside a higher deductible floor and a higher out-of-pocket ceiling for the health plans that qualify you for an HSA in the first place, and both of those numbers matter more than the headline contribution figure once you actually run them against your own plan.
How Much Did the HSA Contribution Limit Actually Go Up for 2027?
Self-only coverage goes up by $100, from $4,400 to $4,500. Family coverage goes up by $250, from $8,750 to $9,000. Both are roughly 2 to 3% increases, in line with how the IRS indexes HSA limits to inflation each year under Section 223 of the tax code. The $1,000 catch-up contribution for people 55 and older doesn't move at all, because unlike the base limits, it's fixed by statute rather than indexed, a detail covered further down.
What HDHP Do You Actually Need to Qualify for an HSA in 2027?
To open or keep contributing to an HSA, your health plan has to meet the IRS's definition of a high-deductible health plan, and those thresholds are rising too. For 2027, the minimum annual deductible is $1,750 for self-only coverage and $3,500 for family coverage, up from $1,700 and $3,400 in 2026. The maximum out-of-pocket limit, meaning the most you can be required to pay in deductibles, copays, and coinsurance combined before the plan covers 100%, rises to $8,700 for self-only coverage and $17,400 for family coverage, up from $8,500 and $17,000. If your employer doesn't adjust your plan's deductible to at least the new floor, your plan can stop qualifying as an HDHP entirely, which would cut off new HSA contributions regardless of what the contribution limit itself allows.
How Much Extra Tax Savings Does the Higher Limit Actually Buy You?
Take a family maxing out the new $9,000 limit through payroll deduction, which is how most people fund an HSA. Payroll HSA contributions skip both federal income tax and the 7.65% FICA payroll tax, so at a 24% federal bracket, the tax savings on the full $9,000 works out to about $2,848.50, versus roughly $2,741.63 on the old $8,750 limit, a real difference of about $107 in that one year purely from the higher cap. If you instead contribute directly to your HSA outside of payroll and deduct it on your tax return, you only avoid income tax, not FICA, so the same $9,000 at 24% saves about $2,160, and the extra $250 in room by itself is worth $60. Either way, the number is modest on its own, but it compounds the same way every other tax-advantaged contribution does if you're investing the balance rather than spending it on current medical bills.
Does the 55-and-Older Catch-Up Contribution Change for 2027?
No. The $1,000 HSA catch-up contribution has been fixed at that exact number since 2009, and unlike the base contribution limits, Congress never wrote an inflation adjustment into that piece of the law. In today's dollars, that $1,000 buys meaningfully less than it did when the number was set, and there's no indication that's changing for 2027. If you're 55 or older, it's still worth claiming, it's just worth knowing it's been quietly losing real value for over a decade while the base limits around it keep climbing.
What Should You Actually Do Before Open Enrollment?
Check your plan's actual 2027 deductible and out-of-pocket maximum against the new HDHP floors above, not just last year's numbers, since a plan that qualified in 2026 doesn't automatically qualify again if your employer didn't raise the deductible. If it still qualifies, update your payroll election for the new plan year to capture the full $4,500 or $9,000 limit if your budget allows it, since payroll contributions are the only way to also avoid the FICA tax shown above. If you're weighing an HSA against a Flexible Spending Account for the first time, our HSA vs. FSA comparison covers the structural differences, and our breakdown of the HSA triple tax advantage covers why leaving the balance invested instead of spending it down can outperform even a 401(k) match dollar for dollar in some cases.
What Are the Real Risks and Trade-Offs?
- A higher contribution limit doesn't help you if your plan stops qualifying. The HDHP deductible and out-of-pocket floors rose too, so check your actual 2027 plan documents, not just the headline HSA number.
- The catch-up contribution is losing real value every year. It's been frozen at $1,000 since 2009 with no inflation indexing, while the base limits keep rising around it.
- Invested HSA balances carry real market risk. Cash sitting in the account is typically FDIC-insured through the custodian bank, but once you invest it in funds, it's exposed to the same volatility as any other brokerage account, with no guarantee against loss.
- Non-medical withdrawals before 65 cost you twice. They're taxed as ordinary income and hit with a 20% penalty, a steeper penalty than a traditional IRA's early withdrawal rules.
- Losing HDHP coverage mid-year gets messy. If you switch to a non-HDHP plan partway through the year, your contribution limit gets prorated, and over-contributing past that prorated amount triggers excess-contribution penalties.
