Health Savings Account (HSA) Explained | CafeHealth
What is Health Savings Account (HSA)?
Here's the honest answer: as of right now, the IRS has not yet published official HSA contribution limits for 2027. The IRS typically announces the next year's limits in the spring of the prior year, so 2027 numbers will likely show up sometime around May 2026. What you can do today is look at the confirmed 2025 and 2026 limits, understand the pattern the IRS uses to set them, and plan your 2027 elections with a realistic range in mind instead of a guess pulled out of thin air.
This matters because Health Savings Accounts (HSAs) are one of the few accounts in the tax code that give you a triple tax break: your contributions go in tax-free, your money grows tax-free, and withdrawals for qualified medical expenses come out tax-free too. But you can only use one if you're enrolled in a High-Deductible Health Plan (HDHP), and the IRS sets specific dollar limits every year for both your HSA contributions and the HDHP itself. Let's walk through what's confirmed, what's likely coming, and what you should be doing right now.
What Is an HSA and How Does It Work With an HDHP?
An HSA is a personal savings account you can only open and fund if you're covered by a qualified High-Deductible Health Plan (HDHP). Unlike a Flexible Spending Account (FSA), the money in your HSA is yours permanently. There's no "use it or lose it" deadline, no employer clawback if you leave your job, and no forfeiture at year-end. Whatever you don't spend just keeps growing, year after year, and many HSA providers let you invest the balance once it hits a certain threshold, similar to a 401(k).
You can use HSA funds for a long list of IRS-qualified medical, dental, and vision expenses, per IRS Publication 502. Once you turn 65, you can also withdraw funds for non-medical reasons without the usual 20% penalty, though you'll owe regular income tax on that portion, similar to a traditional IRA.
Here's the catch: you can't just decide to open an HSA on your own. You have to be enrolled in an HDHP that meets IRS minimum deductible and maximum out-of-pocket thresholds, and you can't be covered by another disqualifying health plan, like a general-purpose FSA, at the same time. That's why HSA eligibility and HDHP plan design are joined at the hip, and why employers need to get the plan setup right before open enrollment, not after.
What Are the 2027 IRS HSA Contribution Limits?
This is the part where we have to be straight with you: the IRS has not released official 2027 HSA contribution limits as of this writing. These numbers come out via an annual Revenue Procedure, usually published in May of the preceding year, so the 2027 figures should land around mid-2026. Anyone telling you an exact 2027 number right now is guessing or hasn't checked the calendar.
What we do know, straight from the IRS:
●2025 limits (confirmed, IRS Rev. Proc. 2024-25): $4,300 for self-only coverage, $8,550 for family coverage.
●2026 limits (confirmed, IRS Rev. Proc. 2025-19): $4,400 for self-only coverage, $8,750 for family coverage.
Look at the pattern: self-only went up $100 and family went up $200 from 2025 to 2026. That's roughly a 2.3% increase, driven by the chained CPI inflation formula Congress wrote into the tax code for HSA limits. If inflation stays in that same range, a reasonable working estimate for 2027 self-only coverage lands somewhere near $4,500 to $4,600, and family coverage somewhere near $8,900 to $9,050. Treat that as a planning range, not a fact, until the IRS publishes the real number.
Our advice: don't lock in your 2027 payroll deduction elections based on a guessed number. Use the confirmed 2026 limit as your floor, check IRS.gov or your CafeHealth account rep in spring 2026 for the official figure, and adjust before your open enrollment window closes.
How Do Catch-Up Contributions Work If I'm 55 or Older?
If you're 55 or older, you get to add extra money on top of the standard limit. This one's easy because it doesn't move with inflation, it's a flat amount fixed directly into the tax code under IRC Section 223(b)(3).
●Catch-up contribution amount: $1,000 per year, confirmed for 2025, 2026, and expected to stay at $1,000 for 2027 since Congress hasn't adjusted this figure since it was introduced in 2009 (per IRS Publication 969).
●You have to turn 55 by December 31 of the tax year to qualify, not by the time you file your return.
●If you're married and both spouses are 55+, each spouse needs their own HSA to claim their own $1,000 catch-up. You can't dump both catch-up amounts into one account.
So if the 2027 family limit does land around $8,900 to $9,050 as we estimated above, a married couple where both spouses are 55+ could realistically be looking at combined contribution room in the $10,900 to $11,050 range, split across two accounts. That's real money to shelter from taxes every year, which is why this detail trips up a lot of near-retirement employees who forget to open that second account.
What HDHP Deductible and Out-of-Pocket Limits Qualify for an HSA in 2027?
Minimum Deductible Requirements
To even be HSA-eligible, your health plan has to meet a minimum annual deductible set by the IRS. Confirmed figures:
●2025: $1,650 self-only, $3,300 family (IRS Rev. Proc. 2024-25)
●2026: $1,700 self-only, $3,400 family (IRS Rev. Proc. 2025-19)
These minimums move slowly, sometimes staying flat for a year or two, so 2027 will likely sit close to the 2026 numbers, possibly identical or up by $50 to $100.
Maximum Out-of-Pocket Limits
The IRS also caps how much you can be required to pay out-of-pocket, including deductibles, copays, and coinsurance, before the plan has to cover 100%. Confirmed figures:
●2025: $8,300 self-only, $16,600 family
●2026: $8,500 self-only, $17,000 family
Based on that trend, a reasonable 2027 estimate would put self-only out-of-pocket maximums around $8,600 to $8,700, and family around $17,200 to $17,400. Again, these are planning estimates, not confirmed figures, and your employer's actual plan can set lower out-of-pocket maximums than the IRS ceiling, they just can't go higher.
If you're an employer redesigning your plan for 2027, get your plan documents to your broker or TPA early. A plan that misses these thresholds by even a few dollars can disqualify every employee's HSA contributions for the year, which creates a compliance mess nobody wants to untangle in Q1.
What Are the Rules When My Employer Contributes to My HSA?
A lot of employers sweeten the deal by putting money into employees' HSAs directly, sometimes as a flat annual deposit, sometimes as a match tied to employee contributions. That employer money still counts toward the same annual IRS limit, so if your employer puts in $1,000 and the limit is $4,400, you personally can only add up to $3,400 more.
The Comparability Rule
If an employer contributes to HSAs outside of a Section 125 cafeteria plan, IRC Section 4980G requires those contributions to be comparable across all employees in the same coverage tier. In plain terms: you generally can't give the CEO $2,000 and the warehouse staff $500 for the same coverage level. Get this wrong and the employer owes a 35% excise tax on the total HSA contributions made that year, per IRS guidance on Section 4980G. That's a steep penalty for what's usually a payroll setup mistake.
Cafeteria Plan Exception
If contributions run through a Section 125 cafeteria plan instead, comparability rules don't apply, but the contributions have to meet Section 125 nondiscrimination testing instead. Either way, there's a compliance layer here that payroll and HR teams often miss, especially when they're juggling HDHP renewal, open enrollment, and W-2 reporting all at once.
A few payroll basics worth double-checking every year:
1.Employer and employee HSA contributions both need to show up correctly on Form W-2, Box 12, Code W.
2.Employee pre-tax payroll contributions need a signed Section 125 cafeteria plan election on file.
3.Mid-year HDHP enrollment changes require prorated contribution limit recalculations, not a flat annual number.

Quick HSA Questions People Actually Ask
What is the HSA contribution limit for 2027?
Honestly, the IRS hasn't published it yet. They usually announce next year's limits around May of the year before, so 2027 numbers should come out around spring 2026. Based on the jump from 2025 to 2026, a reasonable estimate is somewhere around $4,500 to $4,600 for self-only coverage and $8,900 to $9,050 for family coverage, but treat that as a planning guess, not a locked-in number.
How much extra can I contribute to my HSA if I'm 55 or older?
You get an extra $1,000 a year, called a catch-up contribution. This amount is fixed by law and hasn't changed since 2009, so it should stay at $1,000 for 2027 too. Just remember, if you're married and both spouses are 55+, each of you needs your own separate HSA to claim your own $1,000, you can't combine it into one account.
Can my employer put money into my HSA too?
Yep, and a lot of employers do, either as a flat deposit or a match. That money counts toward your total annual limit though, so if your employer contributes $1,000 and the limit is $4,400, you can only add $3,400 more yourself. Employers also have to follow comparability rules under IRC Section 4980G so they're not favoring certain employees over others, unless the contributions run through a cafeteria plan, which follows different nondiscrimination rules instead.
What deductible does my health plan need to have to qualify for an HSA?
For 2026, the confirmed minimum deductible is $1,700 for self-only coverage and $3,400 for family coverage. Your plan's deductible has to meet or exceed those numbers to count as an HSA-eligible HDHP. The 2027 minimums will likely land close to those same figures, but check with your HR team or your plan documents once the IRS confirms them.
What happens to my HSA balance if I change jobs or leave my employer?
Nothing happens to it, it's yours. Unlike an FSA, your HSA isn't tied to your employer at all. You keep the account, keep the balance, and keep using it for qualified medical expenses whether you're employed, unemployed, or retired. You can also roll it into a new HSA provider if you want lower fees or better investment options, similar to an IRA rollover.
Do I lose my HSA money at the end of the year if I don't spend it?
No, and this is the biggest thing people confuse with FSAs. HSA funds roll over indefinitely, there's no year-end deadline and no forfeiture. Whatever you don't use just stays in the account and keeps growing, which is part of why HSAs work well as a long-term savings tool, not just a spending account.
