The IRS has officially released the 2027 cost-of-living adjustments for Health Savings Accounts (HSAs) via Revenue Procedure 2026-24, and the numbers are moving in the right direction. Contribution limits are up. Deductible thresholds are up. And for employers who offer — or are considering — HSA-eligible health plans, the timing to act on this information is now.
Whether you're an HR leader benchmarking your 2027 benefits strategy, a broker advising employer clients on plan design, or an employer looking for ways to deliver more value without increasing costs, here's a complete breakdown of what changed, why it matters, and how to make the most of it.
What the IRS confirmed: the 2027 HSA limits in full
Released on May 29, 2026, Rev. Proc. 2026-24 provides the inflation-adjusted contribution and coverage thresholds for HSAs under Code Section 223(g), effective January 1, 2027.
Self-only coverage — what changed:
- The annual minimum deductible increases from $1,700 in 2026 to $1,750 in 2027
- The maximum out-of-pocket rises from $8,500 to $8,700
- The maximum HSA contribution goes from $4,400 to $4,500 — a $100 increase
Family coverage — what changed:
- The annual minimum deductible increases from $3,400 in 2026 to $3,500 in 2027
- The maximum out-of-pocket rises from $17,000 to $17,400
- The maximum HSA contribution goes from $8,750 to $9,000 — a $250 increase and the first time the family limit has crossed $9,000
Catch-up contributions (age 55 and older):
- The catch-up limit remains $1,000 for 2027, unchanged from 2026
- This limit is set by statute, not adjusted for inflation, and has held flat since 2009
- Eligible employees can contribute this amount on top of the standard annual limit
The increases are modest by design — these are inflation adjustments, not policy changes. But as context below makes clear, they land at a moment when HSAs are growing faster than at any point in their history.
Why this update matters more than a routine number change
Annual IRS limit adjustments are easy to file away as compliance housekeeping. But in 2027, the context surrounding these numbers makes them worth closer attention.
HSA adoption is at an all-time high. According to Devenir's 2025 Year-End HSA Research Report, HSAs closed out 2025 holding nearly $174 billion in assets across 41.7 million accounts — a 19% year-over-year increase in total assets and 6% growth in the number of accounts. Devenir projects the HSA market will surpass 49 million accounts and $234 billion in total assets by the end of 2028. These are not niche numbers — HSAs have become a central pillar of how Americans plan for healthcare costs, and the employers who support strong HSA programs are well-positioned as that momentum continues.
Employees are treating HSAs as long-term savings vehicles, not just spending accounts. HSA investment assets reached nearly $85 billion at year-end 2025 — up 33% from the prior year (Devenir). About 4.2 million accounts, or roughly 10% of all HSAs, held invested dollars at year-end. Employees who invest their HSA balances hold an average of $24,252 — nearly ten times the average balance of a funded account without investments. Higher contribution limits in 2027 give more employees the ability to build those balances over time.
Healthcare cost anxiety is driving demand. A 2026 survey from D.A. Davidson found that 78% of Americans reported fears about the impact of rising healthcare costs in retirement. Every dollar of additional contribution room the IRS grants is another dollar employees can move into the most tax-efficient savings vehicle available to them.
HSA eligibility just got broader. The One Big Beautiful Bill Act, signed on July 4, 2025, added new provisions allowing direct primary care service arrangements (DPCSAs) to be paired with HSAs without disqualifying participants from contributing. This is the broadest expansion of HSA eligibility in recent memory — and it makes the 2027 limits even more relevant as more plan designs become HSA-compatible.
The triple tax advantage: still the most powerful tool in the benefits toolkit
Before getting into employer strategy, it's worth grounding the conversation in what makes HSAs structurally different from every other benefits account. HSAs carry a triple tax advantage that no other savings vehicle in the U.S. tax code can match:
- Contributions are tax-free — employee contributions through payroll are pre-tax; employer contributions are excluded from the employee's gross income and exempt from FICA taxes
- Growth is tax-free — interest and investment earnings inside an HSA accumulate without federal income tax, indefinitely
- Withdrawals for qualified medical expenses are tax-free — at any age, for any IRS-qualified expense
No other account type — not a 401(k), not an FSA, not an IRA — provides all three benefits simultaneously. For employers, this is a critical talking point when communicating benefits value to employees who may not fully appreciate what they have access to. For brokers, it's one of the clearest differentiators when helping employer clients compare plan designs and total compensation value.
What employers and brokers should do with this right now
The 2027 limits are effective January 1, 2027 — which means plan year decisions and open enrollment communications are already on the horizon. Here's where to focus:
Review HDHP plan design for 2027 compliance
- Confirm that your 2027 HDHP deductibles meet the new minimums — $1,750 for self-only coverage, $3,500 for family coverage
- Confirm that out-of-pocket maximums don't exceed the new IRS caps — $8,700 for self-only, $17,400 for family
- A plan that fell within the thresholds in 2026 may need adjustment to remain HSA-eligible in 2027 — this is not automatic
- Plans that don't meet these thresholds disqualify participants from HSA contributions entirely, even if participants believe they are enrolled in an eligible plan
Update employee contribution elections
- Prompt employees to review and update their 2027 HSA contribution elections before the plan year begins
- Highlight the family limit crossing $9,000 for the first time in open enrollment materials — it's a concrete, communicable milestone
- Remind employees aged 55 and older that their $1,000 catch-up contribution remains available on top of the standard limit
- Employees who don't actively update their elections will often carry forward the same amount as the prior year, leaving the new contribution room unused
Revisit employer contribution strategy
- Employer contributions to employee HSAs are tax-deductible for the employer and excluded from the employee's gross income
- Both employee and employer contributions count toward the annual IRS limit — employers who contribute need to ensure combined amounts stay within the 2027 cap
- Employers who don't currently offer contributions should weigh whether a modest employer HSA seed — even $250 to $500 — meaningfully improves benefits attractiveness without major cost impact
Communicate early and with specifics
- 61% of all HSA accounts are employer-affiliated (Devenir) — meaning employers are the primary channel through which most employees engage with and understand their HSAs
- Open enrollment materials that name the actual limits, explain the tax advantages in plain terms, and show what maximum contribution looks like in annual tax savings tend to drive meaningfully higher participation rates
- Employees who understand their HSA are more likely to fund it, invest it, and retain it — all of which benefits long-term workforce financial wellness
HSA compliance: the stakes don't change when the limits do
Higher limits bring the same compliance obligations. These are the areas where employers most commonly run into issues:
- Eligibility verification — employees must be enrolled in a qualifying HDHP and cannot simultaneously hold Medicare coverage, a general-purpose health FSA, or be claimed as a dependent on another person's tax return
- Contribution limit monitoring — combined employee and employer contributions cannot exceed the annual IRS limits; mid-year enrollment changes, new hires, and terminations require prorated limit calculations that must be tracked carefully
- W-2 reporting — employer HSA contributions must be reported on the employee's W-2 in Box 12, Code W; errors here create downstream tax issues for employees
- HDHP plan design review — deductibles and out-of-pocket maximums must fall within IRS-defined HDHP thresholds each plan year; these thresholds change annually and must be confirmed with carriers before the plan year begins
- Cafeteria plan alignment — employee HSA contributions made through payroll deduction must flow through a Section 125 cafeteria plan to receive pre-tax treatment; employers without a compliant cafeteria plan in place cannot offer this benefit properly
Errors in any of these areas can disqualify employees from contributing to their HSA — or strip the tax benefits they've already received — creating both a participant relations problem and a compliance exposure for the employer.
