Open enrollment season is right around the corner, and the IRS has already given us the headline number for next year: the 2027 HSA contribution limit is rising to $4,500 for self-only coverage and $9,000 for family coverage, up from $4,400 and $8,750 in 2026. If you have, or are considering, a high-deductible health plan, now is the time to start planning around it, well before your employer’s enrollment window opens.
The New 2027 Numbers
The IRS released the 2027 Health Savings Account and high-deductible health plan limits in late May 2026. Here’s how they compare:
- Self-only HSA contribution limit: $4,500 for 2027, up from $4,400 in 2026
- Family HSA contribution limit: $9,000 for 2027, up from $8,750 in 2026
- Catch-up contribution (age 55+): An additional $1,000, unchanged, as it isn’t inflation-indexed
The IRS releases HSA limits earlier than most other benefit figures specifically so employers and payroll providers can build the new numbers into fall open enrollment materials and payroll elections for the coming plan year.
FSA limits for 2027 haven’t been officially released yet; the IRS typically publishes those in a separate revenue procedure in October or November. Early industry projections point to a modest increase from 2026’s $3,400 limit, with a $700 carryover allowance, but treat that as a preview rather than a confirmed number until the IRS publishes it.
Why HSAs Are Worth Paying Attention To
A Health Savings Account is one of the few accounts in the tax code with triple tax benefits: contributions are tax-deductible (or pre-tax through payroll), growth inside the account isn’t taxed, and withdrawals for qualified medical expenses come out tax-free. Unlike an FSA, HSA balances roll over year to year with no use-it-or-lose-it deadline, and once you leave a high-deductible health plan, the account is still yours to spend or invest.
That combination is why many financial planners treat a fully funded HSA as a retirement planning tool as much as a healthcare one. Some HSA providers let you invest balances above a certain threshold in mutual funds, similar to a 401(k), letting the account grow for years before you tap it for medical costs in retirement.
What to Do Before Open Enrollment
1. Confirm you’re actually eligible
You can only contribute to an HSA if you’re enrolled in an IRS-qualifying high-deductible health plan (HDHP) and don’t have other disqualifying coverage, such as being claimed as a dependent or being enrolled in Medicare. Check your plan’s deductible and out-of-pocket maximum against current IRS HDHP thresholds before assuming you qualify.
2. Decide whether to max out your contribution
If your budget allows it, contributing up to the full $4,500 or $9,000 limit captures the largest possible tax deduction and gives your balance more room to grow. If cash flow is tight, prioritize contributing at least enough to cover your plan’s deductible, so you’re not caught short if you have a medical expense early in the year.
3. Compare HSA vs. FSA if your employer offers both
You generally can’t contribute to both a standard FSA and an HSA in the same year. If your employer offers a choice, weigh the HSA’s rollover and investment features against an FSA’s typically lower deductible plan pairing. Families with predictable, moderate medical expenses sometimes still prefer an FSA’s simplicity; those who rarely hit their deductible often come out ahead with an HSA’s flexibility.
4. Use the “1,000 catch-up” if you’re 55 or older
The extra $1,000 catch-up contribution for savers 55 and up isn’t inflation-adjusted, so it’s easy to forget it exists. If you’re eligible, factor it into your open enrollment elections.
5. Revisit your broader savings plan
An HSA works best as part of a coordinated plan alongside your emergency fund and other savings accounts, not as a replacement for them. If a medical expense hits before your HSA balance can cover it, you’ll want liquid savings to bridge the gap without going into debt.
What Happens to Unused HSA Funds
One of the biggest differences between an HSA and an FSA is what happens to money you don’t spend by year-end. FSA balances are generally subject to a use-it-or-lose-it rule, with only a limited carryover allowed. HSA balances have no such deadline: whatever you don’t spend simply stays in the account, continuing to grow tax-free, and remains available for qualified medical expenses at any point in the future, including well into retirement. That makes overfunding an HSA a far smaller risk than overfunding an FSA, and it’s part of why some planners encourage eligible savers to contribute up to the annual limit even if they don’t expect major medical expenses in the near term.
A Note on Timing
Most employer open enrollment periods run through October and November for coverage that begins January 1. Because HSA elections are typically set through payroll, the amount you choose during open enrollment locks in your contribution schedule for the year, though most plans let you adjust it later if your circumstances change. Setting your target contribution now, based on the new 2027 limits, means you won’t be scrambling to recalculate numbers when your enrollment window actually opens.
Bottom Line
The IRS has already told us where HSA limits are headed for 2027: $4,500 for individual coverage and $9,000 for family coverage. Use the months before open enrollment to check your eligibility, decide on a contribution target, and compare your HSA against any FSA option your employer offers, so you’re ready to elect the right number the moment enrollment opens.
