# FSA vs HSA: Which Health Account Wins? > HSAs roll over and travel with you; FSAs expire with your job. Compare eligibility, 2026 limits, and which fits your health plan. Canonical: https://christianbrinkleync.com/guides/fsa-vs-hsa-which-is-better ## Quick answer An HSA pairs with a high-deductible health plan, rolls over every year, and follows you between jobs. An FSA works with most plans but is tied to your employer and mostly use-it-or-lose-it. The HSA also carries the triple tax advantage the FSA cannot match. ## Eligibility and ownership You need a qualifying high-deductible health plan to open or fund an HSA. An FSA only needs an employer that offers one, and it works with most health plans. The HSA is your account forever, even after you leave the job. The FSA ends with the job, though a grace period can give you a little extra time. ## Contribution limits for 2026 HSA caps for 2026 are $4,400 self-only and $8,750 family, plus a $1,000 catch-up at 55 and older. The health FSA limit for 2026 is $3,400 per employee from salary reductions. FSA limits apply per employee, so two working spouses can each have one. Both limits adjust yearly for inflation. ## Use-it-or-lose-it vs rollover HSA balances roll over in full every year with no deadline. FSA money generally expires at plan year-end under use-it-or-lose-it. Employers may allow up to $680 in carryover or a grace period of two and a half months. They cannot offer both, so check your plan documents. ## Medicare enrollment ends HSA contributions The month you enroll in Medicare, including premium-free Part A, your HSA eligibility stops. You keep the account and can spend what's in it, but new contributions become excess contributions with a 6% penalty for each year they stay in. The trap: if you sign up for Medicare after 65, Part A backdates up to six months, which can retroactively disqualify contributions you already made. People working past 65 often stop HSA contributions six months before filing for Medicare or Social Security. ## The dependent care FSA is a different animal Separate from the health FSA, the dependent care FSA pays for childcare or adult dependent care so you can work. For 2026 the limit jumps to $7,500 ($3,750 married filing separately), the first increase since 1986. It covers kids under 13, daycare, preschool, and day camps, but not overnight camps. Unlike the health FSA, there's no carryover at all, though some plans offer a short grace period. And it has nothing to do with your health plan choice. ## Your HSA can double as a retirement account After 65, the 20% penalty on non-medical HSA withdrawals disappears. Withdrawals for anything other than medical expenses are taxed as income, like a traditional IRA, but there's no penalty and no required withdrawals ever. That's why some people pay medical bills out of pocket, save the receipts, and let the HSA compound for decades. The IRS lets you reimburse yourself years later as long as the expense happened after the HSA was opened. ## FSA vs HSA head to head | Topic | How they compare | | --- | --- | | Needs a high-deductible plan | HSA: Yes | FSA: No | | 2026 contribution cap | HSA: $4,400 self / $8,750 family | FSA: $3,400 per employee | | Unused money | HSA: Rolls over fully | FSA: Use it or lose it, mostly | ## Checklist - [ ] Check whether your health plan is an HSA-eligible HDHP. - [ ] If you have an FSA, learn your plan's carryover or grace period. - [ ] Never hold a general-purpose FSA and an HSA at the same time. - [ ] Spend FSA money before the deadline or forfeit it. ## Frequently asked questions ### Can I have an HSA and an FSA at the same time? A general-purpose FSA disqualifies you from HSA contributions. A limited-purpose FSA for dental and vision is allowed alongside an HSA. Confirm your FSA type before funding both. ### Which works better for predictable medical costs? An FSA can fit well when you know your expenses for the year. The full annual election is available on day one, before you finish contributing. An HSA is stronger for building a long-term medical fund. ### I'm 66, still working, and on my employer's plan. Can I keep funding my HSA? Only if you're not enrolled in Medicare. Once Part A starts, contributions have to stop. If you delayed Medicare past 65, remember Part A backdates up to six months, so stop contributing at least six months before you apply. ### What are the 2026 HDHP minimums to qualify for an HSA? The plan must have a deductible of at least $1,700 self-only or $3,400 family, and out-of-pocket maximums no higher than $8,500 self-only or $17,000 family. If your plan's numbers don't clear both bars, it's not HSA-eligible no matter what HR calls it. ## Sources - [IRS Publication 969: Health Savings Accounts](https://www.irs.gov/publications/p969) - [IRS: Tax Topics](https://www.irs.gov/taxtopics) - [IRS: Publication 503, Child and Dependent Care Expenses](https://www.irs.gov/publications/p503) - [IRS: Revenue Procedure 2025-19, 2026 HSA and HDHP figures](https://www.irs.gov/pub/irs-drop/rp-25-19.pdf) ## Related - [HSA explained, plainly](https://christianbrinkleync.com/wealth/hsa-explained) - [What happens to your HSA or FSA after leaving a job](https://christianbrinkleync.com/guides/hsa-fsa-after-leaving-job) - [HSA triple tax advantage](https://christianbrinkleync.com/guides/hsa-triple-tax-advantage) --- Educational content only, not financial or tax advice.
