Switching Jobs? What Happens to Your FSA and HSA Money

Short answer: if you leave your job, your FSA money usually stays behind — most plans end on your last day of work, and unspent funds go back to your employer. Your HSA is different: it belongs to you and moves with you, no matter where you work.

Job changes are stressful enough without discovering that a chunk of your paycheck quietly disappeared with your old badge. If you have money sitting in a flexible spending account (FSA) or a health savings account (HSA) and a new job on the horizon, a little planning in your final weeks can save you hundreds of dollars. Here's how the two accounts behave when you switch jobs, what deadlines actually matter, and how to put a use-it-or-lose-it balance to work before it's gone.

What happens to my FSA when I leave my job?

In most cases, your FSA participation ends on your last day of employment, and any money you haven't spent by then is forfeited to your employer. That's because an FSA is technically owned by your employer, not you — the IRS explains the structure in Publication 969. It doesn't matter that the money came out of your paychecks; once you separate, the window to rack up new eligible expenses generally closes.

Two details soften this, and they're worth checking with your HR or benefits administrator:

• The run-out period. Most plans give you a stretch of time after termination — often 90 days — to submit claims for eligible expenses you incurred while you were still employed. This is a filing deadline, not extra spending time. Purchases made after your last day usually don't count.
• COBRA continuation. Some people can temporarily continue their health FSA through COBRA, typically when the amount already contributed exceeds what's been reimbursed. You'd keep contributing with after-tax dollars, which only makes sense in specific situations — ask your administrator to run the numbers.

What happens to my HSA when I change jobs?

Your HSA goes with you — all of it. Unlike an FSA, an HSA is an account you own outright, the same way you own a personal bank account. Your contributions, your employer's contributions, and any investment growth stay yours after you leave, and the balance never expires. You can keep spending it on qualified medical expenses between jobs, at your new job, or in retirement.

One caveat: to keep adding new money to an HSA, you need to be enrolled in an HSA-qualified high-deductible health plan. If your new employer's insurance isn't HSA-eligible, your existing balance still works fine for eligible purchases — you just can't contribute more until you're back on a qualifying plan.

Should I spend my FSA balance before my last day?

If your plan follows the standard rules, yes — spending your remaining FSA balance on eligible expenses before you leave is usually the smartest move. Otherwise that pre-tax money simply goes back to your employer. A few sensible places it can go:

• Stocking up on prescriptions, contact lenses, or first-aid supplies
• Scheduling that dental cleaning or eye exam you've been putting off
• Durable items you'll use for years — including FSA/HSA-eligible red light therapy devices

That last category is where a leftover balance can quietly become a long-term win. A compact panel like the FX300 red light therapy panel ($199.99) delivers 660nm red and 850nm near-infrared light for targeted use on joints and muscles, and the Red Light Therapy Belt ($119.99) wraps around the back, knee, waist, or shoulder — a practical fit for smaller remaining balances. Researchers have studied this kind of light therapy (photobiomodulation) for decades as a drug-free adjunct for easing musculoskeletal discomfort; a widely cited review by Cotler and colleagues summarizes the evidence on pain and inflammation.

Can I still submit FSA claims after I've left?

Yes — for expenses you incurred while you were still employed, as long as you file within your plan's run-out period. Keep your receipts and itemized statements, and submit them promptly rather than waiting until the deadline. If a claim is for a service, what matters is the date of service, not the date you were billed or paid.

What should I do with my HSA after switching jobs?

You have a few good options, and none of them involve losing money. You can leave the HSA where it is, transfer it to a provider with lower fees or better investment options, or roll it into a new HSA your next employer offers. Whatever you choose, the balance remains yours to spend on qualified medical expenses — from doctor visits to eligible wellness devices — whenever you need it. Details on qualified expenses live in IRS Publication 969.

Frequently asked questions

Do I lose my FSA money the day I quit?

Generally, you can no longer incur new eligible expenses after your last day of employment, and unspent funds are forfeited. You typically still have a run-out period to file claims for expenses from before you left.

Does my HSA balance expire if I'm unemployed?

No. HSA funds never expire and remain yours regardless of employment status. You can spend them on qualified medical expenses at any time — you just can't make new contributions unless you're enrolled in an HSA-qualified high-deductible health plan.

Can I use my FSA card during my notice period?

Usually yes. If you're still employed, you're typically still covered by the FSA, so eligible purchases made before your last day generally count. Confirm your exact coverage end date with HR, since some plans end coverage on the termination date and others at the end of that month.

Is red light therapy FSA/HSA eligible?

Yes — red light therapy devices like the ones AWA sells are FSA/HSA eligible, and you can pay with your benefits card at checkout. Our FSA/HSA-eligible collection shows everything that qualifies.

What happens to employer HSA contributions when I leave?

Once deposited, employer contributions are yours and leave with you. There's no vesting schedule or clawback on money already in the account.

Can I transfer FSA money into an HSA?

No. FSA and HSA funds can't be merged, and an unused FSA balance can't be rolled into an HSA. That's why spending down an FSA before a job change matters so much.

The bottom line

Treat your FSA like a gift card that expires on your last day, and your HSA like a bank account that follows you for life. Check your FSA balance as soon as you know you're leaving, spend it on things you'll actually use, and keep receipts for the run-out period. Your future self — and your joints — will thank you.
