The basic rule: use it or lose it
FSA money is a beautiful thing until it isn't. When you quit, you lose access to it.
Whatever you've contributed for the year that you haven't used? Gone. Forfeited. The company keeps it. This is not financial advice. But it is brutal.
That's the FSA game. Pre-tax money is great right up until it's not.
The timing trick before you walk out
If you've contributed more than you've used, buy everything medical you can before your last day. And I mean everything.
New glasses? Get them. Contacts? Stock up. Prescriptions? Fill them. Dental work you've been putting off? Do it now. Hearing aids. Orthotics. FSA covers way more than people think.
The money is already set aside. It's already been taken from your paycheck. Use it.
Grace periods sometimes exist
Some employers give a 2.5-month grace period after you quit. Meaning you can still use the FSA for a couple months after you're gone.
Check your plan. Call HR before you quit. Ask: "If I leave on [date], can I keep using my FSA?"
Some companies give you the grace period. Some don't. You need to know.
COBRA for FSA is usually garbage
You can extend FSA coverage through COBRA. COBRA lets you keep some benefits when you leave, but you pay the full cost (the company was subsidizing it).
For FSA? It's usually not worth it unless you have a specific medical expense you know is coming. The admin costs are high, the money doesn't roll over, and you're basically paying to keep a use-it-or-lose-it account.
Skip COBRA FSA unless you have a real reason.
Don't leave money on the table
Before you quit, do an audit. How much have you used? How much is left? What medical stuff could you realistically buy before your last day?
New computer glasses for eye strain? Fine. Root canal? Sure. Massage therapy? Check if your plan covers it. Noise-canceling earplugs for work? If it's medical grade, it might be covered.
The money is yours. It's already been deducted from your pay. Use it.
Your employer is banking on people not knowing how to use FSA. Don't be one of them.
Get in, use the money, get out.
