Can I even open an HSA
making $14/hour?
Yes. There is no income minimum. The only requirement is a high-deductible health plan — which is often the cheapest option offered by gig platforms and warehouse employers.

What happens to the money
I don't spend?
It stays yours. It rolls over. It compounds. Unlike an FSA, your HSA balance invests in the market — the same S&P 500 your employer's 401(k) uses.

Your FSA disappears December 31st. Your HSA compounds for decades. At 65, it converts to a regular retirement account — no strings attached.
Is this just another thing
