HSA vs FSA: Which Account Fits?

Ownership and rollover

HSAs are yours and roll over forever if you stay eligible to contribute. FSAs are usually employer plans with use-it-or-lose-it rules (with limited exceptions).

Only HSA-eligible HDHPs unlock HSA contributions.

Practical choice

Choose HSA + HDHP if you can fund the deductible and want long-term tax-free growth. Choose FSA when your employer offers rich contributions and you have predictable near-term expenses.

Some employers offer limited-purpose FSAs alongside HSAs for dental/vision.

Frequently asked questions

Can I have both?

Sometimes a limited-purpose FSA with an HSA; a general-purpose FSA usually blocks HSA contributions.

What happens to FSA money at year end?

Often forfeited unless your plan offers a grace period or small rollover.
