HSA vs. FSA: Which Account Actually Saves Midwest Families More?

Both an HSA and an FSA let you pay for medical costs with pre-tax dollars. The rules around who can open one, what happens to unused money, and how much you can put in are very different, and that difference is worth real money.

The short version

• HSA: requires a qualified high deductible health plan, money rolls over forever, and the account is yours to keep.
• FSA: offered through an employer, mostly use it or lose it, and it stays with the job.

Who can open an HSA

You need to be enrolled in an HSA qualified high deductible health plan, have no other disqualifying coverage, and not be enrolled in Medicare or claimed as a dependent. Self employed and 1099 workers can open one on their own, which is why I bring it up in almost every self employed plan review.

• Contributions are tax deductible even if you do not itemize
• Growth and qualified withdrawals are tax free
• Unused funds roll over year after year and can be invested
• After 65 you can withdraw for any reason, paying only ordinary income tax

How an FSA works

An FSA is set up by an employer. You elect an amount at open enrollment, it comes out of your paycheck pre-tax, and the full election is available on day one of the plan year.

• No high deductible plan required
• Front loaded access to the full election amount
• Balances generally do not carry over, though some plans allow a small carryover or a short grace period
• The account does not follow you if you leave the job

Side by side

• Eligibility: HSA needs a qualified high deductible plan, FSA needs an employer offering one
• Rollover: HSA carries over fully, FSA usually does not
• Portability: HSA is yours, FSA is not
• Investing: HSA funds can be invested, FSA funds cannot
• Access to funds: FSA gives you the full election up front, HSA only holds what you have contributed so far

Picking the right one

If you are relatively healthy, can handle a higher deductible, and want a long term tax advantaged account, the HSA is hard to beat. If you have predictable recurring costs like ongoing prescriptions, braces, or planned procedures, an FSA can be the better fit because you get the whole amount immediately.

A note for people approaching 65: once you enroll in any part of Medicare you can no longer contribute to an HSA, though you can still spend what is already in it. If you plan to keep working past 65, we should map the timing out before you enroll.

Check the plan before you assume

Not every high deductible plan is HSA qualified, and contribution limits change each year. Before you commit at open enrollment, send me your plan documents and I will confirm eligibility, walk through the numbers with your expected costs, and tell you plainly which account leaves more money in your pocket.
