Plain-English why
Copyable takeaway
What this means
No waffle. Just the number and how it was worked out.
Formula used
Tax saving = annual contribution × marginal tax rate. HSA vs FSA suitability scored by HDHP eligibility, carryover need, and spend predictability.
Worked example
A single person on an HDHP earning $75,000 with $2,000 expected medical spend contributes the $4,150 HSA max: tax saving of approximately $1,000 and unspent funds carry over indefinitely.
Common questions
What is the difference between an HSA and FSA?
An HSA (Health Savings Account) requires a High Deductible Health Plan but funds roll over year to year and can grow tax-free as investments. An FSA (Flexible Spending Account) works with any plan but is largely use-it-or-lose-it each year.
Can I have both an HSA and FSA?
Generally not simultaneously — having an HSA means you cannot contribute to a standard FSA. A Limited Purpose FSA for dental and vision only is compatible with an HSA.
