Frequently asked questions
- How much does an FSA actually save me?
- You save your contribution times your combined income and payroll tax rate. At a 29.65% combined rate, a $2,400 contribution saves about $711.60, so it costs roughly $1,688 of take-home pay.
- What happens to FSA money I don't spend?
- Most plans follow 'use it or lose it' — unspent funds are forfeited at year-end. Some plans allow a limited carryover or a grace period, so check your plan's rules before electing a large amount.
- Can I have both an FSA and an HSA?
- Not a general-purpose health FSA alongside an HSA — that disqualifies HSA contributions. A 'limited-purpose' FSA (dental and vision only) can be paired with an HSA.
