Can I have both HSA and FSA?

Generally not at the same time. A limited-purpose FSA (dental and vision only) can co-exist with HSA. A general-purpose FSA disqualifies HSA contributions.

Do HSA contributions reduce FICA?

Pre-tax HSA contributions through payroll (cafeteria plan) reduce FICA wages. After-tax HSA contributions you make outside payroll do not.

What happens to my FSA if I leave my job?

Unspent FSA funds typically forfeit, with limited COBRA-style continuation rights in some plans. Use it before you leave.

PayslipIQ, Understand Your Paycheck With Confidence

HSA vs FSA

Both pay for medical expenses with pre-tax dollars. They behave very differently. HSA is yours for life, FSA is use-it-or-lose-it.

PayslipIQ provides educational information and estimated calculations only. It does not provide tax, legal, financial, accounting, employment, benefits, or payroll advice. PayslipIQ is not a CPA firm, law firm, financial advisor, payroll provider, or tax authority. Always verify your paycheck, deductions, withholdings, and tax position with your employer's payroll department, a qualified CPA, the IRS, your state tax authority, or another appropriately qualified professional. Calculations are estimates; your actual paycheck may differ based on factors specific to your employer, location, benefits elections, and personal tax situation.

Eligibility

HSA requires a High Deductible Health Plan (HDHP). FSA is offered with most employer plans, no HDHP required.

Annual limits

HSA limits are higher than FSA and rise faster. The IRS publishes both annually. Verify at irs.gov.

Rollover

HSA rolls over fully year to year. Forever. You take it with you when you change employers. FSA traditionally is use-it-or-lose-it, with a small carryover or grace period if your plan allows.

Investment

HSA can be invested once you hit a balance threshold. Long-term investment growth is tax-free for qualified medical expenses. FSA is not invested.

Tax treatment

Both are pre-tax for federal income tax, FICA, and most state taxes. Both reduce taxable wages.

Ownership

HSA is yours, in your name, at a custodian (bank or broker) you choose (within plan rules). FSA is owned by the employer's plan, you forfeit unspent funds when you leave.

Triple tax advantage of HSA

1. Contributions reduce taxable wages. 2. Investment growth is tax-deferred. 3. Withdrawals for qualified medical expenses are tax-free. No other account has all three.

FSA strengths

No HDHP requirement. Often lower-deductible plans pair with FSA. Useful if you have predictable medical or dependent-care expenses each year.
