Frequently Asked Questions

What is the HSA contribution limit for 2025?

For 2025, the HSA contribution limit is $4,300 for self-only coverage and $8,550 for family coverage. Individuals aged 55 or older can make an additional $1,000 catch-up contribution. These limits include both employee and employer contributions combined.

What is the triple tax advantage of an HSA?

HSAs offer a unique triple tax advantage: contributions are tax-deductible (or pre-tax through payroll), the funds grow tax-free through interest and investments, and withdrawals for qualified medical expenses are completely tax-free. If contributed through payroll deduction, you also avoid FICA taxes, making it effectively a quadruple tax benefit.

Can I invest my HSA funds?

Yes, most HSA providers allow you to invest your HSA funds in mutual funds, index funds, and other securities once your balance exceeds a minimum threshold (often $1,000-$2,000). Investment growth is tax-free, making HSAs a powerful long-term savings vehicle. Many financial advisors recommend investing HSA funds and paying current medical expenses out of pocket to maximize tax-free growth.

Who is eligible for an HSA?

To be eligible for an HSA, you must be enrolled in a High Deductible Health Plan (HDHP), have no other non-HDHP health coverage, not be enrolled in Medicare, and not be claimed as a dependent on someone else's tax return. For 2025, an HDHP must have a minimum deductible of $1,650 for self-only or $3,300 for family coverage.
