Frequently asked questions
- Do employer contributions count toward my HSA limit?
- Yes. The IRS limit is a combined cap, so anything your employer deposits reduces what you can add yourself. This calculator subtracts both to show your real remaining room.
- How much extra can I contribute if I'm 55 or older?
- An additional $1,000 per year as a catch-up contribution, on top of the standard limit. If both spouses are 55+, each needs their own HSA to claim the full catch-up.
- What happens if I over-contribute to my HSA?
- Excess contributions are generally subject to a 6% excise tax each year they remain in the account. Withdraw the excess (and any earnings on it) before your tax deadline to avoid the penalty.
