What Is a Health Savings Account (HSA) and How Does It Work?

A Health Savings Account (HSA) is a powerful financial tool that lets you save tax-free money for eligible medical expenses. If you have a high-deductible health plan (HDHP), an HSA can help reduce your healthcare costs—while also offering triple tax benefits.

Whether you’re trying to prepare for unexpected medical bills or save for healthcare in retirement, an HSA is worth understanding.


🔍 How Does a Health Savings Account Work?

An HSA functions like a personal savings account—but it’s designed specifically for healthcare costs.

Here’s how it works:

  • You contribute money pre-tax from your paycheck or on your own
  • You can use the funds anytime to pay for qualified medical expenses
  • Unused funds roll over year to year (they never expire)
  • ✅ You own the account—even if you change jobs or health plans
  • ✅ Some HSAs even let you invest your balance, growing your healthcare savings

  • Doctor visits & specialist copays

❓ FAQs About HSAs

💬 Can I invest the money in my HSA?

Yes—many HSAs allow you to invest your balance in mutual funds or ETFs once it exceeds a minimum (e.g., $1,000).

💬 Can I use HSA funds for my spouse or kids?

Yes, even if they’re not on your insurance—so long as you claim them as dependents.

💬 What happens if I use the HSA for non-medical expenses?

If you’re under age 65, you’ll owe income tax + 20% penalty. After age 65, the penalty disappears (though regular taxes still apply).
