Health savings accounts (HSAs), on the other hand, are accounts to which you and your employer can contribute money. However, you are eligible to contribute to an HSA only if you have a qualifying high-deductible health plan (HDHP). Your employer may offer an HDHP with an HSA as a workplace benefit. Or, if you sign up for individual health insurance coverage and choose an HDHP, you can open an HSA with a brokerage firm or other financial institution.
2. Taxes: With an HRA, your employer reaps the tax benefits since the company is the party contributing money. With an HSA, you reap the tax benefits. You can leave your HSA money invested from year to year, and it will grow tax-free if you don't take it out to pay for healthcare expenses. Also, the HSA is yours to keep even if you leave your job. However, if you withdraw funds for anything other than healthcare costs and you're younger than 65, you'll pay a 20% tax penalty on the money.
