Health Savings Accoung (HSA)

A health savings account (HSA) is a tax-exempt trust or custodial account you set up with a qualified HSA trustee to pay or reimburse certain medical expenses.

A qualified HSA trustee can be a bank, an insurance company, or anyone already approved by the IRS to be a trustee of individual retirement arrangements (IRAs) or Archer MSAs. You can establish the HSA through a trustee that is different from your health plan provider.

Benefits of an HSA

  • You can claim a tax deduction for contributions you, or someone other than your employer, make to your HSA even if you do not itemize your deductions on Form 1040.
  • Contributions to your HSA made by your employer (including contributions made through a cafeteria plan) may be excluded from your gross income.
  • The contributions remain in your account until you use them.
  • The interest or other earnings on the assets in the account are tax free.
  • Distributions may be tax free if you pay qualified medical expenses.
  • An HSA is “portable.” It stays with you if you change employers or leave the work force.

To be an eligible individual and qualify for an HSA, you must meet the following requirements.

  • You must be covered under a high deductible health plan (HDHP), described in the next section, on the first day of the month.
  • You cannot be enrolled in Medicare.
  • You cannot be claimed as a dependent on someone else's tax return.
  • Each spouse who is an eligible individual who wants an HSA must open a separate HSA. You cannot have a joint HSA.

High deductible health plan (HDHP)

  • Has a higher annual deductible than typical health plans, and
  • Has a maximum limit on the sum of the annual deductible and out-of-pocket medical expenses that you must pay for covered expenses. Out-of-pocket expenses include copayments and other amounts, but do not include premiums.
