Although the tax code refers to these plans as “health” savings accounts, an HSA can act as more than just a vehicle to pay medical expenses; it can also serve as a retirement account. For some taxpayers who have maxed out their retirement plan options, an HSA provides another resource for retirement savings—one that isn’t limited by income restrictions in the way that IRA contributions are.

Since there is no requirement that the funds be used to pay medical expenses, a taxpayer can pay medical expenses with other funds, allowing the HSA to grow (through account earnings and further tax-deductible contributions) until retirement. In addition, should the need arise, the taxpayer can still take tax-free distributions from the HSA to pay medical expenses. Unlike traditional IRAs, no minimum distributions are required from HSAs at any specific age. Withdrawals from an HSA that aren’t used for medical expenses are taxable and subject to a 20% penalty, with one exception: an individual age 65 or older will pay income tax on non-medical related distributions from their HSA but won’t owe a penalty for using the funds for other than medical expenses.
