A health savings account (HSA) is a tax-advantaged medical savings account available to taxpayers in the United States who are enrolled in a high-deductible health plan. The funds contributed to an account are not subject to federal income tax at the time of deposit. Unlike a flexible spending account (FSA), HSA funds roll over and accumulate year to year if they are not spent. HSAs are owned by the individual, which differentiates them from company-owned Health Reimbursement Arrangements (HRA) that are an alternate tax-deductible source of funds paired with either high-deductible health plans or standard health plans.
HSA funds may currently be used to pay for qualified medical expenses at any time without federal tax liability or penalty. Beginning in early 2011 over-the-counter medications cannot be paid with an HSA without a doctor's prescription. Withdrawals for non-medical expenses are treated very similarly to those in an individual retirement account (IRA) in that they may provide tax advantages if taken after retirement age, and they incur penalties if taken earlier. The accounts are a component of consumer-driven health care.
A flexible spending account (FSA), also known as a flexible spending arrangement, is one of a number of tax-advantaged financial accounts, resulting in payroll tax savings. Before the Patient Protection and Affordable Care Act, one significant disadvantage to using an FSA was that funds not used by the end of the plan year were forfeited to the employer, known as the "use it or lose it" rule. Under the terms of the Affordable Care Act, a plan may permit an employee to carry over up to $500 into the following year without losing the funds.
The most common type of flexible spending account, the medical expense FSA (also medical FSA or health FSA), is similar to a health savings account (HSA) or a health reimbursement account (HRA). However, while HSAs and HRAs are almost exclusively used as components of a consumer-driven health care plan, medical FSAs are commonly offered with more traditional health plans as well. In addition, funds in an HSA are not lost when the plan year is over, unlike funds in an FSA. Paper forms or an FSA debit card, also known as a Flexcard, may be used to access the account funds.
