Depending on the kind of health insurance plan you have, you might be eligible for an HSA or an FSA account. Taking advantage of these kinds of accounts can help you save money and prepare for medical expenses that come up during the year.

HSAs and FSAs have different qualifications and advantages. Here is an overview of everything you need to know to help you understand the basics of HSA vs. FSA so that you can choose the best plan for you.

Health Savings Account (HSA)

An HSA is a savings account with tax advantages that can be used in combination with a High Deductible Health Plan. The funds in the HSA account are accumulated in order to be used for eligible medical expenses by the account holder. Health Savings Accounts have to be tied to High Deductible Health Plans (HDHP), they are not available if you are not enrolled in a qualified high deductible health plan. 

Qualified HDHPs Give You Access to Savings Options Through HSAs

An HDHP may make you uncomfortable if you are worried about coming up with money to cover the deductible and out of pocket expenses, but when you look at the key benefits you can take advantage of when you have a high deductible health plan and an HSA, it makes a lot of sense and puts you at an advantage. Two key elements are:

    If you build money into your HSA over a couple of years and have not had high medical expenses, you will save enough to compensate for the HDHP and save more money on your health plan overall.

    Benefits That Make HSAs a Really Good Idea

    Although HSAs have several benefits, as outlined in the comparison chart below, some key features are:

    • Any money you invest in your HSA can grow tax-free and if you do not spend it on medical costs, then you can keep accumulating these savings for retirement. 
    • Withdrawing money from an HSA to pay qualified medical expenses is tax-free. 
    • Earnings in HSAs are not taxed
    • If you don't have high medical or out of pocket medical expenses now, you aren't wasting or losing your money, the money builds up over time, so if all of a sudden you do need access to medical funds, you aren't limited to the yearly contribution, the money in the HSA will build over time.

    Flexible Spending Account or Flexible Spending Arrangement (FSA)

    Flexible Spending Arrangements, also called Flexible Spending Accounts, can be used for medical expenses and are not linked to HDHPs, so they can be used with any health plans and are usually offered by an employer as part of a benefits package. 

    FSA Money Expires at the End of the Year—No Long-Term Savings Potential

    You benefit from tax savings of the money you put in your FSA, the problem is, you won't be able to keep any funds left in it at the end of the year if you haven't used them. FSAs do not work well as a long-term savings strategy.*

    Saving on Your Taxes With HSA or FSA

    With HSAs and FSAs you benefit from tax savings because you can have your money put into your account by your employer or administrator "pre-tax." 

    Can You Have an HSA and an FSA at the Same Time?

    You can only have an HSA and an FSA at the same time if the FSA is designated as a "limited purpose FSA (LPFSA)." LPFSAs must have a specified purpose, for example when the LPFSA is designated to cover dental and vision costs, and not the regular medical expenses being covered by the HSA. 

    Eligible HSA and FSA Expenses

    HSAs and FSAs are meant to cover eligible health expenses. Some examples of how people may use their funds may include copayments, deductibles, some drugs, as well as many other eligible health care costs. Eligible expenses can be seen on page 8 of form 969Health Savings Accounts and Other Tax-Favored Health Plans. Your plan administrator or employer may be able to help you understand the qualified expenses for your health plan.

    An HSA or FSA: Which Is Better?

    Overall an HSA is more flexible, allows you to save money by paying fewer taxes, but also allows you to save money long term since whatever you don't use in any given year will roll over and accumulate as savings over time.

    The FSA does not build over time, you lose any amount you put into it at the end of the year, so it is not a long-term savings tool. You also stand to lose your FSA if you change employer, but it still provides the tax savings, so if you don't qualify for an HSA, and you don't have an HDHP the FSA is a good option.
