What is the difference between a Medical FSA and an HSA?

Q. What is the difference between a Medical FSA and an HSA?

A. Both FSAs and HSAs are tax-advantaged accounts that allow people to save money to pay for qualified medical expenses, but they have several key differences. The ACA implemented some new restrictions on FSAs and HSAs.

Flexible Spending Accounts (FSAs)

  • Established by an employer.
  • Usually funded by pre-tax payroll deduction, but employers can also contribute.
  • Can be used in conjunction with any type of health insurance, although health insurance coverage is not required.
  • FSA funds can be used to cover deductibles, copays and coinsurance, as well as qualified medical expenses that are not covered by health insurance, such as LASIK eye surgery. Prior to 2011, FSA funds could be used to purchase over-the-counter medications, but now they can only be used for OTC medications if a doctor has prescribed them (H.R.3762, passed by Congress in 2016 but vetoed by President Obama, would have removed the restriction on using FSA funds for OTC meds).
  • “Use it or lose it” – money not used by the end of the year (or by March 15th of the following year if the employer offers a grace period) is forfeited, although employers can allow enrollees to carry over up to $500 to the next year instead of allowing FSA funds to be used as late as March 15 of the following year.
  • In the past, employers could set their own FSA contribution limits for their employees. But the ACA limits contributions to no more than $2,650 in 2017 (in 2015 and 2016, the limit was $2,550, but there were inflation adjustments for 2017 and 2018). H.R.3762 would have eliminated the ACA’s contribution limits for FSA. The American Health Care Act, which passed in the House in 2017 but did not pass in the Senate, would have eliminated the contribution limits.
  • Contributions are deducted from each paycheck throughout the year.  However, the full annual contribution amount is available for use immediately (or after the first contribution is made).  If the employee uses the full amount and then quits or is terminated prior to the end of the year, FSA funds do not have to be paid back to the employer.

Health Savings Accounts (HSAs)

  • Can be established by an employer or by an individual, but only in conjunction with an HSA-qualified high deductible health plan (HDHP).
  • Contributions can only be made while the account holder remains covered by an HDHP.  However, the money can be used — without being taxed — for qualified medical expenses at any time in the future, even if the person is no longer covered by an HDHP.
  • Can be funded (pre-tax) by employee payroll deductions or employer contributions, or by an individual.
  • In 2018, maximum HSA contribution is $3,450 for a person with individual HDHP coverage, and $6,900 for those with family HDHP coverage. The IRS had initially set the family contribution limit at $6,900, but a bulletin published in March 2018 reduced the maximum contribution limit to $6,850. However, in April 2018, the IRS published Revenue Procedure 2018-27, which reverted to the original $6,900 family contribution limit for 2018.
  • If an HSA is established by an employer and the employee quits or is terminated, the HSA  goes with the employee, regardless of whether contributions were made by the employee or the employer.
  • Money in the HSA that is not used for medical expenses remains in the account.
  • HSA funds can be used for the same qualified medical expenses as FSA funds. And just like FSAs, prior to 2011, HSA funds could be used to purchase over-the-counter medications, but now a doctor’s prescription is required in order to use HSA money to buy OTC medications.
  • If money is withdrawn for qualified medical expenses, it is never taxed.
  • If money is withdrawn for other purposes prior to age 65, it is taxed and there is an additional 20 percent penalty applied. Prior to 2011, the penalty was 10 percent.
  • After age 65, money can be withdrawn without a penalty, but if it is not used for qualified medical expenses, income taxes will be owed.
  • Republican health care reform proposals have generally called for an increased focus on HSAs, with higher contribution limits and greater flexibility. But as of early 2018, none of those measures had been implemented. The GOP’s efforts to repeal the ACA in 2017 were unsuccessful, and the tax bill that Republican lawmakers passed in December 2017 did not make any changes to the rules pertaining to HSAs (it did repeal the ACA’s individual mandate, however, effective in 2019).
