As we head into fall, now is the perfect time to start thinking about your Flexible Spending Account.

Open enrollment in these accounts are generally held in the late fall, and in order to make the best use of them, you’ll need to do a little planning and research ahead of time.

Here is what you need to know in order to make the best use of your Flexible Spending Account (FSA).

What is a Flexible Spending Account?

Flexible Spending Account ContributionsIf you have never enrolled in one of these accounts, you may be missing out on some major savings.

A Healthcare Flexible Spending Account allows you to set aside pre-tax dollars from your paycheck to use for medical expenses, while a Dependent Care FSA allows you to set aside money for expenses like daycare for children under age 13 and care for elderly adults or disabled dependents.

The tricky aspect to FSAs is that they are a use-it-or-lose-it plan, which means you need to carefully estimate how much money you think you’ll need for these expenses over the year.

FSAs typically allow a grace period for you to use any funds still left over at the end of the year, but seriously over- or underestimating your needs for the year can be costly.

Estimating Expenses

Several websites, such as Kiplinger’s and WageWorks, offer calculators to help you determine how much money you should put away in your FSA.

In order to take full advantage of these calculators, you will need to gather some information to really help you get a clear view of next year’s needs.

That information includes:

  1. Last year’s FSA receipts if you still have them.
  2. A list of your regular prescriptions.
  3. An estimate of the number of times each member of the family visited the doctor this year. You can actually get a report from your insurance provider on how many medical claims each family member had last year.
  4. Any plans for future surgeries or procedures.

If you are mathematically inclined, you can further estimate the best use of your money by using a tool put together by The Finance Buff, who theorizes that “there has to be a point where losing a little pre-tax money in the FSA is less expensive than paying a lot with after-tax money.”

The spreadsheet he provides can help those who are watching every single penny maximize their money (using some of the math you might have forgotten since high school.)

See Your Doctor

If you suspect that you may need some costly procedures in the next year—or if you simply have not been to see your healthcare providers recently—it makes sense to schedule an appointment with your doctor and dentist prior to the open enrollment period for your FSA.

Your doctor can help you determine if you’ll need any special or elective care in the coming year, and you can budget the expense of it into your FSA plan.

Dependent Care FSA

Figuring out how much to put aside for dependent care tends to be a much easier proposition than doing the same for healthcare expenses since daycare costs are predictable.

However, it can be confusing determining whether you should use your Dependent Care FSA or take the childcare tax credit, as you cannot do both.

A general rule of thumb is that parents in higher tax brackets will benefit more from an FSA over the tax credit.

As the website Babycenter points out, “the more you earn, the more you’ll benefit from an FSA, particularly if you’re at or above the 25 percent federal tax bracket.

Taxpayers in the 15 percent federal tax bracket who have only one child and have qualified expenses of at least $3,000 may be best off with the FSA, too.”

Knowing your tax bracket will help you decide whether or not to use the Dependent Care FSA.

When estimating your childcare expenses for the year, don’t forget to include summer camp and after-school care, as those costs can also be covered by an FSA.

The Bottom Line

If you’ve been avoiding enrolling in an FSA because you are nervous about the use-or-lose-it rule, now is a perfect time to try it.

With a little research and planning, your FSA can save you money and headaches in 2019.

  1. Jim Hayes says

    Great post!

    For dependent care accounts remember that only summer day camp may be reimbursed, overnight camp is not eligible.

  2. Roger @ The Chicago Financial Planner says

    Good post, I recall doing this many times over the years. Time well-spent as this is an excellent benefit. We went to an HSA and high deductible account this year, will need to evaluate our spending to see if this was a good move or not during open enrollment for my wife’s employer this Fall.

  3. Kevin @ Ask For Benefits says

    People consistently under utilize FSA’s. One of the reasons is that they don’t understand how much they are saving: they overlook the FICA and state income tax savings and do the math wrong.

    Using an FSA eliminates state, federal, and FICA taxes – except in NJ. The rates employee pay is 5.65%, but most articles (including this one) do not mention this savings. Often people in mid range tax brackets save the most, as the FICA contribution drops to 1.45% once income exceeds a $110,100 (2012 limit).

    People do the math wrong on potential savings. Take this example. An employee saving 25% federal, 5.65% FICA, and 2% state taxes often add the savings to 32.65% and might multiply that by their contribution of $2,000 to estimate a savings of $641.30.

    What most people fail to see is the amount of after tax dollars they must earn to get the $2,000. The proper method is to divide the contribution amount by the savings percent to get the amount of gross income they must earn to yield the contribution amount they are spending anyway.

    $2,000/(1-32.65% )= $2,969

    In this example the employee would have to earn an additional $969 to have $2,000 to spend on these medical items. Employees seem to focus on the possibility of leaving $500 on the table, rather than the real savings.

    • Mike says

      Kevin, I didn’t realize that was the case in NJ. Does the employer save on FICA in NJ or is it excluded for everyone?

      Good points with calculating the amounts. I’m going to borrow this.

      • Kevin @ Savvy on Credit says

        NJ does not recognize any pre taxing for calculating state income tax. Check any W2 form and you will find that the NJ income is almost always higher. The difference is usually the pre tax amount deductions not recognized.

        Employers in NJ save the same on FICA as in any other state – as FICA is a federal program. The NJ exception applies to state taxation only.
