What is a Health Flexible Spending Account (FSA)?

When it comes to paying for medical expenses tax-free, most people know about Health Savings Accounts (HSAs), but Health Flexible Spending Accounts (FSAs) are another popular option, especially for employees with traditional health plans.

FSAs can help reduce your out-of-pocket healthcare costs and lower your taxable income, but they work differently than HSAs. Let’s take a closer look.

Health Flexible Spending Account (FSA): A Quick Definition

A Health Flexible Spending Account is a special employer-sponsored benefit that allows employees to set aside pre-tax dollars to pay for eligible out-of-pocket medical expenses. These can include:

  • Copays
  • Prescriptions
  • Dental and vision expenses
  • Over-the-counter health items

The money you contribute isn’t taxed, which means you can stretch your dollars further on everyday healthcare costs.

Key Features of Health FSAs

✅ Tax-Free Contributions

Money goes into your FSA before federal (and often state) taxes are applied. This reduces your taxable income and saves you money.

✅ Immediate Access

Unlike HSAs, the full annual contribution amount is available on day one of the plan year—even if you haven’t made all your payroll contributions yet.

⚠️ “Use-It-or-Lose-It” Rule

Most FSAs have a spending deadline, typically the end of the plan year. Some employers offer:

  • A short grace period (usually 2.5 months)
  • Or the ability to roll over up to $680 (2026 limit) into the next year

Any unused funds beyond that are forfeited.

2026 Health FSA Contribution Limits

For 2026, the IRS allows employees to contribute up to $3,400 to a health FSA. The IRS may adjust this limit each year based on inflation.

Employers can also contribute to an employee’s FSA, though total combined contributions are subject to the same cap.

Who Should Consider a Health FSA?

FSAs are a good fit if:

  • You don’t have an HDHP, and therefore can’t use an HSA
  • You expect predictable medical expenses (like prescriptions or regular doctor visits)
  • Your employer offers one, and you’re comfortable tracking your spending

If used wisely, FSAs can provide meaningful savings without changing your health insurance plan.
