Dependent Care Flexible Spending Accounts (DCFSA) are tax-advantaged accounts that let you use tax-free money to pay for eligible dependent care expenses. A qualifying “dependent” may be a child under 13, a disabled spouse, or another dependent who is physically or mentally unable to care for themselves.

Once enrolled, you can reimburse yourself for eligible dependent care expenses incurred during the plan year. DCFSAs are easy to use, but there are some important rules to keep in mind.

#1 Contribution limits apply

The IRS sets an annual contribution limit for DCFSAs. The annual household limit is $5,000 ($2,500 if married filing separately). Check this page for the current year's limits.

#2 Account funds are available only as you make contributions

Unlike a healthcare FSA, which front-loads your full election at the start of the plan year, a DCFSA only makes funds available as your payroll contributions are deposited. This means you can only be reimbursed up to the amount currently in your account.

#3 Unused funds return to the plan

DCFSAs are “use-it-or-lose-it” accounts. Any funds remaining at the end of the plan year (plus any grace period your employer offers) are forfeited back to the plan. Plan your eligible dependent care expenses carefully to maximize your savings.

#4 Election amounts can only be made during annual enrollment, unless you have a qualifying life event

You choose your DCFSA contribution amount during your employer's annual open enrollment period. Once set, you generally cannot change your election mid-year unless you experience a qualifying life event such as marriage, birth of a child, or change in employment status.

#5 Documentation from a babysitter is usually required

When filing claims for dependent care, you'll typically need to provide documentation from your care provider, including their name, address, and tax identification number (TIN) or Social Security number. This applies even for informal care providers like babysitters.

Unlike traditional FSAs, DCFSAs have unique rules around fund availability and contribution timing. Understanding these five rules will help you get the most from your benefit.
