How a Dependent Care FSA Works

A Dependent Care Flexible Spending Account (sometimes called a DCFSA or DCAP) lets you set aside money from your paycheck before taxes to pay for eligible dependent care expenses. The money comes out of your gross pay, which means it’s never subject to income tax or payroll tax.

The annual limit is $5,000 per household if you’re married filing jointly (or single). If you’re married filing separately, the cap drops to $2,500 per spouse. That $5,000 is a household limit, not per-child.

Tax Savings for LA Workers

The savings stack up fast in California. When you put $5,000 into a Dependent Care FSA, you avoid taxes at multiple levels:

• Federal income tax: At a 22% marginal rate, that’s $1,100 saved
• FICA taxes: 7.65% saves you $382.50
• California state income tax: At a 9.3% rate (common for LA earners in the $68,351–$78,950 bracket), that’s $465

Total potential savings: roughly $1,947 on a $5,000 contribution. That’s nearly 39 cents back on every dollar. For higher earners in the 32% federal bracket and 11.3% California bracket, the savings can top $2,500.

California Tax Treatment

Here’s something a lot of people don’t realize: California fully conforms to the federal Dependent Care FSA exclusion. Your DCFSA contributions reduce your California AGI the same way they reduce your federal AGI. Some states don’t follow federal rules here, but California does. That’s good news for LA workers — you get the state tax savings automatically.

The contributions also reduce your earnings for California SDI (State Disability Insurance) purposes, which is an additional small savings of about 1.1% on the contributed amount.

What Expenses Qualify

The rules mirror the Child and Dependent Care Credit requirements. Eligible expenses include:

• Daycare, preschool, and nursery school
• Before-school and after-school care
• Summer day camps
• Babysitter or nanny costs
• Care for a disabled spouse or dependent of any age who lives with you

The care must be necessary for you (and your spouse, if married) to work or look for work. Overnight camps, schooling for kids in kindergarten or above, and food or entertainment costs don’t qualify.

FSA vs. Child and Dependent Care Credit

You can’t double-dip. Every dollar you run through the Dependent Care FSA reduces your eligible expenses for the tax credit. So which is better?

For most LA families earning over $43,000 AGI (where the federal credit percentage bottoms out at 20%), the FSA wins. Here’s why: the FSA saves you at your marginal tax rate, which is almost always higher than 20%. Add in FICA and California taxes, and it’s not close.

The credit might be better if:

• Your AGI is under $25,000 (higher credit percentage)
• You’re self-employed and can’t access an FSA
• Your employer doesn’t offer a DCFSA

If you have two or more children and spend over $5,000 on care, you can use the FSA for the first $5,000 and claim the credit on up to $1,000 of additional expenses ($6,000 max minus $5,000 FSA).

Setting Up a DCFSA Through Your Employer

You can only enroll during your employer’s open enrollment period or within 30 days of a qualifying life event (new baby, marriage, spouse’s job change). Once you set your election, you generally can’t change it mid-year unless you have another qualifying event.

If Your Employer Doesn’t Offer One

You can ask HR to add it. DCFSAs cost employers very little to administer — in fact, they save the employer money because contributions aren’t subject to the employer’s share of FICA (7.65%). Many third-party benefits administrators can set one up quickly. It’s a legitimate win-win.

The Use-It-or-Lose-It Rule

Unlike health care FSAs, Dependent Care FSAs have no rollover and the $660 carryover option doesn’t apply. If you don’t spend the money by the end of the plan year (or the grace period, if your employer offers one), you forfeit it. Be conservative with your election if you’re unsure about your child care costs for the year.

Most plans offer a 2.5-month grace period after the plan year ends. So if your plan year is the calendar year, you’d have until March 15 to incur expenses against last year’s balance. Check your specific plan documents.
