Child care is one of the largest household expenses for working parents, and the tax code offers two mechanisms to offset the cost: the Dependent Care Flexible Spending Account (DC-FSA) and the Child and Dependent Care Tax Credit. Understanding how each works -- and how they interact -- can save a family thousands of dollars per year.
Dependent Care FSA (DC-FSA)
A DC-FSA is an employer-sponsored benefit that lets you set aside pre-tax dollars for qualifying dependent care expenses. The 2026 contribution limit is $5,000 per household ($2,500 if married filing separately).
At a 22% federal rate plus a 6% state rate, contributing $5,000 saves you 28% = $1,400 in income taxes, plus the FICA exemption adds roughly $382 more. Total tax savings on a $5,000 contribution: approximately $1,782.
Eligible expenses: daycare, after-school programs, summer day camps (not overnight), in-home childcare (nannies, au pairs), and care for a dependent who is incapable of self-care.
The "use it or lose it" rule applies -- unused funds are forfeited at year-end unless your plan offers a grace period or rollover (up to $640 in 2026).
Child and Dependent Care Tax Credit
For 2026:
- Maximum qualifying expenses: $3,000 for one qualifying person, $6,000 for two or more
- Credit percentage: 20% to 35% depending on AGI. At 20% of $6,000, the maximum credit for most households is $1,200
How They Interact: You Cannot Double-Count
Expenses reimbursed through a DC-FSA cannot also be used to claim the Child and Dependent Care Tax Credit. You must subtract your DC-FSA reimbursements from the maximum eligible expenses before calculating the credit.
Example: Two children in daycare costing $14,000/year. You contribute $5,000 to a DC-FSA. For the credit, maximum qualifying expenses are $6,000 minus the $5,000 DC-FSA use = $1,000 eligible. At 20%, the credit is $200. Total benefit: $1,782 + $200 = $1,982.
Which Is Better?
For most households in the 22% bracket or above, the DC-FSA provides a larger benefit because it saves taxes at your marginal rate plus FICA, while the credit tops out at 20% for most income levels. If your employer does not offer a DC-FSA, the credit is your only option. See the Child Tax Credit guide for information on the separate Child Tax Credit.
