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 (CDCTC). Understanding how each works -- and how they interact -- can save a family thousands of dollars per year. For most households in the 22% bracket or above, the DC-FSA delivers the larger benefit.
Dependent Care FSA (DC-FSA): The Basics
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). Contributions come out of your paycheck before federal income tax, state income tax, and FICA taxes are applied.
Tax savings example at a 22% federal rate plus 6% state rate:
- DC-FSA contribution: $5,000
- Income tax savings (28%): $1,400
- FICA savings (7.65% on $5,000): $383
- Total tax savings: approximately $1,783
This is a guaranteed, risk-free return on dollars you were going to spend on child care anyway.
What Expenses Qualify for the DC-FSA
Eligible expenses must be for the care of a qualifying person (a dependent child under age 13, or a dependent or spouse incapable of self-care) so that you -- and your spouse, if married -- can work or look for work:
- Licensed daycare centers and preschools
- Before-school and after-school programs
- Summer day camps (not overnight camps)
- In-home childcare: nannies, au pairs, babysitters (if they care for a qualifying person)
- Adult day care for a qualifying dependent who cannot care for themselves
Expenses that do not qualify include overnight camps, tuition for kindergarten and above, tutoring, and care provided by a dependent or your spouse.
The "Use It or Lose It" Rule
Unused DC-FSA funds are forfeited at plan year-end -- they do not roll over to the next year. However, your employer's plan may offer either a grace period (up to 2.5 months after year-end to incur eligible expenses) or a carryover option (up to $640 in unused funds carried to the next plan year in 2026). Check your specific plan documents. Do not contribute more than you are confident you will spend on qualifying care during the plan year.
Child and Dependent Care Tax Credit (CDCTC)
The Child and Dependent Care Tax Credit is a non-refundable federal tax credit available to taxpayers who pay for qualifying dependent care. For 2026:
- Maximum qualifying expenses: $3,000 for one qualifying person, $6,000 for two or more qualifying persons
- Credit percentage: 20% to 35% of qualifying expenses, depending on AGI. The 35% rate applies to AGI below $15,000; the rate phases down to 20% for AGI above $43,000 (where most working parents land)
- At 20% of $6,000, the maximum credit for most households is $1,200
How the DC-FSA and CDCTC Interact: You Cannot Double-Count
This is the most important planning point. Expenses reimbursed through a DC-FSA cannot also be used to claim the Child and Dependent Care Tax Credit. You must reduce the maximum eligible expenses for the CDCTC by the amount you received from a DC-FSA.
Example with two children:
- Total daycare costs: $14,000
- DC-FSA reimbursement: $5,000
- CDCTC maximum qualifying expenses: $6,000 minus $5,000 = $1,000 remaining
- Credit at 20%: $200
- Total tax benefit: $1,783 (DC-FSA) + $200 (CDCTC) = $1,983
Compare this to using only the CDCTC with no DC-FSA: 20% of $6,000 = $1,200. The DC-FSA delivers $783 more in tax savings for this household, primarily because it saves FICA taxes in addition to income taxes.
When the CDCTC Is Larger Than the DC-FSA Benefit
For households in the 10% or 12% income tax bracket, the CDCTC's 20% credit rate may exceed the income tax savings from the DC-FSA (since the FSA only saves 10% or 12% on the income tax side). In these cases, the choice is less clear-cut and depends on whether FICA savings tip the balance. If your employer does not offer a DC-FSA at all, the CDCTC is your only option.
Dependent Care FSA vs. Child Tax Credit: These Are Different
The Dependent Care FSA and Child and Dependent Care Tax Credit are specifically for care expenses that allow you to work. They are entirely separate from the Child Tax Credit, which is a per-child credit that does not require care expenses. A family can claim the DC-FSA benefit, the CDCTC, and the Child Tax Credit simultaneously -- they address different aspects of the tax code. See the Child Tax Credit guide for details on that separate credit.
Nanny Tax Considerations
If you hire an in-home caregiver (nanny, au pair, or babysitter) and pay them $2,700 or more in 2026, you become a household employer subject to the "nanny tax." You are required to withhold Social Security and Medicare taxes from their wages, pay the employer's share of FICA, and potentially pay federal and state unemployment taxes. Expenses for a household employee are eligible for the DC-FSA if the care is for a qualifying person, but you must comply with employer tax obligations. IRS Schedule H is used to report household employment taxes.
How to Enroll in a DC-FSA
DC-FSAs are employer-sponsored benefits. Enrollment typically occurs during your employer's open enrollment period (usually in the fall for the following plan year) or within 30 days of a qualifying life event (birth, adoption, change in care needs). You must elect your contribution amount at enrollment -- you cannot change it mid-year except after a qualifying event. If your employer does not offer a DC-FSA, you can only use the CDCTC.

Common DC-FSA Mistakes and How to Avoid Them
The most frequent DC-FSA error is over-contributing. Because unused funds are forfeited, contributing $5,000 when you only have $3,500 in qualifying care expenses costs you money. Before open enrollment, estimate your actual expected care costs conservatively. If your care situation changes mid-year (a child ages out, a caregiver leaves), you can adjust contributions only after a qualifying life event.
A second common mistake is using DC-FSA funds for ineligible expenses. Tuition for kindergarten through grade 12 is not eligible, even if the child attends a private school. Overnight camps are not eligible, even if they operate during the summer. If you accidentally pay an ineligible expense with DC-FSA funds, you will owe income tax and a 20% penalty on that amount.
Third: forgetting to submit claims before the plan deadline. Many plans have a run-out period after the plan year ends during which you can submit claims for expenses incurred during the plan year. If you miss this deadline, you forfeit the funds even if the expense was eligible. Set a calendar reminder for your plan's claim submission deadline -- typically 90 days after year-end.
DC-FSA for Care of Adult Dependents
The DC-FSA is not limited to child care. If you have a spouse or dependent who is physically or mentally incapable of self-care and lives with you, expenses for their daytime care while you work are also eligible. Adult day care centers that provide medical or custodial care qualify. This is an often-overlooked benefit for adult children with disabilities or elderly parents who meet the dependency and self-care requirements.
