Dependent Care FSA Tax Savings Calculator
Calculate federal, state, and FICA tax savings from maxing out your Dependent Care FSA.
Dependent Care FSA Basics
A Dependent Care FSA (DCFSA) is an employer-sponsored, pre-tax account for childcare expenses. You contribute up to $5,000/year ($2,500 if MFS) through payroll deduction. Funds avoid federal income tax, state income tax, AND FICA — making it the most tax-efficient way to pay for childcare for most families. Source: IRS Section 129, Publication 503. Last updated: May 2026.
What Qualifies as Dependent Care Expense
(1) Daycare for children under 13. (2) Preschool. (3) Summer day camp (not overnight). (4) Before/after-school programs. (5) In-home nanny or au pair (with tax compliance). (6) Adult dependent care for incapacitated spouse or parent who lives with you. NOT covered: overnight camp, kindergarten and above grade-level tuition, transportation, food.
DCFSA vs Child & Dependent Care Tax Credit
You can't use both on the same expenses. The FSA usually wins for AGI above $43,000 (where the credit rate drops to 20%). The credit may win for lower-income families because it's partially refundable (you get cash even with no tax liability). Run both calculators.
Use-It-Or-Lose-It Risk
Unspent DCFSA dollars at year-end (or grace period if employer offers one) are forfeited. Conservative approach: contribute slightly less than expected expenses ($4,500 if you expect $5,200 in childcare). The savings on $4,500 ($1,300+) still exceeds forfeiture risk.
Frequently Asked Questions
What is the 2026 Dependent Care FSA limit?
$5,000 per household for Single and MFJ filers. $2,500 if filing as MFS. Limit has not been adjusted for inflation since 1986 \u2014 major missed opportunity for inflation indexing by Congress.
Can both spouses have a DCFSA?
No. The $5,000 limit is per household, not per person. If both employers offer DCFSA, you can't double-stack. Choose whichever employer's DCFSA you prefer (slightly better administration usually).
What if I have unused DCFSA at year-end?
Most plans have a 2.5-month grace period (claims from January 1 to March 15 of next year). Some plans allow a $610 carryover (per IRS rules). Beyond that, unspent funds are forfeited to the employer. Plan contributions carefully.
Does DCFSA affect Social Security benefits?
Slightly. DCFSA reduces FICA wages, which marginally reduces your Social Security earning record. For a $5,000 DCFSA over 30 years, the SS benefit reduction is approximately $5-$15/month at retirement. The current tax savings vastly outweigh this.
Can I use DCFSA for summer camp?
Yes for DAY camp (kids return home each night). NOT for overnight camp. Specialty day camps (sports, art, music) qualify. The IRS considers any program that provides care during work hours and isn't overnight to be qualifying.
Can I use DCFSA for kindergarten tuition?
No. Kindergarten and above grade-level tuition is considered EDUCATIONAL, not custodial care. Doesn't qualify. Pre-K and preschool DO qualify because they're considered custodial. The line is murky in some districts \u2014 IRS Pub 503 clarifies.
