Dependent Care FSA

A dependent care FSA is an employer-sponsored account funded by payroll election, up to $5,000 per household per year ($2,500 for married filing separately), spent on childcare that lets both spouses work: daycare, preschool, after-school care, and summer camps. The deductions skip income tax and the 7.65% FICA line, a combined 29.65% saving at a 22% bracket, roughly $1,483 on the full $5,000. The account is use-it-or-lose-it, and expenses must be incurred inside the plan year.

The account interacts with the child and dependent care credit, and the same expenses cannot fund both; claiming the FSA and the credit on the same dollars triggers IRS matching. Below roughly $43,000 of income the credit is worth more than the FSA's payroll saving, which is the comparison worth running. The election is made at open enrollment, and mid-year changes need a qualifying event.

The election runs through payroll: you pick up to $5,000 at open enrollment, payroll deducts it in equal slices before income tax and FICA, and the balance sits in the employer-owned account. A $5,000 election at a 22% bracket saves 29.65% of the amount, roughly $1,483 a year. The same $5,000 of childcare paid by direct deposit owes both tax lines first.

The spending runs on receipts or the FSA debit card against qualifying care: daycare, preschool, before and after-school programs, nanny wages with a tax ID, and day camps, but not overnight camp or private school tuition below kindergarten. Both spouses must be working or looking for work for the expenses to qualify, and one spouse without earned income zeroes the benefit. The plan year is the deadline: expenses incurred outside it forfeit, with the employer's grace period if one is offered.

The credit interaction is the comparison. The child and dependent care credit covers the same expenses at 20% to 35% of up to $3,000 of spending for one dependent, and the same dollars cannot fund both; the FSA reduces the expenses available to the credit to zero once $5,000 is claimed. Below roughly $43,000 of adjusted gross income the credit's rate outruns the FSA's payroll saving, and above it the FSA wins. The IRS matching catches the duplicate claims.

Childcare is the second-largest line in most young household budgets, and the FSA is the 30% discount on it that most families leave unclaimed. The election is opt-in at open enrollment, the deadline is the plan year, and the forfeit is the price of optimism. The credit comparison is the other half of the decision.

I watched a colleague named Brent (yes, that Brent) elect the full $5,000 in January, switch his spouse to a stay-at-home arrangement in June, and meet the forfeit at year end: the expenses stopped qualifying when one spouse had no earned income, and $2,400 of the balance was gone. The saving on the $2,600 he did use was $771; the forfeit was the difference. The account prices the work requirement, not the optimism.

The highest-leverage thing most American families can do is elect conservatively against the work requirement and compare the credit at their income before open enrollment. Check the monthly arithmetic with the budget calculator, read the health version in the FSA entry, and see the credit side in the child tax credit entry.
