The new $7,500 FSA limit against the up-to-50% child care credit
Updated October 2026
Public Law 119-21 changed both breaks for tax years beginning in 2026. The dependent care assistance exclusion under section 129, which sets the FSA limit, rose to $7,500 per household (it was $5,000 through 2025) ($3,750 if married filing separately); it is a fixed amount, not indexed. The child and dependent care credit under section 21 now starts at 50% instead of 35% and has a second phase-down that ends at 20%. The credit’s expense limits did not change: $3,000 for one qualifying person, $6,000 for two or more.
The rate starts at 50%, drops one point for each $2,000 (or part) of AGI over $15,000 until it reaches 35%, then drops again by one point per $2,000 ($4,000 on a joint return) over $75,000 ($150,000 joint) to a floor of 20%.
| AGI | Credit rate, single or head of household | Credit rate, married filing jointly |
|---|---|---|
| $40,000 | 37% | 37% |
| $60,000 | 35% | 35% |
| $100,000 | 22% | 35% |
| $150,000 | 20% | 35% |
| $200,000 | 20% | 22% |
| $260,000 | 20% | 20% |
Married couple, AGI $100,000 before any FSA, two children in daycare, $12,000 of care costs, 5% state income tax.
Option A, $7,500 FSA. Federal tax falls by 12% of $7,500 = $900 (they stay in the 12% bracket), payroll tax by 7.65% = $573.75, state tax by 5% = $375: $1,848.75. The credit’s $6,000 limit is reduced by the $7,500 excluded, to zero, so there is no credit.
Option B, credit only. At $100,000 of joint AGI the rate is 35%; 35% of $6,000 = $2,100, and their tax is more than enough to absorb it.
The credit wins by $251. Splitting does not help: every FSA dollar removes a dollar from the credit’s limit, trading a 35% credit for 24.65% of savings, so the best answer is one end or the other.
Married filing jointly, two children, $12,000 of care costs, $7,500 FSA election, 5% state tax, 2026 federal brackets:
| Joint AGI | Credit rate | With $7,500 FSA | Credit only | Better |
|---|---|---|---|---|
| $45,000 | 35% | $1,699 | $1,280 | FSA |
| $70,000 | 35% | $1,849 | $2,100 | Credit |
| $100,000 | 35% | $1,849 | $2,100 | Credit |
| $150,000 | 35% | $2,599 | $2,100 | FSA |
| $200,000 | 22% | $2,599 | $1,320 | FSA |
| $300,000 | 20% | $2,749 | $1,200 | FSA |
At low incomes the credit can be worth more on paper than the family’s tax bill, and because it is not refundable the excess is lost, which is why the FSA wins at $45,000. In the 12% bracket the 35% credit on $6,000 beats the FSA. From the 22% bracket up (joint AGI above about $133,000 with the standard deduction), the FSA’s combined 34.65% on $7,500 is worth more than 35% on $6,000, and the credit’s second phase-down above $150,000 widens the gap.
Enter AGI as it would be without the FSA (the calculator subtracts the election itself), the care costs you will actually pay for the year, and the number of qualifying people. The FSA election is the amount you choose at open enrollment, up to $7,500; your employer may set a lower cap. Use your state’s marginal income tax rate, or 0 in a state without income tax; a few states do not exempt FSA contributions, so check yours.
Care must let you (and your spouse) work or look for work. It must be for a child under 13, or a spouse or dependent who cannot care for themselves and lives with you more than half the year. Day care, preschool, before- and after-school care and day camp count; overnight camp and kindergarten tuition do not. You cannot pay your spouse, the child’s parent, your own child under 19, or anyone you claim as a dependent. Married couples must file jointly for the credit, and qualifying costs cannot exceed the lower-earning spouse’s earned income (a full-time student or disabled spouse is treated as earning $250 a month, $500 with two or more qualifying people). The provider’s name and taxpayer ID go on Form 2441.
It assumes the election is fully spent, ignores Social Security benefits lost from lower FICA wages (a small effect), and does not split costs between spouses with separate employer plans. It does not model the earned-income limit, state child care credits, or the order in which nonrefundable credits use up your tax. If one spouse earns little, if you have both an FSA and a large credit at stake, or if your employer offers a dependent care subsidy, a tax professional can check the exact numbers on Form 2441.
Double counting. The same dollar cannot go through the FSA and the credit. Electing per parent. The $7,500 limit is per household, even if both spouses’ employers offer an FSA. The 13th birthday. Care after a child turns 13 no longer qualifies. Overfunding. Unspent FSA money is generally forfeited, although some plans allow a grace period. Assuming the old rules. Advice written before 2026 compares a $5,000 FSA with a 20% credit; the trade-off is different now.
