Dependent care FSA or child care credit in 2026? Worked examples by tax bracket
Two things changed for child care costs in 2026. A dependent care FSA can now take $7,500 a year, up from $5,000, and the child and dependent care credit starts at 50% instead of 35% for lower incomes. You can use both, but not on the same dollar: whatever the FSA pays comes off the $3,000 (one child) or $6,000 (two or more) the credit is figured on. So at open enrollment, the question is how much to put in the FSA. Every figure below comes from our dependent care FSA calculator, which was checked against an independent model of the tax rules for 417 households. The families are examples: use your own numbers.
The two rules
The FSA takes money out of your pay before federal income tax, state income tax (in most states) and FICA. Each dollar saves your federal bracket + your state rate + 7.65% (1.45% on pay above the $184,500 Social Security wage base). The limit is $7,500 a household ($3,750 if married filing separately), no more than the lower earner's earned income. Money you don't spend by the end of the plan year can be forfeited.
The credit is a percentage of up to $3,000 of care costs for one child or $6,000 for two or more, minus whatever the FSA paid. The percentage depends on AGI (26 U.S.C. §21, as amended by P.L. 119-21):
| AGI | Married filing jointly | Single or head of household |
|---|---|---|
| $15,000 or less | 50% | 50% |
| $25,000 | 45% | 45% |
| $35,000 | 40% | 40% |
| $43,001 to $75,000 | 35% | 35% |
| $85,000 | 35% | 30% |
| $100,000 | 35% | 22% |
| $103,001 to $150,000 | 35% | 20% |
| $160,000 | 32% | 20% |
| $175,000 | 28% | 20% |
| $200,000 | 22% | 20% |
| Over $206,000 | 20% | 20% |
The rate drops one point for each $2,000 (or part of $2,000) of AGI over $15,000 until it reaches 35%, then one point for each $2,000 over $75,000, or each $4,000 over $150,000 on a joint return, until it reaches 20%. The credit is nonrefundable: it can't be more than your federal income tax.
Two children, $15,000 of child care
A married couple filing jointly, AGI $120,000, 5% state tax, both earning well over $7,500. The credit rate is 35%, so the credit alone is 35% of $6,000: $2,100. What a full $7,500 FSA saves depends on their federal bracket:
| Federal bracket | Credit only | $7,500 FSA | Better |
|---|---|---|---|
| 10% | $2,100 | $1,698.75 | Credit, by $401.25 |
| 12% | $2,100 | $1,848.75 | Credit, by $251.25 |
| 22% | $2,100 | $2,598.75 | FSA, by $498.75 |
| 24% | $2,100 | $2,748.75 | FSA, by $648.75 |
The state matters too. In the 12% bracket, with no state income tax the FSA saves only $1,473.75; at a 9.3% state rate it saves $2,171.25, and the FSA wins by $71.25.
At AGI $250,000 the credit rate is 20%, so the credit alone is only $1,200, while the FSA saves $2,748.75 in the 24% bracket, $3,348.75 at 32% and $3,573.75 at 35% (with 5% state tax and the full 7.65% FICA).
Why splitting is usually the worst choice
With two children and costs over $6,000, each FSA dollar up to $6,000 saves your combined tax rate but takes a dollar off the credit base, costing the credit rate. So in the 12% bracket (24.65% combined), each of those dollars loses 10.35 cents; in the 22% bracket (34.65%), it still loses 0.35 cents. Only the last $1,500 above $6,000 is pure gain. The totals for the 22% family:
| FSA election | $0 | $3,000 | $6,000 | $7,500 |
|---|---|---|---|---|
| Total saved | $2,100 | $2,089.50 | $2,079 | $2,598.75 |
So the best answer is nearly always all or nothing: $0 or as much as you can. The exceptions come from the credit's AGI steps (the FSA lowers your AGI) and from a tax bill smaller than the credit, which is why the calculator tries every dollar instead of just the two ends.
One child
With one child, the credit is figured on at most $3,000, 35% of it is $1,050, and the FSA can cover up to $7,500. The same $120,000 family with $15,000 of costs does better with the full FSA in every bracket: $1,698.75 at 10%, $1,848.75 at 12%, $2,598.75 at 22%. With only $5,000 of costs, the FSA can take $5,000 and saves $1,732.50 in the 22% bracket, against $1,050 from the credit.
A quick break-even rule
If your costs are at least $7,500 and your credit rate doesn't change, compare your combined rate (federal + state + FICA) with the credit rate:
- Two or more children: the full FSA wins when your combined rate is more than 0.8 × the credit rate. At 35%, that is 28%; at 20%, 16%.
- One child: when it is more than 0.4 × the credit rate. At 35%, 14%, so almost always.
Check with your own numbers in the calculator: it applies the lower-earner limit, your plan's FSA limit, the AGI steps and, if you enter it, your federal tax before credits. And elect only costs you're sure of: unlike the credit, unspent FSA money can be lost.
