Child & Dependent Care Credit Calculator

For families paying for care, the real question is whether the federal Child and Dependent Care Credit (CDCC) or a Dependent Care Flexible Spending Account (DCFSA) leaves more money in your pocket. The comparison here settles that instantly, and 2026 is the year the answer moved: the One Big Beautiful Bill Act (Pub. L. 119-21) raised the credit's top rate from 35% to 50% and lifted the DCFSA contribution limit from $5,000 to $7,500, both effective for tax years beginning after December 31, 2025.

The CDCC side applies an applicable percentage to your qualifying expenses, capped at $3,000 for one dependent or $6,000 for two or more. That percentage starts at 50% and falls one point for every $2,000, or fraction of $2,000, of AGI above $15,000, holding at a 35% floor once AGI passes $43,000. A second phasedown then runs 35% down to a 20% floor, one point per $2,000 of AGI above $75,000, or per $4,000 above $150,000 on a joint return, so 20% applies once AGI passes $103,000 single or $206,000 joint. At the 50% top rate the largest possible credit is $1,500 for one dependent and $3,000 for two or more. The DCFSA side applies your combined marginal rate, federal plus state plus the 7.65% FICA, to the pre-tax contribution limit of $7,500.

Two structural differences shape the outcome. The CDCC is non-refundable, so it can erase your tax liability down to zero but never pays out beyond that, whereas DCFSA contributions shrink your taxable income and can pull you into a lower bracket. And the two do not stack on the same dollar: IRC section 21(c) cuts your creditable expenses one for one by whatever you exclude through a DCFSA, so routing the full $7,500 through the account can leave nothing for the credit. The DCFSA also carries the use-it-or-lose-it rule, so estimate your care costs before committing money you can't recover.
