The child and dependent care credit is a federal credit for what a taxpayer pays for household services and for the care of a qualifying individual, but only where those costs are incurred to let the taxpayer be gainfully employed. It is a percentage of qualifying costs rather than a refund of them, and the percentage falls as income rises.
The operative sentence is short. Where there are one or more qualifying individuals with respect to an individual, there is allowed a credit against the tax imposed by that chapter for the taxable year equal to the applicable percentage of the employment-related expenses paid by that individual during the taxable year (26 U.S.C. 21(a)(1)).
The name is shared across jurisdictions. Several states run their own child and dependent care credits, usually computed off the federal one, under the same words. Everything below is the federal credit.
The Applicable Percentage Falls in Two Stages, Not One
This is the part most summaries flatten. For purposes of the credit sentence above, the applicable percentage means 50 percent, and then two separate reductions apply in sequence (26 U.S.C. 21(a)(2)).
The first reduction cuts it, but not below 35 percent, by 1 percentage point for each $2,000 or fraction of $2,000 by which adjusted gross income for the taxable year exceeds $15,000 (26 U.S.C. 21(a)(2)).
The second reduces it further, but not below 20 percent, by 1 percentage point for each $2,000, or $4,000 in the case of a joint return, or fraction of that amount, by which adjusted gross income exceeds $75,000, or $150,000 in the case of a joint return (26 U.S.C. 21(a)(2)).
Two things about that structure are easy to lose. There are two floors, 35 percent and then 20 percent, not one. And the first stage has no joint-return variant: the doubled figures appear only in the second stage. The income being measured is adjusted gross income, not taxable income.
The Date Qualifier on That Percentage
The 50 percent figure is not old law. The amendment that produced it was enacted on July 4, 2025, and it applies to taxable years beginning after December 31, 2025 (26 U.S.C. 21, Effective Date of 2025 Amendment note). A return for an earlier year runs on the earlier percentages.
Who Is a Qualifying Individual
For purposes of that section the term covers three cohorts, and the second and third are not children (26 U.S.C. 21(b)(1)).
The first is a dependent of the taxpayer, as defined in section 152(a)(1), who has not attained age 13 (26 U.S.C. 21(b)(1)(A)). The second is a dependent of the taxpayer, as defined in section 152 determined without regard to subsections (b)(1), (b)(2) and (d)(1)(B), who is physically or mentally incapable of caring for himself or herself and who has the same principal place of abode as the taxpayer for more than one-half of the taxable year (26 U.S.C. 21(b)(1)(B)). The third is the spouse of the taxpayer, if the spouse is physically or mentally incapable of caring for himself or herself and who has the same principal place of abode as the taxpayer for more than one-half of the taxable year (26 U.S.C. 21(b)(1)(C)).
Note what the second and third share and the first does not: an abode test for more than half the year, and an incapacity test. Whether a child meets the dependency definition at all is the subject of qualifying child.
What Counts as an Employment-Related Expense
Two categories qualify, expenses for household services and expenses for the care of a qualifying individual, but only if they are incurred to enable the taxpayer to be gainfully employed for a period in which there are one or more qualifying individuals (26 U.S.C. 21(b)(2)(A)). The gainful-employment purpose is a condition on both categories, not a separate test bolted on afterwards.
One exclusion sits in the same subparagraph. The term does not include any amount paid for services outside the taxpayer’s household at a camp where the qualifying individual stays overnight (26 U.S.C. 21(b)(2)(A)).
Care bought outside the home is narrower again. Expenses incurred for services outside the taxpayer’s household are taken into account only if incurred for the care of a qualifying individual in the first cohort, the under-13 dependent, or of a qualifying individual not in that cohort who regularly spends at least 8 hours each day in the taxpayer’s household (26 U.S.C. 21(b)(2)(B)).
A dependent care center adds two more conditions on top of that one. Expenses for services provided outside the household by such a center are taken into account only if the center complies with all applicable laws and regulations of a State or unit of local government, and the outside-the-household requirements above are met (26 U.S.C. 21(b)(2)(C)).
The definition of a center is mechanical rather than descriptive. A dependent care center means any facility that provides care for more than six individuals, other than individuals who reside at the facility, and that receives a fee, payment or grant for providing services for any of the individuals, whether or not it is operated for profit (26 U.S.C. 21(b)(2)(D)).
Two Ceilings Sit Above the Percentage
The first is a dollar cap on what can be counted. The employment-related expenses taken into account may not exceed $3,000 where there is one qualifying individual, or $6,000 where there are two or more (26 U.S.C. 21(c)).
That cap is then reduced, and this is the sentence that connects the credit to the employer benefit. Whichever amount applies is reduced by the aggregate amount excludable from gross income under section 129 for the taxable year (26 U.S.C. 21(c)). Money already run through the employer plan covered under dependent care benefits comes straight off the ceiling, so the two cannot be stacked on the same dollars.
The second ceiling is earned income. Except as otherwise provided in that subsection, the expenses taken into account may not exceed the individual’s own earned income for the year where the individual is not married at the close of the year, or the lesser of the individual’s earned income and the spouse’s earned income where the individual is married at the close of the year (26 U.S.C. 21(d)(1)).
The exception the opening words point at is a deeming rule for a student or incapacitated spouse. For each month in which such a spouse is a full-time student at an educational institution, or is a qualifying individual in the third cohort, the spouse is deemed to be gainfully employed and to have earned income of not less than $250 where the one-individual dollar cap applies, or $500 where the two-or-more cap applies, and the rule applies to only one spouse for any one month (26 U.S.C. 21(d)(2)).
Student is a defined term rather than an ordinary one. It means an individual who during each of 5 calendar months during the taxable year is a full-time student at an educational organization (26 U.S.C. 21(e)(7)), and educational organization means one described in section 170(b)(1)(A)(ii) (26 U.S.C. 21(e)(8)). Four months of full-time study does not reach it.
The Filing and Identification Rules That Deny the Credit Outright
Married taxpayers generally have to file jointly. Where the taxpayer is married at the close of the taxable year, the credit is allowed only if the taxpayer and the spouse file a joint return for the year (26 U.S.C. 21(e)(2)). A person legally separated under a decree of divorce or of separate maintenance is not considered married (26 U.S.C. 21(e)(3)).
There is a route out for a married person living apart, with four elements that all have to hold. The individual must be married and filing a separate return, must maintain as a home a household that is for more than one-half of the taxable year the principal place of abode of a qualifying individual, must furnish over half the cost of maintaining that household during the year, and during the last 6 months of the year the spouse must not be a member of that household (26 U.S.C. 21(e)(4)). Only then is that individual not considered married. The interaction with filing status is what decides whether the credit survives a separation year.
Two identification rules deny the credit rather than reduce it. No credit is allowed for any amount paid to any person unless the name, address and taxpayer identification number of that person are on the return, or, where the person is an organization described in section 501(c)(3) and exempt under section 501(a), unless the name and address are on the return (26 U.S.C. 21(e)(9)). That sentence carries its own relief: where there is a failure to provide the information required, the denial does not apply if it is shown that the taxpayer exercised due diligence in attempting to provide the information so required (26 U.S.C. 21(e)(9)).
The second is simpler and has no relief clause. No credit is allowed with respect to any qualifying individual unless that individual’s TIN is on the return claiming the credit (26 U.S.C. 21(e)(10)).
Questions Firms Ask
Not now. It was made refundable for a single window, taxable years beginning after December 31, 2020 and before January 1, 2022, and then only where the taxpayer, or either spouse on a joint return, had a principal place of abode in the United States for more than one-half of the taxable year (26 U.S.C. 21(g)). The same temporary rule raised the dollar caps for that window (26 U.S.C. 21(g)). Both lapsed.
No. They are separate provisions with separate tests. This credit turns on amounts actually paid for household services or for the care of a qualifying individual, and only where those amounts were incurred to enable the taxpayer to be gainfully employed (26 U.S.C. 21(b)(2)(A)). A credit that does not turn on care being paid for is a different section, and a client can be inside one and outside the other in the same year.
Some relatives are excluded outright, and the exclusion is drawn by two specific tests rather than by relationship in general. No credit is allowed for any amount paid to an individual with respect to whom, for the taxable year, a deduction under section 151(c) is allowable to the taxpayer or the taxpayer’s spouse, or to an individual who is a child of the taxpayer within the meaning of section 152(f)(1) who has not attained the age of 19 at the close of the taxable year (26 U.S.C. 21(e)(6)). For that paragraph, taxable year means the taxpayer’s taxable year in which the service is performed (26 U.S.C. 21(e)(6)).
A grandparent is outside both tests unless the taxpayer claims them as a dependent. Where a relative is payable, the provider identification rule still applies in full, so the name, address and taxpayer identification number have to reach the return (26 U.S.C. 21(e)(9)).
It removes the amount entirely. Amounts paid for services outside the household at a camp where the qualifying individual stays overnight are not employment-related expenses at all (26 U.S.C. 21(b)(2)(A)), so the exclusion is not a proration.
Accountably places trained offshore accountants inside US CPA and EA firms, and a firm whose reviewers keep sending returns back over missing provider identification numbers can grade a real block of that preparation work through a trial task before it touches a live client file.
