Child and dependent care credit

Two things about this credit changed for 2026, and both make it larger. The applicable percentage in IRC § 21(a)(2) was rewritten to start at 50 percent and step down through two ranges rather than one, and the companion exclusion in § 129 rose by half. Everything else — the expense caps, the earned income limitation, the joint return requirement — is where it has been for years.

The rule

The credit. Where there are one or more qualifying individuals, there is allowed a credit equal to the applicable percentage of the employment-related expenses paid during the taxable year (IRC § 21(a)(1)). It is nonrefundable — § 21 sits in subpart A of part IV, and nothing makes it refundable for 2026. The temporary refundability in § 21(g) was written for one year, 2021, and that subsection is still sitting in the Code doing nothing.

The applicable percentage. 50 percent, reduced by 1 percentage point for each $2,000 or fraction of adjusted gross income over $15,000 but not below 35 percent, then further reduced by 1 point for each $2,000 ($4,000 joint) of adjusted gross income over $75,000 ($150,000 joint) but not below 20 percent^TY2026 (IRC § 21(a)(2)(A), (B)). Read the two reductions as a single staircase with a flat landing: full rate up to the first breakpoint, a first decline to a middle floor, a plateau across the middle band, then a second decline to 20 percent — the credit never falls below one fifth of creditable expenses however high adjusted gross income goes^TY2026. Note the asymmetry — the first reduction uses the same step and the same starting point for every filing status, while the second uses a doubled step and a doubled starting point on a joint return.

Qualifying individual. under age 13 for a dependent qualifying by age; there is no age ceiling for a dependent or spouse who is physically or mentally incapable of self-care and shares the taxpayer's principal place of abode for more than half the year^TY2026 (IRC § 21(b)(1)(A)–(C)). For the incapacity limbs the dependency test drops § 152(b)(1), (b)(2) and (d)(1)(B), so someone who could not be a dependent because of their own gross income or a joint return can still be a qualifying individual. The spouse limb needs no dependency at all.

Employment-related expenses. Amounts paid for household services and for the care of a qualifying individual, but only if incurred to enable the taxpayer to be gainfully employed (IRC § 21(b)(2)(A)). The regulation supplies what the statute leaves out: expenses count for periods in which the taxpayer is gainfully employed or is in active search of gainful employment, employment includes self-employment, and “work as a volunteer or for a nominal consideration is not gainful employment” (Reg. § 1.21-1(c)(1)). A period only partly employed must be allocated daily, but a short temporary absence — two consecutive calendar weeks is short as a matter of the rule — needs no allocation if the arrangement requires payment through it (Reg. § 1.21-1(c)(2)(i), (ii)).

The expense cap. $3,000 of employment-related expenses for one qualifying individual and $6,000 for two or more — fixed, never indexed, and reduced by any amount excluded from gross income under IRC § 129^TY2026 (IRC § 21(c)). Two points here cost candidates marks. The cap is on expenses, not on the credit, so the maximum credit is the applicable percentage of the cap. And the cap for two or more qualifying individuals is a single pooled figure, not a per-child amount — expenses paid for one of two children can fill it entirely.

The earned income limitation. Creditable expenses cannot exceed the taxpayer’s earned income, or on a joint return the lesser of the two spouses’ earned incomes (IRC § 21(d)(1)(A), (B)). A married couple with one spouse out of the workforce therefore has a limitation of zero. Section 21(d)(2) softens that for one case only: a spouse who is a full-time student or is incapable of self-care is deemed gainfully employed with earned income of $250 a month if there is one qualifying individual and $500 a month if there are two or more, deemed earned income for a spouse who is a full-time student or is incapable of self-care^TY2026, for each month the condition holds. A student is someone who is a full-time student for each of five calendar months in the year (IRC § 21(e)(7)).

The special rules. A married taxpayer must file a joint return (IRC § 21(e)(2)), subject to the § 21(e)(4) test for a spouse living apart: the household must be the qualifying individual’s principal place of abode for more than half the year, the taxpayer must furnish over half the cost, and the other spouse must be absent for the last six months. Where § 152(e) applies to a child, the child is a qualifying individual of the custodial parent and not of the noncustodial parent, whichever of them claims the dependency (IRC § 21(e)(5)). No credit is allowed for amounts paid to the taxpayer’s own child under 19 at the close of the year, or to the taxpayer’s dependent (IRC § 21(e)(6)(A), (B)).

Two identification requirements, not one. No credit is allowed for an amount paid to a provider unless the provider’s name, address and taxpayer identification number are on the return — name and address only for a § 501(c)(3) organization — with a due diligence escape where the taxpayer tried and failed (IRC § 21(e)(9)). Separately, no credit is allowed with respect to a qualifying individual unless that individual’s TIN is on the return (IRC § 21(e)(10)), and that one has no escape.

The exclusion interacts with the credit. An employee may exclude dependent care assistance up to $7,500, or $3,750 on a separate return by a married individual, raised from $5,000 and $2,500 for taxable years beginning after 31 December 2025^TY2026 (IRC § 129(a)(2)(A)). Section 21(c) reduces the expense cap by the amount excluded, so the two cannot be taken on the same dollars — and because the exclusion now exceeds the credit’s cap for two children, a fully used exclusion can eliminate the credit.

Current figures

How it works in practice

Take the computation in four steps and in this order, because each step feeds the next.

Step one, count the expenses that qualify. Only amounts paid to enable gainful employment, only for periods of employment or active job search, and only to a permitted provider.

Step two, apply the expense cap — one figure for one qualifying individual, a larger pooled figure for two or more — and reduce that cap by anything excluded under § 129.

Step three, apply the earned income limitation. Compare the capped expenses to earned income, or on a joint return to the lesser of the two earned incomes, substituting deemed earned income for a student or incapacitated spouse.

Step four, multiply by the applicable percentage from adjusted gross income, then limit the result to the tax otherwise due, since the credit is nonrefundable.

The order matters because the § 129 reduction operates on the cap rather than on the expenses. A taxpayer with two children, expenses above the cap, and an exclusion equal to the cap has no creditable expenses at all, however large the actual outlay.

How this has changed

Pub. L. 119-21 § 70405 amended IRC § 21(a)(2) generally, for taxable years beginning after 31 December 2025. The Code’s own amendment note preserves what it replaced: a single applicable percentage of 35 percent, reduced but not below 20 percent, by one point for each step of adjusted gross income above one breakpoint. So before 2026 there was one starting rate, one breakpoint and one floor; from 2026 there is a higher starting rate, two breakpoints and a middle floor. Taxpayers in the band between the two breakpoints gain the most — their rate rises from the old floor to the new middle floor.

Pub. L. 119-21 § 70404 separately raised the § 129 exclusion, also for taxable years beginning after 31 December 2025 (the Act’s section numbers run the other way round from what the subject matter suggests, and the effective date notes on each section confirm which is which). Because § 21(c) reduces the credit cap by the exclusion, the larger exclusion also enlarges the group of employees for whom the credit is worth nothing.

Two pieces of dead text remain in the section and should not be mistaken for current law. Subsection (g) still contains the 2021 refundability rule, expressly limited to that one year. And § 21(e)(6)(A) still denies the credit for payments to a person for whom “a deduction under section 151(c)” is allowable — a personal exemption deduction whose amount has been zero since 2018, so the paragraph now operates through the dependency definition it points at rather than through any deduction actually taken.

Exam focus

The examiners test the definitions far more often than the arithmetic. Expect a question offering four situations and asking which is not work-related — the volunteer answer is the classic, and the regulation supports it in terms. Expect another on which income counts for the earned income limitation, where the pension option is the outlier. Know that the credit is nonrefundable for 2026, that a married taxpayer must file jointly, and that the credit belongs to the custodial parent regardless of who claims the dependency.

For computation, be able to run the four steps in order and to say why the § 129 exclusion reduces the cap rather than the expenses. Know that the cap for two or more qualifying individuals is pooled. And for 2026 specifically, know that the percentage starts higher and steps down twice — a candidate carrying the old single-breakpoint rule will under-state the credit for most middle-income taxpayers.

Check yourself

1. A taxpayer pays a neighbour to watch her 6-year-old while she does unpaid volunteer work at a food bank two days a week and works at a paid job three days a week. Which expenses are employment-related?

Answer: Only those for the three paid days. Reg. § 1.21-1(c)(1) states that work as a volunteer or for nominal consideration is not gainful employment, and § 1.21-1(c)(2)(i) requires expenses covering a period only partly employed to be allocated on a daily basis.

2. A married couple file separately. One spouse maintained a home that was the principal place of abode of their 5-year-old for the whole year, paid over half the cost of it, and the other spouse moved out in March. May that spouse claim the credit?

Answer: Yes. IRC § 21(e)(2) requires a joint return, but § 21(e)(4) treats a married individual as not married where all three of its conditions are met — the home test, the over-half-the-cost test, and the absence of the other spouse for the last six months of the year. A March departure satisfies the third.

3. Why can a taxpayer who pays $10,000 for the care of three children never take a credit on more than a fraction of it?

Answer: Because IRC § 21(c) caps creditable employment-related expenses at $6,000 where there are two or more qualifying individuals. The cap is pooled rather than per child, so a third child adds nothing, and the cap is further reduced by any amount excluded under § 129.

4. A grandmother is paid $4,000 to care for her daughter’s child. The grandmother is her daughter’s dependent. May the daughter claim the credit?

Answer: No. IRC § 21(e)(6)(A) denies the credit for any amount paid to an individual with respect to whom a dependency deduction is allowable to the taxpayer or the taxpayer’s spouse. Paying a dependent — or the taxpayer’s own child under 19 — never produces a credit, whatever the amount or the market rate.

5. What is the maximum credit for a single taxpayer with one qualifying individual, adjusted gross income of $300,000, and $5,000 of qualifying expenses?

Answer: $600. Expenses are capped at $3,000 for one qualifying individual under IRC § 21(c), and the applicable percentage cannot fall below 20 percent under § 21(a)(2)(B) however high adjusted gross income rises. There is no complete phase-out of this credit.
