IRC Section 129: Limits, W-2 Reporting, and Employer Rules

Internal Revenue Code Section 129 lets you exclude employer-provided dependent care assistance from your taxable wages, up to $7,500 per household in 2026 (recently raised from the $5,000 cap that held for decades).¹ The money can come as a direct payment to your care provider or as a reimbursement to you, and it escapes federal income tax, Social Security tax, and Medicare tax when the expense qualifies and the plan meets Section 129’s rules. Two limits sit behind that headline number: your own earned income, and the interaction with the child and dependent care credit.

Which Expenses Qualify

The expense has to be for the physical care of a qualifying person, and the care has to let you (and your spouse, if you’re married) work or actively look for work.¹

Day camp counts, including camps built around a specific activity like sports or computers. Overnight camp does not, at any price. Nursery school and preschool qualify; kindergarten tuition and anything above it does not. Summer school and tutoring are out. Before- and after-school care for a child in kindergarten or higher still qualifies, because the purpose is supervision.²

Food, lodging, clothing, and entertainment are excluded even when they come bundled with real care.³ Household services like cooking, cleaning, and housekeeping can be counted if they are at least partly for the well-being of the qualifying person. A gardener, bartender, or chauffeur does not qualify.²

Who Counts as a Qualifying Individual

Two categories qualify. A dependent child under age 13 at the time care is provided. Or a spouse or other tax dependent who cannot physically or mentally care for themselves and who lives with you for more than half the year.³

The plan can’t reimburse care provided by your own child under 19, your spouse, or anyone you claim as a tax dependent. If the qualifying person is your child under 13, the child’s other parent also can’t be the paid caregiver.³

The 2026 Dollar Cap

For 2026, the annual exclusion tops out at $7,500 for a single filer or a married couple filing jointly. Married filing separately caps at $3,750 per return.¹ The cap is per household, not per child. Three kids in day care still means one $7,500 ceiling.

Anything your employer pays above the cap gets added back to Box 1 wages and is subject to income tax, Social Security tax, and Medicare tax. If you had $5,000 elected under the old limit and your open enrollment is still ahead, this is worth a look.

The Earned Income Limit

Even if your plan funds the full $7,500, the exclusion can’t exceed your earned income for the year. If you’re married, it can’t exceed the lower of your earnings or your spouse’s.¹ For a couple where one spouse works part-time, that lower number is the real ceiling.

A spouse who is a full-time student or unable to self-care is treated as earning $250 per month with one qualifying person in the household, or $500 per month with two or more.² For a full-time student with two children, that’s $6,000 in deemed annual earnings, and $6,000 becomes the effective exclusion ceiling no matter what the working spouse brings in.

Self-employed people can participate in a DCAP, and net self-employment earnings count toward earned income. But self-employed individuals can’t fund the plan through a Section 125 cafeteria plan, so the pre-tax salary reduction route that most W-2 employees use isn’t available to them.¹

Coordination With the Dependent Care Credit

The child and dependent care credit lets you claim a percentage of care expenses, up to $3,000 for one qualifying person or $6,000 for two or more. Anything you exclude through a DCAP reduces that expense pool dollar-for-dollar.³

Say you spent $10,000 on care for two children and excluded $7,500 through your DCAP. The credit calculation starts with $10,000 minus $7,500, and then the $6,000 ceiling doesn’t matter because only $2,500 is left in the pool anyway. In higher tax brackets, the DCAP exclusion usually wins, because it eliminates income tax plus payroll taxes on the excluded amount. The credit is a percentage that phases down as income rises. If your income or your care costs are on the lower side, run both.

How It Shows Up on Your W-2

Your employer reports total dependent care assistance in Box 10 of your Form W-2, whether or not it all qualifies to be excluded.⁴ Anything over the exclusion limit is also folded into Box 1 taxable wages.

You settle up on Form 2441, Child and Dependent Care Expenses. Part III of that form applies the dollar cap, the earned income limit, and the plan qualification rules to determine how much of Box 10 you actually get to exclude.⁴ Withholding doesn’t touch amounts within the exclusion; it only applies to the excess.

Use-It-or-Lose-It, and What Happens If You Leave

DCAPs funded through a cafeteria plan follow a use-it-or-lose-it rule. Unlike health FSAs, a DCAP can’t carry unused funds into the next plan year. If you don’t spend what you elected on qualifying expenses by the end of the plan year, you forfeit it.

Some employers add a grace period that gives you up to two and a half extra months after year-end to incur expenses, so a calendar-year plan with a grace period would let you spend remaining funds through March 15. Some plans also set a separate run-out period, which is the deadline for submitting claims. Neither the grace period nor the run-out is automatic; both depend on the plan document.

Because you’re guessing at future care costs when you elect, over-electing costs real money. Families with unstable care arrangements should build in some cushion below the cap.

Mid-year election changes are tightly limited. When the DCAP runs through a Section 125 cafeteria plan, your election locks at open enrollment and only a qualifying life event listed in the plan document (marriage or divorce, birth or adoption, a spouse’s job change, a dependent aging out, and similar) lets you change it. Plans don’t have to include every permitted event, so read your own document before you count on flexibility.

If you leave your job, COBRA does not apply to DCAPs. Any balance is forfeited unless you incurred the expense before your termination date and submit the claim within the plan’s run-out period. Some plans include a spend-down provision that lets a former employee keep drawing on the remaining balance for qualifying expenses through the rest of the plan year. It has to be written into the plan; if it isn’t, the balance is gone. Expenses reimbursed after termination still need to meet the work-related test, which means you or your spouse have to be gainfully employed when the expense is incurred.

What Has to Be True on the Employer’s Side

A DCAP is a separate written plan established for the exclusive benefit of employees, and the employer has to give participants a written statement each year, on or before January 31, showing what was paid or incurred in the prior calendar year.¹ Employees generally can’t be offered a straight choice between DCAP benefits and cash unless the DCAP sits inside a Section 125 cafeteria plan, which is the only structure that permits a choice between taxable and nontaxable benefits without poisoning the nontaxable side.⁵ In practice, that’s how most DCAPs are funded.

Section 129 also imposes nondiscrimination testing on eligibility, benefits, and concentration among more-than-5% owners.¹ The consequence of failure lands only on highly compensated employees, defined for 2026 as someone who earned more than $160,000 from the employer in the prior year or who owned more than 5% of the business at any point during the year.⁶ If the plan fails testing, HCEs lose the exclusion and the benefit becomes taxable to them; rank-and-file participants keep their tax-free treatment. This is worth knowing if you’re highly compensated at a small employer, because the 25% concentration limit on benefits going to more-than-5% owners is the test small plans fail most often.
