If you spotted “n/tax amt (f)” on a pay stub or year-end statement, it’s payroll shorthand for a non-taxable fringe benefit amount — specifically, the dependent care FSA dollars your employer set aside before tax. That same figure lands in Box 10 of your W-2, and you reconcile it at tax time on IRS Form 2441 so it stays excluded from your wages. Handle the form correctly and the money is tax-free up to the annual limit. Skip the form and the IRS can treat the whole balance as taxable income.
What the Number on Your W-2 Actually Represents
Box 10 of your W-2 shows the total dependent care benefits your employer made available to you during the year.1Internal Revenue Service. Employee Reimbursements, Form W-2, Wage Inquiries That includes the pre-tax payroll contributions you elected and any amount your employer added directly. It reflects what was made available for the plan year, not necessarily what you actually spent on care.
Because these contributions came out before tax, the Box 10 amount is not included in Box 1 (wages), Box 3 (Social Security wages), or Box 5 (Medicare wages), up to the statutory limit. If any portion goes over the limit, that excess shows up in Box 1 as taxable wages.1Internal Revenue Service. Employee Reimbursements, Form W-2, Wage Inquiries The “n/tax amt (f)” label some payroll systems use simply flags this as a non-taxable fringe benefit. The dollar figure is what matters for your return.
How Much Stays Tax-Free
For the 2026 tax year, the maximum dependent care benefit you can exclude from income is $7,500 if you file jointly or as a single parent, or $3,750 if you’re married filing separately.2Office of the Law Revision Counsel. 26 USC 129 Dependent Care Assistance Programs That’s a legislative increase from the prior cap. If you’re filing a 2025 return in early 2026, the older limits of $5,000 and $2,500 still apply to that tax year.3Internal Revenue Service. Publication 503 Child and Dependent Care Expenses
The limit is per household, not per person. If you and your spouse both have access to a dependent care FSA through separate employers, your combined contributions can’t exceed the cap. Anything reported in Box 10 above the applicable limit becomes taxable income subject to federal income tax, Social Security tax, and Medicare tax.
An example: you file jointly for 2026 and your combined Box 10 total is $8,500. The first $7,500 is excluded, and the remaining $1,000 is added to your taxable wages on your return.
The Earned Income Cap
The dollar limit isn’t the only ceiling. Your tax-free benefit also can’t exceed the earned income of either spouse. For married couples, the exclusion is capped at the lower earner’s income for the year.2Office of the Law Revision Counsel. 26 USC 129 Dependent Care Assistance Programs If one spouse earned $4,000 and the other earned $90,000, the maximum exclusion is $4,000, even though the statutory cap is higher. Single filers face the same logic: your exclusion can’t exceed your own earned income.
This catches families off guard when one spouse works part-time or takes time away from work. Contribute the full amount to your FSA but let a spouse’s earnings fall below what you set aside, and the shortfall becomes taxable. Form 2441 walks you through the calculation, and the IRS will flag a mismatch if the exclusion you claim exceeds what your income supports.
Why You Have to File Form 2441
You report dependent care benefits on Form 2441 (Child and Dependent Care Expenses), attached to your Form 1040. You must file this form if you received any dependent care benefits shown in Box 10, even when the entire amount qualifies for exclusion.4Internal Revenue Service. Instructions for Form 2441 Without it, the IRS has no way to verify your exclusion, and the full amount can be treated as taxable income.
Part III of the form is where the dependent care benefit reconciliation happens. You enter the Box 10 amount, and the form compares it against the exclusion limit and your earned income to determine how much stays tax-free. Any taxable portion flows through to Form 1040 as wages.4Internal Revenue Service. Instructions for Form 2441 The form also asks for the name, address, and taxpayer identification number of each care provider. You need that information even if your FSA reimbursed every dollar. Tax-exempt providers can be listed with “Tax-Exempt” in place of the TIN.
What the FSA Can Actually Reimburse
The exclusion only holds if the money paid for care of a qualifying person. The IRS defines a qualifying person as a child under 13 who is your dependent, a spouse who is physically or mentally unable to provide self-care and lived with you more than half the year, or another dependent unable to provide self-care who lived with you more than half the year.3Internal Revenue Service. Publication 503 Child and Dependent Care Expenses
The care itself must be work-related, meaning it enables you and your spouse (if married) to work or look for work. Day care, preschool, before- and after-school programs, and day camps all count, including specialty camps like soccer or computer camp.3Internal Revenue Service. Publication 503 Child and Dependent Care Expenses
Some common expenses do not qualify:
- Overnight camps, regardless of the child’s age
- Kindergarten tuition and above (the educational portion), though before- and after-school care for those grades does count
- Summer school and tutoring, treated as education rather than care
- Food, clothing, and entertainment, unless they’re a minor, inseparable part of the overall care cost
What Happens to Money You Didn’t Spend
Dependent care FSAs follow a strict use-it-or-lose-it rule. Money you don’t spend on qualifying expenses by the end of the plan year is forfeited back to the employer.5FSAFEDS. What Is the Use or Lose Rule Forfeiting money doesn’t create a new tax bill, because it was never included in your taxable income to begin with. But it’s still money you don’t get back.
Your employer may offer a grace period of up to two and a half months after the plan year ends to incur new qualifying expenses.6Internal Revenue Service. Eligible Employees Can Use Tax-Free Dollars for Medical Expenses If your plan year runs January through December, that extends the spending deadline to March 15 of the following year. Not every employer offers one, so check your plan documents.
A common point of confusion: dependent care FSAs cannot offer a carryover of unused funds into the next plan year.7FSAFEDS. Dependent Care FSA Carryover The carryover provision you may have seen applies only to health care FSAs, not dependent care accounts. If your benefits materials mention a carryover, confirm which account it covers.
The amount reported in Box 10 reflects the total benefits made available for the plan year, regardless of whether you forfeited any of it. Form 2441 works from that full amount when calculating your exclusion.
How It Interacts With the Child and Dependent Care Credit
The tax code won’t let you claim the same expense twice. Any dependent care costs you exclude through your FSA reduce the expenses available for the Child and Dependent Care Credit on a dollar-for-dollar basis.3Internal Revenue Service. Publication 503 Child and Dependent Care Expenses Form 2441 handles this automatically: Part III calculates your exclusion, and that amount is subtracted from the expenses you can claim in Part II.
For most families with a dependent care FSA, the pre-tax exclusion saves more than the credit would on the same dollars. But if your total qualifying expenses exceed your FSA exclusion, the excess can still count toward the credit. If you excluded $7,500 through your FSA and spent $10,000 total on qualifying care during the year, the remaining $2,500 could be applied toward the credit, subject to the credit’s own dollar limits and income phase-outs.
Divorced or Separated Parents
One boundary worth flagging: if you’re divorced or separated, only the custodial parent can use a dependent care FSA for the child’s care expenses. The custodial parent is the one with whom the child lived for the greater number of nights during the year.3Internal Revenue Service. Publication 503 Child and Dependent Care Expenses This rule applies even if the non-custodial parent claims the child as a dependent through a Form 8332 release. The FSA follows physical custody, not the dependency exemption. A non-custodial parent who contributes to a dependent care FSA for that child will find the reimbursements don’t qualify for the income exclusion, which can create an unexpected tax bill.
