A birth qualifies as an event that lets a parent open or increase a Dependent Care Flexible Spending Account mid-year, and for 2026 the pre-tax limit is $7,500 for most households, up from $5,000, under the One Big Beautiful Bill Act.

Alicia’s son was born on a Tuesday, and by Friday her company’s benefits portal was already asking her to confirm an election worth up to $7,500 a year, tax-free, that nothing in the hospital’s discharge folder or her new-parent paperwork had mentioned by name.

The moment to act

Under Treasury Regulation 1.125-4, a rule published in the Code of Federal Regulations (CFR), a birth is one of the specific events that lets you change a Dependent Care Flexible Spending Account (FSA) election in the middle of the plan year instead of waiting for the next open enrollment (26 CFR 1.125-4 lists birth under its “Number of dependents” category of qualifying events). No federal law sets an exact number of days to make the change. Your employer’s own plan document does. Most plans give 30 days, but nothing in the regulation requires that specific number, so the one deadline that actually matters is whatever your plan document says, not the number a coworker or a benefits website quotes you.

Call your Human Resources (HR) department today and ask for two things in writing: the exact date your election window closes, and the exact date paid child care needs to start before any money comes back to you. That second date matters more than most parents realize, and it’s covered below.

The account most new parents never hear about

A Dependent Care Flexible Spending Account (FSA) lets you set aside part of your paycheck before taxes are calculated, then reimburses you as you pay for child care that lets you and your spouse work. The Internal Revenue Code (IRC) has capped how much of your pay can go into that account since 1986 at $5,000 for a joint or single filer, $2,500 if married filing separately. That number stayed put through 2025, apart from one temporary COVID-relief exception: a one-year bump to $10,500 for 2021 only, which expired and reverted to $5,000 the following year.

That changed under the One Big Beautiful Bill Act (OBBBA), a 2025 federal tax law that raised the limit to $7,500 ($3,750 if married filing separately), effective for tax years beginning after December 31, 2025, which means it applies starting with 2026 (26 U.S.C. 129 shows the amended figure directly in the statute). It’s the first permanent increase to this specific limit in 40 years.

Filing status	2025 and earlier	2026 and after (OBBBA)
Joint, single, or head of household	$5,000	$7,500
Married filing separately	$2,500	$3,750

A separate benefit, the Child and Dependent Care Tax Credit, exists too, but it isn’t a second pot of the same money. The Internal Revenue Code caps the credit’s qualifying expenses at $3,000 for one child or $6,000 for two or more, then reduces that cap dollar for dollar by whatever you already excluded through the FSA (26 U.S.C. 21). Run $7,500 through the FSA with two kids and there’s nothing left of the $6,000 credit cap to claim on top of it.

What $7,500 pre-tax is actually worth

Say Alicia and her husband file jointly, sit in the 22% federal tax bracket, and both work. If they elect the full $7,500 through her Dependent Care FSA, the math looks like this: $7,500 multiplied by 22% federal income tax equals $1,650 avoided. $7,500 multiplied by 7.65% Federal Insurance Contributions Act (FICA) payroll tax equals $573.75 avoided. Total tax savings: $2,223.75. Their $7,500 in child care effectively costs them $5,276.25 out of pocket.

If they skipped the FSA and claimed the Child and Dependent Care Tax Credit instead, the number is smaller. With two qualifying children, the credit only counts up to $6,000 of expenses, at a rate of 20% for a household at their income level: $6,000 multiplied by 20% equals $1,200.

Same family, same child care bills: the FSA is worth $2,223.75 in savings, and the credit alone tops out at $1,200. The FSA wins for this household by more than $1,000, mostly because it also dodges payroll tax, which the credit never touches.

The mistake that forfeits real money

Dependent Care FSAs follow a strict use-it-or-lose-it rule. Money left in the account at the end of the plan year is forfeited, and unlike some health FSAs, there’s no rollover of a few hundred dollars into next year for this account (the Internal Revenue Service’s own carryover guidance is written for health FSAs specifically and doesn’t mention dependent care at all). Some plans allow a grace period of up to two and a half extra months to spend down a balance, but that’s a plan design choice, not a guarantee.

Here’s the trap that catches new parents specifically: the FSA only reimburses “employment-related expenses,” meaning care that’s actually happening and that lets you work. A newborn who isn’t yet in any paid arrangement, because a parent is still on leave or a relative is watching the baby for free, hasn’t generated a reimbursable expense yet, even though the election itself started the day the baby arrived. Electing the full $7,500 the week your child is born, before you know exactly when paid care will start, can mean months of payroll deductions piling up against expenses that don’t exist yet. Estimate conservatively based on when care actually begins, not the maximum the law allows.

What to do at 30, 60, and 90 days

1. Within your plan’s own window (commonly, but not always, 30 days): confirm the election shows up correctly on your next pay stub, and get the exact date claims can start in writing from HR.
2. Around 60 days: if paid child care still hasn’t started, ask whether your plan allows a second election change to lower the amount, rather than letting deductions build up toward a balance you may not spend.
3. By 90 days and beyond: start logging every paid-care receipt against your plan’s own claim-filing deadline, which is set by the plan document, not the Internal Revenue Service, so nothing goes unclaimed when the year closes.

This account runs alongside, not instead of, the 30-day window most new parents already know about for health coverage, and it’s separate from the other newborn paperwork deadlines that land in the same first month. If you’re also weighing unpaid time off against your budget, the first 30 days of unpaid parental leave carries its own set of benefit deadlines worth reading alongside this one.

Frequently asked questions

Do I have to wait for my company’s open enrollment to start a Dependent Care FSA? No. A birth is a recognized event under federal tax rules that lets you open or change this election mid-year, without waiting months for your employer’s next open enrollment period. Contact HR right away, since your own plan sets the deadline to act.

What if my plan gives me 60 days instead of 30? That’s normal. No federal rule sets a specific number of days for this election change. Your plan document controls the deadline, and it varies by employer, so get the exact date in writing rather than assuming any particular number applies to you.

Can I use the FSA and the Child and Dependent Care Tax Credit in the same year? You can use both, but not on the same dollars. Whatever you contribute to the FSA reduces the credit’s expense cap by that same amount, so a family that maxes out the FSA on two kids has nothing left of the $6,000 credit cap to claim separately that year.

What happens to money I don’t use by the end of the year? It’s forfeited under the use-it-or-lose-it rule, unless your plan offers a grace period of up to two and a half extra months to spend it. There’s no year-to-year rollover for this specific account the way some health FSAs allow.

Does the $7,500 limit apply if I’m married filing separately? No. The 2026 limit for married couples filing separately is $3,750, exactly half of the $7,500 joint limit, under the same federal law that raised both figures this year.
