FSA Limits 2026: Contribution Caps for Health and Dependent Care

FSA limits 2026 cap healthcare contributions at $3,400 per employee. The IRS announced a $100 increase over 2025 in Revenue Procedure 2025-32. Dependent care FSA 2026 stayed frozen at $5,000.

What changed for FSA in 2026 is modest on the health side and zero on the daycare side. How much can I contribute to FSA 2026 depends on which account. The health FSA just rose. The daycare cap did not budge.

Congress has not touched the dependent care FSA cap since 1986.

Health FSA Limits 2026 Rise to $3,400

The healthcare FSA limit 2026 rises to $3,400 for employees. The FSA carryover amount adjusts too, landing at $680 for plan years that begin in 2026. Employers who offer the carryover option let workers roll unused funds into the next plan year up to that cap. Everything above $680 still hits use it or lose it rules at year end.

Adjustments to these numbers come out each fall in an IRS Revenue Procedure. Revenue Procedure 2025-32 covers more than just FSAs, touching transportation benefits, adoption credits, and the foreign earned income exclusion. Plan sponsors who process payroll in house update election forms and plan documents before December 1.

The catch: the $3,400 cap is federal. Pennsylvania and New Jersey tax FSA contributions at the state level, which shrinks the real pretax benefit for workers in those states by 3.07% and up to 10.75% respectively. California and Illinois follow federal pretax treatment, so the full savings apply there.

Historical progression tells the story. The health FSA cap started at $2,500 under the Affordable Care Act in 2013 and has climbed in $50 to $150 annual increments since. The $100 bump for 2026 matches the IRS inflation-adjustment formula rather than any legislative change.

One exception matters: if your plan year runs July to June, the $3,400 cap applies only to the plan year starting in 2026. Paychecks issued in 2025 still follow last year's $3,300 cap.

For a salaried worker earning $75,000 in the 22% federal bracket, maxing the $3,400 contribution saves about $1,062 in federal tax plus $260 in FICA. The 2025 cap of $3,300 produced $1,031 plus $252 under identical math. The new ceiling adds about $39 in yearly tax savings per participant at that bracket.

Dependent Care FSA Has Not Moved Since 1986

The dependent care FSA cap stays at $5,000 for most employees and $2,500 for married filing separately. Those numbers have held since the Tax Reform Act of 1986. Inflation has cut the real value of the benefit by more than 60% over nearly four decades. Congress has proposed indexing the cap every few years, and none of those bills has passed.

Real value falls every year the cap holds.

High-income families cannot use the full $5,000 anyway. Nondiscrimination testing under Section 125 caps highly compensated employees based on what rank-and-file workers actually elect. A family earning $200,000 who elects $5,000 may see their contribution reduced after testing runs in February.

The pretax savings also depend on state income tax treatment. A family in the Bay Area paying 9.3% California state tax sees an extra $465 in annual savings on a maxed $5,000 election. A family in Texas or Florida pays no state tax, so the federal and FICA savings stand alone.

But the FSA still beats the federal child-care tax credit for most dual-earner households above roughly $43,000 in income. The credit drops to 20% of qualifying expenses at that income level. Pretax FSA contributions save 22% federal plus 7.65% FICA, which clears 29% before state tax.

The exception: two full-time earner households with income below $43,000 can still claim the $3,000 to $6,000 childcare credit on Form 2441. That credit sometimes beats the FSA for lower-income households. IRS Publication 503 provides the side-by-side comparison.

FICA Savings Turn Every FSA Dollar Into Two

Section 125 cafeteria plans let employees fund FSAs with pretax dollars. Federal income tax, state income tax, FICA, and Medicare all come off the top before the FSA deduction hits. A single worker in the 22% federal bracket who contributes $3,400 saves roughly $1,040 in combined taxes.

Employers gain from the same mechanism. FICA savings apply to the employer share too, cutting payroll tax by 7.65% on every pretax dollar routed through the cafeteria plan. For a company with 50 workers each contributing $2,000, that is roughly $7,650 in annual employer payroll tax savings.

Pretax dollars beat after-tax spending every time.

The tradeoff shows up later. Reducing FICA-taxable wages lowers future Social Security benefit accrual, which matters for workers whose top 35 earning years determine their benefit formula at retirement. For a worker earning under the Social Security wage base, every $1,000 in FSA contributions trims roughly $8 per month from their eventual retirement benefit.

Owners of S corporations with more than 2% ownership cannot participate in the cafeteria plan and lose the FICA savings on health premiums and FSA contributions. Partnerships and sole proprietors face the same exclusion under IRS rules. The workaround: employ a non-owner spouse who can participate in the plan on behalf of the family.

Scale that math across a workforce. An employer with 200 workers, half electing the full $3,400, nets roughly $26,000 in annual FICA savings before factoring in individual compensation bumps that offset lower retirement accrual.

Carryover or Grace Period: Plan Sponsors Pick One

The IRS lets plan sponsors offer one of three end-of-year options on a health FSA. Option one is the FSA carryover, now $680 for plan years beginning in 2026. Option two is a grace period of up to two and a half months after plan year end. Option three is neither, meaning strict use it or lose it rules apply on the final day of the plan year.

Most large employers pick the carryover. Smaller companies default to the grace period because the IRS sample plan language includes it out of the box. Employers cannot offer both carryover and grace period on the same FSA.

The tradeoff with carryover is narrow coverage. It only protects the first $680 of leftover funds, so an employee who contributes $3,400 and spends $2,500 still forfeits $220 at year end. The grace period protects the full balance but only for 75 days.

Worth noting, the carryover amount is indexed to inflation just like the main contribution limit. The $680 for 2026 is up from $660 in 2025. Employers must amend plan documents before each new plan year to reflect the updated carryover figure.

Timing matters for plan amendments. Plan sponsors who run a calendar-year FSA must adopt the $3,400 and $680 figures in a signed plan amendment before the first payroll of 2026. Federal rules allow retroactive amendment in limited cases, but the default is prospective only.

Qualifying Life Events Are the Only Mid-Year Escape

FSA elections lock in for the plan year. A qualifying life event is the only way to change contributions mid-year without unwinding the plan entirely.

The IRS recognizes a short list of qualifying life events: birth, adoption, marriage, divorce, a spouse's job change, and a dependent's loss of coverage. Employees have 30 days from the event date to submit paperwork to the plan administrator. Miss that window and the election stands until the next open enrollment.

No life event means no mid-year change.

However, plan administrators interpret the 30-day window differently. Federal rules allow but do not require a longer election-change window. Some third-party administrators honor paperwork filed up to 60 days after the event. Others cut off at day 30 exactly. Ask your HR team which rule your plan document uses before you need it.

The exception: dependent care FSA elections can change if a daycare provider closes, raises rates, or if a child ages out of care. Employers set the specifics in the plan document, not federal law. Documentation matters: a rate-change letter from the provider satisfies most administrators.

The Trap That Drains FSA Accounts Every December

Every December, employees race to spend down FSA balances before the deadline resets them to zero. The rush fuels a cottage industry of eligible products: prescription sunglasses, sleep aids, sunscreen, first-aid kits. Most of those purchases would never happen in June.

The real trap is not the December scramble. It is the employees who underestimate annual medical spend, elect too much, and forfeit the difference to the employer at year end.

Use it or lose it is not a law.

But the carryover does not save you on its own. Only the first $680 rolls forward. Anything above that disappears on December 31 for calendar-year plans. Worth noting, the IRS allows employers to offer a run-out period of up to 90 days after the plan year ends. This window covers receipts for expenses incurred during the plan year itself.

Miscalculating annual medical spend is the single most common FSA mistake. A worker who elects $3,400 but only incurs $1,200 in eligible expenses forfeits $2,200 to the plan sponsor at year end. Carryover recovers $680, so the net loss is $1,520 in pretax dollars the worker never sees again.

Eligible expenses are defined in IRS Publication 969, which covers health savings accounts, FSAs, and medical savings accounts. Over-the-counter medications became eligible again under the CARES Act of 2020 without a prescription. Dental, vision, and mental health copays all qualify. Menstrual care products have qualified since 2020.

Employers benefit from forfeitures. Industry data from the Employee Benefits Research Institute shows that roughly 40% of FSA participants forfeit some portion of their election each year, averaging about $370 per affected employee. Those dollars stay with the plan sponsor, subject to Section 125 rules on reuse.

Run This Check Before Open Enrollment Closes

Pull last year's medical expense receipts before you pick your 2026 number. Total the copays, prescription costs, dental work, vision, and out-of-pocket deductibles. Round down by 10% to leave room for error. That total is your realistic health FSA election.

For dependent care FSA, compare expected daycare costs against the $5,000 ceiling and your spouse's income. Married filing separately caps combined contributions at $2,500 across both returns. Form 2441 at year-end reconciles the FSA exclusion against any federal childcare credit claimed.

The tradeoff with rounding down is the forfeiture risk you accept in reverse. Underelect and you still pay tax on out-of-pocket medical costs that would have run through the FSA. The sweet spot for most workers sits between last year's actual spend and 85% of that figure.

A concrete example helps. Picture a family of one earner on a 22% federal bracket, $2,400 in predictable medical spend, $8,400 in annual daycare costs. They elect $2,100 into the health FSA and $5,000 into the daycare account. The combined tax savings clear $2,100 in the first year without any forfeiture risk.

Workers in dual-income households should share plans before enrollment day. Only one spouse can elect the $5,000 daycare cap per household, and a shared calendar of appointments and medical co-pays prevents both partners from over-electing into their own health FSA accounts. Review receipts, compare brackets, and lock in the elections together.

Plan documents do not update themselves when the IRS changes a cap.

Employers setting up a new cafeteria plan should review IRS Publication 15-B for fringe benefit rules before the first payroll deduction runs. Nondiscrimination testing, plan document language, and written election forms all have to be in place before pretax contributions start.

Compare running a cafeteria plan in house against outsourcing through a PEO that handles plan documents and Section 125 testing. Read the guide on 2026 payroll tax rates to verify that your FICA and Medicare wage bases match your payroll system.
