2026 FSA Savings Calculator (Healthcare, DCFSA $7,500 & LPFSA)

What is an FSA? IRS Section 125 Cafeteria Plans Explained

A Flexible Spending Account (FSA) is a special savings account offered through your employer that lets you set aside a portion of your paycheck before taxes to pay for qualified out-of-pocket healthcare or dependent care expenses. The money comes out of your gross pay before federal income tax, state income tax, and FICA taxes (Social Security and Medicare) are calculated — which means every dollar you put into an FSA costs you less than a dollar from your regular take-home pay.

Here is a simple way to think about it. Without an FSA, you earn money, pay taxes on it, and then use what is left to pay your doctor bills. With an FSA, you pay your doctor bills first (through payroll deductions), and the government only taxes what is left. That ordering change is where your savings come from.

FSAs are employer-sponsored benefits. You cannot open one on your own through a bank or brokerage. Your employer must offer an FSA as part of its benefits package, and you elect to participate during your company’s open enrollment period (typically October through November for a January 1 plan year start). Key eligibility points:

• You must be a W-2 employee. Self-employed individuals and 1099 contractors are not eligible for FSAs (but may qualify for HSAs or self-employed health deductions).
• Both full-time and part-time employees can participate, as long as the employer’s plan allows it.
• You can have an FSA even if you are covered under a spouse’s health insurance plan — the FSA is tied to your employer, not your health plan.
• There is no income limit to participate. Whether you earn $30,000 or $300,000, you can elect an FSA.

The 3 Types of Flexible Spending Arrangements (FSA)

The IRS recognizes three distinct types of FSAs, each designed for a different category of expenses. Understanding which ones apply to your situation is the first step toward maximizing your tax savings.

Healthcare FSA (Qualified Medical Expenses)

This is the most common type. A Healthcare FSA covers qualified medical, dental, and vision expenses that your health insurance does not fully pay. Think of it as a tax-free wallet for copays, deductibles, prescriptions, glasses, dental fillings, and hundreds of other IRS-approved health costs. The 2026 contribution limit is $3,400 per employee (up from $3,300 in 2025). You do not need to be enrolled in any specific health plan to use a Healthcare FSA — it works alongside any employer-sponsored insurance.

Dependent Care FSA (Daycare & DCFSA)

A DCFSA helps you pay for the care of children under age 13, or a disabled spouse or dependent, so that you (and your spouse, if married) can work or attend school. Qualifying expenses include daycare, preschool, before-and-after-school programs, summer day camps, and elder care for qualifying dependents. The 2026 contribution limit is $7,500 per household thanks to H.R.1 (the “One Big Beautiful Bill Act”) — a historic increase from the $5,000 cap that had been frozen since 1986.

Limited-Purpose FSA (Dental, Vision & HSA Compatibility)

An LPFSA is a specialized version of the Healthcare FSA that covers only dental and vision expenses. It exists for one specific reason: to allow employees enrolled in a High-Deductible Health Plan (HDHP) with a Health Savings Account (HSA) to still benefit from an FSA without disqualifying their HSA. A regular Healthcare FSA would disqualify your HSA, but an LPFSA does not — because it is “limited” to dental and vision. The 2026 limit is $3,400, same as the Healthcare FSA.

Official 2026 IRS FSA Contribution Limits & Carryover Caps

The IRS adjusts FSA contribution limits annually based on inflation (measured by the Chained Consumer Price Index, or C-CPI-U). For 2026, the limits were published in Revenue Procedure 2025-19. The most significant change, however, came from Congress — the H.R.1 DCFSA increase is not an inflation adjustment but a legislative change.

The Healthcare FSA limit is a per-employee cap. If both spouses work for employers offering FSAs, each spouse can contribute up to $3,400 to their own Healthcare FSA, for a household total of $6,800 in pre-tax healthcare savings. The DCFSA limit, however, is a per-household cap — married couples share the $7,500 limit regardless of how many employers offer the benefit.

How FSA Tax Savings Work: Federal, State & FICA Reductions

FSA contributions are deducted from your paycheck before three different taxes are calculated. This “triple tax advantage” is what makes FSAs so powerful — and it is the same pre-tax treatment that 401(k) contributions receive, but for healthcare expenses. Let us walk through the three layers.

Your FSA contribution reduces your federal taxable income. If you are in the 22% marginal tax bracket and you contribute $3,400 to a Healthcare FSA, you save $748 in federal income tax ($3,400 × 22%). The higher your bracket, the more you save — someone in the 32% bracket saves $1,088 on the same election.

In most states, FSA contributions are also exempt from state income tax. If your state tax rate is 5%, that is an additional $170 saved on a $3,400 election. Eight states have no income tax (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming) — residents of those states skip this layer but still benefit from the other two.

This is the savings layer that most people — and most competing calculators — miss entirely. FSA payroll deductions reduce your Social Security and Medicare taxable wages. That saves you an additional 7.65% on every dollar contributed (6.2% Social Security + 1.45% Medicare). On a $3,400 Healthcare FSA, the FICA savings alone total $260.10.

That $1,178 means you are effectively getting a 34.65% discount on every medical expense you pay through your FSA. A $200 doctor visit only costs you $131 in real take-home pay. A $500 pair of prescription glasses costs you $327. The savings are automatic — you do not need to itemize deductions on your tax return or file any special forms.

The Hidden 7.65% FICA Tax Advantage (Social Security & Medicare)

If you have ever looked at another FSA calculator online, you probably noticed they show you federal and state tax savings — then stop. Our calculator includes FICA savings because those are real dollars that stay in your pocket. Let us break down exactly what FICA is and how FSAs interact with it.

FICA stands for the Federal Insurance Contributions Act. It is the payroll tax that funds Social Security and Medicare. In 2026, the rates are:

• Social Security: 6.2% on wages up to the taxable wage base of $176,100. Your employer also pays 6.2% (for a combined 12.4%). Earnings above $176,100 are exempt from Social Security tax.
• Medicare: 1.45% on all wages — there is no cap. Your employer matches another 1.45%. If you earn above $200,000 (single) or $250,000 (married filing jointly), you pay an additional 0.9% Medicare surtax.
• Combined employee rate: 7.65% on wages up to $176,100, and 1.45% on wages above that threshold. FSA deductions reduce your wages before FICA is calculated, saving you up to 7.65%.

This is a fair question. Since FSA contributions lower your Social Security taxable wages, they could theoretically reduce your future Social Security benefit. In practice, the impact is negligible. Social Security benefits are calculated based on your highest 35 years of earnings, and the reduction from a $3,400 FSA election is so small (approximately $2–$4 per month in future benefits) that the immediate $260 per year in FICA savings is a significantly better deal, especially when you invest that savings in a retirement account.

IRS Publication 502: Eligible FSA Medical Expenses

The IRS defines eligible FSA expenses in Publication 502. The list is broader than most people realize — especially after the CARES Act of 2020 made over-the-counter (OTC) medications and menstrual care products eligible without a prescription. Here is a practical breakdown.

• Doctor & specialist copays — Primary care, specialists, urgent care, telemedicine visits, annual physicals
• Prescription medications — Any drug requiring a prescription, including insulin (insulin is FSA-eligible even without a prescription since 2020)
• Over-the-counter medications — Tylenol, Advil, Allegra, Claritin, Pepto-Bismol, cold medicines, acid reducers — no prescription needed since the CARES Act
• Dental care — Cleanings, fillings, crowns, root canals, dentures, orthodontics (braces and Invisalign)
• Vision care — Eye exams, prescription glasses, contact lenses, lens solution, LASIK, PRK surgery
• Medical devices — Blood pressure monitors, glucose meters, CPAP machines, hearing aids, crutches, bandages
• Mental health — Psychiatrist/psychologist visits, therapy copays, substance abuse treatment
• Preventive items — Sunscreen (SPF 15+), first aid kits, thermometers, COVID tests, PPE
• Women’s health — Menstrual products (pads, tampons, cups), breast pumps, prenatal vitamins, fertility treatments
• Alternative medicine — Acupuncture, chiropractic care (if medically necessary)

• Health insurance premiums — You cannot use FSA funds to pay monthly insurance premiums
• Cosmetic procedures — Teeth whitening, cosmetic surgery, hair transplants (unless medically necessary)
• Gym memberships & fitness equipment — Even with a doctor’s note, these are generally not covered
• Vitamins & supplements — General health vitamins are not eligible unless prescribed to treat a specific condition
• Toiletries — Toothpaste, deodorant, shampoo, and general hygiene products

Plan Deadlines: The $680 Rollover vs. 2.5-Month Grace Period

The biggest fear employees have about FSAs is the “use it or lose it” rule — and it is a legitimate concern. Unlike HSAs (which roll over indefinitely), FSAs have restrictions on carrying unused funds to the next year. Your employer chooses one of three options for its plan. Understanding which one applies to you is critical for setting your election amount.

Under the rollover option, you can carry up to $680 of unused Healthcare FSA funds into the next plan year. Any amount above $680 is forfeited. This is the most common option and offers the best safety net. The rollover cap is indexed to inflation annually — it was $640 in 2024, $660 in 2025, and $680 in 2026.

Some employers offer a grace period instead of a rollover. This gives you an additional 2 months and 15 days after the plan year ends (typically until March 15) to spend any remaining balance. After the grace period expires, unused funds are forfeited. This is useful if you have predictable expenses in early Q1 — schedule that dental cleaning or eye exam before March 15.

In the strictest scenario, any unused funds at the end of the plan year (December 31 for most employers) are permanently forfeited. There is no rollover and no grace period. If your employer uses this option, you need to be extremely conservative with your election and aim to use every dollar before year-end.

If you find yourself approaching December with unused FSA funds, there are legitimate ways to spend down your balance before the deadline:

• Stock up on FSA-eligible OTC items — sunscreen, first aid supplies, contact lens solution, allergy medications, pain relievers
• Buy a new pair of prescription glasses or sunglasses — even if your current pair is fine, a backup is always useful
• Schedule dental work you have been postponing — cleanings, fillings, or that crown your dentist recommended
• Book a telemedicine appointment — copays count, and you might address a health concern you have been ignoring

The Historic H.R.1 $7,500 DCFSA Limit (Dependent Care)

The Dependent Care FSA received its first contribution limit increase in approximately 40 years when H.R.1 — the “One Big Beautiful Bill Act” — permanently raised the cap from $5,000 to $7,500 per household, effective January 1, 2026. This is not an inflation adjustment (the DCFSA was never indexed to inflation) — it is a one-time legislative increase passed by Congress.

The DCFSA reimburses expenses for the care of a qualifying individual so that you (and your spouse, if married) can work, look for work, or attend school full-time. Qualifying individuals include:

• Children under age 13 who are your dependents — daycare, preschool, pre-K, before-and-after-school care, and summer day camps (not overnight camps)
• A disabled spouse or dependent of any age who lives with you and is physically or mentally incapable of self-care
• A disabled dependent parent who lives with you and cannot care for themselves

DCFSA vs. Form 2441 Dependent Care Tax Credit (DCTC)

This is one of the most confusing aspects of dependent care tax planning. The IRS offers two tax benefits for childcare expenses, and you cannot use both for the same dollars. Any expenses reimbursed through your DCFSA reduce the amount you can claim for the Dependent Care Tax Credit (DCTC) on IRS Form 2441. Choosing the wrong one can cost your family hundreds of dollars.

The DCTC gives you a tax credit (not a deduction) equal to 20% to 35% of qualifying expenses, depending on your Adjusted Gross Income (AGI). The maximum eligible expenses are $3,000 for one child or $6,000 for two or more children.

• AGI under $15,000: 35% credit rate → max credit $1,050 (1 child) or $2,100 (2+ children)
• AGI $15,000–$43,000: Credit rate declines from 35% to 20% (decreases by 1% for each $2,000 of AGI above $15,000)
• AGI above $43,000: 20% credit rate → max credit $600 (1 child) or $1,200 (2+ children)

For households with an AGI above approximately $43,000, the DCFSA almost always provides greater savings. At the 22% federal bracket + 5% state + 7.65% FICA, a $7,500 DCFSA election saves $2,599 — compared to a maximum DCTC of $1,200 for two or more children. The DCFSA wins by $1,399.

Lower-income families with AGI below $25,000–$30,000 may benefit more from the DCTC because the credit rate is 27%–35% and the credit directly reduces your tax bill dollar-for-dollar. Also, if you have very low childcare costs (under $3,000 per year), the DCTC may be simpler and sufficient. Our calculator Tab 2 compares both options automatically based on your specific income and family size.

The Dual Account Strategy: LPFSA + High Deductible Health Plan (HSA)

If you are enrolled in a High-Deductible Health Plan (HDHP) and contribute to a Health Savings Account (HSA), you might think you cannot also have an FSA. You are partially right — you cannot have a general Healthcare FSA and an HSA at the same time. But you can have a Limited-Purpose FSA (LPFSA) alongside your HSA. This combination unlocks the highest possible pre-tax healthcare savings allowed by the IRS.

The idea is simple: use your LPFSA to cover all dental and vision expenses (cleanings, fillings, glasses, contacts, eye exams) and reserve your HSA for medical expenses and long-term savings. Since HSA funds roll over indefinitely and can be invested, every dollar you divert from your HSA to an LPFSA for dental and vision expenses is a dollar that stays invested in your HSA for the future.

FSA vs. HSA vs. HRA — Complete Comparison

These three account types are often confused because they all help you pay for medical expenses with tax advantages. But they differ dramatically in eligibility, ownership, portability, and long-term value. Here is the definitive comparison for 2026.

Seven Common FSA Mistakes and How to Avoid Them

Even experienced employees make errors with their FSA elections. These mistakes can cost hundreds of dollars in lost savings or forfeited funds. Here are the seven most common ones we see, and how to avoid each.

Many employees choose a tiny FSA amount ($500–$1,000) because they are afraid of losing money under the use-it-or-lose-it rule. But under-electing means you are paying full after-tax prices for all the medical expenses above your election. If you spend $2,500 per year on healthcare but only elect $1,000, you miss out on approximately $520 in tax savings (at the 34.65% effective rate). The rollover cap of $680 gives you a significant buffer — use it.

Most people only calculate their federal and state tax savings when deciding their FSA election amount. By ignoring the 7.65% FICA savings, they underestimate the true benefit by approximately 22% (7.65 ÷ 34.65). Our calculator includes FICA automatically, giving you the full picture.

If your household AGI is below $30,000, the Dependent Care Tax Credit might save you more than a DCFSA. Always run both scenarios — our calculator Tab 2 does this comparison automatically. The difference can be $200–$400 for lower-income families.

FSA elections are made during open enrollment (typically October–November). If you miss the deadline, you cannot enroll until the next plan year unless you experience a qualifying life event (marriage, divorce, birth of a child, loss of spouse’s coverage, or a change in employment status). Set a calendar reminder for two weeks before your company’s enrollment deadline.

A surprising number of employees simply forget about their remaining FSA balance until it is too late. Set a reminder for November 1 to check your balance and plan your spending. Most FSA administrators have mobile apps that show your real-time balance — download yours and check it monthly.

Most FSA plans now come with a debit card that you can swipe at pharmacies, doctor’s offices, and vision centers. Using the card eliminates the need to submit manual reimbursement claims and creates an automatic paper trail for IRS documentation. If you pay out of pocket and forget to submit a claim, that expense goes unreimbursed — and you have effectively overfunded your FSA.

A general-purpose Healthcare FSA disqualifies you from contributing to an HSA. If you are enrolled in an HDHP and want to max out your HSA, you must use a Limited-Purpose FSA (LPFSA) instead. If you accidentally enroll in both a Healthcare FSA and an HSA, you will need to correct the error before tax filing or face penalties. The only exception is the LPFSA, which is compatible with HSAs because it is limited to dental and vision expenses only.
