How to Set Your 2027 FSA Election Before the IRS Announces the Health FSA Limit
The 2027 health FSA cap is not official yet, but you can still choose a smart contribution. Here are the known limits, the carryover rule, and a worked example.

You can set your 2027 FSA election before the IRS publishes the new health FSA limit. The 2026 limit is $3,400, and your election should be based on expected expenses, not the cap. The dependent care FSA limit is already set by law at $7,500 per household for tax years beginning after 2025, or $3,750 if married filing separately.
Open enrollment is running now at many employers, and the usual IRS announcement of the next health FSA cap tends to arrive in October or November. As of October 27, 2026, we could not find an official 2027 figure. Outside estimates range from $3,450 to $3,500, and none is an IRS number. This guide shows how to pick a contribution without waiting, how the carryover rule works, and how to avoid forfeiting money you cannot get back. It is for employees with a health or dependent care FSA offered at work. Coinpurse covers saving and budgeting, and an FSA is one of the few accounts where a wrong guess can cost real money. This is general information, not tax advice.
What is the health FSA limit for 2027?
It is not official yet. The IRS publishes the annual health FSA limit in its yearly inflation-adjustment procedure, normally in October or November. The latest official figure comes from Revenue Procedure 2025-32, which sets the 2026 salary reduction limit at $3,400 and the maximum carryover amount at $680. You can read both figures in the IRS's Revenue Procedure 2025-32.
Estimates for 2027 vary. One calculator site computes $3,500 from the statutory formula, and another projects $3,450. Both are unofficial. One complication is that the Bureau of Labor Statistics did not publish October 2025 index values during the federal funding lapse, so the IRS could handle that gap in its own way. Treat any 2027 number you see online as a guess until the IRS releases it.
For planning, that uncertainty barely matters. Most people do not contribute the maximum. If you plan to elect less than $3,400, the exact cap changes nothing. If you plan to max out, check your employer's open enrollment materials, since plans sometimes publish their own ceiling or update it after the IRS announces.
What is the dependent care FSA limit?
The limit is $7,500 per household, or $3,750 for a married person filing a separate return. The statute, 26 U.S.C. § 129, says the exclusion "shall not exceed $7,500 ($3,750 in the case of a separate return by a married individual)." A 2025 law raised it from $5,000 and $2,500, effective for taxable years beginning after December 31, 2025. The text of the statute that we checked has no inflation indexing, so the figure for 2027 should match 2026. See the statute at Cornell Law's copy of 26 U.S.C. § 129.
This matters because many older web pages still show the $5,000 cap. If your payroll portal or an article lists $5,000, it is out of date. Confirm your own plan's limit, since your employer's plan document governs what you can elect.
How much should you elect?
Elect what you can predict. An FSA is a use-it-or-lose-it account, with limited exceptions, so over-electing risks forfeiting money. Under-electing leaves tax savings unused. The best approach is to build a list of expected costs for the plan year and elect close to the total.
- Pull last year's receipts or your insurer's claims summary for copays, prescriptions, dental, and vision.
- Add known costs for next year, such as braces, a planned procedure, new glasses, or a recurring prescription.
- Subtract anything you will pay with an HSA, if you have one, since the two accounts are separate.
- Round down a little, and let the carryover absorb a small surplus.
- Write the number down, then check it again after your first quarter.
Take a worked example. Suppose you expect $900 in prescriptions, $600 in dental copays, $300 for glasses, and $400 for urgent care visits, a total of $2,200. Electing $2,200 and paying with pre-tax dollars at a 22% federal marginal rate would save roughly $484 in federal income tax, ignoring payroll taxes and state taxes. That is a simplified estimate. The real figure depends on your bracket and state.
How does the carryover rule work?
Some plans let you carry unused money into the next year, up to a limit. For 2026 into 2027, the maximum carryover is $680, per the IRS's Revenue Procedure 2025-32. The 2027-to-2028 carryover will be set by the 2027 limit, and one calculator site estimates about $700, though that is a computed figure, not an official one. A plan can offer a carryover or a grace period of up to two and a half months, but not both, and plans are not required to offer either.
Ask your HR team which one your plan uses. A carryover gives you a cushion for a small leftover balance. A grace period gives you extra time to incur expenses. Neither makes it safe to over-elect by a large amount. Treat the cushion as insurance for a small miss, not a plan.
Can you have an FSA and an HSA at the same time?
Generally not, if the FSA is a general-purpose health FSA. Having one usually blocks HSA contributions for the same period. Many employers offer a limited-purpose FSA that covers dental and vision for people with an HSA. If you have a high-deductible health plan and an HSA, check which FSA your employer offers. Our guide to 2027 HSA limits and open enrollment contributions explains how to set that account. The two can work together if the FSA is limited-purpose, but verify with your plan.
Dependent care FSAs are separate from both. They cover care that allows you and a spouse to work, such as day care or summer day camp. Plan rules and IRS tests apply, so check eligibility before you rely on it. If you are also thinking about children's savings accounts, our comparison of Trump accounts and 529 plans covers that decision.
What can you spend FSA money on?
A health FSA covers qualified medical costs, such as copays, deductibles, prescriptions, dental work, vision exams, and glasses. Over-the-counter medicines and menstrual products became eligible under a 2020 law, but your plan administrator keeps the list you must follow. Cosmetic procedures and general wellness items usually do not qualify, so check before you buy.
Keep receipts or the itemized statement for every claim, since your administrator may ask for proof. Many plans give you a debit card that pays at the register. Even if you use the card, hold on to the paperwork. An unverified charge can be reversed, and you will have to repay it.
Plan big expenses early. If you know you need dental work or new glasses, schedule them in the first half of the year, so you use the money before the final months and avoid a year-end rush.
What if your expenses change mid-year?
Most FSA elections are locked for the year. Exceptions apply for qualifying life events, such as marriage, birth or adoption, a change in a spouse's job, or a change in coverage, and your employer's plan sets the details. If you have a life event, ask HR how soon you must request a change.
If you are sitting on a balance late in the year, make a list of eligible purchases you have delayed, such as a dental cleaning, a vision exam, or replacement glasses. Check your plan's list of eligible items, and confirm the deadline for claims. Some plans allow a run-out period after year end to submit receipts, which differs from the period to spend money. Mark both dates on your calendar.
How does an FSA fit with your other saving goals?
An FSA is a spending account, not a savings account. Contributions come out of your paycheck, so they reduce your take-home pay. Make sure your emergency fund can cover that reduction. Our guide on adjusting your 2027 401(k) contributions shows how to balance pre-tax deductions across several accounts.
Put all of your pre-tax deductions in one table: 401(k), HSA or FSA, commuter benefits, and insurance premiums. Check what your paycheck looks like after each deduction. At Coinpurse, we suggest changing one number at a time, so you can see its effect before you commit.
Conclusion
You do not need the IRS's 2027 figure to make a smart FSA election. Base your health FSA contribution on a list of expected costs, use the carryover as a small buffer, and treat the dependent care limit of $7,500 as settled. Skip any article that still shows a $5,000 cap.
This week, gather last year's receipts, add known costs for next year, and write down a number. Then check your plan's rules on carryover and grace periods before enrollment closes.
