Open Enrollment Checklist for Working Professionals: Your 2027 Benefits Guide

By Uzma Mazhar | 5 min read

Open enrollment takes about an hour of your time, and the choices you make in that hour follow every paycheck for the next 12 months. That matters more this year. Workers with employer family coverage now pay an average of $7,471 a year toward premiums, up 9% from 2025, according to KFF's 2026 Employer Health Benefits Survey. This open enrollment checklist walks you through each decision in plain language, so you can finish with confidence instead of clicking "keep my current plan" and hoping for the best.

The short answer: An open enrollment checklist is a short list of steps to finish before your benefits deadline. Confirm your dates, review last year's costs, compare plans by total yearly cost, set your HSA or FSA amounts, update dependents and beneficiaries, and save your confirmation. It takes about an hour and can save you money all year.

Key takeaways

• Put your deadline on your calendar first. Employer dates vary, and the federal Marketplace runs November 1 to January 15.
• Compare plans by total cost (premiums plus what you would pay out of pocket), not by premium alone.
• For 2027, the HSA limit rises to $4,500 for self-only coverage and $9,000 for family coverage, up from $4,400 and $8,750 in 2026.
• The 2027 health FSA limit has not been announced yet. It is projected at about $3,500, up from $3,400 in 2026.
• The dependent care FSA limit is $7,500 per household for 2026 and is expected to stay at $7,500 in 2027, a meaningful help for working parents.
• Missed the window? Marriage, a new baby or losing other coverage usually opens a 30-day special enrollment window at work.

When Is Open Enrollment for 2027 Coverage?

Your employer sets its own open enrollment window, and many run for only a few weeks in the fall. Look for an email from HR or a notice in your benefits portal, and put the closing date on your calendar today.

If you buy your own coverage through the federal Health Insurance Marketplace, HealthCare.gov lists these dates:

• November 1: Open Enrollment starts for 2027 plans.
• December 15: Last day to enroll or change plans for coverage that starts January 1.
• January 15: Open Enrollment ends. Plans chosen between December 16 and January 15 start February 1.

Some states run their own marketplaces with different deadlines, so check your state's site if you don't use HealthCare.gov.

What Should You Review Before You Pick a Plan?

A few minutes of homework makes every later step easier. Before you open the enrollment portal, gather:

• Last year's health costs. Look at your insurer's claims summary or your pharmacy receipts. Note how many doctor visits, prescriptions and specialist appointments you had.
• Your must-keep doctors and medications. Check that they are in-network and covered in each plan you're considering. Networks and drug lists can change from year to year.
• Changes coming in 2027. A wedding, a baby, a move, a child aging off your plan, or a planned surgery can all change which plan makes sense.
• Your spouse's or partner's options. If you both have workplace coverage, compare both plans side by side before you decide who covers whom.

How Do You Compare Health Plans by Total Cost?

The plan with the lowest premium is not always the cheapest. Start with a simple formula for each plan:

Yearly premiums + expected out-of-pocket costs = your real yearly cost

Your out-of-pocket costs include the deductible, copays and coinsurance. Each plan also has an out-of-pocket maximum, the most you would pay for covered care in a year. That number is your worst-case budget, so read it closely.

Deductibles are a real line item for most workers. KFF found that the average single-coverage deductible for workers in plans with a general deductible is $1,955 in 2026.

Here is an illustrative example, not a real plan:

• Plan A: lower premium, higher deductible. Usually a good fit if you rarely see a doctor and have savings to cover a surprise bill.
• Plan B: higher premium, lower deductible. Often a better fit if you expect regular care, ongoing prescriptions or a planned procedure.

Run both a "quiet year" and a "busy year" through the formula. Pick the plan you could live with in either case.

How Much Can You Put in an HSA or FSA in 2027?

Tax-advantaged accounts let you pay for care with pre-tax dollars. The limits change most years, so use this year's numbers, not last year's.

HSA limits for 2027 (official)

You can contribute to a health savings account (HSA) only if you're enrolled in a qualifying high-deductible health plan (HDHP). The IRS has set the 2027 figures in IRS Revenue Procedure 2026-24. The 2026 figures come from IRS Revenue Procedure 2025-19.

The last two rows are rules for the health plan itself, not limits on what you put in. Your plan's deductible and out-of-pocket maximum have to fall within them for you to use an HSA. IRS Publication 969 also notes that an HSA is portable, so it stays with you if you change employers.

FSA limits for 2027 (health FSA figures projected)

The IRS has not announced the 2027 health FSA limit yet. It usually releases it in October or November, so it could come out any day. Until then, the 2027 health FSA figures below are projections, so confirm the final number in your enrollment portal.

Health flexible spending account (FSA). The 2026 health FSA limit and carryover come from IRS Revenue Procedure 2025-32. FSAs are generally "use it or lose it." A plan may offer either a grace period of up to 2½ months or a carryover, but not both, so estimate carefully.

Dependent care FSA. The limit went up from $5,000 to $7,500 per household starting in 2026 under a new federal law, according to IRS Publication 15-B. It's a fixed dollar amount that isn't adjusted for inflation, so it should stay at $7,500 in 2027. If you're married and file separately, it's $3,750 each. If you pay for child or dependent care so you can work, this account can lower your taxable income.

Can you have an HSA and an FSA? You generally can't contribute to a regular health FSA and an HSA in the same year. If you want both, ask your employer whether it offers a "limited-purpose" FSA, which covers only dental and vision costs and works alongside an HSA.

Which Other Benefits Deserve a Second Look?

Health insurance gets the spotlight, but a few other elections are easy to forget:

• Retirement savings. The 2026 401(k) employee deferral limit is $24,500, per the IRS retirement plan limits page. The IRS had not posted 2027 limits when this guide was written. At a minimum, contribute enough to get any employer match.
• Life and disability insurance. Check whether your employer's basic coverage is enough for your household, and what extra coverage costs through payroll.
• Beneficiaries. Update them on life insurance and retirement accounts after any marriage, divorce or new child.
• Family-friendly benefits. Look for parental leave, fertility, caregiving or backup child care benefits. They are often listed outside the medical plan section.
• Dental and vision. Compare what each plan covers against the care you expect to need.

What If Your Life Changes After Open Enrollment?

You are not locked in no matter what. Under federal HIPAA rules, the U.S. Department of Labor explains that marriage, birth, adoption, placement for adoption or losing other coverage gives you special enrollment rights in your workplace plan. You must request enrollment within 30 days of the event.

For Marketplace plans, HealthCare.gov's Special Enrollment Period page generally gives you 60 days after a qualifying life event to pick a plan. Act either way quickly, and keep documents such as a marriage certificate or a letter showing your old coverage ended.

Your Step-by-Step Open Enrollment Checklist

Save or print this list and check off each item:

• Find your enrollment deadline and add a reminder two days before it.
• Pull last year's claims and pharmacy costs.
• List your doctors and prescriptions, then confirm they are covered.
• Note any life changes expected in 2027.
• Compare at least two plans using premiums plus expected out-of-pocket costs.
• Check each plan's out-of-pocket maximum and confirm you could cover it.
• Set your HSA, health FSA or dependent care FSA amount.
• Review your 401(k) contribution and employer match.
• Update dependents and beneficiaries.
• Submit your choices, then save or screenshot the confirmation page.
• Check your first 2027 paycheck to make sure deductions match your choices.

What Open Enrollment Mistakes Should You Avoid?

Most open enrollment regrets come from a few small, avoidable slips, so watch for these as you make your choices.

• Auto-renewing without looking. Premiums, networks and drug coverage change. A quick review protects you.
• Choosing on premium alone. A low premium with a high deductible can cost more in a busy health year.
• Overfunding an FSA. Base your amount on costs you can predict, such as prescriptions and planned visits.
• Forgetting your dependents. Make sure everyone you want covered is listed, with correct birth dates.
• Waiting until the last day. Portals slow down and HR questions take time. Aim to finish a few days early.

FAQs

What should be on an open enrollment checklist?

Your deadline, last year's health costs, your doctors and prescriptions, and any life changes you expect. Then compare plans by total cost, set your HSA or FSA contributions, and update dependents and beneficiaries. Finish by saving your confirmation page.

When is open enrollment for 2027 health coverage?

Workplace plans set their own dates, so check with HR. For the federal Marketplace, HealthCare.gov lists November 1, 2026, to January 15, 2027. Enroll by December 15 if you want coverage to start January 1.

What is the HSA contribution limit for 2027?

The IRS set the 2027 HSA limit at $4,500 for self-only coverage and $9,000 for family coverage, up from $4,400 and $8,750 in 2026 (IRS Revenue Procedure 2026-24). People 55 and older can add a $1,000 catch-up contribution. You must be enrolled in a qualifying high-deductible health plan, with a deductible of at least $1,750 (self-only) or $3,500 (family) in 2027, to contribute.

Can I change my benefits after open enrollment ends?

Usually only after a qualifying life event. For workplace plans, the Department of Labor says you must request special enrollment within 30 days of events like marriage, birth, adoption or losing other coverage. Marketplace plans generally allow 60 days.

Is a high-deductible health plan a good choice for me?

It can be if you're generally healthy, can cover the deductible from savings, and want to use an HSA. If you expect regular care or ongoing prescriptions, a lower-deductible plan may cost less over the year. Compare both using premiums plus expected out-of-pocket costs. If you choose an HSA plan, you generally can't also put money in a regular health FSA, but a limited-purpose FSA for dental and vision costs works alongside an HSA.
