In 2025, more than 96,000 of you took the We’re in This Together (WITT) pledge to learn more about your benefits. You stayed informed through monthly texts and emails with helpful articles, podcasts and videos on topics such as:

  • Improving your nutrition and gut health through WeightWatchers and Cylinder
  • Supporting your mental health with free counseling sessions through Resources for Living®
  • Growing your money habits through SmartDollar® financial coaching and your T. Rowe Price retirement plan
  • Preparing for a new addition to your family with Unum’s bonding leave
  • And so much more

This is a powerful reminder of how much you care — not just about your work, but about your health and your future.

You also told us in the WITT pledge survey how much you loved hearing from each other. So, we increased our WITT podcasts from quarterly to monthly — 13 episodes this year! Each one featured real voices, real stories and real support from Costco employees.

Thanks for showing up, lifting each other up and continuing to grow. We’re in this together — and we’re grateful for every one of you.

Beat the cold & flu season with your benefits

The holidays are a time for celebrations. But winter can also bring sniffles, stress and seasonal illnesses. Colds, the flu and other viruses spread more easily this time of year — especially indoors and in close gatherings.

Here are some ways to protect your health and enjoy the season:

  • Drink water — Aim for 8 cups a day to stay hydrated and support your immune system.
  • Wash your hands often — Especially before eating or touching your face.
  • Stick to your sleep routine — Rest helps your body fight off germs.
  • Take breaks from stress — Quiet time with loved ones can boost your mood and well-being.
  • Get your flu shot — It’s your best defense and can reduce symptoms if you get sick.
  • Open a window — Fresh air helps reduce the spread of airborne viruses.

Your Costco benefits are here to support you — so you can focus on what matters most this season.

If you or a family member feels sick, use the 98point6® app to talk to a doctor in minutes — no appointment needed, no copay required. You can get care, prescriptions and advice without leaving home.

Here’s a reimbursement accounts overview

Health Care Reimbursement Account (HCRA)
Dependent Care Assistance Plan (DCAP)
What it’s for
Out-of-pocket health care expenses for you, your spouse and eligible dependents — Copays, deductibles and coinsurance, plus dental, vision, hearing aid and pharmacy expenses.
Dependent care expenses for you and your spouse — Eligible elder or childcare costs so you and your spouse can work.

It can’t be used for dependent health care costs — that’s the HCRA.
2026 contribution limits
$120 up to $3,400
Up to $7,500 (or $3,750 if married and filing separately)
When funds are available
Your full annual election amount is available January 1.
Funds are available as they’re deducted from your paycheck.
How reimbursement works
Autopay — Your HCRA is set to automatically reimburse you for eligible copays, deductibles or coinsurance for medical, dental and vision expenses.

If you plan to use your funds for things like braces, be sure to turn off autopay at the start of the year on the Inspira website or app.

Debit card — Use it at a Costco Pharmacy, Costco Optical Department, Costco Hearing Aid Center and at the Costco Online Pharmacy.

Inspira website or app — You can submit a claim for reimbursement when you have an eligible expense.
Inspira website or app — You can submit a claim for reimbursement when you have an eligible expense.

You’ll be reimbursed up to the current balance in your account.
When to enroll
Enroll during Annual Enrollment.
Enroll during Annual Enrollment or during the year as your childcare needs change.
Election changes
Election changes are not allowed — so you won’t be able to start, stop or change your contributions after Annual Enrollment.
Start, change or stop your contributions as your qualifying childcare needs change.
Rollover
Unused funds that carry over to the next year (total amount is determined by the IRS each year)
Remaining balance of up to $660 automatically rolls over from 2025 to 2026.
No rollover
Grace period
When you can use leftover funds to pay for new expenses
No grace period
Use funds leftover at the end of the year on expenses during the grace period (January 1–March 15 of the following year).
Claim filing deadline
Last day to file claims for the previous year’s expenses
April 30 of the following year
April 30 of the following year
HCRA and DCAP funds are USE IT OR LOSE IT!

This means you forfeit any money left in your account after the claim filing deadline of April 30 of the following year. (Except for your HCRA rollover up to the IRS rollover maximum.)

Not sure how much to contribute?

If you usually meet your annual deductible, you could start with that amount. You won’t pay taxes on what you put in. HCRA funds can help cover your out-of-pockets costs for doctors’ visits, X-rays, lab work and more, while DCAP funds can pay for in-home aid and daycare.

Keep in mind that both HCRA and DCAP funds are “use it or lose it,” though a portion may roll over to the next year.

Autopay uses your HCRA funds automatically, unless you turn it off. You can adjust your contribution during Annual Enrollment each year. DCAP funds are a little different — you can change your contribution amount throughout the year, and you need to submit a claim for reimbursement. While you can enroll or make changes to your DCAP contribution amount during Annual Enrollment, you can also do so if your child- or eldercare needs change.

Can’t sleep? Try Sleepio

That can make it harder to fall asleep — and stay asleep — night after night. This can take a toll on your body and mind, putting you at risk for mental health issues, obesity, diabetes and heart disease. Your new free benefit Sleepio can help.

4 tips for more zzzzzzs

  1. Eat healthy. A varied diet with plenty of vitamins, minerals and antioxidants makes a major contribution to your immune system, overall health – and sleep. Dietitians recommend 3-5 servings of different fruits and vegetables each day.
  2. Power down. Avoid cell phones, TVs and computers in the hour or two before bedtime. Limit caffeine to the start of your day.
  3. Establish a bedtime routine. Take a warm shower or bath. Listen to calming music. Having a routine helps condition your mind and body for sleep.
  4. Protect your time and energy. Trying to do too much or be everything to everyone can cause stress and anxiety and affect your sleep. Set boundaries if you’re over-extended and make time to unwind and do the things you enjoy.

What’s a gut microbiome?

Your gut microbiome is the community of “good” and “bad” bacteria that live inside your stomach and intestines. They help you digest food, fight off germs and maintain a healthy weight. If your body doesn’t have enough good bacteria, bad bacteria can thrive, causing a range of health issues:

Catch conditions early when they’re easier to treat

Skin cancer and breast cancer are the two most common cancers among Costco employees. More than 6,000 employees and their family members are dealing with skin cancer. Nearly 1,800 have been diagnosed with breast cancer. Find out how you can catch these conditions early, when treatment is most effective.

The power of preventive care

Preventive services such as annual physical exams and mammograms are powerful weapons in fighting these cancers. A recent study shows that regular mammograms reduce the risk of dying from breast cancer by 50%.1 Only 21% of Costco employees and family members get all of their recommended preventive services each year. Are you up to date on your preventive care?

Routine preventive care helps you stay ahead of illness and disease so you can be your best. Preventive care includes services such as your annual physical, certain blood tests, cancer screenings and vaccines, even dental cleanings and vision exams. This kind of care helps you and your doctor know how you’re doing. Most importantly, it can catch a health condition in its earliest stages, when it’s easier to treat.

How to find a PCP

Employees and their family members enrolled in a Costco medical plan can find an in-network primary care provider by visiting Costcobenefits.com and clicking “Find a Doctor” under Health & Wellness. 

Mainland employees can learn more about how to find the PCP that’s right for them in this Aetna ID card update:

Aetna ID card update for mainland employees

To make it easier for you and your family members enrolled in an Aetna medical plan to access preventive care, your new Aetna ID card will have a PCP listed for you and each family member.

Here are a few other things to know: 

  • Your plan hasn’t changed. It’s not an HMO. You are not required to see the PCP on your ID card and your plan doesn’t require a referral to see a specialist.
  • Your PCP was carefully selected. If you’ve seen a PCP in the last two years, we’ve added the most recent PCP or practice name to your card.
  • If you haven’t, we looked for PCPs accepting new patients within 25 miles who have met the Aetna Smart Compare® high standards for care.
  • You can change your PCP at any time, and as many times as you need, by calling your Aetna Health Concierge* at 800-814-3543 (TTY: 711).
  • If you change your PCP, we’ll send you a new card. Your digital ID card will be available on your Aetna member website the next day.
  • Note: If you see a physician’s assistant (PA) or nurse practitioner (NP), you may see the supervising physician’s name or the practice name on your card.

Your PCP is your partner in good health

Your primary care physician (PCP) is your first stop for preventive care. They can give you your annual physical and order blood work, tests and screenings.

Here are some recommended preventive services. Your age, gender, and family and personal medical histories can make a difference in which services you need and when to start them. Ask your doctor what’s right for you.

Don’t forget about dental and vision exams

Learn more about what regular dental care can do for you here.

It’s important to get an annual eye exam, even if you have perfect 20/20 vision. Eye exams can help catch brain tumors, cancer, heart disease and more. In 2024, over 100,000 Costco employees and family members got their annual eye exam. Nearly 3,400 discovered a condition they didn’t know about, giving them the opportunity to seek care. The most common conditions were:

  • High blood pressure or cholesterol
  • Diabetes
  • Cataracts
  • Glaucoma

Employees and their family members enrolled in a Costco medical plan are automatically enrolled in vision coverage.

The plan will pay:

  • Up to $80 for your annual refractive eye exam
  • $175 toward the purchase of prescribed eyewear every year (you don’t have to spend it all at once)

You also get $1,750 toward the purchase of prescribed medically necessary hearing aids every four years.

Protect your health by quitting tobacco or nicotine for good

If you use tobacco and/or nicotine, think about making this your year to quit. The Costco Tobacco & Nicotine Cessation Program can provide the support you need with a plan personalized for you. You’ve got so much to gain once you stop smoking, using tobacco or vaping, including: 

  • A lower risk for heart attack and certain cancers
  • Improved blood flow
  • Better lung function
  • A lower risk for gum disease, tooth loss, dry eye syndrome and cataracts

And that’s just a start. Imagine climbing stairs or playing with the kids and not being out of breath. Even food tastes better! Visit Costcobenefits.com and click “Quit Tobacco” under Health & Wellness to start your journey to quitting for good.
