TRICARE is good coverage, but it doesn’t pay for everything. Copays at the pharmacy. Your kid’s braces. New glasses. A chiropractor. Those bills come out of your pocket with after-tax dollars—until now.
As of March 2025, active-duty service members can open a Health Care Flexible Spending Account (HCFSA) through FSAFEDS, the federal benefits program that used to be civilian-only. You set aside money before taxes, then spend it on health costs TRICARE leaves on the table. For 2026 you can stash up to $3,400, and every dollar skips federal income tax and the 7.65% FICA bite.
Here’s who qualifies, what it covers, and the rules that catch people.
What an HCFSA actually does
A Health Care FSA is a pretax bucket for medical, dental, and vision costs. The money comes out of your paycheck before taxes are calculated, which lowers your taxable income. Spend $1,000 through the account instead of out of pocket, and depending on your bracket you keep roughly $150 to $300 you’d otherwise hand to the IRS.
Your TRICARE benefit is separate. Having TRICARE doesn’t enroll you in an HCFSA, and an HCFSA doesn’t change your TRICARE coverage. The account is a tax tool that sits on top, covering what TRICARE doesn’t.
Who’s eligible
This is the part to get right, because not every uniformed member qualifies. You’re eligible for the HCFSA if you’re:
- A member of the regular (active) component
- A Reserve member on Active Guard Reserve duty under Title 10
- A National Guard member on Active Guard Reserve duty under Title 32
- A Coast Guard Reserve member on active duty for more than 180 days
If you’re a traditional drilling reservist or Guard member who isn’t on those active orders, you’re not eligible for the HCFSA right now. Regular active-duty members are—that’s the headline.
What it covers (the TRICARE gaps)
The IRS sets the eligible expense list, and it’s broad. Common ones service members actually hit:
- Copayments on prescriptions and visits
- Deductibles and copays if you’re on TRICARE Select
- Dental care and orthodontia—braces are a big one for families
- Vision—eye exams, glasses, contacts, and supplies
- Wellness care TRICARE skips: chiropractic, acupuncture, massage therapy
- Over-the-counter items: pain relievers, allergy meds, first-aid supplies, and more
If you’re on TRICARE Prime, your routine care is mostly covered, so your HCFSA tends to go toward drugstore items, dental, vision, and wellness. On TRICARE Select, you can also use it for your deductibles and copays.
The contribution numbers for 2026
- Maximum: $3,400 per person for the 2026 plan year (the IRS raised it from $3,300)
- Minimum: $100 to open an account
- Availability: the full amount you elect is available on January 1—you don’t have to wait for the payroll deductions to add up
That last point is the quiet advantage. Elect $2,000, and you can spend the whole $2,000 on January 2 even though only one paycheck’s worth has been withheld. The HCFSA fronts you the money and you pay it back over the year.
The use-it-or-lose-it rule (and the carryover that softens it)
FSAs are use-it-or-lose-it by design, but FSAFEDS gives you two cushions:
- Carryover. If you re-enroll for the next year, you can roll over up to $680 of unused money. Anything above that is forfeited.
- Claims deadline. You have until April 30 after the plan year ends to submit claims for expenses from that year.
So the move is to elect what you’ll realistically spend, not the max “just in case.” Tally a year of copays, OTC meds, a dental cleaning, and a glasses prescription—that’s a grounded number to fund.
How to enroll
You enroll at FSAFEDS.gov, not through TRICARE or finance. Two windows:
- Federal Benefits Open Season, mid-November to mid-December each year. For the 2026 plan year, it ran November 10 to December 8, 2025.
- A Qualifying Life Event—a PCS, a marriage, or the birth or adoption of a child lets you enroll outside Open Season.
Timing reality check: if you’re reading this in mid-2026, the 2026 Open Season has closed. Unless you’ve had a qualifying life event this year, your next shot is Open Season in late 2026 for the 2027 plan year. And there’s no auto-renewal—you have to re-enroll every year to keep the account and your carryover.
Don’t confuse it with the Dependent Care FSA
There’s a second account, and it’s a different animal. The Dependent Care FSA (DCFSA) has been open to active-duty members since January 1, 2024. It pays for child care, day care, and after-school or summer programs for a dependent under 13 (or an older dependent who can’t care for themselves)—not medical bills.
For 2026 the dependent-care limit jumped to $7,500 per household ($3,750 if married filing separately), up from $5,000, under the One Big Beautiful Bill Act—the first increase in nearly 40 years. One catch: unlike the HCFSA, the DCFSA has no carryover. Whatever you don’t spend by the deadline is gone, so estimate child-care costs carefully.
The bottom line
If you’re active duty and you regularly pay out of pocket for braces, glasses, copays, or drugstore health items, the HCFSA turns those into pretax dollars. The math is simple: same bills, smaller tax hit. Mark your calendar for the next Open Season, add up a realistic year of expenses, and enroll at FSAFEDS.gov.
