Most people pick a health plan on the monthly cost. The number that protects your family is the one you hope you never see, which is the most you can be made to pay in a really bad year. On TRICARE that number is small. For a retiree family in Group A on TRICARE Prime it's $3,000 for all of 2026, however bad the year gets.
Under the Affordable Care Act, a civilian family plan, from the marketplace or an employer, can legally charge that same family up to $21,200 for in-network care in 2026 and $24,000 in 2027. That's before premiums. A civilian family carries that risk. You don't, as long as you keep TRICARE, and it's one of the most valuable things your retirement gives you.
2026 catastrophic caps for retiree families
- Group A, TRICARE Prime $3,000
- Group A, TRICARE Select $4,381
- Group B, Prime or Select $4,635
- TRICARE For Life $3,000
Each is the most a whole family pays in a calendar year for covered care, and the enrollment fee counts toward it (TRICARE).

How the Catastrophic Cap Works
The catastrophic cap is the most your family pays for TRICARE-covered care in a calendar year. It's one number for the whole family, not one per person. It runs January 1 to December 31 and resets to $0 every January 1 (TRICARE). Once you reach it, TRICARE pays your share of covered care for the rest of the year, and if you're in Prime or Select you stop paying the enrollment fee too.
These count toward the cap.
- Your TRICARE Prime or Select enrollment fee
- Deductibles
- Copays and cost-shares for covered care, inpatient and outpatient
- Pharmacy copays
These don't.
- Care TRICARE doesn't cover
- Point-of-service charges, which is what Prime charges when you see someone without a referral
- The extra a non-participating provider can bill you, up to 15% above TRICARE's allowed amount
- Premiums for Reserve Select, Retired Reserve, Young Adult and the Continued Health Care Benefit Program
- Extended Care Health Option costs
The fee rule is a bigger deal than it sounds. On most civilian plans the premium sits on top of the out-of-pocket maximum. On TRICARE Prime and Select, the enrollment fee is inside the cap. A Group A family on Prime pays a $765 fee, and that $765 is part of the $3,000, not added to it.
One more detail that helps in a retirement year. Whatever your family paid toward the active duty cap earlier in the year carries over to the retiree cap. TRICARE's own example is a Group B family that already met the $1,324 active duty cap, which then has $3,311 left to reach the $4,635 retiree cap (TRICARE).
Every 2026 Cap by Group
You're in Group A if your sponsor first enlisted or was appointed before January 1, 2018, and Group B if it was on or after that date. Almost everyone retiring now is Group A. These are the official 2026 figures (TRICARE, 2026 Costs and Fees).
| Who you are | Group A | Group B |
|---|---|---|
| Retiree family, TRICARE Prime | $3,000 | $4,635 |
| Retiree family, TRICARE Select | $4,381 | $4,635 |
| Medically retired or survivor of an active duty death, Prime or Select | $3,000 | $4,635 |
| Active duty family, Prime or Select | $1,000 | $1,324 |
| TRICARE For Life | $3,000 | |
| TRICARE Reserve Select | $1,324 | |
| TRICARE Retired Reserve | $4,635 | |
| TRICARE Young Adult | $1,324 with an active duty or Reserve Select sponsor, $4,635 with a retired sponsor | |
A family split between plans has a combined limit. If some of a Group A family is on Prime and some on Select, the Prime members stop paying at $3,000 and the Select members keep paying until the family reaches $4,381 (TRICARE).
How the Law Sets the Cap and Raises It
Some caps are written into the law as a flat dollar amount and never move. Others start from a base and rise every year with the retired pay COLA.
The fixed caps
- $1,000 for Group A active duty families in 10 U.S.C. 1079(b)(5) since 1987.
- $3,000 for Group A retiree families in 10 U.S.C. 1086(b)(4), applied to Prime by 32 CFR 199.17. The same $3,000 covers TRICARE For Life, and Group A medically retired members and survivors on either plan.
The $3,000 has a history. When Congress set the retiree cap in 1987 it was $10,000. The 1993 defense bill cut it to $7,500 on October 1, 1992, and the 2001 defense bill cut it to $3,000 on October 30, 2000 (32 CFR 199.4(f)(10)). It hasn't moved since. A fixed cap shrinks in real terms every year, so the $3,000 a Group A Prime family faces today is worth a good deal less than the $3,000 of 2000.
The caps that rise with the COLA
The 2017 defense bill created Group B and set its caps at $3,500 for retiree families and $1,000 for active duty families starting in 2018. It also gave Group A retirees on Select a $3,500 cap starting in 2021 (10 U.S.C. 1075 and 1075a). Each of those rises every year by the same percentage as retired pay, rounded down to the dollar, with anything under a dollar carried into the next year.
Here's the Group B retiree cap worked forward from its $3,500 base with each year's retired pay COLA (SSA COLA history). It lands exactly on TRICARE's published 2026 caps.
| Year | COLA applied | Group B retiree cap | Group A Select cap |
|---|---|---|---|
| 2018 | Base | $3,500 | Not yet in effect |
| 2019 | 2.8% | $3,598 | Not yet in effect |
| 2020 | 1.6% | $3,655 | Not yet in effect |
| 2021 | 1.3% | $3,703 | $3,500 (base) |
| 2022 | 5.9% | $3,921 | $3,706 |
| 2023 | 8.7% | $4,262 | $4,028 |
| 2024 | 3.2% | $4,399 | $4,157 |
| 2025 | 2.5% | $4,509 | $4,261 |
| 2026 | 2.8% | $4,635 | $4,381 |
The COLA in each row is the one that took effect the December before. The 2027 caps follow the same rule with the 3.6% COLA that took effect December 1. TRICARE hadn't posted them as of November 2, 2026, and DoD's September notice says they'll be on tricare.mil/changes before open season starts. I'll add them here when they post. The fixed $1,000 and $3,000 caps won't change.
What a Civilian Plan Can Make You Pay
Civilian plans have an out-of-pocket maximum too, and federal law sets the highest one a plan can use. For in-network care in 2026 it's $10,600 for one person and $21,200 for a family. For 2027 it rises to $12,000 and $24,000, about 13.2% in one year (CMS). The same limit binds employer group plans, not just the marketplace, except older plans grandfathered in from before the law (42 U.S.C. 300gg-6, 18011). Out-of-network care has no legal ceiling at all. A high deductible plan that qualifies for an HSA has its own ceiling of $17,000 for a family in 2026 and $17,400 in 2027 (IRS, IRS).
| The most a family can pay for covered care | 2026 | 2027 |
|---|---|---|
| TRICARE Prime, Group A retiree | $3,000 | $3,000 |
| TRICARE For Life | $3,000 | $3,000 |
| TRICARE Select, Group A retiree | $4,381 | Rises with the COLA, not posted yet |
| TRICARE Prime or Select, Group B retiree | $4,635 | Rises with the COLA, not posted yet |
| HSA-qualified high deductible plan (legal limit) | $17,000 | $17,400 |
| Marketplace or employer plan, in-network (legal limit) | $21,200 | $24,000 |
| Original Medicare with no supplement | No limit | No limit |
Put side by side, a Group A Prime family's worst year is $18,200 smaller than the legal limit on a civilian family plan in 2026. For a Group B family it's $16,565 smaller. And the civilian figure doesn't include premiums, while TRICARE's does include the enrollment fee.
To be fair, plenty of employer plans set their limit well under the legal maximum. KFF's survey of employers found that for single coverage in 2026, 14% of workers are in a plan with an out-of-pocket maximum of $2,000 or less and 24% are in one above $6,000 (KFF 2026 Employer Health Benefits Survey). So check the plan documents for the real number. The legal limit is the ceiling, not the typical plan. But the ceiling keeps climbing faster than TRICARE's. From 2026 to 2027 the civilian limit goes up 13.2%, while the TRICARE caps that move at all go up with a 3.6% COLA.
A bad year comes faster than people expect. The average stay in a U.S. community hospital cost the hospital about $16,700 in 2022, and that's their cost, not the bill (AHRQ). One stay with a coinsurance plan can put a family well into its out-of-pocket maximum. On TRICARE Prime a Group A retiree pays $198 for that admission.
Know Your Number Before You Look at Offers
Because you keep TRICARE, a job doesn't have to be the thing that protects your family's health costs. That changes what a job has to pay you. The free calculator works out the salary that matches your retired life, with your pension, your VA pay and your state's tax already counted.
Run My Numbers Free →Taking a Civilian Job With Health Insurance
Taking a job doesn't cost you TRICARE. You stay eligible, and you can use it alone or keep it next to a job's plan. The gap between TRICARE's cap and a civilian plan's only lands on you if you give TRICARE up. Three rules decide how a job's plan fits with it.
TRICARE pays last
By law TRICARE pays after any other health insurance you have, including an employer plan (TRICARE, 32 CFR 199.8). The employer plan processes the claim first, and then you or your doctor file with TRICARE. If the other plan denied a claim because its rules weren't followed, TRICARE may deny it too. Keeping TRICARE behind a job's plan can cover what that plan leaves, but you still pay the TRICARE enrollment fee to keep it.
TRICARE blocks an HSA
If a job offers a high deductible plan with a health savings account, being covered by TRICARE means you can't put money in the HSA. The IRS says it plainly. "[A]n individual covered under TRICARE is not an eligible individual and may not contribute to an HSA" (IRS Notice 2004-50). So if you plan to use an HSA, you'd have to drop TRICARE, and with it the $3,000 to $4,635 cap.
Compare worst years, not premiums
If you're deciding whether a job's plan is worth signing up for, compare like with like. The premium is real money. In 2026 the average worker paid $7,471 a year toward a family plan, on a total premium of $28,303 (KFF 2026 Employer Health Benefits Survey). The job plan's worst year is its family out-of-pocket maximum plus your share of its premium. TRICARE's worst year is your cap, $3,000 to $4,635 with the enrollment fee already inside it. Run both numbers before you sign up.
At 65, TRICARE For Life and Medicare
At 65 most retirees move to TRICARE For Life, which wraps around Medicare. You need Medicare Part A and Part B, and you pay the Part B premium. The standard premium is $202.90 a month in 2026, and it's higher at higher incomes (TRICARE, Federal Register). TRICARE For Life charges no enrollment fee, and its cap is $3,000 per family.
Original Medicare by itself has no yearly limit on what you pay (Medicare.gov). In 2026 the Part A hospital deductible is $1,736 for each benefit period, and there's no limit to how many benefit periods you can have in a year. Medicare.gov says that stays true unless you add supplemental coverage like Medigap or join a Medicare Advantage plan. TRICARE For Life does that job for you, with the same $3,000 limit.
Frequently Asked Questions
What is the TRICARE catastrophic cap for retirees in 2026?
For a retiree family in Group A it's $3,000 a year on TRICARE Prime and $4,381 on TRICARE Select. For Group B it's $4,635 on either plan. TRICARE For Life is $3,000. Group A is a sponsor who first enlisted or was appointed before January 1, 2018.
Does the TRICARE enrollment fee count toward the catastrophic cap?
Yes. Enrollment fees, deductibles, copays, cost-shares and pharmacy copays all count toward the cap, and once you reach it you stop paying the TRICARE Prime or Select enrollment fee for the rest of the year. Premiums for Reserve Select, Retired Reserve and Young Adult don't count.
Is the TRICARE catastrophic cap per person or per family?
Per family. It's one limit for everyone in the family on the plan, and it runs on the calendar year, resetting to $0 every January 1.
What are the TRICARE catastrophic caps for 2027?
TRICARE hadn't posted them as of November 2, 2026. The Group A Prime retiree cap of $3,000, the TRICARE For Life cap of $3,000 and the Group A active duty family cap of $1,000 are fixed and won't change. The Group A Select and Group B caps rise by the 3.6% retired pay COLA, rounded down to the dollar.
How does the TRICARE cap compare with a civilian out-of-pocket maximum?
The legal limit for a family on most marketplace and employer plans is $21,200 for in-network care in 2026 and $24,000 in 2027, before premiums. A Group A retiree family on TRICARE Prime pays no more than $3,000, with the enrollment fee included, so its worst year is $18,200 smaller in 2026.
Can I contribute to an HSA if I have TRICARE?
No. IRS Notice 2004-50 says someone covered by TRICARE isn't an eligible individual and can't contribute to a health savings account, even if they're also on a high deductible plan.
