Federal Retirement Healthcare Costs 2026: What FEHB Really Costs After You Leave

FEHB premiums jumped 12.3% in 2026. That's roughly twice the rate of overall inflation. And here's the part nobody tells you at your pre-retirement seminar: even though the government still covers about 72% of your premium after you retire, your costs go up anyway.

Why? Because you lose the pre-tax deduction. As an active employee, your FEHB premiums come out before taxes. In retirement, they come out of your annuity after taxes. Same government contribution percentage, higher effective cost.

That's just the starting point. Between FEHB premiums, Medicare Part B, dental, vision, and out-of-pocket expenses, most federal retirees spend $9,000 to $15,000 per year on healthcare. If you haven't budgeted for that number, you're not alone. Most federal employees haven't.

Key Takeaways

• FEHB premiums increased 12.3% in 2026, and retirees pay their share with after-tax dollars (a hidden cost increase)
• Budget $9,000 to $15,000+ per year for total healthcare costs in retirement
• The FEHB 5-year rule is permanent: if you break enrollment, you lose FEHB in retirement forever
• Medicare Part B costs $202.90/month in 2026, and IRMAA surcharges can add $81 to $487/month for higher-income retirees
• TSP withdrawals count toward IRMAA income thresholds, so large withdrawals can trigger surprise Medicare surcharges
• Use the FEHB Calculator to compare plan costs before your next Open Season

What FEHB Costs in Retirement (2026 Numbers)

The government contribution formula doesn't change when you retire. OPM continues paying approximately 72-75% of your FEHB premium, up to a set dollar cap.

Here are the 2026 maximum government contributions:

Coverage Level	Max Government Share (Biweekly)	Annual Value
Self Only	$324.76	~$8,444
Self Plus One	$711.17	~$18,490
Self and Family	$778.03	~$20,229

That's a significant benefit that continues for life, as long as you meet the 5-year rule (more on that below).

Your share depends on which plan you choose. In 2026, Basic Option plans saw the steepest increases at 16-18%, while Standard Option plans increased 7-8%. After the government contribution, most retirees pay $3,600 to $6,000 per year for FEHB alone.

The Hidden Cost: Post-Tax Premiums

This is the part that blindsides people.

As an active employee, your FEHB premiums are deducted pre-tax. That's a meaningful tax benefit. If you're in the 22% tax bracket and paying $400/month in premiums, you're effectively saving $88/month in taxes.

In retirement, your premiums are deducted from your annuity after taxes. Same premium, but now it costs you 20-30% more in real dollars because you've lost the tax advantage.

Example: A GS-13 retiree paying $5,000/year in FEHB premiums as an active employee (pre-tax) would need roughly $6,250 in pre-tax retirement income to cover that same $5,000 premium after taxes. Over a 25-year retirement, that tax difference alone adds up to more than $30,000.

Nobody puts this on the retirement checklist. But it should be line one.

Medicare Part B: The $2,435 Annual Add-On

Most federal retirees should enroll in Medicare Part B at age 65, even with FEHB coverage. Here's why:

When Medicare is your primary insurer and FEHB is secondary, your out-of-pocket costs drop significantly. Medicare covers 80% of approved charges first, then FEHB picks up most or all of the remaining 20%. Without Medicare, FEHB is your only coverage, and you'll hit deductibles and copays much faster.

The 2026 Medicare Part B premium is $202.90 per month ($2,435/year). Some FEHB plans offer partial rebates on Part B premiums, which can reduce this cost.

Don't delay enrollment. If you miss the initial enrollment window at 65 and don't have qualifying employer coverage, you face a permanent 10% penalty for every 12-month period you could have enrolled but didn't. That penalty never goes away.

IRMAA: The Medicare Surcharge That Catches High-Income Retirees

If your modified adjusted gross income (MAGI) exceeds certain thresholds, Medicare charges an extra monthly surcharge called IRMAA (Income-Related Monthly Adjustment Amount).

IRMAA works like a cliff. Earn $1 over the threshold and you're in the next bracket.

2026 IRMAA thresholds (single filers):

MAGI	Part B Surcharge	Monthly Total
Below $109,000	None	$202.90
$109,001 to $136,000	+$81.20	$284.10
$136,001 to $170,000	+$202.90	$405.80
$170,001 to $500,000	+$324.70	$527.60
Above $500,000	+$487.00	$689.90

For married filing jointly, double those income thresholds.

The TSP trap: Here's what catches federal retirees off guard. IRMAA is calculated on your MAGI from two years prior. A large TSP withdrawal in 2024 could spike your 2026 IRMAA. If you took a $200,000 TSP distribution to buy a house, you might be paying an extra $325/month in Medicare premiums two years later.

Planning TSP withdrawals around IRMAA thresholds can save thousands. This is especially important in the years right around retirement when you might be rolling over or consolidating TSP funds.

The FEHB 5-Year Rule: Break It and Lose Coverage Forever

This is the most important enrollment rule in federal benefits, and it's surprisingly easy to break by accident.

The rule: To carry FEHB into retirement, you must be continuously enrolled for at least 5 years immediately before your retirement date (or since your first opportunity to enroll, if less than 5 years).

What counts toward the 5 years:

• Being the primary FEHB policyholder
• Being covered as a dependent on your spouse's FEHB plan
• Any combination of the above

What breaks the 5-year clock:

• Voluntarily canceling your FEHB enrollment during a period of continuous employment
• Letting coverage lapse without re-enrolling during the next Open Season

The permanent consequence: If you don't meet the 5-year requirement at retirement, you cannot carry FEHB into retirement. Period. There is no appeal, no exception, no late enrollment. You lose access to the government's 72-75% premium contribution for the rest of your life.

Deferred retirees beware: If you leave federal service and defer your annuity (collecting it years later), you cannot keep FEHB in retirement. The 5-year rule requires continuous enrollment up to the retirement date, and deferred retirees have a gap.

If you're within 5 years of retirement, confirm your FEHB enrollment status with your HR office now. Don't assume.

FEDVIP: The Dental and Vision Coverage Most Retirees Forget

Standard FEHB plans don't include dental or vision coverage. That's what FEDVIP (Federal Employees Dental and Vision Insurance Program) is for.

Good news: FEDVIP has no 5-year rule. If you're enrolled as an active employee, coverage automatically continues into retirement.

Bad news: If you're not enrolled in FEDVIP before retirement, you can't add it later. This is a permanent gap.

Without FEDVIP, expect to pay $1,500 to $3,000 per year out-of-pocket for dental and vision care. Two cleanings, a crown, and a pair of glasses add up fast.

If you're not currently enrolled in FEDVIP dental and vision, sign up during the next Federal Benefits Open Season. It's cheap insurance against a permanent coverage gap.

What Federal Retirees Actually Spend on Healthcare

Here's a realistic annual healthcare budget for a federal retiree age 65+ with both FEHB and Medicare:

Expense	Annual Cost
FEHB premium (your share)	$3,600 to $6,000
Medicare Part B	$2,435
FEDVIP dental	$600 to $1,200
FEDVIP vision	$200 to $400
Out-of-pocket (copays, deductibles)	$2,000 to $5,000
Total	$9,000 to $15,000+

If your income triggers IRMAA surcharges, add $1,000 to $5,800 per year.

And remember: healthcare costs typically increase 5-7% annually, roughly double the rate of general inflation. A $12,000 healthcare budget at age 62 could be $24,000 by age 76 if costs compound at 6% per year. Your FERS pension COLA (if you retire before 62, you don't get COLA until 62) won't keep pace with healthcare inflation.

Build a healthcare reserve. Don't plan for flat costs.

Compare Your FEHB Plan Costs Now

If you haven't compared FEHB plans recently, you might be overpaying. Plan designs, premiums, and provider networks change every year, and the 12.3% average increase in 2026 hit some plans harder than others.

Use our free FEHB Calculator to compare premiums across plans for your coverage level. Small differences in monthly premiums compound into thousands over a 20-30 year retirement.

If you're modeling your full retirement income picture, the FERS Retirement Calculator shows your projected monthly annuity. Subtract your estimated healthcare costs to see what you'll actually have left to spend.

5 Things to Do Before You Retire

1. Confirm your FEHB 5-year status. Check with HR that you've been continuously enrolled for 5+ years. If you're close to the line, do not cancel for any reason.

2. Enroll in FEDVIP dental and vision. If you're not enrolled, sign up during Open Season. Coverage carries into retirement automatically.

3. Model your post-tax healthcare costs. Take your current FEHB premium, remove the pre-tax benefit, add Medicare Part B ($202.90/month in 2026), and add estimated out-of-pocket costs. That's your real retirement healthcare budget.

4. Plan TSP withdrawals around IRMAA. If you're near the $109,000 (single) or $218,000 (married) threshold, spreading TSP withdrawals across multiple years can avoid IRMAA surcharges.

5. Review your FEHB plan every Open Season. Don't default to last year's plan. Premium increases, provider changes, and new plan options make annual comparison worth the 30 minutes.

Frequently Asked Questions

How much does FEHB cost federal retirees in 2026?

A typical federal retiree pays $3,600 to $6,000 per year in FEHB premiums after the government contribution (which covers about 72-75%). Add Medicare Part B at $2,435/year, plus dental, vision, and out-of-pocket costs, and total healthcare spending runs $9,000 to $15,000+ annually.

Does the government still pay for FEHB after I retire?

Yes. The government continues paying approximately 72-75% of your FEHB premium in retirement. However, your share is deducted from your annuity with after-tax dollars, unlike the pre-tax deductions you had as an active employee. This tax difference makes your effective cost higher in retirement.

What is the FEHB 5-year rule?

To carry FEHB into retirement, you must be continuously enrolled in FEHB for at least 5 years immediately before retirement, or since your first opportunity to enroll if you've been eligible less than 5 years. If you let your enrollment lapse, you lose FEHB eligibility in retirement permanently.

Do I need Medicare if I have FEHB?

Medicare Part A is free for most retirees and enrolling is strongly recommended. Medicare Part B costs $202.90/month in 2026 but significantly reduces your out-of-pocket costs when coordinated with FEHB. Delaying Part B enrollment past 65 triggers permanent late penalties unless you have qualifying employer coverage.

What is IRMAA and how does it affect federal retirees?

IRMAA is a surcharge on Medicare Part B premiums for higher-income retirees. In 2026, if your modified adjusted gross income exceeds $109,000 (single) or $218,000 (married filing jointly), you pay $81 to $487 extra per month on top of the standard Part B premium. TSP withdrawals count toward this income threshold.
