Yes, you can retire while on medical leave, provided you meet your employer’s age and service requirements for retirement. Your leave status doesn’t block you from submitting a retirement notice. The harder question is whether retiring right now is the right financial move, because the timing affects Social Security, health insurance, pension vesting, and the tax hit on any retirement account you touch. Getting the sequence right can be worth tens of thousands of dollars.
Look at Social Security Disability First
This is where people leaving work for medical reasons most often lose money. If your condition is severe enough to keep you from working, you may qualify for Social Security Disability Insurance, and SSDI usually pays substantially more than claiming Social Security retirement early.
For anyone born in 1960 or later, full retirement age is 67. Claiming Social Security retirement at 62 permanently reduces your monthly payment by 30%.1Social Security Administration. Retirement Age and Benefit Reduction That reduction never goes away. SSDI pays the equivalent of your full retirement benefit regardless of your age when payments start, and at full retirement age it automatically converts to retirement benefits at the same amount.2Social Security Administration. What You Need to Know When You Get Social Security Disability Benefits
The gap is real. Someone entitled to $2,000 per month at full retirement age would receive only $1,400 by claiming early at 62. On SSDI, that same person would receive $2,000. Over 20 years, that’s $144,000. SSDI also triggers Medicare eligibility after 24 months of benefits, which matters if you’re years away from 65.3Centers for Medicare & Medicaid Services. Original Medicare (Part A and B) Eligibility and Enrollment
The catch: SSDI approval takes time and isn’t guaranteed. Many initial applications are denied. You can apply for both SSDI and early retirement simultaneously as a safety net, but if the disability claim fails, you’re locked into the reduced retirement benefit permanently.4Social Security Administration. If I Get Social Security Disability Benefits and I Reach Full Retirement Age, What Happens? If your condition could plausibly meet the Social Security Administration’s definition of total disability, talk to a disability attorney before you file for early retirement.
Check Your Pension and 401(k) Vesting Before You Sign Anything
Being on leave doesn’t disqualify you from retiring. If your plan lets you retire at 60 with 20 years of service and you meet both, you’re eligible whether you’re at your desk or on medical leave. What you need to confirm is where your leave leaves you on vesting and benefit accrual.
Federal regulations protect you from losing ground during FMLA leave. Unpaid FMLA leave cannot be treated as a break in service for pension vesting or eligibility. If your plan requires you to be employed on a specific date to receive credit for a year of service, you’re treated as employed on that date while on FMLA leave.5eCFR. 29 CFR 825.215 – Equivalent Position Your employer doesn’t have to count unpaid FMLA time toward benefit accrual, though, so the vesting clock keeps running even if the benefit itself doesn’t grow. Leave that runs past the 12 FMLA weeks gets no such guarantee; whether it counts is up to your plan’s terms.
Federal law also sets minimum vesting standards for employer contributions to retirement plans. Most defined contribution plans like 401(k)s use one of two schedules:6Office of the Law Revision Counsel. 26 USC 411 – Minimum Vesting Standards
- Three-year cliff vesting: 0% of employer contributions until you complete three years of service, then 100%.
- Two-to-six-year graded vesting: 20% after two years, 40% after three, 60% after four, 80% after five, 100% after six.
Your own contributions are always fully vested. But if you’re close to a milestone, retiring a few months early can cost you a meaningful chunk of employer-matched funds. Ask your benefits department for your summary plan description and your current vesting percentage before you commit to a date.
The Tax Rules That Change if You’re Under 59½
Retirement plan distributions trigger income tax, and if you’re under 59½, there’s usually an additional 10% early withdrawal penalty.7Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Several exceptions matter for someone retiring from medical leave.
The Rule of 55
If you leave your job during or after the calendar year you turn 55, you can take distributions from that employer’s 401(k) or 403(b) without the 10% penalty. Public safety employees like firefighters, EMTs, and law enforcement qualify starting at 50.7Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Important detail: this exception applies only to the plan held with the employer you’re separating from. Roll those funds into an IRA and you lose the penalty-free access until 59½. If you’ll need to draw from that money before then, leave it in the employer plan.
Disability and Medical Expenses
If the Social Security Administration has determined you are totally and permanently disabled, early distributions are penalty-free at any age. A separate exception covers unreimbursed medical expenses above 7.5% of your adjusted gross income. Distributions for health insurance premiums while unemployed also qualify if you received unemployment compensation for at least 12 weeks.7Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions These waive the penalty only. Regular income tax still applies.
Rollovers
When you retire, you can move your 401(k) balance into an IRA or another employer’s plan. A direct rollover, where funds transfer without passing through your hands, avoids the mandatory 20% withholding that applies when a check is made payable to you. If you receive the distribution directly and want to complete the rollover yourself, you have 60 days to deposit the full amount into a qualifying account. Miss that window and the entire distribution becomes taxable income for the year.8Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
Health Coverage After You Retire
Losing employer-sponsored health coverage is the most immediate practical problem, especially when you’re already dealing with a medical condition. Your options depend on your age.
COBRA
Retirement is a qualifying event under COBRA for employers with 20 or more employees. You can continue your employer’s group health plan for up to 18 months, but you pay the full cost — up to 102% of the total premium.9U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Workers The sticker shock is real. If your employer covered 75% of an $1,800 monthly family premium and you were paying $450, COBRA would run about $1,836.
If the Social Security Administration has determined that you or a covered family member is disabled at the time of the qualifying event or within the first 60 days of COBRA coverage, you can extend coverage from 18 months to 29 months, though the plan can charge up to 150% of the premium during the extra 11 months.10U.S. Department of Labor. Health Benefits Advisor – COBRA Disability Extension Notice deadlines are strict, so file the paperwork promptly.
ACA Marketplace
Retiring and losing job-based coverage qualifies you for a Special Enrollment Period on the Health Insurance Marketplace, with 60 days from your separation date to enroll. Marketplace plans may come with premium tax credits based on your income, which can drop the cost well below COBRA. If you’re eligible for retiree health coverage from your employer but haven’t enrolled in it, you may still qualify for marketplace subsidies.11HealthCare.gov. Health Care Coverage for Retirees Once you elect COBRA, you generally can’t drop it mid-year and switch to a marketplace plan outside Open Enrollment; if COBRA runs out on its own, that opens a new Special Enrollment Period.
Medicare if You’re 65 or Older
If you’re 65 or older, Medicare becomes your primary coverage. Most people qualify for premium-free Part A based on 40 or more quarters of Medicare taxes. Those who don’t pay up to $565 per month for Part A in 2026.12Medicare.gov. 2026 Medicare Costs The standard Part B premium is $202.90 per month in 2026.13Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles
If you delayed Medicare because you had employer coverage, you get an eight-month Special Enrollment Period starting when your employment or that coverage ends, whichever comes first.14Social Security Administration. How to Apply for Medicare Part B During Your Special Enrollment Period Miss it and you face a permanent 10% Part B surcharge for each full 12-month period you could have had Part B but didn’t.
Here’s the trap: COBRA does not count as employer-based coverage for this purpose. Neither does retiree health coverage or VA benefits.14Social Security Administration. How to Apply for Medicare Part B During Your Special Enrollment Period If you retire at 65, elect COBRA, and wait to sign up for Medicare until COBRA runs out, you’ll be hit with the penalty. Enroll in Medicare when you retire, regardless of what else you carry.
Part D has its own late enrollment penalty if you go without creditable prescription drug coverage after becoming Medicare-eligible: 1% of the national base beneficiary premium ($38.99 in 2026) for each month you lacked coverage, added to your Part D premium for as long as you have Medicare drug coverage.15Medicare.gov. Avoid Late Enrollment Penalties
Retiring Before 65
If you retire before 65, you won’t qualify for Medicare based on age. You’ll need to bridge the gap with COBRA, a marketplace plan, or a spouse’s plan (losing your own job-based coverage is a life event that opens enrollment on a spouse’s plan). The exception: after 24 months of SSDI benefits, Medicare eligibility kicks in regardless of age.3Centers for Medicare & Medicaid Services. Original Medicare (Part A and B) Eligibility and Enrollment Another reason the SSDI question deserves attention before you retire.
Close Out the Loose Ends With Your Employer
Whether you’re owed a payout for unused vacation or sick time depends on where you work. No federal law requires private employers to pay out accrued vacation. About 20 states require it by statute, and several others require it only if the employer has a written policy promising payout. Check your handbook and your state’s rules before assuming that balance shows up in your final check. Federal employees are treated differently: unused sick leave is converted into additional service credit for annuity purposes under CSRS and FERS, though it can’t be used to establish retirement eligibility or calculate the high-three average salary.
Employer group life insurance typically ends at retirement. Most policies give you a 31-day window to convert group coverage to an individual policy without a medical exam. The individual policy costs more, but if your health condition would make you uninsurable on the open market, conversion may be your only option. Miss the deadline and you lose the right to convert.
When you’ve decided, notify HR in writing with your intended retirement date. There’s no legal requirement for a specific notice period in most private-sector jobs, but two to four weeks is typical and helps final pay and benefits process cleanly. Expect a stack of forms: a retirement application, pension or 401(k) distribution elections, health insurance continuation elections, beneficiary updates. Some pension elections require notarization. Before you sign the final paperwork, ask for a written summary showing your pension amount, vesting status, final 401(k) balance, and the exact date your health and life insurance coverage ends. That summary is your last chance to catch errors while they’re still fixable.
