During FMLA leave, your employer must continue paying its share of your health insurance premiums, and you must continue paying yours. The split stays exactly the same as when you’re actively working. If you normally cover 25% of the monthly premium through payroll deductions and your employer covers 75%, that arrangement doesn’t change just because you’re on leave.
What does change is how your portion gets paid, especially if your leave is unpaid. That’s where things get more complicated.
Your Employer’s Legal Obligation
Federal law requires your employer to maintain your group health plan coverage on the same terms and conditions as if you had never left. That means the same plan, the same employer contribution, and the same coverage for any family members who were already on the plan. Your employer cannot reduce its share, switch you to a different plan, or charge you extra administrative fees while you’re on FMLA leave.
If your employer introduces a new health plan or changes benefits while you’re on leave, you’re entitled to those changes just like any other employee. The same goes for premium increases or decreases. If premiums go up for the entire workforce, your share goes up too. If they drop, you pay less.
Paid vs. Unpaid Leave Changes How You Pay
If you’re using paid leave (vacation, sick time, or paid family leave) that runs concurrently with FMLA, your premium share is deducted from your paycheck the same way it always has been. Nothing changes on your end.
Unpaid FMLA leave is different. With no paycheck to deduct from, your employer needs another way to collect your share. Federal regulations give employers several options, and your employer must notify you in writing about which method they’ll use before your leave begins. The most common arrangements include:
- Same-schedule payments: You send a payment on the same dates your payroll deduction would normally occur, typically every two weeks or monthly.
- COBRA-style schedule: You pay on the same timeline used for COBRA continuation coverage, which is monthly.
- Pre-payment: If your leave is foreseeable, you and your employer can agree to increase your payroll deductions before leave starts to cover the premiums in advance.
- Catch-up payments: You pay nothing during leave and make up the difference after you return to work.
- Employer’s existing leave-without-pay policy: Whatever system your employer already uses for other employees on unpaid leave, as long as it doesn’t require prepayment or charge you higher premiums than active employees.
Your employer can require you to pay the employer directly or pay the insurance carrier, but either way, they cannot tack on any administrative surcharge.
Tax Implications of Each Payment Method
How you pay your premiums during FMLA leave affects whether those payments are made with pre-tax or after-tax dollars. If you pre-pay before leave starts using payroll deductions, those contributions can remain pre-tax. The same is true for catch-up payments made through payroll deductions after you return.
If you’re making direct payments to your employer or insurer during unpaid leave (the pay-as-you-go approach), those contributions are generally made with after-tax dollars. The exception is if the payments come from taxable compensation your employer still owes you, like accrued vacation or sick days, in which case they can stay pre-tax.
What Happens If You Miss a Payment
If your premium payment is more than 30 days late, your employer can drop your health coverage. But they can’t do it without warning. Federal rules require your employer to mail you a written notice at least 15 days before terminating coverage. That notice must include the specific date your coverage will end and give you until that date to make the payment.
So in practice, you have roughly 45 days from a missed due date before coverage actually stops: 30 days of grace, then 15 days of mandatory written notice. If your employer has an existing policy that provides a longer grace period, that longer window applies instead.
Repayment If You Don’t Return to Work
Here’s where many people are surprised. If you don’t come back to work after FMLA leave expires, your employer can require you to repay the employer’s share of premiums it paid during your unpaid leave. Not just your share, but theirs too.
There are two exceptions. Your employer cannot recover those costs if you don’t return because of a serious health condition (yours or a covered family member’s) or because of circumstances beyond your control, such as a spouse being transferred to a job in another city or a parent needing full-time care. If your employer disputes your reason, they can ask for medical certification, and you have 30 days to provide it.
The threshold for “returning to work” is 30 calendar days. If you come back and work for at least 30 days, you’ve satisfied the return requirement and your employer cannot seek repayment of its premium contributions.
When FMLA Ends and COBRA Begins
Taking FMLA leave itself does not trigger COBRA eligibility. Your employer is maintaining your coverage throughout, so there’s no loss of benefits to trigger continuation rights. The qualifying event occurs on the last day of FMLA leave if you don’t return to work and would otherwise lose coverage.
At that point, your COBRA maximum coverage period (typically 18 months) is measured from your last day of FMLA leave, not from the day you originally stopped working. So if you took 12 weeks of FMLA leave and then didn’t return, COBRA would start on the day after those 12 weeks ended. Under COBRA, you pay the full premium (both the employer’s and employee’s share), plus a 2% administrative fee.
Practical Steps Before Your Leave Starts
Your employer is required to give you advance written notice explaining how premium payments will work during your leave. If you haven’t received this, ask your HR department directly. Knowing the payment method, schedule, and due dates before leave starts prevents surprises.
If your leave is foreseeable, such as for a planned surgery or an expected baby, pre-paying through increased payroll deductions is often the simplest option. You avoid the hassle of writing checks while you’re recovering or caring for a newborn. If pre-payment isn’t possible, set calendar reminders for each due date so you stay within the 30-day grace window and keep your coverage intact.
