How Long TCC Lasts: 18 or 36 Months, and the 2 Deadlines You Must Not Miss

Temporary Continuation of Coverage buys you time after FEHB ends. Exactly how much time depends on who you are in the transaction — and the two clocks are very different lengths.

The short answer: How long TCC lasts depends on who is enrolling. A separating employee gets up to 18 months from the date of separation. A child who ages out, or a former spouse after a divorce, gets up to 36 months from the qualifying event. Both pay 102% of the full premium.

Key takeaways

• Separating employees: TCC runs up to 18 months after separation (OPM).
• Children and former spouses: up to 36 months after the qualifying event.
• You pay the employee share and the government share, plus a 2% administrative charge — 102% of the total premium.
• The election window is 60 days, and for children and former spouses a separate 60-day notification duty comes first.

How long TCC lasts for each category

How long TCC lasts is set by the qualifying event, not by the date you elect or the date your paperwork is processed. The 18-month and 36-month clocks both start at the event.

• Separating employee — 18 months from the date of separation.
• Child losing eligibility — 36 months from the date eligibility ends, typically turning 26.
• Former spouse — 36 months from the date of the divorce or annulment.

Because the clock starts at the event, a slow election does not extend the coverage. It only shortens the useful portion, since TCC takes effect the day the free 31-day extension ends and is applied retroactively to that date — with premiums owed for the whole retroactive stretch.

What does 102% actually cost?

Under regular FEHB the government pays most of the premium. Under TCC you pay all of it. On a plan whose total premium is $900 a month — government share plus enrollee share — TCC costs $918 a month: the full $900 plus the 2% charge.

If the enrollee share had been $300, the jump is from $300 to $918. That is the number that catches people, not the duration.

What are the deadlines that end TCC early?

Three things cut the clock short:

• Missing the 60-day election window. For a separating employee it runs 60 days from the separation or from the employing office’s notice, whichever is later. Miss it and TCC is gone.
• Missing the 60-day notification duty. For a child or former spouse, someone must tell the employing office within 60 days of the event. The election window does not open until that happens.
• Non-payment. TCC terminates for unpaid premiums, and it is not reinstated.

The 31-day extension of coverage is separate and automatic. It is free, it applies whenever FEHB ends other than by cancellation, and it exists to give you a conversion window — not to add a month to TCC.

How does TCC fit the five-year rule?

TCC is a bridge, not a substitute for carrying FEHB into retirement. Time on TCC does not help you satisfy the FEHB five-year rule. For the full mechanics, eligibility, and enrollment steps, see our parent guide to FEHB Temporary Continuation of Coverage.

Frequently asked questions

Can TCC be extended past 18 or 36 months?
No. How long TCC lasts is fixed by statute, and there is no extension for hardship or for a pending job offer.

Does a former spouse’s 36 months run alongside the employee’s 18?
They are independent clocks tied to different qualifying events, and they can overlap.

Is TCC the same coverage as before?
You may choose any plan in the FEHB program; the benefits are the same as for any enrollee. Only the cost and the duration change (OPM).

Plan the gap before it opens

TCC is usually the fallback when something else did not line up. Fed Pilot’s free federal retirement benefits workshops cover FEHB continuation, the five-year rule, and the coverage decisions that keep you from needing a bridge at all. Register for an upcoming workshop.
