Your 12-month pre-retirement runway
Most of what you do in your final year can be fixed later. A handful of things cannot. This lesson sequences the federal deadlines that close permanently when you separate, counting backward from your retirement date so each one still has room to act on.

Why sequence your final year at all?
Because a few federal deadlines close for good on your last day. Most retirement decisions stay open: you can rebalance the Thrift Savings Plan (TSP), change your mind about a withdrawal, or adjust your budget. A short list cannot be reopened once you separate, and that list is what this lesson schedules.
This is a different question from whether you are ready. The readiness checklist asks whether your income, savings, and debt support retiring at all. This lesson assumes you have answered that and picked a date, then works backward from it.
Three things drive the ordering. Some fixes require moving your retirement date, so they need the most warning. Some can only be done in a window that opens once a year. Some just need more lead time than people expect, because another office has to act.
The table below is the whole lesson in one view. Each row is covered in its own slide, with a link to the lesson that owns the underlying rule.
What has a deadline, and when to act
| When | What closes |
|---|---|
| About 12 months out | Five-year rule and military deposit |
| About 6 months out | Health enrollment changes for a survivor |
| About 60 days out | Your application, and agency processing time |
| Final weeks | Leave balance and any TSP loan |
| After you retire | The survivor election, briefly |
How far ahead should I start planning my federal retirement?
A year gives you room for the deadlines whose only fix is a later date, which is the real reason for the long runway. If you are inside a year, you can still retire on schedule. You simply lose the ability to correct a shortfall in creditable service or a missed insurance requirement without moving the date.
What is the difference between this and a readiness checklist?
A readiness checklist asks whether your finances support retiring. This is a schedule, and it asks what has a deadline. The two are complementary: confirm you are ready first, then work backward from your date so nothing with a hard cutoff gets missed.
What can only be fixed by moving your date?
Two things, and both are counted backward from the day you separate. That is what makes them different from everything else on this list. If you come up short, no form fixes it. You either retire later or you lose the benefit.
The first is the health insurance five-year rule. To carry Federal Employees Health Benefits (FEHB) into retirement you generally need five years of continuous enrollment immediately before you separate. The FEHB lesson covers the rule and its exceptions. The scheduling point is what it implies: if you are four years and eight months in, your only remedy is a later date.
The second is a service deposit. Military service and some civilian service count toward your annuity only if you pay a deposit, and interest compounds while it sits unpaid. The two deadlines are not the same. A military deposit must be paid before you separate, which is why it belongs on this list. A civilian deposit can be paid any time before OPM finalizes your claim, months after your last day. The military buyback lesson covers the calculation, and civilian service deposits covers the later window.
Both are worth checking even if you are confident. An enrollment gap from a decade ago, or a deposit you thought your agency had processed, is the kind of thing that surfaces late and cannot be corrected on your last day.
What happens if I do not meet the FEHB five-year rule?
You lose the ability to carry FEHB into retirement, and no election or payment restores it. The rule counts the five years immediately before separation, so the only way to satisfy it is to stay enrolled and stay employed longer. That is why it belongs at the front of your runway rather than in your final months.
Can I pay a service deposit after I retire?
It depends which one. A military deposit must be paid before you separate, and once you are retired that window is closed. A civilian deposit or redeposit is more forgiving: you can pay it any time before OPM finalizes your retirement claim, which is generally months after your last day. Confirm both balances with your agency well before your date, because interest compounds on either while it sits unpaid.
How do I check my creditable service before I retire?
Ask your agency HR office for a service history review, which walks your record for gaps, unpaid deposits, and periods that may not be creditable. Do it early enough that a problem can still change your plans. Your annuity estimate is only as accurate as the service record behind it.
Which changes have a once-a-year window?
Your health enrollment tier is the one that catches people, and it matters most if you are electing a survivor annuity. Outside a qualifying life event, the annual Open Season is the only routine chance to change it.
The rule behind it is easy to miss. For your spouse to keep FEHB after your death, two conditions have to hold together: they must receive a monthly survivor annuity, and your enrollment at retirement must be Self Plus One or Self and Family. A Self Only enrollment ends your spouse’s coverage when you die, no matter what survivor annuity you elected.
That makes it a scheduling problem. The survivor election is made on your retirement application, but the enrollment tier that makes it useful can generally only be changed during Open Season. If your Open Season passes while you are enrolled Self Only, you may reach your retirement date unable to fix the mismatch.
The survivor election lesson covers how the election itself works and what it costs. Check your enrollment tier against it while an Open Season is still ahead of you.
What your spouse needs to keep FEHB
All two required
A monthly survivor annuity
Elected on your retirement application
Self Plus One or Self and Family
Generally changed only in Open Season
Your spouse keeps FEHB for life
At the same premium share you paid
Miss either one, and their coverage ends when you die
Does my spouse automatically keep FEHB if I elect a survivor annuity?
No. The survivor annuity is only half of what is required. Your enrollment at retirement must also be Self Plus One or Self and Family. If you are enrolled Self Only, your spouse loses FEHB when you die even though you elected and paid for a survivor annuity throughout your retirement.
When can I change my FEHB enrollment before retiring?
Generally during the annual Open Season, or when you have a qualifying life event such as a marriage or a change in family status. Retiring is not by itself an event that lets you switch tiers. Plan the change for an Open Season that falls before your retirement date rather than assuming you can adjust it on the way out.
How much lead time does your agency actually need?
More than most people assume, and the number is specific. OPM says an agency needs a minimum of 60 days to process a retirement application before it reaches OPM at all. That splits into about 30 days for the human resources office and 30 days for payroll.
OPM gives a second 60-day marker. Meet your benefits office at least 60 days before your separation date to go through your benefits and your annuity estimate. That meeting is also where service-record problems tend to surface, which is one reason the earlier slides matter.
Those 60 days are not your waiting time. They are your agency’s share of the work, and OPM’s own processing starts only after the packet arrives. The OPM processing lesson covers what happens once it does, including interim payments.
If you have already separated, submit as soon as you can. OPM advises filing at least 30 days ahead of a separation date in that situation, and personnel offices often want it sooner. Filing early costs nothing and is the cheapest delay insurance available.
When should I submit my federal retirement application?
Aim for at least 60 days before your separation date, because that is the minimum your agency needs: roughly 30 days for human resources and 30 days for payroll. Earlier is better. Nothing is lost by filing ahead of schedule, and a late packet delays every payment that follows it.
Does filing early make my annuity start sooner?
No. Your annuity start date is set by your separation date, not by when you file. Filing early protects the processing timeline instead, so your case reaches OPM promptly and your interim payments begin without an avoidable gap. It does not move up the date your annuity is payable from.
What should I bring to the benefits office meeting?
Bring your service history, any documentation for military or non-deduction civilian service, your current insurance enrollments, and your intended separation date. The point of meeting 60 days out is to surface a problem while it can still be fixed, so go in expecting to verify the record rather than just collect an estimate.
What has to be settled before your last day?
The final weeks are about balances rather than decisions. Two of them follow you out the door if you leave them unresolved.
Your leave account is the first. Confirm your annual leave balance and whether you are carrying advanced annual leave, which you generally have to refund at separation. The final paycheck lesson covers how each is settled and the exceptions to the refund.
An outstanding TSP loan is the second, and it carries the tighter clock. You have 90 days from separation to repay it before the balance is declared a taxable distribution. The decision is easier to make while you are still drawing a salary, which is the argument for handling it now rather than after.
This is also the last comfortable moment to check your insurance enrollments read the way you expect. Correcting an enrollment record is a different task once you are no longer on your agency’s rolls.
What should I settle in my last month of federal service?
Confirm your annual and sick leave balances, resolve any advanced annual leave you owe, decide what to do about an outstanding TSP loan, and verify your health and life insurance enrollments. Each is far easier to correct while you are still employed than after your record has closed.
Why deal with a TSP loan before I leave?
Because the 90-day repayment window starts at separation, and missing it converts the outstanding balance into taxable income for that year. Deciding while you still have a paycheck gives you options that disappear once your salary stops. The final paycheck lesson covers the tax consequences in full.
What is still changeable after you retire?
Less than people expect, and the one meaningful exception is time-boxed. Your survivor election has two short windows after your annuity starts, and then it is fixed for life.
The first window is brief. You can cancel or reduce the survivor election within 30 days of your first regular monthly payment, which OPM defines as the first recurring payment at your finalized rate. An interim payment or an adjustment payment does not start that clock.
The second window runs longer and moves only one direction. Within 18 months of retirement you may elect a survivor annuity or increase a partial one, but you may not reduce what you chose at retirement. The survivor election lesson covers both windows, the deposit an increase requires, and the permanent reduction that comes with it.
Everything else on this list has already closed. That asymmetry is the reason to run a schedule at all: the decisions with the longest consequences are the ones with the shortest windows. To see how the whole picture holds together before you commit, run your free readiness score.
Can I change my survivor election after I retire?
Briefly, and in a limited direction. You may cancel or reduce it within 30 days of your first regular monthly payment. After that, and up to 18 months from retirement, you may only elect or increase a survivor annuity, never reduce one. Past 18 months the election is permanent.
Does an interim payment start the 30-day clock?
No. OPM counts from your first regular monthly payment, meaning the first recurring payment at your finalized annuity rate. Interim payments and the adjustment payment that follows finalization do not begin the window. That distinction matters, because interim pay can run for months before the clock starts.
