The TSP Secure Path
A plain-English walk through the decision every federal employee eventually faces: what happens to your TSP when you stop working. No jargon, no products, no pressure.
Why this decision is different for feds
Most Americans arrive at retirement with a pile of savings and a vague plan. You arrive with something more structured: a pension, Social Security, and a TSP — and, usually, a retirement date you've been able to see coming for years.
That's a real advantage. But it comes with a quirk. The first two pieces are largely decided for you: your FERS pension is a formula based on your service and your high-3, and Social Security is what it is. The third piece — your TSP — is the one where you actually make choices. And it's the one your agency spent the least time explaining.
Most federal employees can tell you, in detail, how to contribute to the TSP. Far fewer can name what happens to it the day they stop.
Step 1 — Know where you stand
Before options mean anything, four facts about your own situation do most of the work:
- Your system. FERS or CSRS. They behave differently, and CSRS folks are a shrinking but very different group.
- Your service years. This drives your pension calculation and your eligibility dates.
- Your timeline. "Retiring next year" and "retiring in eight years" are different conversations entirely.
- What your TSP is actually in today. A balance that's 90% G Fund and a balance that's 90% C Fund are not the same balance, and they don't face the same questions.
None of this requires account numbers or precise figures. Ranges are enough to have a sensible conversation.
Step 2 — Understand all five options
When you separate from federal service, the TSP gives you a defined set of choices. Here they are. Read them as a menu, not a ranking — there is no universally correct answer, and anyone who tells you otherwise before knowing your situation is selling something.
Option 1 — Leave it in the TSP
You separate, and your money stays exactly where it is. You keep the TSP's fund lineup and its famously low administrative costs. You can still move money between funds.
What it's good at: cost, simplicity, and not making an irreversible decision while you're busy retiring. What it doesn't do: it doesn't, by itself, turn your balance into a monthly income, and the TSP's withdrawal mechanics are more rigid than some alternatives.
Doing nothing is a real option, and for many feds it's a perfectly reasonable one. Be sceptical of anyone who treats "leave it in the TSP" as an obviously wrong answer.
Option 2 — Installment payments
You tell the TSP to pay you on a schedule: monthly, quarterly, or annually. You can choose a fixed dollar amount, or have payments calculated based on life expectancy. You can make changes to installments, within the TSP's rules.
What it's good at: turning a balance into something that behaves like a paycheque, while keeping the money in the TSP. What to understand: the payments last as long as the money does — a fixed amount from a finite balance is not the same thing as income for life.
Option 3 — A lump sum, full or partial
You take some or all of it out. Simple to describe, and the easiest option to get badly wrong.
What to understand: this is the choice with the largest tax consequences, and taxes are the part people most often underestimate. A large withdrawal in a single year is a taxable event in that year. There are also withholding rules, and — depending on your age and circumstances — potential early-withdrawal considerations. This is precisely the kind of thing to model before you file, not after.
Option 4 — The TSP's lifetime income option
The TSP offers a way to convert part or all of your balance into payments that continue for life, purchased through the TSP's outside provider. You hand over a lump sum; it hands back a defined payment on a schedule, for as long as you live (with variations depending on the features you select — including options that continue payments to a spouse).
What it's good at: predictability. It's the option that most directly answers "what if I live a long time?" What to understand: it's generally a one-way door. You're trading flexibility and access to the balance for certainty of payment. Whether that's a good trade depends entirely on your other income, your health, your spouse, and your temperament — not on a chart.
Option 5 — Transfer or roll it over
You move the balance to an IRA or another eligible employer plan. Done as a direct transfer, this is generally not a taxable event at the time of the move.
What it opens: a wider set of choices than the TSP's own menu, and different withdrawal mechanics. What it closes: the TSP's cost structure and the G Fund, which has no exact private-sector equivalent. It can also change how certain rules apply to you.
This option gets marketed to federal employees more aggressively than the other four combined. That's not a reason to dismiss it — it's a reason to understand it properly, in both directions, and to ask who benefits from the recommendation.
Step 3 — Map the income gap
Here's the exercise that makes the five options concrete. Roughly:
- Estimate what your FERS pension is expected to pay.
- Estimate your Social Security, and note when you plan to claim it — including whether you're bridging a gap with the FERS supplement.
- Add them up, and compare against what you actually expect to spend.
Whatever is left over is the job your TSP has to do. That number — not a sales pitch — is what should drive which of the five options you spend time on. If your pension and Social Security comfortably cover your spending, your TSP decision is a very different one than if there's a meaningful gap.
We wrote this out in more detail in The FERS Pension Gap.
Step 4 — Ask better questions
Whoever you end up talking to — us, your agency's retirement counsellor, a professional, or your brother-in-law — these are worth asking:
- Which of the five options are we not discussing, and why?
- What does this cost me — in fees, in taxes, and in flexibility I give up?
- Is this reversible? If I change my mind in two years, what happens?
- How do you get paid if I do this? How do you get paid if I don't?
- What happens to my spouse under this option?
- What does this look like if I live to 95? What if I don't?
A good conversation survives all six questions. A sales pitch usually doesn't.
A note on timing and paperwork
Federal retirement paperwork is not instant, and processing times have been a known pain point. The practical implication is simple: the time to understand your options is before your package goes in, not while you're waiting on it. Decisions made under time pressure, with income uncertainty in the background, are rarely your best ones.
