Quick summary: Once you separate, your TSP gives you five ways to take money out — installment payments, partial withdrawals, a single full withdrawal, a life annuity, or a rollover to an IRA. Installments are the workhorse for most retirees. The decisions that matter most are not "which fund" but how much to draw (sequence-of-returns risk in the first decade), which tax bucket to draw from (traditional vs. Roth), and when withdrawals become mandatory (RMDs at 73 under SECURE 2.0). When taken directly from the TSP, each withdrawal is pulled proportionally across your traditional and Roth balances — you cannot cherry-pick one bucket (an IRA, by contrast, can).

Who This Article Is For
- FERS employees approaching retirement who want to understand how to turn a TSP balance into income
- Recent retirees deciding between installment payments, partial withdrawals, and leaving the money invested
- Anyone weighing whether to keep their money in the TSP or roll it to an IRA
- Retirees trying to manage their tax bracket, RMDs, and the order they draw from traditional vs. Roth
- Federal employees who want to avoid the early-withdrawal penalty and the most common, irreversible tax mistakes
The TSP is, for many federal employees, the largest single asset they own at retirement — often larger than the present value of their pension. Yet the pension comes with a formula and a counseling appointment, while the TSP comes with a login screen and a menu of options nobody walks you through. This guide is that walkthrough.
Your Five Withdrawal Options
Once you separate from federal service, the TSP gives you five ways to access your money. You can combine several of them.
Installment Payments
A recurring monthly, quarterly, or annual payment — either a fixed dollar amount or one calculated from your life expectancy. You can start, stop, or change the amount at any time.
Partial Withdrawals
A one-time lump sum of $1,000 or more, taken whenever you need it. You can take multiple partial withdrawals and still run installments alongside them.
Single Full Withdrawal
Take the entire balance at once. Rarely the right move for a traditional balance — it can push a year of income into the top tax brackets.
TSP Life Annuity
Hand part or all of your balance to the TSP's annuity provider in exchange for a guaranteed monthly payment for life. Irreversible once purchased.
Rollover to an IRA
Move some or all of the balance to a traditional or Roth IRA. More investment choices and flexibility — but you give up the TSP's rock-bottom fees and the G Fund.
Since the TSP Modernization Act took effect, these options are far more flexible than the rigid all-or-nothing rules many retirees still remember. You can take installments and partial withdrawals, change your installment amount whenever you like, and leave the rest invested in the funds you choose. There is no longer any requirement to make a withdrawal election by a particular age — only the RMD rules force money out, and not until 73.

The Age Rules That Govern Penalties
Three age thresholds drive almost every TSP withdrawal decision. Get these wrong and you can hand the IRS a 10% penalty that was entirely avoidable.
The Age-55 Rule
If you separate from federal service in or after the calendar year you turn 55, your TSP withdrawals are not subject to the 10% early-withdrawal penalty — even before 59½. For special category employees (LEO, firefighter, ATC), the threshold is age 50, or any age with 25 years of covered service.
Age 59½
The universal penalty-free age. After 59½, the 10% penalty never applies, regardless of when you separated. This is also the age in-service withdrawals become available if you are still working.
Age 73 (RMDs)
Under SECURE 2.0, required minimum distributions begin at 73 (rising to 75 for those born in 1960 or later). At this point withdrawals are no longer optional — the IRS forces a minimum each year.
⚠ The Rollover Trap
The age-55 rule is a TSP feature, not an IRA feature. If you retire at 56 and roll your TSP into an IRA, you lose the penalty-free access — IRA withdrawals before 59½ are penalized unless they fit a separate exception. If there's any chance you'll need the money between 55 and 59½, leaving it in the TSP preserves a benefit an IRA cannot replicate.
Installment Payments: The Workhorse
For most retirees building a paycheck replacement, installment payments are the default tool. You choose:
- Frequency: monthly, quarterly, or annual.
- Type: a fixed dollar amount you set (e.g., $2,000/month), or an amount the TSP calculates from your life expectancy using IRS tables, which recomputes each year.
- Source mix: payments come proportionally from your traditional and Roth balances (more on this below).
The flexibility is the point. You can raise the amount in a strong market year, cut it in a downturn, pause it entirely, or take a one-time partial withdrawal on top of it — all without restarting the election. That makes installments a genuine retirement-income tool rather than a one-way door.
Withholding Detail That Trips People Up
Installments expected to last less than 10 years are treated as "eligible rollover distributions" and carry a mandatory 20% federal withholding. Installments expected to last 10 years or more, or based on life expectancy, are withheld like wages (you set the rate). The single full withdrawal and most partial withdrawals also carry the mandatory 20%. Withholding is not the same as the tax you owe — it's a prepayment, trued up on your return.
Why Your FERS Pension Changes the Withdrawal Math
Most TSP withdrawal advice is written for people who don't have a pension — and federal retirees do. A private-sector retiree leans almost entirely on their portfolio, so a bad market early in retirement can be existential. A FERS retiree has a foundation of guaranteed, largely inflation-protected income underneath the TSP. That changes what a "safe" withdrawal rate even means for you.
You typically retire with four income sources that have nothing to do with the stock market:
FERS pension
A lifetime annuity with partial COLA adjustments — it never runs out and never falls in a crash.
Social Security
Fully COLA-adjusted, guaranteed for life — and you control when it starts (62 to 70).
FERS Supplement
If eligible, a pension-like bridge payment from your MRA until 62 — more guaranteed income in the very years sequence risk is sharpest.
FEHB
Subsidized health coverage for life — removing the single biggest unbudgeted risk most retirees face.
The practical consequence: if your pension, supplement, and Social Security already cover most of your essential spending, your TSP is mostly funding discretionary expenses — travel, gifts, the occasional big purchase. Discretionary spending is flexible, and flexibility is exactly what neutralizes sequence-of-returns risk. You can pause the trip in a down year without going hungry. A retiree whose portfolio funds the rent does not have that luxury.
This is why copy-pasting generic "is 4% safe?" advice can mislead a federal employee in both directions — it can scare you into under-spending a retirement your pension already secured, or lull you into ignoring the years where even a federal retiree is exposed. The honest answer always depends on the gap between your guaranteed income and your real spending. See Can I Retire at 57 vs. 62? and FERS Supplement Explained for how the guaranteed layer is built, and the FERS Pension Calculator to size the foundation itself.
How Much Can You Safely Withdraw?
The hardest question in retirement isn't which option — it's how much. Draw too much early and you can run the account dry; draw too little and you under-live a retirement you funded for decades.
The classic starting point is the 4% guideline: withdraw about 4% of the balance in year one, then adjust that dollar figure for inflation each year. On a $500,000 balance that's roughly $20,000 in the first year. It is a rule of thumb, not a guarantee — but it frames the order of magnitude.
Illustrative example only. Figures use a hypothetical retiree profile. The 4% guideline is a planning heuristic, not a promise; the sustainable rate for your situation depends on your time horizon, asset mix, other income, and market sequence. Your numbers will differ.
| TSP balance | ~4% first-year draw | Monthly equivalent |
|---|---|---|
| $250,000 | $10,000 | ~$833/mo |
| $500,000 | $20,000 | ~$1,667/mo |
| $750,000 | $30,000 | ~$2,500/mo |
| $1,000,000 | $40,000 | ~$3,333/mo |
The reason a federal retiree can often be a little more aggressive than a private-sector retiree: the FERS pension and Social Security cover a large share of essential expenses, so the TSP is doing less of the heavy lifting. The reason to be more conservative in the first decade is the risk in the next section.

Sequence-of-Returns Risk
Two retirees can earn the exact same average return over 25 years and end up in completely different places — one comfortable, one out of money — purely based on the order the returns arrive.
"A market crash the year before you retire is an inconvenience. The same crash the year after you retire — while you're selling shares to live on — can permanently impair the account. Same average return, very different outcome."
When you're withdrawing, a bad early market forces you to sell more shares to fund the same dollar of income, and those shares aren't there to recover when the market rebounds. This is why the years immediately around retirement matter disproportionately.
Both retirees start with $500,000, withdraw $28,000/year, and earn the same 18 annual returns (2.9% average) — only the order is reversed.
Illustrative only. Identical average return, identical withdrawals — the order of returns alone determines whether the money lasts.
Two practical defenses:
- A cash/G Fund buffer. Holding one to three years of withdrawals in the G Fund (or cash) lets you pause selling equities during a downturn and draw from the buffer instead. The G Fund's principal protection is purpose-built for exactly this job.
- Flexible installments. Because TSP installments can be cut at any time, trimming withdrawals in a down year — rather than mechanically inflation-adjusting — meaningfully extends the life of the account.
This is a strategy question, not a fund-picking question. The L Funds, G Fund, and a withdrawal rule you'll actually follow matter far more than chasing the highest-returning fund.

Traditional vs. Roth TSP Withdrawals
If you have both a traditional and a Roth balance in the TSP, there is one rule that surprises almost everyone:
The Proportional Rule
Every TSP withdrawal comes out proportionally from your traditional and Roth balances. If your account is 80% traditional and 20% Roth, a $2,000 withdrawal is $1,600 traditional and $400 Roth — you cannot choose to pull only from one. This is the single biggest reason retirees who want bucket-by-bucket tax control roll the Roth portion to a Roth IRA, where it can be drawn independently.
The tax treatment of each piece:
- Traditional TSP withdrawals are taxed as ordinary federal income (and usually state income). This is money that was never taxed going in.
- Roth TSP qualified withdrawals are completely tax-free — both contributions and earnings — provided you are at least 59½ and five years have passed since your first Roth TSP contribution. If you withdraw earnings before meeting both tests, the earnings portion is taxable.
The strategic implication: in early retirement, many federal retirees deliberately draw from traditional dollars (and even do Roth conversions) to fill up the lower tax brackets before Social Security and RMDs stack on top at 73. The proportional rule limits how surgically you can do that inside the TSP — which is the main argument for moving the Roth portion out.
Required Minimum Distributions (RMDs)
Starting at age 73, the IRS requires you to withdraw a minimum amount each year, calculated from your prior year-end balance and an IRS life-expectancy factor. SECURE 2.0 changed the landscape:
RMD age is now 73
For those reaching 72 after 2022, RMDs start at 73 — and at 75 for anyone born in 1960 or later. Your first RMD can be delayed to April 1 of the year after you turn 73, but doubling up two RMDs in one year can spike your bracket.
Roth TSP no longer has lifetime RMDs
As of 2024, the Roth balance inside the TSP is no longer subject to RMDs during your lifetime — bringing it in line with Roth IRAs. Only the traditional balance drives your required distribution.
The penalty for missing one
Failing to take an RMD triggers an excise tax on the shortfall (reduced under SECURE 2.0, and lower still if corrected promptly). The TSP will generally pay out your RMD automatically if you haven't withdrawn enough — but don't rely on that across multiple accounts.
The planning game with RMDs is played in the years before they start: the larger your traditional balance at 73, the larger the forced, fully taxable withdrawal — which can also raise Medicare premiums (IRMAA) and the taxable share of your Social Security. Drawing down or converting traditional dollars in your 60s is how retirees blunt that.
The TSP Annuity Option
You can convert part or all of your balance into a life annuity through the TSP's annuity provider. In exchange for the lump sum, you receive a guaranteed monthly payment for life, with options for a joint annuitant and survivor features.
The case for it: it eliminates sequence risk and longevity risk for the portion you annuitize — you cannot outlive it, and a market crash can't touch it. For a retiree who is anxious about running out of money and is light on guaranteed income, it converts a pile of money into a paycheck.
The case against it: it is irreversible, the payment is generally fixed (inflation erodes it over a long retirement), and you give up the flexibility and the legacy value of the balance. Many federal retirees find they already have substantial guaranteed, COLA-adjusted income from the FERS pension and Social Security — so annuitizing the TSP on top adds rigidity without solving a problem they actually have.
This is the option to model carefully and rarely choose in full. Annuitizing a slice to cover a specific essential-expense gap is more defensible than annuitizing the whole balance.
Should You Roll Over to an IRA?
This is the most consequential — and most heavily marketed-to — decision. Advisors have a financial incentive to recommend rolling your TSP into an IRA they manage. Here's the honest tradeoff.
Reasons to Roll Out
- Independent control of traditional vs. Roth withdrawals (no proportional rule)
- Far more investment choices than the five TSP funds + L Funds
- Qualified Charitable Distributions from an IRA at 70½
- Easier estate/beneficiary flexibility
Reasons to Stay
- The TSP's expense ratios are among the lowest of any retirement plan, anywhere
- The G Fund — government-backed principal with intermediate yields — has no true equivalent in any IRA
- The age-55 penalty-free rule (lost the moment you roll out before 59½)
- Strong federal creditor protections and simplicity
A common middle path: keep the bulk of the balance in the TSP for the fees and the G Fund, and roll only the Roth portion (or a slice) to an IRA to gain withdrawal control. You are not forced to choose all-or-nothing.
Coordinating With the FERS Supplement
One subtlety that catches early retirees off guard — but in your favor:
TSP Withdrawals Are Not "Earned Income"
The FERS Supplement is reduced dollar-for-dollar above an annual earned income limit ($24,480 in 2026). TSP withdrawals are not earned income — they don't count against the supplement earnings test. That makes the TSP a useful bridge between an early retirement at your MRA and age 62, when you can draw income without endangering the supplement. (Wages and self-employment income, by contrast, do count.)
For the full picture, see FERS Supplement Explained and Can I Retire at 57 vs. 62?.
Common Mistakes
Rolling out before 59½ and forfeiting the age-55 rule
If you retire between 55 and 59½ and might need TSP money, rolling to an IRA converts penalty-free withdrawals into penalized ones. Keep enough in the TSP to bridge those years.
Taking the entire balance in one taxable year
A single full withdrawal of a large traditional balance can push tens of thousands of dollars into the highest brackets and spike Medicare premiums. Spreading withdrawals across years almost always lowers lifetime tax.
Mistaking 20% withholding for the actual tax owed
The mandatory 20% is a prepayment, not your final bill. If your real bracket is higher, you'll owe more in April; if lower, you'll get it back. Plan for the true tax, not the withholding.
Inflation-adjusting withdrawals through a market crash
Mechanically raising your draw in a down year accelerates sequence-of-returns damage. The flexibility to trim installments is one of the TSP's best features — use it.
Ignoring the bracket-filling window before 73
The years between retirement and RMD age are the cheapest time to draw down or convert traditional dollars. Skip that window and RMDs plus Social Security can force you into higher brackets for the rest of your life.
Decision Framework
Before You Touch the Account, Answer These
What income gap does the TSP actually need to fill? Subtract your FERS annuity, the supplement, and Social Security from your spending. The TSP only has to cover the remainder.
Will I need money before 59½? If yes and you separated at 55+, keep enough in the TSP to use the age-55 rule rather than rolling it out.
Do I need independent control of traditional vs. Roth? If yes, plan around the proportional rule — possibly by moving the Roth slice to a Roth IRA.
How big will my traditional balance be at 73? If it's large, model drawdowns or Roth conversions in your 60s to soften the RMD and IRMAA hit later.
How will I protect the first decade? Decide your buffer (G Fund/cash) and your rule for trimming withdrawals in a downturn before you retire — not during the crash.
