For federal employees and members of the uniformed services, the Thrift Savings Plan can become one of the largest financial resources available in retirement.
Yet deciding what to do with your TSP is not as simple as choosing whether to leave the money where it is or move it somewhere else. Your decision can affect investment choices, fees, withdrawal flexibility, taxes, access to your money, and the income available to you throughout retirement.
The right strategy depends on the rest of your financial picture. Before making a major change, consider these seven decisions.
1. Decide What Role the TSP Will Play in Your Retirement
Before choosing investments or requesting a distribution, determine what you need the account to accomplish.
Your retirement income may come from several sources, including:
- A FERS or CSRS pension
- Social Security
- Your TSP
- A spouse’s pension or retirement accounts
- IRAs or other employer plans
- Taxable investments
- Cash savings
- Part-time employment
For some retirees, pension and Social Security income may cover most essential expenses, allowing the TSP to remain invested for future needs. Others may need regular TSP withdrawals to supplement monthly income immediately after retirement.
The TSP might also serve as a bridge while you delay Social Security, a reserve for healthcare or home expenses, a source of discretionary income, or an asset intended partly for heirs.
Defining its purpose helps determine how the account should be invested and how quickly money should be withdrawn.
2. Determine Whether to Stay in the TSP, Move the Money, or Use Both
Leaving federal service does not mean you must leave the TSP.
Participants can generally keep their savings in the plan after separating from federal employment. You can continue managing your investments and are not required to withdraw the entire balance simply because you retire.
Keeping money in the TSP may appeal to retirees who value its streamlined investment lineup and relatively low expenses. The plan offers five individual investment funds—the G, F, C, S, and I Funds—along with Lifecycle Funds that invest across those underlying choices.
An IRA, on the other hand, may offer a wider selection of investments and access to more personalized portfolio or income-management services. That additional flexibility may also come with advisory fees, account fees, or higher underlying investment expenses.
You do not necessarily have to make an all-or-nothing decision. Depending on TSP and receiving-account rules, it may be possible to retain part of the account while directly rolling another portion into an IRA or eligible retirement plan.
Before moving any money, compare:
- Total investment and advisory costs
- Investment options
- Withdrawal flexibility
- Access to professional guidance
- Creditor and legal protections
- Beneficiary and estate-planning features
- Early-retirement withdrawal rules
- The services you will actually use
A rollover should solve a planning need rather than simply follow a salesperson’s recommendation.
3. Reevaluate How the Account Is Invested
An investment allocation that worked during your career may not be appropriate once withdrawals begin.
During your working years, market declines may have been easier to tolerate because you were still contributing to the account. In retirement, selling investments during a downturn can make it more difficult for the portfolio to recover. This is commonly referred to as sequence-of-returns risk.
That does not necessarily mean moving the entire account into conservative investments. A retirement lasting 20 or 30 years may still require growth to help offset inflation.
Instead, consider dividing your needs by time horizon:
- Money needed soon may require greater stability.
- Money intended for later retirement may remain invested for growth.
- Funds intended for heirs may have an even longer investment horizon.
The TSP’s G Fund is designed to preserve principal while earning a rate based on specially issued U.S. Treasury securities. Other TSP funds involve varying levels of bond, domestic-stock, and international-stock exposure.
Your allocation should reflect when you expect to use the money—not merely your age or retirement date.
4. Select a Withdrawal Strategy Before the First Withdrawal
The TSP offers several ways to access retirement savings, including partial distributions, installment payments, a total distribution, and the purchase of a life annuity. Each approach provides a different balance of liquidity, control, and income predictability.
Partial distributions
A partial distribution can provide money for a specific need while allowing the remainder of the account to stay invested.
Installment payments
Installments can be used to create recurring income. The amount should be coordinated with pension income, Social Security, taxes, and the expected longevity of the account.
Total distribution
Taking the entire account at once may create a substantial tax bill if the distribution is not directly rolled into another eligible retirement account. It also removes the money from its existing tax-deferred environment.
Life annuity purchase
A TSP life annuity exchanges a portion of the account for guaranteed lifetime payments. Once the annuity is purchased, you no longer manage or control the money used for the purchase.
The objective is not simply to choose a withdrawal method. It is to design a retirement paycheck that can support current spending without unnecessarily reducing future flexibility.
5. Coordinate Traditional and Roth TSP Money
Traditional and Roth TSP balances receive different tax treatment.
Withdrawals from a traditional TSP balance are generally taxable as ordinary income. Qualified Roth TSP distributions can generally be received free from federal income tax when applicable requirements have been met.
Traditional TSP balances may eventually be subject to required minimum distributions after the participant reaches the applicable age and has separated from service. Roth TSP balances are not currently subject to lifetime RMDs for the original account owner.
This creates planning opportunities, especially during the years between retirement and the beginning of Social Security or required distributions.
TSP participants also gained access to Roth in-plan conversions in 2026. A conversion moves money from the traditional balance to the Roth balance and generally creates taxable income in the year of conversion. The potential long-term benefit must therefore be weighed against the immediate tax cost.
Before converting, consider how the additional income could affect:
- Your federal and state tax brackets
- Medicare income-related premium adjustments
- Taxation of Social Security benefits
- Available deductions and credits
- Cash available to pay the tax
- The surviving spouse’s future tax situation
A conversion is not automatically beneficial simply because tax-free income sounds attractive.
6. Protect Your Access to Money if You Retire Early
The timing of a rollover can be especially important for someone leaving federal service before age 59½.
Federal tax rules contain an exception to the additional 10% early-distribution tax for certain distributions from an employer retirement plan after separation from service during or after the calendar year in which the participant reaches age 55. Different or more favorable rules may apply to certain qualifying public-safety employees.
That separation-from-service exception generally applies to distributions from the employer plan—not to a later withdrawal from an IRA.
As a result, someone who expects to use TSP money before age 59½ should be cautious about immediately rolling the entire balance into an IRA. The rollover could unintentionally eliminate a useful way to access retirement savings without the additional early-distribution tax.
Before moving the account, identify:
- Your retirement date
- Your age in the year of separation
- When income withdrawals will begin
- Which account will provide those withdrawals
- Which tax exceptions may apply
Tax rules are complex, and eligibility should be reviewed with a qualified tax professional before taking a distribution.
7. Review Loans, Beneficiaries, and Account Administration
Administrative details can easily be overlooked during the transition out of federal service.
Before retiring, review any outstanding TSP loan and understand the current repayment and tax rules that will apply after separation. Also confirm that the TSP has your current address, banking information, email address, and beneficiary designation.
Your beneficiary choice should be coordinated with your will, trust, insurance policies, pension survivor election, and other retirement accounts.
Both spouses should also understand how the TSP fits into the household plan. The spouse who does not normally manage the finances should know how to access important records, whom to contact, and how the account is intended to support the surviving spouse.
Questions to Ask Before Making a TSP Decision
Before retiring or requesting a rollover, consider:
- How much monthly income will my pension and Social Security provide?
- When will I need to begin using the TSP?
- Am I comfortable managing the account myself?
- How do TSP expenses compare with the proposed alternative?
- Do I need investments or planning services unavailable within the TSP?
- Will I need access to the money before age 59½?
- What are the tax consequences of traditional withdrawals or Roth conversions?
- Is my current investment allocation appropriate once withdrawals begin?
- Are my beneficiary instructions current?
- How would the plan change after the death of either spouse?
Final Thoughts
Your TSP decision should be part of a complete federal-retirement strategy—not an isolated rollover decision.
The best approach may involve keeping the account in the TSP, moving it to an IRA, using a combination of both, or gradually changing the strategy as retirement progresses.
