What Should I do with my TSP after I Retire?

Federal employees and members of the U.S. military rely on the Thrift Savings Plan as a core retirement account — one of the largest defined-contribution plans in the world and one of the lowest-cost retirement vehicles available to American workers. But when retirement finally arrives, a significant question remains: what should you do with your TSP? Your TSP may represent decades of disciplined saving, and the decisions you make at retirement can shape your taxes, your income reliability, and how protected your household feels when markets are volatile. Before choosing a path, a solid overview of how the plan works helps frame the options: How Does a TSP Work?

Some retirees want maximum simplicity and low costs — keeping the TSP’s institutional expense ratios and familiar fund structure intact. Others want more control, more flexible withdrawal planning, and clearer income options. Many want a combination: keep some money invested for long-term growth while building a safety-and-income foundation so essential expenses are covered regardless of what happens with markets. The most important insight is that retirement is not an accumulation problem — it is an income and stability problem, and the TSP’s strengths during accumulation are not necessarily its strengths in distribution. For most federal retirees whose TSP must help cover essential monthly expenses, rolling at least a portion into a fixed or fixed indexed annuity is the most direct solution to the income certainty problem the TSP alone cannot solve.

TSP Retirement Options Compared — What Each Path Delivers

Before examining each option in depth, the table below maps the primary TSP distribution paths against what each one provides, its primary risk, and the planning priority each one serves.

What Happens to a TSP When You Retire

Retirement does not force you to close your TSP. You can leave your money inside the plan, keep the same fund allocations, and continue managing investment choices — the account simply shifts from accumulation to distribution mode. That shift matters because the biggest retirement risk is not the long-term average return. It is whether the plan produces dependable income and keeps you from being forced to sell assets after a market decline during years when you are also withdrawing for living expenses.

In retirement, most TSP participants evaluate three broad directions: keep the account in the TSP for its low costs and G Fund access, roll it to an IRA for flexibility, or move part or all of the balance into guaranteed solutions designed to create pension-like income and protect principal. One important tax nuance: RMD amounts from the TSP cannot be rolled over — the required minimum distribution for the year must be taken and taxed before any rollover of the remaining balance can proceed. Under SECURE 2.0, RMDs from a traditional TSP begin at age 73 (or 75 for those born in 1960 or later). Roth TSP balances are no longer subject to RMDs during the owner’s lifetime, matching the Roth IRA treatment — which gives retirees who have Roth balances more flexibility in the distribution timeline.

Option 1: Leave Your Money in the TSP

Keeping the balance in the TSP can be appropriate — particularly for retirees who have strong guaranteed income from other sources (FERS pension, CSRS pension, or Social Security) and don’t depend on the TSP to cover essential monthly costs. The TSP’s institutional expense ratios are among the lowest available for any retirement account, and the G Fund — a unique government securities fund that provides interest income without market risk — has no direct equivalent outside the federal plan. For retirees who value the G Fund specifically, keeping at least a portion of assets inside the TSP preserves access to that feature.

The trade-off is design limitation. The TSP investment menu is deliberately narrow — five core fund options plus lifecycle funds — and there are no private-market income rider solutions that allow you to design a contractual lifetime paycheck while maintaining account-level control. Many retirees also want clearer legacy outcomes, more flexible beneficiary designation mechanics, or the ability to activate income at a time of their choosing — flexibility that the TSP’s distribution structure does not fully provide. For retirees who keep the TSP, the practical best practice is treating it as the “growth bucket” while building a separate guaranteed income base elsewhere. That separation is what keeps essential expenses protected from the market’s timing variability.

Option 2: Roll the TSP Into a Traditional IRA

A direct rollover from the TSP to a traditional IRA keeps the money tax-deferred and expands the investment and planning options available. Direct rollover — trustee to trustee — avoids the mandatory 20% withholding that applies when a TSP distribution is taken directly by the account holder, and avoids the 60-day redeposit deadline that creates costly errors when retirees attempt an indirect rollover. A Roth TSP rollover to a Roth IRA preserves the tax-free treatment and eliminates RMDs during the owner’s lifetime that would apply to the Roth TSP under the plan’s own rules — which is itself a meaningful benefit for many federal retirees.

Rolling to a traditional IRA expands the menu of fixed, indexed, and income annuity options available within the IRA wrapper — which is the primary reason many federal retirees use the IRA rollover as the gateway to a fixed or fixed indexed annuity strategy rather than as the destination itself. The rollover is the correct first step; the allocation into a principal-protected structure is the correct second step. A traditional IRA that remains invested in equity funds does not solve the income certainty problem — it simply moves the same market exposure to a different container.

Option 3: Transfer TSP to a Fixed or Fixed Indexed Annuity — The Income Foundation Strategy

For federal retirees whose TSP must support essential living expenses — and who do not have a pension large enough to cover those costs from the FERS base alone — rolling part or all of the TSP into a fixed or fixed indexed annuity is the most direct solution available. The transfer is executed as a direct rollover into a qualified annuity, preserving full tax deferral with no current tax event and no withholding risk. Once inside the qualified annuity, assets continue to grow tax-deferred — future distributions are taxed as ordinary income in the year received, exactly as they would have been from the original TSP, so the tax treatment is unchanged while the risk profile and income predictability improve substantially.

A fixed MYGA strategy locks in a declared interest rate for the full term — typically 3 to 10 years — with no possibility of principal loss due to market performance. A fixed indexed annuity adds index-linked growth potential: in positive index years a portion of the gain is credited; in negative years credited interest is 0% and the principal is fully protected. With an optional Guaranteed Lifetime Withdrawal Benefit rider, the annuity creates a guaranteed lifetime paycheck that cannot be outlived — a personal pension supplement that addresses the gap many federal retirees face if FERS alone does not fully cover essential expenses. The complete step-by-step transfer process is covered in our dedicated resource: How to Transfer a TSP to an Annuity. For context on how this same income design concept applies to annuities broadly: How Does a Fixed Indexed Annuity Work?

Most retirees don’t move the entire TSP balance into an annuity. Instead, they reposition the portion that must cover essential monthly expenses into the principal-protected structure, then keep remaining assets in more flexible investments for discretionary spending and growth. This “floor-and-flex” design consistently produces the most sustainable and psychologically resilient retirement income structure.

Option 4: TSP Annuitization vs. Private-Market Annuity Options

The TSP’s internal annuity option converts a portion of the TSP balance into a lifetime income stream through the plan’s designated annuity provider. The key limitation is that this purchase is irrevocable — once the TSP annuity is purchased, it cannot be changed, cancelled, or unwound, even if your needs or circumstances change significantly after the fact. The TSP is also explicit about this on its website: the annuity purchased through the plan is no longer part of the TSP account, and the flexibility that characterized the TSP during accumulation is gone entirely at the moment of purchase.

Because of that irrevocability and limited design flexibility, most federal retirees who want guaranteed lifetime income compare private-market fixed indexed annuity designs before committing to the TSP’s internal option. Private-market FIAs typically offer more design control — including optional liquidity provisions within the surrender schedule, clearer beneficiary and death benefit outcomes, income rider structures that can be activated later rather than immediately, and the ability to pass remaining account value to heirs if the annuitant dies before exhausting the contract. Understanding what annuity fees look like across different contract designs helps evaluate whether the trade-off between cost and feature access makes sense for a specific household’s priorities.

Option 5: Cash Distributions — When They Make Sense and When They Don’t

TSP withdrawals from traditional (pre-tax) balances are taxed as ordinary income in the year received. A large distribution can push a retiree into a significantly higher tax bracket, trigger Medicare premium surcharges under IRMAA, and increase the taxable portion of Social Security benefits — effects that can compound across multiple years if not managed deliberately. Losing the tax-deferred wrapper also permanently eliminates the benefit of sheltered compounding on the distributed amount. This does not mean distributions are wrong — it means they should be intentional and sequenced. Many federal retirees coordinate withdrawals across multiple sources (TSP, IRA, taxable accounts, Social Security timing) so total taxable income stays as predictable and tax-efficient as possible year to year. For the full RMD mechanics and timing rules: required minimum distributions and RMDs after SECURE 2.0.

How to Build a Three-Bucket TSP Retirement Strategy

The most practical framework for TSP retirement decisions is matching each dollar to the role it needs to play. A growth bucket — market-exposed investments for long-term upside — is appropriate for assets not needed for income in the near or medium term. A safety bucket — principal-protected fixed or indexed annuity — handles essential expenses that cannot be interrupted by market volatility. An income bucket — GLWB-equipped FIA, SPIA, or structured withdrawal strategy — produces the predictable cash flow that essential monthly costs require. The cleaner the assignment of dollars to roles, the more stable the retirement plan feels during market volatility, healthcare events, or other unexpected circumstances. Avoiding the outcome of not running out of money in retirement is not about predicting market performance — it is about ensuring essential income doesn’t depend on market performance. Our resource on how to not run out of money in retirement covers this framework in the context of retirement income planning broadly.
