Best Annuities for TSP Rollover

At Diversified Insurance Brokers, we work with federal employees, uniformed service members, and civilians leaving government service who are navigating one of the most consequential financial decisions in their retirement transition: what to do with a Thrift Savings Plan account when they separate from service. The TSP is a genuinely excellent retirement savings vehicle while you are employed — among the lowest-cost institutional plans available anywhere in the United States. But the moment you separate from federal service, the TSP’s relative strengths begin competing with the private marketplace’s strengths, and the correct decision is not automatically one or the other. It depends entirely on your goals: whether you want guaranteed declared-rate growth, protected index-linked accumulation, or guaranteed lifetime income. This guide covers the best annuity options for a TSP rollover, organized by planning objective rather than by product type, so the decision framework starts with your needs rather than with a product recommendation.  Working with us gives you access to an Independent Annuity Broker, meaning we shop the entire market, not just a select few carriers.

Understanding the full pros and cons of annuity structures is the starting point before any TSP rollover evaluation — because rolling into an annuity is one of four broad options available to a separated TSP participant, not the only option or automatically the best one. The four options are: keep the balance in the TSP, roll over to an IRA and self-direct the investments, roll over to a new employer plan (if your next employer’s plan accepts incoming rollovers), or roll over to an IRA and fund an annuity contract. Each has distinct advantages and limitations, and the TSP’s own built-in options — particularly the G Fund — have characteristics that genuinely cannot be replicated in the private market. Acknowledging those characteristics honestly is the foundation of a complete TSP rollover evaluation rather than a reflexive recommendation in either direction.

For the federal employees, military members, and civil servants reading this: the annuity options covered in this guide span the full planning spectrum. A Multi-Year Guaranteed Annuity (MYGA) provides declared-rate certainty comparable to what the TSP’s G Fund offers, but with longer rate-lock periods (up to 10 years), full tax deferral, and access to the competitive private marketplace’s declared rates. A Fixed Indexed Annuity (FIA) provides principal protection with market-linked growth potential — participating in index gains subject to caps or participation rates while guaranteeing that market declines do not reduce your account value. And a lifetime income annuity — whether a Single Premium Immediate Annuity (SPIA) or a Deferred Income Annuity (DIA) — converts your accumulated TSP balance into a guaranteed monthly income stream for life, addressing the longevity risk that the TSP’s investment-based options cannot resolve by themselves. Which of these, if any, is the right destination for your TSP balance depends on the specifics of your retirement plan — and this guide covers the analytical framework for evaluating each option clearly.

What Makes the TSP Unique — and Why the Rollover Decision Deserves Careful Analysis

Before evaluating any annuity option, every TSP participant should understand two features of the TSP that genuinely cannot be replicated in the private marketplace: the G Fund and the expense ratio structure. Both are legitimate reasons to consider keeping some or all of your TSP balance in the plan even after separation, and no honest TSP rollover evaluation should proceed without acknowledging them.

The G Fund — Government Securities Investment Fund — is unique among all retirement savings vehicles available to American investors. Unlike a traditional money market fund or short-term bond fund, the G Fund invests exclusively in specially issued non-marketable U.S. Treasury securities. What makes it distinctive is the rate it earns: by law, the G Fund receives the weighted average yield of all outstanding U.S. Treasury notes and bonds with more than four years to maturity — effectively earning a long-term bond rate. But it does so with the liquidity and principal protection of a short-term instrument. There is no credit risk, no interest rate risk to principal, and no possibility of negative return in any period. The G Fund rate adjusts monthly based on the prevailing Treasury yield environment. This combination — long-term rates with short-term safety — is not available anywhere in the private market at any price. There is no MYGA, CD, money market fund, or stable value fund outside the TSP that replicates it. If the G Fund is a significant portion of your TSP allocation and its characteristics are important to your retirement plan, that is a meaningful argument for keeping at least a portion of your balance in the TSP rather than rolling the full amount out.

The TSP’s expense ratios are among the lowest of any institutional retirement plan in the country. While specific expense ratios change annually and are published on tsp.gov (flag: verify current figures at tsp.gov before citing), they have historically been a small fraction of what comparable mutual funds charge in the private marketplace. For participants whose primary objective is low-cost equity market exposure during accumulation, the TSP’s C Fund (tracking the S&P 500) and S Fund (tracking small- and mid-cap stocks) provide that exposure at institutional pricing that private market alternatives rarely match. The rollover decision should acknowledge this: when you move TSP assets into a private-market product, you are trading the TSP’s extraordinary cost efficiency for other benefits — guaranteed rates, principal protection, income guarantees, or planning flexibility — that the TSP does not provide. The trade-off is legitimate and often correct, but it should be acknowledged explicitly rather than glossed over in the rollover process.

Annuity Options for TSP Rollover — Side-by-Side Comparison

MYGA After TSP Rollover — Declared-Rate Certainty in the Private Market

A Multi-Year Guaranteed Annuity is the closest private-market equivalent to what the TSP’s G Fund provides conceptually — a defined, contractually guaranteed interest rate with full principal protection — but with several structural advantages that the G Fund cannot offer. The most significant is the rate-lock period. The G Fund’s rate adjusts monthly based on the prevailing Treasury yield environment, meaning the effective rate you earn on your G Fund balance changes continuously and cannot be locked in for a defined future period. A MYGA locks a declared rate for the full 3, 5, 7, or 10-year guarantee period at purchase, regardless of how the interest rate environment moves during that time. In a declining rate environment, the MYGA’s locked rate continues compounding at the original declared level while the G Fund’s monthly rate falls with the Treasury market.

The competitive MYGA marketplace — across 75+ carriers at multiple rating tiers — means that declared rates in the private market often compare favorably to the G Fund’s prevailing rate, particularly at the 5- to 10-year term lengths where the MYGA’s options budget can be allocated more generously. For TSP participants who have been using the G Fund as their primary safe-money allocation and are separating from service, a MYGA with a competitive 5- or 7-year declared rate from an A-rated carrier provides: the same principal protection (backed by carrier financial strength and state guaranty association protections); full tax deferral during the guarantee period (identical to the G Fund’s tax treatment within the TSP qualified wrapper); 10% annual free withdrawals for liquidity (most G Fund participants use annual distributions rather than full surrenders); and the flexibility to reposition at maturity into a new MYGA, an FIA, or an income annuity based on market conditions at that time. A MYGA laddering strategy — splitting the rollover across 3-year, 5-year, and 7-year MYGA contracts simultaneously — replicates the TSP’s installment distribution flexibility while capturing competitive declared rates across the full yield curve.

Carriers like Gainbridge Life have built MYGA products specifically optimized for IRA rollover efficiency, with digital-first application processes that can make the TSP-to-IRA-to-MYGA pathway straightforward for federal employees who prefer a streamlined execution. When evaluating any MYGA for a TSP rollover, the carrier’s AM Best financial strength rating is the most important due diligence variable — the declared rate guarantee is only as strong as the carrier’s ability to fulfill it, and an A- or higher AM Best rating is the standard most conservative financial planners apply before placing retirement rollover assets.

Fixed Indexed Annuity After TSP Rollover — Protected Growth Beyond G Fund Returns

A Fixed Indexed Annuity addresses a specific and common dissatisfaction that many TSP participants have with the G Fund: it is safe but it is not growing at the rate needed to keep up with inflation or to build meaningful additional retirement assets. The C Fund and S Fund do provide market-level growth, but with full equity downside risk — not suitable for the portion of a federal employee’s retirement assets that needs to be protected from sequence-of-returns risk near or in retirement. The FIA fills the gap between the G Fund’s safety-without-growth and the C/S Fund’s growth-without-safety. For the portion of your TSP rollover that needs to grow beyond G Fund rates but cannot afford the C/S Fund’s full market exposure, an FIA provides: the 0% floor that prevents market-caused principal loss; index-linked growth potential through S&P 500, Nasdaq-100, or volatility-controlled index strategies in positive market years; full tax deferral identical to the TSP’s qualified wrapper; and the 10% annual free withdrawal provision for liquidity during the surrender period.

The sequence-of-returns risk context is particularly relevant for federal employees who are transitioning from accumulation to distribution: you are at exactly the point in the retirement timeline where a severe market drawdown in the early years of retirement does the most permanent damage to portfolio sustainability. An FIA protects the portion of the rollover allocated to it from that specific risk — the early-retirement drawdown that is most destructive precisely because withdrawals are being taken from a declining portfolio. By allocating a meaningful portion of the TSP rollover to an FIA and leaving the remainder in market-exposed vehicles (either within the TSP in C/S/I Funds or in a self-directed IRA with equity funds), the federal retiree creates a protected floor allocation that does not need to be liquidated during market declines — allowing the market-exposed allocation to recover without the compounding damage of forced distributions.

Income Annuity After TSP Rollover — Building a Private Pension

For federal employees who participate in FERS rather than CSRS, the federal pension (FERS basic benefit) is typically more modest than the CSRS pension, and the TSP is intended to fill a larger portion of the retirement income need. For these participants — and for military members whose retirement income may not fully cover essential expenses — converting some or all of the TSP rollover into a guaranteed lifetime income stream through a Single Premium Immediate Annuity (SPIA) or Deferred Income Annuity (DIA) addresses longevity risk in a way that no investment-based strategy can replicate. A SPIA converts the rollover premium into monthly guaranteed income payments beginning immediately (typically within 30 days of purchase); a DIA defers the income start date — sometimes by years or even decades — allowing the income amount to be significantly higher at activation than a SPIA purchased at the same time for the same premium.

The income annuity is the only retirement vehicle that guarantees income for as long as you live regardless of how long that is — which is precisely the risk that federal retirees face that neither the G Fund nor the C Fund can address contractually. A FERS employee who retires at 62, collects Social Security at 67, and lives to 91 faces a 29-year retirement span. An income annuity purchased with a portion of the TSP rollover at retirement provides income across every one of those years — whether markets are strong or weak, whether interest rates rise or fall, whether the carrier’s portfolio outperforms or underperforms. For federal employees whose FERS pension plus Social Security does not fully cover essential monthly expenses, an income annuity sized to fill that specific gap creates a guaranteed income floor that removes the sequence-of-returns risk from the essential expense coverage entirely, leaving the remaining TSP and other assets to grow without distribution pressure.

TSP Rollover Mechanics — Direct vs. Indirect, Traditional vs. Roth

Understanding how to execute a TSP rollover correctly is as important as knowing which annuity to fund with the proceeds. The rollover mechanics are verified from TSP.gov and IRS Publication 721, and getting them wrong creates costly, sometimes irreversible tax consequences. A direct rollover — also called a trustee-to-trustee transfer — instructs the TSP to send your account balance directly to the receiving IRA custodian or plan administrator without the funds ever passing through your hands. In a direct rollover, no federal income tax is withheld, no 60-day reinvestment deadline applies, and the full amount of the distribution arrives at the destination account intact. This is the correct method for virtually all TSP rollover situations, and understanding how qualified plan transfers work mechanically — specifically the form completion, the receiving institution certification requirements, and the timeline — prevents the common errors that convert a tax-free transfer into a taxable distribution. An indirect rollover — where the TSP sends a check to you personally — triggers mandatory 20% federal income tax withholding on the taxable portion. You then have 60 days to deposit the full distribution amount (including the withheld 20%) into the receiving account. If you deposit only the 80% you received without replacing the withheld 20% from other sources, that 20% is treated as a taxable distribution — potentially plus the 10% early distribution penalty if you are under 59½. The indirect rollover is almost always the wrong method when a direct rollover is available.

The Traditional-to-Traditional and Roth-to-Roth matching rules are the second critical mechanic. A Traditional TSP balance rolled to a Traditional IRA is not a taxable event — the funds remain pre-tax and continue deferring taxes until distribution. A Roth TSP balance rolled to a Roth IRA is also not a taxable event. Converting a Traditional TSP balance to a Roth IRA is a taxable event — the full converted amount is added to ordinary income in the year of the conversion. This Roth conversion strategy can be appropriate in specific tax planning contexts (particularly in low-income years between retirement and Social Security activation), but it is a deliberate tax planning decision, not an inadvertent outcome. Outstanding TSP loans must be repaid before completing a full rollover — if an outstanding loan is not repaid before the distribution is processed, the loan balance is treated as a deemed distribution, which is taxable and potentially subject to the 10% penalty, and cannot be rolled over. Finally, married FERS and uniformed services participants with total TSP account balances over $3,500 who want to do a total withdrawal must obtain notarized spousal consent — their spouse is entitled by law to a joint life annuity with survivor benefits, and any other withdrawal option requires the spouse to formally waive that right.

RMDs, TSP-Specific Rules, and What You Give Up By Rolling Out

Several TSP-specific rules interact with the rollover decision in ways that many federal employees are not fully aware of. Required Minimum Distributions apply to traditional TSP accounts beginning at the required beginning date — the April 1 following the year the participant turns 73 (or 75 for those born in 1960 or later under SECURE 2.0). Unlike IRAs where the aggregation rule allows multiple IRA accounts’ RMDs to be satisfied from any one account, TSP RMDs must be taken from the TSP itself — the IRA aggregation rule does not apply to TSP accounts. Understanding how RMDs work under SECURE 2.0 — particularly the extended RMD ages, the modified penalty structure, and how Roth balances are treated — is part of the TSP rollover evaluation, because rolling the traditional TSP balance into a Traditional IRA makes the RMD subject to IRA aggregation rules (which can be more flexible for multi-account owners) while rolling into a qualified annuity requires that the annuity’s free withdrawal provision accommodate the RMD amount from that specific contract.

The G Fund access issue bears repeating as a permanent consideration: once assets leave the TSP, they cannot be returned. The TSP accepts incoming rollovers from IRAs and eligible employer plans, but the form specifying this — TSP Form TSP-60 — explicitly requires an open TSP account. Separated participants who have closed their TSP account by doing a full rollover cannot reopen it for a new rollover back in. If the G Fund’s characteristics become valuable to you after the rollover — perhaps in a future rising rate environment when the G Fund’s long-term rate with short-term safety looks attractive again — the option to access it within the TSP will no longer be available. This permanence is worth weighing explicitly in the rollover analysis rather than treating the rollover as reversible.
