For most federal retirees, the question isn’t whether the TSP or an IRA is better in theory; it’s which one serves your specific retirement better in practice. The honest answer is that both have real strengths, and for many retirees, the smartest move isn’t choosing one over the other.
The Case for Rolling to an IRA
The TSP is an excellent accumulation vehicle. As a distribution vehicle in retirement, it starts to show its limitations.
Beneficiary rules are the biggest limitation. When a non-spouse inherits TSP assets, the distribution requirements can trigger a significant and sudden tax burden. An inherited IRA generally allows beneficiaries to stretch distributions over up to ten years, creating meaningful tax planning flexibility. For retirees with children or other non-spouse beneficiaries, this difference alone can be worth tens of thousands of dollars.
Tax withholding is another friction point. The TSP mandates 20% federal withholding on many distributions and doesn’t allow state income tax withholding at all. An IRA lets you control both, which simplifies retirement tax planning considerably.
IRAs also open the door to Qualified Charitable Distributions, a powerful strategy for retirees 70½ or older who give to charity. QCDs allow charitable gifts directly from an IRA, excluded from taxable income, and can satisfy RMD requirements. The TSP offers no equivalent.
Finally, an IRA can hold an annuity with a lifetime income rider, giving retirees guaranteed income with far more flexibility than the TSP’s rigid annuity option through its contracted provider.
The Case for Staying in the TSP
The TSP’s expense ratios are among the lowest of any retirement account in existence, around 0.04% annually. Most IRA investors, even those using index funds, will pay more. Over a 20-year retirement, that fee gap compounds in ways that matter.
The G Fund is genuinely unique. It provides returns similar to intermediate-term Treasury securities with no principal risk, meaning the share price never goes down. Nothing like it exists in the IRA universe.
And for federal retirees under age 59½, the TSP’s penalty-free access starting at age 55 is a significant and often underappreciated advantage. IRA owners generally must wait until 59½ or set up 72(t) distributions, which are restrictive and inflexible.
The Smarter Frame
This decision doesn’t have to be binary. Many federal retirees are best served by a hybrid approach — keeping a portion in the TSP to preserve G Fund access and penalty-free withdrawal flexibility, while rolling the remainder into an IRA for better beneficiary planning, tax control, and income strategy options.
The right split depends on your age, income needs, family situation, and broader retirement plan, which is exactly why this conversation is worth having with a Federal Retirement Consultant (FRC®) before you make a move.
