For most federal retirees, the real question isn’t whether the TSP or an IRA is better in theory; it’s which one works better for your retirement in practice. The truth is, both have meaningful advantages, and in many cases, the most effective strategy isn’t choosing one over the other.
The Case for Rolling to an IRA
The TSP is an outstanding accumulation vehicle, but it can become more restrictive when it comes to distributions in retirement.
One of the biggest limitations is how beneficiary rules are handled. When a non-spouse inherits TSP assets, distribution requirements can create a sizable and immediate tax burden. In contrast, an inherited IRA typically allows distributions to be spread over as long as ten years, offering far more flexibility for tax planning. For retirees with children or other non-spouse beneficiaries, this difference alone can translate into substantial tax savings.
Tax withholding is another consideration. The TSP requires a mandatory 20% federal withholding on many distributions and does not allow for state tax withholding. IRAs provide significantly more control, allowing retirees to better align withdrawals with their overall tax strategy.
IRAs also enable Qualified Charitable Distributions (QCDs), a valuable tool for retirees age 70½ and older who give to charity. QCDs allow funds to be transferred directly from an IRA to a qualified charity, excluded from taxable income, and counted toward required minimum distributions. The TSP does not offer a comparable option.
Finally, IRAs provide access to a broader range of income strategies, including annuities with lifetime income riders—offering more flexibility than the TSP’s limited annuity option through its single provider.
The Case for Staying in the TSP
The TSP’s low cost structure is one of its strongest advantages. With expense ratios around 0.04%, it remains one of the most cost-efficient retirement plans available. Even low-cost IRA portfolios often come at a higher price, and over a multi-decade retirement, those differences can compound meaningfully.
The G Fund is another unique benefit. It offers returns comparable to intermediate-term Treasury securities while eliminating principal risk—meaning the share price does not fluctuate. There is no direct equivalent available in the IRA marketplace.
Additionally, for retirees who separate from service at or after age 55, the TSP allows penalty-free withdrawals—a significant advantage. IRA withdrawals generally incur penalties before age 59½ unless structured under more restrictive rules, such as 72(t) distributions.
A More Practical Approach
This decision doesn’t need to be all-or-nothing. Many federal retirees benefit from a hybrid strategy—keeping a portion of their assets in the TSP to retain access to the G Fund and early withdrawal flexibility, while rolling the remainder into an IRA for greater control over taxes, beneficiary planning, and income options.
The right balance depends on your age, income needs, family dynamics, and overall retirement strategy, which is why it’s a conversation worth having with a Federal Retirement Consultant (FRC®) before making any changes.
