The Roth TSP Advantage for Young Federal Employees

In the constantly changing field of retirement planning, federal employees encounter important decisions that can profoundly influence their financial future. One such decision revolves around choosing between traditional and Roth retirement plans, particularly within the framework of the Thrift Savings Plan (TSP). For younger federal employees, the math undeniably favors the Roth TSP, ushering in a new era of strategic financial planning.

Evolution of Retirement Plans

The genesis of qualified retirement plans, including the traditional TSP, dates back to the 1980s, built on the straightforward concept of setting aside a portion of one’s paycheck to secure a tax break in the current year. However, over the past 18 years, a compelling alternative has emerged, offering a unique approach to tax-favored savings—the Roth TSP. Established in 2012, the Roth TSP operates on the premise of forgoing the immediate tax break, opting instead for future tax benefits.

Distinguished by after-tax salary contributions and tax-free growth over time, the Roth TSP shares similarities with the Roth IRA. However, it surpasses the Roth IRA for federal employees in two crucial aspects. Firstly, federal employees can contribute more annually to the Roth TSP than to a Roth IRA. Secondly, while Roth IRA contributions are subject to adjusted gross income (AGI) limitations, the Roth TSP has no such income constraints.

Complexity for Financial Gain

Despite the complexity introduced by the Roth TSP, its unique features create opportunities for federal employees to strategically reduce lifetime tax bills and leave a more substantial financial legacy for themselves and their beneficiaries.

Crucially, understanding that tax-free qualified Roth TSP withdrawals can supplement taxable income becomes paramount for employees and retirees. This strategic move becomes especially valuable when federal retirees face the prospect of higher federal and state income brackets. Starting January 1, 2024, the Roth TSP gains a distinct advantage as it becomes exempt from required minimum distributions (RMD), contrasting with the traditional TSP’s obligatory distributions. This exemption allows the Roth TSP to remain intact for beneficiaries who can then enjoy tax-free withdrawals. However, non-spousal TSP beneficiaries must withdraw inherited Roth accounts within 10 years following the participant’s demise.

Strategic Contribution Choices: Traditional TSP vs. Roth TSP

Understanding when to contribute to the traditional TSP versus the Roth TSP is crucial for optimizing financial outcomes.

• Traditional TSP Contributions: Federal employees in their peak earning years, particularly those in the 35% or 37% federal income tax marginal brackets, benefit significantly from contributing to the traditional TSP. The immediate tax savings are particularly advantageous during the contribution phase.
• Shifting to Roth TSP: High-earning federal employees are advised to explore ways to channel funds into Roth accounts, such as Roth IRAs, when transitioning into a lower federal marginal tax bracket. Retirement, especially around age 60 or the minimum retirement age (MRA), presents a strategic window. At this juncture, direct transfers from the traditional TSP to a traditional IRA, followed by a conversion to a Roth IRA, can yield overall tax savings.

Strategic Considerations for Roth TSP Contributions

Determining when to contribute to the Roth TSP involves careful consideration of individual circumstances:

• Stable Tax Rates in Retirement: If an employee’s combined federal and state tax rates are expected to remain stable, the Roth TSP can still be a winning strategy due to its inherent flexibility.
• Anticipating Tax Rate Increases: Federal retirees should factor in the scheduled expiration of the tax cuts enacted in 2017. The potential reversion to pre-TCJA tax rates, adjusted for inflation after December 31, 2025, might place some retirees in higher federal marginal tax brackets.
• Legacy Planning: The Roth TSP gains significance for those desiring to bequeath their entire account to heirs. With RMD exemptions starting January 1, 2024, the Roth TSP can be passed on “intact,” offering a tax-efficient legacy.
• Spousal Protection: Married couples find a compelling argument for contributing to the Roth TSP. Unlike traditional TSPs subject to RMDs, the Roth TSP, starting January 1, 2024, provides a shield against mandatory distributions, safeguarding surviving spouses from potential higher federal marginal tax brackets.

The Hybrid Approach: Contributing to Both TSPs

Contributing to both the traditional TSP and the Roth TSP enables employees to hedge their bets. With a law set to take effect on January 1, 2026, federal employees aged 50 and older, with Social Security wages exceeding $145,000, will be required to contribute solely to the Roth TSP, underscoring the increasing importance of this savings vehicle.

In conclusion, the Roth TSP emerges as a powerful tool for younger federal employees keen on optimizing their retirement savings. By aligning contributions with their unique financial circumstances, federal workers can not only reduce their lifetime tax burden but also secure a more prosperous financial future for themselves and their beneficiaries. As the retirement landscape continues to evolve, staying informed about these options remains crucial for making the best choices for long-term financial success.
