Roth TSP and RMDs After SECURE 2.0: What Changed and Why It Matters for Foreign Service Retirees

Foreign Service Money Matters

For years, Foreign Service officers and other federal employees with Roth TSP balances faced an awkward planning quirk: their Roth TSP — money they'd already paid tax on, now growing tax-free — was nonetheless subject to required minimum distributions in retirement. That single difference made many advisors reflexively recommend rolling Roth TSP balances into Roth IRAs as soon as possible, just to escape the RMD requirement.

The SECURE 2.0 Act of 2022 changed this. As of 2024, lifetime RMDs from Roth TSP accounts are eliminated. The change brings Roth TSP into alignment with Roth IRA treatment during the owner's lifetime — and it meaningfully shifts how FSOs should think about Roth conversion strategy, TSP rollover decisions, and retirement income sequencing.

Here's what changed, what didn't, and what it means for your planning.

The old rule

Before SECURE 2.0, Roth TSP was treated like other designated Roth accounts in employer plans (Roth 401(k), Roth 403(b)). Even though contributions were after-tax and qualified withdrawals were tax-free, the IRS required participants to begin taking distributions at age 73 — the same Required Beginning Date (RBD) that applies to traditional retirement accounts.

This created two problems for FSOs:

  • Forced erosion of tax-free growth. Every dollar you were required to withdraw was a dollar no longer compounding tax-free inside the account.
  • Unnecessary planning complexity. Many participants rolled Roth TSP to Roth IRA simply to escape the RMD rule, even when the TSP's investment options and low costs would otherwise have been preferable.

The standard workaround — roll Roth TSP to Roth IRA before age 73 — worked, but it required action, paperwork, and forfeiting access to the TSP G Fund (a meaningful loss for retirees who valued its non-marketable structure).

What SECURE 2.0 changed

Section 325 of SECURE 2.0 eliminated the RMD requirement for designated Roth accounts in employer plans during the participant's lifetime. The change applies to Roth TSP, Roth 401(k), and Roth 403(b) accounts. It is effective for taxable years beginning after December 31, 2023 — meaning 2024 was the first year participants were no longer required to take RMDs from these accounts.

The change is permanent and does not phase out. It does not affect traditional TSP balances, which remain subject to RMDs at age 73 (rising to 75 for those born in 1960 or later under SECURE 2.0).

The practical effect: a Foreign Service retiree with Roth TSP can now leave the balance in place and let it grow tax-free for the remainder of their lifetime, drawing on it only when needed.

What didn't change

Two important caveats:

  • Beneficiary RMDs still apply. Once the original participant dies, the inherited Roth TSP is subject to the SECURE Act's beneficiary distribution rules. Most non-spouse beneficiaries — including adult children — must fully distribute the account within 10 years of the original owner's death. The lifetime exemption applies only to the participant, not to heirs.
  • The qualified distribution rules are unchanged. To withdraw earnings tax-free from Roth TSP, you still need to satisfy the 5-year holding rule and be 59½ or older. Contributions can always be withdrawn tax-free, but earnings have separate timing rules. Foreign Service officers approaching retirement should verify when their first Roth TSP contribution was made — the 5-year clock starts then, and it does not transfer cleanly to an IRA on rollover.

Should you still roll Roth TSP to a Roth IRA?

For many FSOs, the historic case for rolling Roth TSP out at retirement was driven primarily by the RMD problem. With that gone, the calculus shifts. Reasons to keep Roth TSP in place now include:

  • Continued access to the G Fund. No private-sector account offers a comparable instrument.
  • Low expense ratios. TSP costs remain among the lowest available anywhere.
  • Creditor protection. TSP balances enjoy strong federal protection against creditors that may exceed what's available in IRAs depending on your state of residence.
  • Simpler estate planning during your lifetime. Fewer accounts, fewer beneficiary forms.

Reasons to still consider a rollover include:

  • Investment flexibility. TSP's lineup is intentionally narrow. If you want exposure to factors, sectors, or asset classes outside the core funds, an IRA is the only path.
  • Withdrawal flexibility. TSP withdrawals are more rigid than IRA withdrawals, particularly for partial distributions and pro-rata rules between traditional and Roth balances.
  • Beneficiary planning. Certain trust-as-beneficiary strategies are easier to administer in an IRA than in TSP.
  • Roth conversion source planning. Some retirees use IRAs as conversion vehicles where TSP rules wouldn't accommodate.

There is no universally correct answer. The decision should be made based on your full retirement income plan, your investment philosophy, your estate goals, and your appetite for account simplification.

What this means for Roth conversion strategy

For FSOs in the years leading up to retirement and the early retirement years before Social Security and the FSPS Annuity Supplement begin reducing in importance, Roth conversions remain a central planning tool. The SECURE 2.0 change does not eliminate the case for converting traditional balances to Roth — but it does eliminate one of the reasons FSOs sometimes hesitated to build large Roth TSP balances during their careers.

If you've been making mostly Traditional TSP contributions out of concern about future RMDs from a Roth TSP, that concern is obsolete. Roth TSP now functions as a true tax-free retirement bucket without the lifetime distribution requirement that previously distinguished it from a Roth IRA.

Planning takeaways

The SECURE 2.0 change to Roth TSP is one of the clearer wins for federal employees in recent retirement legislation. It simplifies planning, removes a forced erosion of tax-free growth, and eliminates a key reason FSOs felt obligated to roll out of TSP at retirement. The downstream implications — Roth conversion strategy, withdrawal sequencing, beneficiary planning, and the in-or-out TSP rollover decision — are worth revisiting in light of the new rules, especially for officers within five years of retirement who may have planned around the old framework.
