Roth Conversions Explained for Federal Retirees: Myths vs Facts in 2026

Introduction

Roth conversions continue to attract interest among federal retirees, especially as 2026 brings changes to tax regulations that could affect retirement planning. Knowing how these conversions work, what federal rules apply, and separating persistent myths from facts can help you make informed decisions about your TSP and IRA accounts. By reading further, you’ll gain clarity on federal retirement tax rules—and get the facts you need to navigate this evolving landscape.

What Is a Roth Conversion?

A Roth conversion is a process where you transfer dollars from a traditional retirement account, such as a Thrift Savings Plan (TSP) or IRA, into a Roth account. When you convert, the amount you move is treated as taxable income in the year of conversion, but once in the Roth account, your future qualified withdrawals can be income-tax free under IRS rules. For federal retirees, Roth conversions are relevant because they influence how your retirement income is taxed, how you access your savings, and the long-term flexibility of your retirement plan.

Within the federal context, you may face some restrictions unique to federal programs. For instance, while the traditional TSP does not offer a direct, in-plan conversion to a Roth TSP, you can roll your TSP funds into a Roth IRA upon separation from service. Understanding these avenues is key to managing your federal retirement resources.

Why Do Federal Retirees Consider Roth Conversions?

Many federal retirees look at Roth conversions to help diversify their retirement savings and to gain more financial flexibility. By moving money from a tax-deferred source (like a traditional TSP or IRA) to a Roth account, you pay taxes now with the hope of reducing taxable income later, especially during required minimum distribution (RMD) years.

Some reasons federal retirees consider Roth conversions include:

• Tax diversification: Balancing accounts that are taxed differently offers more control over your taxable income in retirement.
• Potential for lower long-term taxes: Especially if you expect higher tax rates in the future due to policy changes or personal circumstances.
• Elimination of RMDs (for Roth IRAs): While Roth IRAs do not require RMDs during your lifetime, other accounts (such as the Roth TSP) currently do for retirees.

Federal retirement rules allow eligible participants to roll funds from the TSP to a Roth IRA after separating from federal service, creating additional ways to manage your taxes and withdrawals.

How Are Roth Conversions Treated Under Federal Rules?

To convert TSP or traditional IRA funds into a Roth account, you’ll follow a step-by-step process set by federal regulations:

1. TSP participants must first separate from federal service to move their TSP balance to a Roth IRA, since in-plan Roth conversions are not permitted in the traditional TSP.
2. Initiate a rollover: Official TSP procedures require you to request a direct rollover to a Roth IRA provider, documented through Form TSP-70 (for full withdrawals) or TSP-77 (for partial withdrawals).
3. IRA conversions: Converting a traditional IRA to a Roth IRA involves working directly with your IRA provider, reporting the transaction on IRS Form 8606.

Official guidance comes from the Office of Personnel Management (OPM), TSP.gov, and the IRS. The IRS confirms that converted amounts are fully subject to income tax the year you convert, but not to early withdrawal penalties, provided funds are moved properly. The TSP follows OPM guidelines and restricts in-plan conversions, focusing on rollovers post-separation. All program details must align with current federal statutes and published agency guidance.

What Are Common Myths About Roth Conversions?

Myth and misunderstanding surround Roth conversions, especially among retirees. Common myths include:

• “All retirees should convert to Roth accounts.” In reality, conversions are not universally beneficial. The choice depends on your income, tax bracket, and individual goals, as emphasized by resources from OPM and the IRS.
• “Roth conversions eliminate required minimum distributions (RMDs) for all accounts.” Only Roth IRAs are immune from RMDs for original owners. The Roth TSP and inherited Roth accounts still have RMDs, according to TSP.gov and federal law.
• “No taxes are due on conversions if you’re retired.” Any amount you convert from a tax-deferred account is generally counted as ordinary income in the year of conversion, regardless of your employment status.
• “Converting means all future withdrawals are tax-free.” While qualified Roth withdrawals are tax-free if time and age requirements are met, early or non-qualified distributions could still face taxes or penalties.

Clarifying these myths using only federal documentation and published rules ensures you receive accurate, unbiased information.

What Are the Facts on Roth Conversions for Retirees?

Here are essential facts for federal retirees regarding Roth conversions:

• Taxable event at the time of conversion: Any converted amount is taxed as ordinary income the same year, as required by the IRS.
• No penalties if done properly: If you complete the process via direct rollover and follow all federal rollover rules, you avoid the 10% early withdrawal penalty, regardless of age.
• RMDs still apply to Roth TSPs: The Roth TSP, like the traditional TSP, is subject to RMDs once you reach the applicable age.
• No RMDs for Roth IRAs during your lifetime: Converted funds in a Roth IRA are exempt from RMDs, offering greater tax flexibility for estate planning and long-term use.
• Withdrawals only tax-free if “qualified”: You must hold the Roth IRA for at least five years and meet age or exception requirements for tax-free status.

All facts derive from IRS, OPM, and TSP guidance, and do not depend on product providers or financial institutions.

Do Roth Conversions Affect Social Security or Medicare?

Yes. Roth conversions increase your taxable income for the year, which may impact federal benefits:

• Social Security taxation: Higher taxable income from a Roth conversion could result in a larger portion of your Social Security benefits being taxed.
• Medicare premiums: increased income from conversions can raise your Medicare Part B and Part D premiums under Income-Related Monthly Adjustment Amounts (IRMAA) rules, as administered by the Centers for Medicare & Medicaid Services (CMS).

Both effects are based on the IRS’s calculation of “modified adjusted gross income” (MAGI). Federal retirees should review these potential consequences using official SSA and Medicare sources.

What Should Federal Retirees Consider Before Converting?

Before making any Roth conversion, consider these factors:

• Timing: If you expect a lower income year or tax rates are set to change, timing could affect total taxes owed.
• Eligibility: TSP rollovers to Roth IRAs are only permitted after separation from federal employment.
• Impact on federal benefits: Conversion income may affect Social Security taxes or Medicare premiums, as discussed above.
• Withdrawal rules: Know the five-year holding period requirement for tax-free Roth IRA withdrawals and how RMDs differ by account type.
• Risks: Converting in a high-income year or without considering all tax implications may lead to unexpected tax burdens. Rely on government-published rules when evaluating these risks.
