Understanding Required Minimum Distributions (RMDs) in 2025: What Federal Employees Need to Know

 When planning for retirement, saving consistently is only half the equation. The other half? Knowing when and how you’re required to withdraw those savings. For federal employees with Traditional TSP accounts, IRAs, or other tax-deferred retirement funds, understanding Required Minimum Distributions (RMDs) is essential in 2025 and beyond.

Recent legislation has changed key rules that directly affect when withdrawals must begin, how they’re calculated, and what penalties may apply for mistakes. This guide breaks down what federal employees need to know about their first RMD, important updates for 2025, and strategies for minimizing the tax impact.

What Are RMDs and Why Do They Matter?

RMDs refer to the smallest withdrawals you must take annually from qualified retirement accounts after reaching a specific age, as mandated by law. These rules exist because the government wants to eventually tax the money that’s been growing tax-deferred in these accounts for decades.

RMDs apply to:

• Traditional Thrift Savings Plan (TSP) accounts

• Traditional IRAs

• 401(k), 403(b), and similar employer-sponsored plans

Notably, Roth IRAs and Roth TSP accounts contributed to after 2023 are exempt from RMDs during the account holder’s lifetime.

Key Changes for 2025 Under the SECURE 2.0 Act

Enacted in late 2022, the SECURE 2.0 Act introduced major updates to retirement withdrawal regulations. Here’s what federal employees should be aware of in 2025:

1. New Starting Age for RMDs

• If you were born between 1951 and 1959, your RMDs begin at age 73.

• Individuals born in 1960 or after are required to start taking RMDs at age 75.

This delay gives retirees additional years to grow their investments before being forced to draw from them—and it allows for tax planning in lower-income years.

2. Roth TSP Accounts Are No Longer Subject to RMDs

Beginning January 1, 2024, Roth balances in your TSP are exempt from RMDs. This allows you to prioritize tax-deferred accounts for withdrawals while preserving tax-free growth in Roth funds.

3. Lower Penalties for Mistakes

In the past, missing an RMD triggered a steep 50% penalty on the amount not withdrawn. As of 2025, this penalty has been reduced to 25%, and it can drop to just 10% if the mistake is corrected within two years.

When Is Your First RMD Required?

You must take your first RMD by April 1 of the year following the year you reach your RMD age. 

For example, 

• If you turn 73 in 2025, your first RMD is due by April 1, 2026.

• Every RMD after that must be taken by December 31 each year.

Heads-Up on Taxes: Delaying your first RMD until April 1 means you'll still need to take your second RMD by December 31 of the same year—potentially doubling your taxable income for that year and increasing your tax liability.

How to Calculate Your Required Minimum Distribution (RMD)

The IRS uses a life expectancy factor to determine how much you’re required to withdraw each year. The formula is straightforward:

RMD = Year-End Account Balance ÷ Life Expectancy Factor (from IRS Table)

Let’s say your Thrift Savings Plan (TSP) had $265,000 at the end of 2024, and your life expectancy factor at age 73 is 26.5. Your RMD for 2025 would be roughly:

$265,000 ÷ 26.5 = $10,000

While plan administrators like the TSP typically provide the required RMD amount, it’s still up to you to make sure the correct withdrawal is made on time to avoid penalties.

Which Accounts Are Affected?

Here’s a quick breakdown of common federal retirement accounts and their RMD status in 2025:

• Traditional TSP – RMDs required

• Roth TSP contributions made before 2024 – Subject to RMD requirements

• Roth TSP (after 2023) – No RMDs

• Traditional IRA – RMDs required

• Roth IRA – No RMDs during the account holder’s lifetime

Strategies to Manage Your RMDs Effectively

1. Roth Conversions

If you anticipate higher RMDs later in life, consider converting some Traditional TSP or IRA funds into Roth IRAs during lower-income years. This reduces future RMDs and spreads your tax liability over time.

2. Consolidate Accounts

Having several retirement accounts can make tracking RMDs more difficult. Streamline your finances by merging old 401(k)s or IRAs to reduce the chance of missing a required withdrawal.

3. Be Careful with Delaying

While delaying your first RMD until April 1 can buy you time, taking two withdrawals in one calendar year may increase your taxable income—and push you into a higher tax bracket.

4. Coordinate with Social Security and Pension

RMDs add taxable income. Timing withdrawals to avoid overlaps with Social Security or FERS pension benefits may reduce overall tax liability.

Mistakes to Avoid

• Failing to take your RMD on time – Missing the deadline, even by a day, could result in IRS penalties.

• Believing all Roth balances are RMD-free – Only Roth TSP contributions made after 2023 are exempt from RMDs.

• Not factoring in Medicare costs – Large RMD withdrawals can raise your income, which may increase your Medicare Part B premiums.

Conclusion

RMDs are more than a tax rule—they’re a powerful planning tool when handled correctly. For federal employees, smart RMD timing can protect retirement savings, reduce taxes, and create more financial flexibility.
