Can You Leave Money in the TSP After Retirement? Minimum Balance, RMDs, and When It Makes Sense

Yes, You Can Leave It — And Often Should

After separating from federal service, you are not required to withdraw your TSP balance immediately. There is no deadline to remove your money, and no penalty for leaving it invested. Your account continues to grow tax-deferred (or tax-free for Roth balances) in the same TSP funds you selected during your career.

The only requirement is maintaining a minimum account balance of $200. If your balance drops below $200 — through withdrawals, fees, or market losses — the TSP will force-distribute the remaining balance to you via check.

Why the TSP Is Worth Keeping

The Thrift Savings Plan has structural advantages that most private-sector retirement accounts cannot match:

Ultra-low expense ratios. TSP investment funds charge approximately $0.42 per $1,000 invested annually (0.042% net expense ratio as of 2025). A comparable index fund at a major brokerage typically charges 0.03-0.10%, and actively managed funds charge 0.50-1.00%. Over a 20-year retirement, the difference between TSP fees and a typical IRA's fund fees on a $500,000 balance can exceed $15,000.

Institutional pricing on the G Fund. The TSP's G Fund earns a rate based on the weighted average yield of all outstanding U.S. Treasury securities with 4+ years to maturity — a rate not available to individual investors. There is no publicly available bond fund that replicates this combination of government guarantee, no principal risk, and long-term Treasury yields.

Simplicity. Five core index funds plus lifecycle L Funds. No sales loads, no surrender charges, no advisor fees. The interface is straightforward, and the investment menu is deliberately limited to prevent the "paradox of choice" paralysis that derails many retirees managing complex IRA portfolios.

When Keeping Money in the TSP Makes Sense

You do not need the income yet. If your FERS pension, Social Security, and other income cover your expenses, there is no reason to take distributions early. Let the balance compound.

You want fee protection. If a financial advisor is recommending you roll your TSP to an IRA they manage — especially on a 1% AUM fee basis — run the math. On a $500,000 balance, that is $5,000 per year in advisory fees versus roughly $210 per year in TSP expenses. The difference compounds.

You are not yet at RMD age. If you are under 73 (or 75, depending on your birth year), you have no obligation to take distributions. Leaving the money in the TSP gives you time to plan a tax-efficient drawdown strategy without being forced into distributions before you are ready.

Your Roth balance is growing. Roth TSP balances are exempt from lifetime RMDs under SECURE 2.0. Leaving Roth money in the TSP to grow tax-free indefinitely — and passing it to beneficiaries — can be one of the most valuable moves in your retirement plan.

When Moving Money Out Makes Sense

You want more investment options. The TSP offers five core index funds. An IRA at a major brokerage gives you access to thousands of funds, individual stocks, bonds, REITs, and other asset classes. If your retirement plan requires more diversification than the TSP offers, rolling to an IRA is reasonable.

You want consolidation. If you have retirement accounts scattered across multiple employers, rolling everything (including the TSP) into a single IRA simplifies management, beneficiary designations, and RMD calculations.

You need partial Roth conversion flexibility. While the TSP now offers in-plan Roth conversions (since January 2026), the conversion rules are more restrictive than IRA-based conversions. If your Roth conversion strategy requires granular control, an IRA may be more flexible.

The $200 Minimum Balance Rule

If your account balance drops below $200, the TSP will automatically close the account and mail you a check for the remaining amount. This is a force-out provision that applies to all separated participants.

If your balance is just above $200 and you are taking distributions, be aware of this threshold. A market decline or an installment payment could push your balance below $200, triggering an involuntary distribution.

Once the TSP closes your account, you cannot reopen it or roll money back into the TSP. If you want to maintain the option of keeping your TSP account active, ensure your balance stays well above the $200 floor.

RMDs Still Apply to Traditional Balances

Leaving money in the TSP does not exempt you from Required Minimum Distributions. Once you reach RMD age (73 if born 1951-1958, or 75 if born 1959 or later) and are separated from service, you must take annual distributions from your traditional balance.

The TSP automatically calculates your RMD based on your December 31 balance and your age. If you have not taken enough distributions during the year to satisfy the RMD, the TSP distributes the remaining amount by mid-December.

Roth TSP balances are completely exempt from lifetime RMDs — another reason to consider leaving Roth money in the account.
