TSP Withdrawal Options at Military Separation: Everything You Need to Know

Your Thrift Savings Plan (TSP) account doesn't disappear when you separate from the military — but what you do with it in the months before and after separation can have significant financial consequences.

Here's what you need to know.

Your TSP Account After Separation

When you separate from the military, your TSP account remains intact. You do not have to do anything with it immediately. The account stays open, continues to be invested, and you can leave it there indefinitely.

What changes: you can no longer make contributions. Contributions come from military pay, and once you're out, there's no paycheck to contribute from. If you take a civilian job and your new employer offers a 401(k), that's a separate account — it does not merge with your TSP automatically.

Option 1: Leave It Alone

The simplest option is to leave your TSP where it is. The TSP is one of the lowest-cost retirement accounts in existence — its expense ratios are a fraction of what most commercial mutual funds charge (as low as 0.048% as of 2024, per tsp.gov).

If your balance is $200 or more, you can leave the account open indefinitely. You must begin Required Minimum Distributions (RMDs) at age 73 (per the SECURE 2.0 Act).

This is often the right answer if you're transitioning to a civilian job quickly and need time to evaluate your options clearly.

Option 2: Roll Over to an IRA

You can roll your TSP into a Traditional IRA (from Traditional TSP) or Roth IRA (from Roth TSP) without triggering taxes, as long as you do a direct rollover. A direct rollover means the money goes straight from the TSP to the new IRA — you never touch it.

Why roll over?

• More investment options (TSP has about 15 funds; an IRA can hold thousands)
• Potentially needed if you plan to do a Roth conversion strategy
• Consolidated with other retirement accounts for simpler management

Why not roll over?

• TSP expense ratios are lower than almost any IRA fund
• TSP has some creditor protections that IRAs may not
• Roth TSP cannot roll into a Traditional IRA without a tax event

Option 3: Roll Over to a New Employer's 401(k)

If your civilian employer offers a 401(k) that accepts incoming rollovers, you can transfer your TSP into it. This keeps everything in one place if you prefer consolidation.

Check your new plan's investment options and expense ratios before doing this — many 401(k) plans are significantly more expensive than the TSP.

Option 4: Withdrawal (Usually Not Recommended at Separation)

You can withdraw your TSP balance as cash. However, unless you are 59½ or older, this triggers:

• Income tax on the full amount at your marginal rate
• 10% early withdrawal penalty on top of that

On a $50,000 balance for someone in the 22% federal bracket: that's $11,000 in taxes plus $5,000 in penalties = $16,000 gone. You'd receive $34,000 of your $50,000.

The exception: Separation from service at age 55 or older — the 10% early withdrawal penalty does not apply if you separated from service in the year you turned 55 or later (for traditional employees; not FERS employees using the TSP). Verify this with a tax professional for your specific situation.

What About TSP Loans?

If you have an outstanding TSP loan when you separate, it becomes due. If you don't repay it within 90 days, it is treated as a taxable distribution — meaning you'll owe income tax on the unpaid balance, plus the 10% penalty if you're under 59½.

If you have a loan, repaying it before separation or ensuring you have a plan is critical.

The BRS Factor: What Happens to Government Matching

Under the Blended Retirement System (BRS, implemented starting January 2018), the government matches up to 4% of your base pay in TSP contributions after your first two years of service. These matching contributions vest immediately.

When you separate, you keep all government matching contributions that have vested. Unlike traditional pensions, BRS matching doesn't require you to serve 20 years — it's yours once contributed.

Tax Considerations

Traditional TSP contributions were pre-tax. Withdrawals in retirement will be taxed as ordinary income. If you're in a lower tax bracket in retirement than during service (common), this is generally favorable.

Roth TSP contributions were post-tax. Qualified distributions are tax-free. Combat zone contributions are also tax-free regardless of Roth vs. Traditional status.

Use MTT to Plan Your Post-Separation Budget

The months around separation involve simultaneously managing final pay, BAH end dates, and new civilian income. The Budget Planner in Military Transition Toolkit lets you map out your transition finances side by side so you don't get caught by a gap.
