What Happens to Thrift Savings Plans When Separating from the Military

Hundreds of thousands of service members separate every year. In the chaos of terminal leave, TAP classes, and trying to actually figure out how you’ll make money to eat, one of your most critical post-military financial decisions can find itself  to the bottom of the pile: what to do with a Thrift Savings Plan (TSP) account. It’s an oversight that can either cost thousands or grow into a nice tidy sum, depending on the choice any veteran makes (or fails to make). Your TSP can quietly grow into a six-figure retirement asset or disappear in a wave of taxes and penalties within a year.

Understanding what happens to your TSP at separation and what options are available is one of the most important financial steps a transitioning service member can take.

The Thrift Savings Plan

Technically, the TSP is a defined-contribution retirement savings program for federal employees and members of the uniformed services, administered by the Federal Retirement Thrift Investment Board. It allows participants to invest pre-tax or after-tax (Roth) dollars across a menu of low-cost index funds. 

But more to the point, the Thrift Savings Plan is basically the military’s 401(k). And chances are good you started paying into it when you joined the military. A lot of people do because it’s just a good idea.

As of Dec. 31, 2024, the TSP held more than $963 billion in assets and served approximately 7.2 million participants, making it one of the largest defined-contribution retirement plans in the world.

For most of its history, enlisted service members and officers contributed to a TSP without any government matching. The plan existed alongside the traditional 20-year pension but offered no automatic employer contributions. 

That changed on Jan. 1, 2018, when the Blended Retirement System (BRS) was thrust upon the troops. Under BRS, all service members who entered the uniformed services on or after that date are automatically enrolled in the TSP at a contribution rate of 3% of basic pay. The Department of Defense contributes an automatic 1% of basic pay starting 60 days after entry into service and matches member contributions up to an additional 4%, for a total potential government contribution of 5% of basic pay. 

Those government contributions vest (meaning they belong to the service member) after two years of service.

Automatic TSP Changes

On the day a service member officially separates from the military, two things happen to their TSP automatically: contributions stop, and the account becomes a post-separation account. That’s where the automatic changes end.

The good news is that a separating member's account doesn’t close, isn't forfeited, and doesn't require any immediate action—as long as the balance remains at or above $200.  

The service member retains full control of the account, can continue to direct how the money is invested across the TSP's fund options, and can roll eligible money from other retirement accounts into the TSP. The only thing that stops is the payroll contribution.

If the balance falls below $200, however, the TSP account will close permanently. For veterans who plan to consolidate most of their TSP balance elsewhere but want to preserve the option to keep the account open, maintaining a buffer of several hundred dollars above the minimum is a must.

The 4 Post-Separation Options

Separated service members have four choices for what to do with their TSP. Each carries different tax implications, flexibility, and long-term consequences. Choose wisely. 

Option 1: Do Nothing.

In any situation, the simplest choice is always to do nothing. That doesn’t mean it’s the best choice. Or even a good one. In this case, leaving the money alone happens to be, for many veterans, the best option. 

Separating service members can leave their money in the TSP forever if they choose (again, provided the balance stays above $200). The account will continue to accrue investment earnings, and the veteran retains the ability to change allocations, request transfers, and take withdrawals under post-separation rules.

This is great for you because the TSP has exceptionally low expense ratios, along with administrative costs that are a fraction of what most retail mutual funds charge. For veterans who do not have a compelling reason to move the money elsewhere, remaining in the TSP maintains those cost advantages and keeps the retirement account intact.

Changes enacted by the SECURE 2.0 Act, increased the age at which TSP participants must begin taking required minimum distributions (RMDs) from 72 to 73, effective Jan. 1, 2023. That age will increase again to 75 on Jan. 1, 2033. 

For younger veterans, this means the TSP can sit untouched and growing for decades without mandatory withdrawal pressure.

Option 2: Roll the TSP Into an IRA or a New Employer's Plan

Service members who prefer to consolidate their retirement savings (or who want access to a broader range of investment options) can roll their TSP balance into an Individual Retirement Account (IRA) or a new employer's qualified retirement plan, like a 401(k), without incurring taxes or penalties, provided they follow IRS rollover rules.

A direct rollover—where funds are transferred directly from the TSP to the receiving account without passing through the veteran's hands—is the cleanest method. If the veteran instead receives a distribution check, the TSP is required to withhold 20% for federal income tax, and the veteran has 60 days to deposit the full pre-withholding amount into a qualifying account to avoid taxes and penalties on the withheld portion.

If that sounds complex and annoying, it is. If this is your chosen path, just roll your money over. It takes a few days, but in your new employer plan, you can continue contributing. Fund-type matching is essential. Traditional TSP balances must roll into a traditional IRA or pre-tax 401(k). Roth TSP balances roll into a Roth IRA. Mixing the two creates taxable events. 

Vets should consider rolling over a TSP into a more traditional account if they’re looking for more or better investment options or they want the simplicity of not managing multiple portfolios.

Option 3: Take Installment Payments

This one is for those closer to retirement. Separated participants can set up regular installment payments from their TSP, either a fixed dollar amount paid monthly, quarterly, or annually, or payments calculated based on life expectancy. 

This option will provide ongoing income without fully liquidating the account, and the remaining balance continues to earn investment returns between payments.

Younger veterans who are not yet 59½ should be advised that installment payments do not automatically exempt them from the 10% early withdrawal penalty unless they qualify for a specific IRS exception.

Option 4: Take the Money and Run

This is a tempting but terrible idea. TSP allows separated participants to request a partial distribution of a specified dollar amount or a total distribution of the entire account balance. In practice, this one is gonna cost you.

Any distribution from a traditional TSP is subject to federal income tax as ordinary income. If the veteran is under age 59½ at the time of the distribution, an additional 10% early withdrawal penalty typically applies, on top of the income tax owed.

 The combined tax and penalty burden on early cash-outs can range from zero to more than 40% of the withdrawn amount, depending on the veteran's income, filing status, and age.

For veterans carrying debt, the temptation to cash out a TSP to pay off credit cards or personal loans can be overwhelming. But this trade-off—eliminating consumer debt at the cost of long-term retirement savings and a substantial immediate tax hit—will do more financial harm than good over the course of your lifetime.

The idea of a $0 balance on that credit card bill is no doubt enticing. Resist the temptation. The math is straightforward: a 35-year-old veteran who withdraws $20,000 from a traditional TSP to pay off credit card debt may owe $4,000–$6,000 or more in combined taxes and penalties immediately, depending on their tax bracket. 

Meanwhile, the long-term compounding growth on that $20,000 is potentially $80,000 or more over 30 years at historical stock market return rates and would be permanently forfeited. Credit card debt can often be addressed through debt negotiation, income-driven repayment plans, or nonprofit credit counseling without triggering those massive retirement account losses.

Veterans in financial hardship should exhaust other options, including contacting a HUD-approved housing counselor, exploring VA financial assistance programs, or reaching out to a nonprofit like Veteran Debt Assistance, before drawing down their retirement savings.

Early Withdrawal Penalty Exceptions

There really is a waiver for everything, including the 10% early withdrawal penalty. The IRS provides several statutory exceptions, and two are particularly relevant to separating service members.

First, service members who separate from service during or after the calendar year in which they turn 55 (or age 50 for certain public safety employees) are exempt from the 10% penalty on distributions from that employer's plan. This is commonly called the "Rule of 55" and applies specifically to the TSP account associated with the employer from which the service member separated. It works for the TSP and 401(k) plans, but doesn’t apply to IRA distributions, which is one reason rolling a TSP into an IRA prematurely can close off an otherwise available penalty-free withdrawal window.

Second, qualified reservists called to active duty for more than 179 days may also qualify for a penalty exception on certain distributions, per the same IRS table. 

Income taxes still apply to any traditional TSP distribution, even when the penalty is waived. The penalty exception eliminates only the 10% surcharge, not the underlying income tax liability.

Roth vs. Traditional TSP

The tax treatment of a TSP withdrawal at separation depends heavily on whether contributions were made to a traditional or Roth TSP balance, or both.

Traditional TSP contributions are made pre-tax. Withdrawals are taxed as ordinary income. Roth TSP contributions are made with after-tax dollars. Qualified Roth TSP earnings (those withdrawn after the account is at least five years old and the participant is at least 59½, permanently disabled, or deceased) are distributed tax-free. Non-qualified Roth earnings are subject to income tax and may be subject to the early withdrawal penalty.

When to Make the Call

The period immediately surrounding military separation is the right time to take stock of a TSP account and make a deliberate plan. Before any final out-processing date, separating service members should confirm their TSP account login and contact information are current on tsp.gov, verify the account balance and fund allocations, designate or confirm a beneficiary on file, and determine whether a rollover, continuation, or distribution best fits their post-service financial plan.

Changes to contact information and beneficiary designations cannot be made through a former service's HR system after separation. They must be managed directly through the TSP's My Account portal. Failing to update this information can create complications in the event of an account owner's death or incapacity.

Separation from the military does not end a service member's relationship with the Thrift Savings Plan; it transforms it. Contributions stop, but the account lives on, the investments continue to grow, and the veteran retains full control. The most financially sound path is to leave the account in place or roll it into another qualified plan, preserving the tax-deferred growth that makes the TSP one of the most valuable benefits the military offers.
