1. What changes when you leave

Your uniformed services TSP account doesn’t close when you retire or separate. It stays invested in the funds you chose. What changes:

2. Your three choices

3. Combat-zone money

Pay earned in a combat zone was tax-free, and so were the TSP contributions made from it. Your TSP statement shows this as your tax-exempt balance. It follows its own rules:

Worth asking about

TSP rules let tax-exempt money go to a Roth IRA if the IRA accepts it. Since that money was never taxed, moving it to a Roth adds no tax on those dollars, and future growth can be tax-free. Get the exact tax treatment confirmed by a tax professional before you move it.

4. The 10% penalty

Withdrawals from a traditional balance before age 59½ usually owe a 10% penalty on the taxable part, on top of income tax. The penalty doesn’t apply if:

5. Your spouse’s rights

If you’re married, your spouse must sign off before you withdraw. Your spouse is also entitled to a joint annuity with a 50% survivor benefit unless they waive it. These rules apply even if you’re separated. Name your beneficiaries too: see TSP death benefits.

7. Frequently asked questions

Can I leave my TSP after I leave the military?

Yes. Your uniformed services account stays open and invested after you separate or retire. Service contributions stop, but you can leave the money there and withdraw it later.

Can I move my military TSP into my civilian TSP account?

Yes, after you separate from the uniformed services, if you have a civilian TSP account. The exception is tax-exempt combat-zone money in your traditional balance, which can’t go into a civilian account and stays in the uniformed services account.

Is combat-zone TSP money taxed when I withdraw it?

The tax-exempt contributions are not taxed, but their earnings are, if they are in your traditional balance. Tax-exempt money in your Roth balance is never taxed. Withdrawals include a proportional share of tax-exempt money.

Do military retirees pay the 10% penalty on TSP withdrawals?

Usually, if they are under 59½. The penalty is waived if you separate in or after the year you turn 55, but most military retirees leave younger. Installments based on life expectancy are also exempt.

Does my spouse have to agree to my TSP withdrawal?

Yes. If you are a married uniformed services participant, your spouse must consent to a withdrawal, and is entitled to a joint annuity unless they waive it.
