TSP withdrawal strategy has gotten complicated with all the Rule of 55 exceptions, Required Minimum Distribution timelines, and Roth conversion windows flying around. As someone who assumed the TSP withdrawal rules were the same as a civilian 401(k) until I actually had to use them, I learned exactly how military retirement changes the distribution math. Today I will share it all with you.
Why TSP Withdrawal Strategy Matters
The accumulation phase of TSP — contributing money for 20-30 years — gets most of the attention. The distribution phase, when you actually start withdrawing money in retirement, has rules and options that can significantly affect how much the IRS takes and how long the money lasts. Military retirees who receive a pension have an income floor that changes the TSP withdrawal calculus compared to civilians who depend entirely on their savings.
The Penalty Exception Most Military Retirees Don’t Know
Normally, withdrawing from a traditional TSP before age 59½ triggers a 10% early withdrawal penalty in addition to income taxes. The Rule of 55 exception allows penalty-free withdrawals from a TSP or workplace plan if you separate from service in or after the year you turn 55. For military retirees who retired at 38 or 42, this may allow penalty-free TSP withdrawals immediately after retirement — 17-21 years before the standard 59½ threshold.
That’s what makes this exception endearing to military retirees who retire young — it means the TSP is accessible for supplemental income from day one of retirement without penalty, provided they separated in or after the year they turned 55.
Required Minimum Distributions
Traditional TSP withdrawals become mandatory at age 73 under current law. The RMD is calculated by dividing the account balance by a life expectancy factor from IRS tables. Miss your RMD and the penalty is 25% of the amount that should have been withdrawn. TSP will calculate your RMD for you and prompt you — but only if you’re paying attention when those notices arrive.
Roth TSP contributions do not have RMDs during the owner’s lifetime under current law. This is one argument for Roth TSP contributions during your career: avoiding forced distributions in your 70s that could push you into a higher bracket.
The Roth Conversion Strategy
Military retirees with pension income but modest TSP have a potential opportunity in early retirement: converting some traditional TSP to Roth each year, up to the top of your current bracket, can reduce future RMDs and the associated taxes. I’m apparently someone who assumed this was always a good idea until an advisor pointed out that pension income alone can put you in a bracket where conversion math barely pencils. Run the actual numbers with a tax professional before committing.
The Withdrawal Order Question
Probably should have led with this framework: for military retirees with multiple accounts (TSP, Roth IRA, taxable brokerage), the conventional sequence is to draw down taxable accounts first, then traditional tax-deferred accounts, then Roth accounts last. The reasoning: Roth accounts have no RMDs and tax-free growth, so letting them compound longest maximizes their value. Work through this with a fee-only advisor who understands military retirement before your first year of distributions.
