Military members who’ve served honorably have access to the Thrift Savings Plan (TSP), a powerful retirement savings vehicle that rivals many private sector 401(k) plans. When you separate or retire from military service, understanding your TSP rollover options is crucial for maximizing your retirement income and maintaining tax-advantaged growth. This guide breaks down your choices, timelines, and strategic considerations.
The TSP is a defined-contribution retirement plan exclusively available to federal employees and uniformed service members. Military participants benefit from automatic agency contributions (1% of basic pay) plus matching contributions up to 5%, making the TSP one of the most generous employer-sponsored plans available.
Your TSP account grows tax-deferred across a range of investment funds, from conservative Government Securities Investment Fund (G Fund) options to diversified index funds. The plan’s low expense ratios—among the lowest in the industry—mean more of your money works for you rather than paying fees.
However, upon separation or retirement, you must decide what to do with your accumulated TSP balance. You can’t simply leave it indefinitely without making an intentional choice, and your options carry different tax implications and flexibility levels.
Your Four Primary TSP Rollover Options
Option 1: Leave Your Money in TSP
Many military retirees leave their TSP funds in the plan after separation. You’ll maintain access to the TSP’s low fees and investment flexibility while postponing Required Minimum Distributions (RMDs) until age 73 if you don’t own 5% or more of the business (military retirees typically don’t). This option provides stability and simplicity if you’re satisfied with TSP’s investment options and administrative structure.
The catch? You’ll face restrictions on new contributions after separation, and accessing your money before 59½ outside of specific exceptions triggers a 10% early withdrawal penalty plus income taxes.
Option 2: Roll Over to a Traditional IRA
Rolling your TSP balance into a Traditional IRA offers greater investment flexibility and potentially lower fees, depending on your IRA provider. A Traditional IRA rollover preserves the tax-deferred status of your savings and allows you to invest in stocks, bonds, mutual funds, and alternative investments unavailable through TSP.
This option is particularly appealing if you want to consolidate multiple retirement accounts or if you anticipate needing investment options TSP doesn’t provide. Keep in mind that IRAs have their own RMD rules starting at age 73, and you’ll need to carefully manage any existing Traditional IRA balances if you later want to execute a backdoor Roth conversion.
Option 3: Roll Over to a Roth IRA
Converting your TSP balance to a Roth IRA through a direct rollover triggers immediate federal income tax on the entire amount. However, subsequent growth and qualified distributions are tax-free, and Roth IRAs have no RMDs during your lifetime, offering superior estate planning flexibility.
This option makes sense if you’re in a lower tax bracket at separation (perhaps taking a break before civilian employment) or if you expect significantly higher tax brackets in retirement. Use our Retirement Income Calculator to model different income scenarios before committing to a conversion.
Option 4: Roll Over to Your New Employer’s 401(k)
If you’re transitioning to civilian employment with a company offering a 401(k), you might roll your TSP balance directly into that plan. This consolidates your retirement savings and may provide loan options that IRAs don’t offer.
However, examine the new plan’s fee structure, investment options, and loan terms carefully. Not all 401(k) plans are created equal, and TSP’s low-cost structure is difficult to match in the private sector.
Key Considerations When Choosing Your Rollover Strategy
Tax Consequences and Your Current Situation
Your immediate tax situation significantly impacts rollover decisions. Military members separating with severance packages or taking terminal leave may have lower income years that make Roth conversions attractive. Conversely, if you’re already earning substantial civilian income, staying in Traditional TSP or rolling to a Traditional IRA preserves tax-deferral without triggering a large tax bill.
Your Age and Early Withdrawal Needs
Military retirees under 59½ face a different calculus than those over 59½. TSP offers the 72(t) substantially equal periodic payment exception, allowing penalty-free withdrawals before 59½ if you set up qualifying distributions. This is often unavailable with IRAs in the same way.
If you anticipate needing funds before 59½, model this carefully using our Early Withdrawal Penalty Calculator to understand the true cost of accessing your money early.
Investment Preferences and Fee Structure
TSP’s expense ratios are exceptionally low—often 0.025% to 0.05%. Most IRAs and 401(k) plans charge more, though some robo-advisors and low-cost brokers compete favorably. Unless you need investments TSP doesn’t offer, the fee advantage alone might justify staying put.
Survivor and Estate Planning Considerations
Military-specific survivor benefit considerations may apply to your TSP balance. Roth IRAs offer superior tax-free growth for heirs, while Traditional accounts trigger income tax for beneficiaries. Discuss these implications with an estate planning attorney.

Frequently Asked Questions About Military TSP Rollovers
Q: Can I roll my TSP to a military-specific retirement plan?
A: You cannot roll TSP directly into another military benefit system. However, you can roll it to a Traditional IRA, Roth IRA, or civilian 401(k). Some military-focused financial advisors specialize in helping you coordinate TSP rollovers with military-specific tax strategies and survivor benefits.
Q: What’s the deadline to roll over my TSP after separating?
A: There’s no strict deadline to roll over TSP funds, but you should act deliberately rather than allowing money to sit without purpose. If you separate but don’t immediately address your TSP, you’ll continue receiving statements and must manage the account. RMDs begin at age 73 regardless of when you actually roll it over, so plan ahead.
Q: Will my military pension affect my TSP rollover decision?
A: Your military pension provides guaranteed income, which significantly impacts rollover strategy. Since your pension covers baseline expenses, your TSP can be invested more aggressively for growth, or more conservatively since growth is a secondary goal. Model your complete retirement income picture including both pension and TSP.
Q: Can I do a Roth conversion of my entire TSP balance and spread the tax bill over multiple years?
A: No—when you convert TSP to a Roth IRA, the entire taxable amount is includable in your income in the year of conversion. You cannot split the conversion across multiple tax years. However, you could do a partial conversion one year and another partial conversion in a subsequent year if you’re concerned about tax bracket creep.
Q: Are there special TSP withdrawal rules for military-connected disability or medical hardship?
A: TSP offers loans and in-service withdrawals for specific hardships, though these are separate from rollover decisions. If you have service-connected disability, explore VA benefits and other programs before tapping retirement savings. The combination of military pension, TSP, and VA disability compensation often provides more tax-efficient income than liquidating TSP early.
