TSP Rollover Decisions for Military Pilots Transitioning to the Airlines
The Thrift Savings Plan is one of the lowest-cost retirement savings platforms available to military pilots. It is also one of the first accounts they roll out of at separation — frequently without analysis, and sometimes at significant long-term cost. This article frames the four TSP decisions military pilots face at transition and identifies the variables that determine the right answer for each.
TSP rollover decisions are not time-sensitive in the sense that they force an immediate choice — TSP assets can remain in the plan indefinitely after separation. They are time-sensitive in the sense that the tax year of separation and the year of initial airline income create a specific window where conversion and rollover strategies are cheapest. That window closes. The decision to do nothing is itself a decision.
The Four TSP Decisions at Separation
Every separating military pilot faces the same four choices for existing TSP assets. These are not mutually exclusive — partial actions are available — but each has distinct tax, cost, and flexibility implications.
Decision 1: Leave TSP Assets in the TSP
TSP assets can remain in the Thrift Savings Plan after separation. The account remains active, funds are available, and expenses remain among the lowest in the industry (approximately 0.042% as of 2024). Separated members cannot make new contributions, but existing assets grow and can be invested across TSP's core fund lineup (G, F, C, S, I, and L funds) (Federal Retirement Thrift Investment Board [FRTIB], 2024).
Leaving assets in TSP may make sense when: the TSP's fund options meet the investor's needs, no Roth conversion strategy is planned, and the investor values the TSP's institutional credibility and cost structure over broader investment flexibility.
Decision 2: Roll to a Traditional IRA
Traditional TSP assets can be rolled to a traditional IRA on a tax-free basis. This expands investment options significantly — from TSP's five core funds to the full universe of available securities — and consolidates military retirement assets into a single account structure that may be easier to manage alongside airline 401(k) contributions (Internal Revenue Service [IRS], 2024, Publication 590-A).
Common trade offs of rolling to an IRA are: loss of TSP's extremely low expense ratios, potential advisory fees on IRA assets if held in a managed account, and the loss of TSP's unique features (notably, the G Fund's government-rate return with no duration risk, and the TSP annuity option).
Decision 3: Roll to the Airline 401(k)
Most major airline 401(k) plans accept incoming rollovers from qualified plans, including TSP. Rolling TSP assets into the airline plan consolidates retirement accounts and allows the combined balance to be managed within a single employer-sponsored structure (IRS, 2024, Publication 575).
This option requires confirming the airline's plan document accepts rollovers, understanding the airline plan's investment options and expense ratios, and evaluating whether the airline plan's institutional funds are comparable to or better than TSP options. For carriers using low-cost index fund lineups, the fund quality difference between TSP and the airline 401(k) is small. For carriers with higher-cost fund lineups, the difference is the difference can become meaningful over long time horizons.
Decision 4: Roth Conversion
Traditional TSP assets (pre-tax contributions and growth) can be converted to a Roth IRA. The converted amount is treated as ordinary income in the year of conversion and taxed accordingly. Future growth on converted assets is permanently tax-free under current law (IRS, 2024, Publication 590-A).
The conversion opportunity created by the military-to-airline transition is specific and time-limited. If the separation year and the first partial year of airline income create a year with below-average taxable income, Roth conversion may be executable at lower marginal rates than will be available after airline seniority builds. A pilot who separates in October and starts airline training in January has roughly one calendar year of compressed income. That window is the Roth conversion calculation period.
The Variable That Changes the Analysis: Airline Income Timing
TSP rollover decisions made without modeling airline income are incomplete. The addition of airline W-2 income — even at first-year first officer rates — changes marginal tax bracket calculations for the transition year and the years immediately following.
Specific variables to model before making TSP decisions:
Where TSP Is Structurally Difficult to Replace
The G Fund. TSP's Government Securities Investment Fund earns interest at long-term Treasury rates while maintaining no duration risk and no principal loss. No equivalent exists in the IRA or 401(k) universe. If a pilot's plan calls for a significant bond or stable-value allocation, the G Fund may be the best available instrument.
Expense ratios. TSP's core funds carry expense ratios of approximately 0.042%. Most IRA and 401(k) alternatives carry higher costs. The compounding difference over 20–30 years is measurable.
TSP annuity option. Separated members can purchase a TSP annuity from the TSP's insurance partner. This option is eliminated if assets are rolled out. For beneficiary planning purposes, the TSP annuity with survivor options may have value that commercial annuities do not replicate at equivalent cost.
Where Deeper Analysis Is Required
Roth conversion opportunity. If TSP balances are large and the transition year creates a low-income window, partial Roth conversions executed correctly can permanently reduce the tax liability on decades of compounded growth. This requires individual modeling — not a general rule.
Required Minimum Distributions (RMDs). TSP is subject to RMD rules beginning at age 73 (SECURE 2.0 Act of 2022, Pub. L. No. 117-328). A Roth IRA is not subject to RMDs during the owner's lifetime. If reducing forced distributions in retirement is a planning goal, this changes the conversion analysis.
Beneficiary flexibility. TSP beneficiary options are more limited than IRA beneficiary options. For pilots with complex estate planning needs — trusts, multiple beneficiaries, or minor children — IRA structure provides more flexibility.
What Not to Do
The most common TSP errors in this transition are not strategic — they are administrative.
Do not cash out TSP assets. A full distribution of TSP assets triggers ordinary income tax on the entire balance plus a 10% early withdrawal penalty if the service member is under age 59½ (IRS, 2024, Publication 575). The penalty exception for separation from service after age 55 applies to employer plans — but only in the year of separation and after, and the rules are specific. Confirm eligibility before treating a separation distribution as penalty-free.
Do not rollover Roth TSP to a traditional IRA. Roth TSP contributions must be rolled to a Roth IRA or a Roth 401(k). Rolling Roth TSP to a traditional IRA is an error that has tax consequences and may require correction (IRS, 2024, Notice 2014-54).
Do not use the 60-day indirect rollover method when a direct rollover is available. The 60-day indirect rollover rule requires completing the transfer within 60 days of receipt. Missing the deadline triggers full income tax on the distribution. A direct trustee-to-trustee transfer eliminates this risk (IRS, 2024, Publication 590-A).
Frequently Asked Questions
Can I keep contributing to TSP after I separate?
No. Separated service members cannot make new TSP contributions. Existing balances remain in the account and continue to grow, but no new deposits can be made. If you are under BRS, your agency automatic and matching contributions also stop at separation. The only caveat to this is if you remain serving in the reserve component.
What happens to TSP if I die before rolling it over?
TSP assets pass to named beneficiaries. If no beneficiary is designated, TSP follows a statutory order of precedence that may not reflect your intent. Reviewing and updating TSP beneficiary designations at separation is a basic but frequently skipped administrative step.
Can I roll my airline 401(k) into TSP later?
No. TSP does not accept incoming rollovers from civilian 401(k) accounts for separated service members. This is generally a one-way door — once assets are out of TSP, they cannot be returned. Active duty service members with concurrent civilian employment can roll certain assets in; separated service members cannot.
What is the tax treatment of TSP distributions in retirement?
Traditional TSP distributions are taxed as ordinary income in the year received. TSP does not have special capital gains treatment. For pilots with both TSP and Roth IRA assets in retirement, sequencing distributions between taxable and tax-free accounts becomes a central tax planning question — particularly in the years before Social Security begins and before Required Minimum Distributions are required.

Specific variables to model before making TSP decisions:
- What is the expected taxable income in the year of separation, including terminal leave pay, any lump-sum leave payout, and partial-year airline income?
- What is the expected taxable income in years two through five as airline seniority builds and pay increases?
- Is there Roth TSP balance that can be rolled to a Roth IRA without tax? (Roth TSP to Roth IRA rollovers are not taxable.)
- Does the airline 401(k) accept incoming Roth rollovers? (Not all plans do.)
- Is there any plan to use TSP's annuity option? If so, rolling assets out forfeits that option.
Where TSP Is Structurally Difficult to Replace
