🪜 Roth Conversion Ladder Basics
- A Roth conversion ladder moves money from a traditional IRA to a Roth IRA over several years, creating potential bridge income before age 59½.
- The converted amount becomes taxable income in the year of conversion, but the conversion itself does not trigger an early-withdrawal penalty.
- Taxes should be paid with money outside the converted balance.
⏱️ Contributions, Conversions, and the Five-Year Rule
- Roth IRA contributions can generally be withdrawn tax- and penalty-free at any time, although investment gains remain subject to separate rules.
- Each annual Roth conversion receives its own five-year waiting period, beginning January 1 of the conversion year.
🎖️ Military Planning Considerations
- The ladder discussed here operates within traditional and Roth IRAs, not directly inside the TSP.
- Starting conversions while still serving may mean recognizing additional income during peak earning years.
- Estimate the annual retirement-income gap first, then evaluate whether projected conversions, taxes, and timing realistically support it.
- Consult a qualified tax professional before executing the strategy.
🔀 Alternatives for Early-Retirement Income
- Rule 72(t)/SEPP: Provides early access but imposes a rigid withdrawal schedule.
- Rule of 55: May allow penalty-free TSP access when separation occurs during or after the year the participant turns 55.
- Taxable brokerage account: Offers flexibility over contribution amounts, withdrawals, and tax management without retirement-account age restrictions.
📊 Flexibility Can Be a Tax Advantage
Rob Moore’s illustrative retiring O-5 analysis found that a brokerage-based bridge produced roughly $13,000 less aggregate tax than the Roth conversion approach after accounting for the original traditional-account deduction. The broader lesson is to compare lifetime taxes, access rules, and optionality instead of assuming “taxable” automatically means tax-inefficient.
