Understanding TSP Disbursement
Exploring Your TSP Disbursement Options

-
Partial Distributions
You can withdraw a minimum of $1,000 while keeping the rest invested. This option is useful for one-time expenses like home renovations or medical bills. Traditional withdrawals are taxed as income, while qualified Roth withdrawals are tax-free.
-
Total Distribution
A total distribution closes your TSP account and provides immediate access to your entire balance. This is often chosen by those rolling funds into an IRA or private-sector 401(k) for broader investment options. However, withdrawing a large sum could push you into a higher tax bracket. For example, a $500,000 lump withdrawal could result in significant federal and state taxes, making it wise to consult a tax professional beforehand.
-
Annuity Purchase
With at least $3,500, you can purchase an annuity for guaranteed income. Annuities are irreversible and may offer lower returns than staying invested in the TSP. For example, a $200,000 annuity might provide $1,200 monthly.
-
Installment Payments
Installments let you schedule regular payments (monthly, quarterly, or annually) based on a fixed amount or life expectancy. This method provides steady income while keeping your remaining balance invested. For example, a 70-year-old retiree might opt for $2,000 monthly installments calculated using the IRS Uniform Lifetime Table, adjusting withdrawals annually to reflect account performance and longevity.
How to Request a Disbursement: Process and Timing
-
Partial or total distributions: Specify the amount and destination (direct deposit or check). Partial withdrawals require a minimum of $1,000, and you can make multiple requests over time.
-
Annuities: Submit a request, and the TSP will transfer funds to your chosen insurance provider. Compare vendor rates using tools like the TSP Annuity Calculator.
-
Installments: Use the Model Installments tool to simulate payments. For example, a $500,000 balance might generate $2,500 monthly over 20 years, depending on investment returns.
Tax Implications, Penalties, and 2025 Rule Changes

Taxes and penalties significantly impact your disbursement strategy. Here’s what to know: Traditional vs. Roth TSP Traditional: Withdrawals are taxed as income. If you’re under 59½, a 10% early withdrawal penalty applies unless you qualify for exceptions (e.g., disability, unreimbursed medical expenses). Roth: Contributions are tax-free upon withdrawal if you’re over 59½ and meet the 5-year holding period. Starting in 2024, Roth balances are exempt from Required Minimum Distributions (RMDs), offering long-term tax advantages. Required Minimum Distributions (RMDs) In 2025, RMDs begin at age 73 (up from 72). If you turn 73 that year, your first RMD is due by April 1, 2026, with subsequent withdrawals by December 31 each year. The penalty for missed RMDs drops to 25% (or 10% if corrected within two years). For example, a retiree with a $1M traditional TSP balance at age 73 would need to withdraw roughly $36,500 annually (based on a 27.4-year life expectancy divisor).
Tax-Smart Strategies
Roth conversions: Convert traditional funds to Roth gradually to reduce future RMDs and taxable income.
Bracket management: Withdraw traditional TSP funds in lower-income years (e.g., early retirement) to stay in a lower tax bracket.
1. Ignoring Tax Withholding: The TSP defaults to 20% federal withholding on traditional withdrawals. If you need more withheld to avoid a tax bill, submit IRS Form W-4R.
2. Overlooking State Taxes: Seven states (e.g., Florida, Texas) have no income tax, but others tax TSP withdrawals. Check your state’s rules.
3. Misjudging Annuity Costs: Annuity fees and inflation risk can erode returns. Compare quotes and consider keeping a portion invested.
