FERS Disability Retirement TSP Withdrawal Options

Your TSP After Separation

When you separate from federal service on FERS disability retirement, your Thrift Savings Plan (TSP) account remains yours. It continues to grow (or decline) based on your fund allocations, and you retain full control over interfund transfers and contribution fund elections — though you can no longer make new contributions since you are no longer receiving federal pay.

Your TSP balance is not part of your FERS disability annuity calculation. OPM computes your annuity based on your high-three average salary and years of service. The TSP is a separate asset you access on your own terms, subject to the withdrawal rules below.

The Rule of 55: Penalty-Free Access

The standard 10% early withdrawal penalty on tax-deferred retirement accounts applies to distributions taken before age 59½. But there is an exception that benefits many FERS disability retirees: the Rule of 55.

If you separate from federal service during or after the calendar year in which you turn 55, withdrawals from your TSP account are exempt from the 10% early withdrawal penalty. The key is the year of separation, not the year of withdrawal — once you separate in or after the year you turn 55, the exemption applies to all subsequent TSP withdrawals regardless of when you take them.

For disability retirees who separate before the year they turn 55, the 10% penalty applies to most TSP distributions. There is, however, a separate exception for distributions that are part of a series of substantially equal periodic payments (SEPP) over your life expectancy — but this method is rigid and carries penalties if you modify the payment schedule before age 59½ or five years, whichever is later.

There is also an IRS exception for distributions attributable to total and permanent disability. If you can demonstrate total disability under IRS standards (which are stricter than OPM's "useful and efficient service" test), the 10% penalty does not apply regardless of age. This requires IRS determination, not OPM approval.

Withdrawal Options

The TSP offers three withdrawal methods after separation:

Single withdrawal. You request a specific dollar amount as a one-time payment. You can make as many single withdrawals as you want, subject to the TSP's processing rules. Each withdrawal is taxed as ordinary income in the year you receive it.

Monthly payments. You set up a recurring monthly payment of either a fixed dollar amount or a calculated amount based on your life expectancy. Monthly payments provide a predictable income stream to supplement your FERS annuity and SSDI.

Annuity purchase. You use some or all of your TSP balance to purchase a life annuity from MetLife (the TSP's annuity provider). This converts your lump sum into guaranteed monthly payments for life. Once purchased, the annuity cannot be reversed or adjusted.

You can combine methods — for example, taking a partial single withdrawal to cover immediate expenses while setting up monthly payments from the remaining balance.

Tax Implications

Traditional TSP withdrawals are taxed as ordinary income at your marginal federal and state tax rates. This income adds to your adjusted gross income (AGI), which can affect Medicare Part B premium surcharges (IRMAA) if your modified AGI exceeds $109,000 (single) or $218,000 (married filing jointly) two years before the year in question.

Roth TSP withdrawals are tax-free if you meet the qualified distribution requirements: the Roth contributions have been in your account for at least five years, and you are age 59½ or older, disabled, or deceased. For disability retirees under 59½, the Roth contributions come out tax-free, but the earnings portion may be taxable.

One planning consideration: during the first year of FERS disability retirement, your annuity income is higher (60% of high-three) but your SSDI offset reduces the net FERS payment dollar-for-dollar. From month 13 onward, your FERS annuity drops to 40% of high-three. If you need to take TSP withdrawals, spacing them across lower-income years can reduce your overall tax burden.

Required Minimum Distributions

Under SECURE 2.0, required minimum distributions from your TSP account begin at age 73 if you were born between 1951 and 1958, or age 75 if you were born in 1959 or later. Roth TSP balances are exempt from RMDs during your lifetime as of the 2024 tax year.

For disability retirees who separate decades before RMD age, this is a long-term planning consideration. Your TSP has years or decades to compound before mandatory withdrawals begin, which can make Roth conversions during low-income disability years particularly tax-efficient.

The FERS Disability Retirement Guide covers TSP withdrawal timing alongside the SSDI offset calculation and 80% earnings limit, so you can model your complete post-retirement income.
