A TSP beneficiary participant account is a Thrift Savings Plan account created for a surviving spouse who inherits a federal employee’s or service member’s TSP balance. It keeps the inherited money invested inside the TSP, using the same low-cost funds the deceased participant had access to, instead of forcing an immediate payout. Only a surviving spouse can have one, and the account carries its own rules on contributions, withdrawals, taxes, and required distributions.
Who Qualifies
Federal law restricts these accounts to one category of heir. Under 5 U.S.C. § 8433(e), a surviving spouse who was named as a full or partial beneficiary, or who inherits because no beneficiary designation was on file, can maintain the inherited portion inside the TSP.1Office of the Law Revision Counsel. 5 USC 8433 – Benefits and Election of Benefits Children, siblings, parents, trusts, and estates cannot. Those beneficiaries receive their share as a direct payment.
The account is also a one-generation vehicle. When the surviving spouse dies, whoever inherits what’s left cannot keep the money in the TSP. It must be paid out as a lump sum.1Office of the Law Revision Counsel. 5 USC 8433 – Benefits and Election of Benefits
How the Account Gets Opened
Someone has to notify the TSP that the participant has died. The main document is Form TSP-17, Information Regarding Deceased Participant, submitted with a certified copy of the death certificate. The form asks for the deceased participant’s full legal name, Social Security number or TSP account number, and the surviving spouse’s Social Security number and mailing address.2Thrift Savings Plan. TSP Bulletin 14-U-3 – Thrift Savings Plan Death Benefits
Processing generally takes 30 to 45 days after the TSP receives the form and death certificate. Each identified beneficiary then gets a Confirmation of Beneficiary Asset Transfer notice by mail.3Thrift Savings Plan. Reporting a Participant’s Death For a qualifying spouse, that notice includes what you need to access the new beneficiary participant account online.
How the Money Is Invested
When the account opens, your balance sits in whatever fund allocation your spouse had at death. If they held 60% in the C Fund and 40% in the G Fund, that’s where you start. Anything the deceased had in the mutual fund window is reinvested into TSP funds based on their investment election on file.4Thrift Savings Plan. A Guide for Beneficiary Participants
From there, you can redistribute among the standard TSP options: the G, F, C, S, and I Funds, and the Lifecycle (L) Funds that adjust their stock-and-bond mix over time.5Thrift Savings Plan. TSP Investment Options The interfund transfer tools work the same way they do for any TSP participant.
What You Cannot Do With the Account
The account has three hard limits set by statute. You cannot make new contributions, you cannot move outside retirement money into the account, and you cannot borrow against the balance.1Office of the Law Revision Counsel. 5 USC 8433 – Benefits and Election of Benefits The “no new money in” rule covers rollovers from private-sector 401(k)s, IRAs, and even your own personal TSP account.4Thrift Savings Plan. A Guide for Beneficiary Participants Money flows only one direction: out.
Withdrawal Options
You have more flexibility taking money out than many people expect. The choices are:
- Partial withdrawals of at least $1,000 (the minimum does not apply if you’re withdrawing the entire balance, your full traditional balance, or your full Roth balance).
- Installment payments on a monthly, quarterly, or annual schedule. If you set a fixed dollar amount, the minimum per installment is $25.
- A full withdrawal of the entire balance in a single payment.
These options come from the TSP’s current guide for beneficiary participants.4Thrift Savings Plan. A Guide for Beneficiary Participants
No 10% Early Withdrawal Penalty
This is the most valuable feature of a beneficiary participant account and the one people most often overlook. Distributions are not subject to the 10% early withdrawal penalty, whatever your age.4Thrift Savings Plan. A Guide for Beneficiary Participants A 45-year-old surviving spouse can take money out without the penalty that would normally apply to a regular TSP withdrawal before age 59½.
The protection disappears the moment you combine the account with your own. If you roll the beneficiary participant account into your civilian or uniformed services TSP, every dollar in the resulting account, including the inherited portion, follows the standard early withdrawal rules. If you’re under 59½ and might need the money, keeping the accounts separate usually makes sense.
How Distributions Are Taxed
Withdrawals from the traditional balance count as ordinary income for federal tax purposes. Roth contributions come out tax-free. Roth earnings can also come out tax-free if the distribution is qualified, which generally requires that five years have passed since January 1 of the year your spouse first made a Roth TSP contribution.4Thrift Savings Plan. A Guide for Beneficiary Participants
For lump-sum or partial withdrawals eligible for rollover, the TSP withholds 20% for federal income tax before sending you the balance. It does not withhold for state or local tax, so if your state taxes retirement income, plan for that at filing time.
Required Minimum Distributions
Beneficiary participant accounts are subject to the required minimum distribution rules under Internal Revenue Code Section 401(a)(9).6eCFR. 26 CFR 1.401(a)(9)-1 – Minimum Distribution Requirement in General As a surviving spouse, you are exempt from the 10-year payout rule that applies to most other inherited retirement accounts. You take annual RMDs based on your own life expectancy using the IRS Single Life Expectancy Table.7Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs
The math is simple: divide the December 31 prior-year balance by the applicable factor from the IRS table. The general age at which RMDs must begin is 73.7Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs Timing rules for inherited accounts can shift depending on the deceased participant’s age at death, so check your specific situation.
Missing an RMD is expensive. The IRS imposes a 25% excise tax on the amount you should have taken. Correct the mistake within two years and the penalty drops to 10%.7Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs The TSP calculates the required amount for you, but you’re responsible for taking it on time.
Rolling Into Your Own TSP or an IRA
If you’re a federal employee or service member with your own TSP account, you can merge a beneficiary participant account into it through an inter-plan rollover. You can also consolidate multiple beneficiary participant accounts into a single personal TSP account. What you cannot do is the reverse: move your personal TSP into the beneficiary participant account, or combine two beneficiary participant accounts with each other.4Thrift Savings Plan. A Guide for Beneficiary Participants
One technical point: if your spouse had tax-exempt contributions in their traditional balance, typically from combat zone pay, that portion cannot transfer into your personal TSP through the inter-plan rollover. It gets paid to you directly.4Thrift Savings Plan. A Guide for Beneficiary Participants
You can also roll distributions to a traditional IRA or an eligible employer plan to keep deferring taxes. A conversion into a Roth IRA is possible too, though you’ll owe income tax on the full converted amount in that year. One limitation to keep in mind for your own beneficiaries: death benefit payments made from the account after you die cannot be rolled over.4Thrift Savings Plan. A Guide for Beneficiary Participants
When Merging Accounts Can Hurt You
The Roth qualification rules differ between the two account types. In a beneficiary participant account, Roth earnings are tax-free once five years have passed since your spouse’s first Roth contribution. In your own TSP account, qualified Roth earnings require both the five-year period and reaching age 59½, becoming permanently disabled, or dying.4Thrift Savings Plan. A Guide for Beneficiary Participants Rolling over before you turn 59½ could mean paying tax on Roth earnings that would otherwise have been tax-free.
The early withdrawal penalty is the other trap. Once accounts are merged, every dollar becomes subject to the standard rules, including the inherited portion that had been penalty-free.
Naming Your Own Beneficiary
Once the account is open, decide who receives what’s left when you die. File Form TSP-3, Designation of Beneficiary, specifically for the beneficiary participant account. If you also have your own civilian or uniformed services TSP account, you need a separate Form TSP-3 for each one.8Thrift Savings Plan. TSP-3 Designation of Beneficiary
Without a valid Form TSP-3 on file, the TSP pays out under a statutory order of precedence:
- First, your surviving spouse.
- Second, your children in equal shares, with a deceased child’s share divided among that child’s descendants.
- Third, your parents, equally or to the surviving parent.
- Fourth, the executor or administrator of your estate.
- Fifth, your next of kin under the laws of the state where you lived.
Whoever inherits the remaining balance receives it as a lump-sum payment. The funds cannot stay in the TSP.1Office of the Law Revision Counsel. 5 USC 8433 – Benefits and Election of Benefits Filing Form TSP-3 lets you decide who gets the money and in what proportion, rather than defaulting to the hierarchy above.
