A beneficiary participant account can remain in TSP
A surviving spouse can generally maintain inherited TSP assets in a beneficiary participant account, subject to TSP rules. Keeping the account can preserve TSP administration and investment choices while the spouse reviews distributions, access, beneficiaries and future transfer options.
A direct transfer must use an eligible receiving arrangement
When a transfer is permitted, the account title and receiving institution matter. A direct transfer can avoid the risks created when a check is first paid to the spouse. Traditional and Roth balances require separate review, and a required distribution cannot be transferred.
Keeping beneficiary status and using an own IRA are different decisions
For inherited IRA assets, a surviving spouse can have the choice to remain a beneficiary or treat eligible assets as the spouse's own. Timing affects required distributions and access rules. TSP beneficiary participant accounts follow their own plan process, so do not assume an IRA election automatically applies inside TSP.
Payments, liquidity and beneficiaries belong in the same comparison
Before transferring, compare installment and withdrawal access, investment choices, administrative costs, beneficiary rules and the spouse's cash reserve. A transfer into an insurance contract can add surrender terms and contract limits that did not exist in TSP.
Guaranteed income should be compared after the TSP route is understood
A spouse may later compare the TSP life annuity, eligible IRA transfer choices and an external annuity when appropriate. These are distinct routes. Payment options, liquidity, inflation exposure, beneficiary value and issuer strength can differ, and an external contract is not a TSP guarantee.

Frequently asked questions
Can a surviving spouse keep inherited money in TSP?
A surviving spouse can generally receive a beneficiary participant account and keep eligible inherited assets in TSP, subject to current plan rules.
Can a TSP beneficiary participant account transfer to an IRA?
Eligible amounts may be transferable to an eligible IRA when the transfer is arranged correctly. Required distributions and account registration must be reviewed first.
Should a spouse use an inherited IRA or an own IRA?
That decision can affect access and required distributions. A spouse should compare age, timing, beneficiary goals and tax advice before making the election.
Is the TSP life annuity the same as an IRA annuity?
No. The TSP life annuity is a TSP withdrawal option. An IRA annuity is a separate insurance contract with its own issuer, costs, liquidity and income terms.
Does an annuity remove inherited-account RMDs?
No. An annuity does not override required-distribution rules. The contract and payout design must be compatible with applicable deadlines.
