Federal retirement
What to do with your TSP when you retire
Should I keep my TSP or roll it over when I retire?
There is no universal answer. The TSP offers among the lowest expense ratios available and strong creditor protection, while an IRA offers far more investment choice and withdrawal flexibility. Some federal retirees split the difference: keep a portion in the TSP for its cost advantage and move a portion to an IRA for flexibility.
The short version
- The Thrift Savings Plan's administrative expenses are among the lowest of any defined contribution plan in the United States.
- TSP assets receive federal creditor protection under ERISA-equivalent rules; IRA creditor protection is set by state law and varies.
- Federal retirees are not required to move their TSP at separation, and there is no deadline forcing the decision.
- The TSP permits partial withdrawals and installment payments, but its withdrawal options remain less flexible than an IRA's.
What the TSP does better than an IRA
Cost is the headline. The TSP's expense ratios are a fraction of what most retail funds charge, and that gap compounds across a retirement that may run thirty years. On a large balance, the difference is not trivial.
Creditor protection is the quieter advantage. Money in the TSP is shielded from creditors under federal rules. In an IRA, that protection depends on your state, and several states offer considerably less.
There is also the G Fund, which has no direct equivalent outside the TSP. It offers the yield characteristics of longer-dated government securities without the price volatility, which is a genuinely unusual combination.
What an IRA does better than the TSP
Choice, mainly. The TSP offers five core funds and a set of lifecycle funds built from them. That simplicity is a feature for many people, but it makes certain strategies impossible. You cannot hold individual securities, and you cannot implement an allocation the menu does not support.
Withdrawal flexibility matters more than people expect. The TSP has improved considerably, but an IRA still permits more granular control over which assets you sell and when, which matters for tax management.
An IRA also makes Roth conversions easier to execute and to sequence, and it consolidates accounts so one plan governs everything rather than two.
Why splitting is often the practical answer
Keeping some balance in the TSP preserves access to the G Fund and the low cost structure. Moving the remainder to an IRA buys the flexibility to manage withdrawals, run conversions, and implement an allocation the TSP menu cannot express.
The right split depends on what each portion is doing. Money you will draw in the next several years benefits from flexibility. Money that functions as your stable, low-volatility ballast may be better left where the G Fund lives.
The questions that decide it
Before making the decision, work out the answers to these:
- How much of your portfolio do you want in G Fund-type exposure, and can you replicate it elsewhere?
- What does your state offer for IRA creditor protection?
- Do you intend to run Roth conversions in the years before required distributions begin?
- What total cost would you pay in an IRA once fund expenses and any advisory fee are included?
- Does your withdrawal plan need asset-level control, or will installments serve?
Questions
Follow-ups we get asked.
No. You can leave your balance in the TSP indefinitely after separating from federal service. Required minimum distributions eventually apply, as they do to any tax-deferred account, but nothing forces you to move the account itself.
Yes. Partial rollovers are permitted, and this is a common approach: keeping a portion in the TSP for its cost and G Fund access while moving the rest to an IRA for withdrawal and tax flexibility.
A direct trustee-to-trustee rollover from a traditional TSP to a traditional IRA is not a taxable event. Converting to a Roth IRA is taxable, and that is a separate decision worth modeling rather than doing by default.
