Trustee-to-Trustee Transfer Rules for TSP Rollovers
A trustee-to-trustee transfer is a movement of retirement assets directly between two financial institutions acting as trustees or custodians, with no distribution to the account holder at any point. The term is used in IRS guidance to describe both IRA-to-IRA direct transfers and direct rollovers from qualified plans to IRAs — emphasizing that the funds flow institution-to-institution without passing through the participant's hands. This guide explains how the Trustee-to-Trustee Transfer applies specifically to TSP accounts — including IRS mechanics, withholding rules, deadlines, and step-by-step instructions.
1How the Trustee-to-Trustee Transfer Works
The term 'trustee-to-trustee transfer' is used in IRS Publication 590-A to describe the cleanest form of IRA movement. In practice, it encompasses two distinct mechanics: (1) For IRA-to-IRA: the receiving custodian sends a transfer request to the sending custodian — no participant action beyond signing the transfer form. (2) For qualified plan to IRA: the plan administrator issues payment to the new IRA custodian directly — the participant provides the custodian's FBO details. In both cases, the defining feature is that funds never enter the participant's bank account or personal possession.
Method Profile — Trustee-to-Trustee Transfer
- Legal Classification
- For IRA-to-IRA: non-reportable transfer (no Form 1099-R, no Form 5498 rollover entry). For qualified plan to IRA: direct rollover (Form 1099-R Code G, Form 5498 rollover entry). Both involve funds moving institution-to-institution with no participant access.
- Also Known As
- Direct Transfer, Institution-to-Institution Transfer, Custodian-to-Custodian Transfer, Direct Rollover (when from qualified plan to IRA)
- Funds Pass Through You
- No — institution-to-institution

The trustee-to-trustee transfer is the IRS's ideal mechanism for retirement asset portability — the system it built to allow participants to move money freely between institutions without creating taxable events, withholding complications, or administrative deadlines. The fact that it is underused relative to indirect rollovers reflects a gap in participant education, not a gap in the mechanism itself. Understanding the difference between a trustee-to-trustee transfer and an indirect rollover is arguably the single most valuable piece of retirement account procedural knowledge a participant can have.
2TSP — Specific Considerations
Separation from federal service (retirement, resignation, or removal), or reaching age 59½ while still employed (for in-service withdrawals). Special rules apply for required minimum distribution age.
Rollover Deadline
60 Days
TSP direct rollovers are processed through the TSP's own distribution form (Form TSP-70 for full withdrawal or TSP-77 for partial). The TSP is administered by the FRTIB — not a commercial custodian — and has its own processing queue. Allow 7–10 business days for the TSP to process the request after receiving complete paperwork.
Tax Treatment
pre-tax (traditional) or post-tax (Roth TSP)
Traditional TSP: pre-tax. Roth TSP: after-tax. Both can exist in the same account.
Early Withdrawal Penalty
10% federal penalty
10% federal penalty plus ordinary income tax for distributions before age 59½
RMD Start Age
Age 73
The TSP calculates and processes RMDs automatically for participants who have not yet taken a distribution by their required beginning date. This automatic processing is a feature unique to the TSP — commercial IRA custodians do not automatically distribute RMDs.
The TSP is the largest defined-contribution retirement plan in the world, with over $900 billion in assets as of 2025. It offers some of the lowest expense ratios available to any retirement investor — the G Fund (government securities) has an expense ratio of approximately 0.04%, compared to the industry average of 0.45%. Despite these advantages, the TSP's limited fund menu (only 5 core index funds plus L Funds) is the primary reason federal retirees roll to an IRA — for broader investment options, including Self-Directed IRA alternatives.
Federal employees can access their TSP after separation from service at any age. Retired military members have separate TSP access rules. Civilian FERS employees who separate after age 55 avoid the 10% early withdrawal penalty — a one-year advantage over the standard age 59½ threshold that applies to IRAs and most other qualified plans.
3Withholding Rules
✅ Withholding Bypass
No Mandatory Withholding — 0% — the trustee-to-trustee mechanism fully bypasses federal and state withholding in all its forms
The withholding bypass is structural — because funds never pass to the participant, the legal trigger for withholding under IRC Section 3405 never occurs. This applies whether the transfer is IRA-to-IRA (no reporting at all) or qualified plan to IRA (direct rollover with Code G — no withholding required).
4Step-by-Step Rollover Process
Follow these steps to execute a Trustee-to-Trustee Transfer from a TSP correctly and avoid common errors.
⏱ Typical Timeline
IRA-to-IRA: 3–10 business days. Qualified plan to IRA: 7–21 business days depending on plan administrator.
5Best Use Cases vs. When to Avoid
Ideal For
Moving an IRA from any custodian to any other custodian — the default, preferred mechanism
Ideal For
Rollover from a qualified plan (401k, TSP, 403b) to an IRA — the direct rollover form of trustee-to-trustee
Ideal For
Consolidating multiple IRAs from different custodians into a single account
Ideal For
Moving assets to a self-directed IRA custodian for alternative investments
Ideal For
Any movement where the participant wants zero IRS footprint and no withholding
Not Ideal For
Roth conversions (traditional-to-Roth) — those are taxable events regardless of transfer method
Not Ideal For
Assets held in non-transferable formats (some annuities must be surrendered rather than transferred)
Federal employees who contributed to both FERS (the pension) and the TSP have a layered retirement income structure. The TSP rollover decision is often driven by the desire to hold alternative assets — Gold IRAs, real estate IRAs — that are not available within the TSP's index fund menu.
6Common Mistakes to Avoid
Accepting a distribution check even when a trustee-to-trustee transfer was intended
Some plan administrators default to issuing a check even when the participant requests a direct rollover — particularly smaller employer plans and older 401(k) platforms. If you receive a check in your name (not in the new custodian's name FBO you), contact both institutions immediately. You may be able to return the check and have it reissued correctly. If you deposit it, you are in a 60-day indirect rollover with 20% already withheld.
Initiating a transfer from the sending institution instead of the receiving institution
For IRA-to-IRA transfers, the transfer request should always be initiated by the receiving custodian — they send the transfer request to the sending institution. If you call the sending institution and ask them to 'send the funds' to the new custodian, they may issue a distribution check rather than a transfer. Always initiate from the receiving end using the receiving custodian's Transfer Request Form.
Assuming the trustee-to-trustee mechanism works for Roth conversions
A traditional-to-Roth conversion cannot be executed as a non-taxable transfer, regardless of how the mechanics are structured. If you initiate what you believe is a 'trustee transfer' from your traditional IRA to a Roth IRA, the pre-tax amount is a taxable conversion in the year of transfer. The trustee-to-trustee mechanism does not change the tax character of the transaction — it only determines whether funds pass through the participant's hands.
The TSP is governed by FERSA and administered by the Federal Retirement Thrift Investment Board (FRTIB), an independent government agency. Unlike commercial 401(k) plans, the TSP is not subject to ERISA — it operates under federal statute. Rollovers from the TSP are governed by IRC Section 402(c) and IRS Notice 2009-68.
7Frequently Asked Questions
What is a trustee-to-trustee transfer and is it the same as a direct rollover?
They are similar but not identical. A trustee-to-trustee transfer is IRA-to-IRA movement with no IRS reporting — completely invisible to the tax system. A direct rollover is a qualified plan (401k, TSP) to IRA movement that generates a Form 1099-R with Code G — reportable but non-taxable. Both avoid the 20% withholding and the 60-day deadline. The trustee-to-trustee transfer is the cleaner mechanism with zero tax footprint.
Does a trustee-to-trustee transfer count against my one rollover per year limit?
No — the one-rollover-per-12-months limit applies only to 60-day indirect IRA rollovers. Trustee-to-trustee transfers are explicitly excluded from this limitation. You can execute unlimited trustee-to-trustee transfers in a single year across all your IRA accounts.
Can a trustee-to-trustee transfer be done from a 401(k) directly to a Roth IRA?
Yes — a direct rollover from a traditional 401(k) to a Roth IRA is permitted and can be structured as a trustee-to-trustee movement. However, the pre-tax amount is fully taxable as a Roth conversion in the year of transfer — the trustee-to-trustee mechanism does not eliminate the tax. It only eliminates the withholding and the 60-day deadline. You will owe income tax on the converted amount at filing.
Does the one-rollover-per-year rule apply to TSP Trustee-to-Trustee Transfers?
No — the one-rollover-per-12-months limitation does not apply to the Trustee-to-Trustee Transfer. The one-rollover-per-12-months rule was specifically designed to limit 60-day indirect rollovers — it has no application to trustee-to-trustee transfers. This distinction is codified in IRS Announcement 2014-15, which clarifies that trustee-to-trustee transfers between IRA custodians are excluded from the limitation.
What IRS form is generated when I use the Trustee-to-Trustee Transfer for my TSP?
IRA-to-IRA: no forms generated. Qualified plan to IRA: Form 1099-R Code G + Form 5498 rollover entry.
