Rollover comparison
Principal → Vanguard 401(k) rollover
If you're rolling a 401(k) FROM Principal TO Vanguard, here are the practical mechanics: what forms you'll fill out, how long it takes, whether ACATS is supported, and what specific gotchas to watch for at each custodian. This page documents the process; it does not recommend one custodian over the other.
Side-by-side

Known pitfalls at Principal
Warning: Principal specializes in small-business 401(k) plans, so rollover forms are highly plan-specific — you can't always download a generic form from the website. Call your former employer's HR to ask which form their plan uses.
Warning: Many Principal plans require a Medallion Signature Guarantee for rollovers over $50K (NOT a notary). Get this in person at a bank you have a relationship with before you start — finding a Medallion provider can take a couple days.
Warning: Principal will sometimes ask the destination custodian to provide a 'Letter of Acceptance' on letterhead. Request this from the destination upfront (they all have a standard form) — saves a callback.
Known pitfalls at Vanguard
Warning: Vanguard's outbound-transfer form is at 'Profile & account settings → Move money out → To another firm'. It's easy to miss — they bury it deeper than other custodians.
Warning: If your 401(k) is at Vanguard Retirement Plan Services (employer plan), the path is different — log into Vanguard.com/retirementplans, not my.vanguard.com.
Warning: Vanguard requires a Medallion Signature Guarantee for transfers over $100K (NOT a notary — a Medallion stamp, typically from a bank you have a relationship with). Get this in person before you start; finding a Medallion provider can take a couple days.

- How long does a Principal to Vanguard 401(k) rollover take?
- Principal uses a paper-based transfer process (10-14 business days; Medallion stamp may be required), while Vanguard supports ACATS. Despite Vanguard's ACATS capability, the outbound process is controlled by Principal, so expect 10-14 business days; Medallion stamp may be required from the date you submit your rollover form.
- Do I call Principal or Vanguard first to start the rollover?
- Call Principal first at 1-800-547-7754 to request the rollover form and confirm the direct-rollover process. Once you have the form, call Vanguard to confirm they accept incoming rollovers from Principal and get any required receiving documentation.
- Will I owe taxes when rolling over from Principal to Vanguard?
- A direct trustee-to-trustee rollover from a traditional 401(k) to a traditional IRA or new 401(k) is NOT a taxable event — provided funds move custodian-to-custodian and are never paid to you personally. No federal or state income tax, no 10% early-withdrawal penalty. If you're rolling into a Roth IRA (conversion), the pre-tax balance does become taxable income for the year of conversion — that's a deliberate tax election, not a mistake. Request "direct rollover" language explicitly with Principal so the 1099-R is coded Box 7 = G (direct rollover) rather than Box 7 = 1 or 2 (distribution), which would incorrectly trigger withholding and IRS scrutiny.
- Does Principal charge a fee to roll over my 401(k)?
- Most employer 401(k) plans administered by Principal do not charge an outbound rollover fee, but some employer plan documents do include a distribution or processing fee ($25–$75 is common). Check your Summary Plan Description (the document your former employer sent when you joined the plan) — the fee schedule is in there — or ask the Principal rep when you call (1-800-547-7754). Principal may also liquidate any holdings that can't transfer in-kind before sending, so you could face a brief period out of the market during the transfer.
- What's the 60-day rule for a Principal to Vanguard rollover?
- If you received a check made out to you (an indirect rollover), you have exactly 60 calendar days from the date of distribution to deposit the full gross amount — including the 20% the custodian withheld — into a qualifying retirement account. If you initiate a direct trustee-to-trustee transfer instead (the recommended path), the 60-day clock does not apply because you never receive the funds personally. For direct transfers, initiate immediately — Principal's processing time is 10-14 business days; Medallion stamp may be required, which can consume a significant portion of your window if you wait.
- Can I roll my Principal 401(k) into a Vanguard IRA directly?
- Yes — a direct rollover from a Principal 401(k) to a Vanguard traditional IRA is fully legal under IRC §402(c). Vanguard supports ACATS, so the cleanest path is to open the IRA at Vanguard first, then have Vanguard initiate an ACATS pull from Principal. The one exception: if your Principal 401(k) contains employer stock with significant appreciation, review Net Unrealized Appreciation (NUA) tax treatment with a CPA before rolling — NUA elections must be made at the time of distribution and cannot be undone.
