Principal Financial 401(k) Rollover to IRA: Process, SimpleInvest Fees, and When to Stay (2026)

Principal Financial Group is one of the largest retirement plan recordkeepers in the United States, serving approximately 10 million active defined-contribution plan participants — primarily through small- and mid-size employers. If your workplace 401(k), 403(b), or 457 plan is administered by Principal, you have more flexibility on rollover than many participants realize: you can roll to a Principal rollover IRA (staying within the platform), to Fidelity, Vanguard, or Schwab (for lower fund costs), or to your new employer's plan. The right move depends on four factors this guide walks through in detail.

Principal occupies the same dual-role position as T. Rowe Price and Merrill Lynch: it is simultaneously a 401(k) recordkeeper for your employer's plan and an IRA custodian for individual accounts. That overlap means rolling within Principal is sometimes faster and simpler — but it also means Principal has an incentive to capture your rollover assets, including upselling their SimpleInvest managed account at 0.85% per year. Understanding whether that fee is appropriate for your situation — or whether a self-directed IRA at a lower-cost custodian makes more sense — is the central financial decision of a Principal rollover.

Principal Financial's dual role: recordkeeper and IRA custodian

Rolling your Principal 401(k) to a Principal IRA keeps everything within the same platform, can simplify the transfer, and gives you access to their SimpleInvest managed account or self-directed options. Rolling to Fidelity, Vanguard, or Schwab means more paperwork and a 2–4 week wait — but typically unlocks access to index funds with lower expense ratios than what Principal's fund lineup offers. The cost math should drive this decision, not convenience.

Four rollover paths from a Principal Financial 401(k)

Step-by-step: how to roll your Principal Financial 401(k) to an IRA

Step 1 — Decide where you're rolling

If you're rolling to a different custodian (Fidelity, Vanguard, Schwab), open the receiving IRA account before contacting Principal. You'll need the receiving account number and the custodian's mailing address for the check. See best rollover IRA account 2026 for a side-by-side cost comparison. If you're rolling within Principal (to a Principal rollover IRA), open the receiving IRA at principal.com first.

Step 2 — Log in to principal.com and initiate the distribution

Log in to your Principal workplace retirement account at principal.com. Navigate to your plan account and look for distribution or rollover options. Many Principal-administered plans allow online rollover initiation. If your plan does not offer online self-service distributions, call Principal at 1-800-547-7754 to initiate the rollover by phone or request a distribution form.¹

Step 3 — Specify "direct rollover"

Always request a direct rollover — the check is made payable to your new custodian FBO (for benefit of) your name, not to you personally. A direct rollover avoids the mandatory 20% federal income tax withholding that applies to indirect rollovers under IRC § 3405(c). If the check is made payable to you instead, 20% is withheld and you must replace that amount from other funds within 60 days to avoid a taxable event. See 60-day rollover rule guide for details on the withholding trap.

Step 4 — Provide receiving-account information

For external rollovers: provide the receiving custodian's name, mailing address, and your IRA account number. Principal will mail a check payable to the receiving custodian FBO you. For same-firm Principal rollovers: typically only your Principal IRA account number is needed. Note that balances above $250,000 may require a Medallion Signature Guarantee depending on the plan document — confirm with Principal before submitting your request.

Step 5 — Handle any outstanding 401(k) loan

If you have an outstanding loan against your Principal 401(k), it must be repaid before rolling over — or it becomes a taxable distribution (a "plan loan offset"). If the offset qualifies as a QPLO (Qualified Plan Loan Offset) under IRC § 402(c)(3)(C), you have until the tax filing deadline including extensions — typically October 15 of the following year — to roll the offset amount in cash to an IRA and avoid the tax. See 401(k) loan offset rollover guide.

Step 6 — Monitor and confirm receipt

Same-firm Principal rollovers may complete more quickly than the 2–4 week external timeline. External rollovers typically take 7–10 days at Principal to process the check, plus transit time and 3–5 days at the receiving custodian. If funds have not arrived within 25 business days, contact Principal to confirm the check was issued and obtain tracking information. Request a stop-payment and reissue if necessary — do not miss the 60-day window for indirect rollovers.

Principal's IRA fee structure: three options

Once your Principal 401(k) money is rolling to a Principal IRA, you'll choose among three product types:

The SimpleInvest 0.85% all-in wrap fee is the product Principal most commonly promotes to rollover participants. Unlike T. Rowe Price's Retirement Advisory Service (which charges ~0.50% plus underlying fund ERs for a total around 0.65–0.85%), SimpleInvest bundles everything into the 0.85% figure — advisory, funds, and most transaction costs. That transparency is useful, but the absolute cost is still high compared to self-managing in a low-cost index fund IRA.²

The FDIC-insured IRA through Principal Bank is appropriate only if your goal is capital preservation in retirement (e.g., the IRA is already in distribution). For a rollover investor who needs 10–20+ years of growth, placing $500,000 in a savings vehicle earning CD-like rates is a large opportunity cost.

Fee comparison: Principal SimpleInvest vs. self-managed rollover IRA

The 0.85% gap between SimpleInvest and a self-managed index fund IRA at Vanguard (VTI, 0.03%) compounds significantly over time. The calculator below shows the difference.

When to keep the Principal 401(k) instead of rolling

Four situations make a strong case for leaving your balance in the Principal plan rather than rolling to an IRA:

1. You are between ages 55 and 59½ (Rule of 55)

If you separate from service at or after age 55 (50 for qualified public safety employees), you can take penalty-free withdrawals from that employer's 401(k) under IRC § 72(t)(2)(A)(v). This access disappears the moment you roll the balance to an IRA — even a rollover IRA at Principal. The Rule of 55 applies only to the employer plan you were participating in when you separated; an IRA has no equivalent rule. If you need income between ages 55 and 59½, keeping the Principal plan open preserves that access. See leave-401k-vs-rollover decision guide for a full analysis and checklist.

2. You are actively doing backdoor Roth conversions

Rolling a pre-tax Principal 401(k) into a traditional IRA contaminates your IRA pool for the pro-rata rule. If you currently have zero (or near-zero) pre-tax IRA balance and make annual backdoor Roth contributions, adding pre-tax 401(k) money to your IRA substantially increases the taxable portion of every future backdoor Roth conversion. The fix: roll to your new employer's 401(k) (if it accepts incoming rollovers) or leave the balance in the Principal plan. See reverse rollover guide if you've already rolled to an IRA and want to fix the pro-rata problem.

3. Your plan holds employer stock with NUA potential

If your Principal 401(k) holds employer stock with a low original cost basis, rolling all of it to an IRA permanently forfeits the Net Unrealized Appreciation (NUA) tax break under IRC § 402(e)(4). The NUA strategy requires a lump-sum distribution from the plan — not a rollover — and converts ordinary-income tax on highly appreciated stock into long-term capital gains rates. Once the stock is inside a rollover IRA, it is taxed as ordinary income on every future withdrawal. See NUA employer stock guide and the NUA calculator before rolling any employer stock.

4. Unlimited ERISA creditor protection matters to you

Assets inside an employer 401(k) have unlimited federal creditor protection under ERISA — no cap. A rollover IRA has a bankruptcy exemption of $1,711,975 per person (effective April 2025, BAPCPA 11 U.S.C. § 522(n)), and state-law non-bankruptcy creditor protections vary widely. For high-net-worth professionals with litigation exposure — physicians, attorneys, executives — the gap between unlimited and $1.7M protection can be significant. Rolling to a new employer's 401(k) restores unlimited ERISA protection; rolling to an IRA (at Principal or anywhere else) does not.

Tax rules for the Principal 401(k) rollover

• No income tax on a direct rollover. Principal sends funds directly to the IRA custodian (or issues a check payable to the custodian FBO you) under IRC § 402(c). No income tax is triggered on any balance, at any age.
• No early withdrawal penalty. A direct rollover to an IRA incurs no 10% penalty even if you are under 59½. The penalty applies to actual distributions, not to rollovers.
• Form 1099-R Code G. Principal issues a Form 1099-R at year-end with Code G (direct rollover). Report on your tax return; no tax is owed on the rollover amount.
• Roth 401(k) portion. If your Principal plan contains Roth 401(k) contributions, those roll tax-free to a Roth IRA. The Roth 401(k)'s 5-year holding period does not carry over to the Roth IRA — the Roth IRA's own clock (starting from your first Roth IRA contribution of any kind) governs when earnings become tax-free. See Roth 401(k) to Roth IRA rollover guide.
• After-tax (non-Roth) basis. If your Principal plan permitted after-tax contributions beyond the Roth 401(k) option, IRS Notice 2014-54 lets you split the rollover: after-tax basis rolls to a Roth IRA tax-free; pre-tax earnings roll to a traditional IRA. See after-tax 401(k) split rollover guide.
• IRMAA cliff warning. If you convert any portion to Roth in the rollover year, a large conversion can push MAGI past the 2026 Medicare IRMAA Tier 1 threshold ($109,000 single / $218,000 MFJ — IRS Rev. Proc. 2025-32), adding a Medicare Part B surcharge. Check with the Roth conversion calculator before converting.

RMD sequencing if you are 73 or older

If you've reached RMD age — 73 for those born 1951–1959; 75 for those born 1960 or later under SECURE 2.0 § 107 — you must take your Required Minimum Distribution from the Principal plan before rolling the remaining balance. IRC § 408(d)(3)(E) bars rolling RMD amounts into an IRA. Principal will typically prompt you about this during the distribution process, but the tax obligation is yours. Rolling an RMD into an IRA makes it an excess contribution, triggering a 6% excise tax per year it remains in the account. Take the RMD first, then initiate the rollover on the remaining balance. See IRA rollover RMD rules guide.

Principal SimpleInvest vs. a fee-only financial advisor

Principal actively promotes SimpleInvest to rollover participants. It offers genuine value for investors who want hands-off management and don't want to select or rebalance their own portfolio. But it is not the same as working with a fiduciary fee-only advisor:

For straightforward investment management, SimpleInvest at 0.85% is functional but not cheap. For the planning decisions that have the largest financial impact at rollover time — NUA, Roth conversion window, pro-rata rule analysis — SimpleInvest does not provide the guidance that matters most. See how to choose an IRA rollover advisor for the evaluation framework.

After the rollover: first steps

1. Update beneficiary designations. Your Principal 401(k) beneficiary designation does not carry over to your IRA. Log in to the IRA custodian immediately — whether Principal or another firm — and add primary and contingent beneficiaries. The IRA passes outside your will; whatever designation is on file controls. See IRA beneficiary designations guide.
2. Evaluate a Roth conversion window. The year of a job change — before new-employer income resumes — is often the lowest-income-tax year in a career. If your marginal bracket temporarily drops to 12% or 22%, a partial Roth conversion of the rollover IRA locks in lower taxes permanently. Model the bracket and IRMAA exposure with the Roth conversion calculator.
3. Choose investments deliberately. Whether you roll to Principal or another custodian, fund selection determines your long-run outcome more than almost any other post-rollover decision. The expense ratio difference between 0.85% and 0.03% compounds to tens of thousands of dollars over 20 years. See asset location after rollover for a framework on placing the right assets in the right accounts.
4. Track Form 8606 if you have after-tax basis. If the Principal plan had after-tax (non-Roth) contributions that rolled to a traditional IRA, that creates non-deductible IRA basis tracked on Form 8606. File 8606 in the rollover year and every year you take distributions. See non-deductible IRA guide.

When a fee-only advisor adds the most value

Most Principal 401(k) rollovers are straightforward. Expert help is worth the time in these situations:

• Employer stock with NUA potential. One-time, irrevocable election. Calculate the break-even before rolling any stock into an IRA.
• Pro-rata rule contamination risk. If you actively do backdoor Roth conversions, every dollar of pre-tax money entering your IRA increases annual tax cost. Quantify this before rolling.
• Ages 55–59½ with income needs. Giving up Rule of 55 access is irreversible. Model whether you need that access before rolling.
• Large balance with Roth conversion opportunity. A $500K+ rollover IRA with 10+ years before RMDs has significant conversion potential — the difference between a planned and unplanned strategy over that window can exceed $100,000 in lifetime after-tax wealth.
• Evaluating SimpleInvest. If you're seriously considering the 0.85% managed option, compare it against a fee-only advisor who charges a flat planning fee plus self-managed index funds — the total cost is often lower with better planning depth.
