A Solo 401k rollover typically costs $0–$150 in administrative fees and takes 3–10 business days to complete. You can roll over funds tax-free into a Traditional IRA, a new Solo 401k, or a standard 401k without triggering penalties, as long as you complete the transfer within 60 days or use a direct rollover method.

What Does a Solo 401k Rollover Actually Cost?
One of the most common questions self-employed individuals ask is whether rolling over a Solo 401k is expensive. The good news: in most cases, the out-of-pocket costs are minimal. However, there are several fee categories worth understanding before you initiate the process.
Outgoing Transfer Fees
Many Solo 401k custodians charge an outgoing transfer or account termination fee ranging from $0 to $150. Some providers — particularly newer, online-first platforms — waive this entirely. Traditional brokerage firms may charge $50–$100 to process the paperwork and liquidate holdings. Always check your plan documents or call your custodian directly to confirm before initiating a rollover.
Account Closure or Plan Termination Fees
Because a Solo 401k is a plan — not just an account — closing one may require filing IRS Form 5500-EZ if your plan had more than $250,000 in assets at the end of the previous plan year. Filing this form is free, but working with a CPA or third-party administrator (TPA) to handle termination paperwork can cost $300–$800 depending on complexity.
Receiving Institution Fees
The account you’re rolling into may also charge setup or incoming transfer fees, though many major custodians such as Fidelity, Vanguard, and Charles Schwab charge $0 for incoming rollovers. If you’re opening a new Solo 401k at a different provider, ask specifically about plan setup fees, which can range from $0 to $500 annually.
Potential Tax Costs if Done Incorrectly
If your rollover becomes an indirect rollover (meaning the funds are distributed to you personally), your custodian is required to withhold 20% for federal taxes. You must deposit 100% of the original distribution — including the withheld amount — into the new account within 60 days to avoid it being treated as a taxable distribution. Failing to do so triggers income tax plus a 10% early withdrawal penalty if you’re under age 59½. Use our Early Withdrawal Penalty Calculator to see exactly what that could cost you.
Step-by-Step: How the Solo 401k Rollover Process Works
Understanding the mechanics of a Solo 401k rollover helps you avoid costly mistakes and unnecessary delays.
Step 1: Confirm Rollover Eligibility
You must have a triggering event to roll over a Solo 401k. Common qualifying events include ceasing self-employment activity, turning 59½, or closing your business entirely. If you’re still actively self-employed, you generally cannot roll the funds out while the plan remains active.
Step 2: Choose Your Destination Account
Your Solo 401k funds can move to:
- Traditional IRA — the most common destination; no taxes due at the time of transfer
- Another 401k plan — if you become employed and your new employer’s plan accepts rollovers
- A new Solo 401k — if you’re switching providers but remain self-employed
- Roth IRA — this is a taxable conversion event, and you’ll owe income tax on the pre-tax portion rolled over
Step 3: Choose Direct vs. Indirect Rollover
A direct rollover (also called a trustee-to-trustee transfer) is the safest method. Funds move directly between institutions, no withholding occurs, and there’s no 60-day deadline to worry about. An indirect rollover sends a check to you personally — you then have 60 days to deposit the funds into the new account. This method carries more risk and the 20% withholding requirement applies automatically.
Step 4: Complete the Paperwork
Both the sending and receiving institutions will require rollover request forms. Processing typically takes 3–10 business days for electronic transfers and up to 3–4 weeks if the custodian issues a paper check. Request a confirmation number and follow up if funds haven’t moved within 7 business days.
Step 5: File Required IRS Forms
After the rollover is complete, you’ll receive a Form 1099-R from the distributing custodian. You must report this on your federal tax return, even if no taxes are owed. The receiving institution will issue a Form 5498 confirming the rollover contribution. Keep copies of both for your records.
State Tax Considerations for Solo 401k Rollovers
Most states follow federal tax treatment for direct rollovers — meaning a properly executed rollover is not subject to state income tax at the time of transfer. However, there are important exceptions:
- States with no income tax (Florida, Texas, Nevada, Washington, etc.): No state tax applies to any retirement distribution.
- California: Requires a 2% state withholding on distributions unless you opt out. A qualifying rollover is exempt, but you must submit the correct exemption certification.
- New York: Rollovers to qualified retirement accounts are generally exempt from state tax if properly documented.
- Mandatory withholding states: Some states, including Vermont and Maine, require mandatory state withholding on retirement distributions unless documentation of a qualifying rollover is provided upfront.
Always verify current withholding requirements with your state’s department of revenue or a tax professional, as rules can change year to year.

Frequently Asked Questions
How long does a Solo 401k rollover take?
Most direct rollovers complete within 3–10 business days when done electronically. Paper check rollovers can take 3–4 weeks. If you’re closing the plan entirely, account for additional time for plan termination paperwork, which can extend the process by several weeks.
Is there a fee to roll over a Solo 401k?
Outgoing transfer fees range from $0 to $150 depending on your custodian. Plan termination services through a CPA or TPA can add $300–$800. The receiving institution often charges nothing for an incoming rollover. Always ask both institutions for a complete fee schedule before initiating the process.
Can I roll my Solo 401k into a Roth IRA?
Yes, but it is a taxable event. The pre-tax portion of your Solo 401k will be added to your ordinary income for the year of conversion and taxed at your marginal federal and applicable state rate. There is no early withdrawal penalty, but the tax bill can be significant. Use the Traditional vs Roth IRA Calculator to model the cost.
What happens if I miss the 60-day rollover deadline?
If you received an indirect distribution and fail to deposit the full original amount into a qualifying account within 60 days, the entire distributed amount becomes taxable income. If you’re under 59½, you’ll also owe a 10% early withdrawal penalty. The IRS does allow hardship waivers in limited circumstances, but they are not guaranteed.
Do I need to file IRS Form 5500-EZ when I close a Solo 401k?
You must file Form 5500-EZ for the final plan year if your Solo 401k ever had more than $250,000 in assets at the end of any plan year. Even if the balance is below that threshold at closing, you may still need to file a final return. Check IRS instructions for Form 5500-EZ or consult a tax professional to confirm your specific obligation.
