A Solo 401(k), formally a one-participant 401(k) plan, can fund a physical precious metals position in two ways: a self-directed Solo 401(k) trust that holds IRS-eligible bullion directly, or a direct rollover into a self-directed IRA that holds the metal. For 2026, the elective deferral cap is 24,500 dollars and the overall 415(c) cap on annual additions is 72,000 dollars, with extra catch-up contributions at age 50 and above. This guide covers the Solo 401(k) mechanics self-employed owners and contractors actually need before they roll into a gold IRA, the qualifying events that allow a rollover, the comparison with the SEP IRA path, and the step-by-step process.
Can a Solo 401(k) roll into a gold IRA?
Yes, with a qualifying event such as reaching age 59 and a half (if the plan document allows in-service distributions), plan termination, or business closure. The cleanest path is a direct rollover to a self-directed traditional IRA at a custodian that supports IRS-eligible bullion under IRC Section 408(m)(3). A self-directed Solo 401(k) can also hold the metals directly without an IRA. A direct rollover is not a taxable event.
How a Solo 401(k) actually works
A one-participant 401(k) plan is a qualified retirement plan under Section 401(k) of the Internal Revenue Code, designed for a business owner with no full-time common-law employees other than a spouse (IRS One-Participant 401(k) Plans). The plan is sometimes called Solo 401(k), Solo-K, or Single-K. Each name describes the same vehicle. The owner wears two hats: as the employer of the business and as the employee participant.
The plan has two contribution streams flowing into the same trust. The employee elective deferral comes from the participant’s compensation through a written deferral election. The employer profit-sharing contribution comes from the business as a discretionary contribution. Combining the two is how a self-employed owner can fill the full Section 415(c) annual additions cap from a single income stream.
The plan document is the legal foundation. A custodian-provided prototype or a custom plan document defines the rules: eligibility, vesting (usually immediate for the owner), available contribution types, loan provisions, in-service distribution rights, Roth designated contributions, and permitted investments. The plan document choice determines whether the Solo 401(k) can hold IRS-eligible bullion directly inside the trust or must roll the balance to a self-directed IRA before metals can be acquired.
Solo 401(k) contribution rules and 2026 limits
For 2026, the IRS cost-of-living adjustments set the Solo 401(k) limits as follows (IRS COLA Increases for Dollar Limitations on Benefits and Contributions). The Section 402(g) employee elective deferral cap is 24,500 dollars. The age 50+ catch-up adds 8,000 dollars. The SECURE 2.0 super catch-up at ages 60, 61, 62, and 63 is 11,250 dollars in place of the regular catch-up. The Section 415(c) overall annual additions cap is 72,000 dollars, which excludes catch-up contributions. The Section 401(a)(17) compensation cap that limits the 25 percent profit-sharing calculation is 360,000 dollars.
| Limit | 2025 | 2026 |
|---|---|---|
| Employee elective deferral (Section 402(g)) | 23,500 dollars | 24,500 dollars |
| Catch-up contribution age 50+ | 7,500 dollars | 8,000 dollars |
| SECURE 2.0 super catch-up ages 60-63 | 11,250 dollars | 11,250 dollars |
| Overall 415(c) annual additions cap (excl. catch-up) | 70,000 dollars | 72,000 dollars |
| Compensation cap (Section 401(a)(17)) | 350,000 dollars | 360,000 dollars |
| Employer profit-sharing rate | Up to 25 percent of compensation | Up to 25 percent of compensation |


The mechanics differ for incorporated owners and unincorporated owners. An S corporation owner paid on W-2 wages can defer up to the full 24,500 dollar employee cap from W-2 wages, plus the corporation can contribute up to 25 percent of W-2 wages as the employer profit-sharing piece. An unincorporated sole proprietor uses a reduced effective rate because the contribution itself plus half of self-employment tax must be subtracted from earnings first. The IRS Publication 560 worksheet computes the exact figure (IRS Publication 560).
The total of employee deferrals plus employer profit-sharing across the Solo 401(k) cannot exceed the 415(c) cap of 72,000 dollars in 2026, ignoring catch-up. Catch-up amounts sit on top of that cap. An owner age 52 contributing the full 24,500 dollar deferral plus the 8,000 dollar catch-up plus 47,500 dollars of profit-sharing reaches 80,000 dollars total for the year, which is the 72,000 dollar cap plus the catch-up.
Why a Solo 401(k) allows broader investments than an employer plan
Standard employer 401(k) plans are administered by a third-party plan sponsor who selects the investment menu. Participants choose from a curated list of mutual funds, target-date funds, and sometimes a brokerage window. The plan sponsor’s fiduciary responsibility under ERISA, combined with the cost of vetting alternative investments, keeps most large-employer plans on a narrow menu. Physical precious metals are almost never offered.
A Solo 401(k) is different because the owner is the plan administrator and the only participant (or the only one besides a spouse). There is no third-party fiduciary curating a menu. The plan document is written, adopted, and signed by the owner. A self-directed plan document can permit IRS-eligible alternative investments under the general rules of qualified plan investing, subject to the prohibited transaction rules of Section 4975 and the precious metals rules of Section 408(m)(3) (26 U.S. Code Section 4975).
The practical investments available inside a properly drafted self-directed Solo 401(k) include physical gold, silver, platinum, and palladium bullion that meets the purity standards, real estate held by the trust, private mortgage notes, private placements in operating businesses (subject to UBIT considerations), and tax liens. The plan document must explicitly authorize each asset class, and the owner remains the trustee responsible for confirming each transaction is compliant.
The breadth comes with corresponding administrative weight. Prohibited transactions disqualify the entire plan if discovered. Disqualified persons (the owner, spouse, ancestors, descendants, and entities they control) cannot transact with the plan. Self-dealing rules are stricter than in a brokerage 401(k) because no third-party sponsor screens the trades. The combination of breadth and personal responsibility is the structural feature that distinguishes a self-directed Solo 401(k) from a corporate 401(k).
Qualifying events that allow a rollover
A Solo 401(k) is a qualified plan, so distribution and rollover rules follow Section 401(k) plan distribution events, not the more flexible IRA-to-IRA transfer rules. The owner is also the participant, but the participant’s right to take a distribution is still gated by the plan document’s distribution provisions. Four common qualifying events open the door to a rollover.
First is reaching age 59 and a half. If the plan document allows in-service distributions at 59 and a half, the participant can direct a partial or full rollover to a self-directed IRA while the Solo 401(k) plan remains active. The plan document language is the controlling rule. Some prototype plans default to allowing in-service at 59 and a half, others require an amendment.
Second is plan termination. The owner adopts a board resolution (or equivalent for an unincorporated business) to terminate the Solo 401(k) plan. The plan administrator distributes all balances to the participant, who can roll the amount into a self-directed IRA. A Solo 401(k) plan termination requires final-year Form 5500-EZ regardless of asset size and may carry administrative costs at the custodian.
Third is separation from service for owners who have a W-2 relationship with their own business. An S corporation owner whose business closes, or who stops paying themselves W-2 wages, has separated from service for plan purposes. The plan document distribution rules apply.
Fourth is business closure or dissolution. When the underlying business ceases operations, the Solo 401(k) participant can take a distribution and roll the balance under the plan’s terminating-event provisions. Practical timing depends on how the business form is wound down.
Solo 401(k) vs SEP IRA for precious metals
A self-employed person evaluating a precious metals retirement strategy has two main vehicles: a Solo 401(k) and a SEP IRA. Both can fund a self-directed metals position. The structural differences matter for owners with modest net earnings, for owners who want a Roth designated subaccount, and for owners who value administrative simplicity.
| Feature | Solo 401(k) (2026) | SEP IRA (2026) |
|---|---|---|
| Employee elective deferral | Up to 24,500 dollars | Not allowed |
| Catch-up contribution age 50+ | 8,000 dollars | Not applicable |
| SECURE 2.0 super catch-up ages 60-63 | 11,250 dollars (in place of regular catch-up) | Not applicable |
| Employer profit-sharing | Up to 25 percent of compensation | Up to 25 percent of compensation |
| Overall 415(c) cap (excl. catch-up) | 72,000 dollars | 72,000 dollars |
| Roth designated subaccount | Available if plan document allows | Not available in SEP itself |
| Loan feature | Yes, up to plan rules (50 percent of vested balance, 50,000 dollar ceiling) | No |
| Form 5500-EZ filing | Yes once assets exceed 250,000 dollars | No (model 5305-SEP) |
| Direct holding of physical metals | Yes if plan document permits self-direction | No (must roll to self-directed IRA first) |
| Best fit | Owners who want to maximize annual contributions at lower earnings or want Roth + loan | One-person shops with high net earnings and minimal paperwork tolerance |
The deferral component of a Solo 401(k) is the reason owners with modest net earnings often prefer it for ongoing contributions. A self-employed person netting 60,000 dollars can defer up to 24,500 dollars as an employee elective deferral plus a percentage as the employer profit-sharing contribution. The same person in a SEP IRA is limited to about 20 percent of net self-employment earnings, which translates to roughly 11,000 dollars at that income. The Solo 401(k) more than doubles the available contribution at that earnings level.
At higher earnings the two vehicles converge. An owner with 300,000 dollars of net earnings hits the 72,000 dollar 415(c) cap with either vehicle, ignoring the catch-up. At that income level the SEP IRA’s administrative simplicity (no Form 5500-EZ until later in life, no plan document maintenance) becomes the deciding factor for many owners.
The companion guide SEP IRA to gold IRA rollover covers the SEP-side mechanics in depth, and the mid-year SEP to Solo 401(k) switch guide covers the specific case of changing plan types within a tax year while keeping a metals allocation intact. For Roth-side metals, see the Roth Solo 401(k) to Roth gold IRA guide.
The rollover process step by step
The mechanics of moving a Solo 401(k) balance into a self-directed IRA holding physical precious metals follow the qualified plan to IRA rollover process described in IRS Rollovers of Retirement Plan and IRA Distributions. The cleanest method is a direct rollover, which moves the balance trustee-to-trustee without the participant taking constructive receipt and without triggering the mandatory 20 percent federal withholding that applies to indirect distributions from qualified plans.
Step one is confirming the qualifying event and the plan document’s distribution provisions. The owner reviews the plan document or the custodian prototype to verify that the distribution event (age 59 and a half in-service, plan termination, separation, or business closure) is supported and that the participant has the right to roll out the balance.
Step two is selecting the receiving custodian. The receiving custodian must support self-directed IRAs with precious metals. The participant opens a traditional self-directed IRA with that custodian and signs the new account paperwork, which establishes the IRA as ready to receive the incoming direct rollover. The custodian provides the routing details, the receiving account number, and a direct rollover request form.
Step three is initiating the direct rollover from the Solo 401(k). The plan administrator (the owner) processes a direct rollover to the receiving custodian. The check is made payable to the receiving custodian for the benefit of the participant, or the funds move by wire to the receiving custodian. Because the rollover is direct, no 20 percent withholding applies and no 1099-R distribution code triggers a tax event.
Step four is the metals purchase. Once the funds are in the receiving self-directed IRA, the participant directs the custodian to purchase eligible bullion from a precious metals dealer. The dealer’s invoice is paid by the custodian out of the IRA funds. The dealer ships the metal to an IRS-approved depository in the custodian’s name. The metals are held at the depository as an IRA asset.
Step five is documentation. The Solo 401(k) issues a Form 1099-R coded G for a direct rollover. The receiving custodian issues Form 5498 reporting the receipt. The participant retains these records for the tax file. No tax is owed for the year of a properly executed direct rollover.
Two paths: self-directed Solo 401(k) trust or self-directed IRA
Self-employed owners who want physical metals exposure can choose between two structures. The choice affects ongoing contributions, distribution flexibility, and administrative cost. Both structures hold IRS-eligible bullion under IRC Section 408(m)(3) (26 U.S. Code Section 408).
The first path is the self-directed Solo 401(k) trust holding the bullion directly. The Solo 401(k) plan document permits precious metals as an authorized investment. The plan trustee (the owner) purchases the metal in the name of the plan, and the metal is shipped to an IRS-approved depository in the trustee’s name. The Solo 401(k) keeps its qualified plan status, the participant continues to make annual contributions, and the metals sit inside the plan trust.
The second path is a direct rollover to a self-directed traditional IRA at a custodian that supports metals. The Solo 401(k) is either terminated, partially rolled at an in-service event, or fully rolled at a qualifying event. The metals are held at an IRS-approved depository in the IRA custodian’s name. The owner can keep an active Solo 401(k) for new contributions if the rollover was partial, or close the plan entirely if the rollover was full.
| Factor | Self-directed Solo 401(k) trust | Self-directed IRA (rollover destination) |
|---|---|---|
| Account type | Qualified plan trust | Individual retirement account |
| Trustee | The owner | The IRA custodian |
| Ongoing contributions | Yes, on full Solo 401(k) limits | Limited to standard IRA contribution caps |
| Loan feature | Yes, if plan document permits | No |
| Roth designated subaccount | Yes, if plan document permits | Separate Roth IRA only via conversion |
| UBIT exposure | Possible on leveraged real estate or active business holdings | Possible under same rules |
| Form 5500-EZ | Yes once plan exceeds 250,000 dollars | No |
| Prohibited transaction consequence | Plan disqualification (catastrophic) | IRA distribution treatment (severe) |
| Compliance complexity | Higher (owner is trustee) | Lower (custodian handles paperwork) |
A gold value calculator helps reconcile the dollar amount of the position with the spot value and premium of the chosen eligible products. Common eligible products include American Gold Eagle, American Gold Buffalo, Canadian Gold Maple Leaf, Austrian Gold Philharmonic, and bars from refiners on the LBMA Good Delivery list. The product choice has cost consequences because the premium over spot varies by product. The how to verify physical gold guide describes home tests and the limits of each, useful if the participant later takes an in-kind distribution.
The depository chosen by the trustee is part of the structure. Common IRS-approved depositories include Delaware Depository, Brink’s Global Services USA, and International Depository Services. The depository invoices annual storage fees through the trustee. Storage can be segregated (the trustee’s metal stored separately) or commingled (the trustee’s metal pooled with other clients’ metals of the same type). Segregated storage typically carries a higher fee.
Three scenarios for self-employed owners
The scenarios below illustrate the rules with hypothetical fact patterns common among Solo 401(k) participants. They are illustrative. They do not recommend a specific election. Tax outcomes depend on filing status, state of residence, other income, and timing. Consult your tax advisor and a licensed advisor before electing.
Scenario A: Independent contractor, age 56, with a 480,000 dollar Solo 401(k) balance
Anonymized profile based on a single-member LLC consultant. Solo 401(k) balance: 480,000 dollars, accumulated across nine years of contributions at a brokerage custodian. Current allocation: 70 percent equity index funds, 30 percent short-term Treasury fund. Net self-employment earnings this year: 220,000 dollars. The participant is 56, so the plan document’s in-service distribution age of 59 and a half does not yet apply.
The participant wants a 10 percent metals allocation but cannot roll out at this age without a qualifying event. The owner amends the Solo 401(k) plan document to authorize precious metals investments and converts the brokerage Solo 401(k) into a self-directed Solo 401(k) at a custodian that supports metals. The plan stays in place. Forty-eight thousand dollars of the existing balance is directed into American Gold Eagles and American Silver Eagles, shipped to Delaware Depository in the trustee’s name.
Annual contributions continue inside the same plan on the full Solo 401(k) limits. No taxable distribution occurs because no money left the plan. Form 5500-EZ is already required because the plan exceeds 250,000 dollars, so the change does not add a filing burden. The owner files the annual Form 5500-EZ each year going forward.
Scenario B: S corporation owner, age 62, planning to retire in 36 months
Anonymized profile based on a single-shareholder S corporation owner. Solo 401(k) balance: 920,000 dollars. Current W-2 wages from the S corporation: 140,000 dollars. The owner plans to retire and wind down the S corporation at age 65.
The owner wants a 15 percent metals allocation and prefers the simplicity of a self-directed IRA over a self-directed Solo 401(k) plan. The plan document allows in-service distributions at age 59 and a half. The owner takes a 138,000 dollar in-service partial direct rollover to a newly opened self-directed traditional IRA at a custodian that supports metals. The remaining 782,000 dollars stays in the Solo 401(k) for continued W-2 deferrals and employer profit-sharing.
The self-directed IRA directs 138,000 dollars into a mix of American Gold Eagles, American Gold Buffalos, and Austrian Silver Philharmonics. At the SECURE 2.0 super catch-up age range, the owner can also contribute up to 11,250 dollars of catch-up to the Solo 401(k) plus the regular deferral plus the employer profit-sharing piece, up to the 415(c) cap. At plan termination at age 65, the remaining Solo 401(k) balance can be rolled to the same self-directed IRA in a full direct rollover.
Scenario C: Contractor, age 48, with a former-employer 401(k) and a new Solo 401(k)
Anonymized profile based on a contractor who left a corporate job and started a single-owner consulting LLC. Former-employer 401(k) balance: 260,000 dollars. New Solo 401(k) opened this tax year. The participant is 48, so no in-service distribution is available, but the former-employer 401(k) is rollover-eligible because the participant separated from service.
The participant wants to consolidate retirement assets and add a metals position. Two paths are open. Path one: direct rollover of the former-employer 401(k) into the new Solo 401(k), then operate the Solo 401(k) as a self-directed plan that authorizes precious metals. Path two: direct rollover of the former-employer 401(k) into a self-directed traditional IRA that holds metals, keeping the Solo 401(k) for ongoing deferrals only.
Path one keeps everything inside the Solo 401(k) and preserves the loan feature on the consolidated balance, but adds Form 5500-EZ once the combined balance exceeds 250,000 dollars and requires a self-directed plan document. Path two keeps the Solo 401(k) as a clean prototype plan, isolates the metals position in a self-directed IRA, and avoids the Form 5500-EZ trigger on the metals piece. Either path is permitted. Consult your tax advisor for the structure that fits.
Tax pitfalls to avoid
Four pitfalls show up most often when Solo 401(k) balances move into self-directed structures. The first is rolling out of the Solo 401(k) without a qualifying event. The plan document’s distribution provisions are the legal gate. An owner who liquidates the plan account at a brokerage and moves the funds without an in-service or termination event creates an unauthorized distribution that the IRS can treat as a taxable distribution plus a 10 percent early distribution tax under Section 72(t) if the participant is under 59 and a half.
The second pitfall is the 20 percent mandatory federal withholding on indirect distributions from qualified plans. If the Solo 401(k) distributes funds directly to the participant rather than to the receiving custodian, 20 percent is withheld and remitted to the Treasury. The participant has 60 days to deposit the gross (pre-withholding) amount with the receiving custodian to avoid tax. Making up the 20 percent from other personal funds is the only way to roll the full amount; otherwise the 20 percent becomes a taxable distribution. A direct trustee-to-trustee rollover avoids the withholding entirely.
The third pitfall is rolling an RMD by mistake. Once the participant reaches the applicable RMD age (73 under SECURE Act 2.0 for those born 1951 through 1959, rising to 75 for those born in 1960 or later), the Solo 401(k) must distribute the calculated RMD for the year. The RMD itself is not rollover-eligible. Rolling the RMD into a new IRA creates an excess contribution in the receiving IRA, subject to a 6 percent excise tax per year until corrected (IRS Publication 590-B).
The fourth pitfall is purchasing IRA-prohibited or plan-prohibited metals or coins. Collectible coins outside the IRC Section 408(m)(3) carve-outs are not eligible inside an IRA or a Solo 401(k). Purchasing such a product produces a deemed distribution of the entire amount used to buy the disqualified asset (IRS Publication 590-A). The participant owes income tax on the deemed distribution and may owe the 10 percent early distribution tax. The custodian and dealer should both confirm eligibility before purchase, but the participant remains responsible.
