Choosing where to open your retirement account matters more than most people realize, and the decision is different for self-employed people than it is for regular employees. A Solo 401k or SEP-IRA is only as good as the brokerage holding it, and the differences between the major platforms on fees, Roth availability, loan options, and investment selection are real enough to affect your long-term outcome.
This guide compares the strongest brokerage options for self-employed people specifically in 2026, covering both the retirement account infrastructure they offer and the broader investing experience around it.
Why Brokerage Choice Matters for the Self-Employed Specifically
A W-2 employee’s retirement account is usually set up by their employer through a plan provider they had no part in choosing. As a self-employed person, you choose the brokerage, set up the plan, make the contribution decisions, and handle the administrative requirements yourself. That means the platform you land on affects every part of the experience, not just the commission rate on stock trades.
The most important question for a freelancer choosing a brokerage is not which one has the best interface. It is which one offers the right account type with the right features for your situation. A brokerage that does not offer a Solo 401k with Roth contributions is a fundamentally different choice than one that does, because that difference affects how much you can save and how those savings are taxed over decades.
Fidelity, Schwab, and Vanguard are all strong choices for self-employed investors who need SEP-IRAs, SIMPLE IRAs, or Solo 401k plans. Robinhood does not offer these account types and should be avoided by self-employed individuals who want to maximize retirement contributions. Stephsbooks
The Account Types Self-Employed People Actually Need
Before comparing platforms, it helps to be clear about what you are looking for. Most self-employed people need access to one or more of the following: a Solo 401k for owner-only businesses, a SEP-IRA for flexibility and simplicity, a Roth or Traditional IRA as a supplemental account, and a taxable brokerage account for investing beyond retirement account limits.
Not every brokerage offers all of these, and not every brokerage’s Solo 401k is equally capable. The Roth deferral option inside a Solo 401k, the ability to take a loan from the plan, and whether the plan accepts rollovers from old employer accounts are features that vary significantly by provider and that affect how useful the account is in practice.
Fidelity: The Strongest All-Around Choice for Most Freelancers
Fidelity is the most consistently top-rated brokerage across independent review sources in 2026, earning the number one or two position in virtually every major category across Bankrate, NerdWallet, The College Investor, and Finder evaluations. InvoiceBloom
For self-employed people specifically, Fidelity’s Solo 401k plan checks most of the boxes that matter. It supports both traditional pre-tax and Roth contributions, accepts rollovers from old employer plans, has no setup or annual maintenance fee, and charges zero commission on stock and ETF trades. The plan also supports after-tax contributions, which opens the door to the Mega Backdoor Roth strategy for high earners who want to maximize tax-free retirement savings beyond the standard Roth limits.
Fidelity is widely regarded as one of the best HSA providers as well, with no fees, no minimums, and full investment options, which matters for self-employed people on a high-deductible health plan who want to manage their HSA and retirement accounts at the same institution. FreshBooks
Fidelity and Vanguard both automatically sweep uninvested cash into money market funds yielding approximately 4 percent or more as of early 2026. This default cash yield is a meaningful detail for a freelancer who sometimes holds cash in the account between contributions, since that money earns a real return at Fidelity without any manual action required. Stephsbooks
The trade-off worth knowing: Fidelity’s zero-expense-ratio index funds like FZROX are genuinely low-cost, but they are proprietary mutual funds that only exist inside Fidelity accounts. If you ever want to move to Schwab, Vanguard, or another custodian, you will face a taxable sale of FZROX, which can trigger capital gains taxes in taxable accounts. For investors who value flexibility and portability, Vanguard’s VTI ETF at 0.03 percent expense ratio trades at any brokerage and transfers in-kind. In a Roth IRA or retirement account where sales are tax-free, this portability concern is largely irrelevant. FreshBooks
Charles Schwab: Best if You Want Integrated Banking and 24/7 Support
Charles Schwab earns the highest score for customer support, offering 24/7 phone and chat support, a large library of educational material, and multiple platforms including thinkorswim for more advanced users. Allied Tax Advisors
Schwab’s Solo 401k is solid, supports both traditional and Roth contributions, and charges zero commissions on stocks and ETFs. Schwab’s collection of no-transaction-fee mutual funds is more than double Fidelity’s, which matters for investors who want to access a wider range of third-party funds without paying additional trading costs.

Where Schwab genuinely wins for certain self-employed people is its integrated banking setup. Schwab wins if you want full banking services, including checking, savings, and mortgage, integrated directly with your brokerage. For a freelancer who wants one institution handling their investing, retirement accounts, and daily banking rather than maintaining separate relationships, Schwab’s combined offering is more complete than Fidelity’s. Wealthvieu
One detail worth knowing before moving money in: Schwab defaults to a low-yield bank sweep of approximately 0.45 percent. You must manually move cash to a money market fund like SWVXX to get a competitive rate. This is a meaningful difference from Fidelity’s automatic sweep, and it matters most for freelancers who hold larger cash balances between contributions. Stephsbooks
E*TRADE: Best Solo 401k for Loan Access and Roth Flexibility
E*TRADE deserves more attention in self-employed conversations than it typically gets, specifically because of its Solo 401k features. The plan supports both traditional and Roth contributions, allows loans, accepts rollovers of any kind, has no setup or annual fees, and charges zero commissions on stock and ETF trades inside the plan.
E*TRADE’s Solo 401k is particularly well-regarded for its combination of Roth deferral capability, loan provisions, and broad rollover acceptance, all at no cost, making it a strong choice for owner-only businesses who want full-featured retirement account access without plan administration fees. The loan provision, which allows borrowing up to $50,000 or 50 percent of the vested balance, is a feature some freelancers value as a financial safety net even if they never actually use it.

Vanguard: Best for Long-Term Index Fund Purists
Vanguard’s story in the self-employed account space has a recent development worth noting. Vanguard sold its self-employed business accounts, including the Solo 401k, to Ascensus. The branding is now Ascensus featuring Vanguard Investments. Ascensus offers traditional and Roth options and recently started allowing rollovers of existing IRAs into the Solo 401k plan, but still does not allow loans from the plan, and only allows participants to invest in Vanguard mutual funds, not even Vanguard ETFs. ExpertHelp Blog
That restriction to Vanguard mutual funds only is a meaningful limitation for freelancers who want a broader investment menu, and the absence of loan provisions further narrows the use case. Vanguard’s ideal customer in the retirement account context is a committed, long-term index fund investor who specifically wants direct access to funds like VTSAX, does not need a loan option, and values the firm’s client-owned structure above other features.
For a SEP-IRA specifically, Vanguard remains a perfectly functional choice with the low-cost fund selection that made the firm famous. The Solo 401k constraints are more significant than the SEP-IRA experience, which is simpler and less feature-dependent.
Comparing the Key Features Side by Side
| Brokerage | Solo 401k Roth Option | Solo 401k Loans | Default Cash Yield | Zero-Commission Trades | SEP-IRA Available |
|---|---|---|---|---|---|
| Fidelity | Yes | Yes | ~4%+ (auto sweep) | Yes | Yes |
| Schwab | Yes | Yes (confirm current terms) | ~0.45% (manual move needed) | Yes | Yes |
| E*TRADE | Yes | Yes | Low (check current terms) | Yes | Yes |
| Vanguard/Ascensus | Yes | No | Varies | Yes | Yes |
The Investment Strategy Inside the Account
Opening the right account at the right brokerage is only the first decision. What the money is invested in inside that account matters at least as much over a long time horizon.
For most self-employed people who are not active traders and are investing for decades-away retirement, a simple two or three fund portfolio of broad market index funds covers the bases without requiring ongoing management. A total US stock market index fund, a total international stock market index fund, and optionally a bond index fund in proportions that match your risk tolerance and time horizon is the core of what most evidence-based financial planners recommend for long-term retirement investing.
All four platforms covered here offer low-cost index funds that serve this purpose well. Fidelity’s zero-expense-ratio funds, Schwab’s own index ETFs, Vanguard’s flagship funds through Ascensus, and E*TRADE’s access to the full ETF market all provide the building blocks. The specific fund expense ratio differences between these platforms are genuinely small enough that the brokerage’s account features, customer service, and overall experience will affect your outcome more over a 30-year period than a 0.03 versus 0.00 percent expense ratio difference.
Taxable Brokerage Accounts for Investing Beyond Retirement Limits
Once you have maximized your Solo 401k or SEP-IRA contributions for the year, a taxable brokerage account lets you continue investing without the annual contribution caps that apply to retirement accounts. The tax treatment is different since growth is taxable in the year it is realized, but the long-term capital gains rate that applies to investments held more than a year is meaningfully lower than ordinary income tax rates for most self-employed people.
All four platforms offer full-featured taxable accounts with the same zero-commission trading and fund access as their retirement accounts. The Fidelity Cash Management Account in particular functions like a high-yield checking account integrated with a brokerage, which some freelancers find useful as a combined banking and investing solution without maintaining separate institutions for each purpose.
Frequently Asked Questions
Can I open a Solo 401k at any brokerage or only at the ones listed here?
The major retail brokerages listed here offer prototype Solo 401k plans, meaning the plan document is pre-approved by the IRS and the setup process is straightforward. There are also third-party plan document providers like MySolo401k that offer more customized plans with features like Mega Backdoor Roth, which can then be held at a brokerage of your choice as a non-prototype account. This setup offers more flexibility but involves more administrative responsibility.
Does it matter which brokerage I use for a SEP-IRA?
Less so than for a Solo 401k, since the SEP-IRA is a simpler account type with fewer structural variations between providers. The investment selection, fee structure, and customer service experience are the main differentiators. Any of the four platforms here supports a perfectly functional SEP-IRA, and the choice is mostly a matter of which brokerage you already have a relationship with or find easiest to work with.
Can I hold my Solo 401k and my taxable brokerage account at the same institution?
Yes, and most freelancers find it simpler to do so. Having retirement accounts, taxable accounts, and optionally a cash management account at one institution means one login, one set of statements, and one customer service relationship to manage. The only reason to split accounts across institutions is if specific features at different brokerages serve genuinely different needs that a single institution cannot match.
What happens to my brokerage account if the firm goes under?
SIPC protection covers brokerage accounts up to $500,000 in securities per account, including up to $250,000 in cash, in the event a brokerage firm fails. This protection applies to Fidelity, Schwab, E*TRADE, and Vanguard/Ascensus. SIPC does not protect against investment losses from market declines, only against the loss of securities due to a firm’s failure.
Final Thoughts
For most investors in 2026, the choice comes down to Fidelity and Schwab for slightly different reasons. Fidelity edges ahead for most people with its combination of zero-expense-ratio funds, automatic high-yield cash sweep, Solo 401k with Roth support, and a best-in-class mobile app. Schwab is the better choice if you want integrated banking alongside your investment and retirement accounts. E*TRADE earns a specific recommendation for freelancers who want the most complete Solo 401k feature set, particularly loan access and Roth flexibility, at no additional cost. Vanguard’s Solo 401k is more restricted than it used to be following the Ascensus transition, making it a stronger fit for SEP-IRA holders than for Solo 401k users in its current form. Wealthvieu
