As a freelancer with no employer plan, which solo 401(k) provider offers the easiest setup and lowest fees for index-fund investing?
Data as of Sep 24, 2026 · Based on 323 AI responses from ChatGPT Search and Google AI Mode · See how Parse measures this
For most freelancers who want the simplest, lowest-cost Solo 401(k) for index-fund investing, choose Fidelity or Charles Schwab — both offer $0 setup, no annual maintenance, and commission-free ETFs. Pick Schwab if you prioritize customer/service tools; choose E*TRADE only if you need a plan that allows loans.
Best if you want a no-fee Solo 401(k with strong customer service and trading tools; Schwab repeatedly appears as a top pick for $0 setup, $0 maintenance, and commission-free ETF access.
Good choice only if you need the ability to borrow from your Solo 401(k) or want Roth options; E*TRADE is cited for loan flexibility but is not singled out as the lowest-fee overall option.
For a freelancer with no employees other than possibly a spouse, Fidelity is probably the simplest low-cost choice for a solo 401(k) if your main goal is hands-off index-fund investing.

Index-fund investing
Notable consideration
Fidelity
$0
Excellent; includes 0%-expense-ratio Fidelity ZERO funds
Individual 401(k) administration is less compelling for a new solo plan
Fidelity explicitly says its Self-Employed 401(k) has no account fees or minimums, and its application can be completed online. It supports both traditional and Roth contributions.
For the investments themselves, Fidelity offers zero-expense-ratio index funds, including its ZERO Total Market and ZERO International funds. Its conventional index funds are also extremely inexpensive.
My practical recommendation
I'd choose Fidelity if you want:
$0 plan/account fees
Easy online setup
Traditional and Roth solo 401(k) contributions
Broad index-fund choices
The ability to simply buy and hold a low-cost portfolio
For example, you could use a simple U.S. total-market + international + bond-index allocation rather than trying to pick individual stocks.
One important wrinkle: if you think you'll want 401(k) participant loans or advanced features such as voluntary after-tax contributions/mega-backdoor Roth, the answer changes; E*TRADE or a custom solo-401(k) provider may be worth considering.
Also, for 2026, the employee contribution limit is $24,500, with a separate employer contribution component; the overall limit is generally $72,000 before applicable catch-up contributions.
If you tell me your approximate freelance net income, age, and whether you're a sole proprietor/LLC/S-corp, I can show you which provider and contribution strategy would minimize costs and maximize what you can put in for 2026.
zero setup fees, zero annual maintenance fees
$0 commissions
Fidelity
Charles Schwab
A breakdown of the best options shows how they compare for a solo investor:
Charles Schwab stands out as an exceptional choice for low-fee index investing. It charges $0 setup fees, $0 annual maintenance fees , and $0 online commissions for stocks and ETFs, alongside access to thousands of no-load, no-transaction-fee mutual funds. It features robust customer support, though like most free institutional brokerages, it doesn't support 401(k) participant loans. You can check details and start the process on the Charles Schwab Individual 401(k) page.
Fidelity Investments is frequently rated as an overall top pick for self-employed retirement accounts. It features no setup or annual fees and $0 commission on online US stock and ETF trades. Fidelity also allows direct electronic deposits and mobile check deposits to fund the account easily. Note that while they support Roth contributions, standard features like 401(k) loans are omitted. You can review their offerings directly via Fidelity's Small Business Retirement Plans.
E*TRADE is a strong alternative if you specifically want the flexibility of 401(k) loans (which neither Schwab nor Fidelity's basic plans support). ETRADE charges no setup fees and no annual account fees , with $0 trades for online ETFs and stocks. Their platform is feature-rich, though paperwork setup is slightly more traditional. Learn more through the ETRADE Individual 401(k) portal.
(Note: If you previously considered Vanguard , be aware that they exited the individual/Solo 401k market and transferred their client base to Ascensus, making them less relevant for a direct, native setup.)
To help narrow down which of these fits your exact freelance setup, tell me:
Do you anticipate needing a participant loan feature down the road?
Do you prefer investing via mutual funds (like FXAIX or SWPPX) or ETFs (like VTI or IVV)?

Vanguard is no longer my first choice for a new solo 401(k)
Fidelity explicitly says its Self-Employed 401(k) has no account fees or minimum to open, and it supports both traditional and Roth contributions. FidelityFidelity Its index-fund lineup is particularly inexpensive: for example, FZROX and FZILX have 0% expense ratios, while FXAIX and FSKAX are currently 0.015%.
E*TRADE also offers a traditional/Roth Individual 401(k), with $0 online commissions on U.S.-listed stocks, ETFs and mutual funds. E*TRADE Schwab likewise says there are no opening or maintenance fees, though fund expenses and other brokerage charges can apply.
My practical takeaway
If your goal is simply "open it, contribute, and buy broad-market index funds for decades", I'd start with Fidelity. The combination of $0 plan fees, Roth + traditional contributions, and extremely inexpensive index funds makes the cost structure hard to beat.
One important caveat: the cheapest/basic solo 401(k) isn't necessarily the right plan if you want special features such as participant loans, voluntary after-tax contributions/mega-backdoor Roth, or unusually sophisticated profit-sharing provisions. In that situation, a custom plan can be more appropriate.
If you tell me whether you're a sole proprietor, single-member LLC, or S-corp, I can also show you the 2026 contribution calculation and a simple 2–3 fund portfolio for the solo 401(k).
For a freelancer doing straightforward index-fund investing (like buying broad-market ETFs or mutual funds), the major mainstream retail brokerages offer the absolute lowest fees ($0 setup, $0 annual maintenance, and $0 trade commissions).
However, "easiest setup" and feature sets vary significantly among them. Fidelity and E*TRADE stand out as the top choices depending on your specific needs.
Top Brokerage Options for Low Fees & Index Funds
Fidelity Investments
Setup & Maintenance Fees: $0
Trading Commissions: $0 for online US stocks and ETFs. Access to ultra-low-cost index funds like the Fidelity 500 Index Fund (FXAIX) (expense ratio of 0.015%).
The Good: Incredibly cheap, allows electronic ACH/EFT direct deposits and mobile check deposits, and features broad investment choices. It now supports Roth contributions.
The Catch: Fidelity’s prototype Solo 401(k) does not allow 401(k) loans . If you ever want the option to borrow against your account, look elsewhere.
E*TRADE
Setup & Maintenance Fees: $0
Trading Commissions: $0 for online US stocks and ETFs.
The Good: Excellent range of account features. Unlike Fidelity, E*TRADE allows 401(k) loans , giving you liquidity if you ever need it. They also support both Traditional and Roth solo 401(k) options.
The Catch: Setting up the paperwork requires filling out and mailing/uploading their specific prototype plan documents, which is slightly more cumbersome than a standard retail account opening, though still free of third-party adoption costs.
Charles Schwab
Setup & Maintenance Fees: $0
Trading Commissions: $0 for online trades, with broad access to low-fee Schwab index funds and ETFs.
The Good: Completely free baseline cost and great customer service.
The Catch: Schwab's individual 401(k) plan traditionally lacks Roth contribution capabilities and loans, and electronically funding or linking external accounts can be less streamlined than Fidelity.
Vanguard
Note on status: Vanguard historically offered a basic solo 401(k), but they have phased out and discontinued new Solo 401(k) applications for individual investors, routing small business tools elsewhere.
Which one should you pick?
Go with Fidelity Investments if you want the absolute easiest digital experience, zero fees, top-tier zero-to-low expense ratio index funds (like FXAIX), and you are 100% sure you will never need a plan loan.
Go with E*TRADE if you want zero platform/maintenance fees combined with the safety net of permitting 401(k) loans.
To help narrow this down:
Do you anticipate ever needing a 401(k) loan feature for emergency liquidity?
Do you prefer Roth (after-tax) or Traditional (pre-tax) contributions for your business income?
For index-fund investing as a freelancer, you want a standard/free prototype Solo 401(k) from a major brokerage. You do not need a costly custom "self-directed" LLC-based Solo 401(k) (which charges hundreds in setup and annual admin fees) unless you plan to buy alternative assets like real estate or crypto.
The top major brokerages offer $0 setup fees, $0 annual maintenance fees, and $0 commission on online stock/ETF trades. However, they differ slightly in features and ease of use:
Fidelity Investments : Widely considered the best overall for a free Solo 401(k). It features $0 setup and maintenance fees, $0 stock/ETF commissions, and lets you invest in ultra-low-cost index funds like the Fidelity 500 Index Fund (FXAIX) (expense ratio of 0.015%). Fidelity also supports Roth contributions and EFT/mobile check deposits, though standard features like 401(k) loans are not supported on their basic platform.
Charles Schwab : Excellent for low fees and a straightforward index-fund approach. Schwab charges $0 in maintenance or setup fees and gives you access to top-tier Schwab and third-party index mutual funds and ETFs with zero transaction commissions. It's a great fit if you prefer a traditional, no-fuss brokerage interface.
E*TRADE : Noted for having the best overall account features among free providers. Unlike Fidelity or Vanguard, E*TRADE's Solo 401(k) actually allows 401(k) loans , which can be an appealing safety net for freelancers. They charge $0 account fees and offer thousands of commission-free ETFs and mutual funds.
Vanguard : Known as the pioneer of index funds, but less ideal for a Solo 401(k). Vanguard charges a $20 annual fee per fund held in the account (unless you maintain a total of $50,000+ across Vanguard assets to get it waived), making it slightly less optimized for small or starting balances compared to Fidelity or Schwab.
To help narrow down the best home for your money, tell me:
Do you need the ability to take a 401(k) loan in an emergency?
Are you planning to contribute heavily to Roth or Traditional (pre-tax)?

Generally not worth choosing for a new solo 401(k)
Fidelity explicitly says its Self-Employed 401(k) has no plan account fees, and its 2026 plan allows up to $72,000 in combined employee/employer contributions before applicable catch-ups. Fidelity Fidelity also offers $0 online ETF commissions and several index mutual funds with 0% expense ratios.
Why I'd choose Fidelity: you can keep the entire setup at one brokerage without paying a third-party administrator just to buy ordinary index funds. Schwab is similarly inexpensive, but Fidelity has an especially compelling lineup of ultra-low-cost index funds. Schwab's online U.S.-listed ETF trades are also $0.
One important distinction: $0 provider fees ≠ $0 investment expenses. Look at the expense ratio of whatever index fund you actually select.
For a straightforward portfolio, you could use a U.S. total-market index fund + international index fund + bond index fund, with the percentages based on your risk tolerance.
Bottom line: Fidelity is my default recommendation for a solo freelancer in 2026. If you tell me whether you're a sole proprietor, single-member LLC, or S-corp and roughly how much you expect to contribute annually, I can also compare the tax advantages and show you exactly how I'd structure the solo 401(k).
For index-fund investing as a freelancer, you do not need (and should avoid) expensive "self-directed" boutique Solo 401(k) providers that charge hundreds in setup and annual maintenance fees. Instead, you want a free, prototype-plan brokerage.
The three major brokerages offering $0 setup and $0 annual maintenance fees for standard index-fund investing are Fidelity, Charles Schwab , and E*TRADE.
Top 3 Free Solo 401(k) Providers Compared
Fidelity Investments (Best Overall)
Setup & Maintenance Fees: $0
Trading/Fund Fees: $0 online stock/ETF trades; access to industry-leading low-cost index funds like FXAIX (S&P 500 index at a tiny 0.015% expense ratio).
The Catch: Fidelity’s Solo 401(k) does not allow 401(k) loans . It does support Roth contributions, but lacks in-service distributions.
Setup Ease: Very straightforward paperwork, and they now support electronic fund transfers (EFT) and mobile check deposits.
Charles Schwab (Best for Low Fees & Mutual Funds)
Setup & Maintenance Fees: $0
Trading/Fund Fees: $0 online stock/ETF commissions, plus access to thousands of no-transaction-fee mutual funds.
The Catch: Like Fidelity, Schwab does not allow 401(k) loans on its individual 401(k) plan.
Setup Ease: Requires paper application submission (mailed or faxed), which makes the initial setup slightly clunkier than a fully digital signup, but customer service is excellent.
E*TRADE (Best for Account Features & Loans)
Setup & Maintenance Fees: $0
Trading/Fund Fees: $0 online trades for stocks and ETFs.
The Catch: The interface is geared a bit more toward active traders, but for pure index investing, it works seamlessly.
The Big Advantage: Unlike Fidelity and Schwab, E*TRADE allows 401(k) loans . If having the option to borrow against your solo 401(k) in an emergency is important to you, E*TRADE wins.
Setup Ease: Relatively easy application process, though it requires mailing/faxing signed adoption agreements.
Which one should you pick?
Choose Fidelity if you want the absolute easiest digital experience, want to buy ultra-low-cost proprietary index funds (like FXAIX), and do not care about taking loans from your account.
Choose E*TRADE if you want the flexibility of 401(k) loans while keeping all setup and maintenance costs at $0.
Avoid Vanguard for a Solo 401(k); while their index funds are fantastic, Vanguard outsources/sells their individual 401(k) administration and historically charges per-fund service fees unless you maintain massive account balances.
To help narrow down the best fit, tell me:
Do you ever anticipate needing a 401(k) loan?
Do you prefer Fidelity's digital-first platform or E*TRADE's loan flexibility?
If your priorities are easy setup + very low fees + straightforward index-fund investing, my pick is Fidelity.

1. Fidelity — best overall for a solo freelancer.
Fidelity explicitly offers a Self-Employed 401(k) for owner-only businesses, with no fees to open or maintain most plans. Its brokerage platform also gives you $0 online ETF trades and a selection of 0%-expense-ratio Fidelity ZERO index funds.
That combination is hard to beat: you can keep the 401(k) at Fidelity and build a simple portfolio using broad index funds without paying an account-management fee.
2. Schwab — probably the closest competitor.
Schwab's Individual 401(k) has $0 opening and maintenance fees and a $0 minimum. Its index funds are exceptionally cheap—for example, SWTSX (total U.S. stock market) is 0.03% and SWPPX (S&P 500) is 0.02%.
3. E*TRADE — excellent if you want flexibility.
E*TRADE's Individual 401(k) supports both traditional and Roth contributions and allows mutual funds, ETFs, stocks and more. It also currently offers several proprietary index funds with 0% expense ratios.
The important distinction
Don't focus only on the provider's account fee. For a long-term index investor, there are really three costs:
Solo 401(k) administrative/account fees
Trading/transaction fees
Fund expense ratios
Fidelity and Schwab are particularly compelling because you can get essentially $0 plan/account fees + extremely inexpensive index funds. Fidelity's ZERO funds can even eliminate the fund expense ratio altogether.
What I'd choose
For most freelancers: Fidelity Self-Employed 401(k).
A simple portfolio could be something like:
Total U.S. stock market index
Total international stock index
U.S. bond index, if appropriate for your risk tolerance
You don't need an advisor or a complicated managed plan just to accomplish this.
One caveat: if you're a sole proprietor, single-member LLC, S-corp, or C-corp, the contribution calculation and paperwork can differ, and the solo 401(k) has more administrative requirements than an IRA. Fidelity notes that the plan is intended for businesses with no employees other than a spouse.
Bottom line:Fidelity wins for the easiest combination of setup, $0 basic fees, and low-cost index investing. Schwab is an extremely close second.
If you tell me roughly your annual freelance profit ($50k, $100k, $200k, etc.) and whether you're a sole proprietor or S-corp, I can also compare Fidelity vs. Schwab vs. E*TRADE on your actual contribution limits and tax savings for 2026.
For index-fund investing with zero maintenance fees and simple online setup, Fidelity and Charles Schwab are the best overall choices for a Solo 401(k).
An index fund is a mutual fund or exchange-traded fund (ETF) designed to copy the performance of a broad market index like the S&P 500. An expense ratio is the annual fee a fund charges you as a percentage of your investment.
Top Solo 401(k) Providers
Fidelity Investments : Rated best overall by Investopedia . It charges $0 setup fees and $0 annual maintenance fees . You get $0 commission on online US stocks and ETFs, and ultra-low-cost index funds like the Fidelity 500 Index Fund (FXAIX), which has a near-zero expense ratio of 0.015% [0.015% fee]. Setup is fully digital and straightforward.
Charles Schwab : Excellent for low-fee trading with $0 setup fees and $0 annual maintenance fees . Schwab offers commission-free trading on stocks and ETFs alongside a huge selection of low-cost Schwab index funds. Its platform and mobile tools make execution very smooth for self-employed individuals.
E*TRADE : Features a robust Solo 401(k) with $0 setup or annual maintenance fees and allows 401(k) loans. However, some users report that the initial paperwork and application process for an individual 401(k) can feel slightly more clunky compared to Fidelity.
Vanguard : Known as a pioneer of index funds, but less ideal for a Solo 401(k) because they charge a $20 annual fee per fund held, unless you keep a total balance over $50,000 across your Vanguard accounts. They also transferred parts of their individual plan operations to Ascensus, making their direct setup less seamless.
If you'd like, let me know:
Do you plan to make Roth (after-tax) or Traditional (pre-tax) contributions?
Do you ever need the option to take a 401(k) loan?
I can help you pick the exact platform for your needs.
For a freelancer who wants a solo 401(k) primarily for low-cost index-fund investing, I’d pick Fidelity for the best combination of easy setup, $0 plan fees, and inexpensive index funds.

Why Fidelity wins: Fidelity's Self-Employed 401(k) currently has no account fees, and its brokerage platform gives you $0 online stock/ETF commissions.
For index investing specifically, Fidelity is unusually attractive. For example, its Fidelity 500 Index Fund (FXAIX) and Fidelity Total Market Index Fund (FSKAX) each have a 0.015% expense ratio, with no investment minimum. Fidelity Fidelity also offers its ZERO index funds with 0% expense ratios, although I'd generally favor the established conventional index funds for a retirement portfolio because they're more broadly portable/standardized.
E*TRADE is a very close second. Its Individual 401(k) supports both traditional and Roth contributions and lets you invest in mutual funds, ETFs, stocks, and more.
The big differentiator is that E*TRADE's standard solo 401(k) can be preferable if participant loans are important to you. Otherwise, Fidelity's combination of setup simplicity and index-fund choices makes it my default.
If I were a one-person freelancer starting from scratch today: Fidelity.
You get:
$0 setup/ongoing account fees
Traditional and Roth 401(k) contributions
Very inexpensive broad-market index funds
$0 online ETF/stock trades
A straightforward mainstream brokerage to keep for decades
One caveat: the cheapest provider isn't necessarily the best if you want advanced features such as mega-backdoor Roth contributions, unusual profit-sharing provisions, or specialized plan documents. In that case, a third-party/custom solo-401(k) provider can make sense despite higher fees.
Also, don't confuse the $72,000 2026 total contribution limit with the employee-deferral limit; the calculation for a self-employed person depends on your business structure and earned income. Fidelity confirms the $72,000 overall limit for 2026.
If you tell me (1) sole proprietor vs. S-corp, (2) approximate net self-employment income, and (3) your age, I can compare Fidelity vs. E*TRADE vs. Schwab and show exactly how much you could contribute and which funds I'd use.
When I'd choose E*TRADE instead
E*TRADE is a very close second. Its Individual 401(k) supports both traditional and Roth contributions and lets you invest in mutual funds, ETFs, stocks, and more.
