Fidelity Investments and Charles Schwab run nearly neck and neck as recommendations for low-cost IRAs, rollovers, and small business plans. Charles Schwab becomes the usual answer when near-retirees ask for planning tools to model Roth conversions and required minimum distributions.
Since July, E*TRADEfalling is mentioned noticeably less across retirement questions.

🥇 My pick: Fidelity
Fidelity Investments is particularly attractive for a solo business owner because Fidelity says its SEP IRA has no account fees or minimum to open, can be opened online in minutes, and supports online employer contributions. It also handles the administrative simplicity of a SEP—there are generally no annual IRS plan filings.
Investment choices are excellent: you can buy stocks, bonds, ETFs and mutual funds, including very low-cost index funds. Fidelity also has zero-expense-ratio index funds, which is a notable advantage if you're building a simple, inexpensive portfolio.
If you don't want to manage investments yourself, Fidelity Go is another option, although its advisory fee becomes 0.35% annually once the balance reaches $25,000.
🥈 Schwab: arguably the best alternative
Charles Schwab also charges $0 to open or maintain a SEP IRA, with a $0 minimum. It offers $0 online commissions for listed stocks and ETFs and a very broad selection of commission-free ETFs and no-transaction-fee mutual funds.
One advantage Schwab has over Fidelity is physical branch access and 24/7 customer service, which can be useful if you'd rather have someone walk you through something.
What I'd actually invest in
If your goal is simple + diversified + very low cost, you don't need a complicated portfolio. At Fidelity or Schwab, I'd generally consider something along these lines:
One target-date index fund — easiest, essentially hands-off.
Or a total U.S. stock-market index fund + international index fund + bond index fund.
If you're comfortable with volatility and have a long horizon, a simple broad-market index approach can keep expenses extremely low.
The important distinction is that the brokerage's $0 account fee isn't the same thing as the investment's expense ratio. You want both to be low.
One important SEP-IRA consideration
If you're self-employed with no employees other than possibly a spouse, don't automatically assume a SEP IRA is your best choice. A solo/self-employed 401(k) can sometimes allow substantially more favorable contribution flexibility because you can contribute in both an employee and employer capacity. Fidelity, for example, specifically positions its self-employed 401(k) for owner-only businesses.
Bottom line: Fidelity SEP IRA = my default recommendation for easiest setup + $0 account costs + excellent low-cost investment choices. Schwab is essentially tied if you value customer service/branches more. Vanguard is attractive if you're already committed to Vanguard's funds, but I'd choose Fidelity for the overall small-business experience.
If you tell me (1) whether you're a sole proprietor/LLC/S-corp, (2) whether you have employees, and (3) roughly how much you expect to contribute, I can also compare SEP IRA vs. Solo 401(k) for your situation—which may be the more important decision.
Ease of Setup: Offers smooth digital workflows and strong customer phone support to walk you through employer-eligibility forms (like IRS Form 5305-SEP).
Investment Options: Zero-expense-ratio index funds (like FZROX and FZILX) and low-cost broad market ETFs ($0 commission).
If you're choosing a brokerage for a SEP IRA, I’d focus less on the brokerage’s headline trading commissions and more on how easy the SEP is to administer and whether it fits your business situation.
What to compare
SEP-specific fees
Account-opening fee
Annual/maintenance fee
Per-employee fees
Investment or advisory fees
Transfer/closure fees
For example, Fidelity currently advertises no account fees or minimums for its SEP IRA, while Schwab likewise lists $0 opening/maintenance fees and a $0 minimum.
Investment choices and costs
Look for inexpensive:
Broad-market index ETFs
Mutual funds
Bonds/CDs
Target-date funds, if you want something hands-off
Don't just look at "commission-free." Fund expense ratios can matter much more over decades.
SEP administration
This is particularly important if you have employees. Ask:
Who provides the SEP paperwork?
How do you establish the plan?
How do employees open their accounts?
How are contributions made?
Does the brokerage provide reminders/help with contribution administration?
Fidelity, for example, says employers can make contributions online and that each eligible employee needs their own SEP IRA.
Employee requirements
A SEP isn't simply a way for a business owner to put money away for themselves. Generally, contributions have to follow the SEP's rules for eligible employees. The employer contribution percentage generally has to be the same for eligible employees as for the owner.
Contribution flexibility
SEP IRAs are attractive for businesses with variable income because contributions can be flexible from year to year. For 2026, the SEP contribution limit is generally the lesser of 25% of compensation or $72,000; self-employed individuals have special rules for calculating the applicable compensation/contribution. SEP plans don't permit employee salary-deferral contributions.
Ease of use
If you're running a one-person business, this can be a surprisingly important consideration. Look for:
Easy online contributions
Simple account setup
Good mobile/desktop experience
Easy beneficiary changes
Good customer service
Clear tax documents
Tax/reporting support
Understand exactly what you are responsible for versus what the brokerage handles. Fidelity, for example, advertises its SEP IRA as requiring no IRS filings or reporting by the account holder, but you still have business/tax responsibilities associated with establishing and funding the plan.
The big question: SEP IRA vs. Solo 401(k)
If you're self-employed with no employees other than possibly a spouse, don't automatically assume a SEP IRA is the best choice.
A Solo 401(k) can allow you to contribute in both an employee and employer capacity, whereas a SEP IRA generally only accepts employer contributions. Fidelity explicitly distinguishes the two this way.
So if your goal is maximizing retirement contributions while you're self-employed, I'd compare these two before opening anything.
My practical shortlist
For a straightforward SEP IRA, I'd start by comparing:
Fidelity Investments — strong combination of $0 SEP account fees, broad investments, and online administration.
Charles Schwab — also $0 SEP opening/maintenance fees and $0 minimum, with a broad brokerage platform.
Vanguard — worth considering particularly if your priority is low-cost index investing, though I'd compare its current SEP administration experience and fees directly with Fidelity/Schwab.
If I were narrowing it down, I'd make a spreadsheet with just these columns: SEP fees, employee fees, investment expense ratios, investment selection, contribution process, customer service, and Solo 401(k) availability.
If you tell me (1) whether you're a sole proprietor/LLC/S-corp, (2) roughly how much you expect to contribute, and (3) whether you have employees, I can compare Fidelity vs. Schwab vs. Vanguard vs. a Solo 401(k) and tell you which is likely the best fit.
When choosing a brokerage to open a SEP IRA, you should look for zero account fees, a wide selection of low-cost investment options, and a streamlined digital setup process.
Low or Zero Fees: Look for brokerages that charge $0 account opening fees, $0 annual maintenance fees , and $0 commission fees on standard stock, exchange-traded fund (ETF), and online trades. Some platforms still charge annual fees for specific mutual funds or multi-person plans, so check the fine print if you have employees.[](https://www.finder.com/retirement/best-sep-ira)
Investment Selection: Ensure the brokerage offers a robust variety of asset classes, including stocks, bonds, ETFs, and mutual funds . If you prefer a hands-off approach, verify whether they offer automated investing or advisor services.
Employee Management (if applicable): If you have a small business with staff, choose a provider that supports multi-person SEP IRAs with easy digital onboarding, tracking, and streamlined employer contribution distribution.[](https://www.finder.com/retirement/best-sep-ira)
Ease of Use and Platform Tools: Look for a clean, intuitive interface, reliable mobile check deposits, electronic fund transfers (EFT), and robust retirement planning calculators or customer support.[](https://www.fidelity.com/retirement-ira/small-business/sep-ira)
Research and Educational Resources: Access to clear guidance on contribution limits (such as the limits for 2026 capped at $72,000 or 25% of compensation) and tax resources will make managing your annual deposits much easier.[](https://www.fidelity.com/retirement-ira/small-business/sep-ira)
If you'd like, let me know:
Whether you are self-employed with no employees or have a small team
What types of investments you plan to buy (ETFs, mutual funds, individual stocks)
I can recommend specific brokerages that fit your exact business setup.
When choosing a custodian or financial institution to hold your SEP IRA, you want to prioritize structures that minimize drag on your compounding returns while giving you the investment freedom you need. Because SEP IRAs are designed for self-employed individuals and small business owners, the administrative burden should stay low.
Trading and Commission Fees: Prioritize $0 commissions for online trades of stocks, exchange-traded funds (ETFs), and standard options. If you plan on investing heavily in mutual funds, check if the provider charges transaction fees or loads for the specific funds you want, or if they offer a robust list of no-transaction-fee (NTF) funds.[](https://www.merrilledge.com/small-business/sep-ira)[[2]()]()
When choosing where to open your SEP IRA, I’d focus on total costs, investment choices, ease of administration, and whether the provider fits your business as it grows. The right choice depends on whether you’re self-employed with no employees or running a business that contributes to retirement accounts for employees.
A SEP IRA is a retirement plan funded by employer contributions, including contributions you make for yourself if you're self-employed. The financial institution you select holds the accounts and provides the investment options.
The 7 key features to compare
1. Total fees and expenses
This is one of the most important comparisons because fees reduce your investment returns over time.
Annual account or custodial fees
Trading commissions and transaction fees
Mutual fund and ETF expense ratios
Managed-account or financial-advisor fees
Account transfer, closure, or termination fees
What to look for: No recurring account fee, low-cost index funds, and transparent pricing. Check for minimum balances or conditions that waive fees.
2. Investment selection
Compare whether you can invest in the assets you actually want to hold.
For a freelancer with no employer-sponsored retirement plan, I’d prioritize a solo 401(k) with no recurring account fees, no trading commissions for index funds, and a straightforward online application.
The best provider depends on whether you want the easiest setup, the lowest long-term cost, or the flexibility to invest in a broad range of low-cost index funds. Also, a solo 401(k) is generally available if you have self-employment income and no eligible employees other than a spouse.
My top pick: Fidelity Investments
(Best overall)
Fidelity Self-Employed 401(k)
$0
Account fees · No minimum account balance
Fidelity offers online setup, traditional and Roth contribution options, and access to stocks, ETFs, and mutual funds. Its standard plan doesn't offer participant loans.
Why I'd choose it: if you simply want to make regular contributions and invest in low-cost index funds without paying a plan-administration fee, Fidelity is a strong combination of simplicity, cost, and investment choice. It also offers some index mutual funds with a 0% expense ratio, although those aren't necessarily the best fit for every portfolio.
How the leading providers compare
These are the three mainstream providers I'd compare first for a basic, self-directed solo 401(k). The $0 figures refer to standard plan/account fees, not every possible investment or service cost.
1. Fidelity
$0 setup/account fees
Best for easy online opening and ultra-low-cost index mutual funds. Offers traditional and Roth contributions; no participant loans under its standard plan.
A great alternative if you prefer ETFs or Schwab mutual funds. Online stock and ETF trades are commission-free; fund expense ratios and some transaction fees may still apply.
Worth considering if you want a participant-loan feature alongside conventional index-fund investing. Verify the current plan documents and eligibility before opening.
Plan and trading fees: Fidelity, Schwab, and ETRADE offer basic solo 401(k) plans with $0 standard account fees. ETRADE also lists $0 online commissions for many stocks, ETFs, and mutual funds.
Fund expense ratios: These are the ongoing costs charged by the investments themselves. For example, a fund charging 0.03% costs about $3 per year for every $10,000 invested; a fund charging 0.10% costs about $10.
You don't need to pay an advisor or buy a managed portfolio to invest in index funds.
Three things to check before opening the account
Traditional versus Roth contributions. Traditional contributions may reduce taxable income today; Roth contributions are made after tax and may qualify for tax-free withdrawals later.
Special features. If you want participant loans or advanced after-tax contributions for a mega-backdoor Roth strategy, check the plan documents carefully. A basic, low-fee plan may not support these features.
Ongoing paperwork. The plan owner is responsible for administration and applicable tax filings. Generally, a one-participant plan must file Form 5500-EZ when combined plan assets exceed $250,000 at year-end, with an exception for the final plan year.
For 2026, the standard solo 401(k) contribution limit is $72,000 before eligible catch-up contributions, subject to compensation and other applicable rules.
My bottom line: Start by comparing Fidelity's Self-Employed 401(k) and Schwab's Individual 401(k). I'd lean toward Fidelity for a straightforward, low-cost index-fund portfolio, and choose E*TRADE instead if its participant-loan feature matters to you.
One important question before you commit: Do you operate as a sole proprietor/LLC, or do you pay yourself through an S corporation? That can affect contribution calculations and the setup details you should prioritize.
For a freelancer looking for zero annual fees, effortless setup, and $0 commission index-fund or ETF investing , the top major brokerages are Fidelity, Charles Schwab , and E*TRADE.
None of these three charge a setup fee or a yearly account maintenance fee for a standard prototype Solo 401(k). However, they differ slightly in features like Roth contributions and loan options.[](https://www.forusall.com/401k-blog/top-solo-401-k-providers)
(Note: Vanguard used to be a major player here, but they completely exited the individual 401(k) business, transferring those services to Ascensus.)
Choose Fidelity if you just want the absolute lowest-cost index fund options (like their zero fee funds) and don't care about borrowing against the account.
If your goal is “put as much as practical into a Solo 401(k), keep fees tiny, and invest automatically in broad index funds,” the setup can be very simple.
My preferred approach
For a freelancer with no employees other than a spouse:
Open a Solo 401(k) at a low-cost provider.
Make both types of contributions:
Employee deferral: up to $24,500 in 2026 (traditional/pre-tax or Roth, depending on the plan).
Employer contribution: generally up to 25% of compensation for an incorporated business; self-employed individuals have a special calculation based on net self-employment earnings.
The overall 2026 limit is $72,000, before applicable catch-up contributions.
Invest the contributions in broad-market index funds, rather than trying to pick stocks.
Automate contributions/investing where your cash flow permits, while keeping enough cash aside for taxes and business expenses.
Rebalance only occasionally—there's generally no need to trade frequently.
Where I'd look first
Fidelity is particularly compelling for a one-person operation. Its Self-Employed 401(k) currently advertises , and Fidelity offers very inexpensive index funds.
Setting up a Solo 401(k) is one of the highest-leverage moves you can make as a freelancer. To run it with maximum efficiency—meaning zero administrative fees, rock-bottom expense ratios, and minimum friction—you want to follow a clean, structured workflow.
The most efficient roadmap to fund your Solo 401(k) with low-cost index funds spans three key phases:
I am a freelancer opening a solo 401(k) and want to know how to put my money into inexpensive index funds.
Ease of Setup: Straightforward small-business center with clear digital document submission, though it can feel slightly more bureaucratic than Fidelity for small teams.
Investment Options: Massive selection of low-cost Schwab index funds/ETFs and a very broad list of no-transaction-fee mutual funds.
Vanguard (Best for Long-Term Buy-and-Hold Indexing)
Setup & Fees: $0 setup fee. Vanguard charges an annual account fee (often around $20–$25, which can sometimes be waived if you opt for electronic delivery or cross a certain asset threshold), though it's still relatively minimal.
Ease of Setup: Historically more traditional/paper-heavy or rigid in its small business verification flow compared to Fidelity.
Hidden/Transactional Fees: Watch out for "death by a thousand cuts" fees. Scrutinize the fee schedule for outgoing wire transfer fees, check-writing fees, paper statement fees (avoidable by going paperless), and account closing or transfer-out ("break-up") fees if you ever decide to move your money elsewhere.[](https://americanalternativeassets.com/blog/self-directed-ira-custodian-fee-comparison-dont-get-fleeced/)
Alternative Asset Custody Fees (If Applicable): If you are using a self-directed SEP IRA for alternative assets like real estate or private equity, flat annual fees are generally preferable to asset-valued tiered fees, which get aggressively expensive as your portfolio grows.[](https://www.iraresources.com/self-directed-ira/fees/comparison)
Features to Prioritize
Investment Selection: Ensure the platform gives you access to the asset classes you actually want to trade—whether that’s a broad universe of low-cost index funds, individual equities, or self-directed alternatives.
Contribution Flexibility and Ease: Because SEP IRA contribution limits scale with your net earnings or compensation (up to $72,000 for 2026), look for a custodian that makes annual contributions straightforward via electronic funds transfer (EFT), and provides clear year-end tax reporting without extra hassle.
User Interface and Administration: A clean, intuitive dashboard makes it easy to calculate and log contributions, view performance across multiple employee accounts (if you have a small business with eligible staff), and download tax forms quickly.
To help narrow down the right home for your account, you can explore major options like Fidelity Investments or Merrill Edge for standard low-cost self-directed public market investing.
To help narrow down the best provider, let me know:
What kind of assets do you plan to invest in (stocks/ETFs vs. real estate/alternative assets)?
Do you have employees you need to contribute for, or is it just for yourself?
If you're choosing a brokerage for a SEP IRA, I’d prioritize ongoing investment costs and flexibility over small differences in account fees. For a long-term retirement account, a 0.25%–0.50% annual fee can matter far more than a $20 account charge.
What I’d prioritize
Low-cost investment options — highest priority
Look for broad, low-cost index ETFs/mutual funds.
Pay attention to the expense ratio of the funds, not just the brokerage's advertised $0 commissions.
Ideally, you want plenty of diversified funds with expense ratios around 0.05%–0.20% or lower.
Fidelity, for example, currently offers several 0%-expense-ratio index mutual funds, although you should still compare the funds' investment characteristics rather than choosing solely on the headline fee.
$0 account/maintenance fees
This is increasingly standard. Fidelity and Schwab currently advertise $0 account fees, while Vanguard's comparison page notes a $20 annual account-service fee in some circumstances.
A $20 fee isn't necessarily a deal-breaker, particularly if it can be waived, but there's little reason to pay it if everything else is comparable.
Investment selection
Make sure you can buy the things you actually want:
Total U.S. stock-market index
International-stock index
Bond index
Treasury funds/individual Treasuries
Target-date funds, if desired
CDs or money-market funds, if useful
Fidelity, Schwab and Vanguard all offer broad brokerage investment choices, with $0 online stock/ETF commissions currently advertised.
Easy SEP contributions
This is more important than it sounds if you're self-employed. Check how easy it is to:
Make employer contributions
Schedule or initiate contributions
Track contributions by tax year
Handle contributions made after year-end but before your tax-return deadline
The IRS allows a SEP to be established as late as the business's tax-return due date, including extensions, and contributions generally must be made by that deadline to be deductible.
Good tax-documentation and administrative support
If you have employees, I'd put this considerably higher on the list. SEP contributions generally have to follow the plan's allocation rules, and contributions generally must be the same percentage of compensation for eligible participants.
Robo-advisor/advice fees — only if you'll use them
If you want someone/something to manage the portfolio, compare the advisory fee separately from fund expenses. For example, Fidelity Go currently charges 0% below $25,000 and 0.35% annually at $25,000+.

One important point: don't overemphasize trading commissions. If you're buying a few diversified ETFs and holding them for decades, the difference between $0 and a small trading commission is usually trivial. An ongoing 0.50% advisory fee or a 0.75% fund expense ratio is much more consequential.
For context, the IRS says the SEP contribution limit rises to $72,000 for 2026, subject to the applicable compensation percentage rules, so investment costs can become particularly meaningful if you're making large annual contributions.
My practical shortlist: I'd start by comparing Fidelity, Schwab, and Vanguard for a self-directed SEP IRA. All three are capable choices; I'd then pick based on the specific funds you intend to hold, total ongoing costs, and how easy the SEP administration is for your situation.
If you tell me roughly how much you expect to put into the SEP each year and whether you're self-employed with no employees or have employees, I can narrow this down to the best 2–3 choices and show the fee difference in dollars.
What to look for: A broad selection of diversified, low-cost funds. You generally don't need the widest selection possible; you need the right investments at a reasonable cost.
3. Setup and ongoing administration
Providers vary in how much help they offer with the SEP plan itself.
Assistance adopting the SEP plan document
Help opening and funding accounts
Support for accounts belonging to eligible employees
Contribution tracking and annual statements
Help with required notices and plan documentation
What to look for: A provider that clearly explains which administrative tasks it handles and which remain your responsibility. Opening an investment account alone may not complete the entire SEP setup.
4. Contribution flexibility
SEP IRAs allow you to vary employer contributions from year to year, including contributing nothing in a given year, subject to the plan's rules.
Easy one-time or recurring contributions
Straightforward bank transfers
Clear contribution deadlines
Tools for calculating contributions if you're self-employed
What to look for: A provider that makes it easy to contribute more in strong business years and less when cash flow is tight.
5. Customer support and financial guidance
Access to a human representative
Retirement-planning tools and calculators
Help with transfers, contributions, and tax forms
Optional investment advice
Clear disclosure of advisor compensation
What to look for: Responsive support and, if you need personalized advice, an advisor who explains their fees and fiduciary obligations.
6. Account portability and flexibility
Ability to transfer assets to another provider
Fees or restrictions on transferring investments in kind
Access to rollover options
Ability to keep your investments if you change providers
What to look for: Straightforward transfers and minimal exit fees. SEP IRA assets can generally be rolled over to other eligible retirement accounts, subject to applicable rules.
7. Employee support and future growth
If you have employees, or may hire them, this deserves special attention.
How eligible employees establish their own SEP IRAs
Whether the provider can support multiple participant accounts
Whether employees can choose their own investments
Whether your business needs a different plan document
Whether a 401(k) or another retirement plan may better fit your future needs
What to look for: A provider that can handle your current situation without creating unnecessary administrative work as your business changes. SEP contributions generally must follow the plan's allocation rules for eligible employees.
Which providers should you compare?
These three are reasonable starting points for a self-directed SEP IRA. Verify the current SEP-specific fees and account terms before opening an account; general IRA pricing isn't always identical to SEP IRA pricing.
Fidelity
A strong starting point if you want a broad investment selection, low-cost index funds, and flexible investing tools. Fidelity advertises $0 account fees and no minimum to open many retail IRAs.
Worth comparing if you value customer service, in-person branches, and investment research. Schwab advertises $0 opening and maintenance fees for its standard IRA offering.
Worth considering if your priority is long-term investing with diversified index funds. Pay particular attention to its current brokerage account fees, fund minimums, and any waivers that apply to you.
Use this when reviewing each provider's official SEP IRA page or fee schedule.
Before opening an account of
One important tax consideration: for 2026, total SEP contributions are generally limited to the lesser of 25% of eligible compensation or $72,000 per participant, subject to special calculation rules for self-employed individuals. Employee eligibility and contribution-allocation rules also matter if you run a business with staff.
Are you opening the SEP IRA just for your self-employment income, or do you have employees too?
That distinction will help determine whether to prioritize a low-cost brokerage account or a provider with more hands-on small-business plan administration.
When selecting a financial institution or custodian to open your SEP IRA, the core tax and contribution rules remain identical regardless of where you go . However, the platform experience, cost, and ease of administration can vary significantly.[](https://www.finder.com/retirement/best-sep-ira)
The key features to compare when evaluating providers include:
Fees and Commissions: Look out for account setup fees, annual maintenance fees, and trading commissions. Many major brokerages (like Fidelity Investments or Charles Schwab ) feature $0 online stock, ETF, and standard mutual fund trades with zero annual account fees, while other boutique or robo-advisor platforms may charge management or advisory fees.[](https://www.finder.com/retirement/best-sep-ira)
Investment Selection: Check what asset classes the platform allows you to trade. If you want a hands-on approach with individual stocks, international equities, options, or a broad choice of low-cost index funds and ETFs, a traditional brokerage is ideal. If you prefer a hands-off approach, a robo-advisor like Wealthfront might be preferable.[](https://www.finder.com/retirement/best-sep-ira)
Ease of Employee Administration: If you have employees (remember that a SEP IRA requires you to make proportional contributions for eligible employees), look at how easy the provider makes batch or direct employer funding. Some platforms offer better employer dashboards and customer service to handle multi-account contributions seamlessly.[](https://www.finder.com/retirement/best-sep-ira)
Account Minimums: Verify if there are minimum deposit requirements to open the account or to waive certain administrative or advisory fees.[](https://www.finder.com/retirement/best-sep-ira)
Research and Tools: Evaluate the quality of the platform's educational resources, retirement calculators, and analytical screening tools to help manage your portfolio over the long term.
If you'd like to narrow down your options, let me know:
Are you self-employed with no employees , or do you have employees you need to cover?
Do you prefer a hands-on investment style (stocks/ETFs) or a hands-off automated (robo-advisor) approach?
I can give you a more tailored recommendation based on your preferences.
Fidelity's conventional index funds such as FSKAX and FXAIX are already extraordinarily cheap, so I wouldn't choose a fund solely because it has a 0% expense ratio.
Schwab is another excellent option. Its broad-market SWTSX has a 0.03% expense ratio, while SCHB, its U.S. broad-market ETF, is also 0.03%. Schwab's international index options are similarly inexpensive.
A simple portfolio
If you're young and have a long retirement horizon, a straightforward example would be:
80% U.S. total stock market + 20% international stock market
For example, at Fidelity:
80% FSKAX
20% FZILX (or a conventional international index fund)
Or, if you want bonds for stability:
70% U.S. stocks / 20% international stocks / 10% U.S. bonds
The important point is that asset allocation matters much more than whether your index fund costs 0.00% versus 0.015%. Broad diversification and sticking with the plan are the big wins.
Traditional vs. Roth Solo 401(k)
This is an important decision.
Traditional/pre-tax contributions generally make more sense when you're in a relatively high tax bracket today and expect a lower marginal rate in retirement.
Roth contributions can be attractive when your current tax rate is relatively low and you expect your future tax rate to be higher. Roth contributions are after-tax, but qualified withdrawals can be tax-free. You can also split your employee contribution between traditional and Roth if your plan permits it.
One useful nuance: the employer/profit-sharing contribution is traditionally pre-tax, whereas the employee deferral can potentially be Roth.
One thing freelancers frequently get wrong
Don't simply calculate your employer contribution as 25% of your Schedule C profit.
For a sole proprietor, the calculation has to account for the deduction for one-half of self-employment tax and the contribution itself. That's why the actual maximum is somewhat less than a simple 25% × Schedule C profit calculation.
For example, if your freelance business has $100,000 of net profit, your maximum Solo 401(k) contribution isn't simply $24,500 + $25,000. The exact number depends on the self-employment-tax calculation.
Timing matters in 2026
If you're establishing the Solo 401(k) for the 2026 tax year, don't assume you can wait indefinitely to make the employee-election decision. The establishment and deferral rules vary depending on whether you're a sole proprietor, partnership, S-corp, etc. For subsequent years, contributions generally can be made by the business's tax-filing deadline, including extensions, but the rules for establishing the plan and making salary-deferral elections are more nuanced.
If you tell me (1) your approximate 2026 freelance profit, (2) whether you're a sole proprietor/LLC/S-corp, (3) your age, and (4) whether you have another employer 401(k), I can calculate your approximate maximum 2026 Solo 401(k) contribution and give you a specific low-cost index-fund allocation.
This is general educational information, not individualized tax advice; for an S-corp or unusually high income, it's worth having your CPA verify the contribution calculation.
Keep your portfolio design simple (the classic 1-to-3 fund approach) to reduce maintenance and rebalancing hassle. Opt for broad market ETFs or mutual funds.[](https://choosefi.com/investing/low-cost-index-fund)
Total U.S. Stock Market:
Fidelity: F Z R O X cap F cap Z cap R cap O cap X𝐹𝑍𝑅𝑂𝑋 (Zero expense ratio) or F S K A X cap F cap S cap K cap A cap X𝐹𝑆𝐾𝐴𝑋 (Expense ratio ~ 0.0 1 5%)

Apply for the EIN: Ensure you have a separate EIN for your freelance business specifically for the Solo 401(k) trust (do not use your personal SSN or your regular business EIN if you are a single-member LLC using a different setup).
Open the Account: Complete the paperwork online with your chosen brokerage (like Fidelity Investments or Charles Schwab).
Make Contributions: As a freelancer, you can contribute as both the employee (elective deferrals up to the annual limit) and the employer (profit-sharing up to 2 5% of net earnings from self-employment).
Set Up Recurring Transfers / Trades: Link your business checking account, deposit your contributions, and execute trades for your chosen index funds. If you prefer a hands-off approach, buying broad market ETFs periodically or setting up automatic mutual fund purchases keeps your money working instantly without market-timing stress.[](https://choosefi.com/investing/low-cost-index-fund)
