Best for freelancers earning $100,000+ who can maximize contributions and want sophisticated investment options
Which Solo 401(k) provider is best for high-earning freelancers?
For freelancers earning $100,000+, the best Solo 401(k) providers are Fidelity, Charles Schwab, and Vanguard — all offering no annual account fees and access to low-cost index funds. Your choice depends primarily on investment preferences and whether you need plan loans.
Top 3 Solo 401(k) providers comparison
Fidelity leads for most freelancers due to zero account fees, zero minimum investment, and excellent customer service. Their FZROX (Total Market) and FXNAX (Bond) funds have 0.00% expense ratios, meaning a $50,000 balance pays $0 in fund fees annually.
Charles Schwab offers similar benefits with no account fees and strong index fund selection (SWTSX Total Stock Market at 0.03% expense ratio). However, they require $1,000 minimum investments in most funds, which can limit diversification for smaller accounts.
Vanguard charges a $20 annual account fee but offers the lowest-cost actively managed funds. Their Target Retirement funds (0.08% expense ratio) provide automatic rebalancing — valuable for busy freelancers.
Example: $150,000 freelancer maximizing contributions
Sarah, a freelance graphic designer earning $150,000, can contribute the full $70,000 Solo 401(k) limit in 2026:
At Fidelity, investing in FZROX costs her $0 in annual fees on a $61,000 contribution. At a traditional 401(k) provider charging 1% fees, she'd pay $610 annually — $6,100 over 10 years.
Key factors for provider selection
Advanced considerations for high earners
Mega backdoor Roth conversions: Only Fidelity and Schwab allow after-tax contributions beyond the $70,000 limit, enabling conversions up to $69,000 annually for ultra-high earners.
Alternative investments: Interactive Brokers offers Solo 401(k)s with access to individual stocks, options, and international markets — but charges $3/month plus trading fees.
Institutional platforms: E*Trade, TD Ameritrade, and others offer Solo 401(k)s but typically charge $25-50 annual fees without significant benefit over the top three.
What you should do
1. Start with Fidelity if you want simplicity and zero fees
2. Choose Schwab if you prefer their banking integration and don't mind $1,000 minimums
3. Pick Vanguard if you want target-date funds and don't mind the $20 fee
4. Avoid expensive providers charging 1%+ fees or complex commission structures
Open your account by December 31st to make contributions for the current tax year. You have until your tax filing deadline (including extensions) to make actual contributions.
Key takeaway: Fidelity offers the best combination of zero fees, zero minimums, and excellent fund selection for most high-earning freelancers. The difference between top providers and expensive ones can cost $500-1,000+ annually in unnecessary fees.
Key Takeaway: Fidelity, Schwab, and Vanguard are the top three Solo 401(k) providers, with Fidelity leading due to zero fees and minimums. Avoid providers charging 1%+ fees, which cost $500-1,000+ annually on typical balances.

Best for established freelancers with consistent income who want straightforward, low-cost retirement planning
Which Solo 401(k) provider should full-time freelancers choose?
As a full-time freelancer, your Solo 401(k) provider choice impacts your retirement savings for decades. Fidelity is typically the best choice because of zero account fees, zero investment minimums, and access to funds with 0.00% expense ratios.
Why provider choice matters for your long-term wealth
Consider two freelancers, both contributing $30,000 annually for 20 years:
The $40,000 difference comes entirely from fee savings compounded over time.
Practical comparison: Top 3 for freelancers
Fidelity: Zero fees, FZROX and FXNAX funds cost nothing in expenses. Best for freelancers who want to "set it and forget it." Customer service available 24/7.
Schwab: Zero account fees, excellent banking integration if you use Schwab checking. SWTSX Total Stock Market fund charges just 0.03%. Requires $1,000 minimum investment.
Vanguard: $20 annual fee but offers Target Retirement funds that automatically rebalance. Good for freelancers who don't want to manage their allocation.
What to avoid
High-fee providers: Many banks and insurance companies offer Solo 401(k)s with 1-2% annual fees. On a $50,000 balance, that's $500-1,000 per year in unnecessary costs.
Complex providers: Some promise exotic investments but charge setup fees, monthly maintenance fees, and transaction fees that quickly add up.
Getting started steps
1. Open account with Fidelity, Schwab, or Vanguard by December 31st
2. Choose 2-3 low-cost index funds or a target-date fund
3. Set up automatic contributions based on your quarterly estimated tax savings
4. Review and rebalance annually
Remember: You can contribute as both employee ($23,500 limit) and employer (25% of net SE income), potentially saving $15,000+ in taxes annually depending on your income and tax bracket.
Key takeaway: Fidelity's zero fees and minimums make it the top choice for most full-time freelancers. Focus on low-cost index funds rather than provider bells and whistles — fees compound against you over decades.
Key Takeaway: Provider fees compound over decades — choosing Fidelity over expensive providers can add $40,000+ to retirement savings over 20 years through fee avoidance alone.
