Keep More of What You Earn: The $83,250 Schwab Solo 401k Strategy
Watch: HOW-TO guide to maximizing your Solo 401k contributions using Schwab accounts with advanced plan features
If you’re self-employed and want to stop overpaying taxes and start building real retirement wealth, the Solo 401k offers the highest contribution limits available. When you combine Schwab’s excellent brokerage platform with My Solo 401k Financial’s advanced plan features, you can contribute up to $83,250 for 2026 (ages 60-63) or $80,000 (ages 50+) using the powerful Mega Backdoor Roth strategy.
Who’s Eligible for a Solo 401k?
To set up a Solo 401k, you must meet two key requirements:
Requirement #1: Self-Employment IncomeYou need to report earned self-employment income on your taxes. This can be:
- Schedule C income if your business is taxed as a sole proprietorship
- W-2 wages if your business is taxed as an S-Corp or C-Corp
- Line 14 K-1 income if your business is taxed as a partnership (Form 1065)
Good news: There is NO minimum income requirement to be eligible!
Requirement #2: No Full-Time W-2 EmployeesYou cannot have any non-owner, non-spouse full-time W-2 employees. A full-time w-2 employee is defined as someone age 21 or older who works:
- 1,000 hours per year or more with a year of service, OR
- 500 hours per year for two consecutive years
⚡ Important Note:You can have a Solo 401k even if you have a W-2 day job and participate in your employer’s 401k plan! As long as you have separate self-employment income (from freelancing, consulting, side business, etc.) with no full-time employees, you’re eligible.
Common eligible professions include realtors, freelancers, independent contractors, consultants, interior designers, photographers, writers, coaches, and anyone operating a side business.
The Schwab Advantage: Best of Both Worlds
Schwab is one of the top choices for Solo 401k account custody, offering excellent investment options, low fees, and robust trading platforms. However, if you open a Solo 401k directly with Schwab, you’ll get a basic “vanilla” plan with significant limitations.
What Schwab’s Basic Solo 401k DOESN’T Include:
💡 The Solution: Have Your Cake and Eat It TooYou can use Schwab for custody (where your money is held and invested) while having your Solo 401k plan documents provided by My Solo 401k Financial. This gives you:
- ✅ Access to Schwab’s investment platform
- ✅ Advanced plan features (Mega Backdoor Roth, loans, alternatives, etc.)
- ✅ $1,500 in tax credits under the SECURE Act
- ✅ Expert hands-on support for account setup and Solo 401k compliance
My Solo 401k Financial is completely neutral about where you custody your accounts. The plan is fully portable and can be used with any bank or brokerage of your choice.
2026 Solo 401k Contribution Limits: Up to $83,250
The Solo 401k has the highest contribution limits of any retirement plan available to self-employed individuals. Here’s why: as a self-employed person, you’re BOTH the employee AND the employer, so you can make multiple types of contributions.
Understanding the Three Contribution Types
🎯 Key Concept: The Overall LimitFor 2026, the overall Solo 401k contribution limit is $72,000. This limit includes:
- Employee contributions (standard $24,500)
- Employer contributions (profit-sharing)
- After-tax contributions (for Mega Backdoor Roth)
Important: Catch-up contributions ($8,000 or $11,250) are ON TOP of the $72,000 limit!
Calculating Employer Contributions: It Depends on Your Business Structure
Your ability to make employer contributions depends on how your business is taxed. The percentage you can contribute varies by entity type:
💡 Pro Tip:My Solo 401k Financial provides a free contribution calculator on their website and helps clients run these calculations daily. The calculation for sole proprietors and partnerships requires a pre-calculation to determine your adjusted self-employment compensation.
The Mega Backdoor Roth Strategy: Unlocking Maximum Tax-Free Growth
The Mega Backdoor Roth is the secret weapon that allows high-earning solopreneurs to get significantly more money into Roth accounts for tax-free growth. Here’s how it works:
Step 1: Make After-Tax Contributions
With a Solo 401k plan from My Solo 401k Financial, you can make voluntary after-tax contributions up to 100% of your self-employment compensation, dollar for dollar, up to the $72,000 overall limit (minus any employee/employer contributions already made other than catch-up contributions).
Example:If you’re under age 50 and choose NOT to make employee or employer contributions, you could contribute up to $72,000 as voluntary after-tax contributions (assuming you have at least $72,000 in self-employment compensation to justify it).
Step 2: Convert to Roth
After making the after-tax contribution to a separate after-tax Solo 401k account, you immediately transfer those funds to either:
- Roth Solo 401k account (in-plan Roth conversion), OR
- Roth IRA (external conversion)
Once the money is in the Roth account, it can be withdrawn tax-free in retirement if withdrawn as a qualified Roth distribution!
⚠️ Critical Requirement:You MUST have plan documents that allow BOTH steps:
- Making voluntary after-tax contributions, AND
- Converting/transferring to Roth
Schwab’s standard Solo 401k does NOT support this. You need the advanced plan documents from My Solo 401k Financial.
The Complete $83,250 Schwab Solo 401k Strategy (Ages 60-63)
Let’s put it all together with a real-world example for someone aged 60-63 in 2026 with $100,000 in self-employment compensation (i.e. Line 31 of Sched C less one-half of the self-employment tax) from a business taxed as a sole proprietorship:
✨ The Magic Formula:$83,250 total contribution from just $100,000 in self-employment income!
For Ages 50-59: The $80,000 Strategy
If you’re aged 50+ but not yet 60, you can still contribute up to $80,000 using the same approach:
Important Reminders and Considerations
📋 Key Points to Remember:
- You can’t contribute more than you earn – your total contributions are limited by your self-employment compensation
- The $72,000 limit is cumulative – it includes employee, employer, and after-tax contributions combined
- Catch-up contributions are EXTRA – they don’t count toward the $72,000 base limit
- Plan documents matter – Schwab’s basic plan won’t support Mega Backdoor Roth
🎁 Don’t Forget: $1,500 in Tax Credits!When you set up a Solo 401k with My Solo 401k Financial, you can claim up to $1,500 in tax credits under the SECURE Act. This is money back in your pocket – a direct reduction in your tax bill, not just a deduction!
