3 Critical Decision Factors
- Time Horizon

- 20+ years? Solo 401(k) with Roth option provides tax diversification
- Employee Considerations
- SEP/SIMPLE IRAs require equal contributions for eligible employees
- Solo 401(k) avoids this until you have non-spouse employees
- Tax Strategy
- Current high tax bracket? Traditional contributions reduce taxable income now
- Expect higher future taxes? Roth options provide tax-free growth
Advanced Strategy: The Mega Backdoor Roth for Business Owners
How it works:
- Establish Solo 401(k) with after-tax contribution option
- Contribute up to $69,000 total (including employer contributions)
- Immediately convert after-tax funds to Roth IRA
Result: Up to $46,000 in annual Roth contributions beyond normal limits
Implementation Timeline
Q1: Set up Solo 401(k) or SEP IRA
Q2: Begin automatic contributions
Q3: Meet with actuary if considering defined benefit plan
Q4: Review contribution levels and adjust for next year
Common Mistakes to Avoid
❌ Waiting until December – Many plans must be established by October 1
❌ Ignoring state taxes – Some states don’t recognize all federal deductions
❌ Overlooking fees – Third-party administrators often charge 0.5-1.5% AUM
Final Recommendation
For most solopreneurs, the Solo 401(k) provides the best balance of high contributions and flexibility. If you:
- Have employees → Consider SIMPLE IRA
- Earn over $200K → Explore Defined Benefit plans
- Want ultimate simplicity → SEP IRA
