Top 3 Retirement Plan Options for Solo Attorneys in 2026
Executive Summary & Key Points
The Big Picture
Many solo attorneys spend years building successful practices but put retirement planning on the back burner. Between managing clients, court deadlines, and firm operations, retirement often feels like something that can wait.
The problem is that delaying retirement planning can lead to higher taxes and missed wealth-building opportunities. The right retirement plan can help you reduce taxable income today while creating long-term financial security. For many solo attorneys, retirement planning is one of the most effective tax strategies available.
The Cheat Sheet
- A Solo 401(k) is often the most flexible retirement plan for solo attorneys.
- A SEP IRA offers simplicity but may not maximize contributions.
- A Defined Benefit Plan can create substantial tax deductions for high-income attorneys.
- Retirement planning should be coordinated with your overall tax strategy.
- Waiting until tax season can limit your retirement planning options.

The Business of Law and Retirement Planning
Solo attorneys are responsible for more than practicing law. They are also responsible for managing finances, controlling expenses, generating revenue, and planning for the future.
Unlike attorneys working in large firms, solo practitioners do not typically have employer-sponsored retirement plans. That means the responsibility for retirement savings falls entirely on the business owner.
Many attorneys focus on growing revenue while overlooking opportunities to reduce taxes and build wealth. As income increases, so does the importance of having a retirement strategy in place.
The attorneys who achieve long-term financial success typically treat retirement planning as part of their overall business strategy. They understand that every dollar saved in taxes and invested wisely can create meaningful financial growth over time.
Option #1: Solo 401(k)
Why It Matters
For many solo attorneys, the Solo 401(k) offers the best combination of flexibility, contribution limits, and tax savings.
How It Works
A Solo 401(k) is designed for self-employed business owners who do not have full-time employees other than a spouse.
Key benefits include:
- Contributions as both the employee and employer
- High annual contribution limits
- Tax-deferred investment growth
- Flexibility in contribution amounts
- Potential Roth contribution options
This structure allows solo attorneys to save aggressively while reducing taxable income.
CPA Pro Tip
Many solo attorneys assume a SEP IRA is automatically the best choice because it is simple to set up. However, as we discuss in our SEP IRA vs. Solo 401(k) comparison, Solo 401(k) plans often allow substantially larger contributions at lower income levels because they permit both employee and employer contributions.
For attorneys focused on maximizing deductions, this difference can be significant. Before selecting a retirement plan based solely on simplicity, compare the contribution opportunities available under each option.
Option #2: SEP IRA
Why It Matters
The SEP IRA remains one of the easiest retirement plans for solo attorneys to establish and maintain.
How It Works
SEP stands for Simplified Employee Pension.
Key benefits include:
- Simple setup process
- Minimal administrative requirements
- Flexible annual contributions
- Tax-deductible contributions
A SEP IRA works well for attorneys who want a straightforward retirement solution without ongoing administrative responsibilities.
CPA Pro Tip
Simplicity should not be the only factor in choosing a retirement plan. Many attorneys discover they could contribute significantly more through a Solo 401(k), resulting in larger tax deductions and faster retirement savings growth.
And keep in mind that if you add employees you will need to offer the same plan to them. We find that a SEP IRA works best for small teams with staff you want to provide extra benefits for.
Option #3: Defined Benefit Plan
Why It Matters
For high-income solo attorneys, a Defined Benefit Plan may offer the largest retirement contributions and tax deductions available.
How It Works
A Defined Benefit Plan is designed to provide a specific retirement benefit rather than relying solely on annual contribution limits.
Benefits include:
- Very large contribution potential
- Significant tax deductions
- Accelerated retirement savings
- Increased benefits for older attorneys
- Ability to pair with other retirement strategies in certain situations
Contribution amounts are determined through actuarial calculations based on age, income, and retirement objectives.
CPA Pro Tip
Defined Benefit Plans work best for attorneys with consistent profits and a strong commitment to annual funding requirements. They are powerful tools but require more planning and administration than other retirement options.
We typically only recommend these plans if you are the only participant and you want to put potentially six figures into your retirement each year.

How to Choose the Right Retirement Plan
Why It Matters
The best retirement plan is not always the one with the largest contribution limit. The right choice depends on your firm’s profitability, personal goals, team size, and tax planning objectives.
How It Works
Consider these questions:
- How much profit does your firm generate each year?
- Do you want maximum flexibility or maximum deductions?
- How close are you to retirement?
- Is your income consistent year after year?
- Do you have employees now?
- Do you expect to hire employees in the future?
General guidelines include:
- SEP IRA: Best for simplicity
- Solo 401(k): Best for flexibility and balanced tax savings
- Defined Benefit Plan: Best for maximizing deductions
CPA Pro Tip
Retirement planning should be reviewed annually. As your income grows, the retirement plan that worked five years ago may no longer be the most effective option.
Tax Savings Opportunities Beyond Retirement Contributions
Why It Matters
Retirement plans are powerful, but they are only one part of a comprehensive tax strategy.
How It Works
Retirement planning often works alongside:
- S Corporation tax strategies
- Accountable plans
- Health Savings Accounts (HSAs)
- Strategic compensation planning
- Business expense optimization
When combined properly, these strategies can significantly reduce tax liability while improving cash flow.
CPA Pro Tip
The biggest tax savings rarely come from one strategy alone. They come from coordinating multiple strategies throughout the year rather than scrambling for deductions during tax season.
Additional Considerations: Commonly Missed Opportunities
Many solo attorneys leave money on the table because they overlook key retirement planning opportunities.
Common mistakes include:
- Waiting until year-end to evaluate retirement options
- Failing to review contribution limits annually
- Choosing a plan based only on ease of setup
- Missing employer contribution opportunities
- Not coordinating retirement planning with tax planning
- Ignoring spouse participation opportunities when available
Small mistakes can compound over time. A missed contribution opportunity today can mean significantly less retirement wealth decades from now.
The most successful law firm owners proactively review their retirement strategy throughout the year and adjust it as their business evolves.
Frequently Asked Questions
Q: What is the best retirement plan for solo attorneys?
A: For many solo attorneys, the Solo 401(k) provides the best balance of flexibility, tax savings, and contribution opportunities. However, higher-income attorneys may benefit more from a Defined Benefit Plan. Consult your tax advisor for specific recommendations.
Q: Can I have both a Solo 401(k) and a Defined Benefit Plan?
A: In some situations, yes. Combining these plans may allow for significantly larger retirement contributions and tax deductions. A CPA should evaluate whether this approach fits your specific circumstances.
Q: Is a SEP IRA better than a Solo 401(k)?
A: Not necessarily. SEP IRAs are simpler to administer, but Solo 401(k)s often allow larger contributions at lower income levels. Comparing both options is essential before making a decision.
Q: How much can a solo attorney contribute to retirement plans in 2026?
A: Contribution limits vary by plan type and are adjusted periodically. Working with a CPA helps ensure you maximize contributions while staying compliant with IRS rules.
Q: When should I set up a retirement plan?
A: The earlier, the better. Establishing a plan before year-end provides greater flexibility for tax planning and retirement contributions. And some plans have specific set up dates during the year. If you miss those deadlines you have to wait until the following year.
Q: What if my income changes significantly each year?
A: Attorneys with fluctuating income often benefit from flexible retirement plans such as a Solo 401(k) or SEP IRA. The right choice depends on your overall financial goals.
Q: Should retirement planning be part of tax planning?
A: Absolutely. Retirement plans are among the most effective tax-saving tools available to solo attorneys. Coordinating retirement planning with tax planning generally produces the best financial outcome.
Conclusion
Retirement planning is about more than preparing for the future. For solo attorneys, it is also one of the most effective ways to reduce taxes and strengthen long-term financial performance.
The attorneys who achieve the strongest financial results rely on systems rather than guesswork. They review retirement plans regularly, coordinate them with broader tax strategies, and make proactive decisions throughout the year.
Whether you choose a Solo 401(k), SEP IRA, or Defined Benefit Plan, the key is selecting a strategy that supports both your personal financial goals and the continued growth of your law firm.
