Attorneys often face a unique tax challenge. As high-income earners, they frequently find themselves in the top tax brackets, where nearly 40% of their incremental earnings can go toward federal and state taxes. For many legal professionals, especially those who operate as partners in a firm or as solo practitioners, the income they receive is not a simple salary. Instead, it is often reported via a Schedule K-1.

To keep more of what they earn, savvy attorneys use advanced retirement structures like the Solo 401(k) and the Self-Directed IRA. These tools do more than save for retirement. They act as powerful tax shields that can significantly offset taxable income.

How Attorneys Get Paid

Before understanding how to save on taxes, an attorney must understand how they are compensated. In the legal world, payment structures usually fall into two categories depending on the firm’s business entity type.

W-2 Wages (S-Corporations): If an attorney operates as an employee of their own S-Corporation, they receive a W-2. This is a standard salary where taxes are withheld throughout the year. While the S-Corp might also pass through profits via a K-1, retirement contributions are primarily calculated based on the W-2 salary portion.

K-1 and Guaranteed Payments (Partnerships): Many law firms are structured as partnerships or LLCs taxed as partnerships. In this scenario, partners do not receive a salary in the traditional sense. Instead, they receive guaranteed payments or a distributive share of the firm’s profits, both of which are reported on Schedule K-1.

Earned Income vs. Passive Income

A critical rule in the tax code is that you must have earned income, also called compensation, to contribute to a retirement plan.

Compensation includes W-2 wages, professional fees, and net earnings from self-employment, typically found in Box 14 of a K-1. If you are actively practicing law, this income is compensation.

Passive income includes rental income, dividends from stocks, or interest. If you are a silent partner in a firm and do not provide legal services, that income is passive.

The distinction matters for one specific reason. Only compensation can be used to calculate how much you can put into a Solo 401(k) or an IRA. However, the deduction generated by those contributions lowers your total Adjusted Gross Income (AGI), which effectively reduces the tax you pay on both your compensation and your passive income.

What Is a Solo 401(k)?

The Solo 401(k) is a retirement plan covering a business owner with no employees. It is specifically designed for self-employed individuals and small law firms with no full-time employees other than the owner and their spouse.

Who is eligible?

For attorneys, the Solo 401(k) is available to solo practitioners, partners with no direct employees, and attorneys with side income from consulting or expert witness testimony.

2026 Contribution Limits

One of the biggest advantages is that attorneys can contribute as both the employee and the employer.

A few features worth highlighting:

• Pre-Tax or Roth: Most attorneys choose pre-tax deferrals to lower their current tax bill, though Roth is available for tax-free growth
• Loan feature: You can borrow up to $50,000 or 50% of the account value without triggering taxes or penalties
• Mega Backdoor Roth: Attorneys can make after-tax contributions and convert them to Roth, potentially moving a significant amount annually into a tax-free environment
• Alternative assets: A Self-Directed Solo 401(k) allows investments in real estate, private equity, precious metals, and more

Reducing Taxable Income: How the Deduction Works

When an attorney makes a pre-tax contribution, the IRS treats that money as if it was never earned. If an attorney earns $300,000 through their K-1 and contributes $72,000 to their Solo 401(k), their taxable income drops to $228,000. At a 35% tax rate, that single contribution produces a $25,200 reduction in their tax bill.

That is not a small number. And for attorneys in higher brackets or higher-tax states, the combined federal and state savings can be substantially larger.

Traditional IRA: 2026 Deductions and Rules

A Traditional IRA provides a deduction that reduces your AGI. For 2026, the contribution limit is $7,500, with a $1,100 catch-up for those age 50 and older, bringing the total to $8,600. Withdrawals are taxed as ordinary income and must begin at age 73, increasing to 75 under the SECURE Act 2.0 timeline.

Eligibility income limits for pre-tax deductions

If you or your spouse have access to a 401(k) at work, your ability to take a deduction is limited by your AGI:

• Single filers: Full deduction if AGI is $81,000 or below; phases out up to $91,000
• Married filing jointly: If the contributing spouse has a 401(k), the deduction phases out between $129,000 and $149,000
• No workplace plan: If neither spouse has access to a 401(k) plan at work, there are no income limits to receive a full pre-tax deduction

Not All IRAs Are the Same

While a standard IRA at a retail bank typically limits you to stocks, bonds, and mutual funds, a Self-Directed IRA is a powerful alternative for attorneys who want more control over their capital. It is a regular IRA, either Traditional or Roth, held by a specialized custodian that allows for a much broader range of alternative assets.

Investment options

A true Self-Directed IRA allows for a variety of alternative investments including:

• Real estate: Commercial buildings, residential rentals, or raw land
• Tax liens and notes: Tax lien certificates or promissory notes where the IRA acts as a private lender
• Private placements: Startups, private equity funds, or other private deals
• Precious metals and crypto: Physical gold, silver, or digital assets like Bitcoin

What you cannot invest in

Despite its flexibility, the IRS prohibits certain investments in a Self-Directed IRA:

• Life insurance contracts
• Collectibles such as artwork, antiques, gems, stamps, or alcoholic beverages
• S-Corporation stock
• Any asset involving a prohibited transaction with a disqualified person, which includes yourself, your spouse, your children, or any entity 50% or more controlled by such persons

The prohibited transaction rules are one of the most important compliance areas for Self-Directed IRA investors. A single violation can disqualify the entire account.

Why the Solo 401(k) Is the Best Plan for Lawyers

The Solo 401(k) is the gold standard for legal professionals for one straightforward reason: the contribution limits are dramatically higher than any other plan available to self-employed attorneys.

In a corporate 401(k), an employer might match 3% or 4% of your salary. With a Solo 401(k), your employer contribution, made by you as the business owner, can reach 20% to 25% of your compensation. That creates a massive annual deduction that far exceeds what a traditional IRA or corporate plan can offer on its own.

Final Thoughts

The most tax-efficient approach for attorneys combines both tools. By stacking a Solo 401(k) contribution up to $83,250 with a pre-tax IRA contribution of $8,600, a lawyer can shield nearly $91,850 of their K-1 income from taxation in a single year. It is worth noting that IRA deductibility phases out at higher income levels if a workplace plan is available, so the combined maximum depends on your specific income and filing situation.

While only earned compensation can be used to fund these plans, the resulting deductions lower your total AGI, effectively reducing the tax burden on both your compensation and any passive income you receive. For attorneys in the top brackets, that combination is one of the most powerful legal tax reduction strategies available.
