I had a conversation last summer with a Chicago solo attorney that's stayed with me. He sat down with me in mid-July, looked at his books for the first time in five months, and realized he was on track to clear something close to $475,000 for the year. He had no idea. His CPA didn't know either — they hadn't talked since March.

The next thing he said was, "Well, I guess I'll deal with it in January."

By April of the following year, he wrote a check to the IRS for a number that would have made him sick if he'd stopped to think about it the previous July. What he didn't know then — and what most solo attorneys don't know in July — is that he had every legal tool available to defer well over $250,000 of that income into accounts that would compound for him instead of his lifestyle. He just needed to know to act, and he needed to do it before December 31st.

$250K+
The amount a solo attorney can legally defer before the IRS sees a penny — with the right structure in place before December 31st. Most never find out this is possible.

This is the most common — and most expensive — pattern I see in the solo practices I've worked with for 24 years. Smart, capable attorneys who would never let a case deadline slip will let an entire tax year slip past them every single year. Not because they don't care. Because nobody ever explained to them that the middle of the year is when the door is still open.

Why Midyear Is the Right Window

Why is midyear the right time for a solo attorney to do tax planning?

Midyear is the only time during the year when a solo attorney has enough revenue data to project the year's finish and enough remaining runway to act on it. The calendar gives you exactly one window when both conditions exist at the same time.

The Planning Window
January
All runway, no data. Can't plan in the specific.
June–August ✓
Six months of data. Five months of runway. Both conditions hold.
April
All data, no runway. You're reporting, not planning.

By June or July, a solo attorney has six months of receipts, six months of payments, and a real read on what kind of year it's going to be. But there are still five or six months left to act. Five months is enough time to open a solo 401(k) that wasn't open in March. Five months is enough time to design a cash balance plan with an actuary. Five months is enough to change the answer in April.

The Five Questions

1 Question One

Where am I going to finish the year — and what does my tax picture look like if I do nothing?

This is the foundation question, and most solo attorneys cannot answer it.

Before you can plan anything, you need a clear-eyed projection: revenue, expenses, net income, and an estimate of what your federal and state tax liability will look like if you change nothing between now and December. For a solo at the federal top marginal rate of 37%, plus Illinois' 4.95% flat rate, plus self-employment tax, the effective bite on every additional dollar can land north of 45%.

The honest version of this question is: If I do nothing different for the rest of the year, how big is the check I'm writing next April?

If you can't answer that with a real number — not a guess — then no strategy below this point will help you, because you have no baseline to measure against. This is where most solos stop. And the missing piece almost always isn't tax knowledge; it's the financial infrastructure to even have current numbers in front of you.

2 Question Two

Am I using the right foundational retirement vehicle for my income level?

For self-employed attorneys in 2026, the foundational vehicles are the Solo 401(k), the SEP-IRA, and the SIMPLE IRA. A solo using the wrong one is leaving real money on the table every year.

Vehicle 2026 Max Best For
Solo 401(k) $72,000 ($80,000 age 50+; $83,250 age 60–63) Most solo attorneys — highest ceiling with employee deferral
SEP-IRA $72,000 (employer side only) Solos who need simplicity or set up retroactively at filing
SIMPLE IRA $17,000 Early-stage solos; outgrown quickly above $300K income

The Solo 401(k) is the most powerful of the three for most solo attorneys. Per Fidelity's 2026 contribution guidance, a solo can contribute up to $24,500 as the employee plus an employer profit-sharing contribution of up to 25% of net self-employment income — combined ceiling $72,000. The IRS confirms these limits in its 401(k) and profit-sharing plan contribution guidance.

One important 2026 change: under SECURE 2.0, if you are age 50 or older and earned $150,000 or more in the prior year, your catch-up contributions must now be made on a Roth basis — not pre-tax. If your plan does not support Roth contributions, you may not be able to make catch-up contributions at all in 2026.

The midyear question isn't just "do I have a retirement plan?" It's whether the plan you have is the right one for your income level — and whether you're actually using it to its full capacity.

3 Question Three

Am I a candidate for a cash balance plan?

This is the question almost no solo attorney is asked — and it's where the numbers get serious.

A cash balance plan is a type of defined benefit pension plan that sits on top of your Solo 401(k) or SEP. Where a 401(k) is governed by a flat annual ceiling, a cash balance plan's contribution is calculated by an enrolled actuary based on your age, income, and target retirement benefit. The older you are and the closer you are to your target retirement date, the larger the contribution — and the larger the deduction.

According to Pension Deductions' 2026 guide, a 55-year-old professional with $300,000+ in consistent compensation can shelter approximately $200,000 per year through a cash balance plan, on top of their 401(k). The IRS Section 415(b) maximum annual benefit limit is $290,000 for 2026, and the lifetime accumulation cap sits around $3.7 million.

Who is the right candidate? Generally, attorneys over 45 with consistent compensation of $200,000 or more who have already maxed out their 401(k) and want substantial additional tax deferral. The midyear question isn't whether you should set one up — it's whether you've ever even been told this exists.

"The standard menu — 401(k), SEP, IRA — is the starting point, not the ceiling. Most solos never get past it because nobody told them there was more to the menu."
4 Question Four

What about the creative vehicles I've never heard of?

Beyond the standard menu, there is a tier of strategies most solos discover by accident, if at all. The right one depends entirely on the attorney's practice area, income structure, and personal financial picture.

Backdoor Roth and mega backdoor Roth conversions. For high earners whose income disqualifies them from contributing directly to a Roth IRA, the backdoor Roth — a nondeductible traditional IRA contribution converted to a Roth — remains a legal workaround. The mega backdoor Roth, available in some Solo 401(k) plans, allows after-tax contributions that can be converted to Roth, dramatically expanding tax-free retirement savings beyond standard limits.

Health Savings Accounts (HSAs) as a stealth retirement account. If you're enrolled in a high-deductible health plan, the HSA is the only account in the U.S. tax code with triple tax advantages: contributions are deductible, growth is tax-free, and qualified medical withdrawals are tax-free. Solos who treat their HSA as a long-term investment account — rather than a year-to-year medical fund — can build a significant tax-free retirement bucket over time. See Fidelity's self-employed retirement options guide for more on structuring this alongside a Solo 401(k).

Attorney fee deferral. This one is specific to contingency-fee attorneys — plaintiffs' lawyers in personal injury, employment, and similar practices — and traces back to the Tax Court ruling in Childs v. Commissioner, 103 T.C. 634 (1994). Through a structured arrangement at settlement, an attorney can defer receipt of contingency fees over multiple years, deferring the income tax on those fees until payments are received. Industry guides describe this as functionally equivalent to an uncapped 401(k), with the potential to double the after-tax value of a fee through tax deferral, bracket smoothing, and pre-tax growth.

Charitable strategies. Donor-advised funds, charitable lead trusts, and qualified charitable distributions (for attorneys over 70½ with IRAs) all offer tax-advantaged ways to support causes the attorney already gives to — often at substantially higher pre-tax dollar values than direct gifts of cash.

5 Question Five

Are my CPA, financial advisor, and admin function actually talking to each other?

This is the question that costs solo attorneys the most money — and almost none of them are aware of it.

I watched a solo last spring discover that his CPA had been quietly assuming there was a Solo 401(k) in the picture for two years. There wasn't. His financial advisor had never asked, because the financial advisor was managing a brokerage account and had no reason to know what was happening on the tax side. Two years of $50,000-plus contributions, untaken. Nobody had done anything wrong, exactly. Nobody had been talking to each other either.

A typical solo has three financial professionals in their orbit — a CPA, a financial advisor, and (if they're lucky) a bookkeeper or admin. These three people almost never talk to each other. The CPA sees the year only after it's over. The financial advisor sees the brokerage statement but not the firm's cash position. The bookkeeper sees the firm's cash position but not the retirement strategy.

The fix is not complicated. It is one mid-year meeting — June or July — with all three professionals at the same table (or on the same call), looking at the same projection. It takes an hour. It tends to identify five-figure tax savings the solo would have otherwise missed. And almost no solo does it.

Why This Falls Apart Every Year

Why does this fall apart every year for solo attorneys?

Because nobody is responsible for it.

A solo attorney with no admin function is wearing every hat in the firm: rainmaker, lawyer, billing department, AR collector, HR, IT, and CFO. The CFO hat is the one that gets dropped, every time, because none of the others can be dropped. The books are six months stale. And by the time the year ends, the financial picture the attorney needs in order to do any of the planning above doesn't exist in a form anyone can use.

This isn't a character flaw. It's a structural problem. A solo running a practice without a back office cannot generate the visibility required to do real tax planning. They can buy individual services — a CPA, a financial advisor — but those services are downstream of the data. If the data isn't there, the services produce general advice instead of specific action.

In full disclosure, this is exactly the gap Amata's Fractional Services was built to close. Our fractional admin and bookkeeping programs put a part-time, on-site team behind a solo practice — handling billing, AR, books, and the financial reporting that makes midyear planning possible in the first place. The attorney doesn't become the CFO. They get one.

The wealth management piece comes second. The infrastructure to know your numbers comes first. Most solos who get the order wrong end up with great financial advice they can't act on.

One important note Steve made on the show, and worth ending on here: Mesirow does not provide legal or tax advice, and neither does Amata. Everything above is general education. Anything you do with it should run through your own CPA and your own financial advisor — both of whom should be in the same room when it does.

The expensive thing about midyear isn't the tax bill itself. It's that the window to change the answer closes a little more every week between now and December. Every year a solo attorney spends running heads-down on billables without asking these five questions is a year that produces income they couldn't keep.

The work compounds. So does the cost of skipping it.
