The Three Buckets of Retirement Planning for Law Firm Partners

Many law firm partners assume the value of their partnership will fund retirement. Sometimes it does. Often it doesn't.

A profitable practice isn't automatically a retirement plan. Whether decades of work become personal wealth depends on how a partner saves outside the firm, how compensation is structured along the way, and how ownership eventually converts into cash. It also depends on a detail most partners overlook: retirement contributions don't just defer taxes. For high-earning partners, they can sometimes restore deductions the partner assumed had already phased out.

This guide walks through retirement planning for law firm partners as three connected decisions rather than a single one: how you'll generate qualified retirement assets, how your firm's equity does or doesn't convert into retirement income, and how much of your overall net worth is actually liquid when you need it.

The Three Buckets of a Partner's Retirement

It's useful to think of a law firm partner's eventual retirement as being funded from three separate buckets, each of which behaves differently and requires its own planning:

1. Qualified retirement plans — 401(k)s, SEP IRAs, cash balance plans, and similar tax-advantaged accounts a partner and the firm contribute to directly.
2. Firm equity — the value of a partner's ownership interest, realized through a buyout, sale, or succession event.
3. Personal investments — taxable brokerage accounts, real estate, and other assets built up outside the firm entirely.

In our experience, the most common mistake isn't in any one bucket individually — it's the balance between them. Partners often overestimate how much Bucket 2 will provide and underfund Buckets 1 and 3 as a result, assuming the firm itself will make up the difference. The sections below take each bucket in turn.

Bucket One: Qualified Retirement Plans

Qualified retirement plans are the most obvious of the three buckets, since they're intentionally designed for retirement. How much a partner can put into one, though, depends heavily on how that partner is compensated, which in turn depends on the firm's entity structure. Partners in a traditional partnership or LLP typically receive guaranteed payments and a distributive share of income, reported on a K-1. Partners in a firm that's elected S corporation treatment may take a reasonable W-2 salary in addition to distributions.

That distinction matters because retirement plan contribution limits are calculated as a percentage of compensation, and plan documents define "compensation" differently depending on how a partner is paid. Consider two partners, each earning $700,000 in total economic benefit from the firm:

• Partner A takes most of that $700,000 as W-2 wages.
• Partner B, after an S election made primarily to reduce self-employment tax, takes a modest W-2 salary and the rest as distributions.

Even though both partners earn the same amount, Partner B's maximum retirement plan contribution can end up meaningfully lower — the exact impact depends on the specific plan design and how the plan document defines eligible compensation, but the entity election made to save on self-employment tax can simultaneously narrow retirement plan capacity if W-2 wages are set low relative to total earnings. That's a tradeoff worth modeling with your CPA before the election is made, not after. We've covered the broader tax mechanics in our articles on entity structure for law firms and partner compensation.

The plan menu itself generally comes down to three options:

Firms with partners at different ages and income levels often layer a 401(k) with profit sharing under a cash balance plan rather than relying on either alone. The right combination depends on the firm's partner and staff demographics as a whole, not any single partner's income.

Key Takeaway: An S corporation election can lower self-employment taxes, but if W-2 wages are set too low relative to total compensation, it may also reduce how much certain retirement plans allow that partner to contribute — a tradeoff worth modeling before, not after, the election is made.

How Retirement Contributions Interact With the QBI Deduction

Law firms are generally treated as a Specified Service Trade or Business (SSTB) under IRC Section 199A, which means the Qualified Business Income (QBI) deduction phases out for partners above certain income levels. Many partners assume that once their income clears the phaseout range, the deduction is simply gone for good.

That's not always true. Because retirement contributions reduce taxable income, a sufficiently large contribution — through a cash balance plan, for example — can in some cases bring a partner's taxable income back into a range where some QBI deduction becomes available again. We've explored the mechanics of this in QBI Adjustment for Retirement Plan Deductions.

Whether this makes sense depends on how far above the phaseout range a partner's income sits, how much of that gap a contribution could close, their tolerance for the cash outflow, and how many years remain until retirement — a calculation worth running with your CPA rather than assuming based on a rule of thumb.

Key Takeaway: A retirement contribution large enough to meaningfully reduce taxable income can do two jobs at once for a partner above the SSTB phaseout range — building retirement savings while potentially restoring some QBI deduction in the same year.

Bucket Two: Don't Assume Your Partnership Interest Will Fund Retirement

Qualified retirement plans are predictable because they're built for retirement on purpose. The second bucket — a partner's ownership interest in the firm — is often the largest number on their personal balance sheet, but it's considerably less predictable.

That's because "my partnership interest is worth something" and "my partnership interest will pay me a specific amount of money on a specific timeline" are very different statements. Some partners discover only a few years before retirement that the buyout they'd been counting on was never designed to replace decades of personal savings — it was designed to facilitate an orderly ownership transition, and the two goals don't always produce the same number.

Before assuming firm equity will fund any part of retirement, a few questions are worth answering honestly:

• Is the buyout actually funded, or does the partnership agreement simply promise a payment the firm will need to generate from future cash flow?
• What is the buyout based on — book value, collections over a trailing period, EBITDA, goodwill, or some formula unique to the firm? Each produces a very different number, and goodwill in particular is often excluded or heavily discounted in law firm agreements.
• Is there a mandatory retirement age, and does the payout timeline match a partner's actual retirement plans, or could it arrive years earlier or later than expected?
• What happens if the partner departs voluntarily versus involuntarily, or if the firm's profitability declines in the years leading up to the buyout?

Partnership agreements vary widely on all of these points, and provisions that seemed reasonable when a partner joined the firm may not reflect what that partner actually needs decades later. These terms are also far easier to renegotiate a decade before retirement than in the final year or two, when leverage has shifted. Coordinating a buyout with a partner's broader financial and estate picture is part of what we cover in our work with professional service firms.

Key Takeaway: A partnership interest only becomes retirement income if the buyout is funded and the formula behind it produces a number close to what a partner expects — assumptions worth testing against the actual partnership agreement well before retirement is close enough to matter.

Bucket Three: How Much of Your Net Worth Is Actually Liquid?

Retirement planning is often framed purely as a tax question — how much can be deducted, deferred, or sheltered. But a partner nearing retirement also needs to ask a more basic question: how much of my net worth can I actually spend?

Law firm partners frequently have significant value tied up in places that aren't readily accessible:

• Capital accounts, which typically can't be withdrawn on demand and are often returned only as part of a buyout or wind-down
• Partner loans, whether to the firm or from the firm to the partner, which carry their own repayment terms
• Buy-in obligations, if a partner financed their initial ownership stake and is still repaying it

A partner who has built substantial qualified retirement assets (Bucket One) but has most of their remaining net worth tied up across capital accounts, receivables, and an uncertain buyout (Bucket Two) may have far less flexibility heading into retirement than their total net worth suggests. Consider a partner with an $8 million net worth on paper: $4.5 million reflects the estimated value of their partnership interest, another $1 million sits in their capital account, $1.5 million is held in retirement accounts, and only $1 million is in cash and taxable investments. Even with an $8 million net worth, only a fraction of that wealth may be immediately available to fund the first years of retirement.

Personal investments held outside the firm — a taxable brokerage account, real estate, or other assets — are what typically provide the liquidity to bridge the gap between when a partner stops working and when firm-related payouts actually arrive.

Key Takeaway: Net worth and liquidity aren't the same thing for a law firm partner — a strong balance sheet built mostly from capital accounts, receivables, and a buyout still in progress may not translate into spendable income on the timeline retirement actually requires.

Where Revonary Fits In

The right retirement strategy for a law firm partner isn't selected always easy to ascertain. Entity structure, partner compensation, retirement plan design, the terms of your partnership agreement, and your personal liquidity all affect one another, often in ways that aren't obvious until they're looked at together. Most partners we work with have made real progress in one of the three buckets above and comparatively little in the other two, usually without realizing it.

At Revonary, we help law firm partners evaluate those tradeoffs before making decisions that can be difficult or expensive to unwind — whether that's an entity election that quietly narrows retirement plan capacity, a buyout formula that won't produce the number a partner expects, or a personal balance sheet that looks strong but isn't actually liquid when it needs to be. We help partners determine whether all three buckets are actually sufficient — not just individually, but together.
