Law firm income is
complicated. Your tax plan
should not be a reaction to it.

Law firm partners face a tax situation with several moving parts that interact in ways a generalist CPA rarely coordinates. Partnership income flows through K-1s at ordinary income rates — no preferential capital gains treatment, no FICA cap benefit, and in many firm structures, full self-employment tax exposure on guaranteed payments. The result is that law firm partners often pay more in effective tax rate than physicians earning comparable income through an S corporation structure.

The strategies below address the specific characteristics of attorney income — partnership K-1 treatment, origination and productivity allocations, self-employment surtax exposure, and the fact that many attorneys also own real estate that is generating passive losses they cannot currently use.

Law firm partners who receive guaranteed payments are subject to self-employment tax on those payments — currently 2.9% Medicare tax with no cap, plus the additional 0.9% Medicare surtax for high earners. On $500,000 of guaranteed payments, that is approximately $14,500 in additional tax that a hospital-employed physician would not pay.

The structure of the law firm partnership and how income is allocated between guaranteed payments, distributable share, and other categories directly affects the self-employment tax exposure. Some firms and partners have flexibility to optimize this; others do not. We analyze your firm's partnership agreement and your specific allocation to determine what, if any, restructuring or planning is available.

For partners in firms that operate through professional corporations or LLCs, S corporation elections at the individual partner's entity level — or management company structures — can create meaningful self-employment tax reduction. Each situation requires specific analysis.

A 401(k) allows $24,500 per year in contributions. For a law firm partner earning $750,000, that represents 3.1% of income — a rounding error in annual tax planning. A properly designed cash balance or defined benefit plan through the partner's professional corporation or partnership interest allows annual contributions — and immediate deductions — of $200,000 to $330,000+.

At a 37% marginal rate, a $265,000 annual contribution saves $98,050 in federal taxes. Over 10 years: $2.65 million sheltered, $980,500 in federal tax reduction. The money grows tax-deferred and is creditor-protected under ERISA — meaningful for attorneys who carry professional liability exposure.

For law firm partners who operate through a personal service corporation or individual firm entity, the plan can be established at that level even if the broader partnership does not offer one. We design the plan specifically for the partner's income structure, coordinate with an enrolled actuary, and manage the annual Form 5500 filing by its July 31 deadline.

Many attorneys own rental real estate — investment properties, commercial real estate, their own office buildings. Under the standard passive activity rules, losses from those properties cannot offset law firm partnership income. They sit as passive carryforwards — accumulating but producing no current benefit.

The spousal real estate professional election changes this for households where one spouse manages the real estate portfolio and meets the two-part test: 750+ hours per year in real property activities, and those hours represent more than 50% of total personal services. For an attorney spouse who manages the family's real estate holdings and has no other full-time profession, both tests are achievable with proper documentation.

Once the election is in place, cost segregation studies on every commercial property in the portfolio can generate hundreds of thousands of dollars in first-year deductions — all of which are immediately available against the attorney's partnership income rather than carrying forward indefinitely.

Law firm partnership interests are among the most estate-planning-friendly assets in the code — they can be transferred through Family Limited Partnerships at valuation discounts, through installment sales to grantor trusts without triggering capital gains, or through systematic annual gifting programs that move value out of the estate every year.

The SLAT for law firm partners: Each partner can transfer up to $15 million into a Spousal Lifetime Access Trust — permanently outside the estate, with the spouse retaining access through distributions. Both partners in a married couple each create a SLAT naming the other as beneficiary, deploying both $15 million exemptions. All future appreciation on partnership equity, investments, and other assets transferred to the SLATs grows outside the estate permanently.

Family Limited Partnership for investment assets: Law firm partners who have accumulated significant investment portfolios, real estate holdings, or other assets can contribute those to a Family Limited Partnership and begin systematic gifting of limited partner interests at 20–35% valuation discounts. The attorney retains complete management control as general partner while systematically moving economic ownership to heirs using discounted annual exclusion gifts.

Succession planning: For partners approaching retirement or contemplating a firm transition, the tax planning around that transition must begin well in advance — particularly any transfers of partnership goodwill or client relationships that could be characterized as personal goodwill and sold at capital gains rates rather than as ordinary income.
