Law Firm Partner Compensation: Guaranteed Payments, Distributions, and Self-Employment Tax

A partner in a law firm taxed as a partnership gets paid through two channels, and both are self-employment income. A guaranteed payment under IRC 707(c) is a fixed amount for services, paid whatever the firm earns. The distributive share is the partner’s slice of what’s left, set by the partnership agreement under IRC 704. Both land on Schedule K-1 and both go on Schedule SE at 12.4% Social Security up to $184,500 for 2026, 2.9% Medicare on all of it, and 0.9% more above $200,000. There’s no W-2, no withholding, and the draws you take during the year aren’t the income you’re taxed on.

What’s a guaranteed payment versus a distributive share?

A guaranteed payment is pay that doesn’t depend on how the firm did. IRC 707(c) treats payments to a partner “for services or the use of capital,” to the extent “determined without regard to the income of the partnership,” as if paid to an outsider for gross income and deduction purposes. The firm deducts it like a salary. The distributive share is the opposite: the partner’s percentage of the firm’s remaining income, which IRC 704(a) says is “determined by the partnership agreement.”

Item	Where it shows on the K-1	Depends on firm profit?	Deducted by the firm?	Self-employment tax?	Capital account effect	Authority
Guaranteed payment for services	Box 4a (Box 4c is the total with capital payments)	No	Yes, as an expense	Yes	Up when allocated as income, down when the cash goes out	707(c), K-1 instructions
Distributive share of ordinary income	Box 1	Yes	No, it’s an allocation of what’s left	Yes, for a partner who practices	Up by the allocation	704(a), 1402(a)
Draw or distribution	Item L, “withdrawals and distributions”; never an income box	n/a	No	No	Down; taxable only if cash exceeds basis	731(a)(1)

• “$300,000 a year for services” is a guaranteed payment. “30% of net income” is a distributive share. “$300,000 plus 10% of net income above $2 million” is one of each, and the K-1 splits them into Box 4a and Box 1.
• The Partner’s Instructions for Schedule K-1 define Box 4a as “guaranteed payments for services performed for the partnership. Guaranteed payments are payments to a partner determined without regard to partnership income.” Box 1 is “your share of the partnership’s ordinary business income (loss).”
• The guaranteed payment creates a floor and the other partners absorb it. If the firm nets $200,000 before a $240,000 guaranteed payment, the partner with the guarantee still gets $240,000 and the remaining partners share a $40,000 loss through their distributive shares.
• Allocations have to have substantial economic effect. IRC 704(b) lets the IRS reallocate where the agreement’s allocation “does not have substantial economic effect,” which in practice means the capital accounts have to track the allocations and the agreement has to liquidate by capital accounts. Lockstep, eat-what-you-kill and hybrid formulas all work as long as the books follow them.

Why can’t a law firm partner be paid as an employee?

Because for employment-tax purposes a partner is the business, and the firm can’t be the partner’s employer. The rule is written into Treas. Reg. 301.7701-2(c)(2)(iv)(C): even where a partnership runs its practice through a disregarded LLC, that entity “is not the employer of any partner of the partnership that owns the entity,” and a partner “is subject to the same self-employment tax rules as a partner of a partnership that does not own” such an entity. Routing partner pay through a management company W-2 doesn’t change the answer.

• No withholding. The partner pays quarterly estimates covering income tax and self-employment tax. IRC 6654(a) adds an underpayment charge, avoided by paying the lesser of “90 percent of the tax shown on the return for the taxable year” or “100 percent of the tax shown on the return of the individual for the preceding taxable year” (110% for higher earners, a detail your preparer handles).
• No employer FICA. The partner pays both halves through self-employment tax and gets half back as a deduction under IRC 164(f).
• Health insurance is still deductible, above the line. IRC 162(l) allows a self-employed individual a deduction for “insurance which constitutes medical care” for the taxpayer, spouse, dependents and children under 27, capped at the earned income from that business.
• Retirement plan contributions are based on net self-employment earnings rather than a salary, which changes the arithmetic (below).
• The small-firm exception is the S-corp election, where the owners become W-2 shareholder-employees and only the salary carries FICA. That’s an entity decision, covered in the law firm entity structure guide.

How does self-employment tax work on partner income?

Everything a practicing partner receives from the firm is net earnings from self-employment. IRC 1402(a) includes the partner’s “distributive share (whether or not distributed)” of partnership business income, and guaranteed payments for services come in the same door. The tax is computed on 92.35% of that figure, then 12.4% up to the Social Security base ($176,100 for 2025, $184,500 for 2026), 2.9% on the whole amount, and 0.9% Additional Medicare above $200,000 single or $250,000 joint.

• The rates are in IRC 1401: “12.4 percent,” “2.9 percent,” and “0.9 percent of the self-employment income for such taxable year which is in excess of” $250,000 joint or $200,000 otherwise. The 2026 base is in Publication 15 (“The social security wage base limit is $184,500”); the 2025 base in the Schedule SE instructions.
• The 92.35% comes from IRC 1402(a)(12), a deduction equal to net earnings times “one-half of the sum of the rates imposed by subsections (a) and (b) of section 1401,” which is 7.65%.
• Half the tax comes back as an income-tax deduction: IRC 164(f) allows “one-half of the taxes imposed by section 1401 (other than the taxes imposed by section 1401(b)(2)),” so the 0.9% Additional Medicare layer is excluded from the half.
• The limited-partner carve-out in 1402(a)(13) excludes “the distributive share of any item of income or loss of a limited partner, as such,” but never guaranteed payments for services. Whether an LLP partner who practices full time is a limited partner “as such” is contested, and the conservative reading, which is also what the IRS expects, is that a working partner’s whole share is self-employment income.

What’s the difference between a draw and a distribution?

A draw is an advance against the income the K-1 will allocate. It isn’t income, and the partner who takes $300,000 of draws but is allocated $400,000 owes tax on $400,000. A distribution is the same cash seen from the firm’s side: it reduces the partner’s capital account and basis. Under IRC 731(a)(1) no gain is recognized on a cash distribution “except to the extent that any money distributed exceeds the adjusted basis of such partner’s interest in the partnership immediately before the distribution.”

• Any gain that is recognized is treated as gain from selling the partnership interest, which is how a partner ends up with a capital gain on money that felt like pay.
• The capital account starts with what the partner put in, rises with allocated income and contributions, and falls with distributions and allocated losses. Draws that run ahead of allocations for a few years push it negative, and that’s where basis problems and partner disputes start.
• Firms reconcile draws to the allocation at year end. The excess either comes back to the partner as a true-up distribution, carries as a loan or overdraw against next year, or gets repaid, depending on the agreement.
• The Form 1065 instructions require Item L capital accounts on the tax-basis method: “Figure each partner’s capital account for the partnership’s tax year using the transactional approach … for the tax-basis method.” The IRS can see on the face of the K-1 whether distributions are running past basis. The bookkeeping guide covers the accounts that keep draws, guaranteed payments and capital separate.
• Client money is never a draw. The trust account is a separate discipline; see IOLTA trust accounting.

How does the pay structure affect retirement contributions?

They’re based on “earned income,” which IRC 401(c)(2)(A) defines as net earnings from self-employment “with regard to the deductions allowed by section 404” and “with regard to the deduction allowed to the taxpayer by section 164(f).” So the base is pay plus distributive share, less half the self-employment tax, less the contribution itself. Because the contribution cuts its own base, the 25% employer limit in IRC 404(a)(3) works out to 20% of net earnings after the half-tax deduction.

• The arithmetic is in Publication 560: the self-employed rate is the plan rate divided by one plus the plan rate, so 0.25 / 1.25 = 0.20. A partner with $400,000 of net earnings after the 164(f) deduction has an $80,000 profit-sharing base before the dollar cap.
• The dollar caps for 2026 per the IRS COLA table: $24,500 of elective deferrals, $8,000 catch-up at 50 and over, and $72,000 total annual additions under 415(c). For 2025: $23,500, $7,500 and $70,000. A SEP takes employer contributions only; a 401(k) adds the deferral and allows a Roth option.
• Guaranteed payment versus distributive share doesn’t change the ceiling, because both are in the base. What matters is the total and whether the plan’s contribution rate is uniform across partners and staff, which is where new comparability and cross-tested designs come in. Defined benefit and cash balance plans go well past $72,000 for older partners; the retirement plan guide covers the design choices.

Does the QBI deduction help a law firm partner?

Only at the low end. Law is a specified service trade or business under IRC 199A(d)(2), which points to the list in IRC 1202(e)(3)(A) (“health, law, engineering, architecture, accounting” and so on). For 2026 the 20% deduction is full below taxable income of $201,750 single or $403,500 joint, phases out over the next $75,000 or $150,000, and is gone at $276,750 and $553,500. For 2025 returns the threshold is $197,300 and $394,600, gone at $247,300 and $494,600.

• The figures are in Rev. Proc. 2025-32 section 4.26 and Rev. Proc. 2024-40 section 2.27. The wider 2026 range is the One Big Beautiful Bill Act’s change to 199A(d)(3)(A).
• A partner with $500,000 of K-1 income gets nothing. A junior partner or a solo at $180,000 of taxable income keeps a $36,000 deduction on $180,000 of QBI, and retirement contributions are the lever that keeps taxable income under the line.

What should I do next?

Pull your latest K-1 and check three things: Box 4a matches the guaranteed payment in the agreement, Box 1 matches your allocation percentage applied to the firm’s income after guaranteed payments, and Item L’s ending capital is a number you recognize. Then check that your estimates cover the self-employment tax, because the income-tax withholding you’re used to from associate years is gone. If the firm hasn’t looked at the plan design since the partnership grew, the 25%-becomes-20% rule and the 2026 caps are the place to start.

• Law firm entity structure: PC, PLLC, LLP and the S-corp election, the decision that turns partners into shareholder-employees
• Law firm retirement plans: Solo 401(k) and defined benefit, the largest deduction left once QBI is gone
• Law firm billing and collections, the revenue cycle that decides how much there is to allocate
• Law firm succession planning, buyouts and the IRC 736 rules when a partner retires
• Trust fund recovery penalty, the personal liability that attaches when the firm falls behind on staff payroll taxes
• Dental associate compensation and buy-in, the same 707(c) mechanics in another profession
