Attorney Tax Deductions: What Big Law Associates and Partners Can Write Off in 2026

The Tax Cuts and Jobs Act permanently changed what attorneys can deduct — and the answer depends almost entirely on whether you're a W-2 associate or a K-1 equity partner. The gap is substantial. Here's exactly what changed, what's still available, and why making partner restructures your entire deduction landscape.

The TCJA shift: what W-2 associates lost (and it's permanent)

Before 2018, W-2 employees could deduct unreimbursed business expenses — bar dues, CLE, professional subscriptions, home office costs — as miscellaneous itemized deductions subject to a 2% of AGI floor under §67. For a Big Law associate earning $300K, the floor was $6,000; anything above it was deductible.

TCJA §11045 eliminated the §67 miscellaneous itemized deduction floor entirely. For tax year 2026, W-2 associates have no path to deduct:

• State bar dues and annual registration fees
• CLE attendance costs and licensing fees
• Westlaw, Lexis, or research subscriptions paid personally
• Home office expenses (even if you work remotely)
• Professional association memberships (ABA, specialty bars)
• Investment advisory fees
• Tax preparation fees

This is a hard line. No workaround exists for W-2 employees. If your firm reimburses these expenses, that's a different result — reimbursement is not income to you, and the firm deducts the costs. But out-of-pocket expenses you pay personally are gone as deductions for associates under current law.

What W-2 Big Law associates can still deduct

The deductions that survived for W-2 employees are all above-the-line (reducing adjusted gross income directly rather than as itemized deductions):

For W-2 associates, 401(k) and HSA maximization are the primary tax levers. A first-year associate in New York who maxes both ($24,500 + $4,400 = $28,900 in above-the-line reductions) saves approximately $11,000–$12,000 in combined federal and state income taxes. See our Big Law 401(k) guide and backdoor Roth IRA guide for the full savings stack.

Making equity partner: the deduction landscape resets

When you cross from W-2 associate to equity partner — receiving a Schedule K-1 rather than a W-2 — you become self-employed for federal tax purposes. That status restores a substantial set of deductions that were unavailable as an employee, but requires claiming them correctly. There are two pathways:

1. Partnership-level deductions: Expenses paid by the firm and deducted by the partnership flow through to reduce each partner's distributive share. Most large firms handle bar dues, malpractice insurance, and professional subscriptions at the firm level — check your firm's expense reimbursement policy first.
2. Unreimbursed partnership expenses (UPE): Costs you pay personally that the partnership requires but does not reimburse. Deducted on Schedule E, Part II, line 28, directly against your K-1 partnership income. This is the equity partner's equivalent of the §67 employee business expense deduction that associates lost.

Unreimbursed partnership expenses (UPE): the key deduction for equity partners

If you pay ordinary and necessary business expenses that the partnership requires but does not reimburse, you can deduct them as UPE — offsetting your K-1 partnership income directly on Schedule E. No 2% floor. No itemized deduction limitation. UPE reduces your taxable income and does not increase your self-employment income (so it doesn't generate additional SE tax).

§162(l) self-employed health insurance deduction

Equity partners who pay their own health insurance premiums can deduct 100% of those costs as an above-the-line deduction under §162(l). This is one of the highest-value deductions available to partners. The key rules:

• Deduction is limited to your net K-1 partnership income — you cannot create a loss with this deduction
• Includes medical, dental, and qualifying long-term care premiums
• NOT available in any month you were eligible to participate in an employer-sponsored plan, including through a spouse's employer
• At the 37% marginal federal rate, every $1,000 in premiums deducted saves $370 in federal income tax — plus applicable state income tax

A partner paying $28,000/year in family health insurance premiums gets a $28,000 above-the-line deduction — worth roughly $10,400 in federal tax at the 37% bracket. That partially offsets the SE tax cost of partnership. See our partner health insurance guide for how AmLaw firms structure coverage as partners transition from W-2 benefits.

SE tax deduction: 50% above-the-line

Equity partners pay the full self-employment tax — both the employee and employer share of FICA — on their K-1 ordinary income. Half of SE tax paid is deductible as an above-the-line adjustment under §164(f).³

On $600K of K-1 ordinary income, the SE tax deduction is approximately $27,000–$28,000, saving roughly $10,000 in federal income tax at the 37% bracket. This doesn't eliminate the SE tax cost — you've already paid it — but it reduces your income tax base. See our equity partner tax guide for the full SE tax calculation.

Retirement contributions: the equity partner advantage

Equity partners can shelter significantly more income than W-2 associates through retirement contributions. The 2026 §415(c) combined limit is $72,000.¹

• If the firm has a qualified 401(k) plan: Contribute the maximum employee deferral ($24,500) plus any employer profit-sharing contribution, subject to the $72,000 combined ceiling. At large AmLaw firms, total 401(k) funding at the partner level often reaches the $72,000 cap.
• SEP-IRA (for a separate personal service entity): Some partners form their own professional corporation to receive certain income, enabling a SEP-IRA contribution of up to the §415(c) limit. Requires separate entity setup and business justification.
• Cash balance plan layered on 401(k): At firms with cash balance plans, partners can shelter $100K–$250K+ annually depending on age — far exceeding the §415(c) limit. At a 37% marginal rate, a $200K cash balance contribution is worth $74,000 in current-year federal tax savings. See our cash balance plan guide.
• NQDC elections: Deferring income into a law firm non-qualified deferred compensation plan reduces the current K-1, avoiding both income and SE tax on deferred amounts now. Irrevocable elections are due December 15 for the following year. See our NQDC optimizer for the lifetime tax math.

Home office deduction for equity partners and remote lawyers

Partners who maintain a home office exclusively for firm-related work can claim the home office deduction under §280A(c)(1). The exclusive-use test is strict — the IRS does not permit deductions for rooms with mixed personal use.⁴

Two methods:

• Simplified method: $5 per square foot of dedicated office space, maximum 300 square feet = up to $1,500/year. Easy to calculate, no depreciation recapture on home sale.
• Actual expense method: Allocate actual home expenses (mortgage interest, rent, utilities, repairs, depreciation) by the percentage of square footage used for the office. For a $2M home with a 10% dedicated office allocation, the actual method can yield $20,000–$35,000+ annually including depreciation — far more valuable than the simplified method, but subject to depreciation recapture when you sell.

For partners working primarily from home (common post-2020), the actual method is often worthwhile. Run the numbers with your CPA if your dedicated office space is meaningful.

Business meals and travel

Law firm equity partners — and the partnership itself at the firm level — can deduct ordinary and necessary business expenses under §162:

• Business meals: 50% deductible under §274(n) when there is a clear business purpose and a client, referral source, or colleague present. Meals without a documented business purpose are not deductible.
• Business travel: 100% deductible when the primary purpose is business — airfare, hotel, and ground transportation to client sites, depositions, court appearances, and firm retreats.
• Entertainment: TCJA eliminated the entertainment deduction entirely. Client sporting events, concerts, and other entertainment are not deductible regardless of business purpose. Client dinners are 50% deductible; tickets to a Knicks suite are zero.

SALT deduction and the PTE workaround

The state and local tax (SALT) deduction for individual taxpayers has been capped under TCJA — the 2026 status should be confirmed with your CPA given ongoing legislative activity. At Big Law income levels in New York, California, or Illinois, state income taxes alone can far exceed any individual SALT cap, making the limitation acutely painful regardless of the specific ceiling.

Deduction comparison: associate vs. equity partner

Why deductions matter for the partnership decision

The deduction landscape is one underappreciated component of the associate-to-partner financial transition. Making equity partner doesn't just increase your income — it restructures your tax profile. The combination of §162 UPE deductions, §162(l) health insurance, retirement plan expansion, home office, and the PTET workaround can significantly reduce your effective rate on incremental income — partially offsetting the SE tax cost that partnership adds.

This doesn't make partnership "cheaper" in absolute terms. SE tax alone adds 3–4% to your effective rate on the first $184,500 of K-1 income. But it means a financially sophisticated equity partner can capture deductions that an associate with identical gross income cannot — and that the after-tax math of partnership is more favorable than a simple bracket comparison suggests.
