Tax Guide for Attorneys and Legal Professionals

Attorneys who are law firm partners, solo practitioners, or of counsel relationships receive income taxed very differently from associates who receive a W-2. Partners in law firms typically receive a Schedule K-1 showing their share of partnership income, while solo practitioners file Schedule C. Both face self-employment tax and need to plan carefully.

Partnership Income and K-1s

Law firm partners receive a Schedule K-1 from the partnership at tax time, typically in March or early April (often causing a need to extend). The K-1 shows their distributive share of partnership income, which is subject to self-employment tax. Partners also need to make quarterly estimated tax payments, since no withholding occurs from partner draws.

Solo Practitioners and Schedule C

Solo attorneys file Schedule C and can deduct substantial business expenses: office rent, malpractice insurance, bar dues and license fees, CLE courses, legal research subscriptions (Westlaw, LexisNexis), case management software, legal library books, expert witness fees that clients reimburse, and business-related travel.

Client Advances and Trust Accounts

Money held in client trust (IOLTA) accounts is not your income until you've earned it. Be careful not to commingle or treat trust account funds as your own — this is both an ethical violation and a potential tax mistake. Money becomes income when it's transferred out of trust to your operating account.

Contingency Fee Income

If you work on contingency, income recognition can be complex. Generally, you recognize income when you actually receive payment, but very large contingency fees may warrant consulting a tax professional about any deferral or installment structures.

Qualified Business Income Deduction

Law is a Specified Service Trade or Business under the QBI deduction rules, which means the 20% deduction phases out at higher income levels. Above the threshold, attorneys may not be eligible for the full QBI deduction. This is one reason tax planning is especially important for high-income attorneys.

Retirement Planning

Solo attorneys and partners can contribute significantly to retirement accounts — a Solo 401(k) or SEP-IRA can shelter a large portion of income from taxation each year. Maximizing retirement contributions is often the most powerful tax reduction strategy available to legal professionals.
