Frequently Asked Questions
Are IOLTA interest earnings taxable income for attorneys?
No. IOLTA (Interest on Lawyer Trust Accounts) interest is paid directly to the state IOLTA program for legal aid funding β not to the attorney or the client. Because the interest is never available to the attorney, it is not reportable as income on the attorney's tax return. Attorneys should never include IOLTA interest on their tax return. The financial institution reports IOLTA interest to the state bar program, not to the individual attorney.
Are client cost advances deductible by attorneys?
Generally, client cost advances (court filing fees, expert witness fees, deposition costs, etc.) are treated as loans to the client β not deductible expenses when paid. They become deductible only when the case resolves and the costs are either collected from the client or written off as uncollectible. Cash-basis attorneys cannot deduct these until they are actually written off. This differs from contingency fee cases where the attorney may advance significant costs that remain in limbo until verdict or settlement.
How does cash basis vs. accrual basis affect attorney tax planning?
Most attorneys use cash basis accounting, meaning income is recognized when received and expenses are deductible when paid. This creates planning opportunities: defer billing to push income into next year, or accelerate payment of deductible expenses before year-end. Accrual basis requires recording income when earned regardless of receipt. For contingency fee attorneys, this distinction is critical β under cash basis, no income is recognized until the fee is received, even for cases that have settled but payment hasn't arrived.
Should lawyers use S-Corp to reduce SE tax?
S-Corp election can significantly reduce self-employment tax for attorneys earning more than $60,000β$80,000 in net profit. An attorney paying themselves a $120,000 reasonable salary through an S-Corp and taking $100,000 in distributions saves approximately $15,300 in FICA on the distribution portion. However, some states prohibit law firm S-Corps or have special rules for professional corporations. Additionally, the "reasonable salary" standard is enforced more strictly for attorneys than some other professions. Consult a tax attorney familiar with your state's professional corporation rules.
How are contingency fees taxed when received over multiple years?
Contingency fees are taxed on receipt under the cash method β the year you receive the fee is the year it is taxable income. If a settlement is paid over multiple years (structured settlement), you report each payment in the year received. For large contingency fees, the "bunching" of income in one year can push you into higher brackets. Strategies include: installment arrangements with the defendant (structured fee), creating a deferred compensation arrangement through the firm, or investing in retirement accounts to reduce the taxable amount in high-fee years.
