Our Story
Focused on Tax Controversy & International Tax Compliance
Segal, Cohen & Landis was founded in Beverly Hills in 1991 with a single focus: representing taxpayers in disputes with the IRS and state tax agencies. That focus has never changed.
Over three decades, we have represented clients in every type of federal and California tax controversy — from routine correspondence audits to high-stakes Tax Court litigation to criminal tax defense. Our attorneys have appeared before IRS Revenue Officers, IRS Appeals Officers, IRS Criminal Investigation Special Agents, the U.S. Tax Court, and federal district courts.
Our international practice helps U.S. citizens living abroad, foreign nationals, and businesses with U.S. tax obligations. We handle FBAR and foreign account reporting, Form 3520, PFIC matters, offshore disclosure, and related IRS audits and penalties. Clients receive attorney-led guidance whether they are in the United States or overseas.
Our clients range from individuals with a single-year audit to large corporations with multi-year examinations to US citizens living abroad with years of unreported foreign accounts. Whether the amount at issue is $50,000 or $50 million, every client receives attorney-led representation from intake to resolution.

How We Work
Our Principles
Attorney-Led, Always
Every client at our firm is represented by a licensed attorney from the first consultation through final resolution. We do not assign cases to paralegals or non-attorney representatives.
Honesty Over Optimism
We tell clients the truth about their situation — the realistic outcomes, not the best-case scenario. Our reputation is built on honest counsel, not false promises.
Complete Confidentiality
Attorney-client privilege may protect confidential communications made to obtain legal advice, subject to applicable law and exceptions. It does not automatically protect every document or message sent to the firm. We have represented sensitive cases involving criminal investigation, offshore accounts, and high-profile individuals — all with complete discretion.
Resolution-Focused
We do not drag out engagements. Our goal is the fastest, most favorable resolution of your IRS or state tax problem — whether that means aggressive audit defense, a negotiated settlement, or litigation.
