With decades of courtroom experience, we develop strategic defenses for high-stakes tax disputes.
Tax Crime Defense
Our firm defends clients facing criminal tax investigations, grand jury subpoenas, and prosecution for tax evasion or fraud. We provide aggressive representation during IRS criminal probes, working to minimize penalties and protect clients' constitutional rights throughout the federal justice system.
Tax Audits
We guide clients through IRS and state tax audits, handling document requests, examiner communications, and settlement negotiations. Our approach focuses on minimizing liability while ensuring compliance with tax code requirements during both field and office audit processes.

We assist clients facing tax liens, levies, and wage garnishments by negotiating installment agreements, offers in compromise, and currently not collectible status. Our strategies aim to resolve collection issues while protecting clients' financial assets and business operations.
