Strategic Defense in IRS Audits and Tax Controversy

Facing a comprehensive tax audit or criminal tax examination requires sophisticated representation to protect your freedom and assets. As experienced tax lawyers and IRS dispute lawyers, the practice guides taxpayers through complex regulatory challenges:

  • IRS and State Audit Representation: Defending individuals and corporate entities during challenging audits by the IRS, FTB, and EDD regarding business expenses and deductions.

  • Offer in Compromise (OIC) and Penalty Abatement: Negotiating federal and state tax settlements, partial payment installment agreements, and substantial penalty abatements.
  • Tax Court Litigation: Filing petitions and defending taxpayer rights in the United States Tax Court to challenge improper deficiency assessments.
  • Ponzi Scheme Theft Loss Deductions: Securing tax relief and safe harbor write-offs for investors harmed by financial fraud under Internal Revenue Code Section 165.

International Taxation, FBAR Compliance, and OFAC Sanctions

Managing overseas financial accounts and cross-border inheritances places individuals squarely under intense federal scrutiny. Functioning as premier financial and IP lawyers alongside skilled contract lawyers, attorney Fallahi specializes in global compliance matters:

  • FBAR and FATCA Compliance: Advising clients on Report of Foreign Bank and Financial Accounts (FinCEN Form 114) and foreign asset disclosure mandates.
  • IRS Voluntary Disclosure Practice (VDP): Guiding taxpayers through formal voluntary disclosures to rectify unfiled returns and avoid criminal prosecution.
  • OFAC Sanctions Legal Opinions: Assisting Iranian American clients and multinational families with U.S. Treasury Office of Foreign Assets Control licensing for legal fund transfers.
  • Cryptocurrency and Digital Asset Taxation: Formulating compliance strategies for virtual currencies, DeFi yields, staking income, and blockchain asset reporting.

Mr. Fallahi structures corporations, LLCs, and medical and dental professional practices to achieve optimal tax efficiency while insulating owners from liability. Furthermore, he drafts revocable living trusts and comprehensive estate plans designed to minimize estate taxes and bypass statutory California probate.
