The Law Office of Johan Deprez is a premier tax, business, and real estate law practice headquartered in Long Beach, California. Led by former IRS attorney and economics professor Johan Deprez, Ph.D., LL.M., the firm delivers sophisticated legal counsel in federal IRS tax resolution, California state tax controversy, international tax consulting, and strategic business planning.

Strategic Tax Law and Controversy Resolution in Long Beach

Complex tax laws demand experienced legal counsel. The Law Office of Johan Deprez, also known as Deprez Tax Law, provides strategic guidance for individuals and businesses across Long Beach, Los Angeles County, Orange County, and throughout California. Established by Johan Deprez, a seasoned tax attorney licensed with the State Bar of California since 2001, the firm represents clients facing intricate state, federal, and cross-border tax challenges.

Advanced Academic and Government Tax Experience

Johan Deprez brings rare legal and economic expertise to tax controversies. He holds a Ph.D. in economics from Rutgers University, a Juris Doctor from Loyola Law School in Los Angeles where he was Articles Editor of the Loyola of Los Angeles Law Review, and an advanced Master of Laws in taxation. Dr. Deprez served for more than eight years with the Office of Chief Counsel and Competent Authority of the Internal Revenue Service, alongside work at major corporate firms and accounting practices. This firsthand insight into tax agency procedures enables him to construct robust defense strategies for clients confronting aggressive audits.

Federal IRS and California State Tax Resolution

Dealing with tax collection agencies can disrupt personal finances and commercial operations. As skilled tax lawyers and irs dispute lawyers, the firm represents clients in sensitive disputes before the Internal Revenue Service, the California Franchise Tax Board, the California Department of Tax and Fee Administration, and the Employment Development Department.

Practice areas include:

  • IRS audit defense: Managing examinations, administrative appeals, and penalty abatement requests.
  • Tax relief solutions: Negotiating installment agreements, offers in compromise, and payment plans.
  • State tax controversy: Resolving California income, sales, and payroll tax disputes.
  • Property tax resolution: Handling county property tax assessment appeals.

When taxing authorities issue notices of deficiency, bank levies, or liens, taxpayers who urgently need a lawyer can rely on the firm to intervene promptly and negotiate viable resolutions.

International Taxation and Cross-Border Planning

With global commerce and multinational families becoming more common, international tax compliance has grown increasingly complex. The firm provides specialized international tax consulting, including transfer pricing analysis, foreign bank account reporting compliance, cross-border estate planning, and inbound or outbound investment structuring. Dr. Deprez helps clients navigate double taxation treaties and avoid severe statutory penalties.

Comprehensive Business Formation and Commercial Counsel

In addition to tax controversies, the firm acts as trusted corporate counsel. As experienced business formation lawyers and contract lawyers, the legal team assists clients with entity structuring, drafting shareholder agreements, reviewing commercial contracts, and handling corporate restructuring. The firm aligns business transactions with tax efficiency to minimize future liabilities.
