Best Law Firms BadgeJeffer Mangels Butler & Mitchell LLP has one of the leading tax practices in California, within a full service law firm. The Group's attorneys focus primarily on transactional matters. In addition to serving individuals, families, and closely-held businesses, our clients include organizations ranging from start-ups to Fortune 500 companies. When tax controversies arise, our clients rely on us to resolve the matter efficiently and effectively.

At JMBM, tax and business counseling blend seamlessly. Our tax lawyers understand business concerns, and work closely with colleagues in the firm’s corporate and real estate groups to ensure the tax efficiency of organizational and transactional decisions.


Tax consequences are often an extremely important component of many deals. We frequently play the lead role in negotiating and drafting transactional documents, partnership agreements, LLC operating agreements, shareholder agreements and buy-sell agreements. We also advise on the tax consequences of mergers, acquisitions and dispositions.

Choice of Entity

The choice of the appropriate entity for conducting a business is often made in light of the resulting tax consequences. We advise whether a business should operate as a partnership, limited liability company or corporation.

Real Estate

Ownership of real estate is a significant component of wealth for many of our clients. We advise them on the tax aspects of structuring the acquisition, holding and disposing real property, including choice of entity property tax reassessment, 1031 exchanges and special allocations and carried interests.

Executive Compensation

We assist clients in designing and implementing executive compensation programs such as nonqualified deferred compensation arrangements and stock options.

International Tax

We provide international tax planning, typically in entertainment, real estate and technology ventures. We advise U.S. and foreign clients on ways to minimize taxes on income, the best structure in which to conduct international businesses, how to obtain U.S. tax credits for local taxes paid in a foreign jurisdiction and how to reduce or avoid U.S. federal and state withholding and employment taxes on income earned by foreigners providing personal services to U.S. entities.

State and Local Tax

We assist our clients with all state personal and corporate income tax issues, real property tax assessments, state sales and use taxes and employment taxes.

Tax Controversy

We frequently appear before the Internal Revenue Service, the Franchise Tax Board, the State Board of Equalization and the Employment Development Department in connection with audits of federal and state income taxes, state sales and use taxes, and employment taxes.
