About Blais HALPERT TAX PARTNERS LLP:

Blais Halpert Tax Partners LLP is a transactional tax boutique focused on tax-sensitive structuring and implementation of high-value business transactions, including mergers and acquisitions, growth company startup and financing, private equity and venture capital investments, fund formations, real estate, and executive compensation arrangements. We help structure, negotiate, and draft to ensure the most tax-efficient achievement of our clients’ objectives.

We are fluent in the most important business entities, from C and S corporations to partnerships and LLCs to investment and grantor trusts. Much of our work is international in nature, advising on cross-border acquisitions, sales, and investments.

A cornerstone of our practice is serving as tax co-counsel to corporate lawyers and non-U.S. law firms who need top-tier U.S. tax support for their clients’ business transactions. We regard our co-counsel as our partners in delivering seamless, practical, efficient, and valuable service to clients. Our practice is nationwide and we work regularly wherever one finds fast-growing and middle market companies, including Boston, New York, Miami, Chicago, Austin, Denver/Boulder, and Silicon Valley. In our international practice, our clients are from, or expanding to, diverse locales, including Toronto, London, Moscow, Mumbai, Hong Kong, and Melbourne.

We offer a unique value proposition in providing sophisticated transactional tax advice to the middle market, which is underserved by many of the “specialty” law areas. We bring expertise, efficiency, an understanding of how tax advice integrates with non-tax legal and business objectives, and most of all, the ability to communicate tax law to non-tax lawyers and business clients.
