Vacovec, Mayotte & Singer

What Vacovec, Mayotte & Singer does

Vacovec, Mayotte & Singer LLP (VMS) is a Newton, Massachusetts-based tax law firm founded in 1980 by Kenneth J. Vacovec. The firm specializes in complex tax planning, structuring, and compliance, with particular depth in international and cross-border tax matters involving U.S. and foreign jurisdictions. Its practice covers four areas: International & Domestic Taxation (including tax return preparation, tax planning, and representation before the IRS, Massachusetts DOR, and U.S. Tax Court), International Tax Services, Business Planning (entity formation, partnerships, and international business structuring), and Estates, Trusts & Probate (estate planning, probate, and closely held business transfer). Clients include individuals, businesses, estates, trusts, high net worth individuals with cross-border exposure, foreign nationals, and families with closely held businesses.

The firm operates with approximately 10 attorneys, including founding partner Kenneth J. Vacovec (AV-rated by Martindale-Hubbell, former President of the Massachusetts Bar Association), partners Kenneth H. Light and Tonya S. James, and several associates with LL.M credentials in taxation. Service delivery is direct and engagement-based, with attorneys consulting on a transaction-by-transaction basis within broader income, estate, and business tax planning frameworks. The firm's technology footprint is limited to standard legal practice tools—ShareFile for secure document exchange and SafeSend ONE for tax document automation—plus a global network of overseas lawyers, accountants, and financial service providers that enables cross-border service delivery.

VMS generates revenue through professional services billing for tax advisory, compliance, and representation work. Pricing is not publicly disclosed and is presumably quote- and hourly-rate based depending on engagement scope. Marketing is primarily organic: a website with practice-area content and downloadable resources, a LinkedIn presence, periodic newsletters, and attorney speaking engagements at organizations such as the Boston Tax Institute, Massachusetts Bar Association, and International Fiscal Association. The firm operates from a single headquarters in Newton, MA, serving clients throughout the United States and internationally, with no disclosed acquisitions, expansion into new offices, or major structural changes in the available data.
