About Us: McCormick Tax was established in 2022 to serve clients worldwide – no matter their size – on any and all needs in the United States international tax context. Our clients range from multi-billion dollar business enterprises to cost-sensitive startups, high-net-worth individuals to those with lower net worths but discrete (and often complex) international tax needs. Our firm’s founder – a non-accountant international tax attorney - has previously served as a partner (exclusively focused on international tax work) at an AmLaw200 law firm, a boutique tax, trusts and estates law firm, and a tax-focused accounting firm, giving extensive experience both with every aspect of international tax rules and every type of client with international tax needs. Transitioning from a large firm to an independent practice has also enabled our firm’s practitioners to significantly reduce their hourly billable rates – creating efficiencies for our clients and allowing us to work with clients of all sizes.

Our firm covers every aspect of United States international tax, trusts, and estates rules; we also assist our clients on more domestic-oriented United States tax needs. We work directly with clients; we also serve as “outsourced international tax counsel” for accounting, law, and advisory firms around the world. In that role, we assist wherever beneficial with those firms’ client needs in the international tax context, allowing those firms to hang onto clients/continue to work with those clients rather than losing them to firms with internal international tax teams. Our firm’s independent status gives us enormous flexibility in how we structure representations, ensuring we can serve in optimal fashion for whatever client needs arise.
