International tax consulting for accounting firms

How Accounting Firms Can Use International Tax Expertise

Bring to your firm
an adviser with Big Four experience.

A long-standing client has asked about expanding or relocating overseas. You want your own firm to support them, but you are unsure about the international tax judgments involved.

For tax and accounting firms that do not need a full-time international tax specialist but want someone to consult when necessary, we offer an ongoing advisory service.

Our principal, tax accountant Kenji Yanagisawa, formerly of KPMG Tax Corporation, serves as your firm's international tax adviser.
Together, we build your capacity to respond to international tax inquiries while preserving your client relationships.

For Your Clients' Overseas Needs,
Help your firm answer your clients' questions.

The more local businesses an accounting firm supports, the more diverse its clients' needs become: starting international trade, forming an overseas company, or an owner relocating abroad. These situations may require analysis beyond routine domestic tax work.

Tax accountants have different specialties. Combining your understanding of your clients with our international tax experience broadens the advice you can provide. We welcome inquiries from firms seeking international tax support, including medium-sized and larger regional practices.
