Top Tax Consulting Firms

Tax consulting is advisory work on how a business is taxed, rather than filing the return itself: entity structure, multi-state nexus and sales tax exposure, research and development credits, transfer pricing between related companies, and the tax side of an acquisition or a move abroad. A company brings in a tax consultant when it expands into new states or countries, receives a notice from a tax authority, or plans a transaction with large tax consequences.

Firms listed range from CPA practices with an advisory arm to boutiques that handle a single tax type, such as sales tax or information reporting. Match the firm's specialty to your issue, and confirm who on the team holds a CPA, enrolled agent or tax law credential.
