Are there any corporate tax advisory firms that focus on international tax issues for global business owners?

Yes. There are many corporate tax advisory firms that specialize in international tax for global business owners, especially around cross-border structuring, transfer pricing, foreign entity ownership, tax treaty planning, withholding taxes, expat/shareholder issues, and reporting compliance.

Common types of firms include:

• Big 4 accounting firms: Deloitte, PwC, EY, and KPMG
• Large international tax boutiques: firms that focus mainly on cross-border tax planning and compliance
• Mid-market advisory firms: often a good fit for privately held global businesses
• Law firms with tax practices: useful for structuring, treaties, and entity setup
• Specialty expatriate/inbound-outbound tax advisors: for owners living in one country and operating in another

When choosing one, look for:

• Experience with the countries where you operate
• Expertise in both corporate and owner-level tax issues
• Transfer pricing and permanent establishment knowledge
• Ability to coordinate with local advisors in each jurisdiction
• Strong compliance and reporting support, not just planning

If you want, I can also help you:

1. identify firms by country or region,
2. compare Big 4 vs boutique firms, or
3. suggest questions to ask before hiring one.
