Global Withholding Tax Services

Our Approach
Ryan’s Global Withholding Tax Review delivers substantial tax savings and refund opportunities. Ryan international tax specialists employ proven methodologies and state-of-the-art technology to conduct a detailed, end-to-end global review of your withholding tax. Theyߴll identify and reclaim overpaid withholding tax, including those associated with third-party and intercompany transactions.

International Attribute Calculations

Our Approach
Ryan’s international tax services team calculates your international tax attributes, including Earnings and Profits (E&P) analyses, foreign tax pools, basis in non-U.S. stocks or assets, and currency-related analyses (e.g., Sections 987, 988, etc.) The benefits for your global organization are vast: increased foreign tax utilization, audit-ready documentation of deemed paid foreign tax credits, and reduced Subpart F inclusions and effective tax rates for financial statement purposes.

Frequently Asked Questions

  • As multinational companies expand into new jurisdictions, their risks in international tax compliance expand, too. These include: 
    • Compliance: Tax laws, reporting requirements, key dates, and more differ greatly from country to country. As companies expand into new jurisdictions, they take on a greater risk for compliance concerns and associated penalties. 
    • Regulatory changes: Keeping up with ever-changing tax laws becomes increasingly difficult as companies expand into more jurisdictions. 
    • Documentation requirements: More jurisdictions means more documentation, each with their own precise requirements. Failure to provide the correct information puts companies at risk of compliance concerns. 
    • Double taxation: Navigating tax laws surrounding double taxation can be complex. Companies may find it increasingly challenging to avoid paying tax on the same income twice. 
    Ryan manages these challenges through proactive monitoring and audit-ready documentation. Whenever possible, our tax professionals use automation to reduce the risk of manual errors.

    • Treaty benefits
