• Advising on the U.S. tax implications of international operations, including the interaction of U.S. and foreign tax rules to support efficient global tax strategies via transfer pricing and capital structures, among others
• Reviewing complex U.S. tax returns and related workpapers to ensure accuracy, completeness, and adherence to quality standards
• Collaborating with partners, managers, and teams across the network, demonstrating a desire to learn from others and proactively support colleagues working in Federal, state, and other tax disciplines
• Performing additional responsibilities as needed to support the firm’s tax function and global coordination efforts

You have the following technical skills and qualifications:  

• Bachelor's degree in Accounting  
• Minimum five to seven years of progressive tax consulting experience, preferably with at least three years focused on international taxation  
• Experience with a large accounting firm, law firm, or corporate tax department of a multinational company  
• CPA or JD/active law license required
• Excellent analytical, technical, and tax accounting/technology skills with proficiency in U.S. tax compliance and consulting  
• Strong computer expertise including knowledge of tax software and technology  
• Excellent verbal and written communication skills
• Can travel as needed 

The base salary range for this position is between $104,000 and $156,000. Placement within the pay range is at Grant Thornton’s discretion, and it is based on multiple factors, including but not limited to, job-related knowledge/skills, experience, business needs, progression within the role, geographic location, and internal equity. At Grant Thornton, compensation decisions are dependent upon the facts and circumstances of each position and candidate.
