As a Tax Associate at PWC, I've had the opportunity to work on several international tax planning projects for our clients. We extensively used tools like Taxware and Bloomberg BNA for tax planning and optimization, which gave us insights about various tax regulations, rules, and procedures in different countries.
One of the significant projects I was involved in was creating a tax strategy for a client with operations spanning across the US, UK, and Germany. We utilized Bloomberg's BNA Tax Management Portfolios to understand the tax landscape and develop an optimal strategy that minimized the client's tax liabilities while ensuring compliance with all jurisdictions. Utilizing these tools, we managed to achieve a 15% reduction in overall tax liabilities for the client, showcasing the importance and effectiveness of using tax planning tools.
