This whitepaper explores the PwC methodology for architecting and building a practical and flexible approach to FATCA compliance. It offers strategic insights on the implications of the changing information reporting requirements under FATCA and takes a deeper dive into some of the people, process and technology considerations to develop a FATCA compliance blueprint, both from an assessment and implementation perspective. We have applied this process to help a number of financial institutions address FATCA, and have refined the methodology and tools through lessons learned from the collective learning from those efforts.
