Case Study: American International Group (AIG) achieves automated international tax compliance and reduced risk with CSC Corptax

The Need for Automation and Risk Mitigation in International Compliance

American International Group (AIG), a global insurance organization operating in more than 100 countries, faced time-consuming, risky manual processes for Outside Basis (APB 23/ASC 740-30) data collection and calculation driven by disparate Excel spreadsheets. AIG struggled with manual updates, lack of workflow and security, duplicate data entry, and manual reconciliation to CSC Corptax Compliance, so they engaged Corptax Professional Services to deploy Corptax International Compliance and Corptax Provision workpapers to standardize and automate the process.

CSC Corptax implemented centralized, web-based data collection and calculation schedules, diagnostic and analytic reporting, and tightened security and workflow controls—enabling global simultaneous work, preparer/reviewer sign-offs, and clear audit trails for SOX compliance. As a result, CSC Corptax reduced duplicative Excel use and manual reconciliation, decreased man-hours and input errors, and delivered improved accuracy, ease of review and reporting (with automated international calculations and pre-population of source data), and AIG continues working with CSC Corptax Professional Services to expand automation.
