What is Standard Audit File for Tax (SAF-T)?

SAF-T, introduced by OECD, is a file containing reliable accounting data exported from an accounting system for a specific time period. It has become a standard audit application in many OECD countries. The goal is to identify and eradicate the non-compliance in tax reporting. SAF-T has brought significant benefits to governments and taxpayers. Reduced costs and audit durations, and increased effectiveness are some of them. SAF-T is easily readable thanks to its standardized layout and format, and extensible according to need.
