The GATCA app is an essential tool for responsible officers, relationship managers, and financial services professionals responsible for ensuring tax compliance.

If your firm is affected by detection and deterrence of tax evasion regulations such as FATCA, the OECD’s CRS and Automatic Exchange of Information, the US QI and NQI regulations, or Base Erosion and Profit Shifting regulations (BEPS), then the GATCA app is a vital tool for your compliance armoury.

We have brought together documents from a number of different public domain sources and added value through expert curation - giving the documents standard file names and publication dates, arranging them into folders according to jurisdiction, and providing practical tools to support your compliance programme.
