Welcome CIATData
The Inter-American Center of Tax Administrations (CIAT), aware of the need of the tax administrations of member countries and associate-member countries to access information in standard formats that facilitate analysis and allow easy comparison, presents the new CIATData service.
In CIATData you will find basic information about CIAT member countries and associate-member countries, such as a brief description of their tax system, the features of their tax administration and the recent evolution of their tax revenue. Likewise, the service enables querying Information Exchange Agreements and/or Double Taxation Agreements subscribed, historical comparisons of the rates from their main taxes and different tax indicators.
In the first phase, CIATData shall deliver more information for the Latin American area, but shall soon complete the information for all CIAT member and associate-member countries, to become one of the most complete free databases on the subject.
Additionally, we have been working to expeditiously update information on tax legislation. To such end, we rely on the usual invaluable support of all our member and associate-member countries
