Configuring a VAT Regime for a country in Oracle E-Business Tax (or EBTax) in 12 easy steps is a relatively straightforward exercise that can usually take about half a day to configure.
Oracle E-Business Tax surfaced with the advent of R12 back in January of 2007. For the most part Tax always seems to take a back seat to all of the exciting reporting projects and dashboards even though tax done wrong loses money and creates unnecessary risk. Part of the story with EBTax not getting leveraged had to do with those persons who do Oracle Consulting for a living. Tax is for experts. Understanding Tax should not be left to PL/SQL converts since understanding Indirect Tax and Laws is a tad more difficult and nuanced than the old-fashioned AP or AR invoicing and payments or receipts.
Here are the 12 Steps to doing a VAT Regime. The software solution is pretty intuitive but Tax Law certainly is not and the laws and the understanding of laws is where things go sideways for many projects.
