For those who don't know, or maybe just don't remember, the LuxLeaks – as they became known – was a six-month investigation.
ICIJ worked with more than 80 reporters in 26 countries on the project that analyzed nearly 28,000 pages of leaked documents.
The documents detailed special tax deals granted by the Luxembourg government to some of the world's largest corporations, including Disney and Ikea. In total, the investigation revealed nearly 340 companies that were using secret Luxembourg deals to slash their global tax bills. These deals were managed by PwC, Ernst & Young, Deloitte and KPMG.
The LuxLeaks investigation prompted widespread condemnation of the practice, but that didn't stop Luxembourg and a year later the country had made another 172 "sweetheart deals."
This video below explains how the huge companies behind everyday brand names, products and services slashed their tax bills.
