President Lula signed Lei 15.504 on 15 September, creating Redata, the data-centre tax regime Brazil's Senate passed on 1 September1. The law suspends import duty, two federal revenue contributions and the industrial products tax on qualifying cloud and artificial intelligence (AI) builds. The Treasury estimates the cost at about 5.2bn reais in 2026, falling to about 1bn reais a year after.
The signed text carries no veto message. Its water condition sits in Article 11-B, item IV, which the law inserts into Brazil's 2005 tax statute, Lei 11.196: 0.05 litres per kWh, checked every year2. The Senate's cap now binds every Redata claimant.
Because the limit rides on the tax break rather than on a planning consent, it reaches only developers who claim the suspensions, and it stays with them for as long as they keep the benefit. In the same week, Brazil's grid authorities published a connection authorisation for an AI campus in Rio Grande do Sul planned by Scala Data Centers, the kind of build the regime is written for.
