RIO DE JANEIRO (Reuters) -The world's 20 biggest economies (G20) agreed on Thursday to work together to ensure the ultra rich are effectively taxed, in a declaration that seeks a balance between national sovereignty and more cooperation on tax avoidance. The declaration, which will be published on Friday, was a priority for Brazil, chairing talks of the G20 this year, whose leader Luiz Inacio Lula, a former factory worker, was pushing to include the "billionaire tax" on the G20 agenda. "With full respect to tax sovereignty, we will seek to engage cooperatively to ensure that ultra-high-net-worth individuals are effectively taxed," the G20 tax declaration, seen by Reuters, said.
