“The primary subject of Law No. 120 of 2013 had nothing to do with income taxes, but two articles had been inserted into it to amend the tax code. The meaning was clear: Those who pay taxes in Panama must in the future, pay based on their worldwide income instead of just their Panamanian-sourced income. This law was passed in darkness. There had been no public debate, yet it was signed into law by President Ricardo Martinelli on 30th December. The episode in Panama is a bellwether. Increasingly, we shall see governments passing legislation, issuing edicts, and taking action unannounced, as they seek to take a last squeeze of the lemon, prior to the collapse.”
