The largest American multinational companies parked an additional $206 billion of profits in offshore accounts last year, according to Bloomberg, bringing the total amount of profits stashed where U.S. tax officials can’t touch them up to about two trillion dollars.

The 307 companies that Bloomberg examined now hold a combined $1.95 trillion offshore, allowing them to avoid paying U.S. taxes on those earnings. The majority of the total is concentrated in just a few corporate hands. The largest 22 of those companies hold more offshore than the other 285 combined.

General Electric leads the pack, with $110 billion held offshore. Tech companies like Microsoft ($76.4 billion), Apple ($54.4 billion), IBM ($52.3 billion), and Google ($38.9 billion) also dominate, along with drug companies like Pfizer ($69 billion) and Merck ($57.1). The tech giants have drastically accelerated their offshore holdings in recent years, with Microsoft and Google more than doubling and Apple more than quadrupling offshore profit holdings from 2010 to 2013.

This propensity for profit-stashing among tech companies brought scrutiny from Congress last year, with committee reports and a Senate hearing where Apple CEO Tim Cook was called on to justify his firm’s tax behavior. That scrutiny exposed the complexities of how Apple pulls off its tax avoidance scheme through a set of Ireland-based subsidiary companies, but it also underscored that everything these companies are doing is legal. The current international corporate tax system encourages countries like Ireland, Luxembourg, and others to race each other to the bottom of the business tax rate barrel.
