The Washington Post did a lot of digging into where Bannon lived before he started working with Trump (short answer: he had places in Calif. and Florida and spent a lot of time at the Breitbart offices in D.C.), and they found a lease he signed in 2013 where he disclosed his income.

$270,000 as executive chairman of Arc Entertainment (a film distribution company)
