Where are America’s richest zip codes? Bloomberg reports that you probably won’t be surprised to learn that many of these locations are in California and the New York City area. However, states like Florida and Wyoming, both with favorable tax climates, have also made the list. The honor of having the richest zip code in America goes to Fisher Island (33109), located just off the coast of Miami, Florida. This 216-acre island has an average income of $2.5 million and is the only zip code in Bloomberg’s analysis where over half of all tax returns had an income of over $200k. To produce their list, Bloomberg evaluated IRS data for zip codes with more than 200 tax returns as of the 2015 filing season, and with 500 residential households according to the latest Census. More than 22k zip codes met this criteria.
