The Richest ZIP Codes by Income per Tax Return

Source: IRS Statistics of Income, individual income tax ZIP code data, tax year 2022 (IRS ZIP code data). Method: Residential ZIP codes (Census 2020 ZCTAs) with 1,000 or more people living in households (200 or more households, at most 5 people a household, so campuses, bases and prisons are left out) that have their own page; for income and home value, a figure whose 90% margin is at most 25% of it (a value at a Census cap counts); ties share a rank; the 50 states, D.C. and Puerto Rico. ZIP codes where most residents are students are labeled. Adjusted gross income divided by the number of individual returns filed under the ZIP code, 2022; ZIP codes with fewer than 200 returns are left out. The IRS files a return under the address on it, which can be an office or a mailbox rather than the home, so ZIP codes with more than 1.5 returns per household (ACS) are left out too. It is an average: a few very large incomes lift it, so it orders the ZIP codes that the Census median leaves tied at its cap; the IRS publishes no median.
