Six-figure ZIP codes for Globe NorthWest

April 15, 2007

The chart below shows the percentage of individual tax returns, by zip code, that had an Adjusted Gross Income of $100,000 or more for tax year 2004. Adjusted Gross Income (AGI) includes income from all sources, such as salary and interest, minus deductions like IRA contributions. It does not include itemized deductions such as home mortgage interest.

Blank fields on the chart below mean there were either fewer than 10 or more than 75% of returns with an AGI of $100K or more in that zip code. The IRS believes that too few or too many such returns in one zip code could make the filers identifiable, so it withholds those numbers because of privacy concerns. Missing zip codes indicates no $100K filers. The list is sorted by zip code.
