IRS Statistics of Income tabulations for every US ZIP code (tax year 2022): tax returns, adjusted gross income, average AGI per return, wages, capital gains, EITC, charitable giving and more, broken out by six AGI brackets. 166,131 state×ZIP×bracket cells across 27,588 ZIPs — $14.5T total AGI. Cell-level aggregates with IRS suppression applied — zero PII (no taxpayer-level data). Search any ZIP and pull its income breakdown; the average-AGI-per-return figure is a strong local-income proxy that joins to the hub's other ZIP/county-keyed datasets (FHFA HPI, RMA crop insurance). Canonical /income-by-zip/{zip} page per ZIP. From IRS SOI bulk CSV (key-free).
