Learn moreOregon's real progressive income tax, not a flat rate
Oregon runs four income tax brackets from 4.75% up to a real 9.9% top marginal rate, applying above $125,000 of taxable income for single filers -- among the highest top state income tax rates in the country, applying identically to Hillsboro residents as any other Oregon resident.
Washington County's property tax rate and Measure 50
Washington County's effective property tax rate carries a real, disclosed 0.84%-1.04% spread across sources (this record uses ~0.93% as a representative midpoint). As statewide, Measure 50 caps taxable assessed-value growth at generally 3%/year, so most Hillsboro homeowners pay tax on an assessed value below real market value.
Zero sales tax, genuinely complete
Oregon has zero state or local sales tax -- one of only five US states with none, a real, genuine simplification for day-to-day purchases that does not offset the real income tax burden documented above.

- Oregon's real progressive income tax reaches 9.9% at the top bracket (above $125,000 single-filer taxable income).
- Washington County's property tax rate runs a real, disclosed 0.84%-1.04% range, shaped by Measure 50's assessed-value cap.
