Learn moreArizona's flat 2.5% income tax applies statewide, including Casa Grande
Arizona has taxed individual income at a single flat 2.5% rate since tax year 2023 -- the lowest flat rate of any state that taxes income at all (see arizona.js). This applies to Casa Grande residents exactly as it does anywhere else in the state.
Casa Grande's combined sales tax is the highest among this dataset's new Arizona markets
Casa Grande's minimum combined 2026 sales tax rate is 8.7% (5.6% state + 2.0% city + county add-on) -- higher than both Yuma (7.4%-8.412% depending on source) and Sierra Vista (8.55%) elsewhere in this dataset.
Property tax: a real, disclosed spread across multiple measures
Casa Grande's own median effective property tax rate is cited at 0.62%, above Arizona's statewide median of 0.51% (both from the same source). Pinal County-wide figures diverge more widely across sources: 0.84% (tax-rates.org methodology) versus 0.47% (a separate source) -- nearly double the difference, not reconciled this pass. Separately, Pinal County's own government presentation cites the county's PRIMARY rate at $3.3630 per $100 assessed valuation, the 4th-highest among Arizona counties, with combined rates (including all overlapping districts) reaching $3.4500 per $100 in some areas -- a different, narrower measure than an all-in effective rate.
ZIP-code-level bills vary substantially within Casa Grande
Property tax bills within Casa Grande range from roughly $406 in ZIP 85193 to $2,022 in ZIP 85194, primarily reflecting differing school-district and special-assessment-district levies -- a genuinely wide, real spread worth confirming for a specific address rather than assuming a single citywide figure applies.
