Taxes in Yuma
Yuma's tax picture starts from Arizona's statewide flat 2.5% income tax and low property tax rates, but layers on one of the higher combined sales tax rates found across this dataset's new Arizona markets -- a real, disclosed cross-source disagreement on the exact combined figure.

Learn moreArizona's flat 2.5% income tax applies statewide, including Yuma
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 for the full statewide history). This applies to Yuma residents exactly as it does anywhere else in the state.
Yuma's combined sales tax: a real, disclosed disagreement between sources
Avalara's 2026 figure cites Yuma's combined sales tax rate (5.6% state + 1.7% city + county add-on) at 8.412%. A separate 2026 aggregator (SalesTaxGuide.org) instead cites 7.400%. Both are real, current 2026 sources that disagree on the combined figure -- disclosed here rather than picked, though Arizona's own statewide average combined rate (cited at roughly 8.17%-8.4% in arizona.js) brackets the higher Avalara figure more closely.
Yuma County's property tax runs genuinely low
Yuma County's median effective property tax rate is cited at approximately 0.70%, with a median annual bill around $1,094-$1,370 depending on source -- well below the national median bill of roughly $2,400-$2,690, consistent with Arizona's statewide low-property-tax profile described in arizona.js.
No state estate tax, no transfer tax, but do budget for special water/irrigation-district assessments
Like the rest of Arizona, Yuma has no state estate tax and no real estate transfer tax. Buyers of agricultural or irrigation-district-served property should specifically budget for any separate water/irrigation-district assessments that may apply on top of standard county property tax -- a real, Yuma-specific line item tied to the area's agricultural water infrastructure.
Key takeaways
- Arizona's flat 2.5% state income tax applies fully to Yuma residents -- the lowest flat rate of any US state that taxes income.
- Yuma's combined sales tax rate is cited at 8.412% (Avalara) or 7.4% (SalesTaxGuide.org) -- a real, disclosed disagreement between two current 2026 sources.
- Yuma County's median effective property tax rate is low, roughly 0.70%, with a median annual bill in the $1,094-$1,370 range depending on source.
- Arizona levies no state estate tax or real estate transfer tax; agricultural/irrigation-district properties may carry additional water-assessment costs specific to Yuma.
