JoAnna Mendoza’s tax-hike record and campaign conduct are drawing sharp scrutiny as she campaigns for Arizona’s Sixth District seat.
JoAnna Mendoza, a wealthy Democrat running in AZ-06, has a record of pushing steep tax increases while promoting far-left priorities that include defunding law enforcement, loosening border enforcement, and legalizing prostitution to support vulnerable groups. Voters in the Sixth District are hearing a clash between her vision and more conservative alternatives that emphasize tax relief and economic stability.
Records show Mendoza worked for the Arizona Center for Economic Progress, an organization with ties to national progressive donors, and she criticized Arizona’s flat tax in 2023. She said, “We don’t have to tilt the system toward the wealthy. We can ensure everyone pays their fair share,” a line that signals her preference for higher rates on higher earners.
Under her influence, the Arizona Center pushed to repeal the 2.5 percent flat tax and to replace it with a graduated rate structure while banning new tax credits for individuals and corporations. Mendoza also supported the 2020 initiative that backed an 8 percent state tax on incomes above $250,000 through Proposition 208, signaling a willingness to dramatically raise rates on high earners.
The proposed graduated structure would use four brackets instead of the current single rate. Income up to about $27,272 would be taxed at 2.59 percent, income from roughly $27,273 to $54,544 at 3.34 percent, income from about $54,545 to $163,632 at 4.17 percent, and income above roughly $163,632 at 4.5 percent, producing meaningful increases for many taxpayers.
The impact is larger when you factor in the existing Proposition 208 surcharge: a 3.5 percent add-on for income over $250,000 for single filers or $500,000 for joint filers, which effectively adds roughly $3,500 for every $100,000 above those thresholds. Analysts estimate that moving from the 2.5 percent flat tax to Mendoza’s plan would translate into more than a 30 percent boost in tax bills for the median household in AZ-06, where median income sits just under $80,000.
Critics also point to Mendoza’s personal finances and campaign behavior as part of the story. She is a millionaire who has taken tens of thousands in campaign disbursements for herself, even though federal election rules limit candidate salaries in narrow circumstances. Republican operatives argue that the combination of self-payments and calls to raise taxes on working families raises serious ethical questions and could amount to wrongdoing.
“It’s sick that Mendoza is embezzling from her campaign while advocating raising taxes 30% or more on working and middle-class Arizona families,” RNC Spokesman Nick Poche told Townhall. “With JoAnna Mendoza, the radical left gets whatever they want, and Arizonans get to pay for it.” That statement underscores how Republicans are framing the race as a choice about fiscal fairness and accountability.
By contrast, incumbent Rep. Juan Ciscomani supports the Working Families Tax Cuts Act, which projects tax relief and boosts to household earnings over time. Estimates put a typical Arizona household with two children to receive between $7,400 and $10,600 more in take-home pay across four years, with inflation-adjusted wages projected to rise by an additional $3,800 to $6,800.
The federal proposal also targets specific tax burdens: it would eliminate federal taxes on tips, benefiting the roughly three percent of Arizona workers in tipped jobs, and remove taxes on overtime pay, which could help about 23 percent of workers who regularly earn overtime. Supporters add that the bill would extend relief to about 1.3 million Arizona seniors, protect an estimated 133,000 jobs over four years, and permanently preserve the small-business pass-through deduction for roughly 103,000 firms, or about 44 percent of Arizona businesses.
The June-to-November campaign will put these fiscal contrasts front and center. Voters in the Sixth District will evaluate whether the path Mendoza advocates—steeper graduated rates and policies tied to expansive social reforms—is preferable to the tax-cut and growth-oriented approach pushed by Ciscomani and his allies.
