Iowa Republicans pass major income tax reform

Why it matters: Iowa Republicans tout the move as a major victory that will benefit the balance sheets of all Iowans and attract newcomers to the state.

• Yes, but: Democrats, who largely voted against the bill, warned the ultimate benefactors are the state's wealthiest. They say high-income Iowans have the most to gain from a flat tax rate, while low-income Iowans will see marginal savings.

What's in the bill:

• Gradual reduction to a flat 3.9% income tax by 2026
• Eliminate the state's progressive tax system
• Remove state income tax on retirement income, like 401Ks and IRAs
• Corporate tax rates will gradually reduce

What they're saying: Democrat Sen. Zach Wahls said the median household income in Iowa is $68,000 and those individuals would only see their state taxes reduced by $563, Iowa Capital Dispatch reports.

• But a millionaire would save an average of $67,00 he noted.

The other side: Republican Sen. Dan Dawson argued the current progressive system "penalizes people who work harder" and that every Iowan benefits from the cuts, ICD reports.
