President Trump offered an outline for his vision of tax reform in a Sunday op-ed in the Milwaukee Journal-Sentinel newspaper.

Trump connected the issue to Labor Day, writing "we are going to defend our workers, protect our jobs and put America first."

Trump narrowly won Wisconsin in last year's presidential election, using promises of job creation and economic nationalism to woo Rust Belt residents who historically have voted for Democratic presidential candidates.

A push for tax reform was kicked off last week with a speech by Trump in Missouri, but the precise details were left for Congress.

Trump did offer general principles in his op-ed, repeating a call for doubling the standard tax deduction for tax filers and reducing the tax code's complexity.

He also called for lowering the business tax rate, writing "[t]he United States is now behind nations such as France, Germany, Canada, Ireland, Japan, Mexico and South Korea. We are dead last."

"Over the past 30 years, the average business tax rate among developed nations in the Organisation for Economic Co-operation and Development (OECD) fell from 45 percent to less than 24 percent," he wrote.

"Instead of remaining competitive over the same period, we actually raised our rate to 35 percent. When combined with state and local taxes, American businesses today are effectively taxed at 39 percent."

The chances of Republicans pulling off significant tax reform — a feat last achieved during the Reagan administration — is unclear, as the Trump administration struggles with other priorities, failing to repeal Obamacare and seeing little movement on major infrastructure spending.
