Would Trump really ax the tax?

Former President Donald J. Trump has spent much of the presidential campaign brainstorming new, and sometimes untested, ways to cut taxes. In the election’s final stretch, he raised the possibility of going even further: eliminating income taxes entirely.

During a Fox News segment on Monday, Mr. Trump took questions at a barbershop in the Bronx. When asked if the United States could potentially end all federal taxation, Mr. Trump said the country could return to the economic policies in the late 19th century, when there was no federal income tax.

“It had all tariffs — it didn’t have an income tax,” Mr. Trump said. “Now we have income taxes, and we have people that are dying. They’re paying tax, and they don’t have the money to pay the tax.”

In June, Mr. Trump floated the idea of replacing federal revenue from income taxes with money received from tariffs. Mr. Trump has not provided specific details of how that would work, and it is unclear if he wants to eliminate all federal taxes, including corporate income taxes and payroll taxes, or only end the individual income tax.

He is following in big footsteps. Here is Ron Paul in 1988: “The income tax is unnecessary.”
