WASHINGTON — At a Wednesday afternoon rally in Missouri, President Trump performed up what he known as the “greatest tax cuts in historical past” and boasted about financial development “in a nonbraggadocious method.”

“Actually, they’re going to say Trump is the other of an exaggerator,” he stated of his rosy projections, in a speech stuffed with exaggerations and falsehoods. Right here’s an evaluation.

He’s improper that “for years, they haven’t been in a position to get tax cuts, many, a few years since Reagan.”

President Ronald Reagan, who enacted a significant tax minimize in 1981 and lowered tax charges once more in 1986, was hardly the final president to have completed so. President Invoice Clinton signed the Taxpayer Aid Act of 1997. President George W. Bush enacted two main tax cuts in 2001 and 2003. The stimulus handed beneath President Barack Obama included tons of of billions of in tax cuts, and Mr. Obama later prolonged the Bush tax cuts with the American Tax Payer Aid Act of 2012.

The Run-Up

The podcast that is sensible of probably the most delirious stretch of the 2016 marketing campaign.

He inaccurately instructed the plan wouldn’t assist the rich.

Mr. Trump insisted that the tax invoice is “not good for me” or the rich. Referring to Senator Chuck Schumer, Democrat of New York and the minority chief, the president stated: “I hold listening to Schumer, ‘That is for the rich!’ Whether it is, my mates don’t find out about it.”

That’s not supported by most analyses of the tax plans being thought of in Congress.

Underneath the Senate plan, each revenue stage would obtain a tax minimize in 2019, however individuals incomes $20,000 to $30,000 yearly would face a tax enhance the following yr, in keeping with the Joint Committee on Taxation. By 2027, most individuals making beneath $75,000 annually would see a tax enhance, whereas these making extra would proceed to obtain a tax minimize.

Underneath the Home plan, each revenue group would see tax cuts by means of 2027, however the richest one-fifth of People would obtain 56 % to virtually 75 % of the cuts, in keeping with the Tax Coverage Heart.

Based mostly on his 2005 tax return, Mr. Trump himself may save greater than $1.1 billion beneath the White Home tax framework, in keeping with an evaluation by The New York Occasions, and the identical quantity beneath the Home plan, a tax knowledgeable at Marcum L.L.P. advised NBC.

He falsely known as the present plan the “greatest tax minimize within the historical past of our nation, greater than Reagan.”

Mr. Trump has repeated this declare a minimum of a dozen occasions since October, nevertheless it has not been true of any of the tax plans launched in Congress or outlined by his administration.

A 2013 Treasury Division report assessed the scale of main tax payments both as a share of the financial system, by the discount in federal income or in inflation-adjusted . The 1981 Reagan tax minimize is the most important beneath the primary two metrics. It was equal to 2.9 % of gross home product and lowered federal income by 13.three %. The 2012 Obama tax minimize amounted to the most important minimize in inflation-adjusted : $321 billion a yr.

For Mr. Trump’s tax minimize to exceed the Reagan cuts as a share of G.D.P., the Committee for a Accountable Federal Finances estimates it will have to price roughly $6.eight trillion over 10 years. To have a bigger impact on income, it will have to price $5.7 trillion. No model of the present tax minimize plan meets these benchmarks.

The price range blueprint that Republicans launched in mid-October, the invoice handed within the Home in November and the invoice presently being thought of within the Senate all quantity to a tax minimize of about $1.5 trillion over 10 years. This is able to place because the 12th-largest as a share of the financial system.

He falsely instructed that the inventory market was beforehand flat.

Mr. Trump spoke of tepid development earlier than he took workplace. “In all equity, the inventory market was going this fashion,” he added, drawing a flat line along with his hand. The inventory market has hit document highs beneath Mr. Trump, however the uptick started after the monetary disaster in 2008.

The hyperlink he drew between market efficiency and G.D.P. development additionally contradicts his personal feedback. On Wednesday, Mr. Trump stated the financial system was “doing terribly” at 1.2 % G.D.P. development, which occurred within the first quarter of this yr. However throughout that quarter, he jubilantly posted on Twitter concerning the inventory market’s “longest profitable streak in a long time.”

He exaggerated when he stated a three.three % development was the “largest enhance in a few years.”

The Commerce Division adjusted its estimate of G.D.P. development to three.three % within the third quarter of 2017 from a earlier estimate of three %. That is the most important enhance in about three years, in keeping with knowledge from the Bureau of Financial Evaluation. The financial system grew at three.2 % within the first quarter of 2015 and at 5.2 % within the third quarter of 2014, and the rise was bigger than three.three % in 5 different quarters beneath Mr. Obama.
