Auto tariffs could cost low-income earners tax cut money

June 10, 2018

Donald J. Trump arrived in Quebec for the G-7 meeting with some controversial ideas (notably, letting Russia back in the club) and he left the international meeting the same way.

Tweeting from Air Force One as he headed to Singapore to meet with North Korea's Kim Jung Un, Trump gave notice he's ready to escalate trade disagreements with Canada by imposing automobile tariffs.

The initial reaction has been what such a move could actually mean to the U.S. automotive industry.

Tax cut tariff costs: But auto tariffs also could undermine any gains from the TCJA, according to a Washington, D.C.-based tax policy think tank.

And the taxpayers who would feel the negative effects most are low-income households.

"We estimate that increasing tariffs on automobile imports would reduce the gain in after-tax income for households in 2018 derived from the Tax Cuts and Jobs Act while making the tax code less progressive," says Erica York, an analyst with the Tax Foundation.

York notes in her article posted at the tax policy nonprofit's website that economists generally agree that free trade increases the level of economic output and income, and conversely, that trade barriers like tariffs reduce economic output and income.

The full effect of any tariffs would be long-term, but if ultimately imposed, York says "these automobile tariffs would fall more on middle- and lower-income taxpayers, reducing the increase in income these households would see because of the Tax Cuts and Jobs Act, and making the distribution of the tax burden less progressive."

How much so is shown in the Tax Foundation table below:

Auto tariff projected impact on TCJA gains

Bigger tax break, less tariff effect: Overall, the Tax Foundation projects that new tariffs on automobiles reduce after-tax income gains for all taxpayers by 0.47 percent or a 16 percent change.

Those in the bottom 80 percent of earnings, however, would see their after-tax income gains from the new tax law cut by 0.49 percent or a negative impact of 49 percent on their tax change earnings.

That's almost half of the 1 percent income gain those households are expected to get from the TCJA.

And that's why the 0.49 percent potential TCJA tariff bite is this week's By the Numbers figure.

It could be that Trump's tariff talk is primarily bluff and bluster, as he doubled-down while en route to the meeting with Kim. As his advisors noted, he wants to appear as strong as possible for those discussions.

But trade matters have been a major political plank for Trump from the get-go of his political career. So, as Trump is fond of saying, we'll see.

Tax Season 2026 Continues!

We made it. Tax Day 2025 is finally over. For most of us. When the filing season started on Jan. 26, millions who were expecting refunds filed immediately. Most of us got our returns to the Internal Revenue Service by April 15. But plenty of taxpayers also got extensions. They are looking at an Oct. 15 filing deadline.

Those procrastinating filers aren’t a problem. In fact, the IRS appreciates taxpayers who take time to fill out their 1040 forms correctly. It also is grateful that tax submissions are spread out a bit, especially now that the IRS is a leaner agency. Processing returns is easier when they arrive throughout the year instead of in massive bunches.

But enough about Uncle Sam’s tax collection issues. The focus now is on all y’all who filed for extensions, giving you another six months to complete your return. Since your new mid-October due date will be here before you know it, let’s get started now on meeting it.

The ol’ blog is here to help you finish up your extended Form 1040. You can start with January’s tax tips page, which has links to the rest of the year’s tips by-month collections. You also can peruse various tax categories for more tailored advice by clicking on the More Tax Posts drop-down menu at the top of this (and every) page.

And to make sure you don’t miss your new filing deadline, the count-down clock below will let you know just how much time you to file by Oct. 15. At the latest.e. (Note: I’m in the Central Time Zone, so adjust accordingly for where you live.)
