JCT: Even With Dynamic Scoring, Republican Tax Bill Will Still Cost $1 Trillion

Republicans in Congress were desperately hoping that the Joint Committee on Taxation wouldn’t have time to perform a dynamic estimate of their tax bill before they passed it. But the JCT wonks put in some overtime and got the job done. Yay wonks! Here’s the result:

  • Over ten years, the tax bill will increase the deficit by $1 trillion rather than $1.4 trillion.

This means that the deficit hawks no longer have any excuse for pretending that the tax cut will supercharge the economy so much it will pay for itself. JCT applied the dynamic fairy dust, but it was nowhere near enough.

As for growth, Republicans were going around saying that all they needed was 0.4 percent higher GDP each year and everything would be great. JCT projects instead that the bill will increase GDP by a little less than 0.1 percent each year.¹

I doubt that this means the bill is in danger of not passing. It just means the deficit hawks have to come up with a different excuse for voting for it.

¹I think. The actual JCT wording is that the tax bill would increase output “by 0.8 percent on average throughout the ten-year budget window.” This is oddly ambiguous. It obviously doesn’t mean 0.8 percent per year, but neither does it mean that GDP is 0.8 percent bigger by the end of ten years (“the increase in output is expected to be smaller towards the end of the budget window”). Truthfully, I’m not really sure precisely what it means, but I think it probably translates into roughly the equivalent of an additional growth of about 0.1 percent per year.

LET’S TALK ABOUT OPTIMISM FOR A CHANGE

Democracy and journalism are in crisis mode—and have been for a while. So how about doing something different?

Mother Jones did. We just merged with the Center for Investigative Reporting, bringing the radio show Reveal, the documentary film team CIR Studios, and Mother Jones together as one bigger, bolder investigative journalism nonprofit.

And this is the first time we’re asking you to support the new organization we’re building. In “Less Dreading, More Doing,” we lay it all out for you: why we merged, how we’re stronger together, why we’re optimistic about the work ahead, and why we need to raise the First $500,000 in online donations by June 22.

It won’t be easy. There are many exciting new things to share with you, but spoiler: Wiggle room in our budget is not among them. We can’t afford missing these goals. We need this to be a big one. Falling flat would be utterly devastating right now.

A First $500,000 donation of $500, $50, or $5 would mean the world to us—a signal that you believe in the power of independent investigative reporting like we do. And whether you can pitch in or not, we have a free Strengthen Journalism sticker for you so you can help us spread the word and make the most of this huge moment.
