How does cutting taxes encourage them to bring it back?
How does our highest rate in the developed world encourage them to bring it back?
They pay ZERO now, they pay ZERO if taxes are cut.
We should move to a territorial system.
If they can pay ZERO why would they choose to pay ANYTHING?
They might like to use that money in the US.
Big surprise. Your answer was not even close to adequate. They pay zero now, they pay zero under the new plan. There is no incentive to return that money to the US unless, as you did point out, they want to use the money here. But where is the demand going to come from? And I believe I previously pointed out to you that the highest corporate tax rate in the developed world is in the United Arab Emirates. It appears there is no shortage of businesses more than willing to invest in Dubai, and the police force there drives Lamborghinis.
Now I wondered how the hell those economists from Boston University could come up with such a figure considering what I know about the history of previous corporate tax cuts. So, unlike probably anyone else here, I found the study.

Now, they got that growth in GDP by plugging the numbers into the Global Gaidar Model. I laughed out loud. The irony of touting a study based on a model designed by RUSSIAN economists can't be overlooked. But, there are some things we can take from the study. For instance,
Indeed, cuts in personal income tax rates in the GGM produce deficits, crowd out capital and lower long-run economic welfare.
Guess that tax cut for the wealthy should be pulled off the table. And then this,
This said, we share the TPC’s concern that the UF plan could disproportionately benefit the top 1 percent. This concern about fairness as well as the country’s massive long-term fiscal gap suggests modifying the UF plan to include, for example, the elimination of Social Security’s FICA tax ceiling, a tax on lifetime inheritances and gifts received above $5 million, or a progressive cash flow tax on consumption above $100,000
And there goes the elimination of the estate tax. Plus, I got to tell you, I love the idea of eliminating the ceiling on FICA taxes and implementing a cash flow tax on consumption above a hundred grand.
But the biggest problem with the study is the numbers plugged in. You know the saying, garbage in, garbage out. They plugged in a marginal EFFECTIVE tax rate of 34.6% and a new rate of 18.6%. The problem, the marginal EFFECTIVE corporate tax rate is no where close to 34.6%. Here is a study that pegs the EFFECTIVE corporate tax rate on new investments at 24%.
Actual U.S. Corporate Tax Rates Are in Line with Comparable Countries
So, in summary, the study in the OP assumes an extraordinary high effective marginal corporate tax rate that is not based on reality and ignores the additional components of Trump's tax plan like the personal income tax cut and the elimination of the estate tax. In fact, the study advocates maintaining the estate tax and a significant increase on taxes of the wealthy by eliminating the cap on FICA taxes.
