The conservative Tax Foundation estimates that GOP tax reform plans would raise the deficit by $1.98 trillion over a decade — significantly more than House estimates — but that increased growth would bring back about a trillion dollars in revenue.

Budget rules approved last week allow the Republican proposal to grow the deficit by $1.5 trillion over 10 years, and the Joint Committee on Taxation estimates the reform bill unveiled Thursday would stay below that limit.

The Tax Foundation estimates hundreds of millions more in lost tax revenue, but said Friday that the bill’s effects on the economy would result in a net loss of $989 billion.

The foundation says the legislation would lead to 3.9 percent higher growth in the long run and 3.1 percent higher wages.

The foundation also found that, before growth effects are taken into account, the top 1 percent of earners would get 3.5 times the proportion of tax benefits as everyone else.

In 2027, it found, all taxpayers would see a 0.9 percent increase in their post-tax income, while the top 1 percent of earners would see a 3.3 percent increase in their already-larger after-tax income.

That figure, however, did not take economic growth into account, which the foundation estimates would boost post-tax income by 4.4 percent, but only 3.9 percent for the wealthiest. That model assumes that labor would accrue 70 percent of the benefit from corporate tax breaks, a controversial assumption that other economists have called into question.
