Thank you for your thoughts.
I trust POTUS Trump, I think running calculations without a passed bill is premature, and I think relying on calculators means buying into undisclosed assumptions. The Breitbart article is encouraging but it’s not soup until the bill is passed.
On the contrary, I think that passing a bill without running calculations is premature. However, I agree that we should not rely on statements and calculators that do not show their assumptions. Everyone should "show their work" to whatever degree is possible. I tried to do that by providing the "Calculation of Taxes" tab to show the calculations above. On the contrary, the great majority of articles and statements I see do not give their calculations. I heard Kevin Brady give 16 taxpayer examples on the House floor on Monday which I've listed at this link. Most of them, he didn't bother do give the income and many of the tax savings appear to be greatly inflated. Yet it seems that nobody is checking the accuracy of any of the examples being cited. Is it any wonder then that many of them appear to be incorrect?
