Pressed by Congress and tax policy experts to prove the Trump administration’s claims that its $1.5 trillion tax cut would pay for itself by stimulating economic growth, the Treasury Department’s Office of Tax Policy released a one-page memo that shows it can’t do it.

It projects a budget surplus created by 2.9 percent annual growth in gross domestic product over 10 years — that’s more than 50 percent faster than the most recent forecast by the nonpartisan Congressional Budget Office. Half of that growth would come from corporate tax cuts, the other half from other tax cuts and regulatory reform and from “infrastructure development and welfare reform,” neither of which has advanced past the talking stage.

Scott Greenberg, a tax analyst at the conservative Tax Foundation, called the one-pager “a thought experiment on how federal revenues would vary under different economic effects of overall government policies. Which is, needless to say, an odd way to analyze a tax bill.”

No other analysis — not from Congress, bipartisan tax policy groups, economists, past Republican Treasury secretaries — supports these claims. Instead, most experts say the bill would add at least $1 trillion to the debt.
