Forecaster says US House version of Trump bill to cost $2.8 trillion despite economic gains

WASHINGTON, June 17 (Reuters) - The nonpartisan U.S. Congressional Budget Office projected on Tuesday that President Donald Trump's sweeping tax-cut and spending bill would lead to a $2.8 trillion deficit increase over a decade, despite an increase in economic output.

The budget watchdog issued its dynamic analysis of the legislation that passed the House of Representatives in May, as Senate Republicans considered a revised version of the measure.

Two weeks ago, CBO projected that Trump's One Big Beautiful Bill Act would add another $2.4 trillion to the federal government's $36.2 trillion debt over a decade, without considering the potential economic effects. With interest payments from the new debt included, the cost would rise to $3 trillion.

Independent analysts have estimated that the debt increase could reach $5 trillion over a decade under the Senate version, which makes permanent a number of business tax breaks that would sunset under the House bill.
