The U.S. government's budget deficit hit $779 billion in the fiscal year that ended Sept. 30, while spending increased and tax revenues remained nearly flat, the Treasury said Monday.
It was the biggest deficit since 2012, and $113 billion more than the figure a year ago. The 2018 deficit amounted to 3.9 percent of the country's more than $18 trillion annual economy, up from 3.5 percent last year.
The government's deficit spending boosted the country's long-term debt figure to more than $21 trillion, forcing the government to pay an extra $65 billion last year in interest on money the government has had to borrow to run its programs.
In all, government spending rose by $127 billion last year, while tax collections increased by $14 billion.
The Treasury said the annual deficit rose partly because corporate tax collections dropped by $76 billion after Congress approved cuts in tax rates for both businesses and individuals that were supported by President Donald Trump.
Mick Mulvaney, the government's budget director, said the country's "booming economy will create increased government revenues — an important step toward long-term fiscal sustainability. But this fiscal picture is a blunt warning to Congress of the dire consequences of irresponsible and unnecessary spending."
