The federal government recorded a $74.9 billion deficit in June, a month when the government often runs a surplus, as corporate taxes dropped sharply compared to a year ago.

The June deficit pushed the imbalance so far this year to $607.1 billion, 16.1 percent higher than the same period a year ago, the Treasury Department said in its monthly report. The Congressional Budget Office is forecasting that the deficit for the entire budget year will total $793 billion, up 19.1 percent from the prior year, reflecting in part the impact of the $1.5 trillion tax cut that Congress approved in December plus increases in government spending lawmakers approved earlier this year.

The government has run a surplus in June in all but 12 of the past 64 years because it is a month when quarterly tax payments are due from both corporations and individuals.

The tax overhaul bill the GOP pushed through Congress last year reduced the corporate tax rate from 35 percent to 21 percent, although most corporations used various methods to reduce the actual rate they paid under the previous law below the 35 percent figure.
