The nonpartisan CBO reported that the central drivers of the increasing deficit were the Republican tax law and the bipartisan agreement to increase spending. As a result, revenue only rose 1 percent, failing to keep up with a 7 percent surge in spending, it added.
Revenue from individual and payroll taxes was up some $105 billion, or 4 percent, while corporate taxes fell $71 billion, or 30 percent.
The August statistics were somewhat inflated, however, due to a timing shift for certain payments, putting the deficit measure through August slightly out of sync with the previous year, the CBO noted. Had it not been for the timing shift, the deficit would have increased $154 billion instead of $222 billion.
Earlier analysis from CBO projected that deficits would near $1 trillion in 2019 and surpass that amount the following year.
