During FY2019, the federal government spent $4.45 trillion, up $338 billion or 7.1% vs. FY2018 spending of $4.11 trillion. Spending increased for all major categories and was mainly driven by higher spending for Social Security, net interest on the debt, and defense. Spending as % GDP rose from 20.3% GDP to 21.2% GDP, above the 50-year average. Also during FY2019, the federal government collected approximately $3.46 trillion in tax revenue, up $133 billion or 3.7% versus FY2018. Primary receipt categories included individual income taxes ($1,717B), Payroll taxes ($1,244B), and corporate taxes ($230B).

Tax revenues in 2018 were about $275 billion below the CBO January 2017 forecast for 2018, indicating tax revenues would have been considerably higher (and deficits lower) in the absence of the tax cuts. The budget deficit increased from $779 billion in FY2018 to $984 billion FY2019, up $205 billion or 26%. The budget deficit increased from $666 billion in FY2017 to $779 billion in FY2018, an increase of $113 billion or 17.0%.
