Tax revenues have been on the rise for about 18 months. As speculated previously, if this windfall was temporary, it would have shown up with a deficit in April due to a higher than normal tax returns surge. April is historically a positive month for the Treasury, but a surge in tax returns leading to a deficit would have suggested the past year was potentially a fluke.
The US Treasury realized a monthly surplus of $118.7 billion in January. It was the first budget surplus since September 2019 and the largest since it realized a $160 billion surplus in April of 2019.
The surplus was driven by high revenue from a continued surge in Individual Taxes. This was combined with shrinking expenditures due to the expiration of the child tax credits that ended on December 31. The surplus for the month also was helped by $70 billion in proceeds from a wireless spectrum auction.
