There's too much wild fluctuation in that chart to be useful. There are tables for the monthly treasury statement with receipts, outlays, deficit/surplus, and another column for financing through extraordinary means which is what the current period falls under for the most part.
Tax receipts are based upon accounting fictions. You can't get any useful information from that, ESPECIALLY when the corporate tax rate has been cut.
Thank you.
But strange that it precedes grey areas, or is it just nothing? Another question - how the gov is going to pay interest on it's debt?
