The red line below shows federal tax receipts. (Data as per US BEA via the Fed)
The black line shows the (top of the) long term trend.

Tax receipts are not a problem.
Taxes are not too-low.
Whatever problems we face are not caused by “the government is not receiving enough tax dollars.”
See a problem? (Price of bananas, or high crime rates, or lousy music these days or, bad healthcare system whatever) It ain’t caused by lack-of-taxes. It is caused by something else.

It would be crazy to spend money based on some pie-in-the-sky idea that the money is going to keep rolling in to Washington. A sane approach to budgeting would be for Congress to assume tax receipts will (long-term) return to somewhere between the black line and the green line. We should budget accordingly.

That sharp decline at the end is a bad sign. It signals some kind of crash in the greater economy. We don’t know for sure because we have never had a decline from this level before.
Safe-bet. Almost certain — federal gov’t tax receipts will return to the normal range, somewhere between the green and black lines.
Likely bet (but who knows?) — The sudden sharp drop at the end means the economy is probably entering a recession, but we can’t be sure.
