As of the time of this posting, the MO state tax calculation (desktop version) is still using the 2022 tax table to calculate income tax.
The old table has a 5.3% top rate and the new table 4.95%. I realize that there are a lot of things to be updated every year, but that's a pretty darn important one to get right! Please update promptly!

Yep, the final MO forms, and proper calculations, are not expected to be ready until after 18 January (according to the TTX state forms webtool Intuit App ).
Thus, the MO forms are not useful, until after that date....assuming they don't change the MO ready date between now and then.
One year, my NC forms were allowed to download early, but were the prior year forms...BUT, some of the line numbers had changed...and the $$$ results were all screwy until the final formset was ready and installed.

TTX is unlikely consider those MO calculations to be a bug until after the final MO forms are issued in mid January....so you should probably ignore everything in the MO section until late January, and run thru the entire Q&A again at that time.
