Corporations not paying taxes

So I have two countries on LU, a master and a slave. My slave is 100% CEO controlled (one of the reasons I took it) but in my master, I've been trying to fix up my corporations.

I played a few years ago, so I know a bit about the game, but other than that, I'm still "new" only returning a week ago.

Anyway, I noticed that none of the 4 CEO corps in my country were paying tax. In particular, corps that are profitable for the entire period that shows in the graph, were paying 0 tax.

I've actually set my tax to 1% to get an idea of how much money I might be able to get by increasing taxes. Despite that, they seem to be paying $0. I've also set my profit sharing with my state corps at 1%, and, the same problem - despite making a profit, they are sending nothing.

I did recently (IE last day or so I think??) change this from their settings of 0%

This is the country in question

The Teddy Empire Home Territory (all my countries do and will have "Territory" in the name, as that seems as of yet untaken, so it will make it easy to spot my countries when I have a dozen of them)
I set my tax back to 0% overnight, figuring I'd never figure this out, but just now, set it back to 1%. My profit sharing is at 1% as well.
Note that I've nationalized all the corporations that are having "trouble" in some way (most are simply new) as a way to indicate to myself which ones I need to keep a close eye on. I plan to return them to state corporations once they are stable and profitable.

This question needs more data. Switching back and forth from 0 to 1% tax is tough to nail down what should happen. I would guess if you consistently set to 1% you will start receiving a little tax income. An initial change to tax often results in data that is different than what would happen on a "normal" month.

I'll keep it on 1% and see how things go over the long term.

2 months ago, in game, they started obeying orders

If my math is right, this puts the delay at about a year in-game. strange.
