Corp. Tax and Profit Levels

Does anyone have any suggestions or advice for where are the best levels for both Corp. Tax and Profit return levels? I understand that if you want outside Corps....well...the lower the tax the better, but for internal use and maximum profit?

I use 15% Tax and 78% profit return, and at these numbers my Corps make money and incur no debt, but are there better ratios? I'm sure there must be.

Any advise?

State Corporations: Tax and PT are irrelevant
Country Controlled Public Corporations: 75% Tax, PT is irrelevant

Auto-transfers occur when cash falls below and goes above certain levels.

Reagrding CCPC, I'm pretty sure PT goes to shareholders by ownership whereas tax goes to country.

If you're not concerned about private corporations, just set tax to 75% and PT to whatever.

thanx

Miz is practically right, but it does help to have some profit transfer coming from your state corps to the country every month of course.

If having high market value for your corps is your thing, then not raiding them for too high profit transfer will help this.

And some corp types you have to watch closer than others, you might think its doing fine but they can then go and buy like 30B of supplies in one go, leaving the corp in defeceit. Then the country needs to send $$$ to the corp and thats not so good.
