Just make the state a passive non-voting shareholder, with a stake of, say, 10%. It receives a dividend, just like any other shareholder, so interests are exactly aligned, and there's nothing management can do to avoid paying the state, while also paying shareholders. The state would benefit from share price rises by existing capital gains tax paid by the individual shareholders when they realize the equity gain. This would prevent avoidance of dividends in favor of share price appreciation through buybacks. It leaves the problem of cross-border flows, such as fradulent notional payments for intangible assets, such as licensing, which would still be able to move profits and dividends to other countries.
