IMO corporate income tax is the first that should be removed, with a corresponding shift to income taxes. Those can be as progressive as you want, have much lower compliance costs, and don’t distort behavior in the same way. Thought in practice I’m not sure how tax collection from foreign owners would work.

I would rather argue for the following

- No PIT on dividend income, which is fair since CIT has already been paid on the money earned by the firm(and paid bt by you as a shareholder in that firm)

- CIT payable only on dividend distribution, not yearly so if a firm keeps on re-investing in the firm paying salaries/suppliers and investing in growth they don't pay any CIT.

Another side effect of 1) is that it would cause companies to distribute dividends rather than doing stock buyback since dividend would have a lower tax rate(0%) than the STCG/LTCG tax rate on stock appreciation.

This is how estonia does it, so we already have some data on effectiveness of this.
