Though I would prefer a 0% income and capital tax, and we move to a pure land value tax and rent tax system.
So I guess you want some level of corporate tax? (it's the same for why there are large sales tax in developing countries; sure they are less efficient than income taxes, but lots of people evade those)
That's why there are specific IRS regulations for this[1]. "Company cars" basically disappeared as a result. Moreover contrary to what you imply, corporate taxes don't really solve this issue either. Corporate taxes are paid on profit, not revenue, and expenses like "work vehicles" or private jets aren't taxed either way.
I believe almost the opposite. We should tax corporations more and individuals less. As long as we keep estate taxes to curtail dynasties.
We have far too much concentration in towards ever larger, more powerful corporations. By their nature corporations lack ethics and morals of normal people. Even when operated by well meaning people the system anonymizes individuals and increases group think, etc. That's not purely a bad thing as it also enables large scalable systems which profit humanity as a whole. However there should also be curtails on corporate power and control.
That's basically what tax on profits are supposed to cover, because a tax on dividends only doesn't cover buybacks.

UK has this, and it's widely considered be economists to be anti-growth.
