For example if a corporation was selling something at $2 when corporate taxes were 20%, they will not raise prices if corporate taxes were 40%. If that were not the case, they would have raised prices earlier and increased their profits. Corporations set prices where marginal revenue equals margin costs. Corporate income taxes which area percentage of pretax profits do not impact marginal costs.

Raising Corporate income taxes whose incidence falls
entirely on the owners of corporations, would have absolutely no effect on wages, employment or prices since every corporate decision regarding on wages, employment or prices that maximizes pretax income also maximizes after-tax if corporate taxes are a percentage of pretax income.

Not so fast:

The consumer takes the hit in most cases too, in the form of higher prices since tax is an expense like anything else and it needs to be recouped to sustain the corporation. Also, if the corporation competes internationally any relative disadvantage that taxes place on it weighs against its viability, which directly involves employees’ future prospects of employment. Its fair to say that all of the constituents of a corporation are potentially affected by its taxes, not just the shareholders.

Like many things in life, this is complicated.

Throwing out leaders like the original thread might excite and provoke, but does little to educate.

Since 1969 there has been a tremendous shift in the tax burdens away from the rich on onto the middle class. Corporate income tax receipts, whose incidence falls entirely on the owners of corporations, were 4% of GDP then and are now less than 1%. During that same period, payroll tax rates as percent of GDP have increased dramatically. The overinvestment problem
caused by the reduction in taxes on the wealthy is exacerbated by the increased tax burden on the middle class. While overinvestment creates more factories, housing and shopping centers; higher payroll taxes reduces the purchasing power of middle-class consumers. …”

GDP measures “stuff the nation produces.” Tax receipts measure “stuff taken as taxation by government.” The ratio of the two directly translates to “what fraction of what is produced is taken by the government?”

Reenues/GDP is one of the very few simple measures that isn’t screwed up by distributional issues. For example, a country that taxes individuals at a high rate but corporations not at all may seem to have a higher tax burden from an individual’s perspective, but may in fact be lower-taxed (net) than a country with a different tax structure.
