Corporate Tax Rate Schedule Marginal corporate tax rates Using the corporate tax rate schedule given here , perform the following: a. Find the marginal tax rate for the following levels of corporate earnings before taxes: $15,100;$61,900;$91,400;$195,000;$403,000;$1.4 million; and $19.7 million. b. Plot the marginal tax rates (measured on the y axis) against the pretax income levels (measured on the x axis). Explain the relationship between these variables. The marginal tax rate for earnings before taxes of $61,900 is The total taxes due for earnings before taxes of $61,900 is $ The marginal tax rate for earnings before taxes of $91,400 is The total taxes due for earnings before taxes of $91,400 is $ The marginal tax rate for earnings before taxes of $195,000 is The total taxes due for earnings before taxes of $195,000 is $ The marginal tax rate for earnings before taxes of $403,000 is The total taxes due for earnings before taxes of $403,000 is $ The marginal tax rate for earnings before taxes of $1.4 million is The total taxes due for earnings before taxes of $1.4 million is $ The marginal tax rate for earnings before taxes of $19.7 million is The total taxes due for earnings before taxes of $19.7 million is $ o.
