This paper examines the relationship between a corporation’s tax rate and a number of different variables. The variables chosen were assets, sales, property, plant, and equipment (PPE), inventory, research and development (R&D), and return on assets (ROA). The model incorporates each of these variables to find a correlation to corporate tax rates. These specific variables were chosen to represent firm size (assets at book value), financial leverage, capital structure (PPE to assets), and inventory investment (inventory to assets). The other two variables, R&D (R&D to net sales), and profitability (ROA) were chosen because of their direct value. The results from the research highlight a few variables with strong correlations to tax rates, while others remained neutral.
