Although firms account for entity-level taxes, they do not account for shareholder-level capital gains and dividend taxes. To account for these proprietary-level taxes, we add them to a residual-income equity valuation model. Empirical analysis supports the model's predictions. First, both capital gains and dividend taxes reduce investors' implicit valuation of the reinvested portion of earnings. Second, dividend taxes reduce the valuation of the portion of earnings distributed as dividends, but capital gains taxes do not. Third, dividend taxes reduce the valuation of retained earnings equity, but again, capital gains taxes do not. These findings suggest that investors implicitly extend entity-level accounting to the proprietary level when they value the firm. The findings also suggest that when fully accounting for the effects of implicit dividend taxes, reinvested earnings appear to be subject to three levels of taxation—corporate, dividend, and capital gains taxes. Paying earnings out as dividends eliminates the capital gains layer of tax and may provide a net wealth benefit for shareholders, rather than a tax penalty as commonly assumed.
Prior empirical evidence regarding the impact of dividend taxes on firm valuation is mixed. This study avoids some of the complications encountered in previous empirical work by exploiting institutional characteristics of REITs, such as their limited discretion over dividend policy and the relative transparency of REIT assets. We regress the market value of equity on the market value of assets and tax basis, which creates tax deductions that lower future dividend taxes without affecting future pretax cash flow. We find that firm value is positively related to tax basis, suggesting that future dividend taxes are capitalized into share prices.
In this study, we use cross‐sectional regressions to estimate the value of the debt tax shield. Recognizing that debt is correlated with the value of operations along nontax dimensions, we estimate reverse regressions in which we regress future profitability on firm value and debt rather than regressing firm value on debt and profitability. Reversing the regressions mitigates bias and facilitates the use of market information to control for differences in risk and expected growth. Our estimated value for the debt tax shield is approximately 40 percent (10 percent) of debt balances (firm value), net of the personal tax disadvantage of debt.
