The Market Value of the Tax-Timing Option: Evidence from Taxable Stock Dividends with Deferring Taxation Option ABSTRACT We estimate the market valuation of the tax-timing option and to what extent this valuation is affected by investors’ tax statuses. By examining ex-day stock price changes for taxable stock dividends, we find that for $1 taxable stock dividend, the deferring taxation option on average results in 18.71¢ tax savings in present values, and a 1% increase in the weighted average tax rate of shareholders produces about 1.68¢ increase in the value of that option. Furthermore, high-tax-rate individual shareholders are more likely to defer realizations of taxes than low-tax-rate individual shareholders, and this suggests the potential violation of tax equity.
