In the 1935 case Douglas v. Willcuts, Collector of Internal Revenue, the U.S. Supreme Court ruled on a tax dispute involving stock dividends and capital gains. The petitioner, Lewis W. Douglas, had received additional shares as a stock dividend from his company in 1921 but did not sell them until 1929 when their value had significantly increased due to market appreciation over time. Upon selling these shares, he was taxed by the IRS for capital gains based on their appreciated value at sale rather than their original cost basis (the price at which they were issued). Douglas argued that this taxation method was unfair and violated his constitutional rights. The Supreme Court disagreed with him and upheld the lower court's decision favoring the IRS' interpretation of tax law regarding stock dividends under Section 201(g) of Revenue Act of 1921 - stating that such dividends are taxable income upon realization through sale or exchange based on fair market value at time of disposition rather than initial receipt or cost basis. This ruling clarified how taxes should be calculated for shareholders who receive additional stocks as part of a dividend distribution plan; it confirmed that any increase in share values is subject to taxation once realized through sales transactions.

In the dissenting opinion for Douglas v. Willcuts, Justice Stone argued that the majority's interpretation of tax law was incorrect and overly broad. He contended that Congress did not intend to exempt all income derived from federal securities from state taxation, but rather only direct taxes on such securities themselves. The exemption should not extend to personal income earned by individuals through their own labor or business activities, even if those earnings were indirectly derived from federal securities. In his view, allowing states to tax this type of income would not interfere with any governmental function or violate constitutional principles of intergovernmental immunity as suggested by the majority opinion. Furthermore, he believed that a broader interpretation could lead to unjust results where wealthy individuals could avoid paying state taxes simply by investing in federally-secured bonds while others who earn their living through labor or other means are subject to full taxation.
