The correct understanding of how excess percentage depletion over cost depletion impacts taxable income lies in recognizing how depletion deductions work in tax accounting. When a taxpayer utilizes percentage depletion, they can often deduct an amount that exceeds the cost incurred for the property. This excess depletion serves as a deduction against taxable income.

In cases where the percentage depletion exceeds the amount of cost depletion that would otherwise be allowed, this excess acts similarly to any other business expense deduction. Consequently, since it reduces the taxable income, it allows the taxpayer to pay less tax in the year that the deduction is taken.

Although there are various accounting and tax scenarios that could result in different treatment of depletion deductions, the essential aspect here is that excess percentage depletion leads to a lower taxable income in the year it is claimed. Understanding this mechanism is critical for tax planning, particularly for industries dependent on natural resources.

In contrast, the other answers suggest a different way of viewing the impact of excess depletion, either by implying no effect on income or suggesting that it could increase income, which contradicts the basic principles of tax deductions. Permanent differences would indicate that this excess would not reverse or affect future taxable income in a straightforward manner, whereas depreciation affects various periods and can lead to tax management strategies.
