What income tax rate applies to an investor for non-savings income in investments?

The correct answer is the higher rate, which applies to non-savings income for investors whose total income exceeds the basic rate threshold. In the tax system, non-savings income refers to earnings from sources other than investments, such as salaries or rental income. Depending on the individual's total taxable income, the income tax rates are tiered, with the basic rate applying to lower income levels.

When an investor's income surpasses the threshold designated for the basic rate, they are then subject to the higher rate on the income within that range. This graduated approach to income taxation is designed to ensure that individuals who earn more contribute a fairer share of their income in taxes. Therefore, an investor falling into this higher income bracket will pay a higher tax rate on their non-savings income as part of the overall income tax calculation.

The other choices like the basic rate, additional rate, and exempt status pertain to different income levels or categorization that do not apply when discussing the higher rate specifically for non-savings income across the income brackets for investors.
