Tax brackets are a crucial aspect of the income tax system, as they establish the rates at which different portions of an individual's income are taxed. The tax code is designed with multiple brackets, meaning that income is taxed progressively; as a taxpayer's income increases, they may move into a higher bracket, subjecting the additional income to a higher tax rate.

This structure enables a fairer approach to taxation, where higher earners contribute a greater percentage of their income compared to lower earners. It is essential for taxpayers to understand their tax bracket, as it influences not just how much tax they owe, but also how their financial decisions—such as bonus income, investments, or retirement savings—are ultimately taxed.

The other options highlight concepts that are not determined by tax brackets, such as deductions, filing deadlines, or limitations specific to investment income. While deductions may lower taxable income, they do not dictate the brackets themselves. Similarly, the filing deadline is a separate aspect of tax policy unrelated to how income is taxed. Lastly, tax brackets apply to all income, not just investment income. Understanding tax brackets is therefore fundamental in grasping how tax liability is computed for different levels of income.
