What do tax tables provide?

Tax tables serve the purpose of detailing the federal income tax liability associated with specific income ranges. They allow taxpayers to easily determine the amount of tax owed based on their taxable income without having to calculate it manually using tax rates or formulas. This simplifies the filing process and provides a straightforward way for taxpayers to quickly identify their tax obligations.

In this context, the correct choice focuses on the primary function of tax tables, which is to present clearly the federal income tax amounts applicable to various income levels. By referring to the appropriate table, individuals can find their tax liability directly linked to their level of income, making it easier to prepare their tax returns accurately.
