What is the main function of the Tax Withholding Estimator tool?

The main function of the Tax Withholding Estimator tool is to help accurately determine tax refunds or balances due. This tool is designed to assist taxpayers in understanding how much money should be withheld from their income throughout the year to avoid owing a significant amount at tax time or being under-withheld, resulting in a smaller refund than anticipated. By inputting various financial details, such as income, deductions, and current withholdings, users can receive a personalized estimate of their tax situation, allowing them to make informed decisions about adjusting their withholding if necessary. This greater awareness can aid in financial planning and ensure that taxpayers remain compliant with their tax obligations.
