The Michigan 3924 form, also known as the Withholding Tax Schedule, plays a crucial role for individuals who had Michigan income tax withheld during the tax year. This form is essential for reporting both state and city income tax withholdings. When completing your Individual Income Tax Return (Form MI-1040), it is necessary to attach the Michigan 3924 form to ensure proper processing of your return. The form requires taxpayers to input their personal information, including names and Social Security numbers, and to report income from various sources, such as W-2 and 1099 forms. It contains two main tables: Table 1 focuses on tax withheld from wages and other compensation reported on W-2 forms, while Table 2 addresses tax withheld from 1099 forms. Each table requires specific details, including the employer’s identification number, the amount of income, and the corresponding Michigan income tax withheld. Accurate completion of this form is vital, as any discrepancies or missing information could lead to delays in processing your tax return. Understanding the instructions and ensuring that the form is filled out correctly will help facilitate a smoother tax filing experience.
