The Maryland W4 form, officially known as Form MW507, is essential for employees in Maryland to determine their state income tax withholding. This form is specifically designed for Maryland state government employees and must be completed in black ink. It requires personal information, including the employee's name, Social Security number, and home address. Additionally, employees must indicate their marital status and the number of exemptions they are claiming, which cannot exceed the limit specified in the Personal Exemption Worksheet. There are also provisions for additional withholding amounts if agreed upon with the employer. Certain employees may claim exemption from withholding if they meet specific criteria, such as not expecting to owe Maryland tax based on their previous year's tax situation or if they are domiciled in another state, like Virginia or Pennsylvania. The form concludes with a certification section where employees must sign and date, affirming the accuracy of their claims. For further assistance, employees can access the Maryland withholding worksheet online, ensuring they have the most up-to-date information for completing the form correctly.
