The Missouri 4160 form serves as a crucial tool for individuals looking to update their mailing address with the Missouri Department of Revenue. This form is essential for maintaining accurate records across various departments, including driver license records, individual income tax records, and motor vehicle records. When filling out the form, applicants must provide personal information such as their last name, date of birth, and the last four digits of their Social Security number. Additionally, the form requires details about both the old and new mailing addresses, ensuring that all correspondence reaches the correct location. For those updating their driver license records, it’s important to note that this form only changes the mailing address. If a residential address change is desired on a driver license or instruction permit, a separate application and payment are necessary. Furthermore, the form includes sections for listing vehicle details, such as license plate numbers and expiration years, which helps keep motor vehicle records current. Individuals seeking to change their business address must use a different form, specifically the Registration Change Request (Form 126). For convenience, the Missouri Department of Revenue also offers options for online address updates. Overall, the Missouri 4160 form is a straightforward yet vital resource for ensuring that personal and vehicle records are up to date.
