The Utah Amended Matrix (Cover Sheet) is a form used by businesses in Utah to apply for an amended filing on their tax returns. This form is used to reflect changes to the original filing information, such as a change in business address or a change in the number of employees. The Amended Matrix Cover Sheet must be signed and notarized before sending it to the Utah State Tax Commission. There are two different types of Utah Amended Matrix (Cover Sheet): the Single Entity Amended Matrix and the Multiple Entity Amended Matrix. The Single Entity Amended Matrix is used when an individual business entity is filing an amended return, while the Multiple Entity Amended Matrix is used when multiple entities are filing amended returns as part of a consolidated filing. Both forms can be found on the Utah State Tax Commission's website.
