The Maryland Reporting Form For Changes Or Corrections (Form DC-47) is a document used to report any changes or corrections to an individual's Maryland tax return. It can be used to report changes to a previously filed return, to correct a mistake on a return, or to add any additional information that was not included in the original return. There are three different versions of the form: one for individuals, one for businesses, and one for estates. Individuals should use the DC-47 form to report any changes or corrections to their previously filed Maryland income tax return, such as changes to their filing status, number of deductions, or income. Businesses should use the form to report changes to their corporate income tax return, such as changes to their entity type, taxable income, or deductions. Estates should use the form to report changes to their estate tax return, such as changes to the decedent's assets, liabilities, or estate taxes. The form can be accessed online from the Maryland Comptroller's website and must be completed and submitted to the Comptroller's Office.
