The Alaska Cover Sheet is a tax form used by those living in Alaska to report their income. It is used to calculate the amount of taxes owed for the year, and is filed along with the state's individual income tax return. There are two types of Alaska Cover Sheets: one for residents of Alaska and one for nonresidents. Both forms require information about the taxpayer's filing status, gross income, deductions, and tax credits. The cover sheet also helps determine the amount of tax due, or any refund due.
