State tax forms are the forms necessary for paying state income taxes. Each state that has an income tax produces its own set of forms; these are available online for free through various state government websites.
Though tax forms vary somewhat from state to state, most follow a similar template. The forms begin with fields for the taxpayer to fill out personal identifying information, such as his name, date of birth and Social Security number. The forms allow taxpayers to report dependents or tax exemptions that may affect the total amount they owe. Finally, the form has fields for reporting income and calculating how much state tax is due.
