The Ohio IT 1040 form is an individual tax return form for Ohio residents created by the Ohio Department of Taxation. As of 2015, it is six pages long and can be returned with federal income tax returns, according to the Ohio Department of Taxation.
The Ohio IT 1040 form requires state income tax return filers to enter a wide range of personal tax-related information including contact information and identification, as well as income information for the previous year. Ohio residents are able to disclose earnings and deductions before filing. The final two pages of the form are designated for disclosing information about dependents, if applicable, explains the Ohio Department of Taxation.
