How to File State Income Tax. Every state has a slightly different process for filing state income tax. You will need to access information about your state's specific procedures to find out what you need to do.
Complete Your State Taxes
Check the availability of online tax preparation for your state. Most states list this information, along with companies that provide online tax preparation services, on their websites.
Obtain income tax forms if you have chosen to use print forms rather than file online. You may also want to obtain printed forms if there are only limited online options for filing in your state. Forms are usually available at local libraries and online.
Prepare your state income taxes. If you file online, you will need to complete the questionnaire used by your tax preparer. If you are using printed forms, you will need to complete the applicable worksheets to do the calculations necessary for your income tax forms.
