Amended Income Tax Forms
All forms and some DRS publications are in Adobe Acrobat format. You will need Adobe Acrobat Reader 7.0 or higher to view and print the paper or fillable versions of our forms. For additional assistance or if you are have trouble downloading a form, visit our Adobe Information page.
You can amend your return using the TSC-IND, our free, online filing system. Login to your account and choose the period you wish to amend.
If you cannot use the TSC-IND, you may file a paper amended form.
In general, if you are amending because you believe you are due a refund of income tax you must file the amended return within 3 years of the due date of the original return or, if you submitted a timely request for extension of time to file the original return, you may amend within 3 years of the extended due date or within 3 years of the date you filed, whichever is earlier.
