2015 Income Tax Forms | Individuals & Families

About Prior Year Forms

The forms listed below are only valid for the 2015 tax year. When filing for a prior year, be sure to only use the versions of forms that apply to that tax year, including forms for tax credits and subtractions.

Additionally, prior year forms cannot be used for the current tax year. If a form is listed below, but is not listed on the current tax year forms page, this means the form was discontinued, the filing procedures have changed, tax rules and regulations have changed, and/or the credit/subtraction is no longer available. 

Please be aware that some of the forms below are fillable PDF documents. They have been provided for your convenience. You may type your form entries using a computer instead of filling them out by hand or using a typewriter. These forms must be printed prior to closing out the document, as changes will not be saved in the PDF.
