If you are not e-filing your IN income tax return, you would enclose the state copies of the W-2 forms and 1099's that show IN state income tax withholding only.
- If mailing a tax return, please do not staple or clip any of the information together.
- Include all documents loose in the envelope. Stapling or clipping the tax return and additional materials can slow the return’s process and possibly delay customer's refund.
