Returns are not processed and refunds are not issued if returns are not signed. If you and your spouse file a joint or combined return, both of you must sign the return. Include a daytime telephone number.
If a paid tax professional prepared your return, the preparer must also sign and enter a daytime telephone number and identification number.
The Department will now allow electronic signing of the Declaration for eFile Return form via remote transaction. Returns will not be accepted if the electronic signatures are not digitally or electronically certified. This allows a taxpayer to electronically sign a Declaration for eFile Return form when the Electronic Return Originator is not physically present with the taxpayer.
Check the box on the signature line, and enter the date of death.
If your spouse died and you are filing a joint or combined return, write on the deceased’s signature line “Filing as a surviving spouse”, check the box on the signature line, and enter the date of death.
If you have the legal authorization to file for the decedent, sign the return with your legal title or authorization. Also, include any forms required to be filed with your federal return, such as federal form 1310 or a copy of the court certificate showing your appointment as a personal representative of the decedent.
Spouse Unable to Sign
If your spouse cannot sign because of a medical condition and requests that you sign the return, sign your spouse's name in the proper place followed by the word "by" (your signature), followed by the word “spouse.” Be sure to also sign in the space provided for your signature.
If you are the guardian for your spouse who is mentally incompetent, you may sign the return for your spouse as guardian.
If you are filing a return for a minor child who cannot sign the return, sign the child's name followed by the word "by" (your signature), followed by your relationship, such as "parent" or "guardian for minor child."
Representative Certification Form
If a representative has authority to act on behalf of a taxpayer, they must complete and submit a Representative Certification Form (14-108) prior to receiving the taxpayer’s confidential taxpayer information or acting on behalf of the taxpayer.
