Have the following information available to complete the declaration:
- Your Mississippi income tax return, Form 80-105 or Form 80-205, for the taxable income, total tax, tax payments, refund and amount owed entries.
- Your name, Social Security number, mailing address and county code, plus spouse information where applicable.

Complete Part I using the corresponding amounts from your Mississippi return. Part II collects direct deposit or direct debit information. Review the taxpayer declaration in Part III before signing and dating it; the form also has a spouse signature and date field.
Your ERO completes the ERO declaration in Part IV, keeps this declaration and provides it to the Mississippi Department of Revenue on request. The ERO's declaration also states that the taxpayer has been given a copy of all forms and information to be filed electronically.
Common mistakes
