If you have someone else prepare your income tax return, you are still responsible for the accuracy of the return. So before you sign your income tax return:
- Review your return with your preparer to make sure it is complete and correct.
- Make sure your paid preparer enters his or her Preparer Tax Identification number or PTIN and signs the return (returns prepared at a volunteer site should have the site identification number but the non-paid volunteer does not sign the return).
- Make sure you have a copy of your return to keep.
