Common Mistakes & Tips

• Enter the name exactly as it appears on your tax return – mismatched names cause processing delays.
• Use the correct Taxpayer Identification Number (TIN). For individuals, this is usually the Social Security Number; for businesses, the EIN.
• Do not leave the "Signature" field blank. Use the built‑in signature tool or type your name and check the "electronic signature" box.
• Double‑check the date format (MM/DD/YYYY) before submitting.
