Common confusion points
Form number vs. notice number
Taxpayers mix up the supplemental form with the notice that requests it
→ Verify the form number printed on the notice
Electronic vs. mail submission
Some taxpayers think e‑file is always allowed
→ Follow the submission method specified in the notice
Signature requirement
Some believe e‑signatures are sufficient for all supplemental forms
→ Check the form’s signature line for manual signature instructions
Edition date
Using a prior year’s layout can cause field mismatches
→ Compare the top of the form with the IRS website’s current edition
Fee assumption
Assuming a fee is required because other supplemental forms have fees
→ Confirm the notice; this form lists no fee
