Common confusion points

EIN vs. TIN

Both are nine‑digit numbers but serve different parties

→ Verify which number belongs to the corporation versus the recipient

Reporting month vs. filing month

The deadline is based on transaction month, not calendar year

→ Use the transaction date to calculate the due date

e‑file eligibility

Not all corporations are enrolled in IRS e‑file

→ Confirm enrollment before attempting electronic submission

Required attachment

Instructions list a “Statement of Transaction” but many users skip it

→ Attach the statement to avoid a reject

Form edition

Older PDFs may still be circulating

→ Check the edition date on the top of the form
