Many assume filing is still required
→ Verify that total withholding = $0 before skipping
Confusion: Which form the buyer should use
Buyers file Form 8288‑A, not 8979
→ Check the buyer’s role in the transaction
Confusion: Deadline extensions
Extensions apply only if you file a related return
→ Confirm extension eligibility
Confusion: Electronic vs. paper filing
Some foreign entities lack FIRE access
→ Choose the method you can complete
Confusion: Reporting a refund
Refunds are reported in Part IV, not Part III
→ Ensure correct section is used
