Common mistakes
- Overlooking remaining Form 1099-K amounts. The form's note says amounts other than those entered at the top of Schedule 1 should be reported elsewhere on your return, depending on the transaction.
- Treating a filing extension as a payment extension. The instructions warn that the automatic 6-month filing extension does not extend the time to pay. Unpaid tax can lead to interest and penalties.
- Mailing a return after e-filing it. The instructions say there is no need to mail an e-filed return.
- Using a private delivery service for a P.O. box. Only the U.S. Postal Service can deliver to P.O. boxes.
