Is it better to go with the CPA or is completing Form 1040 with TurboTax and sending Form 8858 by mail a standard practice?
If you are familiar and confident in preparing Form 8858, you can can electronically file your Form 1040 in TurboTax and send Form 8858, along with Form 8453 as noted above. If you are less familiar with Form 8858, you may want to consult a CPA.
How will IRS know to match it with my tax return, so that Form 1040 wouldn't be treated as incomplete? Form 8453 is used to mail required forms or supporting documentation and is how forms get attached to the correct tax returns. Filing 8453 will match your Form 8858 to your Form 1040. The process if you choose to file your tax return in TurboTax:
- File your Form 1040 tax return electronically.
- Wait for the acknowledgement that the return has been accepted by the IRS.
- Within 3 business days, mail Form 8453 and Form 8858 to the IRS at the address above (and Form 8453, page 2).
