How do I E-File Taxes & Add My Own Attachments?
- 1). E-file your tax return through the e-file website (see Resource section). Be sure to have all your tax documents before starting the process.
- 2). Wait for the acknowledgment that the IRS has accepted your tax return. When you receive it, fill out Form 8453. The declaration control number on the form is the number you received in the IRS acknowledgment. Be sure to check the box next to the appropriate attachment or attachments that you are sending.
- 3). Mail Form 8453 and the attachments to:
Internal Revenue Service
Attn: Shipping and Receiving, 0254
Receipt and Control Branch
Austin, TX 73344-0254
