Do I need to send anything if I e-file my tax return?
If you Electronically Filed (E-Filed) your Tax Return you do Not have to sign or mail anything. The IRS receives a Copy of your W-2 and other information. Unless you see instructions on your filing instructions page, you're done once the IRS accepts your e-filed return. That's the beauty of electronically filing your tax returns, nothing to mail. I suggest you Print a copy of your Tax Return for your files and Save your Return as a PDF file on your computer.
Hope this helps.
