Do I need to send anything if I e-file my tax return?
Generally speaking, 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. I suggest you Print a copy of your Tax Return for your files and Save your Return as a PDF file on your computer. A little more information below.
