Why can I not file my 2018 tax return? I understand I'm late, but can't I still file and pay a penalty?

The deadline for e-filing a 2018 return was midnight in your  time zone on October 15, 2019.  If you did not e-file by the deadline, it is too late.  Now you have to print, sign and mail the return.

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS and/or your state received the return.
