Ask the Taxman- If I haven’t received my 1099 from my broker but I know the exact amounts, can I still complete and submit my taxes, or will doing so not help expedite its processing?

Answer:
The problem with filing without Form 1099, if you receive it later and it is a higher amount, you will need to amend your return to avoid an IRS notice for unreported income.
I would suggest that you wait. The deadline for filing 1099s is not until January 31.
IRS has announced that they will begin accepting efiled returns on February 12th
