If you receive a Form 1099-B and/or Form 1099-DIV by February 15, these forms should be filed with your annual income tax return.
If you receive a Form 1099-R, this is because you've taken a distribution or rolled assets out of your IRA or 401(k). These forms should be filed with your annual income tax return.
If you receive a Fair Market Value and/or a Required Minimum Distribution statement for your IRA, these forms do not need to be filed. You can check to see if you have any required minimum distributions which must be taken. Learn more about RMDs here.
