What's In It

Redemption transaction information including systematic withdrawals and exchanges; redemption trade date and redemption amount; federal income tax withheld and cost basis information.

How To Use It

Boxes 14-16—State information

These boxes will be filled with state-specific information if state backup withholding was taken from the distribution.

Cost Basis Method and Gain/(Loss) 

These two columns are not reported to the IRS and are included for your information only. The Cost Basis Method column indicates the method used to calculate cost basis. The Gain/(Loss) column contains the gain or loss amount for the any wash sales or sales load basis deferral adjustments occurring within the same account. There may be other adjustments that you will need to make to the cost basis for activity between different accounts. See your tax advisor for more information.
