How to calculate your cost basis and access cost basis worksheets
Using your own records, determine the date you acquired your shares and the cost per share at that time. If you acquired your shares through participation in the dividend reinvestment plan, use your own records to compute the average cost of all shares purchased through the plan.
Next, go to the worksheet that matches your path toward AT&T Inc. ownership:
- AT&T Inc. shares (formerly SBC Communications Inc./ Southwestern Bell Corporation)
- BellSouth Corporation
- AT&T Corp.
- Southern New England Telecommunications Corporation
- Ameritech Corporation
- Pacific Telesis Group
If you acquired shares through more than one method or at different times, you will need to use the appropriate worksheet for each share acquisition. These interactive worksheets automatically factor in the effect of events listed in the "Events That Affect Your Cost Basis" link. These worksheets will help you arrive at your cost basis.
If your circumstances are different, or if you have any questions, we encourage you to consult your tax adviser.
