Drake Tax – 706/1040: Using The Same SSN on Both Returns

Last Updated: October 21, 2026

How to create both an individual and an estate return with the same SSN

You can create a 706 or a 706A return with the same SSN as an existing 1040 return. Using a 1040 return as an example:

1. Create or update the 1040 return. Note the SSN of the return and close the return, if it is open.

2. Back up the original file before proceeding (optional, but recommended).

3. In the software, go to Tools > File Maintenance > Change File Type and enter the SSN and click OK. On the Convert Client Data File Type screen, the selected return is a 1040, so that option is disabled. Note that the list of available return types includes the selections Estate (706) and Heir (706A) on the right side of the screen.

4. Click either option Estate (706) or Heir (706A) to select it and then click Continue.

5. When asked if you want to keep the original return in addition to the new return, click Yes and then click OK.

The SSN is now applied to both the original return and the new return. In the future, when you enter the SSN to open a return, you will be asked which return you wish to open. When you use other features of the program where SSNs are entered (such as in the Client Selection dialog box in Tools > Letters > Letters), you will be prompted to indicate which return the program should use.

This process can be run the other way, starting with a 706 or 706A return to create an individual return with the same SSN.

Use the DISP screen to enter data for the Form 706-A schedules, listed below:

• Schedule A, Disposition of Specially Valued Property or Cessation of Qualified Use
• Schedule B, Involuntary Conversions or Exchanges
• Schedule C, Dispositions to Family Members of the Qualified Heir

To enter data for one of the Form 706-A schedules:

1. Open the DISP screen, accessible from the Form 706-A tab.
2. From the For Schedule drop list, select the schedule to which the screen should apply.
3. In the fields provided, enter the description, schedule letter, item number, and disposition date.
° The Description should match that used on the Form 706 filed for the decedent.
° The Form 706 Sch and Item # boxes should have the letter and item number used to report the property on the decedent’s Form 706.
° The Disposition date is the date of disposition or the date that qualified use ceased for the property.
4. Complete the remaining applicable fields. See the IRS instructions and Drake Tax field helps for more information on specific fields on Schedules A, B, and C.
