The Primary SSN for all practice lab returns should have -00- as the 4th and 5th digit. If you are working with support on a specific return, they will need the entire Practice SSN to access the return.
During tax season, we only require EFIN and last 4 digits, however, all Practice Lab returns are created under the same EFIN and there are sometimes thousands that end with the same last 4 digits.
We strongly recommend that if you are working with a support agent on a specific Practice Lab return, you change the last name to something unique to ensure that we can access the correct return.
You should never be asked to email or give a full “real” Social Security Number to TaxSlayer support.
