If you are new to TaxSlayer ProWeb and have previously prepared tax returns in another desktop tax program, you may be able to convert some of that program's prior year return data to pull forward into the current year returns in TaxSlayer ProWeb. Returns prepared in a web-based program cannot be converted for use in TaxSlayer Pro.
Here is a list of popular desktop tax preparation software that can be converted for TaxSlayer ProWeb.
Note: Conversion of data is not available for Pay Per Return preparers.
Refer to the attached document below, "Conversion Instructions - ProWeb" for instructions on how to convert the data.
