What is a BA9 File Type?
Only if you file your income tax returns using the TaxAct 2019 software will you likely find a BA9 file. Each annual version of TaxAct has a different extension for backup files. For example, a tax return file created by TaxAct 2017 uses the apos; extension .ba7 while TaxAct 2018 creates backup files with l' extension .ba8. The BA9 files can be manually created by a user or automatically generated by TaxAct 2019.
To manually save with TaxAct 2019, select File → Backup... and name your file. Save your tax return to a TA9 file before creating your backup. To restore a backup in TaxAct 2019 select File → Restore Backup... and browse to the location of your BA9 file.
TaxAct 2019 automatically generates three types of backup files and stores them in the file "AUTO-BACKUP" folder. The three are the current backup, daily backup, and weekly backup. The type can be distinguished from the filename. For example, for a 2019 tax return, the daily backup file BA9 is .ta9 _ daily.ba9.
