The qbk file extension is associated with QuickTax Suite, financial and tax software developed by Intuit Canada.
A qbk file contains a backup of a tax return file. It is intended to preserve return data so it can be restored in QuickTax Suite.
QuickTax Suite and the qbk format are obsolete. The file may therefore require a compatible older installation of QuickTax Suite for Microsoft Windows.
Open or restore the qbk file in QuickTax Suite on Microsoft Windows. The software must support the version of the backup.
If QuickTax Suite does not recognize the file, it may not be compatible with the installed version.
Restore the backup in a compatible version of QuickTax Suite, then use that software's available save or export options to create a file in another format.
