.H12 File Extension
File TypeAt Home Canada 2012 Tax Return
What is an H12 file?
Tax return saved by H&R Block Canada 2012, a Canadian tax preparation program; contains Canadian federal income tax forms and user-entered tax data; saves the progress of a tax return so it can be resumed at a later time.
Since the H12 file extension is used by the 2012 version of At Home Canada, most H12 files are created in 2013 (the following year).
NOTE: H&R Block Canada At Home became H&R Block Canada Tax Software in 2013.
