Get your taxes done using TurboTax

The default is a calendar year.  Unless you have already entered a Fiscal Year data in the 1040 Worksheet, under the section titled Personal Info, Filing Status, dependent info, you are good to go for a Calendar Year.
In case you need to change TO a Fiscal Year, right-click in the boxes in the section I just noted above, and you will be able to OVERRIDE the default setting (calendar years).  However, if you explore a little further, you will see that TurboTax does not support a Fiscal Year.  pk
