TurboTax is a web-based company that allows users to file their tax returns and take care of their personal or business taxes online. Users are then free to submit their tax information to the Federal Government by e-filing through the TurobTax system. It covers all manner of taxes, from just basic filing of W-9 forms to more complicated forms such as 1099. There are also all manner of other forms that could possibly be included with the filing process. For instance, a non-standard injured spouse form for those that have a spouse that owes the IRS or some other governmental entity money that was an incurred debt before the marriage took place.
TurboTax also has a downloadable version of their web software available. However, once installed on your computer all of the components must be present in order for the TubroTax software to function properly. The 1PH - TurboTax file is a file extension that is used by this particular software program. Versions of the software that support the 1PH file include the Intuit TurboTax Deluxe and the Intuit TurboTax programs. If you are using either one of these versions, you should have no problem opening up a 1PH – TurboTax file extension.
