Home / Taxes 101 / Tax Form Difference Tax Form Difference Interview-style eFiling Software Though all IRS authorized tax preparation software must be tested by the IRS, not all are created equal. The IRS publishes tax Forms 1040, 1040A, and 1040EZ to guide taxpayers through the tax return preparation process. Depending on individual situations, taxpayers use additional forms and Schedules (A, B, C, D, etc.) to compute or report additional information. This information is then added into a Form 1040 to complete the tax return. eSmart Tax tax filing software uses an interview approach to tax preparation. As you begin preparing your income tax return online, our software will prompt you with "yes" or "no"-style questions. No confusing IRS-speak for you to decode either. As you respond our intelligent software will gather the data and complete your efile tax return. While you’re answering questions our software works hard to guide you towards deductions you may deserve that will give you the biggest possible refund. We find that many people move through the tax preparation process much faster when faced with straightforward questions that yield easy answers. However, no single tax software is perfect for all taxpayers. Different users at different times may prefer different approaches. If you have not used eSmart Tax before, we encourage you to file your income tax return online with us this year and see for yourself. eSmart Tax: clear preparation process with refund boosting mechanics.
