Taxpayers' 2004 and 2005 joint Form 1040 were prepared using TurboTax. The wife reported expenses for her real estate business as well as unrelated losses on a single Schedule C. Adjustments to this schedule resulted in most of taxpayers' deficiencies and the resulting Section 6662 accuracy-related penalties, and primarily stemmed from the IRS disallowing taxpayers' reported rental losses and recharacterizing the trading losses as capital losses. At trial, the wife argued that they consistently filled out their tax returns using TurboTax and she consistently confused capital gains and losses with ordinary income and expenses. In rejecting taxpayers' misuse of TurboTax, even if unintentional or accidental, as a defense to the penalties, the Tax Court noted that "tax preparation software is only as good as the information one inputs into it."

Aaron's Take: This is a common argument in penalty abatement, however it rarely rises to the level of Tax Court. These taxpayers should have quit while they were ahead. Though, in certain circumstances, you can place the blame for a substantial understatement on your tax preparer, your tax software is not considered a "tax professional" capable of rendering appropriate decisions no your behalf. Sounds like it would have been a lot cheaper for this couple to hire and Enrolled Agent or CPA.
