There is a growing trend amongst taxpayers to purchase a software package and prepare and file their own income tax returns. In a great majority of cases positive results will follow. There are some difficulties involved with this process. The income tax software packages available on the market are developed to fit a “general” type of return. Despite what the companies say they cannot possibly incorporate all the exceptions to rules and specific circumstances held by a minority of tax payers. Most people who prepare their own taxes make errors in data input. Boxes can be missed and figures transposed.
