Every tax software is a new purchase each tax year because of the development to progam the annual changes to the tax code. Tax software is not like a game or graphics or DTP software. The IRS requires the tax software companies and any storefront tax preparers to comply with stiff requirements designed to prevent misrepresentation of tax events.
The average wage earner could save $50 to $300 per year in tax prep fees or software by just following the line by line instructions included in the tax forms. It really isn’t hard until you start doing things like depreciation, renting property, or operating a business. Even then, it isn’t hard, just more involved.
The rule to follow is: if the line does not apply to you skip it and move to the next line. The instructions are not hard at all – even if you are buying and selling stocks.
http://www.irs.gov/formspubs/index.html download the form and instructions for last year's taxes. Fill out the forms and compare it to who ever did you taxes last year. You will find that you could have done them your self. Having taught tax preparation I'm telling you - you can do it! You appear to be very studious and logical.
Be blessed
