The income tax laws in the US, UK, and Canada are complex, and a taxpayer usually requires help from a professional tax preparer to file their tax returns. According to the Internal Revenue Service (IRS) of the United States Department of the Treasury, 57.7% of American individual tax returns in 2008 were filed with the assistance of paid tax preparers such as IRS tax lawyers and tax accountants. In the United States, a professional tax preparation service can cost several hundreds of US dollars for an individual or business taxpayer. If a taxpayer does not want to pay for these kinds of professional services, they can seek assistance from a tax preparation software system.
### Commercial or Free Open Source Tax Preparation Software Prices
Tax preparation software can help a taxpayer easily prepare the filing of income tax returns. A commercial software application may be fully-featured but could cost hundreds of dollars. On the other hand, an open source software program is usually available for free download online but does not provide full functionality.
Using an open source tax software program, if you need further information just follow this [link](http://www.jj-tg.com/bbs/boke.asp?jh54mf68ue.showtopic.12300.html), a user may have to do a lot of manual operations to finish filing individual tax returns. But the software will be free, and the user will be allowed to edit the source codes to improve the performance of the software.

Though open source tax preparation software applications are not perfect, they provide simple and free alternatives for personal and business taxpayers. Of course, if a taxpayer finds the preparation work is too complicated, he or she may need to seek assistance from a tax lawyer or accountant.
