If you're starting to think about your taxes you might want to take a look at the IRS website. They have done alot to improve their site and many of their publications are now available for downloading.
The Farmers' Tax Guide is available at http://www.irs.gov/publications/p225/index.html
For small businesses and self-employment, check out http://www.irs.gov/businesses/small/
