I am a consultant and must pay particular attention to Schedule C and other business expense deduction forms. The book does a good job covering SMB topics broadly and does offer useful tips. However it doesn't not cover the expense categories on Schedule C in anything but broad detail - for instance, it doesnt go into any useful detail about what items should go in Office Expense, versus Supplies or Misc. Expense. The IRS docs are very unclear and antiquated in this regard and so you would hope that buying an outside book on the subject would give more clarity.
Actually the JK Lasser regular book on Your Income Taxes does a better job explaining line by line the IRS forms than this book.
I wouldn't buy the book if you a sole proprietor and are looking for specific info on how to fill out the forms. You would be better off searching for specifics on the web.
Look at the title of this book and you think you are getting up to date information. When I saw that it was talking about 2007, 08 and 09 etc., I groaned. This book is totally worthless if you, like I, wanted a heads up on taxes for 2011.
For the last 15 years, Barbara has (each year) written the finest compendium of Small Business Tax information available! Her simple, easily understood, language, allows the reader to find tax-saving advice on every page (578 pages for 2011!) Barbara understands the tax laws and I totally have enjoyed her business applications that helped me define valuable information to share with my CPA, so that I might be able to leverage that information to benefit my Small Business. I am indeed, honored, that each Friday at 9:00 EST, Barbara shares her expertise with our Cyberspace Community [...] In fact, our Community chose Barbara Weltman to be our Cyberspace Advocate for Small Business 2011. Thank you Barbara!
