Tax Hero!
Format: Paperback
I was scraping pennies for supplies in my small coffee shop located in the lowest level of an office building in Cleveland, OH. "Bookkeeping" consisted of a greasy shoe box nestled in the corner near the window. Tax wasn't an immediate concern because I barely had enough to pay rent. Several years passed. The box became larger and greasier. A friendly customer asked whom I would suggest for tax filing. I said, "When you find someone, let me know." When he visited again, he gave me a business card. By now, the box was bulging. I would have been embarrassed to approach a total stranger, but my customer was kind and I imagined his connection being the same. I got a cleaner, newer box and stuffed receipts corner to corner for facing the music.
What does my story have to do with Doug's book?
That scary first filing with the kindest person I've met in my long entrepreneurial career taught me a valuable lesson.
By the time the accountant stopped laughing at my "bookkeeping", he said, "I'm going to help you this year because you're trying to be a serious business person, but don't ever come to my office again with a shoebox. You have to keep records even if its time consuming. You also need to be incorporated, I'll help."
Lucky you! You have a hero.....Doug Collins.

Game Changing Information!
I bought this book months ago and like many others, it found its way to a pile of books I like to call "I'll read them eventually". Yesterday was eventually. A simple read, finished it in one sitting and came away with mountains of info that will save me thousands and even get me money back on previous years taxes. Great info on tax investing strategies as well, well worth the purchase price, and I can't wait to write it off!!

Great advice & tips
Format: Kindle
This book is helpful to new business owners with little to no experience with business tax preparation. I had about 5 pages that was helpful to me because I have had my small business for 8 years and familiar with some of the home based business write offs but there was some useful information that. Are it worth the read.

Easy read, but very repetitive in the beginning
Format: Paperback
It’s an easy read, however it’s very repetitive. I’m about halfway through the book and it still doesn’t really tell me anything. I need to know it’s just talking about. It’s important to keep good record keeping and we will talk about it in the later chapters like I’m already on chapter 13 on page 60 and I’m still waiting to learn more stuff because it’s just repetitive. I’m hoping that changes but it’s a little bit frustrating.
