Regardless of your trade, there are so many legitimate tax deductions out there that can be applied to your business (that you may have no idea about). If you are lucky enough to have a bookkeeper or an accountant who is knowledgeable about these, high-fives all around!
Although tax deductions aren't always the easiest things to uncover, taking the time to do a little bit of research will go a long way, and likely save your business some money down the road.
Don't know where to start? Each state typically has some form of small business administration with workshops that review related topics for a nominal fee. SCORE is a great example with regional chapters in California and Michigan.
