No? Why not? Why is it that you wait every year until the calendar turns to deal with your taxes? Don't you realize that what you can do to help your 2011 tax situation is much more limited now that it is 2012?
Quite honestly if you were organized the last thing on your mind would be your taxes. You would be more worried about how you are going to make 2012 the best year of business you have ever had. I'm done with both my personal and business taxes. I'm just waiting on various agencies to send me paperwork so I can pass it on to my CPA so he can verify the information I have already provided him.
Make 2012 the year you stop worrying about your taxes. Stay on top of your bookkeeping and do your tax planning before the calendar turns to 2013.
