I don't know all of the tax laws. I have my own accountant handle my books (its nice having a brother who is an accoutant!). I think you are referring to the option of reporting quarterly, which you can do as a business (or maybe anyone can do). I have never done that because I usually make less than $5000 any given year in my small business. I usually itemize on my personal income tax. I believe there is a line than lets you add extra income or loss from income sources other than your primary income source. I also believe that once you start reporting quarterly you have to continue to report quarterly. I guess I'm saying it would be to anyone's benefit to check with a tax professional about the best way to go about this with Kickstarter. I would not let the fear of the US government stop me from accomplishing what Alex and others have.
I wasn't referring to quarterly reporting - I was simply using financial quarters as a time-keeping device. Make a deck Kickstart that ends in Q4 of one year, file your taxes in Q1 of the next year, get the cash back ASAP.
