I'd like to know as well. Etsy makes tax reports so difficult. The CSV reports available are really not helpful as you must filter out all the crap not needed for taxes. Why can't etsy provide a simple report of gross, net, breakdown of fees paid, etc. I have to print out all the monthly reports and manually calculate everything.
If anyone has a better way or if I just don't get it, please help.
I agree with other comments here that the PayPal reports are much better.
