Your $800 is due with a separate voucher by April 15 2016 because it is only an estimated fee for 2016. It is not related to filing the 568 for 2015. The $800 minimum franchise tax for 2015 needed to be paid by October 15 for any LLC opened in July 2015, or penalty of 1/2 percent per month plus $40 will be charged. I found this out after hours waiting to speak with someone at ftb.
