It isn't an $800 charge, it is a minimum of $800 in state tax. For an actual business with $20k in revenue the cost is much lower than $800, maybe zero
I know because for a couple years I didn’t owe any state business taxes and thought I didn’t have to pay the $800. I was wrong and had to back pay those charges plus interest. It sucked.
This yearly tax will be due, even if you are not conducting business, until you cancel your LLC.
