After reading and reading about taxes, I think I've grasped which taxes I should pay and when to pay them. Still, it'd be really great if someone could confirm I have it right. I will appreciate any answer, even if you can comment only on certain parts.
The idea is that (a) I'll (very) soon file for a single-member LLC based in the state of California, and (b) I do not expect any revenues (in fact, I will be at loss) for 2011.
My understanding is that:
1) I will have to pass the $0 revenue (or rather -- the losses) from the LLC on schedule C of my personal income tax return by April 15.
2) Once it is confirmed that my LLC has been accepted and registered, I'll have 4 months and 15 days to pay my first California state min tax of $800. And then, I'll have to pay it again by April 15th of 2012. (So even if my LLC exists for just 3 months in 2011, I can't escape the $800 for 2011 unless I wait till 2012, right?)
3) Once my LLC is registered, I need to start sending quaterly estimates. The first one, if I'm correct will be due by Jan 15, 2012, and I'll just have to estimate "$0".
4) And finally (hopefully there are people with businesses in San Fran here), although the company is online based, because of its address, I will also have to file in a Payroll Expense Tax Statement with the city of San Francisco if one day my payroll expense is greater than $150,000.
Did I get anything wrong?/Do you have any suggestions or useful tips?
EDIT: Maybe I should have added a couple more details. The business will be entirely online, but I will be working on it from home, which is why it'll have a San Fran address. Also, I'll start testing the beta site not earlier than December with a number of limited users -- will this count as "doing business" (for the purpose of the $800 tax) if I do not charge them for the testing out the beta?
