Business license info for home-based bookkeeping?

[komrad]

Asking for a friend.

1. Does she need a license for Torrance, CA (Los Angeles Area) for doing bookkeeping (for many clients)? (She is the sole employee... lol I'm going to help her out a bit but I won't count as I'm won't be paid.)
2. If so approximately how much does it cost (range)?
3. Obviously if she gets one she gets a license she gets business taxed. If she is the only person getting the income does she get taxed twice (business and then income tax)?

Oh yeah, also approximately what percent tax do they take for a small business?

I look forward for your reply.

This is probably something more suited for your local attorney.

This is probably something more suited for your local attorney.

Or the CA State Attorney General's office or small business administration. I am sure they have all the requirements for small business.
