What you should know is that there are some requirements to S-corp, C-Corp, LLC, etc... you must be ready to report your activity in a timely manner. You will then need a CPA unless you are proficient in that subject but I guess you have better to do. Fines for not filing on time can be expensive. (at least in California!)
Another thing, unless you pay cash, some suppliers requires to secure the debt when giving payments. Your LLC won't protect you from that since most of the time you guarantee the payment with your personal name.
If you need an SBA, a credit line, a lease, the lender will ask for a collateral. Unless you have enough assets in your business, you'll have to provide them from your personal estate.
Taxes: they won't disappear in case you go broke.
Wages to employees: they won't disappear in case you go broke.
Bounced checks: it's a crime no matter what and YOU are responsible.
Good to know, in the court of California and if you need to appeal, you can't represent yourself if you are a corporation. Get ready to spend big bucks to defend yourself!
If you go into a partnership with a corp, LLC, etc, make sure you amend your agreement with that partner to the articles. Be specific as much as you can. If something goes wrong, you'll thank me later!
So overall, if you have a lot of personal assets that you need to protect them, think outside the box and setup a trust. Unless your business is invoicing a lot, I mean a LOT, or you go into big business with the big boys, a corp is not justified.
So if you are starting, get you seller's permit, your biz license and your DBA, start to make money and watch out for what you do.
Good Luck!
