Query about LLC
1 - Do i need an accountant?
2 - I will show my company address in my resident country - is it possible?
3 - I am mostly doing business outside of US. Can I publish my invoice and use it giving my origin address and bank account in my country?
1 - you only need an accountant if your company has tax filing obligations in the U.S. A company that has no activity in the U.S. and whose owners are none U.S. persons living abroad then usually it doesn't need to file anything with tax authorities.
2- Foreign address as primary business is OK.
3 - You can use foreign address and foreign bank account to transact business of a U.S. registered entity, no problem.
