When starting a new business it is key to get it all set up legally and to make sure you can begin to file taxes and pay any kind of fees needed to make a business successful.
The first thing you should decide on is what kind of entity you will legally be. For someone just starting their business it would probably be best to be a Sole Proprietor
"A sole proprietor is someone who owns an unincorporated business by himself or herself. However, if you are the sole member of a domestic limited liability company (LLC), you are not a sole proprietor if you elect to treat the LLC as a corporation."
There are other entities and you can find out which is best for you at IRS.Gov. Yet for most the best and "Fee Free" way is to set it up yourself. The next step is to make sure you have an Tax ID # for businesses it is know as a EID (Employer ID #). Even if you are the only person you employ it is still important to file taxes in a business so you can write off business expenses such as Milage, Computers, Supplies and etc. This is where a great tax guy (Accountant) can answer questions and help establish these things.
I have a great accountant who answers my questions, and helps establish the companies EIN. I highly advice you fine one that knows the law, and will take the time to sit with you and help you through the process. Do not feel you can do this all on your own. Even books and websites can be behind on laws or not know about any new tax credits.
GREAT IDEA: If you have a business that you feel you can trade servies for services try to barter. Just remember the Golden Rule "Treat Others how you would like to be treated."
