It may depend on the type of business, but chances are that you do not need a license. There are many different types of filings and licenses depending on the business, but they aren t for everyone. If you re thinking of setting up somewhat of a hobby business to run online you don t really need a license.If you get into buying and selling stuff online though, your should contact an accountant. Just because you don t need a license doesn t mean that your tax liability won t change.
I would contact your Secretary of State. They should have a list of businesses that require licenses or at least be able to direct you to the right resources. Since you specifically mention the site will involve money, I would suggest contacting your department of banking to be sure what you plan is legal. Some financial activities are regulated by the SEC so you might want to check there as well.Good Luck
