I am signing up to have a home-based party business in PA, it is with Brown Bag Parties, a well-known sex toy distributor, its just like home and garden parties or pampered chef parties, and I need to know if you need a business license for that? If anyone that lives in Pennsylvania knows can you please let me know! thanks so much in advance!.--Answer1:You dont need a license to work from home, but you need to keep good record for taxs. You use your SSN# and you file a 1040 tax return listing your expenses and income. You could get a DBA "doing business as" you have to choose a name for the business and get a federal ID # for tax returns. Home based business has a lot of advantages over opening a store.
