Do you mean you are working now as an independent contractor? Are you doing some sort of consulting etc? If so you will have self-employment income from which you will pay self-employment tax for Social Security and Medicare, and for which you will prepare a Schedule C for business expenses.
As for licensing---that would be a state matter which you would have to explore with your state. The IRS does not require you to have a license to do business as an independent contractor.
