If you want to set up as a DBA, go to the IRS site here: [
www.irs.gov] and apply for an EIN (Employer Identification number). When registering, you must use your full real name and then add DBA whatever your business name is. It should look like this: (Example is a fake name and fake company) John P. Doe DBA Best Mystery Shopping Company In The World.
Other things you should do: You receive the EIN number immediately after applying. You will use this number instead of your social security number. Then, go to your local courthouse and apply and pay for an occupational license with your DBA (My area it cost $50). In addition, I suggest getting insurance for Mystery Shopping with your DBA. Also, you can open up another checking account with your DBA but, you are allowed to use your personal account if you want to.
