Do I have to file as a business if I drove for DoorDash in 2024?

Your DoorDash income is self-employment income, for which you are going to owe self-employment tax for Social Security and Medicare, and depending on how much you earned, possibly ordinary income tax as well.

If you have self-employment income for which you will pay self-employment tax for Social Security and Medicare,  you will need to use online Premium software or any version of the desktop software download so that you can prepare a Schedule C for your business expenses.
