Can I start 2023 self employed taxes now?

The tax year being reported is 2022.  Tax year 2023 will not be completed until after 12/31/2023.

No, as DoninGA points out, TurboTax is currently offering the 2022 tax year and the 2023 tax year will not be available until late this year.

You can use the program to help you estimate your taxes for 2023. You can also use QuickBooks Self-employed to help you keep track of your income and expenses. Click here to learn more.
