Hi rwhalen1, thank you for posting an event question.
Congrats on starting a new business last week.
Please use TurboTax Tax Caster to estimate your tax year 2023 tax liability, if any.

Generally, you must make estimated tax payments for the current tax year if both of the following apply:
Depending on your other income and overall estimated balance due, net self employment of $2,000 adds limited income tax and self employment tax (approx. 15.3% of net earnings).
Recommend to use the above $1,000 rule. If estimated balance due for tax year 2023 is less than $1,000, you definitely can wait until last quarterly payment due date of 1/15/2024.
Below is for your information.
