If I started a business on Dec. 30th 2022, Do I need to file taxes for it this year?

Is your business a sole proprietorship?

If your business is a sole proprietorship, you record all income and expenses from your own personal tax return on the Profit or Loss From Business (Sole Proprietorship) (Form 1040, Schedule C).

You don't have to report the business if you didn't have any income or expenses. However, you can claim expenses even if you don't have any income. 

Also, you might be able to claim start up cost. Start-up costs are amounts the business paid or incurred for creating an active trade or business, or investigating the creation or acquisition of an active trade or business. Start-up costs include amounts paid or incurred in connection with an existing activity engaged in for profit, and to produce income in anticipation of the activity becoming an active trade or business.
