How much money do you have to make as a business owner in the city of LA to report taxes?

In Los Angeles, if you're a sole proprietor, you must report income on your federal tax return if you earn $400 or more in net earnings from self-employment. For other business structures, like corporations or partnerships, the income thresholds for reporting can vary. Additionally, California has its own tax reporting requirements, so it's essential to check both state and federal guidelines. Consulting a tax professional can provide clarity based on your specific situation.
