Schedule C tax form is used to report the income and expenses of a sole proprietorship business to the Internal Revenue Service (IRS). It calculates the net profit and loss of your business, which is then reported on your personal income tax return (Form 1040).

Moreover, this form helps self-employed individuals, such as freelancers, small business owners, and consultants, to track what they make or spend per year in their business. This way, they easily determine the amount of taxes they owe at the end of the year, which helps in calculating the correct tax liability.
