Yes, you need to file taxes.
All existing businesses must file a federal income tax return even if the business had no income or activity during the year. States also require businesses to file income tax returns every year, even if the business is inactive.
As a sole proprietor with a federal tax number (EIN), a tax return must be filed for the sole proprietorship, on Schedule C. Filing a Schedule C is required even if the business had no income or expenses for the year.
