1. Choose a business name for your sole proprietorship and check for availability.
- Please see our section on choosing and checking the availability of a name for your small business, as well as our section on the trademark law aspects of choosing a name.
2. Register the business name with local, state, and/or federal authorities.
- If you will be operating your sole proprietorship under a name that is different from your own name, then you will need to file an "assumed name" form with the county clerk in the county (or counties) where you will do business.
- Although you are not required to do so, you should consider registering your business name as a federal and/or state trademark. Please see the Trademark for Business Naming section for details.
3. Obtain any required local licenses.
- Please see the general section for details.
4. Determine what tax and other regulatory obligations your sole proprietorship has, and take care of any necessary registrations.
- If you have an employee or employees, you need to apply for an Employment Identification Number from the IRS. You can apply for an EIN online. You may apply for an EIN even if you have no employees. Doing so may make it easier to open a bank account and reduce your risk of identity theft. There is no filing fee.
- If you have an employee or employees in Michigan, you need to register for Michigan business taxes using the Business Tax e-Registration website. There, you will find forms and instructions for all business taxes. You can find more information on this process in the Michigan Business Taxes Registration Booklet.
- Whenever you hire an employee in Michigan, you must inform both the IRS and the State of Michigan. You can find details of all the necessary steps, including verifying work eligibility and withholding allowances, on the Hiring Employees section of the IRS website. You can find state-level information on reporting new hires at the Michigan New Hire Reporting Center website.
- If you have three or more employees in Michigan or have employed anyone for at least thirty-five hours per week for thirteen or more weeks, you must carry workers' compensation insurance. If you are not required to have worker's compensation and you choose not to do so, you must get a certificate of exemption from the Insurance Division. More information is available in An Overview of Workers' Compensation in Michigan.
- As a business owner or employer, there may be other informational returns that you have to file annually or semi-annually with the IRS. For more information, take a look at the IRS Guide To Information Returns.
5. Open a bank account for your business.
- It is a good idea to keep your business's finances separate from your personal accounts. A good way to do this early on is by opening a bank account for your business. The bank will probably require your Social Security Number or EIN and a copy of your business name filing, although you may not need any documentation if your business's name includes your surname. (Here is an example of what banks may require.)
