In Washington, you can establish a sole proprietorship without filing any legal documents with the Washington state government. There are four simple steps you should take:
To find out how to establish a sole proprietorship in any other state, see Nolo's 50-State Guide to Establishing a Sole Proprietorship.
1. Choose a Business Name
In Washington, a sole proprietor may use his or her own given name or may use a trade name. If you plan to use an assumed business name or trade name, state law requires that the name be distinguishable from the name of another company currently on record. It is also a good idea to choose a name that is not too similar to another registered business because of common and federal law trademark protections. To make sure your business name is available, run a search in the following government databases:
2. File a Trade Name
If you use a business name that is different from your legal name, Washington requires you to register a trade name with the Washington State Business Licensing Service. This is a mandatory requirement in Washington. To file your trade name you must fill out a Business License Application from the Business Licensing Service. The filing fee is $5 per name.
3. Obtain Licenses, Permits, and Zoning Clearance
Your business may need to obtain business licenses or professional licenses depending on its business activities. Washington provides a comprehensive website of every profession and occupation that requires a license by any sole proprietorship. A business can obtain this information by going to the Washington Business Licensing Service. You will need to file a Business License Application with the State of Washington before you can open for business. In addition, local regulations, including business licenses, building permits, and zoning clearances, may apply to your business. You will need to check with your city and county governments for more information.
4. Obtain an Employer Identification Number
Sole proprietors who wish to have employees need to obtain an Employer Identification Number, or EIN. This is a nine digit number issued by the IRS for tax reporting purposes. All businesses with employees are required to report wages to the IRS using their EIN. Registering for an EIN can be done online at the IRS website.
Sole proprietors without employees are not required to have an EIN because they can use their Social Security number to report taxes. Nevertheless, you may want to obtain one anyway for your business. Some banks require one to open a bank account and it can reduce the risk of identity theft.
In Washington, businesses are required to report taxes and file various employee reports. You may need to use your EIN when registering your business to report taxes through the Washington Department of Revenue. If you have employees, you must report and pay employment taxes on a periodic basis. More information related to employment taxes can be obtained by registering with the Washington Business License Application.
