Here is an outline of the steps you need to follow in order to form a partnership in Washington. You should also read the general section on forming a partnership for information applicable in any state.

1. Choose a business name for your partnership 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.

• Consult Access Washington for information on how to check the availability of your desired business name in Washington.

2. File a Business License Application with the Washington Department of Licensing.

• Washington uses a single form for many of the steps needed to start a business. This form is called the Business License Application.

• Before filing out the Business License Application, get the Business Licensing Guide so that you will fill out the application correctly.

• You can file the Business License Application by printing out the form and mailing it, applying online, or by visiting a business licensing office in person. The filing fee is $20, which is a processing fee of $15, plus $5 to register a trade name. If you filed formation papers with the Secretary of State, write the Unified Business Identifier (UBI) number that was given to you on your Business License Application.

• When you file the Business License Application, you will receive a state business license and a Unified Business Identifier (UBI) number (if you did not already receive one from the Secretary of State's office).

• The Business License Application lets you register a "trade name" for your business, which you will need to do if you will operate your sole proprietorship under a name other than your own name. In addition to this, consider registering your business name as a federal and/or state trademark. Please see the Trademark for Business Naming section for details.

• The Business License Application also lets you create a state employment account, which you need to do if you will have an employee or employees in Washington. You should not set up an employment account unless you plan to employ someone in the next 90 days.

• Check your local county or city clerk's office for any additional licensing requirements.

3. Draft and sign a partnership agreement.

• Although not legally required, it is strongly suggested that you and your partners sign a partnership agreement laying out the rights and responsibilities of the partners. For details, please see the Partnership Agreements section.

4. Get an Employer Identification Number from the IRS.

• Request an Employer Identification Number (EIN) from the IRS. This can be done via its online application. There is no filing fee.

5. Report Any New Hires.

• Whenever you hire an employee in Washington, you must inform both the IRS and the State of Washington. 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 about reporting new hires at the Washington New Hire Reporting website.

• If you have an employee or employees in Washington, you need to carry workers' compensation insurance. The Washington State Department of Labor & Industry administers the program. Its website has a useful Intro to L&I's Workers' Comp Insurance page.

• As a small 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.

6. 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. You will probably need a Tax ID number (EIN) and either a copy of the partnership agreement or a business name filing indicating the partners' names. (Here is one example of the documentation banks ask for.)
