Step 1 of 8

Choose a business name

Choosing the ideal business name marks the exciting initial stride in your entrepreneurial voyage. It's akin to christening a ship before embarking on a journey. Your business name should be a reflection of your vision and should encapsulate the essence of your enterprise.

The name you select should not only resonate with your brand but also conform to state regulations. Registering a name already in use within the state is not permissible. Furthermore, it's crucial to include the appropriate designation, such as "LLC" or "Inc.," in accordance with your business structure. By avoiding the use of restricted terms, you pave the way toward establishing a unique and legally compliant business name.

Register your Assumed Business Name

Once you have decided on a name for your company, it is important to take the necessary steps to register and secure it. To begin registration, complete the Business License Application (relevant parts) found on the Washington Department of Revenue website. There is a fee of $5 for each trade name, plus the non-refundable application processing fee.

Step 3 of 8

Decide on a business structure

Deciding on the proper business structure is a critical choice with far-reaching implications for your company. It affects everything from your legal responsibilities and tax obligations to how you manage and grow your business. Here are common options to consider:

  • Sole Proprietorship: This is the simplest form of business ownership, ideal for solo entrepreneurs. As a sole proprietor, you have complete control but also total personal liability for business debts

  • Limited Liability Company (LLC): An LLC combines the ease of sole proprietorship with limited personal liability. It offers flexibility in management and tax benefits while shielding your personal assets

  • Partnership: When two or more individuals team up, partnerships emerge. They can be general (where all partners share liability) or limited (where some partners have limited liability). Partnerships provide shared decision-making but can involve complex agreements.

These structures have distinct advantages and considerations. The key is selecting the one that aligns best with your unique business goals and vision.

Sole Proprietorship

How To Start A Sole Proprietorship:

In Washington, if you want to start as a sole proprietorship, you generally have to apply for a business license because the requirements to operate without it are very strict.

However, there are additional steps that can be beneficial. Although not strictly required, many sole proprietors find them advantageous.

  • First, consider acquiring a "Doing Business As" (DBA) name. A DBA allows you to use an assumed business name rather than your personal name, which can enhance professionalism and customer trust. It also enables you to open a business bank account under your DBA name.
  • Additionally, determine your tax obligations. Sole proprietors often use their Social Security Number for tax purposes, but obtaining an Employer Identification Number (EIN) is advisable for privacy. Be aware of sales tax obligations if you sell products and research other applicable state taxes.
  • Finally, be aware of licenses and permits. In Washington, most businesses need a state business license, and specific industries may also need licenses or permits. Always ensure compliance with local regulations as well.

Partnership

Three primary partnership models exist:

  • General Partnership: No complex formalities or fees are involved, but you don't have limited liability, which means you are responsible for all debts and losses.
  • Limited Partnership (LP): LPs feature limited and general partners. Limited partners hold no liability beyond their investment, while general partners maintain full liability.
  • Limited Liability Partnership (LLP): LLPs safeguard partners from uninvolved debts, particularly favored by high-liability professionals. LLPs adhere to general partnership taxation.

Commencing a Partnership:

  • Register the Business Name: Verify availability in the state's Business Database and register it with Washington's government.
  • Complete Necessary Paperwork: For GP, file a Business License Application; LPs should submit a Certificate of Limited Partnership ($180); LLPs must file Limited Liability Partnership Registration ($180) with the Secretary of State.
  • Secure an EIN and Licenses: Secure an Employer Identification Number (EIN) from the IRS when hiring employees. Explore additional state licenses and tax obligations based on your business activities.

Starting a Washington partnership provides tax efficiency and flexibility while offering varying personal liability safeguards. Select the model aligned with your objectives and consult experts for compliance and informed choices.

LLC

Establishing an LLC:

  • Certificate of Formation: To establish your LLC officially, you must file Certificate of Formation with the Washington Secretary of State. This document includes essential details about your LLC, such as its name, registered agent, and principal office. The filing fee for this document is $180.
  • Registered Agent Appointment: Designating a registered agent is mandatory for all Washington LLCs. This agent accepts legal documents and official mail on behalf of your LLC. You can choose an individual or a business entity to serve as your registered agent.
  • Operating Agreement: While not filed with the state, drafting an Operating Agreement is recommended. This internal document outlines the rules and structure of your LLC, including member roles and responsibilities. Legal fees for creating this document can vary.
  • Annual Report: Washington requires LLCs to file an annual report, which includes updated information about your business. The filing fee for this report is $70.

Starting an LLC in Washington entails document preparation and filing fees, which vary depending on your specific circumstances and needs. Consult with professionals or use online services to streamline the process and ensure compliance with state regulations.

Step 5 of 8

Consider creating an operating agreement

An operating agreement can deliver significant advantages to specific business entities in Washington, including Limited Liability Companies (LLCs), Limited Liability Partnerships (LLPs), and Limited Partnerships (LPs).

Even though Washington doesn't enforce the requirement of an operating agreement for LLCs, it is highly advisable due to its role in defining internal structure, ownership rights, and operational protocols. For LLPs, having an operating agreement is of paramount importance for establishing partner rights, profit allocation, and various operational intricacies. Additionally, LPs may find it essential to adopt an operating agreement, as it facilitates the delineation of partner roles, profit distribution, decision-making procedures, and dissolution protocols.

Step 6 of 8

Obtain EIN

Securing an Employer Identification Number (EIN) is a pivotal step in business registration. This unique nine-digit number, also known as a Federal Tax ID Number, is crucial for your business's identity, similar to how a social security number works for individuals.

An EIN is required for several reasons:

  • Taxation: It's used to file federal taxes, withhold employee taxes, and report business income.

  • Hiring Employees: If your business plans to hire employees, an EIN is necessary for payroll and tax withholding.

  • Opening Business Bank Accounts: Most banks require an EIN to open a business bank account, separating personal and business finances.

  • Legal Compliance: It's needed for legal documentation, contracts, and specific business licenses.

The application process is typically straightforward and can be done online through the IRS website. Once you have your EIN, you'll use it for various financial and legal purposes to ensure your business operates smoothly and complies with tax regulations.

Step 7 of 8

Obtain licenses and permits

This process involves identifying the specific permits your business needs, adhering to local zoning laws, and fulfilling state regulatory requirements. Properly securing these licenses and certificates ensures your business operates legally and avoids potential issues down the road.

In Washington, you need a business license if you meet the requirements

Additionally, Washington imposes specific state-level licenses and permits on various business types and industries. These may include professional licenses, retail permits, and contractor certifications. It's essential to identify which licenses and permits pertain to your business operations at the state level. Ensure you complete the necessary applications and meet all requirements to maintain compliance and avoid any legal complications.

When establishing your business in Washington, don't overlook local licenses and permits. These are specific to your city or county and ensure that your business complies with local regulations. Common examples include zoning permits, health permits, and home occupation permits. Make sure to research and obtain the necessary local licenses and permits to operate legally within your area.
