1. Research and Plan your Business

The process towards starting a business in Washington demands a well-thought-of initial business plan and thorough research of the business idea. Before actually launching a start-up, conducting due diligence becomes necessary. Comprehensive market research, including analysis of your competitors, becomes essential in determining the potential factors for your business to succeed. Your research should provide a clear understanding of your target customers, your competitors, and how your product or service offers a unique solution.

When you have done your preliminary research, you can use this information to develop an in-depth business plan. Crafting a business plan is an essential part of launching and growing your new business. Despite the general view of having a comprehensive understanding of your business as a reason to forego the business plan, statistics show otherwise. In fact, according to a study by the Harvard Business Review, businesses who created a formal business plan were 16% more likely to succeed than their contemporaries who didn’t have a business plan. Therefore, putting in the effort to create a professional business plan will increase the likelihood of a successful start-up.

2. Choose a Business Structure

Now, it’s time to move on to the next crucial step: selecting a legal structure for your business. It is important to carefully evaluate the level of personal liability risk you are comfortable with, determine the desired tax status, and identify your source of capital. These considerations will help you choose from the four most common types of business structures.

Limited Liability Company (LLC)

Limited Liability Companies (LLCs) are the most commonly adopted formal business structures for small businesses. An LLC is a distinct entity from its owners (also known as members), providing them with personal liability protection. This means that the members can rest easy knowing that their personal assets are safe if the business is sued or has outstanding business debts.

LLCs have numerous benefits, including a preferred pass-through taxation standard. However, they also have the choice to adopt C-Corporation or S-Corporation taxation standards. This flexibility is highly beneficial and is one of the main reasons why so many small business owners opt for LLCs.

Corporation

Corporations are another option for business owners who want to establish a separate legal entity. The shareholders own a corporation through a percentage of shares issued as stocks. While setting up a Corporation has benefits and disadvantages, it offers extra liability protection. However, one thing to remember is that Corporations often have higher tax rates as they must pay corporate taxes before the profits are distributed to shareholders. Overall, establishing a Corporation means taking on additional responsibilities and important decisions that can be challenging but enhance your business ventures.

Sole Proprietorship

If you’re looking for the most straightforward business setup for a single-owner enterprise in Washington, consider a Sole proprietorship. Sole proprietorships require no formal paperwork or registration is outside of the required business licenses and permits. But it’s important to note that while it’s inexpensive to start, sole proprietorships don’t offer liability protection. In case of legal problems or accumulated business debts, creditors can go after the owner’s assets to cover the losses. It’s a good idea to weigh the pros and cons of this business structure before making a final decision.

Partnership

When two or more people co-own a business, the simplest structure is a general partnership. It’s like LLCs in that they benefit from pass-through taxation – this means they don’t pay taxes directly. Instead, they pass profits or losses on to their owners, who then pay taxes on them.

General partnerships are also an informal legal structure, just like sole proprietorships. This means the business isn’t seen as separate from its owners in the eyes of the law. However, this has a significant downside. Members of the partnership have unlimited personal liability for their actions, leaving them open to risks associated with the business.

3. Choose your Business Name

Now that you’re well-informed about legal structures, it’s time to shift our focus to the next step: choosing a great name for your Washington business. While you may be tempted to go with the first thing that comes to mind, thinking that your product or service is what matters most, remember that the name is what initially grabs attention. In fact, the choice of name can significantly impact the success of your business, as it plays a crucial role in your marketing efforts once your business is established. Therefore, it’s worth taking the time to select a good name.

If you find yourself lacking creativity and struggling to come up with suitable names, consider the three essential ingredients of a great business name: creating an identity, being memorable and easy to recall, and being easy to search and find.

4. Register your Business

Following the choice of business structure and name, you must now turn your attention to getting your business in Washington officially registered. The procedure for this varies based on the business structure, so let’s go over each briefly.

Register a Washington LLC

Washington LLCs are formed by filing a document known as Certificate of Formation with the Washington Secretary of State, which has a filing fee of 200. Before doing so, you must determine if the name you have chosen is not already in use. You can do this by completing a Washington business name availability search. Once verified, you can file the Certificate of Formation. The filing must include the LLC’s legal name, the owner(s) contact information, address, and a designated Washington registered agent. While not legally required, you will also want to create an operating agreement to establish the basic rules of how your LLC will function, list ownership percentages, and detail voting rights.

Register a Washington Corporation

To form a Corporation in Washington, you must file a document called Articles of Incorporation with the Washington Secretary of State, which has a filing fee of 200. Additionally, you will need to appoint a registered agent who will be able to collect service of process documents. Designing the bylaws and internal rules for operations is a key way that you can make sure your organization is set up for success.

Register a Washington Sole Proprietorship

At the state level, no formal filings are necessary to start a Washington sole proprietorship. Sole proprietorship owners are required to include their name in the business name. If you wish to carry out your business under a name that does not include your last name, you will have to register a Washington DBA, formally known as a Trade Name, with the state.

Register a Washington Partnership

Similar to sole proprietorships, general partnerships do not require the filing of any official documents to be set up. Also, they must apply for a Trade Name if they plan on doing business under a name that does not include the partners’ names. It is also recommended that the partners create a partnership agreement as it settles many arguments before they arise and outlines a few technicalities such as power distribution and the decision-making process.

5. Get an EIN

Once you have taken the steps to legally form or establish your business, you want to get an EIN. An EIN (an acronym for Employer ID Number) is an IRS identification number for tax filing and employment purposes. You can think of an EIN as the business equivalent of a social security number. Any business formed as a Corporation, Partnership, or LLC is required to obtain an EIN. Even if your business is not required to get an EIN, it’s highly recommended that you apply for one. EINs are required for many business filings and can be used in place of providing your SSN, which can help protect against identity theft.

How to Apply for an EIN

If you have an SSN you can apply for an EIN directly with the IRS for free using the Online EIN Assistant. If you are having trouble or don’t have an SSN you can use Northwest Registered Agent’s EIN service to obtain your EIN.

6. Register for Washington Sales and Use Tax

Washington state has a complex sales tax system, with rates that vary by county and city. The statewide base rate is 6.5%, but localities can add additional taxes on top of the base rate, resulting in an overall rate as high as 10.4%. Businesses must be aware of these taxes and properly register with the state in order to collect and remit taxes. Failure to do so can lead to penalties and interest charges.

How to Know if you need to collect Sales Tax in Washington?

8. Open a Business Bank Account

It’s essential to separate your business transactions and personal transactions to protect your personal assets. Mixing your personal and business banking activity is known as “co-mingling funds” and can cause your business severe problems. Not only does this make bookkeeping and accounting much harder, but it can also result in losing your limited liability status if you’re an LLC or Corporation. If you mix your personal and business funds, you can put yourself at serious legal risk if your business is sued by piercing the corporate veil.

By opening a dedicated business bank account and use it strictly for business activity, you can avoid these risks. To learn more about opening a business bank account, visit our detailed how-to guide. Our guide “How to Open a Business Bank Account” goes over how to choose a bank account provider and the documents you’ll need to open your account.
