Washington Sole Proprietorship

How to Become a Washington Sole Proprietor

Becoming a sole proprietor in Washington is straightforward. You don’t need to go through any official setup process or pay any fees. To start a sole proprietorship in Washington, simply start working.

However, even though starting is easy, there are some extra steps you might want to consider. While not necessary, many sole proprietors find them helpful.

DBA Acquisition

A Washington doing business as (DBA) name is a crucial part of many sole proprietorships, as it enables you to use an assumed name for your business, rather than your own personal name. The advantages of acquiring a DBA start with image ― most customers feel that an assumed name is more professional and trustworthy than doing business with a company that uses its owner’s personal name instead.

That said, sole proprietors can sign up for a business bank account using their DBA name, which is another step that goes a long way toward making customers feel more comfortable doing business with you.

If you want to use a business name other than your full legal name, you’ll need to a register a DBA (or “Trade Name”) with the Washington Secretary of State. Before doing so, you’ll need to make sure your intended name isn’t already taken by searching Washington’s Business Lookup and the U.S. Patent and Trademark Commission.

After confirming the name is available, you may register it by completing a business license application either online or by mail.

Determine Taxation Requirements

Sole proprietors without employees usually don’t need to acquire a federal tax ID number (EIN), because as a one-person business, you can typically just use your own social security number for most things an EIN is used for. Still, if you would rather not use your SSN for privacy purposes, it would be a good idea to get an EIN regardless.

Beyond that, the nature of your business will determine which taxes apply to you as a sole proprietor.

Although Washington State does not have a personal or business income tax, there are other taxes your sole proprietorship may be liable for. Several common taxes that people doing business in Washington are subject to paying include business and occupation tax, retail sales tax, and use tax. Depending on the nature of your business, other industry-specific taxes may also be necessary.

More information on Washington state taxation in general and how to file can be found through the Washington Department of Revenue.

Obtain Business Licenses and Permits

There isn’t a requirement in Washington for sole proprietors to acquire a general business license, but depending on the nature of your business you may need other Washington licenses and permits to operate in a compliant fashion.

Washington has a wide array of business-related licenses you may need to obtain depending on the nature of your business and where it operates. Thankfully, the state has made the business licensing process relatively simple through Washington’s simplified Business License Application. After completing the application, you will be given the opportunity to add any necessary licenses to your business name.

More information on the Business License Application and how to find it can be found on the Business License Application FAQ Page of the State of Washington webpage.

In addition, you should check to see if your business needs any licenses or permits on the local level.

While the Washington Business License Application does cover some city and local licensing, you’ll need to contact your county clerk or the local government of the jurisdiction in which your sole proprietorship operates to ensure you are meeting all license and permit requirements. For example, Seattle, Spokane, and Tacoma all have their own distinct local standards.

What Is a Washington Sole Proprietor?

As opposed to a corporation or Washington limited liability company (LLC), the sole proprietorship is not a legal business entity. The sole proprietorship is a one-person business that is not considered to be a distinct entity from the person who owns it, and it is frequently operated using the owner’s personal name.

Here are the three main things you need to know:

Tax Responsibilities

Because there’s no distinction between the owner and the business itself, sole proprietors don’t need to file business tax returns ― they instead simply claim any business profits or losses on their personal tax returns.

Contracts

Sole proprietors are allowed to sign contracts using their personal name, and along those same lines, customers can write checks to the business by using the sole proprietor’s name.

More Flexible

The other big difference between sole proprietorships and more formal business structures is the fact that sole proprietors are allowed to commingle business and personal assets as much as they want to. With LLCs and corporations, ownership is required to keep their assets separate from those of the company. The downside of this aspect for sole proprietors is that if your business is sued, creditors are free to pursue your personal assets like your house, car, personal bank accounts, etc. For corporations and LLCs, creditors are limited to your business assets.
