Starting an LLC in Washington is easy and does not require much effort on your part.

All you need to do is file the documents required by the Washington Secretary of State, file them with the Secretary of State, and pay a filing fee.

You can do all of that in just a couple of days, and once you're done, you can now begin operating your LLC business.

Once your LLC is formed, you can take advantage of the many benefits that come with owning an LLC, such as preventing business liability and providing you with personal liability protection.

There are also LLC tax savings you can enjoy when you choose to start a Washington LLC over other types of businesses.

That should be plenty of reasons to start your limited liability company today.

Create an LLC in just a Few Steps

There are a couple of steps you need to take in order to get your business on its feet. You'll have to:

  • Come up with a name for your limited liability company.
  • Get a registered agent in Washington.
  • Fill out the certificate of formation. This is a simple form that specifies your business name and address, as well as how many members it has and the purpose of your business.
  • Put together an operating agreement.
  • Obtain a unique business identifier from the IRS.

We'll go over each one of the steps you need to take so that you can begin to conduct business as soon as possible.

Step 1: Name Your Washington LLC

First of all, you need to choose a business name.

This is the official title of your business, and it can't be used by any other business that's operating in Washington or doing business there.

If you want to make sure no one else has chosen this exact same business name for their LLC, you should check if the name is available online.

In the state of Washington, an LLC name can't contain any of the following:

  • Business contact information such as a phone number or email address
  • Words that could be considered pornographic in nature
  • Offensive language, including swearwords and racial slurs

If you want to reserve your business name ahead of time with the Washington Secretary of State, you can do so.

The reservation fee is $30 ($50 for an expedited process) and will be valid for 180 business days.

Keep in mind that all business names must be registered with the Washington Secretary of State, so if your business name has already been taken by another business, you won't be able to use it.

It's also possible to get a DBA, which is a business name that you might use when conducting business.

Step 2: Look for a Registered Agent

A registered agent is someone who agrees to accept legal documents on behalf of your LLC when you're not available.

These can include lawsuits, tax notices, and other official notifications from the state.

It can be an individual or a business entity. All that matters is that it's registered in the state.

In Washington, a registered agent must be located in the same county where your company's principal office address is listed.

A Washington registered agent is easy to find. You can look for an agent by asking your personal attorney or using a registered agent service.

Step 3: File Washington Certificate of Formation

Washington LLC's certificate of formation should be filed with the Washington Secretary of State.

In order to file the certificate, you must have a business name that is distinguishable from other names on record in Washington.

The certificate needs to contain all necessary information such as:

  • LLC name and physical street address
  • Registered agent's name
  • LLC purpose - it could be simply "to engage in any lawful act or activity for which LLCs may be organized under the laws of Washington."

You need a certificate of formation to establish an LLC in Washington. It's the most important legal document you'll have to get.

You can either send it by mail or file it online. The online filing fee is $200, while filing by mail is $180. There's a $60 annual renewal fee.

Step 4: Put Together an Operating Agreement

A Washington LLC operating agreement is a crucial part of the formation process.

It's where you define your business, its management structure, and share distribution in case of dissolution or sale.

You should consult with an attorney to help form one if necessary.

However, Washington state law does not mandate operating agreements, so you don't really have to hire an attorney, but it is recommended.

The operating agreement should include information such as:

  • What the LLC will do
  • How much money each member is putting into their initial contribution
  • Roles and responsibilities of all members
  • Restrictions on the transfer of interest
  • Dissolution or buyout provisions in case a member wants to leave the business.

Even though an operating agreement is not a must, it's still a good idea to have one to ensure smooth operations.

Don't skip this important part of LLC formation even though you can.

Step 5: Get an Employer Identification Number

Finally, you can get your employer identification number (EIN), so you can start doing business.

You can get your EIN by completing the SS-4 form and sending it to Internal Revenue Service (IRS).

A federal employer identification number is a nine-digit number that identifies your business for tax purposes.

However, it will also be needed when you open bank accounts and apply for loans.

Also, employer identification numbers are not required by law if the LLC has no employees, i.e., it's registered as a sole proprietorship.

However, it's still beneficial to have EIN if you don't plan to hire employees, so visit the IRS website for more information.

A Business Bank Account: Should You Open One?

It's always a good idea to have a business bank account that's separate from your personal one. You can open business bank accounts at banks or credit unions, and you'll need the following documents:

  • Certificate of formation of your LLC
  • Operating Agreement (optional)
  • The tax ID number for your LLC (EIN).

Separating personal assets from business ones is important to reduce the risk of liabilities and losses in case your LLC gets sued.

It's also beneficial for tax purposes since you will have different filing requirements depending on whether you are operating as a sole proprietor or an LLC with employees.

Having two bank accounts makes it easier to keep track of what belongs where, helps separate business expenses, and maintains the personal asset protection of an LLC.
