Choose your business structure
You may operate your business under any of the business structures
below. Make this decision before you ll out any paperwork. Consider
issues such as: how many owners you will have, personal liability, the
complexity of the required paperwork, federal taxes, and whether you
plan to seek investors. You may want to consult an attorney or other
professional for advice on the best business structure for you.
Is your business a: (Choose one. More options on the next page.)
Sole proprietorship
Sole proprietorships are owned by a single person or a married
couple. These businesses are inexpensive to form and have
no special reporting requirements. The owner is personally
responsible (liable) for all business debts and federal taxes.
General partnership
General partnerships are like sole proprietorships but with
more than one owner. Partners share managerial duties, prots
and losses, and each is personally responsible (liable) for all
business debt.
Because the actions of one partner can result in personal
liability for the others, partnerships have become less popular
since limited liability companies (LLCs) have been around.
For federal tax purposes, the business is required to le a
partnership return with the income or loss going to each
partner based on how much of the business each owns.
Prot corporation
Corporations are more complex structures than the others.
As with limited liability companies (LLCs; see next page),
corporations have limited legal liability. To form a corporation,
you must le with the Washington Secretary of State and you
must create a governance document called “bylaws.
Corporations also have other requirements, such as issuing
stock certicates, holding annual meetings and keeping
minutes, electing directors, etc. Working owners of corporations
are employees and must have federal payroll taxes withheld
and be reported the same as other employees. Corporations le
3
federal corporate tax returns with the Internal Revenue Service (IRS). If qualied
and applied for on a timely basis, corporations may choose “pass-through
taxation,” where income taxes are paid by the owner(s) but not also by the
corporation (“S-Corporation”).
Limited liability company (LLC)
LLCs have limited legal liability like corporations but have fewer governance
requirements. Creating an LLC requires ling with the Washington Secretary of State.
For federal taxes, LLCs are typically treated like sole proprietorships if there is
one owner (or a married couple), or like partnerships if there is more than one
owner. However, by ling an “entity classication election” form with the IRS,
LLCs can be treated like corporations or S-corporations for federal tax purposes.
Among other requirements, LLCs are required to create a governance document
called an “operating agreement.
Other options (such as limited partnership, limited liability partnership, limited
liability limited partnership, or nonprot corporation)
These business structures are used less commonly for small businesses. Talk to
your advisor to decide if one of these makes sense for your business.
If you have selected a business structure other than sole proprietorship or partnership and
you havent yet registered with the Secretary of State, you must do so before going forward.
After consulting with your advisors:
Start with the Washington Secretary of States ofce.
Complete the appropriate application online and pay at sos.wa.gov/corps.
Or download forms at sos.wa.gov/corps/forms.aspx and send your completed
application with payment to the Secretary of States ofce (the current fee is on
the application).
The Secretary of States ofce will make sure that another registered business in
Washington State does not already have your business name. Your registration
document with your legal business name will be mailed to you.
The Secretary of States ofce will assign your business a Unied Business Identier (UBI)
number for you to use as identication with all Washington State agencies.
See Step 2 for licensing instructions for the
business structure you choose.

Complete your application for a
Washington business license
Your business must be licensed by the State of Washington as well as
by many cities where your business provides services.
Sole proprietorships and partnerships will be assigned a Unied Business
Identier (UBI) number through the state licensing process. You will use
the UBI for identication with all Washington State agencies.
1. Prepare to apply for your Washington business license.
Be ready to answer questions such as:
What will be the ofcial name of your business?
Will you be hiring employees? Will any be under age 18?
If you wont have employees, would you like to sign up
for optional workers’ compensation coverage? (This is
insurance coverage for you and other owners if you are hurt
while working.)
See the full list of questions you must be ready to answer at
dor.wa.gov/apply.
2. Get the Washington Business License Application:
Online at dor.wa.gov/register.
In person at Washington State Department of Labor &
Industries (L&I) locations listed at Lni.wa.gov/Ofces; at
Washington State Department of Revenue locations listed at
dor.wa.gov.
3. Complete the application and pay the fee, as instructed
online or on the printed form.

Should you be a registered contractor?
If you do any of the following on someone else’s property, register
as a contractor with the Washington State Department of
Labor & Industries (L&I).
Construct buildings and other structures.
Do ooring, roong, siding, painting, install drywall, or similar work.
Install cabinets.
Install plumbing, electrical, HVAC, septic, or other building systems.
(See additional requirements on the next page for plumbing and electrical).
Repair or alter buildings and structures.
Plant plants, build ower or garden beds, or create a path.
Clear land, if it involves cutting trees or moving dirt.
Develop residential property for sale.
Serve as consultant or superintendent on a building project.
Add to or subtract from real property.
Clean up construction sites.
Pressure wash decks, roofs, buildings, or other structures.
You must be a registered contractor to even offer to do work. Dont advertise or
bid a job until your registration is nalized. Once youre registered with L&I, your
ads and bids must include the name and address you used to register and your
registration number.
Do you “flip” (buy, fix up and sell) homes or other properties you have
owned for less than one year?
If you do, youre required to register as a general contractor, even if you hire
registered contractors to do all the work.

Apply to be a registered contractor
Skip this step if you are not a construction business.
Plumbing
Will you offer plumbing-related services?
If your work involves plumbing, you must be registered as
a licensed plumbing contractor with L&I and have a full-
time, certied plumber on your staff. Licensed plumbing
contractors should also be registered as general contractors
if they plan to do construction other than plumbing. Go to
Lni.wa.gov/NewPlumbingRequirements for more information.
Will you use subcontractors for plumbing?
You must be a general contractor to subcontract work. In
addition, general construction contractors must subcontract
all plumbing to a licensed plumbing contractor. The “specialty
plumbing” registration classication is no longer valid. Only
licensed plumbing contractors can hire certied plumbers, who
must do all the plumbing work on-site.
Electrical
Will you offer electrical-related services, including computer cabling,
security systems, replacing light xtures, and other activities?
If you will, you must be licensed as an electrical contractor with
L&I and have certied electricians perform the work. Go to
Lni.wa.gov/ElectricalLicensing for more information.
Will you use subcontractors for electrical work?
In most cases you must be a general contractor to subcontract
work to an electrical contractor.

Know what to do if you hire workers
Did you indicate on your Business License Application that you will
hire employees? If so, the state agencies with tax requirements for
businesses with employees will set up accounts for you. They will mail
you the documents you need and explain the rates you will pay.
You also will need to:
Create an accident prevention plan and meet other workplace
safety requirements.
Find out about employment rules such as minimum wage,
overtime, break requirements, paid sick leave, and authorized
payroll deductions.
Obtain a completed Parent/School Authorization form for
each employee you hire under age 18. Download the form at
Lni.wa.gov/go/F700-002-000.
Set up an employer account with the Internal Revenue Service.
The Washington Small Business Guide has more information and links
to forms you and your employees will need to complete. The guide is
online at business.wa.gov/guide. Helpful websites and numbers are
listed at the end of this publication, as well.
Bring all paperwork and payment to an L&I office
This must include:
Your payment (check, money order, VISA or MasterCard). Ask
L&I for the current contractor registration fee.
Your original completed and notarized Construction Contractor
Registration application. (Notaries are available at most L&I ofces).
Your original insurance and bond documents. (They cannot be
copies and cannot have changes, mar
ks or white-outs, which
will invalidate them.)
Drop off your application at an L&I ofce and Skip the Line by booking
an appointment online at Lni.wa.gov/SkipTheLine.

Know what to do if you use
independent contractors
Many workers consider themselves to be independent contractors. However,
based on legal denitions, they actually would be classied as employees for
minimum wage, overtime, payroll tax, workers’ compensation insurance, and
other purposes.
Steep penalties can result if you are found to be an employer and you
havent met employer requirements. In addition, your clients can face steep
penalties if they should have classied you as their employee rather than as
their contractor.
Carefully review the independent contractor information in
section 10 of the “Start” chapter of the online Small Business Guide at
business.wa.gov/guide.
If you determine the person you’re hiring qualies as an independent
contractor, keep the supporting business documents on le in case you
are audited.
