Business structures (BLS)
When starting a business, there are several different types of business structures to choose from, such as a sole proprietorship, a partnership, or a corporation.
Generally, nonprofit organizations are required to pay sales or use tax on items purchased for their own use. A nonprofit organization must register in Washington if it conducts taxable business activities in the state.
Out-of-state businesses must register with the Washington State Department of Revenue if:
- The business conducts activities that establish nexus in Washington.
- The business collects retail sales tax or other taxes administered by the Department.
- The business collects Washington’s use tax.
If you sell products or services at two or fewer events a year - with each event lasting less than a month - you may request a temporary registration.
