How to start a pet sitting business in Washington
Pet sitting and dog walking need no degree or state exam, but a few registrations come up in every state. Here is what Washington's own agencies say, checked October 7, 2026. Rules change, so follow each link before you file.
1. Register the business
LLCs file a Certificate of Formation with the Washington Secretary of State. A sole proprietor using a name other than their full legal name registers a trade name through the Department of Revenue's Business Licensing Service ($5 per name plus the application fee).

2. Sales tax on pet sitting
Not taxable
The Department of Revenue says training, boarding, walking and grooming dogs fall under the Service and Other Activities B&O tax, and sales tax does not apply. Selling pet supplies is subject to sales tax.

3. Licenses for boarding and pet care
We found no statewide license for pet sitting or boarding in Washington; the state's dog-breeding law exempts boarding facilities. You need a state business license if, for example, you earn $12,000 a year or more or use a trade name, and many cities and counties license kennels.
