In the spirit of the Centennial Accord and in accordance to SB 6175: “Promoting Government-To-Government Relationships with Tribes” the Department recognizes the inherent authority of tribes to regulate and tax activities within its Indian country.  In addition, federal Indian law and policy supports the rights of self-governance for Indian Tribes.  Under these same principles, the state also has a recognized interest in taxes on non Indians/State citizens.  Promoting understanding of these laws is in the best interest of the state as well as the tribes to make use of the Federal legal framework provided to efficiently find agreement to address areas of potential jurisdictional conflict through government to government consultation and cooperation rather than through conflict and litigation.   

This page is designed to educate tribes and tribal members/citizens about Washington State Taxes.

If you are a non tribal entity and doing businesses in Indian country see our Indian Guide to find what you need to know about doing business in Indian country.

What tribes and tribal members/citizens should know

Tribal members/citizens do not pay state taxes for their transactions that occur in their Indian Country. This means state taxes are inapplicable when:

  • You have a service performed for you within your Indian country.
  • You purchase items within your Indian country.
  • You pay for utilities, e.g., phone, water, electricity, trash collection, that serve your home or business in your Indian country.
  • A product or service is purchased by you and delivered to you in your Indian country
  • You own and operate a business in your Indian country; however, you may be required to collect state retail sales tax from non tribal citizen customers and report and remit the taxes collected.

Tribal tax may, however, be due on any of the above. Ask your tribal government if tribal tax is due.

Documenting your tribal exemption

Washington taxpayers must document the reason a sale is exempt from collection of a tax; otherwise, they may owe the tax. Therefore, retailers may ask you to fill out one of the following forms:

How to get a refund

You can apply to the Department for a refund if the retailer does not provide you an exemption to which you are entitled. To apply for a refund you need:

Property Tax

When tribal lands are held in trust by the Federal Government, that property and the improvements on it are exempt from property taxes when owned by a tribe or its members/citizens. When land is owned by a tribe or its members/citizens in "fee" patent (as opposed to being held in trust by the Federal Government), the property is subject to property taxes.  The tribe may apply for an “essential government services” exemption from the property tax for its land owned in fee.  “Essential government services” is defined as "services such as tribal administration, public facilities, fire, police, public health, education, sewer, water, environmental and land use, transportation, and utility services." In 2014, the Legislature passed Engrossed Substitute House Bill (ESHB) 1287 to recognize "economic development" as an essential government service for the purposes of qualifying tribally owned property for property tax-exempt status. For more information, see our ESHB 1287 (Chapter 2017, Laws of 2014) page. Complete and submit a Declaration of Tribal Land Used for Essential Government Services.

Personal property is defined as the moveable furnishings or equipment used in business. When personal property is owned by a tribe or tribal member and kept in "Indian Country," it is exempt.

If a Tribe or Tribal member/citizen sells their house within their own Indian country, real estate excise tax does not apply.

If you have questions about specific property tax situations relating to Indian property, call our Property Tax division at (360) 534-1400.

Vehicle purchases

Tribal members/citizens can purchase vehicles exempt of retail sales tax and use tax if the seller delivers the vehicle to the tribal member/citizen’s Indian Country.

However, tribal citizens/members must pay retail sales tax or use tax on vehicle purchases if they take delivery of the vehicle at the seller’s location or another location outside their Indian Country.

Buying from an auto dealership – The Retail Sales/Use Tax Exemption Certificate for Vehicles Sold to Enrolled Tribal Members by Auto Dealers (pdf) form must be used to document exempt vehicle sales to tribal persons. Auto dealers and tribal members must complete this certificate to document that the vehicle was sold to an tribal member and the vehicle was delivered to the tribal member’s Indian Country.

Buying from a private party – Tribal members must complete the Use Tax Exemption Certificate for Vehicles Sold to Enrolled Tribal Members by Private Party (pdf). Tribal members/citizens are required to certify that the vehicle was delivered to the tribal member’s Indian Country. An original signed copy must be submitted to the Department of Licensing with title application.
