A city workgroup met over the summer of 2019 to review changes needed to the B&O model ordinance.
In the 2019 session, two bills passed that impact city B&O tax administration: HB 1403 related to service income apportionment and HB 1059 related to annual tax filing deadlines. The last major revisions to the B&O tax model ordinance took effect January 1, 2013.
The workgroup revised the model ordinance to include changes to RCW 35.102 and to reflect other changes made to state law since 2013. Cities must adopt mandatory changes to model ordinance with same effective date: January 1, 2020. Follow the links below to learn more.

Washington Department of Revenue
In addition to local B&O tax the state of Washington has a B&O tax, which is also a gross receipts tax remitted directly to the State. Tax is measured on the value of products, gross proceeds of sales, or gross income of the business.
The test for determining whether an out-of-state business is subject to Washington’s business and occupation (B&O) tax changed on July 1, 2017. The change extends Washington’s “economic nexus” standard to businesses engaging in a retailing activity. As a result, a business engaged in a retailing activity has nexus with Washington State either by having a physical presence in this state or by exceeding an economic nexus threshold. (HB 2163, Chapter 28, Laws of 2017, 3rd Special Session, Part III)
On March 14, 2019, Gov. Jay Inslee signed a bill that simplifies Washington tax responsibilities for out-of-state sellers without a physical presence in the state.
