Effective June 1, 2010, there is a change in the length of time a business continues to have reporting obligations for business and occupation (B&O) tax.
A person who stops the business activity that created nexus in Washington now continues to have nexus for the remainder of that calendar year, plus one additional calendar year. (See RCW 82.04.220)
This “trailing” nexus provision applies to all business and occupation (B&O) tax classifications.
This legislation only changes trailing nexus for B&O taxes.
The trailing nexus period for retail sales tax (RST) is still four years, plus the current year, under WAC 458-20-193 (Rule 193).
