Washington Expands Sales Tax to IT Services, Marketing, and Online Classes

New Washington sales tax rules starting October 1 expand what counts as retail services, adding taxes to previously exempt business services
Newly taxed services include advertising, marketing, online classes, IT services, private security, and temporary staffing
Most personal services remain exempt including healthcare, legal, accounting, therapy, haircuts, massages, groceries, and prescription drugs
Small businesses must apply tax rates based on where services are received rather than where they are sold
The changes aim to modernize tax code and generate revenue from growing service sectors that previously contributed less to state taxes
