Professional Services & Consultants Bookkeeping in Washington

Whether professional services & consultants services are taxable in Washington is the question that catches people out — states differ enormously, and several have been broadening what counts. No income tax, but the Business and Occupation tax applies to gross receipts by activity classification and is reported alongside sales tax. We code service revenue separately from any product revenue so the treatment is explicit rather than assumed.

Economic nexus in Washington is $100,000 in sales. For professional services & consultants, that threshold is the one to watch, because it is reached by selling into the state — no office, no staff, no physical presence required. Once you cross it you are expected to register with the Washington Department of Revenue and begin collecting. We track your Washington sales against it and tell you before you cross, not after.

Registering to do business in Washington runs through the Washington Secretary of State, with tax accounts through the Washington Department of Revenue and employer accounts through the Washington Employment Security Department. Washington treats these as wholly independent, so being in good standing with one says nothing about the others — and the sales tax account is the one that accrues a real balance while you are not looking.

The Washington statewide base rate is 6.5%. Local rates stack on top and are generally sourced to the delivery address, so the effective rate varies within the state. Getting sourcing right is what keeps the liability account matching what you actually collected.
