Tax Services in Washington for Small Businesses
Washington has no personal or corporate income tax, but replaces both with the Business & Occupation (B&O) tax, a gross receipts tax that applies based on revenue and varies depending on which classification your business activity falls under.
Getting classified wrong is one of the more expensive mistakes we see, since it directly changes the rate applied to every dollar of revenue.Sales tax adds another layer businesses have to track. Profitjets classifies your business activity correctly for B&O purposes, registers and files your sales tax at the right combined local rate, and tracks every deadline, so nothing gets filed under the wrong classification by default.

What Washington Businesses Say
B&O Classification Corrected After Years of Overpaying
"We'd been filed under a higher-rate B&O classification than what our actual activity qualified for. Profitjets caught it, corrected it, and we stopped overpaying."
Sales Tax Rate Matched to Actual Location
"Our combined sales tax rate was off because our registration hadn't been updated after we expanded. Profitjets fixed it to reflect our actual selling locations."
Multiple Revenue Streams Finally Classified Separately
"We have retail and service revenue mixed together and had been filing everything under one B&O classification. Profitjets split it out and reconciled both correctly."
