Business & Occupation (B&O) Tax

The tax applies to the gross revenues of businesses at the rate of one-tenth of one percent, except those engaged in certain types of service industries (see TMC 5.08.030§(Q)) which shall pay at the rate of two-tenths of one percent. The tax for quarterly filers is due in four installments on the last day of January, April, July and October. If the gross proceeds of sales or gross income of the business from all activities is less than $5,000 per quarter, no tax is due. The tax for annual filers is due on the last day of January. If the gross proceeds of sales or gross income of the business from all activities is less than $20,000 per year, no tax is due.  All  businesses conducting business in Tumwater are required to file a quarterly or annual return, even if there has been no activity or no tax is due.
