General Contractors & Construction Accounting in Seattle

Contractor accounting in Seattle, WA is shaped by two things: the local industry mix and the state tax environment. Washington has no state personal income tax, but the Business and Occupation (B and O) tax applies to gross receipts, with no deduction for cost of goods or expenses.
