RCW 60.28 mandates that the Department of Revenue certifies that all excise taxes have been paid in full before a public agency releases retainage withheld on public works contracts over $35,000.
When a public works project over $35,000 is completed, the public agency submits a Notice of Completion to the Department of Revenue.
Once the Department receives a Notice of Completion:
When all excise taxes due on the contract have been paid, a Certificate of Payment is issued by the Department to the public agency with a copy to the contractor. This notifies the public agency that state excise, sales and/or use taxes reported on the project have been paid and the Department is releasing their interest in the retainage.
