RCW 82.32.070 requires all taxpayers to maintain a record of the Unified Business Identifier (UBI) account number of each contractor they hire to perform construction. For example, the law requires a general contractor to record the UBI number of all subcontractors. Taxpayers must keep record of the UBI numbers for at least five years. If a taxpayer fails to record the contractor's UBI number, the taxpayer will not be allowed to bid on a public works contract for two years. The taxpayer will also be subject to a penalty not to exceed $250.
