Washington Receipt for Blocked Account (GR-8A) is a document issued by the Washington State Department of Revenue to certify that a taxpayer's account has been blocked. This document is used to provide evidence that the taxpayer has paid their taxes and that the account has been blocked. It is also used to prevent the taxpayer from using the account for any other purpose until the taxes are paid in full. There are two types of Washington Receipt for Blocked Account (GR-8A): one for an individual taxpayer and one for a business taxpayer. The individual receipt is used to block an individual taxpayer's account, while the business receipt is used to block a business taxpayer's account. Both receipts provide evidence that the taxpayer has paid their taxes and the account has been blocked. They also prevent the taxpayer from using the account for any other purpose until the taxes are paid in full.
