Washington Creditors Receipt (WAR) is a form issued by the Washington State Department of Revenue to acknowledge when a debt payment is received. The WAR is a type of proof of payment, and it is used to document the transaction between the debtor and the creditor. This form is used as proof of payment to settle disputes, should they arise. There are two types of Washington Creditors Receipts: a standard WAR and a WAR with lien attached. The WAR with lien attached is used to secure the debt payment and is similar to a promissory note. The WAR must include the taxpayer’s name, address, phone number, Taxpayer ID, amount of the payment, date the payment was made, and the name of the creditor. The WAR must also be signed by the debtor and a representative of the creditor.
