Washington Financial Statement is a document used by Washington state residents to report their financial activities to the state. It is especially important for taxpayers who are required to file a state tax return. There are three types of Washington Financial Statement: Individual, Business, and Estate/Trust. The Individual Financial Statement is used by individuals to report income, expenses, and assets. The Business Financial Statement is used by businesses to report income, expenses, and assets. The Estate/Trust Financial Statement is used by estates and trusts to report income, expenses, and assets. All of these statements are used to help the state of Washington assess a taxpayer’s financial situation and determine their tax liability.
