Washington Pension Benefits Questionnaire is a form used to assess the eligibility of Washington State residents for retirement pension benefits. The questionnaire is required to be completed by all individuals who wish to receive benefits from the Washington State Department of Retirement Systems. There are three different types of Washington Pension Benefits Questionnaire: the Standard form, the Simplified form, and the Enhanced form. The Standard form is used for most applicants, and covers basic information such as Social Security Number, date of birth, current address, and prior employment. The Simplified form is for applicants who have limited financial information, and only requires basic information such as address, date of birth, and the last four digits of the Social Security number. The Enhanced form is for applicants with more complex financial information, and requires information such as sources of income, investments, and real estate ownership.
