Form 990-W is one of Federal tax forms that are documents used to report and file federal income taxes with the Internal Revenue Service (IRS) in the United States. These forms are used by individuals, businesses, and organizations to report their income, deductions, and other relevant information necessary for calculating their federal tax liability.
