Organized tax records make preparing a complete and accurate tax return easier. It helps you avoid errors that lead to processing delays that slow your refund and may also help you find overlooked deductions or credits.

Forms W-2 from your employer(s)
Forms 1099 from banks, issuing agencies and other payers including unemployment compensation, dividends, distributions from a pension, annuity or retirement plan
