In order to amend your tax return you need: File Form 843, Claim for Refund and Request for Abatement instead. Do not submit this document to request a refund of interest and penalties, or addition to the tax you have already paid. Fill out a separate form for every year you are changing information for. When you submit an amendment on the 1040-X tax return, it is considered your tax return form for that year. Claim a carryback because of a loss or unused credit.Change the amounts adjusted by the IRS (do not include any penalties or interest on this form as they are adjusted separately) and.Make some elections after the due date.
