A Form 843 is known as a Claim for Refund and Request for Abatement form. This form is sent to and recorded by the Internal Revenue Service in the United States. Someone can file this claim form if they want to dispute a certain tax, interest, penalty, fee, or addition on their taxes from that tax year.
This form should not be used for income tax refunds, FICA tax, FUTA tax, or RRTA tax. These taxes will require a different form. This form can be used for any other tax problems due to an error on the IRS’ part, illegal taxation, or other disputes. These issues could be related to employment taxes, estates, gifts, fees, or excising issues.
Include your personal identifying information so the IRS can view the issue. You should also list the date for the tax error, as well as the type of error you believed occurred. Explain why you believe this is an error. Be sure to sign the form before you send it off to the IRS.
Form 843 is commonly used to ask the IRS to refund: tax other than income, estate, or gift tax; fees; penalties paid; taxes withheld in error and unadjusted by your employer; and Section 6715 penalties for misuse of dyed fuel. Â Form 843 is also used to ask the IRS to abate interest, penalties or additions to tax caused by IRS error or delay, incorrect written advice from the IRS; penalties for unreasonable cause; FUTA tax; and certain excise taxes.Â
A Form 843 contains the following sections:
Form 843 only applies to certain types of tax, interest, penalties, and fees. Â You cannot use Form 843 to:
