To write a letter to the Internal Revenue Service, include your name and contact information, a statement of intent referencing the relevant tax period, a detailed summary of any information you are referring to or appealing, facts that support your position, and a signed penalties of perjury statement, as indicated on the IRS website. Present your claims and supporting information in a clear and straightforward manner, and send copies of any relevant documents.
If you are responding to a letter the IRS sent you, follow all given directions given. Write in a polite, respectful tone, and outline your request clearly and concisely, explains Success Tax Relief. If you are writing to appeal an IRS decision, its website requests that you cite specific publications, laws or evidence as it pertains to your case, and be sufficiently prepared to represent your evidence and defend your case. If you are responding to a letter that you received, include a copy of it with your response.
All correspondence must include a "penalties of perjury" statement that explicitly indicates that all information and documents provided are accurate to the best of your knowledge, explains the IRS. A sample statement is available from IRS.gov. Sign your name by hand under the statement.
