Tips For Writing Letters To The IRS
Be Clear And Concise
Start with a brief header that repeats the IRS notice number, the tax year in question, and the taxpayer’s identification (use only the last four digits of your SSN/Tax ID). In the first paragraph, state why you are writing—whether to explain an item, correct an error, or submit requested documents. Keep sentences short and factual; avoid lengthy narratives that may obscure the central point.
Organize Supporting Documents
Create a clear list of enclosures and label each attachment (e.g., Exhibit A: Bank Statement, Exhibit B: Corrected 1099). Refer to these labels in the body of your letter when explaining a specific point. If you are submitting multiple pages, staple or bind them together and include a cover page that lists the documents by exhibit number.
Use Professional Tone And Exact Dates/Amounts
Record the exact dates, amounts, form numbers, and notice identifiers. Instead of saying “last year” or “a few months ago,” write exact dates and amounts (e.g., “$2,350 received on 03/15/2024, reported on Form 1099-INT”). This precision helps IRS reviewers match your explanation to their records and reduces back-and-forth.
Provide A Single Requested Outcome
Tell the IRS what you want them to do—accept the corrected amount, remove a penalty, or adjust the account balance—and base that request on the evidence you supply. If you expect a refund, state the method of refund delivery you prefer or confirm the bank account information only when it is requested through secure channels.
Keep Copies And Track Delivery
Always keep a complete copy of every letter and enclosure you send. Use certified mail with return receipt or another trackable method if the matter is time-sensitive or likely to affect penalties. Note the date you mailed or electronically submitted the response, and retain postal or tracking records.
Follow-Up And Be Responsive
If the IRS requests additional information, respond quickly, using the same formatting and labeling approach. If you receive no acknowledgment within a reasonable period (typically 30–60 days for mailed submissions), call the phone number on your notice and reference your original correspondence date and tracking number.
