To provide a comprehensive understanding of the changes required, I have enclosed the following supporting documents: 1. Updated W-2 forms and 1099 statements: These documents reflect the accurate income received during the tax year and include any additional sources of income that were initially overlooked. 2. Proof of deductible expenses: I have included receipts and relevant documentation for deductible expenses that were previously omitted. Please note that these expenses are legitimate and were incurred during the relevant tax year. 3. Explanation of changes: In a separate document, I have outlined the details of the changes made. This includes a breakdown of the additional income and expenses, as well as the recalculated figures for my tax liability. I kindly request your assistance in processing this supplement to my North Carolina Tax Return. I understand that this may require additional time and effort, but I am confident that resolving this matter accurately is in the best interests of both parties. Please let me know if there are any further steps or documentation required on my part to facilitate this process. I would greatly appreciate it if you could acknowledge receipt of this letter and inform me of the necessary actions to take next. Thank you for your prompt attention to this matter. I look forward to your response and appreciate your understanding and cooperation. Sincerely, [Your Name]
