IRS Notices & Letters
“I got a CP11 notice claiming I miscalculated my taxes and now owe money, what specific documents do I need to mail back to prove my original return was correct?”
A CP11 notice usually means the IRS adjusted a return and believes there is still a balance due, so the response often depends on what item was changed and whether the original filing included all supporting records. Relevant documents may include the filed return, wage and income statements, receipts, schedules, and any correspondence that explains the figures reported. The notice itself, the IRS explanation of the adjustment, and any records tied to credits, deductions, or payments can all matter. In some cases, copies are enough, while other situations call for a written explanation or account transcript. Sitting down with a CPA for thirty minutes is usually enough to draw a clean line on this.
