The CP11 notice is used generally because the IRS believes there may be a miscalculation on your return. You may owe money on your taxes as a result of these changes.
What do I need to do with my notice?
Read your notice carefully. It will explain the changes the IRS has made and why you may owe money on your taxes.
- If you agree with the changes made.
- Pay the amount owed by the date on the notice.
- Visit Payments on the IRS webpage for electronic payment options.
- Make payment arrangements if you can't pay the full amount you owe with the IRS. You can do this online using the Online Payment Agreement tool.
- Correct the copy of your tax return that you kept for your records, but do not send it to the IRS.
- If you don't agree with the changes made, contact the IRS directly within 60 days from the date of your notice.
- By telephone: Call the IRS at the telephone number shown on your notice. The IRS states that fastest way to resolve many return errors is by telephone. Some cases require additional information that you may provide verbally.
- By mail: Please include a copy of the notice along with your correspondence or documentation. The IRS asks that you allow 30-60 or more days for a resolution.
What do I need to do if I disagree with the changes?
If you disagree with the changes the IRS has made to your return, contact them directly at the toll-free number show at the top right corner of your notice, or respond by mail to the address on your notice. If you write to the IRS, include a copy of the notice along with your correspondence or documentation.
According to the IRS, they will reverse most changes made if they increased the amount you owe or if your return requested a refund. However, you must contact them within 60 days from the date of your notice to request the reversal. You don’t need to prove an explanation or additional documents when you request the reversal, but they will consider any information you provide them.
If you don’t contact the IRS within the 60-day period, the changes won’t be reversed and you’ll lose your right to appeal our decision before payment of the tax. Following the payment of the tax, you may file a claim for refund to dispute the changes. Generally, you must submit the claim within 3 years from the date you filed the tax return, or within 2 years from the date of your last payment for this tax, whichever is later.
