If you received a CP: 13 notice titled: We Changed Your Return, it means IRS changed some of the information on your income tax return. The changes we made are outlined in the tax statement on the first page of the notice. You should review these changes and compare them with the information on your copy of your income tax return. Remember, the changes we made may cause some other items on your return to change also, so you should review your entire return. We explain why we made the changes on the second page of the notice. Please read this section carefully.

You don't need to respond to this notice unless you believe that we have made a mistake in our figures or that we haven't considered some important information. If this is the case, please call 1-800-829-8815. If possible, have a copy of your tax return and the notice available when you call.

When the amount you owe is less than $5, it is our policy to disregard it. When the refund is less than $1, it will be sent to you upon request.

If you normally make estimated tax payments you should check over the way you figured how much to pay, because the changes we made to your income tax return may change the amount of the estimated tax payments you'll need to make this year. If you need more information about estimated tax payments, you may order Publication 505 by calling 1-800-829-3676.
