It sounds like you received and letter from the IRS proposing an adjustment to your tax return. First you need to determine if the IRS is correct. This is often the case due to not including a W-2, or a 1099-DIV, etc. that you may not have received in the mail. If you determine that the IRS is correct, then you simply need to pay (if you owe) or if the change benefits you, agree with the change and they will send you a refund. If you disagree with the IRS, you should notify them in writing. For help resolving the issue go to Contact Us
