What this notice is about We reduced or removed the penalty for underpayment of estimated tax reported on your tax return. What you need to do Review the account information in your notice. If you disagree with our adjustment, please contact us at the number shown on your notice. Frequently asked questions Why did you reduce or remove the penalty? (updated July 6, 2023) We reduced or removed the penalty because, according to our calculation, the penalty reported on your return is greater than the penalty due. Our calculation is based on information in our records at the time we processed your return. If your address is within a geographical area that was declared a federal disaster area, we may have applied an automatic waiver, which may have resulted in the reduction. What should I do if I disagree with the correction? (updated July 6, 2023) Call the toll-free number shown on your notice. Be sure to have any supporting information with you when you call. If we agree with your explanation, the assistor will tell you what to do next. The notice says that I will receive a refund, but I haven't received it yet. When will I receive the refund? (updated June 14, 2024) Before we can issue a refund, we're required to collect (offset) any other taxes you may owe. Additionally, your refund may be offset to pay child support or state taxes you owe, or to pay any other debts you legally owe that we are required to collect. We also might not mail your refund if you haven't filed the returns you're required to file. To check the status of your refund you may call the toll-free number shown on your notice or visit Where's My Refund? My spouse and I both received a CP30A for the same amount. Do we both need to pay? (added July 6, 2023) We sent each spouse a copy of the notice. Each copy shows the same information related to your joint account. If you owe a balance due, pay it only once. If you're due a refund, we'll issue it only once. What are my rights as a taxpayer? (added July 6, 2023) The Internal Revenue Code (IRC) gives taxpayers specific rights. The Taxpayer Bill of Rights groups these into 10 fundamental rights. See IRC Section 7803(a)(3). IRS employees are responsible for being familiar with and following these rights.
