What is the CP812 IRS notice?

The IRS sends a CP812 Notice when it detects mistakes on your tax return that need correction. The notice explains the specific changes, the reasons behind them, and any adjustments to your tax or refund. Errors can include incorrect figures or missing information. The IRS corrects these automatically.
The CP812 Notice aims to inform you about these changes and how they affect your return. The notice may indicate one of these outcomes:
  • You qualify for a refund due to an error that increased your refund amount.
  • You owe more taxes because of the corrections.
  • Your overall tax doesn’t change, but adjustments were needed to fix discrepancies.

Pro tip

Set up IRS account alerts online for real-time notifications about any changes to your tax return or account. This helps you stay informed about adjustments and due dates.

How does the CP812 notice affect you?

A CP812 Notice can impact your tax situation depending on the adjustments made. Here’s how it might affect you:

Potential outcomes

  • Refund adjustments: If the corrections increase your refund, expect the revised amount in 4-6 weeks, assuming no other debts need collection.
  • Additional tax due: If the changes raise your tax liability, the notice will specify how much you owe, including interest or penalties.
  • Unchanged tax liability: Sometimes, adjustments don’t change your owed or refunded amount. The notice will still explain the reasons for the changes.

Common reasons for receiving a CP812 notice

The IRS may issue a CP812 Notice due to different types of errors, such as:
  • Math mistakes: Arithmetic errors that affect income, deductions, or credits.
  • Incorrect or missing information: Missing Social Security numbers, tax ID numbers, or other details.
  • Inaccurate tax credit claims: Mistakes in claiming credits like the Earned Income Tax Credit (EITC) or Child Tax Credit (CTC).
  • Errors in reported income or deductions: Discrepancies between the amounts you reported and information from third parties.

Steps to take when you receive a CP812 notice

Follow these steps to resolve the issue after getting a CP812 Notice:

Review the notice thoroughly

Read the notice carefully to understand the changes made to your tax return. The CP812 will list the corrections, why they occurred, and how they impact your taxes. Compare these changes with your original return to identify any differences.

Compare the IRS’s corrections with your original tax return

Check the IRS changes against your original records. This comparison helps you see any discrepancies and understand the reasons for adjustments. Ensure the information aligns with your financial documents.

If you agree with the changes

If the IRS corrections look accurate, no further action is needed. You should receive any revised refund amount within 4-6 weeks. Pay any additional taxes by the due date to avoid extra interest and penalties.

If you disagree with the changes

If you disagree with the IRS adjustments, respond within 60 days of the notice date. Here’s what to do:
  1. Contact the IRS: Call the number on the notice to discuss the changes. The representative can explain the corrections and help you dispute them.
  2. Provide supporting documentation: If you think there’s an error, submit documents that support your original return.
  3. Consider filing an appeal: If unresolved, you can appeal through the IRS Office of Appeals. Refer to IRS Publication 5 for guidance on your appeal rights.

Pro tip

Keep copies of your tax returns and notices for at least three years. These records help you resolve issues or verify details if you need to dispute adjustments.

How to respond to the CP812 notice

Act quickly to avoid complications. Here’s how to respond to a CP812 Notice:

Confirm receipt of the notice

Make sure you received the notice and that it’s addressed to you. The IRS sends notices by mail, and any differences could indicate problems with your tax records.

Contact the IRS if needed

Reach out to the IRS if you have questions about the notice or need clarification. Use the contact information provided in the notice.

Keep a copy of the notice for your records

Save the CP812 Notice along with your original tax return and other documents submitted to the IRS. This documentation can help if you need to reference the notice later.

Understanding your appeal rights

If you disagree with the IRS corrections, you can appeal. Here’s how the process works:

Filing an appeal

Follow these steps to file an appeal:
  1. Prepare a written protest: Include the reasons you disagree and provide supporting evidence like tax forms and receipts.
  2. Submit your appeal on time: File the protest within 60 days to ensure the IRS reviews your case.
  3. Wait for a response from the IRS Office of Appeals: The appeals office will review your appeal and notify you of their decision.

When an appeal may be denied

Appeals may be denied if you don’t provide enough documentation or if the IRS finds your protest lacks merit. In such cases, consider getting help from a tax professional.

Further support options for addressing the CP812 notice

If you’re unsure how to respond to a CP812 Notice, use these resources:
  • Consult a tax professional: A CPA or enrolled agent can guide you through the process and explain your options.
  • Utilize IRS resources: The IRS website offers tools and FAQs to help you understand various tax notices.
  • Contact the Taxpayer Advocate Service (TAS): If you face challenges resolving the issue, TAS may assist, especially if experiencing financial hardship.

Pro tip

Dispute an IRS notice promptly to avoid penalties. Providing accurate documents can speed up the resolution process.

Potential penalties or consequences if you don’t respond

Ignoring a CP812 Notice may lead to:
  • Delayed tax refunds: The IRS may hold your refund until you resolve the issue.
  • Interest and penalties: If you owe taxes, interest will accumulate, and late payment penalties may apply.
  • Possible enforcement actions: In serious cases, the IRS may use wage garnishment or bank levies to collect unpaid taxes.

What are the possible outcomes after you respond?

Your actions and the information you provide will determine the outcome:
  • If the IRS accepts your documents: Your account will be updated, and adjustments may be reversed, resulting in a refund or reduced tax liability.
  • If you owe additional taxes: Pay promptly to avoid further penalties. Consider setting up a payment plan if needed.
  • If errors persist: Get advice from a tax attorney or accountant for further help.
