What is the CP255 notice?

The CP255 Notice informs taxpayers about an issue or discrepancy with their tax return or account that needs resolving. It serves as a warning that something requires attention for the IRS to process the tax return correctly. Common reasons for a CP255 Notice include:
  • Errors on the tax return, such as incorrect calculations or missing details.
  • Discrepancies between information on the tax return and records from the IRS or other agencies.
  • Missing documentation to support claims made on the tax return.
  • Failing to file a tax return when required.
The notice typically specifies what needs correction and provides instructions on addressing the issue. Ignoring the notice can cause delays, penalties, or even enforcement actions.

Common reasons for receiving a CP255 notice

Tax return errors

Errors on the tax return often trigger a CP255 Notice. These can include math mistakes, incorrect tax credits, or inconsistencies in reported income. The IRS compares your tax return with other records to ensure accuracy, and any differences can prompt a CP255 Notice.

Discrepancies in reported income

The IRS may send a CP255 Notice if your reported income does not match information from employers, financial institutions, or other sources. For instance, if you forget to include income from a side job or freelance work, this can cause a discrepancy.

Missing or incomplete documentation

Sometimes, the IRS asks for additional documentation to verify claims on your tax return, such as deductions, credits, or exemptions. If the original filing lacks these documents, the IRS may issue a CP255 Notice requesting more information.

Failure to file a required tax return

The IRS might send a CP255 Notice if it believes you needed to file a return but didn’t. This situation could arise if your income exceeded filing thresholds, but you failed to submit a return on time.

Pro tip

Keep a detailed record of all communications with the IRS, including dates, names of representatives, and what was discussed. This can be helpful if you need to reference past conversations or resolve disputes.

Steps to take when you receive a CP255 notice

When you get a CP255 Notice, act quickly to resolve the issue and avoid penalties. Here’s what to do:
  • Read the notice carefully: It will specify the issue and what steps you need to take.
  • Verify your records: Check your tax return and any relevant documents to ensure the information you provided is accurate.
  • Gather required documentation: If the IRS requests more documents, collect them and make sure they are complete.
  • Respond by the deadline: Address the issue before the deadline to avoid penalties or interest.
If you feel unsure about what to do, consult a tax professional for guidance.

How to respond to the CP255 notice

Correcting errors on your tax return

If the notice points out errors, you may need to file an amended return (Form 1040-X) to correct them. Submit the corrected return with any additional documentation that supports the changes. Follow the instructions on the notice and send the corrected information by the deadline.

Providing missing information or documentation

If the notice specifies missing documents, gather them and send them to the IRS along with a copy of the CP255 Notice. Make sure all documents are clear and readable to avoid delays. Include a brief explanation if needed to clarify any discrepancies.

Addressing discrepancies in reported income

If the CP255 Notice results from discrepancies in reported income, verify the accuracy of the income listed. File an amended return to correct any mistakes. If your records align with what you reported, provide documentation to support your original return.

Responding if you missed filing a required return

If the IRS believes you needed to file a return but didn’t, file the missing return as soon as possible. Include all necessary documents and follow any additional instructions in the notice.

Pro tip

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

Further support options for addressing the CP255 notice

If you need help addressing a CP255 Notice, you have several options:
  • Consult a tax professional: A CPA or enrolled agent can help you understand the notice and guide you through the steps needed to resolve the issue.
  • Contact the IRS: If you need more information, call the IRS using the contact details provided in the notice.
  • Use a taxpayer advocate: The IRS offers a Taxpayer Advocate Service that provides free assistance to individuals who struggle to resolve tax issues.

Potential penalties or next steps if you don’t respond

Ignoring a CP255 Notice can lead to serious consequences, such as:
  • Penalties for late filing or payment if you miss deadlines.
  • Interest charges on unpaid taxes.
  • Enforcement actions, like wage garnishments or tax liens, if the issue remains unresolved.
Address the CP255 Notice promptly to avoid these penalties and resolve the issue efficiently.

Pro tip

Use certified mail when sending documents to the IRS to ensure proof of delivery. This way, you have a record of when the IRS received your response, which is crucial for meeting deadlines.

What potential outcomes are possible?

The outcome of responding to a CP255 Notice depends on the specific issue that caused it. Possible results include:
  • Corrected tax return: If errors existed, the IRS may process your amended return without penalties if you submit it promptly.
  • Revised tax assessment: The IRS might adjust your tax liability if there were discrepancies in reported income.
  • Account remains unchanged: If you provide enough documentation to support your original tax return, the IRS may conclude no further action is needed.
In all cases, addressing the CP255 Notice quickly helps resolve the issue and minimize disruptions.

Frequently asked questions

What should I do if I disagree with the CP255 notice?

If you disagree with the information in the CP255 Notice, review your tax records and gather any documents that support your position. Contact the IRS using the phone number provided on the notice to discuss the issue and provide your supporting documents. You may need to submit a written explanation along with additional evidence to resolve the dispute.

Can I get help resolving a CP255 notice if I cannot afford a tax professional?

Yes, if you cannot afford a tax professional, you can seek free assistance through the IRS’s Taxpayer Advocate Service, which offers support to individuals facing difficulties resolving tax issues. You may also find free or low-cost help from local organizations, such as the Volunteer Income Tax Assistance (VITA) program or Low-Income Taxpayer Clinics (LITCs).

How long does it take for the IRS to process a response to a CP255 notice?

The processing time for responses to a CP255 Notice can vary. Typically, it may take 6 to 8 weeks for the IRS to review your documents and update your account. However, more complex cases or incomplete submissions can result in longer processing times. To avoid delays, ensure all requested documentation is included and accurate when submitting your response.

Will I receive penalties if I respond to the CP255 notice after the deadline?

If you respond after the deadline, you may face penalties for late filing or late payment, depending on the nature of the issue. The IRS may apply interest to any unpaid tax amount from the original due date until the payment is made. In some cases, you can request a penalty waiver if you have a reasonable cause for the delay, such as a serious illness or natural disaster.

Can I request an extension to respond to a CP255 notice?

Yes, you can request an extension if you need more time to gather the required documentation. Contact the IRS using the information provided on the notice and explain your situation. While the IRS may grant additional time to respond, requesting an extension does not stop interest or penalties from accruing on any unpaid taxes, so it is best to act as quickly as possible.
