What is the CP959 notice?

The CP959 notice is sent by the IRS to inform a business owner that they have failed to file a required business contribution plan return. The IRS uses this notice to remind businesses of their filing obligations and to prompt them to submit the necessary documents. The key phrase in this notice is, “Usted no radicó su planilla de contribución de negocios identificada en este aviso,” which translates to “You did not file your business contribution return identified in this notice.”
This notice is typically sent after the IRS has reviewed its records and found that a business has missed filing a specific form or return that was required for its tax year. Failing to file business tax returns can result in penalties, interest, and even legal consequences if not resolved promptly.

How the CP959 notice affects your business

When you receive a CP959 notice, it means that the IRS has not received a business tax return that you were obligated to file. This can cause immediate financial consequences, including penalties and interest on unpaid taxes. More importantly, it can affect your business’s tax compliance status, which could lead to further scrutiny from the IRS.
Failing to address the notice quickly could also cause long-term damage to your business’s financial health. The IRS may assess estimated taxes based on their records if you do not submit the necessary return. Additionally, unfiled tax returns could hinder your ability to obtain business loans or affect your credit standing.

Common reasons for receiving a CP959 notice

There are several reasons why you might receive a CP959 notice, including:
– Failure to file: You may have missed filing a required business contribution return, such as a form related to corporate income taxes or employment taxes.
– Incorrect filing: The IRS may not have received your return due to errors, such as mailing it to the wrong address or submitting it electronically with incorrect information.
– Late filing: Even if you eventually file the return, if it was submitted past the due date, the IRS may still issue this notice to ensure compliance.
Understanding why you received this notice is critical in determining your next steps.

Pro tip

  • Always keep a copy of your tax returns and receipts. If you receive a CP959 notice, having these documents handy can help you quickly resolve any discrepancies with the IRS.

What should you do when you receive a CP959 notice?

Receiving a CP959 notice is a call to action. Here’s a step-by-step guide to address it promptly:
1. Read the notice carefully: Ensure you understand which tax return is missing and why the IRS issued the notice.
2. Verify your records: Check your tax records to confirm whether you filed the return in question. It’s possible you submitted it, but there may have been an issue with the IRS receiving or processing it.
3. File the missing return: If you have not filed the required return, prepare and submit it immediately. Be sure to follow the IRS instructions carefully to avoid further delays or penalties.
4. Contact the IRS if necessary: If you believe there was an error and you did submit the return, call the IRS to clarify the situation. Provide any supporting documentation, such as proof of filing.
5. Pay any penalties or interest: If the IRS has assessed penalties or interest due to the late filing, make arrangements to pay these amounts or request a payment plan if necessary.

Pro tip

  • Respond to IRS notices promptly. Delays in filing or responding can lead to additional penalties and interest, so act as soon as you receive a notice.

How to respond to the CP959 notice

Steps to take when responding to a CP959 notice

The best way to resolve the CP959 notice is by responding quickly and accurately. First, you’ll want to ensure that the IRS receives the missing return as soon as possible. Here’s how to respond:
1. Review the notice thoroughly: The IRS provides detailed instructions on what is missing and how to file the return. Take the time to understand exactly what is required.
2. Submit your tax return: If you’ve determined that you have not filed the return, prepare it and submit it according to the IRS guidelines. Be sure to include any supporting documentation, such as prior year tax returns or financial statements, if needed.
3. Contact the IRS: If there’s a discrepancy or you believe you’ve already filed the return, call the number listed on the notice to discuss the issue with a representative. Keep a record of the call, including the date, time, and the name of the IRS agent you spoke with.
4. Consider professional assistance: If you are unsure how to file the return or believe the situation is complex, consult a tax professional who can guide you through the process.

Other ways to handle a CP959 notice

While submitting the missing return is the primary way to resolve the CP959 notice, there are additional steps you can take to ensure the issue is handled effectively:
– Request an extension or payment plan: If you cannot file the return immediately or if the IRS assesses taxes and penalties that you cannot afford to pay in full, you can request an extension or set up a payment plan with the IRS.
– Enlist the help of a tax professional: A certified public accountant (CPA) or tax attorney can provide valuable assistance in handling your case, especially if the notice involves complex issues like unfiled returns for multiple years.
– Respond in writing: If you need more time to resolve the issue, you can submit a written explanation to the IRS explaining why the return is late and requesting penalty relief. Include supporting documents where possible to strengthen your case.

Pro tip

  • If you’re unsure how to proceed, consult a tax professional. A CPA or tax attorney can provide guidance on resolving complex tax issues and help you avoid future problems.

Further support options for addressing the CP959 notice

If you need help resolving your CP959 notice, there are several resources available to assist you:
1. Contact a tax professional: CPAs and tax attorneys are well-equipped to help you respond to IRS notices and file any missing returns. They can also represent you in discussions with the IRS.
2. Visit the IRS website: The IRS has a wealth of information on its website, including specific instructions for handling unfiled returns. You can find forms, deadlines, and other resources that can help.
3. Reach out to the Taxpayer Advocate Service (TAS): If you’re having trouble resolving the issue, the TAS is an independent organization within the IRS that helps taxpayers navigate complex issues. They may be able to assist you if you’re facing financial hardship or if you believe the IRS is being unresponsive.

Potential penalties or next steps if you don’t respond

Ignoring the CP959 notice can have serious consequences for your business. Here’s what could happen if you fail to take action:
– Accumulating penalties and interest: The IRS will continue to charge penalties and interest on any unpaid taxes related to the unfiled return. These fees can add up quickly, increasing your overall tax liability.
Tax lien or levy: If you ignore the notice for an extended period, the IRS may place a lien on your business assets or even seize funds from your business bank accounts.
– Inability to apply for loans or credits: Banks and lenders often require businesses to be in good standing with the IRS before approving loans. Unresolved tax issues can hurt your chances of securing business financing.
To avoid these issues, it’s crucial to respond promptly and resolve any outstanding tax returns.

What potential outcomes are possible?

Once you respond to the CP959 notice, several outcomes are possible, depending on your situation:
– If you file the missing return: The IRS will process it, and you may need to pay any taxes owed along with penalties and interest.
– If the IRS made an error: In some cases, the IRS may determine that the notice was issued in error, such as if they discover that the return was filed but not properly processed. In such cases, the IRS will update its records, and no further action will be required from you.
– If your business owes taxes: The IRS may require you to make payments or set up a payment plan to clear your tax debt.
In any case, resolving the issue as quickly as possible will prevent further complications.
