The Notice of Deficiency, commonly known by its IRS form code CP3219A, is a formal letter sent by the IRS when it determines that you may owe more tax than reported on your filed return. This notice signifies a proposed change and gives you a critical opportunity to challenge the IRS’s findings before they finalize the assessment.
Why Does the IRS Issue a Notice of Deficiency?
IRS discrepancies arise from audits or reviews of filed tax returns, uncovering issues such as unreported income, incorrect deductions, or calculation errors. When the IRS has strong evidence of an underpayment, they issue a Notice of Deficiency instead of directly assessing additional tax. This process formally notifies the taxpayer and allows for dispute resolution.
How the Notice of Deficiency Process Works
- IRS Review: After you file your tax return, the IRS reviews the information.
- Identification of Issues: If discrepancies are found, the IRS prepares the CP3219A notice.
- Notice Delivery: The IRS mails the notice to your last known address.
- Response Window: You have 90 days from the date on the notice (150 days if the notice is addressed outside the U.S.) to respond.
- Response Options: Within this timeframe, you can:
- Agree to the proposed changes and pay the amount owed.
- File a petition to the United States Tax Court to dispute the IRS’s determination without paying first.
- Contact the IRS for clarification or provide additional documentation.
- Failure to Respond: If you do not respond within the deadline, the IRS will assess the tax and may begin collection actions such as liens or levies.
Example Scenario
Suppose you claimed a home office deduction on your 2023 tax return. The IRS reviews your return and decides you do not qualify for this deduction, calculating you owe an extra $1,200. They send a CP3219A Notice of Deficiency explaining the rationale. You then have 90 days to pay the amount, agree with the IRS, or challenge the decision in Tax Court.
Who Can Receive a Notice of Deficiency?
Any taxpayer — individuals, businesses, sole proprietors, partnerships, and corporations — can receive this notice when the IRS believes additional taxes are owed.
Tips for Handling a Notice of Deficiency
- Stay Calm and Act Promptly: The notice is serious but offers a clear path to respond.
- Review the Notice Thoroughly: Understand the IRS’s adjustments and the reasons behind them.
- Gather Supporting Documentation: Collect evidence supporting your original return, such as receipts, bank statements, or contracts.
- Adhere to the 90-Day Deadline: Missing this deadline limits your options and triggers automatic assessment.
- Consider Filing a Tax Court Petition: This allows you to dispute the IRS findings without immediate payment. Learn more about this process in our Tax Court Petition guide.
- Consult a Tax Professional: Tax attorneys and CPAs can help you navigate the complexities and improve your chances of a favorable outcome.
- Keep Copies of All Correspondence: Document your communications with the IRS for your records.
Common Misunderstandings
| Myth | Reality |
|---|---|
| Ignoring the notice will make it disappear. | Ignoring leads to formal tax assessment and possible collection enforcement, including liens and levies. |
| Paying immediately means you admit the IRS is correct. | You can pay under protest and later file a refund claim if you disagree. |
| The IRS will negotiate after the 90-day window. | The IRS often finalizes the assessment and may begin collection if no timely response is received. |
| The notice only follows an audit. | The IRS may issue it after a review or audit; not all notices result from full audits. |
Frequently Asked Questions
