Summary:
A notice of deficiency, often referred to as an IRS 90-day letter, is a legal determination by the Internal Revenue Service (IRS) indicating that a taxpayer owes additional income tax, along with interest and penalties. This official written claim is issued when the IRS identifies discrepancies between a taxpayer’s return and their records. The notice serves as a legal determination and is crucial in the tax assessment process. To understand how a notice of deficiency works and its implications, continue reading this comprehensive guide.

Understanding a notice of deficiency

A notice of deficiency, also known as an IRS Notice CP2319A, is a formal notification from the IRS that asserts a taxpayer’s tax deficiency. It states that the taxpayer owes additional income tax, often accompanied by interest and penalties. This notice is issued when the IRS proposes changes to a tax return due to inconsistencies in the information reported by the taxpayer compared to their records.

How a notice of deficiency works

A notice of deficiency typically arises from discrepancies between the information provided by the taxpayer and data obtained from third-party filers like employers or financial institutions. If a taxpayer fails to respond to or successfully appeal a pre-assessment letter, known as a 30-day letter, the IRS proceeds with the notice of deficiency.
The notice outlines any adjustments made and provides details on how the deficiency amount was calculated. It also explains the taxpayer’s options, which include either agreeing to the additional tax liability by signing a Waiver Form 4089 or challenging it in the U.S. Tax Court.
Often referred to as a “90-day letter,” this notice gives the taxpayer 90 days to dispute the tax assessment in Tax Court. The 90-day period is set by statute and cannot be extended. It begins from the date the notice of deficiency is mailed to the taxpayer’s last known address. The IRS is legally required to specify the last day a petition can be filed directly on the notice of deficiency. During the 90-day period or until a Tax Court decision becomes final, the IRS is prohibited from any assessment or collection activity.

Common triggers for a notice of deficiency

A notice of deficiency doesn’t randomly appear in a taxpayer’s mailbox. Several common triggers may lead to its issuance. Understanding these triggers can help taxpayers be proactive in addressing potential issues.

1. Discrepancies in third-party filings

One frequent trigger for a notice of deficiency is a discrepancy between a taxpayer’s reported income and the information provided by third parties, such as employers or financial institutions. For example, if you fail to report income from a job, a bank account, or investments, and the IRS receives this information from third-party sources, it can lead to an assessment of deficiency.

2. Failure to respond to a 30-day letter

Before the IRS issues a notice of deficiency, they typically send a “30-day letter.” This letter provides taxpayers with a 30-day window to address any proposed changes to their tax return. If you fail to respond within this period or successfully appeal the adjustments, it can escalate to the issuance of a formal notice of deficiency.

Options for responding to a notice of deficiency

Receiving a notice of deficiency may seem daunting, but taxpayers have options for responding and resolving the situation. It’s essential to understand these options to make informed decisions about how to proceed.

1. Agreement and payment

If you agree with the IRS’s assessment in the notice of deficiency, you can choose to pay the additional tax, interest, and penalties indicated in the notice. This often involves signing a Waiver Form 4089, acknowledging the changes and committing to payment. By doing so, you can avoid a lengthy legal process.

2. Filing a petition with the U.S. Tax Court

If you disagree with the IRS’s assessment, you have the option to file a petition with the U.S. Tax Court. This allows you to dispute the tax deficiency in a legal forum
. Keep in mind that you have a strict 90-day window from the date of the notice of deficiency to file this petition, as prescribed by law.

3. Seeking professional guidance

Tax law and IRS processes can be complex, making it challenging for taxpayers to navigate the system on their own. Seeking professional assistance, such as hiring a tax attorney or tax consultant, can be a prudent choice. They can help you understand your options, prepare necessary documentation, and represent your interests in dealing with the IRS.

The impact of a notice of deficiency on taxpayers

Receiving a notice of deficiency can have significant implications for taxpayers. It’s crucial to be aware of how this legal determination can affect your financial situation and take appropriate action.

1. Potential legal costs

If you choose to dispute the IRS’s assessment and file a petition with the U.S. Tax Court, be prepared for potential legal costs. Engaging in a legal process can involve attorney fees, court filing fees, and related expenses.

2. Accumulation of interest and penalties

During the period of dispute, interest and penalties can continue to accrue on the assessed tax deficiency. This can result in a larger financial obligation if the case is not resolved promptly.

3. IRS collection efforts

If a taxpayer does not respond to the notice of deficiency within the 90-day period and fails to reach an agreement with the IRS, the agency may initiate collection efforts. This could involve wage garnishments, bank levies, or the seizure of assets to satisfy the outstanding tax liability.
Understanding the potential outcomes and impact of a notice of deficiency underscores the importance of timely and informed decision-making when faced with this IRS notification.

Conclusion

A notice of deficiency is a pivotal step in the IRS’s tax assessment process. It serves as an official determination of a taxpayer’s tax deficiency and triggers a 90-day period in which the taxpayer can challenge the assessment. While it provides an opportunity to dispute the IRS’s findings, it’s essential to be aware of the associated legal challenges and costs.
Understanding your options and rights when receiving a notice of deficiency is crucial in managing your tax liabilities. Whether you choose to contest the assessment or agree to the changes, taking prompt action is key to a favorable resolution.
