Notice Overview

The Notice of Deficiency, Notice CP3219A (also referred to as 90-Day Letter or the taxpayer’s ticket to the Tax Court), is a taxpayer’s legal notice that the IRS is proposing a deficiency (balance due). 

This notice or letter may include additional topics that have not yet been covered here. Please check back frequently for updates.

What does this mean to me?

The Statutory Notice of Deficiency Notice CP3219A (also referred to as 90-Day Letters), is a taxpayer’s legal notice that the IRS is proposing a deficiency (balance due). This notice provides taxpayers with information about their right to challenge proposed IRS adjustments in the United States Tax Court by filing a petition within 90 days on the date of their notice (150 days if the notice is addressed to a person outside the United States). 

If the IRS is proposing to adjust the amount of tax you owe, you will typically be sent a statutory notice of deficiency informing you of the proposed change. Because this notice provides you with the right to challenge the proposed adjustment in the Tax Court without first paying the proposed adjustment, the statutory notice of deficiency is often considered “your ticket to the Tax Court.” 

The IRS is required to send a statutory notice of deficiency to a taxpayer’s last known address by certified or registered mail. The last known address is generally the address that appears on your most recently filed and properly processed tax return unless the IRS is given clear and concise notification of a different address. Form 8822, Change of Address, can be used by taxpayers to change their address with the IRS. 

The notice of deficiency must describe the basis for, and identify the amounts (if any) of, tax dueSometimes, but not always, the IRS includes penalties in the notice of deficiency, but does not include interest.  The IRS will ultimately send a bill for the tax due, interest, and any applicable penalties. 

How did I get here?

You received Notice CP3219A because the IRS completed the examination of your tax return and proposed changes to the amount of tax you owe. You have either not responded or have not provided a signed agreement consenting to these changes. Without your consent, the IRS cannot assess the proposed deficiency without first providing you an opportunity to challenge these adjustments by filing a petition with the Tax Court.

What are my next steps?

You should review the complete audit report enclosed with your letter. You should determine if you agree with the proposed changes or wish to file a petition with the Tax Court to dispute the adjustments made by the IRS. If you agree, sign and return Form 5564, Notice of Deficiency-Waiver, you received with your Notice CP3219A.  You can choose to pay some or all of the liability now, or you can choose to receive a bill from the IRS. 

If you do not agree with the adjustments and intend to file a petition, you should review the information provided in your letter, along with the information and instructions available on the United States Tax Court website. The necessary forms can be found on this website, along with a Petition Kit. There is a fee for the filing of a petition; however, you may file an Application for Waiver of Filing Fee with the Tax Court to request the filing fee be waived. To petition the Tax Court, you must send your petition to the United States Tax Court (not the IRS) within the 90-day (or 150-day) period shown on your notice. This 90-day (or 150-day) period is the time period prescribed by law and cannot be extended by the IRS. If you miss the deadline, the Tax Court can’t consider your case and the proposed tax will be assessed, along with any applicable penalties and interest. If the 90th day (or 150th day) is a Saturday, a Sunday, or a legal holiday in the District of Columbia, your petition will still be timely if filed on the next business day which is not a Saturday, Sunday, or legal holiday. 

The notice of deficiency advises you of your right to contact the Taxpayer Advocate Service. If you exercise this right, it does not extend the time you have to file a petition with the Tax Court.  In addition, the Taxpayer Advocate Service does not have the authority to determine the tax deficiency.
